Solar panels – an eco-disaster waiting to happen?
While they are being promoted around the world as a crucial weapon in reducing carbon emissions, solar panels have an average lifespan of 25-30 years.
Experts say billions of panels will eventually all need to be disposed of and replaced.
“The world has installed more than one terawatt of solar capacity. Ordinary solar panels have a capacity of about 400W, so if you count both rooftops and solar farms, there could be as many as 2.5 billion solar panels.,” says Dr Rong Deng, an expert in solar panel recycling at the University of New South Wales in Australia.
