ABSTRACT:
A solar heat collector system which is comprised of a roof or wall structure element, a conduit for heat exchange fluid in the roof or wall structure element, and a focal point reflector plate behind the conduit and in the structure element. Preferably the conduit is of a flat elliptical cross section. The flat plate-focal point collector adds an advantage of reflecting sunlight directly onto the conduit for heat exchange fluid in order to insure more efficient heat exchange between the sun rays and the fluid contained in the conduits; and the reflector directs re-radiated heat from the conduit back to the conduit.
