A solar energy collector having a body of foamed plastic and a surface configuration of generally semicylindrical recesses in closely spaced parallel relationship, the surface of said recesses being covered with reflective or absorptive foil to reflect or transmit solar energy to receiving devices such a fluid conduits or solar cells. The collector is made by laying a plurality of half-pipes into a frame, covering them with foil, pouring curable foam plastic over the pipes and removing the composite from the pipes. The receiving devices are then mounted in the recesses and interconnected.
