This paper presents results of measurements and analysis on grid-connected PV generation systems installed on 132 residential houses in Tokyo and Kanagawa area. The annual PV efficiency along with its parameters as well as the effect on CO2 emission reduction and on power demand peak cut are shown based on the data obtained from October 1998 to September 1999. Result, of the analysis is that configuration of installed panel, module temperature and inverter efficiency have dominant effect on PV system efficiency. Single-panel configuration has higher efficiency than double panel configuration where two panels are installed on each inclined plane of the roof. The latter configuration suffers from decrease in efficiency by 20% in the winter season. The efficiency of single panel configuration decreases by 0.28% as the backside temperature elevates one degree. It was observed that the smaller the DC input under a certain threshold, the lower the efficiency was. The PV system installed demonstrates the contribution to 250kg-C/year of CO2 emission reduction and 1.15kWh/h of power load peak cut per house on average.
