Solar Panels How Long Do They Last

Most solar panels last 25 years with an average annual degradation rate of 50.

Solar panels how long do they last.

As a general solar industry rule of thumb solar panels last about 25 30 years. However the assurance from manufacturers in the shape of a long term warranty suggests that the lifespan of solar panels is at least two to three decades and likely even longer. How manufacturers calculate the loss of efficiency as stated earlier a crystalline solar panel may last up to 25 years. The general answer for monocrystalline and polycrystalline panels is 25 years.

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. Especially because your panels will not stop working after 25 years they just won t work as well. To put your mind at ease studies have proven solar panels can last anywhere between 25 to 30 years or sometimes more. Generally solar panels will last between 25 and 30 years but a number of factors complicate that estimate.

Properly maintaining your solar panels will help ensure they last longer. Solar panels do not go bad and very rarely are they faulty or break. 1 however this doesn t mean the panels on your roof will stop producing electricity after a couple of decades. The conditions under which the panels are used will also impact how long a solar panel lasts.

Yes you read that right. Chances are if you installed a roof top solar system today it would last longer than your roof. During normal circumstances crystalline panels can withstand extreme heat and cold for more than 20 years. The official word from seia solar energy industries association is that the average lifespan of a solar panel is between 20 and 30 years.
