A solar collector includes a heat-insulated body with transparent coating, absorber and branch pipes for water supply and discharge. The absorber is arranged of two metal sheets laid one over another, hermetically connected to each other along the perimeter with formation of channels in those by means of connection with any known method for water circulation, at that the upper sheet of absorber is covered with black electrographic powder, this is substantially sintered with the metal sheet in the sun, this provides better absorption of sun rays and heat emission. |
