Only 10% of solar panels are recycled, and homeowners have no idea their panels contain toxic materials or how to dispose of them legally

The United States is projected to accumulate up to one million tons of solar panel waste by 2030, yet only about 10% of decommissioned panels are currently recycled. The rest are dumped in landfills, burned, or piled in open lots. Solar panels contain small amounts of lead, cadmium, and other heavy metals that can leach into groundwater when panels crack or degrade in landfills. Some panels fail the EPA's Toxicity Characteristic Leaching Procedure (TCLP) test, which means they legally qualify as hazardous waste -- but homeowners removing old panels from their roof have no idea whether their specific panels are hazardous or not, and there's no easy way to find out. This matters because the first massive wave of residential solar installations from the 2010-2015 boom is approaching the 15-20 year mark where panels start failing, degrading significantly, or getting replaced during roof work. A homeowner who needs to reroof their house must pay to have the panels removed ($1,500-$3,000), stored during roofing, and reinstalled -- or dispose of them. If they choose disposal, they can't just put solar panels on the curb. In most jurisdictions, there are no clear disposal guidelines, few local recycling facilities that accept panels, and the cost to properly recycle a panel ($15-$45 per panel, or $300-$900 for a typical system) falls entirely on the homeowner. Many homeowners, unaware of the toxic material content and facing confusing disposal rules, simply throw panels in the dumpster with their construction debris, creating an environmental liability. This problem persists because the solar industry externalized end-of-life costs from the beginning. Unlike the EU, which requires manufacturers to fund panel recycling through Extended Producer Responsibility (EPR) programs, the United States has no federal recycling mandate for solar panels. Only Washington State has an EPR law for solar modules. The EPA is planning to propose adding solar panels to universal waste regulations in 2025-2026, but a final rule isn't expected until late 2026 at the earliest. There are only a handful of specialized solar recycling facilities in the entire country, and the economics of recycling don't yet support the volumes needed. The recovered materials (silicon, silver, aluminum, copper) don't cover the cost of disassembly and processing, so there's no market incentive to build recycling infrastructure ahead of the waste wave.
