The performance of a solar collector depends not only on its thermal behavior, determining how much heat is lost to the surroundings when its temperature raises, but also on its optical behavior, determining the amount of irradiation which effectively hits the absorber and its transformed in heat on the HTF.
To simplify the system and to allow the possibility of heat pump operation in periods of cloudy weather, the solar collector does not have the usual glass cover and thermal insulation. Furthermore, lowering the temperature of the absorber reduces the heat loss of the collector, and in cloudy weather, the heat is taken from the atmosphere.
