That means after 25 to 30 years, most high-quality panels will still generate around 85–90% of their original output. If your panels’ output drops below the level promised in the warranty (for example, below 80% after 25 years), you may be entitled to a repair, replacement, or compensation.
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.
Solar panel efficiency has seen a dramatic rise since the technology’s inception, improving from about 6% in the 1950s to over 22% for the best commercial panels in 2025, with laboratory cells exceeding 47% efficiency.
