We have proposed a method to evaluate the kW-value of PV system, where the kW-value is calculated as an average value of reduction in peak electricity load on the electric power utility among a few days with large peak load in a year. By using the proposed method, this paper discusses the difference in kW-value of PV system due to the difference in region considered. The evaluation is based on the actual insolation data in 45 points throughout Japan and electricity load on the electric power utility both observed in the 1990's. As results, the number of days with large reduction in peak load by PV systems is larger in Western Japan, because the solar noon is slightly late in Western Japan, resulting in the large electricity supply of PV system during the period of large electricity load. Therefore, when the kW-value is evaluated based on a number of days with large daily peak load, the kW-value of PV system would be higher in Shikoku and Kyusyu regions. However, when the kW-value is evaluated based on a number of days with large daily peak demand but with small insolation, the evaluated kW-value is not so different among regions in Japan, because the ratio of such the day is not so different among regions.
