Abstract: Photovoltaic module performance data during field operation are essential to understanding the causes of degradation or failure. In this work, performance metrics were analyzed for 357 modules in a rooftop array operating for 23 years in Varennes, Quebec. Modules were studied by visual inspection, solar simulator I–V curves, and Auger Electron Spectroscopy. A statistical analysis of degradation paths was performed with the strongest correlation to performance decline linked to moisture ingress.
