How Long Do Solar Panels Last?
The average solar panel has an operating lifespan of 25 to 30 years, and even after decades of continuous use, most panels still retain approximately 80% of their original efficiency. In other words, solar panels don't suddenly stop working after a few decades—they simply produce electricity at a slightly reduced rate.
