Average Solar Panel Lifespan

Properly maintaining your solar panels will help ensure they last longer.

Average solar panel lifespan.

How long each solar panel will last primarily depends on the solar panel s composition. From what i understand in the real world the lifespan of a solar panel is about 25 years. To put your mind at ease studies have proven solar panels can last anywhere between 25 to 30 years or sometimes more. Solar panels do not go bad and very rarely are they faulty or break.

Post 2000 made panels on average degrade less than 0 4 each year. Buyers have to replace their solar panel about 25 to 30 years. How long do solar panels last. As a general solar industry rule of thumb solar panels last about 25 30 years.

Most solar panels last 25 years with an average annual degradation rate of 50. 1 however this doesn t mean the panels on your roof will stop producing electricity after a couple of decades. For instance if you have installed monocrystalline panels you can continue to use them without any issue for more than 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.

For instance thin film solar panels made of amorphous silicon cadmium telluride or copper indium gallium selenide degrade faster than the panels that are mono and polycrystalline.
