This report focuses on the analytical assessment of photovoltaic (PV) plant performance on the overall PV system level. In particular, this report provides detailed guidelines and comprehensive descriptions of methods and models used when analyzing grid-connected PV system performance.
The main objectives of this report are:
- to propose good practices for PV system monitoring today,
- to determine and understand PV system losses that cannot be assessed by direct measurements in commercial PV systems,
- to determine and understand the behavior of new PV technologies in long-term system operation,
- to learn from previous bad experiences and draw out lessons for new installations in the IEA PVPS member countries.
