Oregon Just Passed a Solar Consumer Protection Law: Here's What It Means for Homeowners

Shopping for solar in Oregon just got a little safer. On March 5, 2026, Oregon passed House Bill 4029, a solar consumer protection law that sets new standards for how solar companies must sell and install systems in the state. All Oregon solar contractors have until June 5, 2026 to comply.

If you're a homeowner considering solar, this law is worth understanding. It's designed to protect you from the kind of high-pressure, misleading sales tactics that have given parts of the solar industry a bad reputation.

What HB 4029 Requires of Solar Companies

The new law covers a broad range of practices that directly affect you as a buyer:

Deceptive sales practices are now explicitly prohibited. Solar companies can't misrepresent savings, incentives, or system performance to close a deal.

Licensing requirements are clarified for anyone selling or installing solar and battery storage systems in Oregon.

Disclosure requirements mean that before you sign anything, a solar company must provide you with a specific set of written disclosures, and you have to sign off on them.

Installation contract requirements set minimum standards for what your contract must include, so there are no surprises after the paperwork is done.

Contract cancellation rights give you the ability to back out within a defined window after signing,an important protection if you feel pressured.

Warranty transfer requirements ensure that if you sell your home, your solar warranty can move with it.

What This Means If You're Choosing a Solar Company

HB 4029 sets a floor, a minimum standard every Oregon solar contractor must now meet. But the best solar companies in Oregon have been operating well above that standard all along.At National Solar, none of this is new territory. With 17+ years of installations across Oregon, 3,500+ completed projects, and consistently highly rated reviews, we've built our reputation on the kind of transparency and customer experience that HB 4029 is now requiring of the industry. We stay current on every regulatory update, including this one, because our customers deserve to know exactly what they're signing, what they're getting, and what their rights are.

The companies this law is designed to rein in are the ones that give solar a bad name. National Solar isn't one of them, and our reviews reflect that.

If you're evaluating solar companies, use HB 4029 as a checklist. Ask any contractor you're speaking with how they handle disclosures, what your cancellation window is, and what happens to your warranty if you sell your home. A company worth hiring will answer every one of those questions without hesitation.
