Abstract:
Disclosed are fixed solar-electric modules having arrays of solar concentrator assemblies capable of separately tracking movements through one or two degrees of rotational freedom to follow the movement of the sun daily and/or seasonally. The concentrators can include optical elements to direct and concentrate light onto photovoltaic and/or thermoelectric receivers for generation of electric current.
Abstract:
A solar system is provided comprising a light receiving surface, a condensation subassembly, a water collection subassembly, and a cleaning subassembly. The expansion chamber of the condensation subassembly is thermally coupled to the light receiving surface and thermally insulated from the ambient such that expansion of compressed air in the expansion chamber, as controlled by the compressed air expansion valve, encourages humidity condensation on the light receiving surface by reducing the temperature of the light receiving surface. The water collection subassembly comprises a water collection vessel and water direction hardware positioned to direct condensed water on the light receiving surface to the water collection vessel. The cleaning subassembly comprises a water dispensing unit positioned to dispense water from the water collection vessel over the light receiving surface of the solar system.
Abstract:
A concentrator photovoltaic apparatus for controlling internal condensation includes a light receiving module including one or more photovoltaic cells in a waterproof enclosure, at least one primary lens sealed to the waterproof enclosure for concentrating sunlight, a waterproof breather membrane regulating the pressure of the air located inside the enclosure, and a regenerative desiccant in a thermally decoupled dryer tube or thermally coupled to an internal surface of the enclosure. Smaller breather membrane vents and/or positive time delays between the temperature of the desiccant and the temperature of the enclosure may prolong an adsorption phase of the desiccant, which may substantially contribute to efficiency, reliability, and autonomous control of condensation.
Abstract:
A solar cell module includes a substrate, a solar cell panel provided on one surface of the substrate, and a protective layer formed between the solar cell panel and the substrate. The protective layer is formed in the solar cell module by using vacuum or inert gas, thereby effectively preventing the solar cell module from moisture penetration.

Solar heat collector with a pipe in which flows an energetic fluid and a structure consisting of a frame of plastic material with metallic profiles encapsulated during the injection of said plastic material, which allows establishing orifices therein, providing a robust and lightweight collector with few components and dimensionally stable.
Abstract:
A solar collector or multi-glazed window includes a desiccant-filled vent which reduces chamber pressure fluctuations, thereby minimizing failure of seals, while inhibiting contamination by moisture. Excess pressure due to solar-heated gas is vented from the chamber, and insufficient pressure due to cooled gas is relieved by additional gas entering the chamber after being dried by the desiccant. Expandable chamber seals can further mitigate pressure fluctuations by enabling chamber dimensions to vary as the gas temperature changes. When the sun warms the desiccant, absorbed moisture is carried away by venting, solar-heated gas. A purging system can fill and purge the chamber, and a dry gas source can provide input gas at a slightly elevated pressure. A pressurized, gas-maintenance system can maintain a constant overpressure in a plurality of chambers. Solar absorbers can be formed by one or two corrugated sheets having fluid tubes installed in channels formed therein or therebetween.
