Abstract
Abstract The panel includes two thermally prestressed silicate glass plates with metalized edges to which are solder-sealed lead bars which, in turn, are solder-sealed to a tubular frame. An outer protection frame covers the plate edges. Spacer posts and elements support the plates against pressure upon evacuation. The absorber proper is centrally disposed in the evacuated chamber.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
78 words
A solar energy collector panel, comprising: a first and second prestressed silicate glass plate; a spacing frame for supporting the glass plates in spaced-apart relationship, the spacing frame including (i) a warp-resisting frame portion; (ii) yielding and deformable, upstanding metal bars soldered to said frame portion and to metalized portions of the glass plates, for sealing an interior space as defined by and between said glass plates and said frame; and an absorption means disposed in said space.
Claim 2
Dependent Claim
