A energia solar térmica se caracteriza pela utilização da radiação solar incidente em um corpo sob a forma de calor. Os equipamentos mais difundidos com o objetivo específico de se utilizar a energia solar térmica são conhecidos como coletores solares.
Os coletores solares são aquecedores de fluidos (líquidos ou gasosos), sendo classificados em coletores concentradores e coletores planos, em função da existência ou não de dispositivos de concentração da radiação solar. O fluido aquecido pode ser mantido em reservatórios termicamente isolados até o seu uso final. Os coletores concentradores estão associados a aplicações em temperaturas superiores a 100oC, podendo alcançar temperaturas de até 400oC para o acionamento de turbinas a vapor e posterior geração de eletricidade. Já os coletores planos são utilizados, fundamentalmente, para aplicações residenciais e comerciais em baixa temperatura (por volta de 60oC), como: água aquecida para banho, ar quente para secagem de grãos, aquecimento de piscinas, água aquecida para limpeza em hospitais e hotéis, etc.. Os coletores solares planos já são largamente utilizados no Brasil para aquecimento de água em residências, hospitais, hotéis, etc., visando à redução do consumo de energia elétrica ou de gás.
Solar thermal energy is characterized by the use of the solar radiation incident on a body in the form of heat. The most widespread equipment with the specific goal of using solar thermal energy are known as solar collectors. The solar collectors are radiators of fluids (liquids or gases), being classified into collectors and concentrators collectors plans, depending on the existence or not of concentration of solar radiation. The heated fluid can be kept in tanks that are thermally isolated until its final use. The collectors concentrators are associated with applications at temperatures above 100oC, reaching temperatures up to 400oC to drive steam turbines and the later generation of electricity. Collectors already plans are used primarily for residential and commercial applications at low temperature (around 60oC), such as: heated water for bathing, hot air for drying of grains, heating of swimming pools, heated water for cleaning in hospitals and hotels, etc.. The solar collectors plans already are widely used in Brazil for water heating in homes, hospitals, hotels, etc., to reduce the consumption of electricity or gas.

The thermal energy is characterized by the utilization of incident solar radiation into a body in the form of heat. The most widespread equipment with the specific aim of using solar thermal energy are known as solar collectors.
Solar collectors are fluid heaters (liquid or gaseous), are classified in concentrators and collectors flat collectors, depending on whether or not devices for concentrating solar radiation. The heated fluid may be kept in thermally insulated tanks until its end use. Concentrators collectors are associated with applications at temperatures above 100 ° C and can reach temperatures of up to 400oC to drive steam turbines and subsequent generation of electricity. As for the flat collectors are used primarily for residential and commercial applications at low temperature (around 60oC), as heated water for bathing, hot air for drying grain, heating pools, heated water for cleaning in hospitals and hotels , etc .. the flat solar collectors are already widely used in Brazil for water heating in homes, hospitals, hotels, etc., in order to reduce the consumption of electricity or gas.
