Solar panel solar panel lifespan

How long do solar panels last?

On average, most residential solar panels are designed to last 25 to 30 years. However, this doesn’t mean they suddenly stop working after three decades. Instead, their energy output gradually decreases over time, a process known as degradation. Tier 1 panels (like those from SunPower, REC, or LG) may retain up to 92% efficiency after 25 years.

How can I extend the lifespan of my solar panels?

Here are some tips that can help you extend the lifespan of your solar panels: Investing in a high-quality solar photovoltaic system from a reputable manufacturer like FusionSolar is the first step toward ensuring long-term performance and durability.

Are solar panels durable?

The solar industry continues advancing panel durability through improved materials, manufacturing processes, and quality control. Emerging technologies like perovskite cells and advanced encapsulation materials promise even longer lifespans and lower degradation rates. By 2030, we expect to see:

How long do photovoltaic panels last?

The U.S. Department of Energy says photovoltaic (PV) modules should last about 30-35 years. Many panels keep making electricity much longer. Your panels won’t just stop working after 30 years. They’ll make less electricity gradually but stay functional.
