A solar panel has a series of channels through which water or other fluids may flow for exposure to and heating by solar radiation. Common to all the channels are inlet and outlet manifolds through which, respectively, the water is directed into and discharged from the channels. Construction of the panel is simplified and is rendered economical by fashioning of the same from a pair of superposed, inexpensive metal sheets, as for example roofing tin. The sheets are readily preformed with the manifolds and channels, in such fashion that when the sheets are connected along their peripheries by means of mechanical expedients well known in the sheet metal art, the several channels are automatically defined between the sheets, and are further automatically brought into communication with the inlet and outlet manifolds. By means of spot welding or the like, the sheets are firmly, permanently connected together, and the spot welding arrangement permits a cross flow between channels, to assure maximum exposure of the liquid to the effects of solar radiation. A panel assembly is also disclosed, making use of the solar panel described above. The panel assembly is similarly inexpensively formed, through the provision of a supporting frame readily fashioned from an extrusion of aluminum or the like, said frame being designed with inwardly facing slots, adapted respectively to receive an outer glass panel, an inner glass panel, the solar panel disclosed above, a plywood base, and insulation interposed between the panel and base.

A solar heat collector panel comprising: a first sheet having an inlet and an outlet manifold; and a second sheet in superposed relation to the first sheet and connected at its periphery to the first sheet, the second sheet having a plurality of channels communicating with and extending between the inlet and outlet manifolds, the inlet and outlet manifolds being formed in closely spaced relation to the respective, opposite ends of the first sheet as corrugations formed out of the material of the first sheet, the material of the first sheet being otherwise generally flat between the opposite ends thereof, said corrugations being disposed wholly to one side of the general plane of the first sheet, the channels of the second sheet being defined by a plurality of closely spaced, parallel corrugations extending substantially from end to end of the second sheet between the inlet and outlet manifolds of the first sheet, said corrugations of the second sheet being pressed out of the general plane of the second sheet in a direction opposite to that in which the corrugations of the first sheet are extended, the opposite ends of the corrugations of the second sheet being disposed in communication with the corrugations defining said inlet and outlet manifolds of the first sheet, the material of the first and second sheets being spot welded at locations spaced along the lengths of said sheets and occurring between adjacent corrugations of the second sheet, the sheets being spaced apart at locations between the spot welds providing cross-flow areas between adjacent corregations of the second sheet.
