SOLAR ENERGY COLLECTING APPARATUS AND METHODS Abstract of the Disclosure In solar energy collecting apparatus the prob- lems of leakage due to differential thermal expansion and contraction between different parts of the collec- tor, duplication of parts, fixed factory costs, and the unnecessary use of expensive materials are solved by using collector members made using on-site roll-form- ing machines, the assembly of parts at the job site, and collector members that connect side by side, each having a sheet metal collector plate (11) as the prin- cipal part of a weather membrane above underlying sup- port structure. A unique cover (13) and method of form- ing the cover enable use of relatively inexpensive film that is supported on side supports held to a pair of op- posed upper sidewalls (18 and 19) of the collector mem- ber so as to accommodate ready replacement of covers for individual collector members and ready attachment by joiner strips in an assembly of the collector members connected side by side. A pair of opposed lower side- walls (23 and 24) of the collector member are longitudi- nally slidable in opposed attachment members (78) rig- idly secured to the underlying support structure (71 and 72) and have a bottom wall (15) connected to the ends of the lower passage to form an air passage to transfer heat from the collector plate. The collector plate (11) is suspended from the support structure to allow for relative expansion and contraction of the collector plate and associated collector member struc- ture due to temperature changes.
