The basic PV module (interconnected, enclosed panel of PV cells) has no moving parts and can last more than 30 years. The best way to ensure and extend the life and effectiveness of your PV system is by having it installed and maintained properly. Most of the parts on your solar system, such as solar panels, carry manufacturer’s warranties of 25 years. Other parts, such as inverters, carry 10-year warranties. Most solar systems outlast their warranties; many of the first solar systems installed more than 30 years ago are still going strong.
