A system for collecting solar energy and generating fresh water. The system may include a solar energy collection sub-system, a salt water distillation sub-system, and a cooling sub-system. The solar energy collection sub-system may further include one or more solar energy collection assemblies, which may heat a thermally-conductive fluid, which may be used to generate electricity. The salt water distillation sub-system may include a pump, piping, and a distillation cavity. A natural filtration and living flora/fauna sub-system may also be included.

A system and method for collecting and distributing generated and/or solar radiation. A pulsed distribution subsystem combining a generated radiation source with a solar radiation collector is provided. Radiation from the pulsed distribution subsystem is provided to one or more discrete distribution systems; the discrete distributions systems transmit and distribute radiation, such as visible light, to one or more end use points in a facility.

A method of manufacturing a solar cell, including the steps of: forming an SiNx film over a second principal surface of an n-type semiconductor substrate; forming a p-type diffusion layer over a first principal surface of the n-type semiconductor substrate after the SiNx film forming step; and forming an SiO.sub.2 film or an aluminum oxide film over the p-type diffusion layer.

A heating and power generating apparatus comprises: a frame installed on the roof of a building and having a predetermined area; a plurality of power generating units arranged inside the frame to collect sunlight and generate electricity; and a hot water supply unit buried inside of the frame to absorb sunlight and perform heating and hot water supply. According to the present invention, hot water can be generated by sunlight in the winter to supply hot water and heat a house, and power can be generated by sunlight in the summer to supply power for cooling a room and thus conserve the electrical energy used in a cooler, thus promoting energy saving and environmental protection.

An optimally-angleable solar powered air system is a portable indoor solar heating unit that may stand upright or may be mounted to a door or window. The optimally-angleable solar powered air system has a frame having a solar panel mounted to a first side and a fan mounted to a second side of the frame. In use, the frame may stand inside a room at an angle facing the sun via a removable handle such that the solar panel is able to capture solar energy. The system may then convert solar energy into usable power to power the fan. The second side of the frame includes an air deflector which may direct airflow outwardly from the second side of the frame into the room.

A solar panel enclosure converts sunlight to electricity. To remove the large amount of heat from the enclosure a chambered heat exchanger (CHE) is thermally coupled thereto. An air temperature differential is created between chamber air in a CHE portion and chamber air within a CHE heat exchanging portion. When a threshold thermal gradient is reached, air pressure that keeps the chamber air static is overcome creating airflow within the chamber. The airflow draws cooler ambient air from a chamber inlet. Heat from the enclosure is transferred to the cool air and is exhausted from a chamber outlet.

A solar power system. A plurality of solar cells are joined to a foldable base. The foldable base has areas between the solar cells configured to fold to enable stacking of the solar cells. A voltage regulator is coupled to solar cells and an electrical connector is electrically coupled to the voltage regulator and configured to electrically couple to, and deliver an electric current to, an electrical device. In implementations a reflector is coupled to the foldable base adjacent to one or more of the plurality of solar cells, the reflector including a reflective material on a face of a flexible material, the reflective material configured to reflect light towards one or more of the plurality of solar cells. In implementations the voltage regulator is a pulse width modulation (PWM) voltage regulator. In implementations a switch coupled to the voltage regulator adjusts the voltage output between two or more levels.

A solar module includes a plurality of photovoltaic cells and a sandwich structure on which the plurality of photovoltaic cells is structurally supported. The sandwich structure includes top and bottom structural plates and an open-cell inner material located between the top and bottom structural plates.
