Solar Hot Water
A laundry in California, USA. UU., With solar hot water panels on roof. Main articles: Solar Collector and Solar thermal A solar water heater uses the sun’s energy to heat a liquid which transfers heat to a heat storage compartment. In one house, for example, hot water can be heated and stored in a tank of hot water. The panels have a receiving plate and tubes through which fluid circulates attached to it. The receiver (usually coated with a dark selective coating) insures the transformation of solar radiation into heat, while the liquid flowing through the tubes carries the heat to where it can be used or stored. The heated fluid is pumped into an appliance energy exchanger (a coil inside the storage compartment or an external device) where it leaves the heat and then circulates back to the panel to be reheated. This provides a simple and effective way to transfer and transform solar energy.
