This means that after 20 years, you can expect your solar panels to be functioning at around 60-80% of their original capacity. Most are backed by 25- to 30-year performance warranties, and in real-world conditions, many keep producing power well beyond that. After a decade of operation, most solar panels will still perform remarkably well. After this period, the panels don't suddenly stop working but may experience a decline in efficiency, often around 10-20% less than their original. . Solar panels are often sold with performance warranties of 20 to 25 years, but that doesn't mean they suddenly stop working after that.
