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.
Most panels are also backed by warranties of up to 25 years, giving homeowners long-term peace of mind — provided the system is properly maintained and the warranty conditions are met.
