Quick Summary
Researchers analyzed 16 years of data from over 1 million PV systems in Germany and found annual degradation is just 0.52–0.61%, roughly half prior estimates. Environmental factors like heat, frost, and air pollution affect performance, while smaller systems degrade less than larger ones, boosting long-term reliability and profitability.
