How long do solar panels last on roof.

As a general solar industry rule of thumb solar panels last about 25 30 years. However this doesn t mean the panels on your roof will stop producing electricity after a couple of decades. This is the industry standard warranty from tier 1 manufacturers. 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.

In reality solar panels can last quite a bit longer than that. 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. How long do solar panels last.

For instance if you have installed monocrystalline panels you can continue to use them without any issue for more than 25 years. To put your mind at ease studies have proven solar panels can last anywhere between 25 to 30 years or sometimes more. 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.
