Extruded metal solar collector roofing shingle

Patent ·
OSTI ID:6436955
An extruded aluminum planar roofing shingle is described with a structural capability of spanning over six feet which incorporates an integral tube which projects from its lower surface, the shingles being mounted in edge over-lapping, parallel array fashion across laterally spaced, inclined roof rafters of a building structure and being interlocked at said edges, each shingle extending the full length of the roof. Preferably, a light transmissive plate of a size corresponding generally to that of the shingle is carried by each shingle on the upper surface of the shingle and spaced therefrom to enhance heating of the extruded aluminum shingle and collection of solar heat thereby. A second layer may also be applied in such a manner that there is an insulation air space between each layer of the light transmissive plate.
