National Institute of Advanced Industrial Science and Technology (AIST) installed additional PV systems, 869 kilowatt in total (844 kilowatt of power conditioners) under the scope of "Advanced Improvement Project for Introducing Demonstration Plants of Distributed Energy Supply System". The total capacity of the PV systems in the AIST Tsukuba Center reached one megawatt. The new PV facilities consist of 5,600 PV modules and 211 grid-connected inverters (four-kilowatt in each), which are typical components for residential use in the market in Japan. Thus, the facilities are not only electrical equipment in the AIST but also research and demonstration facilities and showcases in Japan. By utilizing these PV systems, the authors are doing research on the assessment of the performance and reliability of grid-connected systems. Hundred PV systems will be monitored every one minute by using performance diagnosis system developed by the authors for the performance analysis. Annual final system yield was 1,120kWh/kW and the performance ratio was 0.74 in the first year. The total amount of generated electricity was 1,300MWh, equivalent to about 1.3% of the consumption in the AIST Tsukuba 1, 2, 3 and 7 Area.
