<p>A solar panel is provided including a flat or formed outer surface section which is adapted to be exposed to the direction of the sun's radiation, the outer section preferably being disposed under a suitable transparent plate, e.g. glass. A flat or formed inner sheet is provided which is closely spaced from the outer surface section by a maximum amount of 0.016 inches. Means are provided for joining the inner and outer surfaces to one another at the top and at the bottom at the peripheral edges in such a manner as to provide a hollow, fluld-tight cavity between them. Conduit means are provided as a bottom inlet distributor for allowing entrance of a fluid into the cavity and conduit means are provided as a top outlet header for removal of the fluid from the cavity. Also provided is a solar heat collecting framed panel adapted to accept the above described solar pane. To provide most efficient control and heat removal, the collector should be made of two copper sheets, the outer of which is flat, is separated 0.016" from the inner with an enclosed volume of fluid not exceeding 2.3 cu.in./square foot of panel.</p> |
