‘‘Analysis of PV System Performance’’

Optimizing the performance of PV power plants is increasingly important as the PV industry becomes more competitive. This workshop will present work being performed as part of the International Energy Agency (IEA) Photovoltaic Power Systems Programme Task 13 on Performance and Reliability of PV Systems. In particular, the workshop will focus on lessons learned from measuring real-world performances of PV power plants in the field. To this end, presenters will describe state-of-the-art methods and tools for PV monitoring data analysis as to better identify system problems and technology differences in diverse environments.
