Expected Useful Life Of Solar Panels

3 certain factors may prolong your solar battery s life.

Expected useful life of solar panels.

1 however this doesn t mean the panels on your roof will stop producing electricity after a couple of decades. 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. Most solar panel companies will provide a standard 25 year warranty for the expected life expectancy of the solar panels. The general rule of thumb is that panels will degrade by about 1 each year.

A solar panel is relatively a simple device with no moving parts. As a general solar industry rule of thumb solar panels last about 25 30 years. To put your mind at ease studies have proven solar panels can last anywhere between 25 to 30 years or sometimes more. Also solar panels which are exposed to wind fluctuating temperatures and weather do deteriorate and each year produce a little less electricity.

After 25 years your solar panels won t necessarily need to be replaced. 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. Solar panels typically have 25 year output warranty and depending on the quality of the panel can be expected to last beyond this. 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.

Batteries used in solar arrays come with a wide range of warranties. Here s a simple list. Home solar battery units last anywhere between 5 and 15 years. 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.

Deep cycle lead acid and agm batteries. Solar panels typically come with 25 year performance warranties and 10 to 12 year limited warranties. Is that rule accurate. However their ability to absorb sunlight will be reduced.
