How Long Do Solar Panels Last? | EnergySage

Solar panels generally last for 25 to 30 years. Solar panels slowly degrade, resulting in less and less electricity production over time. Solar panels can produce power after 25 to 30 years but at a significantly lower rate than their original output. Your solar panels'' warranties can help you estimate how long your solar panels will last.

Photovoltaic (PV) Solar Panels

Under typical UK conditions, 1m 2 of PV panel will produce around 100kWh electricity per year, so it would take around 2.5 years to "pay back" the energy cost of the panel. PV panels have an expected life of least 25 to 30 years, so even under UK conditions a PV panel will generate many times more energy than was needed to manufacture it.
