Average Solar Panel Lifespan

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.

Average solar panel lifespan.

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. 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. Solar inverters and solar batteries will need replacing within the 25 year solar panel lifespan.

For instance if you have installed monocrystalline panels you can continue to use them without any issue for more than 25 years. How long each solar panel will last primarily depends on the solar panel s composition. Properly maintaining your solar panels will help ensure they last longer. 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.

Post 2000 made panels on average degrade less than 0 4 each year. To put your mind at ease studies have proven solar panels can last anywhere between 25 to 30 years or sometimes more. From what i understand in the real world the lifespan of a solar panel is about 25 years. 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.
