Abstract
A glass, evacuated, solar collector panel, formed by a mirrored bottom sheet, structured in a series of parallel linear troughs, each approximately an ideal concentrating surface and terminating at opposite ends in approximately perpendicular linear concentrating troughs, and a top window sheet. The top and bottom sheets being joined to provide a vacuum envelope. A solar selective absorbing tube network having an input and output passing through the vacuum envelope, fixed intermediate the top and bottom sheet in the vacuum. The tube network including a plurality of parallel longitudinal tube members terminating at opposite ends in respective manifold tubes. Each tube member and manifold tubes positioned at the approximate concentration point of such series of parallel troughs and opposite troughs, respectively. Such solar collector panel also serving as an energy shield by having low transmittance of heat and radiant energy of visible and infrared wavelengths.
