An A-Frame solar panel array system is configured to produce a high amount of electrical power for a given amount of ground space with a plurality of solar panels on both a forward beam and a plurality of solar panels on a trailing beam in an elevated position above the ground. This elevated positioning enables more solar panels to be configured over a given amount of ground area. The solar panels are spaced along the trailing and forward beams with a vertical offset between the trailing and forward beams to enable sunlight to pass therethrough to enable exposure to sunlight, through the forward beam array of solar panels onto the trailing beam array of solar panels. A solar panel actuator is configured to rotate the solar panels for increasing solar panel exposure throughout the year. The solar panels may only be configured to rotate trailing/forward.

A solar magnification and shading apparatus, which may include a solar panel, having a front surface; a light controlling layer, having an underside and a top side, and positioned above the front surface of the solar panel such that a total area of the underside of the light controlling layer covers at least a total area of the front surface of the solar panel; and a magnification layer, having a bottom side and positioned above the top side of the light controlling layer such that a total area of the bottom side of the magnification layer covers at least a total area of the top side of the light controlling layer.

A solar powered VTU and systems and methods for the same are provided. A solar energy harvesting device and an energy storage device are electrically connected to an electronic display within a housing. A support extends between the housing and the solar energy harvesting device such that a bottom surface of the solar energy harvesting device is elevated directly above, and is spaced apart from, a top surface of the housing. The solar energy harvesting device has a first footprint, and the housing has a second footprint. The first footprint is larger than, and directly overlies, the second footprint.

A solar energy roof tile, thermally and/or electrically conductively connected to an adjacent solar energy roof tile, includes a lower face for placing on at least some regions of a roof construction, an upper face opposite the lower face formed at least in some regions by a solar energy utilisation module, two opposite lateral walls, a rear face connecting the lateral walls, and a front face opposite the rear face that connects the lateral walls. The two lateral walls, the rear face and front face together connect the lower and upper faces, such that a cavity is formed between the two lateral walls, the rear face, front face, and lower and upper faces. The lower face has, in the region of the front face, a lower opening for providing access. The upper face has, in the region of the rear face, an upper opening for providing access into the cavity.

A solar energy system includes solar panels supported by support trays which include cooling fluid passageways to allow a cooling fluid to convect heat from the solar panels to a static air heat exchanger. The system includes an atmospheric moisture extraction system to periodically cool air from the heat exchanger by alternately releasing the hot static air into one of two water piston units which are in fluid communication with one another, discharging previously discharged hot air from the second of the water piston units, and afterwards drawing in fresh cool air into the second water piston unit, and the heat exchanger, all by the selected sequential use of control valves under the guidance of a control unit. The fresh cool air is drawn into the water piston units through an orifice, condensing water vapor in the air into liquid water in the water piston units.

A method of passive cooling for a high concentrating photovoltaic, the high concentrating photovoltaic, includes a photovoltaic receiver, a parabolic dish reflector and a plurality of thermally conductive heat pipes having a direct thermal contact between the receiver and the reflector to transfer excessive heat. The method includes receiving sunlight by the parabolic dish reflector, reflecting the sunlight towards the photovoltaic receiver that converts the sunlight into electricity and heat, transferring the heat through the thermally conductive heat pipes and absorbing the heat by the reflector serving a dual purpose as a heat sink. A reduction in weight and cost is accomplished by incorporating the flat heat pipes.

A cooling system for a photovoltaic panel including micro flat heat pipes (HP) integrated with thermoelectric generators (TEG) and a cooled water reservoir for cooling the working fluid in heat pipes. The cooled water in the reservoir is pumped from the condensate pan of an air conditioner. Experimental results show that cooling system reduced the average temperature of the panel by as much as 19° C. or 25%. Further, the output power of the photovoltaic panel increased by 44% when the photovoltaic panel was used in a very hot climate (30-40° C.). An additional two watts of power was generated by the TEGs.
