<p>Apparatus for collecting radiant solar energy comprising one or more solar energy collecting assemblies each having an insulated base, sidewalls, a cover with an ordered or random array of a plurality of essentially pyramidal projections and a broad area energy absorber inside a housing defined by the base, sidewalls and cover. The pyramidal projections each comprise some faces transparent to incident solar energy and at least one internally and externally reflective face. The pyramidal configurations and angles of the pyramidal surfaces with respect to the base and the energy absorbing surface are varied depending on usage conditions to provide optimum collection of solar radiation.</p> |
