How Long do Solar Panels Last. Generally speaking, a solar panel will last 30 years or more and lose some Â½ percent (0.5%) conversion efficiency annually. Hosing the panels off a few times during the summer and keeping leaves off them in the fall is about the only maintenance required.. Learn about the two kinds of solar system warranties that are normally offered. The first one is the panel and inverter manufacturer warranty, which are usually 20-25 years on panels and 5-10 years on the inverters.
It is also important to note that most inverters come with a life-expectancy of approximately 10 years, which is much shorter than the life of the panels themselves. Panels normally last 25 to 30 years. As a result, most inverters need replacement after about 11 years of service. Replacing an inverter is usually the most expensive aspect of a solar system, with replacement costs ranging between $3,000 and $20,000 each time. However, a long term solar warranty can be purchased to cover this cost.
