How long do solar panels last on roof.

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

These real world experiments will tell us more about how long solar panels last but there is plenty of evidence already to show that solar panels can last 30 years and beyond. However this doesn t mean the panels on your roof will stop producing electricity after a couple of decades. The warranty typically guarantees panels will work above 80 of their rated efficiency after 25 years. Especially because your panels will not stop working after 25 years they just won t work as well.

In reality solar panels can last quite a bit longer than that. This is the industry standard warranty from tier 1 manufacturers. Chances are if you installed a roof top solar system today it would last longer than your roof. As a general solar industry rule of thumb solar panels last about 25 30 years.
