SYSTEMS, APPARATUS, AND METHODS FOR UTILIZING SOLAR ENERGY AND OTHER TYPES OF RENEWABLE ENERGY

TECHNICAL FIELD

This specification relates generally to the field of renewable energy, and more particularly to systems, apparatus, and methods for utilizing solar energy and other types of renewable energy.

BACKGROUND

Advances in solar panel technology make it realistic for an average family to have a system of solar panels installed on the roof of a house. The system of solar panels may then be connected to the home's existing electrical system. Installing such a system typically requires professional expertise in order to install the panels and to modify the home's electrical system. By installing solar panels in this manner a homeowner may utilize renewable energy and reduce monthly energy bills.

Other “Do-It-Yourself” systems are available which enable an individual to assemble a solar panel system which may be used to generate small amounts of power that may be needed while camping, boating, or “living off the grid.” Assembling and using such “Do-It-Yourself” systems typically includes setting up one or more solar panels and connecting the panels to a power unit. This type of assembly requires a higher-than-average level of technical knowledge; consequently, use of such systems is not realistic for many people.

The inverter device is adapted to receive the rechargeable battery via the receptacle, receive energy from the rechargeable battery, and produce an electric current via the power outlet. Advantageously, the system requires little or no technical knowledge to install and use.

FIG. 1 shows a system for utilizing solar energy in accordance with an embodiment. System 100 includes a solar panel device 110, a rechargeable battery 125, and an inverter device 160.

Solar panel device 110 includes a solar panel 112, a battery charger 115, and a support structure. The support structure is adapted to hold solar panel 112 in a desired position. In the illustrative embodiment of FIG. 1, the support structure includes a plurality of legs 185. In other embodiments, more or fewer than four legs may be used. Legs 185 may be foldable. A stand or similar structure may be used. In other embodiments, other types of support structures may be used.

Battery charger 115 is adapted to receive and hold at least a portion of rechargeable battery 125. Battery charger 115 is adapted to receive energy from solar panel 112 and to provide energy to rechargeable battery 125. Rechargeable battery 125 is adapted to be manually inserted into and manually removed from battery charger 115, and to be manually inserted into and manually removed from inverter device 160.

Rechargeable battery 125 is a battery adapted to hold an amount of energy (charge) and to be recharged when some or all of the energy has been depleted. Rechargeable battery 125 may be any suitable type of rechargeable battery.

Inverter device 160 is separate and independent of solar panel device 110. Inverter device 160 is not adapted to be coupled to solar panel device 110 or solar panel 112.

Inverter device 160 is adapted to receive rechargeable battery 125 and convert the energy stored in rechargeable battery 125 into an electrical current. Inverter device 160 includes a receptacle 168 adapted to receive at least a portion of rechargeable battery 125 and a power outlet 175 adapted to provide an electrical current. Receptacle 168 includes a cavity adapted to hold at least a portion of rechargeable battery 125. An opening on an outer surface of inverter device 160 provides access to receptacle 168. Inverter device 160 may include two or more electrical contacts adapted to connect to corresponding terminals of rechargeable battery 125 in facilitate the production of an electrical current. Power outlet 175 may be a standard 120-volt power outlet that supplies 120 volts, for example. In other embodiments, other types of power outlets may be used. For example, power outlet 175 may supply 220 volts or 240 volts, or may supply another voltage.

FIG. 2A shows solar panel device 110 and rechargeable battery 125 in accordance with an embodiment. Solar panel device 110 includes solar panel 112, battery charger 115, and a support structure that includes legs 185. Solar panel 112 is adapted to receive sunlight and generate energy. Solar panels are known. Battery charger 115 includes a receptacle 118 adapted to receive rechargeable battery 125. Rechargeable battery 125 is adapted to fit into receptacle 118.

FIG. 2B shows battery charger 115 of solar panel device 110 in accordance with an embodiment. Battery charger 115 is coupled to solar panel 112. Battery charger 115 includes a receptacle 118 adapted to receive at least a portion of rechargeable battery 125. Receptacle 118 includes a cavity adapted to hold at least a portion of rechargeable battery 125. Rechargeable battery 115 is adapted to fit into receptacle 118. In FIG. 2B, rechargeable battery 125 is shown engaged in receptacle 118. In the illustrative embodiment, battery charger 115 includes an opening on an outer surface that provides access to receptacle 118. Battery charger 115 is adapted to charge rechargeable battery 125 when rechargeable battery 125 is engaged in receptacle 118. In one embodiment, battery charger 115 includes hardware adapted to receive energy from solar panel device 112 and store the energy in a suitable form in rechargeable battery 125.

In other embodiments, battery charger 115 may be adapted to connect to and recharge rechargeable battery 125 in another manner. For example, battery charger 115 may have a first connecter that connects to a second connector disposed on rechargeable battery 125.

In one embodiment, solar panel 112 has a first side or surface having one or more solar cells (or photovoltaic cells) or another material adapted to receive light and in response generate energy (for example, in the form of a voltage or current) and a second side or surface opposite the first side/surface, for example, the second side/surface being the underside of the solar panel 112. Battery charger 115 is attached to the underside of solar panel 112 and is preferably centrally located. For example, battery charger 115 may be positioned in a manner such that the weight of battery charger 115 is evenly distributed (in at least one dimension) across the central axis of the support structure. For example, in one embodiment, a central vertical axis of the support structure passes through the center of gravity of battery charger 115. Advantageously, a central location of battery charger 115 on the underside of solar panel 112 ensures that the battery charger's mass is centrally placed and equally distributed around the central axis of the support structure, thus minimizing or eliminating any problems that may arise from an unequally distributed mass. Also advantageously, a central location of the battery charger under the solar panel maximizes protection of the battery charger (and any battery inserted therein) from rain and other weather conditions.

In an illustrative embodiment, battery charger 115 has a body having a generally rectangular prism or cuboid shape with an opening on one external side. In other embodiments, the body may have a different shape and the opening may be anywhere on the external surface of the body. The opening has a size adapted to receive rechargeable battery 125. Battery charger 115 has an interior cavity within the volume of the rectangular prism; the interior cavity functions as a receptacle for rechargeable battery 125. In one embodiment, the cavity is adapted to receive the entirety of rechargeable battery 125. In another embodiment, the cavity is adapted to receive a portion of the body of rechargeable battery 125. The opening functions as a port allowing the rechargeable battery to be inserted into and removed from the cavity.

In one embodiment, a user may insert rechargeable battery 125 into the opening of battery charger 115. When inserted in this manner, rechargeable battery 125 slides or otherwise moves entirely into the interior cavity of battery charger 115 and connects to one or more connectors within battery charger 115. The connectors are adapted to transfer energy (for example, in the form of a current) from solar panel 112 into rechargeable battery 125. Rechargeable battery may be recharged in this manner. Subsequently, the user may remove rechargeable battery 125 from battery charger 115.

FIG. 2C shows inverter device 160 in accordance with an embodiment. Inverter device 160 includes a receptacle 168 and a power outlet 175. Receptacle 168 is adapted to receive at least a portion of rechargeable battery 125. In FIG. 2C, rechargeable battery 125 is shown engaged in receptacle 168. In the illustrative embodiment, an opening on the top side of inverter device 160 provides access to receptacle 168. Inverter device 160 is adapted to receive power from rechargeable battery 125 when rechargeable battery 125 is engaged in receptacle 168 and to provide power in the form of an electrical current via power outlet 175. Inverter device 160 includes hardware adapted to receive energy from rechargeable battery 125 and to produce an electrical current via power outlet 175. Inverter device 160 may receive from rechargeable battery 125 energy in a first form, such as a direct current, and convert the energy to a second form, such as an alternating current. In one embodiment, power outlet 175 is a standard 120-volt outlet. In other embodiments, power outlet 175 may be a different type of power outlet.

In other embodiments, inverter device 160 may be adapted to connect to and receive energy from rechargeable battery 125 in another manner. For example, inverter device 160 may have a first connecter that connects to a second connector disposed on rechargeable battery 125.

System 100 advantageously requires little or no technical knowledge to install and use. Accordingly, anyone can easily install and use the system to utilize solar energy.

In accordance with an illustrative embodiment, a user places solar panel device 110 in a suitable location where it is exposed to sunlight. For example, the user may place solar panel device 110 in a sunny location in the user's yard. In one embodiment, no electrical connections need be made in order to set up solar device 110. The user then manually inserts rechargeable battery 125 into receptacle 118 of battery charger 115.

After the user has placed solar panel device 110 in a desired location and inserted rechargeable battery 125, solar panel 112 of solar panel device 110 receives sunlight and generates energy. The energy is transmitted to battery charger 115 and is stored in rechargeable battery 125.

In an illustrative embodiment, when rechargeable battery 125 is fully charged, the user manually removes rechargeable battery 125 from receptacle 118 and carries rechargeable battery 125 into the user's home. Supposing that the user wishes to use rechargeable battery 125 to power a lamp located in a room of the user's home, the user places inverter device 160 in the room, next to the lamp. FIG. 3 shows a lamp 340 and inverter device 160 in accordance with an embodiment. Lamp 340 includes a power cord 390 with a plug 345 adapted to fit into and receive power from a standard power outlet.

In the illustrative embodiment, the user places rechargeable battery 125 (which is fully charged) into receptacle 168 of inverter device 160. The user also inserts lamp plug 345 into power outlet 175 of inverter device 160. FIG. 4 shows lamp 340 and inverter device 160 in accordance with an embodiment. In FIG. 4, lamp plug 345 is inserted into power outlet 175 of inverter device 160.

When the lamp is plugged into power outlet 175 of inverter device 160, energy from rechargeable battery 125 is converted into electrical current and provided to lamp 340. In this manner, lamp 340 is powered by rechargeable battery 125 until the energy stored in rechargeable battery 125 is depleted.

Existing solar power devices include a solar panel and a “power station” device adapted to connect directly to the solar panel. The device may include one or more power outlets. The device may be adapted to receive energy from the solar panel and to provide power via the power outlet(s). These devices can be useful for outdoor activities such as camping or “living off the grid.” However, these devices are typically sizable, heavy, bulky, and cumbersome, and difficult for many people to carry. Furthermore, typically it is necessary to use one or more connectors to connect the solar panel to the power station. Many people who are not technically inclined find it difficult to connect and disconnect these devices to a solar panel.

Consequently, these existing “power station” devices are impractical and inconvenient for home use. In order to use one of these existing devices to power an appliance within the home, it would be necessary either to run a wire from the device into the home (while the device is located outdoors, connected to the solar panel), or to disconnect the device from the solar panel, carry it into the home, and connect it to the appliance. However, running a long wire from the yard into the home is not only technically challenging for many people but is also potentially dangerous. On the other hand, power stations are typically heavy and bulky; therefore, carrying the power station between the yard and inside the home is difficult or impossible to do for many people. Consequently, both of these options are inconvenient, impractical, or even impossible for many people.

Advantageously, the inventive systems, devices, apparatus, and methods described herein solve the problems associated with existing systems. The inventive systems described herein make it possible for a user who is not technically inclined and/or is not capable or desirous of carrying a large, cumbersome power station back and forth between the interior of a home and the yard to use a solar panel to power an appliance within the home. The user does not need to connect/disconnect a “power station” device but instead needs to perform the much easier tasks of inserting and removing a battery from the battery charger of the solar panel device, carrying the battery from the yard into the interior of the home, inserting the battery into the inverter device within the home, and plugging the appliance into the inverter device. The inverter device remains permanently inside the home. Only the battery need be transported between the exterior and interior of the home. The relatively small battery is significantly lighter in weight than a “power station” device or inverter device, and therefore is significantly easier to carry.

Advantageously, systems, devices, and methods described herein may be used to provide power in homes and in villages in areas of the world where electricity is not readily available.

FIG. 5 shows an inverter device in accordance with another embodiment. Inverter device 560 includes a receptacle 568 adapted to receive rechargeable battery 125, a power outlet 575, and a power cord 530. For example, power cord 530 may be adapted to fit into a standard 120-volt power outlet disposed in a wall of the user's home. In FIG. 5, lamp 340 is plugged into power outlet 575 of inverter device 560, and power cord 530 of inverter device 560 is plugged into a power outlet 550 in a wall of the user's home. Rechargeable battery 125 is inserted into receptacle 568 of inverter device 560.

Advantageously, inverter device 560 is adapted to draw power first from rechargeable battery 125. After the energy stored in rechargeable battery 125 is depleted, inverter device 560 draws power from power outlet 550 (in the wall of the user's home). In this manner, the user may advantageously ensure that power is provided to lamp 340 continuously and without interruption—first from rechargeable battery 125, and second, from the electrical system of the user's home.

In other embodiments, an inverter device may include a plurality of receptacles adapted to receive rechargeable batteries and/or a plurality of power outlets adapted to produce electrical current. Thus, advantageously, such an inverter device may enable a user to use multiple rechargeable batteries to power one or more appliances for a longer period of time.

FIG. 6 shows an inverter device in accordance with another embodiment. Inverter device 660 includes a plurality of receptacles 668-A, 668-B, and 668-C. Inverter device 660 also includes a plurality of power outlets 675-A and 675-B. In other embodiments, more or fewer than three receptacles and more or fewer than two power outlets may be included.

Each receptacle 668-A, 668-B, 668-C is similar to receptacle 168 of inverter device 160 shown in FIG. 1. Thus, each receptacle 668 is adapted to receive at least a portion of a respective rechargeable battery. In the illustrative embodiment, three rechargeable batteries 625-A, 625-B, 625-C are shown. Each rechargeable battery 625 is similar to rechargeable battery 125 of FIG. 1.

In other embodiments, a system similar to the system of FIG. 1 may be used to utilize other forms of renewable energy. FIG. 7 shows components of a system for utilizing wind energy in accordance with an embodiment.

Advantageously, adjustable support element 935 as shown in FIGS. 9B-9D may be manually adjusted to a selected position. For example, a user may move adjustable support element 935 to a selected position to ensure that solar panel 912 is oriented at an angle to receive an optimal amount of sunlight. The user may move adjustable support element several times throughout the day as the sun travels across the sky.

Advantageously, the feature enabling a user to manually control the position of adjustable support element 935 allows the user to adjust the position of solar panel 912 to maximize the amount of solar energy received by the solar panel, and thus to maximize the amount of energy stored in a rechargeable battery.

In accordance with another embodiment, a solar panel device includes a solar tracking system that estimates or determines a position of the sun and automatically moves adjustable support element 935 to place solar panel 912 in a desired orientation relative to the position of the sun.
