In this paper, the PV system in Kitakyushu Science and Research Park (KSRP) in Japan has been introduced. By analyzing the recorded data in 2002, the power generation result has been evaluated. On the basis of this, comprehensive module conversion efficiency for two different photovoltaic cells, single-crystal and multi-crystal, has been discussed. Furthermore, the factors influencing power generation amount and module conversion efficiency have been analyzed by using the single regression and the multiple regression method. And the environment contribution also has been evaluated. The results can be summarized as follows; 1) Althogh the PV system has been responsibility for little part of power consumption at KSRP, it has high reliability and stable running situation. 2) The average hourly module conversion efficiency is 10.6%, about 74.1% of comprehensive conversion efficiency with 14.3%. 3) Irradiance is the most important influence factor on power output of PV system and almost in direct proportion with power generation amount. The influence from air temperature is important than the one from wind velocity on power output, but the influence from them are both very small. 4) PV system has contributed to reduce environmental load greatly.
