A 2023 Nature Physics article estimated that between 54 and 160 million tonnes of solar panels will go to waste between 2016 and 2050, depending on how long solar panels stay in use – if they last longer, they'll generate less waste 2.

How do solar panels reduce waste?

In regards to solar panels, innovation in their construction may also place a role in the type of waste they produce. Advancing technology will be vital to decreasing the impact of renewable energy waste. For example, new panels use less silicon, and the manufacturing process produces less waste.

Why is solar panel waste a problem?

The biggest problem with solar panel waste may be its large quantity. Because sunlight is dilute and diffuse, large collectors are required to capture and convert the sun's rays into electricity. Those large surface areas require an order of magnitude more materials (glass, heavy metals, and rare earth elements) than other energy sources.
