Sažetak
Round parabolic solar mirror is often called the solar or sun dish. Even when the dish is faceted into several smaller dishes (facets) which are all focusing the sun light in the 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 on the sort of the converter, two promising systems which are approaching the commercialisation could be mentioned. These are solar dish/Stirling system and solar dish/photovoltaic system. In this paper, majority of the technical andeconomical aspects of the two systems are examined and compared. Two systems are chosen to represent this:SAIC/STM SunDishTM, solar dish with Stirling heat engine/generator, and Solar Systems SS20TM representing solar dish with concentrating photovoltaic converter. It is concluded that solar dish with concentrated photovoltaic converter can have much better cost/performance ratio. It is also concluded that recently in troduced thermoacoustical converter and photovoltaic cavity converter, probably designates future development of the solar dish systems. World’ s potential of installing solar dish systems according to geographic and climate conditions was estimated. Also, the number of solar dishes which could, installed in Croatia, cover yearly state’ s electricity consumption was calculated.
