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.
For example, after 5 years, if a solar panel is producing less than 96.5% of what it produced (on average) when it was installed, then they will replace it (0.7% x 5 years = a maximum 3.5% reduction in power).So after 10 years, your panels are guaranteed to produce no less than 93% of the power they did originally.ne of the primary considerations you will face when investing in solar energy for your home or business is how long the system will last. The answer to this question depends on a number of factors, and the answer can vary considerably, depending on the equipment you use, as well.
