One of the most common questions asked: How long do solar panels last? The short answer? Most quality solar panels last 25 to 30 years or more with proper maintenance. Even after that, they don’t stop working—they just operate at slightly lower efficiency.

In the first 10–15 years, most systems maintain over 90% of their original output. By year 25, that may drop to around 80%, but that’s still substantial energy savings! Modern panels are built to withstand weather, hail, and time.

Knowing how long do solar panels last helps you plan your ROI and future upgrades. Plus, many manufacturers offer 25-year performance warranties for peace of mind.
