Abstract: For use with or without multi-axis orientation means, a solar energy collector and transfer apparatus features tandemly arranged solar energy concentrators intervened by energy absorber and transfer units in a generally planar unitized array with back reflectors to energize the side of the apparatus away from the sun. In a practical embodiment, the tandem energy concentrators are parabolically curved reflectors fore and aft of energy absorbing and transfer tubes which are disposed at the exit apertures of the reflectors or field focuses. A simplified fluid transport system is embodied in the apparatus together with efficient and economical supporting structure for the energy concentrators and associated absorber and transfer units.
