“There are several priorities of transformation and usage of solar energy. The first one is transformation of solar energy into heat and using of it for heating buildings, air conditioning, heating or distillation of water.
The basis of such generators of heat energy is plane solar collector that allows transforming solar energy to the energy of heat with a temperature of 160-180 F. It looks like a metallic frame with special pipes or it’s a plane box-like device that let pass the air, water or special liquids. This collector is put into heat isolation cover, with the exception of it’s working part that is subjected to the sunrays. A 9 ft. sqr. collector gives up to 20 gallons of hot water (150-170 F) per day. This solar water heats have a lot of perspectives to be used in remote desert areas or in the areas with a big number of sunny days. The prime cost of the hot water produced by the solar heaters is much lower than one produced by electric boiler or gas boiler. It doesn’t require any fuel and doesn’t pollute the environment. So the advantages of using solar water heaters are obvious.”
