Washington Solar Panel Recycling: Get Ahead of RCW 70A.510
Washington's manufacturer take-back law kicks in between 2030 and 2031. Contractors who document their chain of custody now will be ready when compliance becomes mandatory — and will have the audit trail to prove it.
See how Sunpliance documents WA jobsWhat the Law Requires
RCW 70A.510 (formerly ESSB 5939) is enacted and in active rulemaking — WAC 173-905 is currently finalizing fee structures
Manufacturers must submit stewardship plans to the Department of Ecology by January 31, 2030
From January 31, 2031, solar modules cannot be sold in Washington unless the manufacturer has an approved plan
Stewardship plans must demonstrate collection infrastructure, transport logistics, and an 85% recycling rate target
Penalties of up to $10,000 per sale apply to manufacturers operating without an approved plan
Contractors and system owners are not directly penalized today — but panels sold post-2017 fall under the eventual take-back obligation
Who Is Responsible
Washington takes a different approach from New Jersey and California. Under the EPR model in RCW 70A.510, manufacturers — not installers or system owners — bear the primary legal and financial obligation to fund collection and recycling programs.
That said, contractors who document chain of custody now are in a stronger position when the mandate is fully active. If a manufacturer's take-back program is operational and a contractor cannot produce job records showing where panels went, disputes over compliance responsibility become harder to resolve.
The practical advice: treat Washington jobs the same way you treat NJ and CA jobs. The paperwork habit you build now is the proof you need later.
What Washington Will Require — and What to Track Now
Washington's stewardship program is not yet active, but the regulatory framework is in place. When manufacturer take-back programs launch, contractors will need to show panels reached an approved collection point. The records to build now are:
- Panel origin and system owner identity at time of removal
- Date of removal and removing contractor identity
- Transporter and chain of custody through each handoff
- Destination facility — and whether it will qualify as an approved collection point under the stewardship plan
- Any TCLP test results if panels are managed as Universal Waste
Sunpliance builds the full chain-of-custody record on every job — so when Washington's program activates, your documentation is already there.
How Sunpliance Handles Washington Compliance
Panel capture at removal with AI-assisted serial and manufacturer extraction
Every handoff recorded — removal, transport, destination facility
Records retained 7 years by default — well beyond any expected Washington retention requirement

Frequently asked questions
Is Washington's solar recycling law currently enforced?+
The law is enacted but the take-back program is not yet active. Manufacturer stewardship plans are due January 31, 2030. Contractors are not directly penalized today, but the framework is in place.
Who pays for Washington's take-back program?+
Manufacturers fund the collection and recycling programs under the EPR model — not installers or system owners. However, contractors are responsible for ensuring panels reach an approved collection point.
What is the 85% recycling rate target?+
Stewardship plans submitted to the Department of Ecology must demonstrate how at least 85% of collected panel mass will be recycled, not landfilled or incinerated.
What happens if a manufacturer doesn't have an approved plan by 2031?+
Their modules cannot legally be sold in Washington, and they face penalties of up to $10,000 per sale.
Should Washington contractors document jobs now even though enforcement hasn't started?+
Yes. The chain-of-custody records you build today are the evidence you produce when the program activates. Sunpliance retains all records for 7 years by default.
