How Long Do Solar Panels Last? | EnergySage

A 2021 study by the National Renewable Energy Laboratory (NREL) found that, on average, solar panel output falls by 0.5% to 0.8% each year. This rate of decline is called the solar panel degradation rate. The degradation rate of your solar panels tells you how much electricity you can expect them to produce in any given year of their useful life.

How Solar Panel Efficiency and Cost Changed Over Time

Advances in technology, increased manufacturing efficiency, and government incentives have all contributed to this decline. As solar panel technology continues to evolve, we can expect the cost of solar panels to keep dropping. Innovations like more efficient photovoltaic cells and streamlined production processes will drive prices down further.
