Solar panel

A solar panel comprising a generally cylindrically shaped sealed housing which is hollow and defines therein a relatively shallow generally cylindrical chamber one end of which is bounded by a surface portion of an impervious base and the opposite end of which is bounded by a disc of baked solar glass, an intermediate portion of a length of seamless heat conductive tubing coiled within said chamber in a substantially concentric spaced relation to the peripherally bounding wall thereof and in a spaced facing relation to each of said base surface and said solar glass, said coil being formed in successive loops which are substantially concentrically arranged and radially spaced to produce within said chamber a substantially extended flow path for passage therethrough of fluids, said loops being arranged in an axially displaced but closely adjacent relation to provide thereby that said loops are disposed in a plurality of planes which are relatively closely adjacent and essentially parallel and each occupied by a plurality of said loops, the respective end portions of said length of tubing being disposed exterior to said housing for the coupling of said tubing into a related system to which the solar panel is intended to apply.
