Life Expectancy Of Pool Solar Panels

Solar cells are at the heart of every solar panel and convert the sun s light into usable electricity.

Life expectancy of pool solar panels.

The life expectancy of solar panels when you re considering investing in a solar installation wondering how long home solar panels last is a question that inevitably pops up. Performance warranties guarantee that the power output will decline at a rate set by the manufacturer usually about 0 7 each year. That shows you how confident the manufacturers are in the quality and longevity of a typical solar pool heating panel. Most panels remain productive long after their typical 20 to 25 year warranty period expires even if they have average degradation rates.

The degradation rate is partly determined by the type and quality of a panel s solar cells. The 25 to 30 year lifespan of a solar panel is significantly longer than its energy payback time or epbt. Most major manufacturers provide a 10 12 year collector panel warranty that covers manufacturer defects. Solar panels typically come with 25 year performance warranties and 10 to 12 year limited warranties.

For instance if you have installed monocrystalline panels you can continue to use them without any issue for more than 25 years. Warranties don t necessarily equal life expectancy but they are a good place to start estimating. To put your mind at ease studies have proven solar panels can last anywhere between 25 to 30 years or sometimes more.
