Concerning the photovoltaic module stewardship and takeback program.

Washington State's HB 1789 establishes a program requiring solar panel (photovoltaic module) manufacturers to finance and manage recycling and takeback systems for their products. The bill directly affects manufacturers, distributors, and retailers of solar panels sold in Washington, mandating they create and submit "stewardship plans" by January 31, 2028. Key provisions include requiring manufacturers to cover all costs for collection and recycling, accept all panels sold in the state since 2017, minimize hazardous waste, and recover valuable materials like rare earth elements. The program aims to ensure convenient, safe, and environmentally sound end-of-life handling of solar panels without cost to consumers.
