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.
As more people have gone solar, the cost of solar panels has come down. The federal tax credit covers 30% of the solar system cost, and in some states there are additional local and utility rebates to offset retail price. You own the solar panel system and its expected useful life is 30+ years. On average, top tier electricity prices have increased about 5% per year for the last 30 years.
