How Long Do Solar Panels Last?

Thanks to a nonstop technology evolution, most residential solar panels are designed and should operate to last for 25 to 30 years before reduced energy production is noticeable.

The average degradation, according to a study from National Renewable Energy Laboratory (NREL), rate is 0.50% across all solar panels.

But even after that period, is possible solar panels continue to convert, in a less efficient rate, light from the Sun into solar energy.
