This paper deals with the development of a weather data base and the performance prediction of a 50-kW dish Stirling system. An analysis of direct solar insolation data for 1985 from the site in Riyadh, Saudi Arabia was made to determine the available solar energy. A parameter study was done of the effects of component efficiencies and operating conditions on instantaneous and yearly average system efficiency using the prepared weather data. The system performance was found to be most affected by wind, mirror reflectivity, and exact placement of the receiver in the focal point of the mirror.
