Abstract
This paper presents results of a preliminary design/economic study of a first-generation Point Focusing Distributed Receiver (PFDR) solar-thermal electric system optimized for application to industrial and small community power plants at power levels up to 10 MWe. Power conversion is provided by small Stirling cycle engines mounted at the focus of paraboloidal solar concentrators. The output of multiple power modules (concentrator, receiver, engine, and electric generator) is collected by means of a conventional electrical system and interfaced with a utility grid. Based on the United Stirling (Sweden) P-75 engine, a 1 MWe system employing mass-produced components (100 000 modules/year) could produce electricity at costs competitive with those projected for electricity generated by more conventional means, eg with fossil fuels.Keywords
