Abstract
Abstract A reduction of first cost and an increase in solar heat collection efficiency are primary considerations. Heat absorbing liquid is confined to a narrow unobstructed path, with wide flairing wings exposed directly to the sun. The need for painted heat absorbing surfaces is largely eliminated. Transparent or translucent cover is easily removable and replaceable.

Claim 1
Independent Claim
221 words
A solar heat collecting panel, comprising a tray, a metallic darkened surface within said tray, plastic foam heat insulation between said tray and said darkened solar heat collecting sheet metallic surface, said surface having alternate ridges and valleys running lengthwise said sheet metallic surface, a solar light and heat penetrating fibrous reinforced heat hardened corrugated plastic surface, spaced apart from said hill and valley darkened sheet metal surface, and fastened firmly to the sides and the ends of said tray, resilient means sealing the space between said tray and said solar light and heat penetrating corrugated plastic surface, screws positioned in and penetrating said resilient means and the concave portions of said corrugated sheet plastic surface, and also penetrating and being fastened into said tray across one end of said corrugated plastic surface, a liquid admitting manifold near one end of said metallic surface with holes positioned within said manifold to direct streams of solar heat collecting liquid from said manifold into the valley portions of said solar heat collecting darkened sheet metallic surface, and means for removing solar heated liquid from the end of the heat gathering darkened sheet metallic surface opposite to the end of the sheet metallic surface where said solar heat gathering liquid was first admitted in order to flow down through said darkened sheet metallic valleys.
