The flat plate solar collector is a type of solar thermal panel whose objective is to transform solar radiation into thermal energy. This type of solar collector has a good cost / effectiveness ratio in moderate climates and adapts correctly to a large number of applications of solar thermal energy (heating of sanitary water, heating of swimming pools, support for heating, preheating industrial fluids , etc.).
The flat glazed solar collector is generally used in domestic water heating systems or in installations. The operating temperature is generally between 30 ° C and 60 ° C. It consists of an insulated box covered by glazing. Inside, there is an absorbent in which the heat transfer fluid circulates. The glazing blocks the infrared radiation and isolates the air space above the absorber to maintain heat.
