Buckley, B S

A solar collector, or absorber, panels or a heat storage tank, suitable for heating water using solar energy is formed from two sheets of uncured elastic material, such as EPDM rubber, by simultaneously bonding and curing the peripheral edges of the two sheets and at spaced apart, discrete areas over most of the interior areas of the sheets. In one form one of the sheets is coated with a layer of release agent, over all areas except the discrete areas and the peripheral areas so that only such uncoated areas will bond during cure. In another form, a sheet of non-adherent plastic, slightly smaller than the two sheets and having holes or holidays to form the discrete areas, is bonded between the two sheets. In a third form, the peripheral edges are first sealed to form a chamber, then the chamber is inflated and a forming die presses together the discrete areas only. Reinforcing fibers are employed or molded, into at least one of the uncured sheets. Woven fabric sheets may be stitched or fastened together, coated with a thermosetting plastic and then formed into a panel or tank chamber as above. In the solar collector panel embodiment, at least one of the reinforcing fibers is metal, most preferably, in a metal screen to equalize temperatures between the bonded discrete areas and areas overlying liquid carrying volumes of the panel.
