The output performance, the solar irradiation and the PV module temperature has been investigated for a PV system installed in south and north direction in a period of 1 year. The average solar radiation per a day in south and north direction was 4.59 kW h/m/sup 2/ and 3.14 kW h/m/sup 2/, respectively. The average temperature of PV module installed in north direction was smaller than that in south direction. We estimated the electric power of 40 kW PV system installed in north direction from the variation of solar radiation and PV module temperature for south and north direction. The ratio of the generated power in the monthly was calculated to be from 96.4% to 32.8%, which average value in a year was 66.4%.
