How long do solar panels last?
Surprisingly, solar panel lifespan has always been extremely good. Given they have no moving parts, there is rarely something that can go wrong within the solar panel itself, which means they can keep generating electricity for a very long time. However, what has improved is the level a solar panel will be performing at after 25 years of usage.
How long do monocrystalline solar panels last?
