Full answer body

Expanded summary

While there are worries about toxic waste from decommissioning solar panels, research from the National Renewable Energy Laboratory (NREL) suggests these concerns may be exaggerated. Some sources claim solar panels produce more toxic waste per unit of energy than nuclear power, but the NREL researchers argue against this. There is a debate over the environmental impact of solar panel disposal, with some advocating for proper recycling programs to mitigate potential risks. However, the current economic and technical feasibility of widespread solar panel recycling remains a challenge.
