What happens to solar panels once their lifespan is up?

Modern solar panels are built to last for 25 years or more - and the good news is, when your panels eventually stop working they can be recycled with around 80-100% efficiency, since the silicon, metal and glass can be processed and re-purposed.

There are already dozens of solar panel recycling facilities out there, and some manufacturers will even recycle them for you free of charge.
