Abstract
Under the Government Basic Guidelines for the new energy introduction, New Energy Development and Industrial Technology Organization (NEDO) installed and is installing 177 PV sites having a total capacity of 4860 kW from FY1992 to FY1997. Those systems have been being monitored and all the data have been collected by Japan Quality Assurance Organization (JQA). Simple operational reports have been compiled from the beginning of the project. More detailed, systematic performance analysis routine has been introduced to the existing database. Analyzed performance parameters are given by a set of 2 graphs. Detailed parameter definitions and analyzed results for selected sites are given. Statistical evaluation for the 70 available systems are also presented.
