A solar collector element including a wooden frame having longitudinal frame members and cross members which are fastened to a back panel is provided. The insulating material is inserted in the frame between the cross members. Located on top of the cross members and the insulating material is a pipe coil which has a plurality of lengths of pipe that run substantially horizontally at a small angle to each other, and each is provided with a heat-absorbing aluminium plate which, with one of its longitudinal edge portions, surrounds the respective length of pipe. The outward side of the framework is covered by a panel, preferably a corrugated panel of polycarbonate. When using solar collectors for dwelling houses, several such solar collector elements are placed adjacent to each other and connected in series, optionally so as to cover most of the height of the roof between the gutter and the ridge.
