As awareness about clean energy grows, solar power has become increasingly popular. Once installed, solar panels can fulfill a household’s energy needs for the next three decades. However, as the first generation of solar panels nears the end of their lifespan, the issue of solar waste has emerged.

Solar panels contain hazardous materials such as lead, cadmium, and other toxic chemicals, which can be harmful to human health and the environment if not disposed of properly. It is estimated that by 2050, solar panels will contribute around 80 million metric tons of waste. The good news is that most components used in solar panel manufacturing are recyclable.

According to the International Renewable Energy Agency (IRENA), 80% of the components in solar modules, including glass and metal frames, can be recycled. Pilot initiatives around the world have shown that existing recycling practices in the glass, metals, and electronics industries can accommodate solar panels and other solar power system components. Additionally, the recovered silicon from recycled panels can be used to manufacture new solar cells and electronic components.

A recent study by researchers at the Indian Institute of Technology (IIT) Mandi has proposed industrial solutions for effectively recycling solar cell components and materials. The study demonstrated that recycling these materials significantly reduces the environmental impact compared to conventional mining and production practices. Recycling also enables the recovery of valuable resources like cadmium, tellurium, indium, gallium, and germanium, which are in high demand and have limited reserves.

To manage the issue of solar waste, the Ministry of Environment, Forest and Climate Change in India has notified the inclusion of solar photovoltaic modules, panels, and cells under the E-Waste (Management) Rules, 2022. Manufacturers and producers are required to register on the government’s portal and store the waste generated until 2034-2035.

Addressing the environmental challenge of solar waste requires a comprehensive understanding of reuse, repurposing, recycling, and recovery of valuable resources. By adopting proper recycling practices, we can mitigate the negative impact of solar waste and create a more sustainable solar power industry for the future.
