How long do solar panels last.

To put your mind at ease studies have proven solar panels can last anywhere between 25 to 30 years or sometimes more. Properly maintaining your solar panels will help ensure they last longer. The great news is that with proper maintenance your panel may actually run for as long as 40 50 years. The general answer for monocrystalline and polycrystalline panels is 25 years.

Especially because your panels will not stop working after 25 years they just won t work as well. Yes you read that right. 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 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. Polycrystalline silicon panels on the other hand are blue in color. Solar panels do not go bad and very rarely are they faulty or break. However this doesn t mean the panels on your roof will stop producing electricity after a couple of decades.

As a general solar industry rule of thumb solar panels last about 25 30 years. Chances are if you installed a roof top solar system today it would last longer than your roof.
