Washington state solar panel owners will soon benefit from a more comprehensive, long-term recycling solution thanks to the passage of Senate Bill 5175, a bill focused on strengthening and updating the state’s Photovoltaic (PV) Module Stewardship and Takeback Program.
Boost to Recycling Infrastructure
Originally launched in 2017, the program requires solar panel manufacturers to develop and fund a safe, convenient, and environmentally sound way to recycle panels purchased after July 1, 2017. The latest update pushes key deadlines out to give both manufacturers and the state more time to develop a robust infrastructure for recycling solar modules and preventing harmful materials from ending up in landfills.
Under the new law, solar panel manufacturers now have until January 31, 2030 to submit a stewardship plan to the Washington Department of Ecology. These plans must explain how the company will handle the takeback, transport, and recycling of its panels—at no extra cost to consumers. Starting January 31, 2031, no solar panel can be sold in Washington unless its manufacturer has an approved plan in place.
Get Your Energy Independence
To ensure the recycling system is effective and equitable, the Department of Ecology is tasked with creating a Photovoltaic Module Advisory Committee, which will include voices from tribal communities, environmental groups, local governments, solar manufacturers, labor unions, and utilities. This group will work alongside a consultant to study best practices and environmental justice concerns, with a final set of recommendations due to the Legislature by December 1, 2028.
Consumer Impact
What does this mean for homeowners and solar system owners? While you won’t need to take any action right now, this law lays the groundwork for a future where used solar panels can be easily and responsibly recycled—keeping toxins out of the environment and valuable materials in circulation. It’s a step forward in ensuring that Washington’s clean energy transition remains sustainable from installation through end-of-life.
The bill passed with strong bipartisan support and will go into effect on June 30, 2025.
