A water producing system for a photovoltaic panel may include a moisture collection layer, a liquid transfer mat, and a moisture collection substrate. The moisture collection layer may collect moisture from condensation and direct moisture away from the photovoltaic panel. The liquid transfer mat may include a plurality of tubes through which a chilled heat transfer liquid passes. The moisture collection substrate may include a thermally conductive material. The chilled heat transfer liquid within the liquid transfer mat may absorb heat from the photovoltaic panel and from ambient air through the moisture collection substrate, thereby reducing a temperature of the photovoltaic panel and condensing water on the moisture collection substrate to produce water.

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 photovoltaic junction box comprising a diode module and a circuit board disposed in a box body, and a heat sink mounted on the outer surface of the box body. The diode module is attached to the back side of the heat sink and is electrically connected to cooper conductor. The heat sink is made of aluminum material and a heat-absorbing layer is provided inside the heat sink. The heat-absorbing layer is close to the diode module. The aluminum heat sink provides great thermal conductivity, therefore, can greatly increase the cooling capacity of the junction box. In addition, because metal material for higher temperature resistance is used instead of lower temperature resistance plastic material, the box body would not deform as easy, greatly increase the safety and reliability of the junction box.
