Title:Performance of PV systems under real conditions
Issue date:2004/03/01
Description:Task 2 has collected information on the technical performance, reliability and cost of PV systems located in 15 countries. The information is entered into a Performance Database, which allows the user to select PV system data, monitoring data and calculated results as well as to export these data into spread sheet programmes. Task 2 participants have analyzed performance and reliability data for PV systems and components, both in order to ensure the quality and comparability of information in the Performance Database and to develop analytical reports on key issues. Activities to date include the work on the availability of irradiation data, tools for checking the performance of PV systems, shading effects and temperature effects as well as long-term performance and reliability analysis. This paper focuses on the final results on long-term performance and reliability issues of selected PV systems in different countries in Europe and in Japan. Particularly complete data sets and results are available from 330 grid-connected PV systems ranging from small-decentralized systems (PV roofs), dispersed systems (BIPV, sound barrier) to centralized systems (PV power plants). Performance ratios (PR) obtained from PV installations in different countries are compared on monthly and annual basis. Building integrated as well as non-integrated PV systems are compared with respect to performance ratio and reliability. Energy efficiency values of various PV array and inverter set-ups are also pooled and presented. Reduced yield analysis is summarized and demonstrated in case studies of selected PV installations
