4 FAQs about Working life of photovoltaic panels

What is a 'lifespan' of a solar panel?

However, “lifespan” doesn't mean your panels suddenly stop working after three decades—it simply means their solar efficiency has declined to about 80% or lower. Many systems continue generating power well beyond their warranty period, though at a reduced capacity. The key factor here is solar degradation.

What factors affect the lifespan of solar panels?

Several factors impact what affects the lifespan of solar panels, including: Quality of Materials: Panels made with premium photovoltaic cells degrade more slowly. Weather Conditions: Extreme heat, hail, heavy snow, and strong winds can accelerate wear.

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.
