The present disclosure relates to carports and particularly carports that harvest solar energy.
Description of the Related Art
In today's energy market, producing electricity in a renewable way is essential.
Such a demand in renewable energy can be addressed by collecting or harvesting energy from renewable resources such as sunlight which is naturally replenished quasi perpetually.
To this end, energy production systems relying on photovoltaic panels with different configurations and/or arrangements to enhance sunlight exposure have been employed. Notably, conventional solar carports that rely on photovoltaic panels mounted onto elevated structures configured to receive vehicles, e.g. parking structures and/or garage roofs, to generate electricity while minimizing usable space occupied by the photovoltaic panels have been adopted.
Although such conventional solar carports are used, they present important drawbacks. Notably, in these conventional solar carports, the photovoltaic panels may easily be covered by light obstructing materials, e.g. dust, sand, leaves, and/or other debris, which can affect energy production, and cleaning and/or servicing these photovoltaic panels may often be required. Cleaning and/or servicing the photovoltaic panels on these conventional solar carports may be complex and time consuming tasks as these photovoltaic panels are difficult to reach or access.
Thus, a solar carport module solving the aforementioned limitations of servicing and/or cleaning the photovoltaic panels is desired.
Accordingly, one object of the present disclosure is to provide a solar carport module which overcomes the above-mentioned limitations of servicing and/or cleaning the photovoltaic panels.
The solar carport module of the present disclosure provides accessibility to the photovoltaic panels via a support structure that can be articulated to position the photovoltaic panels within reach of a user standing on the ground surface that supports the solar carport.
In one non-limiting illustrative example, a solar carport module is presented. The solar carport module includes a support structure to provide shelter to a vehicle, the support structure having a pair of trusses rotatably affixed to a ground surface on which the vehicle is parked, a plurality of photovoltaic panels mounted between the pair of trusses to provide solar electricity, a battery assembly that electrically connects the plurality of photovoltaic panels to receive, regulate, and store the solar electricity, an articulation system that rotates the pair of trusses between a shelter position and a service position, wherein in the shelter position the plurality of photovoltaic panels are substantially parallel to the ground surface and in the service position the photovoltaic panels are manually reachable by an user standing on the ground surface.

The battery assembly E-1000 can include a battery E-1100 with a battery voltmeter E-1110, a charge regulator E-1200 with a rectifier circuit E-1250 electrically connecting the plurality of photovoltaic panels B-1000 to the battery E-1100, an input voltmeter E-1310 positioned between the rectifier circuit E-1250 and the plurality of photovoltaic panels B-1000, a light detector E-1350, an output voltage adjuster E-1410 positioned between the battery E-1100 and the articulation system C-1000, and an electronic control unit D-1000 that can read the battery voltmeter E-1110, the input voltmeter E-1310, and actuate the output voltage adjuster E-1410, and the charge regulator E-1200.
The charge regulator E-1200 and the rectifier circuit E-1250 can receive, rectify, and regulate the solar input electricity SIe from the plurality of photovoltaic panels B-1000 to provide regulated input electricity RIe to the battery E-1100. The charge regulator E-1200 can prevent transferring over voltages to the battery E-1100 to enhance battery performance and lifespan by providing the regulated input electricity RIe as an average of the solar input electricity SIe over a predetermined period of time.
The charge regulator E-1200 can be a stand-alone device, as illustrated in
In addition, the charge regulator E-1200 can be coupled with the rectifier circuit E-1250, as illustrated in
The battery E-1100 can store the regulated output electricity RIe to be concurrently or later used in external elements of the carport module 1000, e.g. electrical cars, parking lighting system, or the like, through the electrical connection E-1120, e.g. electric car charging station. The battery E-1100 can be a single or a plurality of alkaline batteries, lead acid batteries, lithium-ion batteries, or the like.
The electrical control unit D-1000 can monitor and control the carport module 1000 by receiving reading signals from the battery voltmeter E-1110 indicative of a charge level of the battery E-1100, reading signals from the input voltmeter E-1310 indicative of a voltage value of the solar input electricity SIe, and reading signals from the light detector E-1350 indicative of a sunlight direction, as well as by providing to the charge regulator E-1200 command signals indicative of a voltage decrease of the solar input electricity SIe, to the output voltage adjuster E-1410 command signals indicative of a voltage increase of the solar output electricity SOe, to the articulation system C-1000 command signals indicative of a position of the pair of trusses A-1100, via the ratchet actuator C-1510 and the reversing switch C-1120.
The electrical control unit D-1000 and functionalities associated with the electrical control unit D-1000 will be described in details in following paragraphs and figures.
In a step S100, a demand or request to position the pair of trusses A-1100 in the service position is detected or recorded. The command or request to position the pair of trusses A-1100 in the service position can be detected by manual entry from the user 500, via an electrical switch or an I/O interface D-1016, e.g. graphical user interface, of the electronic control unit D-1000.
If the command or request to position the pair of trusses A-1100 in the service position is detected or recorded the process goes to a step S150. Otherwise, the process goes to a step S200.
In the step S150, the articulation system C-1000 is actuated to position and lock the pair of trusses A-1100 at the service position. The articulation system C-1000 can be actuated via the reversing switch C-120 of the electrical motor C-1100 and the ratchet actuator C-1510 of the ratchet C-1500 and through software instructions executed by the electrical control unit D-1000. Then, the process goes back to the step S100.
In the step S200, a maximum sunlight exposure position for the pair of trusses A-1100 and consequently the plurality of photovoltaic panels B-1000 is determined. The determination of the maximum sunlight exposure position can be performed via reading signals from the light detector E-1350 indicative of the sunlight direction and through software instructions executed by the electrical control unit D-1000. For example, the maximum sunlight exposure position can be determined as an intermediary position between the service position and shelter position that places the plurality of photovoltaic panels B-1000 substantially perpendicular to the sunlight direction.
In the step S300, the articulation system C-1000 is actuated to position and lock the pair of trusses A-1100 at the maximum sunlight exposure position previously determined in the step S200.
The articulation system C-1000 can be actuated via the reversing switch C-1120 of the electrical motor C-1100 and the ratchet actuator C-1510 of the ratchet C-1500 and through software instructions executed by the electrical control unit D-1000.
In a step S400, the solar input electricity SIe is regulated to provide the regulated input electricity RIe via the charge regulator E-1200 and through software instructions executed by the electrical control unit D-1000. For example, the electrical control unit D-1000 can actuate the charge regulator E-1200 to reduce, e.g. through heat dissipation, the solar input electricity SIe when voltage values of the solar input electricity SIe are above a predetermined maximum battery threshold. The predetermined maximum battery threshold can correspond to voltage values for which the battery E-1100 can be damaged.
In a step S500, it is detected if the battery E-1100 is fully charged. The full charge of the battery E-1100 can be determined with a voltage value of the battery E-1100 that is measured via the battery voltmeter E-1110, see
If the full charge of the battery E-1100 is detected, the process stops. Otherwise, the process goes back to the step S200.
