National Renewable Energy Laboratory (NREL) studies show modern solar panels lose between 0. Panels working at 100% capacity when installed will run at about 99. Total Energy = Sum of yearly outputs; Total Loss = Initial × Years − Total Energy. Solar panel degradation refers to the gradual decline in a panel's ability to convert sunlight into usable electricity. The panels installed in dry, hot, desert places where ultraviolet radiation is especially harsh show the highest rates of degradation. Solar panels lose almost 1% of efficiency every year. . How much do solar panels degrade each year? A 2012 NREL Study suggests that on average solar panels degrade at a rate of 0. How much? That depends on the technology.
