Solar thermal is a branch of the solar energy is harnessing the sun’s heat energy in the life of human beings.
It can be used domestically, such as for cooking (stoves, solar) to generate hot water (SWH) or for heating. It is also used at industrial level, where water is heated to evaporate the water vapor moves turbines to generate electricity (solar thermal power plants).
Using more is now known that solar energy is thermal solar water heaters for domestic use. These consist of two main parts, the solar collector and storage tank. The solar collector is a box about 2 m2 in which there is a series of tubes through which water, which when in contact with the sun is heated, a hot time is stored in the storage tank (a tank insulated like a thermos), where it remains hot for when needed. These heaters can produce up to 91% of hot water consumed by a family, depending on usage and the amount of sun that is in the location of the heater.
