Solar collector with an absorber flowed through by liquid, on the side of which facing the solar radiation, at a distance of one to a number of centimetres, a thin plate is arranged, the side of which facing the solar radiation is designed in such a manner that it reflects the radiation only slightly, and that both the space available between the plate and the absorber as well as the liquid line of the absorber are connected to a circulation.
