How Long Do Solar Panels Last

As a general solar industry rule of thumb solar panels last about 25 30 years.

How long do solar panels last. Most solar panels last 25 years with an average annual degradation rate of 50. Solar panels last about 20 years according to the federal trade commission. Solar inverters and solar batteries will need replacing within the 25 year solar panel lifespan. However this doesn t mean the panels on your roof will stop producing electricity after a couple of decades.

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. 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. Especially because your panels will not stop working after 25 years they just won t work as well.

Chances are if you installed a roof top solar system today it would last longer than your roof. 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. For instance if you have installed monocrystalline panels you can continue to use them without any issue for more than 25 years.

Polycrystalline silicon panels on the other hand are blue in color. The great news is that with proper maintenance your panel may actually run for as long as 40 50 years.
