# What is the life expectancy of solar panels?

Solar panels typically have a life expectancy of 25-30 years. However, the exact life expectancy will depend on the quality of the panels and the environment in which they are installed. Solar panels generally degrade at the rate of 1% per year which means that even after 25 years, they will remain approximately 75% efficient.
