Comparative Analysis of the Solar Dish Electricity Production

Abstract: Round parabolic solar mirror is often called solar or sun dish. Even when the dish is faceted into several smaller dishes (facetes) that are all focusing the sunlight in a single point (focus), it is called a solar dish. When solar radiation to electricity converter is mounted into the dish focus and the sun-tracking system is provided it could be named solar dish/converter system. Depending upon the sort of the converter two promising systems that are approaching the commercialisation can be mentioned. These are solar dish/Stirling system and solar dish/ photovoltaic (PV) system. In this paper, technical and economical aspects of the two systems are examined and compared. For that purpose two representative systems are chosen: SAIC/STM SunDishTM, solar dish with Stirling heat engine/generator, and Solar Systems SS20TM representing solar dish with concentrating photovoltaic (PV) converter. It is concluded that solar dish with concentrated PV converter could have much better cost/performance ratio. It is concluded that recently introduced thermoacoustical converter and PV cavity converter, probably designates future development of the solar dish systems.
