Analysis of Long-Term Performance of PV Systems

Abstract

This report describes the activities, conclusions and continued efforts undertaken in Subtask 1 by the participating countries in IEA-PVPS Task 13. Subtask 1 examines the PV power plant as a system. It collects and studies the data supplied from installed operating PV plants from different countries in order to understand better the efficiency and reliability of the current state of the art. Three Activities were defined for Subtask 1 as follows: Activity 1.1: Database and Analysis of PV systems Activity 1.2: Statistics on the operation of PV systems in operation for more than 5 years Activity 1.3: Failure analysis of operational PV systems in an attempt to understand cause and effect in PV system failure
