Boom period About Solar Panel

The new ROSI plant will open during a boom period for solar panel installations.

The world's solar energy generation capacity grew by 22% in 2021. Around 13,000 photovoltaic (PV) solar panels are fitted in the UK every month - most of them on the roofs of private houses.

In many cases, solar units become relatively uneconomical before they reach the end of their expected lifespan. New, more efficient designs evolve at regular intervals, meaning it can prove cheaper to replace solar panels that are only 10 or 15 years old with updated versions.

If current growth trends are sustained, Ms Collier says, the volume of scrap solar panels could be huge.

"By 2030, we think we're going to have four million tonnes [of scrap] - which is still manageable - but by 2050, we could end up with more than 200 million tonnes globally."

To put that into perspective, the world currently produces a total of 400 million tonnes of plastic every year.
