A thermal panel comprises (a) a body including a solar radiation transmitting lens sheet, having opposite surfaces characterized in that solar radiation incident on one surface is focussed at one or more narrow zones at the body opposite surface, (b) a coating on said body opposite surface and defining aperture means in registration with one or more of said narrow zones, whereby solar radiation focussed at said zones may pass through said aperture means, and (c) said coating having a reflective surface facing away from said body.

In a solar radiation collecting structure, the combination comprising (a) a body including a solar radiation transmitting lens sheet, having opposite surfaces characterized in that solar radiation incident on one surface is focussed at one or more narrow zones at the body opposite surface, said one surface defining a multiplicty of outwardly convex surfaces, (b) a coating on said body opposite surface and defining aperture means including multiple apertures in close registration with one or more of said narrow zones, whereby solar radiation focussed at said zones may pass through said aperture means, said coating extending on said lens sheet between said apertures, and (c) said coating having a reflective sheet facing away from said body, said coating substantially covering the surface of said lens sheet between said apertures, said lens surface covered by said coating being substantially flat, (d) said apertures being spaced apart at said body opposite surface, and including reflective surfaced walls cooperating with said coating reflective surface to define a chamber for receiving and entrapping solar radiation passing through said apertures, there being elongated load bearing structural members associated with said lens sheet and reflective surfaced walls, (e) said chamber having an interior at the side of the coating and apertures opposite the lens sheet that is substantially free of a gaseous atmosphere, and including means contained interiorly of said chamber interior to receive incidence of said entrapped solar radiation for development of energy to be removed from the chamber.
