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.
The key components susceptible to failure are the solar panels and inverter. However, high quality products tend to have long lifecycles which are reflected in the long warranties available, particularly for solar panels. A solar panel is relatively a simple device with no moving parts. Solar panels typically have 25 year output warranty and depending on the quality of the panel can be expected to last beyond this.
