Expected Useful Life Of Solar Panels

What is the life expectancy of a solar array.

Expected useful life of solar panels.

But the solar panels generating that power don t last forever. A solar panel is relatively a simple device with no moving parts. Here s a simple list. 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.

3 certain factors may prolong your solar battery s life. 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. Most solar panel companies will provide a standard 25 year warranty for the expected life expectancy of the solar panels. Also solar panels which are exposed to wind fluctuating temperatures and weather do deteriorate and each year produce a little less electricity.

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. However their ability to absorb sunlight will be reduced. Deep cycle lead acid and agm batteries. Is that rule accurate.

After 25 years your solar panels won t necessarily need to be replaced. To put your mind at ease studies have proven solar panels can last anywhere between 25 to 30 years or sometimes more. Batteries used in solar arrays come with a wide range of warranties. Solar panels typically come with 25 year performance warranties and 10 to 12 year limited warranties.

The general rule of thumb is that panels will degrade by about 1 each year. 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. As a general solar industry rule of thumb solar panels last about 25 30 years. 1 however this doesn t mean the panels on your roof will stop producing electricity after a couple of decades.
