Life Expectancy Of Pool Solar Panels

Solar pool heating panels last a long time.

Life expectancy of pool solar panels.

Solar panels typically come with 25 year performance warranties and 10 to 12 year limited warranties. 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. The 25 to 30 year lifespan of a solar panel is significantly longer than its energy payback time or epbt.

Performance warranties guarantee that the power output will decline at a rate set by the manufacturer usually about 0 7 each year. Most major manufacturers provide a 10 12 year collector panel warranty that covers manufacturer defects. The degradation rate is partly determined by the type and quality of a panel s solar cells. Talking about the overall lifespan of a solar panel it may live up to 25 to 30 years depending on the installation conditions and type of material used for its production.

Most panels remain productive long after their typical 20 to 25 year warranty period expires even if they have average degradation rates. For instance if you have installed monocrystalline panels you can continue to use them without any issue for more than 25 years. That shows you how confident the manufacturers are in the quality and longevity of a typical solar pool heating panel.
