solar panel hot water heaters

Solar hot water panels are not a new technology, and were actually very popular in the 1920’s, mostly in the Florida and Southern California areas.  Solar water heaters use the energy of the sun to heat the water.  In the house, for instance, potable water could be heated and then preserved in a hot water tank Flat-plate solar-thermal collectors are generally kept on the roof, and possess an absorber plate to which fluid circulation tubes are fixed.

The conversion of the sun’s rays into heat is assured by the absorber, which usually has a dark selective surface coating. This occurs whilst liquid in the piping transports the heat to a place where for use or for storage.  Once the fluid is heated it passes the heat exchanger where it transfers the heat and goes back into the cycle back to the heating panels.  The fluid circulation in water heaters can be assisted with a mechanical pump. The motor pump can be powered by photovaltic cell. The process begins by warming a body of clean water and keeping it in a hot water cylinder.   Subsequently, solar hot water panels would be fixed on the rooftop, each one with a dark colored absorber plate finished using water circulation tubes.

Heated water is transported via tubes from the solar powered water heater directly to where the water can either be used or held in storage for later use.  Heat is released by the heat exchanger which returns chilled water to the hot water solar panels in order for it to be reheated.  This repetition of heating, making use of energy, and cooling is started afresh every day and continues the whole day for the efficacious life of the solar hot water heater.  Any business that uses a large amount of hot water, like a laundromat, finds these arrays particularly useful. Having the potiential of being a completely automated system solar hot water heaters are made of many hot water panel units.
