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.
After 25 years, your solar panels won’t necessarily need to be replaced; however, their ability to absorb sunlight will be reduced. In this blog, we’ll explain how long solar panels last, review solar panel degradation rates, and ways to make sure your solar panels last as long as possible.
The “20% rule” refers to the point at which a solar panel has lost around 20% of its original efficiency, usually after 25 to 30 years of use. Panels are generally considered to have reached the end of their warranted life once they drop below 80% of their initial performance.
After 25 years, your solar panels will likely still generate electricity, but at a lower efficiency. At this stage, you have three main options: keep them in service if they’re still performing well; upgrade to newer, more efficient models; or recycle them through an approved solar panel recycling scheme.
