ABSTRACT:
A solar energy collector is made up of a first flat flexible sheet preferably of silicone, and a first sinuous sheet also preferably of silicone, sealingly adhered to the first sheet along a plurality of spaced parallel lines to provide a series of substantially parallel ducts which carry a liquid heat transfer medium. Either the first flat sheet or first sinuous sheet incorporates solar energy absorbent material. A backing member which may include a sheet of reflective foil and a layer of foam insulation is adhered to the opposite side of the first sinuous sheet to form a plurality of substantially parallel air channels under the ducts. Desirably, a solar window which includes a second sinuous sheet with a second flat sheet adhered to the upper amplitudes thereof is adhered to the first flat sheet along the lower amplitudes to space the second flat sheet from the first flat sheet thereby providing a multiplicity of insulative air channels.
