Solar Panel Lifespan and Degradation Curve
Most solar panel warranties estimate the rate of power degradation to lie between 2% to 3% in the first year, and then 0.7% a year after that.
Photovoltaic Lifetime Project | Photovoltaic Research | NLR
PV modules typically degrade slowly—often losing less than 1% of their performance per year—making their degradation undetectable (within measurement uncertainty) for the first several years of operation.
