An electric power generating system using solar heat to operate a Stirling engine driven alternator is presented in detail and analyzed. The Dish Stirling Solar Thermal Electric Power System (DSSTEP) is an array of modular generating units consisting of paraboloidal concentrators which focus the incident solar flux at the focal plane to produce the high temperatures needed for efficient operation of the heat engine. The concentrator, made of back silvered glass for superior reflectivity and greater erosion resistance has a diameter of 10 m. The Stirling Engine receives the heat produced by the generating units and through heating and cooling of the working fluid (helium at 1500 F under 2500 psi pressure) drives the piston and generates power. The Dish Stirling Solar Receiver (DSSR) consists of four quadrants, each containing 12 copper tubes (coated with an Alloy 617 shell) 0.265 in O.D. and 0.145 in I.D. Metallographic studies of specimens under simulated operating conditions gave no evidence of problems and a receiver is being constructed for a full system test.
