Expected Useful Life Of Solar Panels

Is that rule accurate.

Expected useful life of solar panels.

Home solar battery units last anywhere between 5 and 15 years. But the solar panels generating that power don t last forever. Deep cycle lead acid and agm batteries. Most solar panel companies will provide a standard 25 year warranty for the expected life expectancy of the 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. Here s a simple list. However their ability to absorb sunlight will be reduced. 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. 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. 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.

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.
