How long do monocrystalline solar panels last?

Generally speaking, the degradation rate of monocrystalline solar panels is 0.5% per year. This means that, after 30 years, most monocrystalline solar panels on the residential market will produce 87% of their original power output. To learn more about solar, check out our rundown the top 17 facts about solar panels.

How long will NREL solar panels last?

NREL's median degradation rate of 0.5% means a typical solar panel system will still operate at about 90% of its original capacity after 20 years. Even with a higher degradation rate of 0.8%, your panels would keep about 84% efficiency after the same period. Some systems perform better than expected.
