How Long Do Solar Panels Really Last? Complete Lifespan Guide
Most home panels work for 25 to 30 years. Many keep going after that with a slow drop in power each year. Good parts and simple care help them last longer. You will learn how
Most reputable manufacturers offer production warranties for 25 years or more. The average break even point for solar panel energy savings occurs six to 10 years after installation. If the panels continue to produce at a high level for another 15 years after that, you will end up saving thousands of dollars during the solar panels' lifespan.
Solar batteries typically have 10-year warranties, which is around the time their performance begins to degrade. So after 10 years, you might need to replace them to maintain peak performance. If you purchase a battery, check with your battery manufacturer for their specific warranty.
There is technically no expiration date on solar panels. However, over time, they naturally tend to become less efficient at producing energy. Some panels can also break due to physical damage from extreme weather conditions.
After 25 years, your solar panels won't necessarily need to be replaced; however, their ability to absorb sunlight will be reduced. In this blog, we'll explain how long solar panels last, review solar panel degradation rates, and ways to make sure your solar panels last as long as possible.
