Abstract

The disclosure illustrates a flat plate solar collector comprising a vacuum formed tray, of low conductivity material, such as ABS, of sufficient thickness to form a structural support. A layer of glass beaded foam is placed in the tray. A receiver of layers of thin copper with heat transfer fluid passages is positioned over the glass beaded foam. Single or double glass glazing is provided to cover the tray and reduce heat losses. Foam insulating material on the outside of the tray further minimizes heat losses. The receiver and glass beaded insulating material are secured to the tray which forms a low cost, easily manufacturable structural base for the collector.
