Expected Useful Life Of Solar Panels

What is the life expectancy of a solar array.

Expected useful life of solar panels.

Solar panels typically have 25 year output warranty and depending on the quality of the panel can be expected to last beyond this. The industry standard life span is about 25 to 30 years and that means that some panels installed at the early end of the current boom aren t long from being retired. However this doesn t mean that they stop producing electricity after 25 years it just means that energy production has declined by what manufacturers consider to be a significant amount. 1 however this doesn t mean the panels on your roof will stop producing electricity after a couple of decades.

Photovoltaic pv modules typically come with 20 year warranties that guarantee that the panels will produce at least 80 of the rated power after 20 years of use. Solar panels typically come with 25 year performance warranties and 10 to 12 year limited warranties. However their ability to absorb sunlight will be reduced. As a general solar industry rule of thumb solar panels last about 25 30 years.

But the solar panels generating that power don t last forever. Home solar battery units last anywhere between 5 and 15 years. Also solar panels which are exposed to wind fluctuating temperatures and weather do deteriorate and each year produce a little less electricity. Here s a simple list.

Is that rule accurate. Depending on the manufacturer solar panels performance can be guaranteed for 25 30 years but it s very possible that your panels will go on to produce electricity for longer than that. Batteries used in solar arrays come with a wide range of warranties. A solar panel is relatively a simple device with no moving parts.

To put your mind at ease studies have proven solar panels can last anywhere between 25 to 30 years or sometimes more. The general rule of thumb is that panels will degrade by about 1 each year. If you decide to install a solar battery today it s almost certain you ll need a replacement in the future to match the 20 to 30 year lifespan of your solar power system. 3 certain factors may prolong your solar battery s life.
