Washington state combines strong clean energy commitments with one of the most powerful consumer protection statutes in the country. The Evergreen State's Consumer Protection Act provides for treble damages and attorney's fees, making it a particularly favorable jurisdiction for consumers who have been misled by solar companies. This guide covers the key Washington laws affecting solar consumers, your cancellation rights, and your options if you need to exit a solar contract.
If you signed a solar contract in Washington through a door-to-door or in-home sales transaction, you generally have a right to cancel within a limited window under federal and state law.
The FTC's Cooling-Off Rule (16 CFR Part 429) provides a 3-business-day right to cancel for sales made at your home. This applies to most door-to-door solar sales where a representative visited your residence. The cancellation window extends until midnight of the third business day after signing.
Washington's consumer protection framework includes specific provisions for door-to-door sales. Under Washington law, sellers engaged in home solicitation sales must comply with cancellation notice requirements. The seller is generally required to:
Key detail: If the solar company did not provide the required cancellation notice under Washington law, the cancellation period may not have started running. Given the strength of Washington's Consumer Protection Act, this can be a particularly powerful argument. Consult a Washington-licensed attorney to evaluate your specific situation.
Washington's door-to-door sales protections generally apply to consumer transactions solicited at a buyer's home. This typically includes:
Sales completed at the seller's permanent business location or transactions initiated entirely by the buyer may not be covered. However, many solar contracts involve in-home elements regardless of how initial contact was made.
Time-sensitive: If you are within the cooling-off period, send a written cancellation notice immediately via certified mail with return receipt requested. Do not rely on phone calls or verbal promises to cancel. Pre-installation cancellation guide →
The Washington Consumer Protection Act (CPA) is widely regarded as one of the strongest consumer protection statutes in the nation. Under RCW 19.86.020, it prohibits unfair or deceptive acts or practices in the conduct of trade or commerce. In the solar context, violations may include:
The Washington CPA provides for treble damages (up to three times actual damages), attorney's fees, and costs of suit for prevailing consumers. This combination makes the Washington CPA one of the most powerful consumer protection tools in any state and provides extraordinary leverage for consumers pursuing solar contract disputes.
In our assessment, Washington's Consumer Protection Act is among the strongest in the country for solar consumers. The treble damages and attorney's fees provisions mean that even modest actual damages can result in significant recovery, and the availability of attorney's fees makes it economically viable for attorneys to take on these cases.
The Washington AG's Consumer Protection Division is one of the most active consumer protection agencies in the nation. The division investigates complaints, brings enforcement actions, and has significant experience with home improvement and energy-related consumer complaints. Filing a complaint creates an official record and may trigger investigation or enforcement action.
Washington has strict contractor registration requirements under the Contractor Registration Act (RCW 18.27). Key requirements:
The ability to void contracts with unregistered contractors under RCW 18.27.080 is a particularly powerful tool for Washington homeowners whose solar installations were performed by unregistered companies.
Washington's net metering law (RCW 80.60) requires utilities with 25,000 or more customers to make net metering available to customers who generate electricity using solar or other renewable resources.
Puget Sound Energy and other IOUs offer net metering under RCW 80.60. Excess generation credits are applied to future bills. The Washington UTC oversees rate structures and program terms for regulated utilities.
Washington's many public utilities (including Seattle City Light and Tacoma Power) also offer net metering programs. Terms vary by utility. Some public utilities have been early adopters of favorable solar programs.
Washington's net metering program has capacity limits that have been expanded over time. The specific rates and terms depend on your utility and when you interconnected. Check with your utility for current program details.
The Washington UTC regulates investor-owned utilities, including Puget Sound Energy, Avista, and PacifiCorp. The UTC sets net metering rates, interconnection standards, and other policies affecting residential solar for regulated utilities. Public utilities are regulated by their own governing boards.
Washington's Clean Energy Transformation Act (RCW 19.405) requires all electric utilities to be carbon-neutral by 2030 and to use 100% clean electricity by 2045. This legislation supports the overall solar market in Washington and may affect utility solar programs and incentives over time.
Washington allows various forms of third-party solar ownership. The regulatory treatment of solar leases and PPAs depends on how they are structured and whether they are classified as the sale of electricity. Washington's consumer protection laws apply broadly to these transactions. If you have a third-party solar arrangement, consult a Washington attorney about the specific legal framework applicable to your agreement.
Washington law (RCW 64.38.055) restricts HOAs from prohibiting solar energy installations. Under this provision, HOA rules that effectively prevent solar installations are generally unenforceable. HOAs may adopt reasonable restrictions regarding placement and aesthetics, but cannot prohibit solar panels outright.
Washington has offered various solar incentives over the years, including sales tax exemptions for solar equipment and production-based incentives. The availability and terms of these programs have changed over time. These incentives are relevant to the overall economics of solar in Washington and may have been part of the sales pitch for your system.
Based on our research, the most common solar contract disputes in Washington typically involve these issues:
Washington's cloudy climate, particularly west of the Cascades in the Puget Sound region, means solar production can be significantly lower than in sunbelt states. Some solar companies have used savings projections that do not adequately account for Washington's weather patterns, leading to significant shortfalls. If specific savings were promised, this may constitute a deceptive practice under the CPA.
Some solar companies operating in Washington have marketed leases and PPAs as "free solar panels" or falsely implied government subsidies that eliminate all costs. These misrepresentations are particularly actionable under Washington's strong CPA, which provides treble damages and attorney's fees for deceptive practices.
Solar leases and PPAs in Washington may result in UCC-1 financing statements filed with the Washington Secretary of State's office. These can complicate home sales and refinancing in Washington's competitive real estate markets. Many homeowners report being unaware of these filings before signing. UCC lien removal guide →
Washington's contractor registration requirements are strict, and some solar installations have been performed by unregistered contractors. Under RCW 18.27.080, contracts with unregistered contractors are voidable at the homeowner's option — a powerful tool for contract rescission that is not available in many other states.
Washington's wet climate places additional demands on solar installations, particularly regarding waterproofing and roof penetrations. Some homeowners have experienced roof leaks, moisture damage, and other installation quality issues. Performance guarantees should be carefully reviewed and enforced.

Read your entire solar agreement, including all exhibits, addendums, and fine print. Identify the type of agreement (lease, PPA, or loan), the cancellation provisions, buyout terms, escalator clauses, and any performance guarantees. Note the company name and all critical deadlines.

Gather all documentation related to your solar purchase:
Washington is a two-party consent state for recording phone calls (RCW 9.73.030). You generally need the consent of all parties to legally record a phone conversation. Focus on written documentation and take detailed notes of phone conversations instead.
