For accomplishing same demand of power output of 25(kW)_e in tests sites having different intensity and distribution of direct solar radiation, it needs to take matching of collector/receiver and engine/generator systems. In such a case, collector size is sometimes adjusted. In this study, diameter of the collector is decided by using design point solar radiation, which is defined sun of average and 1σ (σ : standard deviation) of distribution of maximum direct solar radiation for a day during a year in test sites. Naha in Japan. seoul, Pusan and Cheju in korea are selected as test sites for simulation. The result show that average power output for system operating time is in the range of 9-13(kW)_e and it is necessary to investigate determining method of design point solar radiation.
