Aspects of this disclosure relate to mobile generators.
Solar panels have traditionally been installed in fixed locations where they can generate power which can then be distributed to the electrical systems. Many solar panels are also installed at fixed angles to keep installation and maintenance costs down. Some solar panels are transportable, such as those used for camping, camping vehicles, mobile security cameras, etc., but these solar panels usually are small in terms of electricity generated and require human interaction to set up.
Some aspects of this disclosure are directed to a mobile solar generator. In various examples, mobile solar generators can comprise a housing, wheels and outriggers coupled to the housing, a solar array including one or more solar panels that can receive electromagnetic radiation and generate electrical energy, a user interface, and a controller in communication with the user interface and other components.
Some mobile solar generators include an adjustable support pillar configured to extend from a housing and a multi-axis pivot connecting the solar array to the adjustable support pillar. In some such cases, the height of the solar array is adjustable via the adjustable support pillar. In some cases, the solar array is configured to move about at least two axes relative to the adjustable support pillar, and a height of the solar array is adjustable via the adjustable support pillar.
In some embodiments, a mobile solar generator includes a solar array drive system controllable by a controller. The solar array drive system can move the solar array, such as about the at least two axes. In some examples, the solar array drive system moves the solar array to track the sun. A mobile solar generator can include components such as a GPS and a compass to facilitate tracking the sun. For instance, in some examples, a mobile solar generator is portable, such as being towable behind a vehicle, and the mobile solar generator can be brought to and used at various locations and can face different directions. Components such as a GPS and compass can be used to determine motion of the solar array to track the sun given the location and facing direction the mobile solar generator, even if the mobile solar generator is brought to different locations.
In some examples, the solar array is movable between a stored solar array configuration and a deployed solar array configuration. In some examples, the stored solar array configuration facilitates easier transportation of the mobile solar generator, while the deployed solar array configuration increases the amount of power that the mobile solar generator can generate from the solar array.
In some embodiments, the mobile solar generator comprises a plurality of outriggers coupled to the housing. The outriggers include an arm extendable outwardly from the housing, a leg extendable downwardly from the arm's distal end, and a foot coupled to the leg's bottom surface. The outriggers can move between a stored outrigger configuration and a deployed outrigger configuration, wherein the foot of the outrigger extends to the ground. In some examples, the outriggers can raise the mobile solar generator such that one or more wheels of the mobile solar generator are raised off of the ground and can be adjusted to level the housing. In some examples, a controller controls the movement of the outriggers, for example, via one or more hydraulic actuators. In some examples, in response to command(s) received from the user interface, the controller causes the outriggers and solar array to move from their stored configurations to their deployed configurations.
Some embodiments of the mobile solar generator comprise a wind sensor, for example, supported by a sensor tower. In some such examples, the controller receives wind information from the wind sensor representative of a wind strength, and if the solar array is in the deployed configuration and the wind information satisfies a predetermined threshold, the controller moves the solar array into a safe mode configuration different from the deployed configuration. Moving the solar array to a safe mode can prevent damage that may otherwise occur due to high winds when the solar array is fully deployed.
An example solar array comprises a first section having a top surface and a bottom surface and comprising a first set of one or more solar panels and a second section having a top surface and a bottom surface and comprising a second set of one or more solar panels. The second section can be pivotable relative to the first section about an axis. In some cases, the solar array is movable between a closed configuration wherein the second section is positioned underneath the first section such that the bottom surface of the second section faces the bottom surface of the first section, and a deployed configuration the top surface of each of the first section and the second section are coplanar. In some such examples, moving the solar array from the closed configuration to the deployed configuration comprises rotating the second section 180 degrees about the axis. In some examples, the solar array comprises a four-bar linkage coupled to the first section and the second section and a linear actuator configured to move an element of the four-bar linkage to move the solar array between the closed configuration and the deployed configuration.
In some embodiments, the solar array comprises a first section having a top surface and a bottom surface and comprising a first set of one or more solar panels, a second section having a top surface and a bottom surface and comprising a second set of one or more solar panels, and a third section having a top surface and a bottom surface and comprising a third set of one or more solar panels, and is movable between a closed configuration and a deployed configuration. In some such examples, in the closed configuration, the third section is covered by the second section and the second section is covered by the first section, and in the deployed configuration, none of the first, second, or third sections are covered by any other of the first, second, or third sections and the top surface of each of the first, second, and third section face an outward direction. In some examples, as the solar array moves between the closed configuration and the deployed configuration, the first section and the third section remain parallel to one another.

Embodiments of the invention will hereinafter be described in conjunction with the appended drawings, wherein like numerals denote like elements.
The following detailed description is exemplary in nature and is not intended to limit the scope, applicability, or configuration of the invention in any way. Rather, the following description provides some practical illustrations for implementing exemplary embodiments of the present invention. Examples of constructions, materials, and/or dimensions are provided for selected elements. Those skilled in the art will recognize that many of the noted examples have a variety of suitable alternatives.
The mobile solar generator 100 includes a series of solar panels 102 in a solar array 116 supported by a housing 118. In some embodiments, the series of solar panels 102 are mounted to the mobile solar generator 100 via an adjustable support pillar with a multi-axis pivot (e.g., a gimbal) as described elsewhere herein. In some examples, solar array 116 is configured to move between a stored solar array configuration and a deployed solar array configuration.
Optionally, the mobile solar generator 100 can include a generator that runs on fuel (e.g., propane) in addition to the series of solar panels 102. In some examples, the generator is configured to generate electrical energy from a non-renewable source. In some embodiments, the generator comprises a propane generator, a diesel generator, or a fuel cell. In some examples, the generator comprises a 6.5 kW propane generator configured to output up to 54 amps at 120 VAC. The generator can be used as a backup generator or as a supplemental generator to provide power when the series of solar panels cannot provide enough power for a load and/or for charging one or more batteries by themselves. In some examples, the mobile solar generator 100 includes one or more batteries that can be used to power a load. In some embodiments, a mobile solar generator includes one or more batteries and a generator that runs on fuel and does not include any solar panels.
In examples which include a generator, the mobile solar generator includes a refillable fuel source container for storing fuel for the generator. For example, the mobile solar generator 100 of
In some examples, mobile solar generator 100 includes one or more inverters 105 configured to receive DC power (e.g., from one or more solar panels, from one or more batteries, and/or from a generator) and output AC power. In some examples, such one or more inverters comprises one or more off-the-shelf inverters. In various embodiments, inverters can be selected or otherwise configured to output AC power at any desired voltage and frequency. In some embodiments, inverters are configured to output between 100 VAC and 120 VAC at between 50 Hz and 60 Hz. In some embodiments, the mobile solar generator 100 is configured to output three-phase power. In some examples, the mobile solar generator is configured to output between 100 VAC and 150 VAC line to neutral and/or between 180 VAC and 220 VAC phase to phase. In an example embodiment, the mobile solar generator is configured to output 120 VAC in a single-phase output at 60 Hz, 208 VAC in a single phase output at 60 Hz, or 208 VAC in a three-phase output at 60 Hz. In some embodiments, the voltage output can be selectable via a user interface or otherwise defined by one or more outputs used by a user. In some examples, the mobile solar generator can output up to 250 amps at 120 VAC single-phase, up to 144 amps at 208 VAC single-phase, and up to 83 amps at 208 VAC three-phase. In the example of
In some examples, mobile solar generator 100 includes a plurality of outrigger 114 that can be deployed to engage the ground to, for example, stabilize the mobile solar generator 100 and/or prevent the mobile solar generator 100 from rolling on wheels. In the example of
As shown in the illustrated example of
As described, in some embodiments, outriggers can be moved between a stored configuration (such as shown in
In some embodiments, moving each of the plurality of outriggers from the stored outrigger configuration to the deployed outrigger configuration can include, for each of the plurality of outriggers, extending an arm of each the outrigger away from the housing and extending a leg of the outrigger downward such that a foot coupled to the bottom surface of the leg contacts a ground surface. Moving each of the plurality of outriggers can include adjusting a height of one or more of the plurality of outriggers in order to level the housing. In some embodiments, the leg(s) of one or more outriggers is extended so that one or more wheels are raised above the ground surface (see, e.g., arrow 115 showing a height that wheels are raised above ground surface 113 in
In some embodiments, outrigger motion can be controlled via hydraulics, for example, to extend outriggers from the housing and/or lower outrigger legs, for example, to raise one or more wheels of the mobile solar generator off of the ground. In some such examples, hydraulic cables can run through one or more housing channels and/or outrigger arms such that the hydraulic cables are hidden from view and protected from being pinched by moving parts. In some embodiments, multiple outriggers (e.g., two of four outriggers, four of four outriggers) can move (e.g., extend away from a housing and/or lower legs) simultaneously. In some examples, outriggers on a first side of a mobile solar generator are configured to move simultaneously and outriggers on a second side of the mobile solar generator are configured to move simultaneously, but at a different time as the outriggers on the first side of the mobile solar generator.
As described elsewhere herein, in some examples, solar array 116 of mobile solar generator 100 comprises can be moved between a stored solar array configuration (e.g., as in
The stored configuration and deployed configuration of the solar array can include a variety of dimensions. In some examples, the housing 118 can include a width and a length. The solar array 116 can have a dimension that is wider than the width of the housing 118 when in the deployed solar array configuration (e.g., as shown in
In a further embodiment, when the solar array 116 moves from the deployed solar array configuration to the stored solar array configuration, the solar array 116 can be configured to reduce in size (e.g., by folding, sliding, or other movements as described elsewhere herein) such that the width of the solar array 116 is less than or equal to the width of the housing 118 and is positioned such that the width of the solar array 116 when in the stored solar array configuration fits within the width of the housing 118. This sizing makes transportation of the mobile solar generator easier for a user and can make the device easier to maneuver during transportation.
The mobile solar generator can include ranges of dimensions. In an example embodiment, the width of the housing 118 can be between 8 feet and 9 feet. In some such examples, the width of the housing 118 can be approximately 8.5 feet. In some examples, the length of the housing is between 20 feet and 30 feet, and in some examples, the length of the housing is approximately 26 feet.
In some examples, the width of the solar array 116 in the deployed solar array configuration is between 18 feet and 24 feet and the width of the solar array 116 in the stored solar array configuration is between 8 feet and 9 feet. In some such examples, the width of the solar array 116 in the deployed solar array configuration is approximately 21 feet and the width of the solar array 116 in the stored solar array configuration is approximately 8.5 feet.
While example dimensions are provided, various sizes are possible. For instance, in some embodiments, the mobile solar generator 100 can be designed such that the width of the housing 118 is at or below a maximum width permissible for transportation without being designated a wide or oversized load.
As described elsewhere herein, in various examples, the solar array 116 can include features that allow solar panels 102 to move relative to one another and increase an area exposure to the sun when in the deployed solar array configuration and decrease such exposure when in a stored solar array configuration.
In some embodiments, an adjustable support pillar 112 with multi-axis pivot can adjust the solar array 116 in multiple directions. For example, the adjustable support pillar 112 can raise up and down as illustrated by line “A” while the multi-axis pivot can rotate about its axis as illustrated by line “B” and can tilt the solar array 116 up and down as illustrated by the line “C.” In some examples, the multi-axis pivot is an electromechanical assembly attached to the support pillar 112. In some examples, to deploy the mobile solar generator 100, the adjustable support pillar 112 can raise up (see line “A”) such that the solar array 116 has clearance to rotate about the adjustable support pillar 112 (see line “B”) without hitting other aspects of the mobile solar generator 100. In some examples, the adjustable support pillar 112 is configured to rotate relative to the housing 118 to adjust an orientation of the solar array 116.
In some embodiments, moving the solar array 116 from the deployed solar array configuration to the stored solar array configuration includes rotating the solar array 116 about an axis (e.g., as illustrated by “B” in
As illustrated in
In some embodiments, the outriggers 114 can include an electromechanical self-leveling feature to ensure the mobile solar generator 100 is as close to horizontal within a specified amount. The outriggers 114 can be deployed in a plurality of ways including completely manually, partially manually and partially automatically, or completely automatically. For example, the outriggers 114 can be deployed automatically when a user provides input to the mobile solar generator 100 via a user interface such as a touchscreen. The user interface can also include a graphical user interface on a display that can include guided and self-checking deployment of the mobile solar generator.
In addition to the outriggers 114, other portions of the mobile solar generator can be deployed completely manually, partially manually and partially automatically, or completely automatically. For example, after the outriggers 114 are deployed, a person can subsequently engage an auto-deploy feature for deploying the solar array 116 with the adjustable support pillar 112 with multi-axis pivot to a deployed configuration as illustrated in
In some examples, one or more persons can deploy the mobile solar generator 100 within a predetermined time period (e.g., in less than 15 minutes), using none, some, or all automated deployment. For instance, in one example, a user can hit a “deploy” button or other control on a human machine interface (e.g., touchscreen) and the mobile solar generator 100 can automatically deploy the outriggers 114, deploy the solar array from a stores solar array configuration to deployed solar array configuration, adjust the support pillar 112 and multi-axis pivot to orient the solar array 116 toward the sun, and optionally prepare any electronics needed to start generating and providing electrical power.
In some embodiments mobile solar generator includes a controller configured to control operation of one or more mobile solar generator 100 components. In various embodiments, a controller can include one or more processors, such as one or more digital signal processors, microprocessors, field-programmable gate arrays (FPGA), application-specific integrated circuits (ASICs), programmable logic, or other components, operating alone or in combination. In some embodiments, such a controller can include or otherwise be in communication with a memory containing instructions for causing the controller to carry out one or more processes, such as those described herein. In some examples, the mobile solar generator includes a user interface, User interface can include one or more inputs (e.g., a touchscreen, mouse, keyboard, etc.) by which a user can input one or more commands or requests to the controller and one or more outputs (e.g., a display, speaker, etc.) by which the controller can output information to be received by a user.
In some embodiments, the mobile solar generator includes a controller configured to control movement of the outriggers.
One or more electrical motors can have a variety of features. In some examples, one or more motors of the mobile solar generator can include a servo motor. For instance, in some embodiments, one or more servo motors can be configured to drive deployment of the solar array via the drive system 156. One or more servo motors can control the movement of the support pillar, the movement of the solar array relative to the support pillar, deployment of the solar array, or combinations thereof. In some such embodiments, the mobile solar generator can be raised, rotated, and/or unfolded using hydraulic cylinders driven by the servo motors.
Some current of the servo motor(s) can be monitored, e.g., using controller 150. For example, in some embodiments, a current monitor can output information to the controller regarding the current of the servo motor. The current monitor can include a current sensor integral with or separate from the servo motor. Such a sensor can be used to monitor a status of the mobile solar generator. For example, greater current drawn by the motor can indicate an increase in resistance to movement of the solar array, as an increase in resistance to movement can lead to increased motor torque and, as a result, an increased current draw.
Thus, in various examples, the amount of current drawn by the servo motor can be a function of the resistance to movement of the component(s) to be moved by the motor actuation. For example, a servo motor can be configured to raise the solar array via the support pillar, and the current drawn by the servo motor is a function of the resistance to raising the solar array. During operation (e.g., deploying solar array), the current drawn by the associated servo motor(s) can have an expected range, such as a maximum current value associated with a given operation (e.g., raising the solar array, expanding the solar array). Current values outside of the expected range (e.g., above a threshold value) can indicate excess resistance to the motion the servo motor is attempting to achieve (e.g., raising and/or expanding a solar array), such as due to a physical obstruction to the desired motion (e.g., a tree or other obstacle impeding the solar array from raising and/or expanding).
In some embodiments, the controller is configured to receive information regarding the current being drawn by one or more servo motors associated with movement of one or more components. The controller can be programmed with a predetermined current threshold for each of the servo motors. Different motors can have the same or different current thresholds associated therewith. The controller can be configured to compare the current associated with each motor to the corresponding threshold.
In some embodiments, when increased current greater than the predetermined current threshold is detected, the mobile solar generator can act to stop movement of at least the component facing the increased resistance, for example, by stopping providing power to the motor whose corresponding current exceeds a threshold. In some embodiments, if the current for any one motor exceeds at threshold, the controller is configured to stop motion of all motors associated with the motion in progress (e.g., deploying or collapsing the solar array, moving one or more outriggers, etc.).
In some embodiments, one or more motor(s) can act in combination with one or more hydraulic fluid lines to control movement of system components. For example, movement of the outriggers can be controlled via hydraulic fluid lines. The hydraulic fluid lines can be used to control movement of the outriggers during deployment and solar tracking. Various valves can be integrated into the hydraulic fluid lines, including, for example, one or more check valves. The check valves can be one-way valves and regulate fluid flow in the hydraulic lines such that flow is only permitted to flow one way through the valve(s) in the hydraulic fluid line.
In some such examples, if pressure is lost within a hydraulic fluid line having a check valve (e.g., due to a leak or other equipment failure), the check valves can mitigate the loss of pressure throughout the hydraulic line by preventing some hydraulic fluid from flowing backwards through the check valve to the location of a leak in the line. For example, if pressure decreases at a location in the hydraulic line, a check flow valve can maintain pressure at other locations along the hydraulic line. Lines carrying hydraulic fluid can include check valves. The check flow valve can prevent rearward flow of the hydraulic fluid at a location in the hydraulic line.
Maintaining pressure of the hydraulic fluid in the hydraulic line can prevent unwanted or uncontrolled movement or motion of components whose movement is controlled by the hydraulic line. For example, if the hydraulic line fails and pressure within the hydraulic line is not be maintained, uncontrolled movement and/or collapse of one or more components whose motion is controlled using such a hydraulic line, such as an outrigger or solar array. Unexpected or sudden movement of an outrigger or solar array can cause damage to the mobile solar generator, such as the outrigger(s) and/or solar array. Such movement can also cause injury or damage in the vicinity of the mobile solar generator. Check valves in the hydraulic lines help maintain pressure in hydraulic lines even in the event of fluid leaks or other equipment damage, and can prevent and/or reduce the risk of such an event.
A controller can be used to manipulate each of the outriggers into different configurations. For example, a controller can be configured to extend each of the four outriggers (e.g., 114a-c) away from the housing (e.g., 118) by extending the arm (e.g., 120a-c) of each of the outriggers (e.g., 114a-c) out of the respective channel in the housing (e.g., 118). This movement can facilitate the deployment of the outriggers.
Each of the plurality of outriggers can be configured to move between a stored outrigger configuration and a deployed outrigger configuration such as the configurations described herein. For example, in some embodiments, in the deployed outrigger configuration, the foot of the outrigger can extend to touch a ground surface, and in some cases, the controller can be configured to determine a level of the housing of the mobile solar generator and control the outriggers (e.g., by controlling one or more outrigger legs) to level the housing.
The housing can undergo changes in configuration throughout the deployment process. In some embodiments, moving each of the plurality of outriggers from the stored outrigger configuration to the deployed outrigger configuration can include raising the housing of the mobile solar generator such that each of the at least four wheels is raised off of the ground surface. In some examples, moving each of the plurality of outriggers from the stored outrigger configuration to the deployed outrigger configuration can include raising the housing of the mobile solar generator such that at least one of the plurality of wheels is raised off of the ground surface.
In some embodiments, each of the plurality of outriggers is further configured to move to an outrigger lift configuration in which the foot touches the ground surface, but no other component of the mobile solar generator touches the ground surface. In some embodiments, the deployed outrigger configuration comprises the outrigger lift configuration. In other embodiments, an outrigger lift configuration is different from the deployed outrigger configuration. For example, in some embodiments, the arm of each of the plurality of outriggers is configured to extend outward from the housing by a deployed distance in the deployed outrigger configuration, and in some such examples, moving the plurality of outriggers to the deployed outrigger configuration comprises extending the arm of each of the plurality of outriggers outward from the housing by the deployed distance. In some examples, the arm of each of the plurality of outriggers is configured to extend outward from the housing by a lift distance in the outrigger lift configuration, the lift distance being less than the deployed distance. In some such examples, moving the plurality of outriggers to the outrigger lift configuration comprises extending the arm of each of the plurality of outriggers outward from the housing by the lift distance.
In some examples, the controller is further configured to cause the plurality of outriggers to move to the outrigger lift configuration without adjusting the height of the adjustable support pillar or adjusting the orientation of the solar array relative to the adjustable support pillar.
In some embodiments, the outriggers can be used to bear some weight of the mobile solar generator, but not necessarily raise, for example, the wheels of the mobile solar generator fully off of the ground. For instance, in some embodiments, each of the plurality of outriggers is further configured to move to an outrigger partial lift configuration in which the foot of the outrigger touches the ground surface and wherein the plurality of wheels also touch the ground surface. In some such examples, plurality of wheels bear less of the weight of the mobile solar generator when the plurality of outriggers is in the outrigger partial lift configuration than when the plurality of outriggers is in the stored outrigger configuration.
As described, in some embodiments, moving each of the plurality of outriggers from the stored outrigger configuration to the deployed outrigger configuration can include leveling the housing via the plurality of outriggers. In some cases, the controller controls deployment of the outriggers such that the mobile solar generator can be self-leveling. In various examples, self-leveling movement can occur in different ways. For example, in some embodiments, the self-leveling movement can occur as each of the plurality of outriggers move simultaneously (e.g., wherein the legs of each of the outriggers move at the same time). In other embodiments, each of the legs of each of the outriggers can move individually and incrementally to self-level the housing.
Similar to the outriggers described above, in some embodiments, the controller can be configured to control deployment of the outriggers 114 and the solar array 116, for example, in response to a command received from a user interface. For instance, in some examples, the controller can be configured to cause each of the plurality of outriggers to move from the stored outrigger configuration to the deployed outrigger configuration in response to a first command received from the user interface. In some such examples, after causing each of the plurality of outriggers to move from the stored outrigger configuration to the deployed outrigger configuration, the controller can be configured to cause the solar array to move from the stored solar array configuration to the deployed solar array configuration in response to a second command received from the user interface. Thus, in some examples, the controller can be configured to cause each of the plurality of outriggers to move from the stored outrigger configuration to the deployed outrigger configuration before causing the solar array to move from the stored solar array configuration to the deployed solar array configuration.
The mobile solar generator can include additional components that interact with the outriggers. In some embodiments, the mobile solar generator can include a plurality of outrigger sensors corresponding to one of the plurality of outriggers. The plurality of outrigger sensors can be in communication with the controller and configured to output outrigger position information representative of a position of the arm and/or a position of the leg of the corresponding outrigger. Such sensor(s) can be used, for example, to determine a status of outriggers.
Additionally or alternatively, in some examples, the mobile solar generator can include a plurality of sensors in communication with the controller and configured to detect a position of the solar array when the solar array moves from the deployed solar array configuration to the stored solar array configuration. In some examples, the controller can be configured to output an alert (e.g., via a user interface) based on information provided by the plurality of sensors if the solar array deviates from an expected stored solar array configuration.
The controller can also include variety of safety checks. In some embodiments, the controller can be configured to, after causing each of the plurality of outriggers to move from the stored outrigger configuration to the deployed outrigger configuration and before causing the solar array to move from the stored solar array configuration to the deployed solar array configuration, present one or more safety checks via the user interface.
The safety checks can affect the deployment of the solar array. In some examples, the controller is configured to not cause the solar array to move from the stored solar array configuration to the deployed solar array configuration unless the controller receives, via the user interface, an acknowledgement of the one or more safety checks presented via the user interface. The controller can require acknowledgement of the one or more safety checks, for example, to allow a user to confirm, for example, that there is sufficient space to deploy the solar array and/or that there are no obstacles in the way that would interfere with deploying the solar array.
Multiple safety checks can be presented. For instance, in some embodiments, the one or more safety checks can include a plurality of safety checks. The controller can be configured to present each of the plurality of safety checks via the user interface. The controller can be configured to cause the solar array to move from the stored solar array configuration to the deployed solar array configuration only if the controller receives, via the user interface, a separate acknowledgement for each of the plurality of safety checks presented via the user interface.
In some examples, the controller can be configured to present safety checks in response to certain commands, such as received via the user interface.
If the safety check(s) are acknowledged (620), e.g., via a user input via the user interface, the process includes moving the outriggers to the deployed outrigger configuration 630. For example, the controller can be configured to cause each of the plurality of outriggers to move from the stored outrigger configuration to the deployed outrigger configuration in response to the first command only after receiving the acknowledgement of the one or more safety checks. In some examples, one or more additional safety checks can be performed within stages of an outrigger deployment process, for example, to ensure that foot pads are placed under the outrigger feet after extending outrigger arms but before lowering outrigger legs.
In some embodiments, after deploying the outriggers, the process includes receiving a second command from the user interface to move the solar array to the deployed solar array configuration 640, for example, via a user interface. After receiving the second command, the process includes presenting one or more safety checks 650, e.g., via the user interface. In some examples, such safety checks can ensure that there is sufficient clearance to deploy the solar array around the mobile solar generator and ensuring that wind speeds are below a threshold level. If the safety check(s) are acknowledged (660), e.g., via a user input via the user interface, the process includes moving the solar array to the deployed solar array configuration 670. For example, the controller can be configured to cause the solar array to move to the deployed solar array configuration in response to the second command only after receiving the acknowledgement of the one or more safety checks.
In some examples, in addition to one or more safety checks as described above, the controller only moves the solar array to the deployed solar array configuration if the outriggers have been first moved to the deployed outrigger configuration. In some examples, while various steps in
In various embodiments, similar safety checks are used when moving the outriggers from the deployed outrigger configuration to the stored outrigger configuration, and/or when moving the solar array from the deployed solar array configuration to the stored solar array configuration. In an example embodiment, the controller can be configured to cause the solar array to move from the deployed solar array configuration to the stored solar array configuration in response to a command received from the user interface. The controller can be configured to, after the solar array is in the stored solar array configuration, present one or more safety checks via the user interface and receive an acknowledgement of the presented one or more safety checks. The controller can be configured to, after receiving the acknowledgement, cause each of the plurality of outriggers to move from the deployed outrigger configuration to the stored outrigger configuration.
In some examples, one or more aspects of the deployment of the outriggers and/or solar array are performed automatically, for example, by the controller (e.g., 150) interfacing with an outrigger drive system (e.g., 154) and/or a solar array drive system (e.g., 156). For instance, in some embodiments, moving each of the plurality of outriggers from the stored outrigger configuration to the deployed outrigger configuration and the moving the solar array from the stored solar array configuration to the deployed solar array configuration include a plurality of automated steps. In some examples, the plurality of automated steps can include at least two automated steps separated by a confirmation step. The confirmation step can include outputting a safety check after a first of the at least two automated steps. In some examples, the mobile solar generator does not proceed to the second of the at least two automated steps until receiving an acknowledgement of the safety check. In some examples, the aggregate time it takes to complete the plurality of automated steps associated with moving each of the plurality of outriggers to the deployed outrigger configuration and moving the solar array to the deployed solar array configuration is under 15 minutes. In some such examples, the aggregate time it takes to complete the plurality of automated steps can be under 10 minutes.
Because some example processes require manual interaction (e.g., acknowledging one or more safety checks via a user interface), the total deployment time may depend on the responsiveness of a user acknowledging the safety checks. However, the automated steps independent of a time spent waiting for a user to acknowledge the safety checks can be under 15 minutes, and in some examples, under 10 minutes.
Continuing with the process of
In some embodiments, a process such as that shown in
In addition or as an alternative to the one or more safety checks discussed above, in some examples, a mobile solar generator includes one or more alarms (e.g., lights, bells, speakers, etc.) to alert those nearby of upcoming movement of one or more aspects of the mobile solar generator. For instance, in some examples, a mobile solar generator includes one or more lights that can illuminate and/or speakers that can output a sound prior to and/or while outriggers and/or solar array is moved between configurations (e.g., between stored and deployed configurations).
As described elsewhere herein, in some embodiments, solar array (e.g., 116 in
Movement of the solar array can be facilitated using a variety of components.
In some examples, the solar array drive system 756 can include one or more electromechanical components. In some embodiments, the solar array drive system 756 can include one or more hydraulic actuators, electric motors, or other types of motors or actuators configured to cause movement of the solar array. In some examples, solar array drive system 756 includes one or more electric motors configured to cause rotation of the solar array about one or more axes (e.g., along lines B and C in
The solar array drive system 756 can be configured to move the solar array (e.g., 116) about each of the at least two axes of rotation relative to the adjustable support pillar (e.g., 112) (e.g., as shown by “B” and “C” in
Because the mobile solar generator is mobile, the position of the sun relative to the generator can change depending on the location of the generator. For example, as the generator is moved north or south, the elevation angle of the sun relative to the generator can be different for a given time of a given day. Additionally, the facing direction of the generator can be different each time the generator is used, for example, when the generator is brought to a location for operation. Thus, in some cases, the global position and/or facing direction of the mobile solar generator may vary from use to use.
Accordingly, in various embodiments, the generator can include components and features to accommodate for use in various locations. In some embodiments, a controller 750 can be configured to cause the solar array drive system 756 to move a solar array (e.g., 116) to track the sun. In some such embodiments, the controller 750 can be configured to determine a motion path for the solar array to track the sun and/or periodically calculate a new facing direction in order to move the solar array to face the sun.
In some embodiments, mobile solar generator can include a compass 710, such as a digital compass, and a global positioning system (GPS) 700. The controller 750 can be configured to receive position information from the GPS 700, receive direction information from the compass 710, and determine the motion path for the solar array to track the sun based on the position information and the direction information.
In some embodiments, the mobile solar generator can include one or more time-telling components for tracking the sun. For instance, in some embodiments, the mobile solar generator can include a clock 730 and a calendar 720. The controller 750 can be configured to receive time-of-day information from the clock 730, receive date information from the calendar 720, and use the time-of-day information and date information when tracking the sun. In some embodiments, the controller is configured to periodically update an orientation of the solar array to move the solar array, for example, along the motion path based on the time-of-day information and the date information. In some examples, the time-telling components can be used in combination with the positioning components to track the sun.
In some embodiments, the controller 750 can be configured to receive information from one or more components, such as the GPS 700, compass 710, calendar 720, and/or clock 730 and cause the solar array drive system to move the solar array based on the received information. In some examples, controller 750 can be configured to perform functions described with respect to controller 150 in
In some examples, some or all of such information can be used to determine movement of the solar array to track the sun. In some examples, a method related to such movement can include tilting the solar array about a first axis of rotation relative to the adjustable support pillar (e.g., as shown in “C” in
In some examples, the method can include using location information to determine the movement of the solar array. In some embodiments, the method includes determining a coordinate position of the mobile solar generator based on information received from a global positioning system (GPS). In some embodiments, the method can include determining a motion path for the solar array to track motion of the sun based on the facing direction and the coordinate position. The motion path can include a plurality of orientations of the solar array. For example, in some embodiments, a GPS position and facing direction provide information such that a relative position of the sun can be predicted for a given time and date.
The method can include using time information, such as the date and/or time of day to determine the movement of the solar array. In some embodiments, the method can include determining a date based on information received from a calendar 720. In some examples, determining the motion path for the solar array to track the sun is further based on the date. In some examples, the motion path comprises a relationship between a time of day and a relative position of the sun based on a date, coordinate location, and facing direction.
In some cases, moving the solar array can be based on the time of day. In some embodiments, the method can include determining a time of day based on information received from a clock 730. The method can include moving the solar array to a predetermined orientation along the motion path based on the time of day. In some examples, time of day and/or date information can be used in combination with the location information.
The method can include moving the solar array in various orientations. In some embodiments, the method can include adjusting an orientation of the solar array to each of the plurality of orientations along the motion path by tilting the solar array about the first axis of rotation relative to the adjustable support pillar and rotating the solar array about the second axis of rotation relative to the adjustable support pillar. The plurality of orientations can include the first orientation and the second orientation.
In the example of
In some embodiments, positioning the solar array in an orientation comprises positioning the solar array in an orientation based on a predetermined motion path.
The process of
In some such examples, a controller can be configured to periodically determine a desired solar array orientation based on a calculated motion path and update the orientation of the array to face a determined orientation. In some embodiments, for instance, when updating a solar array orientation according to a calculated motion path, determining a time of day (e.g., as in step 910), can include receiving information from a clock representing a time of day. Additionally or alternatively, in some examples, determining a time of day includes determining a relative time of day compared to a previously determined time of day. For instance, in some examples, a controller can determine that, since a previous adjusting of a solar array to face a determined orientation, a predetermined amount of time has passed (e.g., the predetermined time of step 940), and can use such information to determine an updated solar array orientation.
In some examples, a desired orientation can be calculated each time the orientation is to be updated.
The process of
In various embodiments, as described herein, a controller can be configured to adjust a solar array orientation via a solar array drive system by which the controller can adjust the solar array to face a desired orientation.
In some cases, moving the solar array to track the position of the sun increases an amount of power that can be generated by the solar array compared to a stationary array. However, the process of moving the array can consume energy. In some examples, adjusting an orientation of the solar array in the method can occur periodically, for example, a predetermined frequency. In some embodiments, adjusting the orientation of the solar array to each of a plurality of orientations along a determined motion path can include adjusting the orientation of the solar array at a predetermined frequency. In some examples, adjusting the orientation of the solar array at a predetermined frequency can include adjusting the orientation of the solar array at a rate of between once every 10 minutes and once every 60 minutes.
In some embodiments, periodic update of the orientation of the solar array comprises periodically determining a solar array orientation, for example, such as freshly calculating a preferred solar array orientation at predetermined intervals. In some embodiments of the mobile solar generator 100, periodically updating the orientation of the solar array 116 can include, at predetermined intervals, determining an updated preferred orientation of the solar array 116 based on the position information, the direction information, the time-of-day information, and the date information, and adjusting the orientation of the solar array 116 to the updated preferred orientation via the solar array drive system (e.g., 756). In some embodiments, the controller can be configured to determine and move the solar array to an updated orientation at a rate of between once every 10 minutes and once every 60 minutes.
Additionally or alternatively, in some cases, added power generation benefits gained from tracking the sun diminish at times when the sun is low on the horizon, such as during sunrise or sunset. In some embodiments, the controller of the mobile solar generator can be configured to determine if the time of day (e.g., based on information received from a clock) is within a predetermined window of time. In some such embodiments, the controller is configured to periodically update the orientation of the solar array (e.g., by freshly calculating a new desired orientation or moving the array along a predetermined motion path) only if the time of day is within the predetermined window of time.
For example, in some embodiments, the process of
As described elsewhere herein, in some embodiments, updating the orientation of the solar array can occur at different times and in varying frequencies. In the process of
As described, in some embodiments, the mobile solar generator uses information from various components, such as a compass, GPS, clock, and calendar, to determine an orientation of the solar array to track the sun. In some cases, the mobile solar generator does not use irradiance as an input to solar tracking, as moving the solar array based on irradiance information can require additional energy consumption in order to move the solar array through enough candidate orientations to determine a preferred orientation based on the irradiance.
As described elsewhere herein, in some embodiments, mobile solar generator 100 includes one or more batteries that can store power generated by the solar panels 102 of the solar array 116. In some examples, such one or more batteries can be stored in one or more battery compartments of the mobile solar generator, for example, within the housing of the mobile solar generator. Battery compartments can include one or more batteries included therein.
Any variety of batteries can be used. In some examples, batteries comprise lithium batteries. In some examples, the batteries are LiFePO4 batteries. In some embodiments, the one or more batteries are configured to produce an output voltage of between 30 V and 60 V. In some such embodiments, the one or more batteries are configured to produce an output voltage of 48 V. Other possible voltage arrangements are possible. For example, an output voltage can be up to 1000V or 2000 V. In some embodiments, an output voltage can be selected to be within an operating voltage range of one or more system components, such as one or more inverters. In some embodiments, the output voltage comprises a voltage made up of a plurality of batteries, each having a lower voltage than the output voltage, arranged in series to achieve an output voltage. In various embodiments, individual batteries can be arranged in series, parallel, or combinations of series and parallel. In various embodiments, the batteries have a total charge capacity of between 60 kWh and 180 kWh.
In some examples, one or more batteries can be within the housing of the mobile solar generator, for example, in an enclosure that is easily accessible for permitting access to the enclosure, for example, for replacing or otherwise servicing the one or more batteries. In some examples, the one or more batteries are enclosed in an environmentally controlled compartment that can regulate environmental conditions for the batteries (e.g., temperature, humidity). The mobile solar generator can also include a fire suppression system for the batteries which can be integrated into a battery compartment.
In some embodiments, a battery compartment is accessible from a bottom surface of a housing of a mobile solar generator. In some such examples, for each of one or more battery compartments, the mobile solar generator includes one or more battery compartment access panels configured to cover the battery compartment from outside of the housing. Battery compartment access panels can be movable to permit access from the outside of the housing into the battery compartment. In some examples, the battery compartment access panels are positioned on a bottom side of the housing, and a corresponding battery compartment is accessible from a bottom side of the housing when the battery compartment access panels are removed.
As described, in some embodiments, a mobile solar generator includes an environmentally controlled compartment.
The battery compartment 1140 of
In some embodiments, a mobile solar generator includes one or more chillers 1149 proximate a battery compartment 1140 configured to condition air for flowing through the battery compartment. Chiller 1149 can include, for example, a refrigerant circuit configured to condition air. In some examples, a refrigerant circuit is part of a phase-change refrigeration system. In the illustrated example, fans 1148 are configured to blow air conditioned by chiller 1149 into the battery compartment 1140. In some examples, a liquid cooling system can be used.
In some embodiments, a mobile solar generator can include a plurality of batteries stored in one or more battery compartments.
In the illustrated examples, chassis 1260 supports chiller 1249, which can be used to provide conditioned air to control the climate of one or more battery compartments, for example, via one or more fans.
In some examples, a controller of the mobile solar generator can be configured to control the climate within a battery compartment.
The controller can be configured to determine a temperature of the battery compartment and selectively heat or cool the battery compartment via heater 1346 or cooler 1348 in order to maintain the battery compartment within a predetermined temperature range. For example, in some embodiments, the controller 1350 can compare the temperature to a lower temperature threshold and, if the temperature is below the lower temperature threshold, activate the heater 1346 to increase the temperature of the battery compartment. Similarly, in some embodiments, the controller 1350 can compare the temperature to an upper temperature threshold and, if the temperature is above the upper temperature threshold, activate the cooler 1348 (e.g., a chiller, a fan, or both) to decrease the temperature of the battery compartment. In some cases, maintaining batteries within a predetermined range of temperatures can allow the batteries to operate at a higher efficiency and/or charge storage capacity compared to similar batteries outside of the predetermined range of temperatures.
In some examples, a mobile solar generator further includes supplemental batteries which can be used to power peripheral lighting or accessories. For instance, the mobile solar generator can include peripheral lights which enable users to, for example, deploy and/or service the mobile solar generator in dark environments. In some examples, supplemental batteries can be used to power battery compartment climate control systems, such as powering one or more heaters, chillers, fans, or the like. In some embodiments, the mobile solar generator includes a plurality of lights supported by the housing of the mobile solar generator, and in some such examples, the controller is configured to control illumination of the plurality of lights. In some examples, the controller can cause such lights to illuminate in response to a user input. Additionally or alternatively, controller can cause lights to illuminate automatically, for example, due to an alarm or warning.
As described herein, in some examples, one or more inverters are stored in one or more inverter compartments. In some such embodiments, one or more inverter compartments can be climate controlled in order to maintain a climate within the inverter compartment, such as maintaining a temperature within the inverter compartment within a predetermined temperature range. In some examples, the components for heating, cooling, measuring, and controlling a temperature of an inverter compartment can be similar to those described above with respect to the battery compartment climate control.
For instance, the example of
The controller can be configured to determine a temperature of the inverter compartment and selectively heat or cool the inverter compartment via heater 1376 or cooler 1378 in order to maintain the inverter compartment within a predetermined temperature range. For example, in some embodiments, the controller 1350 can compare the temperature to a lower temperature threshold and, if the temperature is below the lower temperature threshold, activate the heater 1376 to increase the temperature of the inverter compartment 1307. Similarly, in some embodiments, the controller 1350 can compare the temperature to an upper temperature threshold and, if the temperature is above the upper temperature threshold, activate the cooler 1378 (e.g., a chiller, a fan, or both) to decrease the temperature of the inverter compartment. In some cases, maintaining inverter within a predetermined range of temperatures can prevent undesired inverter operation at extreme temperatures.
In some examples, an inverter climate control system can share one or more components with a battery compartment climate control system. For example, in some embodiments, a chiller (e.g., chiller 149) can be configured to condition air (e.g., via a refrigerant circuit) that can be used to cool both a battery compartment and an inverter compartment. In other examples, the inverter climate control system and a battery climate control system can use separate components for heating and/or cooling. In some cases, even if separate heating and/or cooling components are used, a common controller (e.g., 1350) can be used to control the climate control system for both the battery compartment(s) and inverter compartment(s). In other examples, each can include a separate climate control system controller.
In some examples, controller 1350 can be configured to perform functions described with respect to controller 150 in
In some embodiments, electrical power can be distributed to and from various components of the mobile solar generator.
A power distribution interface 1475 is in communication with various such components and can be configured to facilitate providing electrical power from one component to another. In some examples, power distribution interface comprises a series of switches or other such elements configured to control electrical communication between components. In some embodiments, controller 1450 is configured to control the power distribution interface in order to selectively provide electrical power from one component to another. Additionally or alternatively, in some examples, the functionality of the power distribution interface can be performed via one or more system components, such as one or more inverters 1405.
In some embodiments, a mobile solar generator includes a solar charger 1445 configured to provide charge to the one or more batteries 1441. In some examples, the solar charger 1445 is configured to perform maximum power point tracking (MPPT) to control power output from the solar array 1416 in order to draw a maximum level of power from the solar array 1416. In some examples, controller 1450 is configured to control operation of the solar charger, for example, to control when power is being provided from the solar array 1416 to the one or more batteries 1441, for example, via the solar charger 1445. In some such examples, the solar array 1416 is not connected to the power distribution interface 1475, but instead only provides power to the one or more batteries 1441 through the solar charger 1445.
In some example implementations, controller 1450 can be configured to cause the generator 1408 to provide electrical energy to one or more batteries 1441, for example, to charge batteries 1441. Additionally or alternatively, controller 1450 can be configured to cause the generator to provide electrical energy directly to a power output 1490, for example, to a load connected thereto.
The example of
In some embodiments, the controller 1450 is configured to determine status information regarding one or more mobile solar generator components. In various examples, controller can determine an amount of power being generated at the solar array 1416, a state of charge of the one or more batteries 1441 (e.g., an aggregate state of charge of a plurality of batteries and/or an individual state of charge of each of a plurality of batteries), an amount of power being drawn at power output 1490, an amount of power available at power input 1480, and/or other status information. In some such examples, controller 1450 is configured to output status information via the user interface 1452, such as via a display.
In some examples, the controller 1450 can control power distribution based on determined information regarding one or more components. For instance, in an example embodiment, the controller 1450 is configured to determine a state of charge of one or more batteries 1441, compare the determined state of charge to a threshold state of charge, and, if the state of charge is below the threshold state of charge, cause the generator 1408 to provide electrical power to the one or more batteries 1441. Thus, in some embodiments, the generator 1408 can be used to charge the one or more batteries 1441 if the state of charge of the one or more batteries 1441 is below a threshold. In some cases, the threshold can be set and/or adjusted by a user via user interface 1452.
In some examples, the controller 1450 can prioritize charging the one or more batteries 1441 via the solar array 1416, for example, rather than generator 1408. For example, in some embodiments, the controller 1450 is further configured to determine an amount of energy provided to the one or more batteries 1441 from the solar array 1416, and if the state of charge is below the threshold state of charge and the amount of energy provided to the one or more batteries 1441 from the solar array 1416 is below a threshold amount of energy, then cause the generator 1408 to provide electrical energy to the one or more batteries 1441.
Similar to as described elsewhere herein, in some examples, controller 1450 can be configured to perform functions described with respect to controller 150 in
However, if the state of charge of the one or more batteries is below the threshold state of charge, the process proceeds to determining an amount of power provided by the solar array to the one or more batteries 1530 and determining if the amount of power is above a threshold amount of power 1540. If so, then the process repeats by continuing to provide electrical power to the one or more batteries from the solar array 1500 and monitoring the state of charge of the one or more batteries (e.g., via steps 1510 and 1520).
However, if the amount of power provided by the solar array to the one or more batteries is below the threshold amount of power, the process includes providing electrical power from a generator to the one or more batteries 1550. For example, the generator can be used to make sure the one or more batteries stay above a threshold minimum state of charge in order to maintain battery health and/or ensure that the one or more batteries contain enough charge to power a load as desired.
In some examples, the process of
As noted above, in some examples, in some embodiments, a threshold state of charge can be an aggregate state of charge, for example, corresponding to a total state of charge of a plurality of batteries. Additionally or alternatively, in some embodiments, a threshold state of charge can be an individual state of charge threshold applied individually to each of a plurality of batteries.
As shown in the illustrated example of
In some embodiments, the external power input 1480 and/or power output 1490 can be connected to an electric grid, such as a large scale grid and/or a microgrid. The mobile solar generator can provide energy to and/or draw energy from such an electric grid. Additionally or alternatively, multiple solar generators can be used in combination with one another. Multiple mobile solar generators can be coupled to one another, for example, to form a microgrid. Such a configuration can increase the power capacity and/or power output of the mobile solar generator(s). In some embodiments, multiple mobile solar generators can be connected in parallel to provide a greater maximum current output compared to a single mobile solar generator. Additionally or alternatively, in some examples, two or more solar generators can be cascaded.
In some embodiments, a plurality of mobile solar generators can be connected in parallel to a central hub such that the mobile solar generators each provide power to the central hub. The central hub can provide power to one or more loads using power received from the plurality of mobile solar generators. In some embodiments, each of the plurality of mobile solar generators can be in communication with at least one other mobile solar generator of the plurality of mobile solar generators (e.g., via a wire) in order so synchronize phase information between mobile solar generators outputting AC power.
In some embodiments, mobile solar generator includes a series of collapsed or folded solar panels supported by a housing. The mobile solar generator also includes outriggers which retract into the housing and can further include additional electrical components such as batteries, inverters, load connections, circuit breakers, switches, etc.
In some examples mobile solar generator 1600 includes one or more camlocks, one or more twist lock connectors, and one or more NEMA connectors. In some examples, mobile solar generator includes multiple types of connectors, such as 5-30R NEMA connectors and 5-20R NEMA connectors. In some examples, different connectors are configured for outputting different power outputs, such as single phase or three phase power. Additionally or alternatively, different connectors can be rated for, for example, different amounts of electrical current. For instance, an example mobile solar generator includes a set of female camlocks configured to output 120 or 208 VAC in three phases up to 100 amps, one or more NEMA L21-20R twist lock connectors configured to output 120 or 208 VAC in three phases up to 20 amps, one or more CS6369 twist lock connectors configured to output 120 or 208 VAC in a single phase up to 50 amps, one or more NEMA 5-30R connectors configured to output 120 VAC in a single phase up to 30 amps, and one or more 5-20R connectors configured to output 120 VAC in a single phase up to 20 amps.
In some examples, the plugs 1680 of mobile solar generator can include one or more electrical inputs in addition to one or more electrical outputs. The one or more electrical inputs can be used to charge the batteries of the mobile solar generator using an external source without using the integrated power generation of the mobile solar generator (e.g., solar panels, generator). For instance, in some embodiments, one or more of the camlock connections can connect to an external power source, such as a shore power source, and receive electrical power therefrom. Such received electrical power can be provided to one or more batteries to charge such batteries.
In some embodiments, a mobile solar generator 1600 includes an openable hatch 1682 connected to the housing proximate a cable interface location where one or more cables can be connected to the mobile solar generator, such as at one or more camlock connections or other interfaces (e.g., proximate plugs 1680). In some embodiments, the openable hatch can be closed to prevent access to the cable interface location and can be opened to permit convenient access to cable interface location. In some examples, the mobile solar generator comprises a sensor configured to sense whether the openable hatch 1682 is open or closed. In some such examples, a controller in communication with the sensor and is configured to determine whether the openable hatch is opened or closed. In some such examples, the controller is configured to prevent transmission of electrical energy from one or more plugs 1680 unless the openable hatch is in the closed position. This can prevent a person or other object from easily accessing or accidentally contacting powered plugs and reduce a risk of shock, short circuits between plugs, or other undesired consequences. As described elsewhere herein, in some embodiments, a mobile solar generator controller can be configured to control power distribution between various mobile solar generator components, and in some examples, can prevent power output to one or more plugs if the hatch is in an open position.
The openable hatch 1682 of the mobile solar generator 1600 can include at least one lock. In some embodiments, the lock can be a solenoid lock. The lock can be configured such that, when one or more connectors behind a closed hatch are energized, the solenoid can trigger a door lock and disable access to the contents behind the openable hatch 1682. In some such embodiments, the openable hatch 1482 combined with a lock (e.g., a solenoid lock) can prevent a user from accessing the energized connectors and/or cables, which can help prevent injury to a user or damage to the cables and/or connectors. The solenoid can be configured to disable the door lock when the connectors are not energized, thereby allowing a user to access the contents behind the openable hatch 1482.
The mobile solar generator 1600 further includes a user interface 1652. The illustrated example includes a display 1653, which can display information about the mobile solar generator. In some examples, display 1653 can display information such as power being generated, battery charge level (e.g., of one and/or a plurality of batteries), the load level, and other information. In some examples, a controller is in communication with the user interface 1652 and is configured to determine such information and output such information via display 1653. In some embodiments, display 1653 comprise a touchscreen that can receive a user input. Additionally or alternatively, in some examples, interface 1652 includes one or more buttons, switches, knobs, or other components by which a user can input information. A mobile solar generator controller can receive inputs via interface 1652, such as, for example, a command to deploy a solar array or outriggers, acknowledgement of one or more safety checks, etc.
In some examples, a mobile solar generator can include one or more sensors, for example, positioned on a sensor tower supported by the mobile solar generator. Returning to
In some embodiments, the sensor tower 170 can be tiltable relative to the solar array 116. In some such examples, the controller can be configured to control the tilt of the sensor tower 170 relative to the solar array 116.
As described elsewhere herein, in some embodiments, the solar array 116 can be tiltable relative to the adjustable support pillar 112 (e.g., as shown by “C” in
The sensor tower can help protect the mobile solar generator against various elements (e.g., wind), which can cause damage to the solar array if not mitigated. In some the sensor tower can be adjusted so that it is unobstructed by the solar array, for example, so that the solar array 116 does not block wind that would otherwise be sensed by a wind sensor on sensor tower. In some embodiments, the sensor tower 170 can remain unobstructed by the solar array 116 before, during, and after any movement by the solar array 116, for example, by extending upward from the solar array 116 and remaining perpendicular to a level plane. By being able to sense the various conditions around the solar array, the mobile solar generator can undergo the various protective steps described herein to mitigate against the elements.
The sensor tower may be positionable in a variety of configurations. The sensor tower 170 can be configured to move between a stored sensor tower configuration (e.g., folded down to extend in a direction parallel with the surface of one or more solar panels of solar array 116) and a deployed sensor tower configuration (e.g., extending upward from the solar array 116 and remaining perpendicular to a level plane). In some examples, the controller is configured to control movement of the sensor tower 170 to move the sensor tower 170 between the stored sensor tower configuration and the deployed sensor tower configuration and receive wind information from the wind sensor 172 when the sensor tower 170 is in the deployed sensor tower configuration.
In some embodiments, a mobile solar generator 100 can include a housing 118, an adjustable support pillar 112 coupled to the housing 118 and configured to extend upward from the housing 118, a solar array 116 comprising one or more solar panels 102, and a wind sensor 172. In some examples, mobile solar generator 100 includes a controller in communication with the wind sensor 172. The solar array 116 can be supported by the adjustable support pillar 112 such that a height of the solar array 116 is adjustable via the adjustable support pillar 112 (e.g., as represented by “A” in
As described herein, a mobile solar generator controller can perform a variety of functions. In some examples, the controller can be configured to control movement of the solar array 116 to move the solar array between a stored solar array configuration and a deployed solar array configuration. The controller can receive wind information from the wind sensor 172 representative of at least a wind strength, and, if the solar array 116 is in the deployed solar array configuration and the wind information satisfies a predetermined threshold (e.g., is above a threshold wind strength), the controller can move the solar array 116 into a safe mode configuration different from the deployed solar array configuration. For example, in some embodiments, the controller can move the solar array 116 into the safe mode configuration if the wind strength is above a wind strength threshold, which can prevent strong winds from damaging a deployed solar array and/or other components of the mobile solar generator 100 due to the wind catching the deployed solar array 116.
In some examples, a controller can receive and act on wind information if the solar array is in the stored solar array configuration. For instance, in some examples, if the solar array 116 is in the stored solar array configuration and the wind information satisfies a first predetermined threshold (e.g., is above a threshold wind strength), the controller can maintain the solar array 116 in the stored solar array configuration. Additionally or alternatively, in some cases, a predetermined threshold can include a condition under which it is safe to deploy a solar array. For instance, in some embodiments, the controller can be configured to, if the solar array 116 is in the stored solar array configuration and the wind information satisfies a predetermined threshold (e.g., is below a threshold wind strength), the controller can move the solar array 116 into the deployed solar array configuration.
In some embodiments, a safe mode configuration can include a configuration between the deployed solar array configuration and the stored solar array configuration. For instance, in some embodiments, the deployed solar array configuration can include the solar array being raised above the housing to a deployed height via the adjustable support pillar. In some examples, the deployed height corresponds to the top of the adjustable support pillar 112 being between approximately 12 feet and 15 feet above the ground. The controller can be configured to move the solar array 116 into the safe mode configuration by adjusting the adjustable support pillar 112 to lower the solar array 116 to a safe mode height.
Additionally or alternatively, in some examples, moving the solar array 116 to a safe mode configuration comprises moving one or more solar panels relative to one or more other solar panels. For instance, as described herein, in some examples, mobile solar generator 100 can include a solar array 116 comprising a plurality of solar panels 102. In some embodiments, the controller is configured to move the solar array 116 into the safe mode configuration by moving the solar array 116 into a closed solar array configuration. In some examples, the closed solar array configuration includes the stored solar array configuration. In some such examples, moving the solar array into the safe mode configuration comprises moving the solar array to the stored solar array configuration. In other examples, the closed solar array configuration is different from the stored solar array configuration. In some examples, the stored solar array configuration includes the closed solar array configuration, but the closed solar array configuration does not necessarily require the solar array to be in the stored solar array configuration. For instance, in an example, in moving to the safe mode configuration, the solar array tilts to be level with the ground and then folds or otherwise reduces in size such as described elsewhere herein. In some cases, in moving to the safe mode configuration, the adjustable support pillar 112 remains at the deployed height.
For instance, in some examples, in a stored solar array configuration, fewer solar panels are exposed compared to the deployed solar array configuration. With reference to
As described, in some examples, moving the solar array to the safe mode configuration comprises moving the solar array to the stored solar array configuration. In other examples, the safe mode configuration is different from the stored solar array configuration. For instance, in some examples, in the safe mode configuration, the controller can adjust the solar array so that fewer solar panels are exposed compared to the deployed solar array configuration, such as the differences in the exposed solar panels 102 between
In some examples, moving the solar array to the safe mode configuration does not include lowering the solar array via the adjustable support pillar. Instead, in some examples, the solar array 116 is reduced in size so that fewer solar panels are exposed compared to the deployed solar array configuration, and the total area of the solar array is less than in the deployed solar array configuration. However, the safe mode configuration does not necessarily require lowering the solar array toward the housing via an adjustable support pillar. In some examples, moving the solar array to the safe mode configuration comprises lowering the solar array via the adjustable support pillar to a height between the stored solar array configuration and the deployed solar array configuration.
Various configurations are possible for changing a solar array size, for example, to move the solar array between a stored solar array configuration, a deployed solar array configuration, and, in some embodiments, a separate safe mode configuration, such as described elsewhere herein.
In some examples, moving the solar array into the safe mode configuration (e.g., the stored solar array configuration or a separate safe mode configuration) involves moving the solar array (e.g., 116) but not moving any already-deployed outriggers (e.g., 114). The outriggers (e.g., 114) can maintain a steady base for the mobile solar generator during windy conditions.
As described, in some embodiments, a mobile solar generator controller can act in response to wind information, such as wind speed detected via a wind sensor. In some embodiments, the controller can receive wind information from the wind sensor 172 representative of at least a wind strength, and, if the solar array 116 is in the deployed solar array configuration and the wind information satisfies a predetermined threshold (e.g., is above a threshold wind strength), the controller can move the solar array 116 into a safe mode configuration different from the deployed solar array configuration.
In some examples wherein the safe mode configuration is different from the stored solar array configuration, the controller is configured to compare the wind information to a second predetermined threshold corresponding to a second wind speed, the second wind speed being greater than the first wind speed. In some such examples, if the wind information satisfies the second predetermined threshold, the controller is configured to move the solar array into the stored solar array configuration.
In the illustrated embodiment, if the wind information does exceed a first threshold (1730), the mobile solar generator can determine if the wind information exceeds a second threshold (1750), for example, if the wind speed exceeds a second wind speed threshold greater than the first windspeed threshold. If so, the mobile solar generator can move the solar array to the stored solar array configuration (1770). In some examples, if the wind information does not exceed the second threshold (1750), then the mobile solar generator can move the solar array to a safe mode configuration (1760). As described herein, in some examples, the safe mode configuration is different from the stored solar array configuration. In other examples, wherein the safe mod configuration is the same as the stored solar array configuration, if the wind information exceeds the first threshold (1730), the mobile solar generator can move the solar array to the safe mode configuration that is the stored solar array configuration.
In some examples, whether the solar array is moved to the stored solar array configuration or a separate safe mode configuration in response to wind information satisfying one or more predetermined thresholds, the mobile solar generator can be configured to output an alert (1780), for example, to warn people within the vicinity of the mobile solar generator of automated movement of one or more mobile solar generator aspects. Such alerts can include playing one or more sounds, such as via one or more speakers, and/or illuminating one or more lights of the mobile solar generator. Additionally or alternatively, in some examples, outputting an alert comprises sending one or more alerts to a remote location, such as via a network, for example, to inform a remotely located user that the solar array configuration has changed. I some examples, after moving the solar array into a stored solar array configuration or a separate safe mode configuration, the mobile solar generator ceases tracking of the position of the sun (1790).
The solar controller can act in response to a variety of wind speeds. In some embodiments, a first threshold is approximately 50 miles per hour, and if the wind speed exceeds 50 miles per hour, the mobile solar generator moves the solar array into the safe mode configuration. In some examples, such safe mode configuration is the stored solar array configuration, such that if the windspeed is greater than 50 miles per hour, the mobile solar generator moves the solar array to the stored solar array configuration.
In some embodiments, if the windspeed is above a second, greater threshold (e.g., 75 miles per hour), the mobile solar generator moves solar array into the stored solar array configuration. Thus, in some examples, a mobile solar generator controller can be configured to maintain the solar array in the deployed solar array configuration if the windspeed is below 50 miles per hour. In some embodiments, the controller moves the solar array to a safe mode configuration different from the stored solar array configuration if the windspeed is between 50 miles per hour and the second, greater threshold speed, and in some embodiments, the controller moves the solar array to the stored solar array configuration if the windspeed is above the greater threshold speed.
In some examples, the mobile solar generator can continue to monitor wind speed after moving the mobile solar generator to the stored solar array configuration or safe mode configuration, and in some such examples, move the solar array to the deployed solar array configuration or the safe mode configuration. For example, in some embodiments, the controller can be further configured to, if the solar array is in the stored solar array configuration and the wind information does not satisfy a first predetermined threshold (e.g., falling below a first threshold windspeed), keep the solar array in the stored solar array configuration. In some embodiments of the mobile solar generator, the controller can be further configured to, if the solar array is in the stored solar array configuration and the wind information does not satisfy the first predetermined threshold (e.g., does not fall below the first threshold windspeed) but does satisfy a second predetermined threshold (e.g., does fall below a second threshold windspeed, higher than the first), move the solar array into a safe mode configuration different from the deployed solar array configuration.
In some embodiments, the controller can be further configured to, if the solar array is moving from the stored solar array configuration to the deployed solar array configuration and the wind information satisfies a predetermined threshold, stop movement of the solar array. In some embodiments, the controller can be further configured to, if the solar array is moving from the stored solar array configuration to the deployed solar array configuration and the wind information satisfies the predetermined threshold, return the solar array to the stored solar array configuration.
The position of the solar array can affect the solar tracking capabilities of the mobile solar generator. In some embodiments, the controller can be further configured to move the solar array to track the position of the sun when the solar array is in the deployed solar array configuration. In some embodiments, the controller does not move the solar array to track the position of the sun when the solar array is in the safe mode configuration.
As described, in some embodiments, mobile solar generator can include a variety of audio, visual, and/or audiovisual features.
In some embodiments, the mobile solar generator can include a speaker 1810 configured to output a sound and in communication with the controller 1850. In some examples, the controller 1850 can be configured to cause the speaker 1810 to output a warning sound while moving a solar array (e.g., 116) into a safe mode configuration. In the example of
In some embodiments, the mobile solar generator can generate alerts indicating that the mobile solar generator has changed configurations. In some embodiments, the mobile solar generator can include a network communication interface 1820 in communication with the controller 1850. The controller 1850 can be configured to output a signal indicative of the solar array (e.g., 116) of the mobile solar generator moving into the safe mode configuration. In some examples, the controller 1850 can output such a signal to a remote location via the network communication interface 1820. For instance, in some examples, such an alert can be output to a variety of devices to signal to a user that the mobile solar generator is in its safe mode configuration so that the user is made aware that the solar array has been adjusted, such as in response to wind. This allows a user to react in real-time to weather changes affecting the generator.
In some embodiments, a mobile solar generator can be connected to a network (e.g., an internet of things or other system) and communicate with various network components. This can allow the mobile solar generator to connect to other devices (e.g., other mobile solar generators). The mobile solar generator may also be in communication with locations or devices remote to the mobile solar generator, for example, to provide information regarding the operation of the mobile solar generator and/or to receive command or control information from such a remote location or device.
In some embodiments, the mobile solar generator can include one or more position sensors 1840 in communication with the controller 1850, position sensor(s) 1840 each being configured to detect a position of the solar array when the solar array moves between various configurations, such as from the deployed solar array configuration to the stored solar array configuration and/or the safe mode configuration. The controller 1850 can be configured to detect a position of one or more components of the solar array and, if the solar array deviates from an expected stored solar array position as the solar array moves toward a desired configuration (e.g., a stored solar array configuration or a safe mode configuration), stop moving the solar array toward the desired configuration and output an alert based on information provided by the plurality of sensors (e.g., 1830, 1840). In some examples, the alert is output via one or more lights 1800, speakers 1810, and/or to a remote location, such as via network communication interface 1820.
Similar to as described elsewhere herein, in some examples, controller 1850 can be configured to perform functions described with respect to controller 150 in
An example method for operating mobile solar generator 100 of
Some embodiments of the method can include outputting an alert that the solar array 116 is moving into the safe mode configuration. In some embodiments of the method, the alert can include one or both of an audio alert output via one or more speakers and a visible alert including illuminating one or more lights. Some embodiments of the method include communicating an alert to a remote location indicating that the solar array 116 has moved from the deployed solar array configuration to the safe mode configuration.
The method can include moving the solar array 116 from the deployed solar array configuration into the safe mode configuration. In some embodiments of the method, moving the solar array 116 from the deployed solar array configuration into the safe mode configuration can include lowering the solar array 116 from a deployed height to a safe mode height.
The various heights can be defined relative to one another. In some embodiments of the mobile solar generator 100, the deployed solar array configuration can include the solar array 116 being at a deployed height relative to the housing 118. The safe mode configuration can include the solar array 116 being at a safe mode height relative to the housing 118. The safe mode height can be less than the deployed height. In some examples, the safe mode height is different from a height associated with the stored solar array configuration.
Additional solar panels can be included in the mobile solar generator. In some embodiments of the method, the solar array 116 can include a plurality of solar panels 102. When the solar array 116 is in the safe mode configuration, approximately one third of the solar panels 102 of the solar array 116 can be unshaded by other solar panels 102 of the solar array 116, and approximately two thirds of the solar panels 102 of the solar array 116 can be shaded by other solar panels 102 of the solar array 116. For instance, in an example embodiment, in the deployed solar array configuration, 12 solar panels 102 are exposed, while in the safe mode configuration, four solar panels 102 are exposed and the remaining eight solar panels 102 are shaded.
The methods of use can incorporate the thresholds described above. In some embodiments of the method, the predetermined threshold can include a first predetermined threshold corresponding to a first wind speed. The method can include, if the wind information satisfies a second predetermined threshold corresponding to a second wind speed, the second wind speed being greater than the first wind speed, moving the solar array 116 into a stored solar array configuration different from the safe mode configuration.
The solar tracking capabilities of the mobile solar generator can be incorporated into the mobile solar generator. Some embodiments of the method include, while receiving electrical power from the solar array 116 in the deployed solar array configuration, moving the solar array 116 to track the position of the sun and, after moving the solar array 116 from the deployed solar array configuration into the safe mode configuration, no longer moving the solar array 116 to track the position of the sun.
The above-described methods can be completed in combination with the automated deployment process. In particular, the above-described methods can be completed in accordance with the short durations described elsewhere herein.
In some embodiments, first section 1910, second section 1920, and third section 1930 include a top surface 1912, 1922, 1932, respectively, as shown in
In some examples, solar array 1900 moves in order from the configurations of
“Outward” (shown by arrow 1980) and “inward” (shown by arrow 1990) as used with respect to a direction a top surface of a section faces can refer to whether the top surface of the section of the solar array faces toward the housing of the mobile solar generator or away from the housing of the mobile solar generator. As described herein, in some embodiments, solar array can be moved about one or more axes of rotation, including, for example, tilting. In some cases, a solar array section can face outward, away from the mobile solar generator housing, while tilting, for example, to face the sun. Thus, in some cases, a top surface of a section of a solar array facing direction does not necessarily mean that the top surface is facing straight up relative to a ground surface or a level plane. Similarly, a top surface of a section of a solar array facing inward does not necessarily mean that the top surface is facing straight down relative to a ground surface or a level plane.
As shown in the example of
In the illustrated examples of
In some examples, moving a foldable solar array from a stored solar array configuration to a deployed solar array configuration includes unfolding a folding array of solar panels such that the second set of one or more solar panels (e.g., in second section 1920) unfolds with respect to the first set of one or more solar panels (e.g., in first section 1910) from a position underneath the first set of one or more solar panels to the position not underneath the first set of one or more solar panels and a third set of one or more solar panels (e.g., in third section 1930) unfolds with respect to the second set of one or more solar panels from a position underneath the second set of one or more solar panels to a position not underneath the second set of one or more solar panels. In some such examples, the second set of one or more solar panels can unfold with respect to the first set of one or more solar panels and the third set of one or more solar panels can unfold with respect to the second set of one or more solar panels simultaneously. Simultaneous unfolding can increase the speed at which the solar array moves into the deployed configuration.
In some embodiments, solar array 1900 can include a mechanical coupling between the first 1910, second 1920, and third 1930 sections comprising the first, second, and third sets of one or more solar panels, respectively. The mechanical coupling can be configured such that each relative folding relationship between the third section 1930 and the second section 1920 corresponds to a single relative folding relationship between the second section 1920 and the first section 1910 that occurs simultaneously with the corresponding folding relationship between the third section 1930 and the second section 1920.
In some examples, second section 1920 is pivotable relative to first section 1910 about an axis, for example, shown at 1915 in
In some embodiments, solar array 1900 can be moved between the configurations shown in
For example, as described herein, in some embodiments, a controller is configured to move a solar array from a deployed solar array configuration (which may include the configuration of
In some examples, a safe mode configuration and a stored solar array configuration can include a closed configuration as shown in
In some examples, a controller can be configured to move the solar array 1900 to any configuration between the configurations of
In some embodiments, positioning the solar array into a cleaning configuration comprises raising the solar array above the housing (e.g., via an adjustable support pillar) while the solar array is in the configuration of
The solar array 1900 of
In some examples, the solar array includes a four-bar linkage coupled to the first section 1 and the second section 2. In the illustrated example, the four-bar linkage comprises elements 14, 4, 5, and 6. In an example embodiment, element 4 is moved by a linear actuator (e.g., a hydraulic piston) so that element 4 rotates about an axis (e.g., about axis 7). In an example, the solar array moves toward a deployed configuration as element 4 moves clockwise in the perspective of
In an example embodiment, as element 4 moves clockwise (e.g., due to being pushed or pulled at a point by a linear actuator), element 5 pushes upward on element 6, which moves upward and causes section 2 to pivot clockwise about axis 15, which can raise section 2 so that its top surface is approximately coplanar with a top surface of section 1. In some cases, the four-bar linkage between section 1 and section 2 allows for a full 180° pivot of section 2 about axis 15 driven by a single linear actuator (e.g., hydraulic piston) moving element 4.
In some examples, a solar array includes a second four-bar linkage coupled to the first section 1 and the third section 3. In some examples, the second four-bar linkage maintains a parallel relationship between section 1 and section 3 as the solar array moves between closed and deployed configurations. In the example of
In an example embodiment, as second section 2 moves clockwise about axis 15 (e.g., due to clockwise movement of element 4 as discussed above), it pivots about axis 11 and raises element 16, which, in turn, raises section 3. Element 16 is coupled to element 6 at axis 12, which can prevent section 3 from rotating counter-clockwise about axis 11 due to torque caused by the weight of section 3.
In some examples, the second four-bar linkage loses a mechanical advantage when element 6 and section 2 are approximately vertical.
The example of
In some embodiments, various aspects of the solar array comprise a width such that adjoining components (e.g., components pivotably coupled at an axis) have different widths and one component effectively fits inside of another.
In some examples, a solar array comprises two half-arrays, wherein each of the half arrays is movable between a closed configuration and a deployed configuration. In some such examples, each of the half arrays is movable by a single hydraulic cylinder, such as described herein. For example, in the example of
In some examples, a controller is configured to move two half arrays between a closed configuration and a deployed configuration simultaneously. Additionally or alternatively, in some examples, a controller is configured to move each half array individually. A mobile solar generator controller can cause either or both half arrays to move between the closed and deployed configurations for a variety of reasons, for example, in response to a user command or wind information provided from a wind sensor. For moving the arrays between the closed and deployed configurations can include, the controller can be configured to control motion of a respective hydraulic cylinder associated with each half array.
As described, in some embodiments, a solar array can include a plurality of solar panels that can be expanded or reduced in size, for example, for increasing the solar power generation capacity or transported, respectively.
As described herein, in some examples, a mobile solar generator can include one or more electrical inputs in addition to its electrical outputs. As described, in various embodiments, the one or more electrical inputs can be used to charge the batteries of the mobile solar generator using an external source without using the integrated power generation of the mobile solar generator (e.g., solar panels, generator, etc.). For instance, in the embodiment of
In various embodiments, a mobile solar generator can include multiple storage areas integrated into the housing for storing items such as hand tools, cables, power distribution devices, fuel storage, and the like. In some examples, the storage areas include internal cabinets and drawers.
In some examples, mobile solar generator can be pulled-behind a tow vehicle and can include features such as directional signals, brake lights, and the like in order to comply with roadway requirements for being towed. Additionally, a mobile solar generator can include brakes for its wheels that are independent from a tow vehicle's brakes. In some examples, a mobile solar generator can be configured to stand by itself independent of the tow vehicle (e.g., via outriggers in the deployed outrigger configuration such as shown in

As described, in some examples, such a series of solar panels 2302 can be attached to an adjustable support pillar 2312 with multi-axis pivot which can change heights, rotate about its axis, and tilt the series of solar panels.

Example mobile solar generators described herein can provide a variety of advantages. Some mobile solar generators described herein may be positioned at locations in which a typical diesel generator would be too loud and/or prohibited due to emissions, smell, etc. As described herein, some mobile solar generators can be deployed and/or retracted in less than a predetermined period of time (e.g., 15 minutes).
In some examples, as described elsewhere herein, some mobile solar generators include a high wind retraction feature in which a controller determines that wind levels (e.g., as measured by a wind sensor) exceed a predetermined threshold and causes the array of solar panels to move into an alternate configuration (e.g., a safe mode configuration and/or a stored solar array configuration). The high wind retraction feature can alleviate the need to have an operator visit a site and manually retract the array of solar panel for each mobile solar generator. In some mobile solar generators described herein, when the array of solar panels is deployed, all of the solar panels in the array are exposed to the sun, and when the array of solar panels is retracted, a subset of the solar panels (e.g., four of twelve) are nevertheless exposed to the sun. In this way, the mobile solar generator may be taking in solar energy even when the array of solar panels is retracted.
In general, the example mobile solar generators described herein can be configured to provide protection from environmental factors such as precipitation, dirt, wind, and temperature. Further, the example mobile generators are configured to operate in a variety of conditions.
Various examples of the disclosure have been described. Any combination of the described systems, operations, or functions is contemplated.
