The solar thermal energy is characterized by the use of solar radiation incident on a body in the form of heat. The equipment more disseminated, with the specific goal of using solar thermal energy are known as solar collectors.The solar collectors are heating of fluids (liquids or gases), which are classified into collectors concentrators and collectors plans, depending on the existence or non existence of devices of the concentration of solar radiation. The heated fluid may be maintained in tanks thermally isolated until their final use. The collectors concentrators are associated with applications in temperatures above 100oC, reaching temperatures of up to 400 OC to drive steam turbines and subsequent generation of electricity. Since the collectors plans are used primarily for residential and commercial applications in low temperature (about 60oC), such as: warm water bath, hot air for drying grain, heating swimming pools, hot water for cleaning in hospitals and hotels, etc. The solar collectors plans are already widely used in Brazil for water heating in homes, hospitals, hotels, etc., so as to reduce the consumption of electricity or gas.
