What Is The Lifespan Of Your Panels?

Solar PV panels can expect to have a working lifespan of 40 to 50 years. Solar panel degradation does occur and is 0.5% yearly on average for newer technology panels. This means that after 25 years, the solar PV panels will be producing 87.5% as much electricity as they did when they were first installed. The output warranty is at 80% productions at 25 years for most brands.
