Abstract: A solar energy collection system for receiving and collecting a concentrated supply of available energy from the sun includes a reflector having an internal structural frame covered by a thin deformable film at the front and a membrane cover enclosing the remainder of the structure. The front film has a reflective surface deformable into the desired configuration by the creation of a partial vacuum within the reflector. The reflector is driven by a two axis tracking mechanism directed by controls including a microprocessor programmed with data providing the position of the sun. The sun's rays are reflected from the reflective surface into an absorber through which working fluid circulates and which has a low radiation loss tube matrix design. The tubes are supported from a heat exchanger plate at one end of the absorber by means of rods carried by the plate which trap a beaded lip at the end of the tubes.
