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.
A key question when considering going solar is: how long does a solar panel last? PV solar panels usually have a warranty of at least 20 years. Thin film solar products tend to be less durable than conventional crystalline panels. Warranties for thin film can vary from 3 to 20 years. After decades of use, the efficiency of solar panels does decrease â most arrays will fall below 80 percent of their original efficiency within 20 years. However, if your panels still produce enough electricity for your needs, then there is no need to replace the panels.
