Solar Panel Recycling in Washington: What Businesses Need to Know Right Now
Washington was the first state in the country to pass a law requiring solar panel manufacturers to fund the recycling of their products. It's a good headline, but if your business has solar panels reaching end of life today, that law doesn't help you yet, and it's worth understanding why.
The Manufacturer Program Isn't Active Yet
Washington's Photovoltaic Module Stewardship and Takeback Program was first passed in 2017, requiring manufacturers to eventually finance and manage a statewide recycling system for panels sold in the state. But implementation has been delayed more than once. Under the most recent legislative update, manufacturers now have until January 31, 2030 to even submit their stewardship plans to the Department of Ecology for approval.
In plain terms: the system this law creates isn't operational, and won't be for several more years.
What That Means If You Have Panels to Remove Now
Businesses replacing solar arrays, decommissioning a site, or dealing with storm or fire-damaged panels can't wait for a manufacturer program that doesn't exist yet. Washington's Department of Ecology treats end-of-life solar panels as a designated waste stream in the meantime, and specific rules already apply:
Panels can only be accumulated on-site for up to 180 days before they must be moved to a recycling or disposal facility.
If you don't recycle them, you may be required to test and designate them as dangerous waste, since solar panels contain materials like lead, cadmium, or other regulated substances depending on panel type.
Manufacturer takeback isn't a current option for most panel brands, since stewardship plans aren't due for years, businesses need a recycling partner now, not a future government program.
Why This Catches Businesses Off Guard
Most businesses assume that because Washington has a well-publicized solar recycling law, there's already a straightforward system in place. The reality is the opposite: a business decommissioning panels this year is essentially on its own for compliance, working with commercial recyclers directly rather than through a manufacturer channel.
That gap creates real risk. Storing panels indefinitely past the 180-day window, or assuming standard e-waste handling covers solar modules, can put a business out of compliance without anyone realizing it until an audit or inspection.
What to Do If You're Decommissioning Solar Panels
Don't wait on manufacturer programs. They aren't required to exist yet for most brands.
Track your accumulation start date. The 180-day clock starts as soon as panels are removed from service.
Work with a recycler equipped to handle solar materials, not just standard e-waste, since testing and material recovery differ from electronics recycling.
Get documentation. Certificates of recycling or waste designation protect your business if compliance is ever questioned.
How Ecolights Can Help
As Washington's solar fleet ages and more panels reach end of life, we're expanding our recycling capabilities to help businesses navigate exactly this gap, compliant handling today, without waiting on a manufacturer system that's still years from taking effect. If you have panels coming down, reach out before you're staring down that 180-day deadline.
