6 FAQs about [Waste from solar energy]

Are solar panels causing waste?

The growth of solar energy over the years has generated millions of tonnes of panel waste that usually end up in landfills. But some companies in the US have started to tackle this issue. Maintaining efficiency requires renewing solar cells, creating waste. Credit: Kampan via Shutterstock.

How can solar panels reduce waste?

The solar industry is taking a variety of steps to reduce waste and concerns about toxicity by extending the lifespan of panels, finding alternatives for certain materials and working on efficient ways to recycle panel components. The hope is that these efforts will mean that the actual amount of waste will be less than current estimates.

Should solar panel waste be increased?

Concerns about an increase in solar panel waste need to be placed in the context of how the amount of waste compares to other sources.

How much will solar panel waste cost the world?

According to the EPA, the total value of the recoverable raw materials from solar panel waste globally will reach about $450m by 2030, almost equivalent to the cost of raw materials needed to produce nearly 60 million new panels.

How much will solar waste be recycled by 2050?

By 2050, solar waste will total some 78 million tons globally, said Mool Gupta, a professor in the Department of Electrical and Computer Engineering at University of Virginia. The reason recycling and recovery isn’t robust yet, Gupta said, is that companies struggle to justify the $30 per panel cost when it costs only $1 to send it to a landfill.

Why are there so few facilities for recycling solar panels?

The reason there are so few facilities for recycling solar panels is because there has not been much waste to process and reuse until recently. The first generation of domestic solar panels is only now coming to the end of its usable life. With those units now approaching retirement, experts say urgent action is needed.
