BackgroundAre Solar Panels Hazardous Waste?Overview of Hazardous Waste RegulationsState Solar Panel End-Of Life PoliciesAdditional ResourcesSolar panels provide clean, renewable energy from the sun, and their prevalence as an energy source has been growing. In 2020, solar panels provided about 40 percent of new U.S. electric generation capacity, compared to just four percent in 2010. Overall, 3.3 percent of electricity in the United States was produced using solar technologies in 202See more on epa.govIEA – International Energy Agency
