How to Cancel a Solar Contract in California (2026)

California has the strongest solar consumer protections in the country — but most homeowners never use them. Here is exactly how to cancel your solar lease or loan in California, with state-specific laws, agencies, and step-by-step actions.

Quick answer

California homeowners can cancel a solar contract within 3 business days under the Home Solicitation Sales Act. After that, cancellation options include breach of contract for underperforming systems, CLRA and UCL claims for deceptive sales, and CPUC complaints for utility-related issues. California's consumer protection laws are among the strongest in the nation and many homeowners have successfully exited solar contracts using them.

Why California Is Different

California leads the nation in residential solar adoption — and in solar complaints. The state is also home to the strongest consumer protection framework for solar homeowners anywhere in the country. If you are a California homeowner trapped in a solar contract, you have more tools than homeowners in almost any other state. The problem is most homeowners do not know they exist.

Your California-Specific Rights

Home Solicitation Sales Act — 3-Day Right to Cancel

California Civil Code § 1689.5 gives you 3 business days to cancel any contract signed in your home following a door-to-door solicitation — with no penalty, no reason required. This is mandatory. If the sales rep did not provide you with a written Notice of Cancellation in the same language the contract was negotiated in, the 3-day window may still be open.

California Consumer Legal Remedies Act (CLRA)

The CLRA prohibits deceptive sales practices and provides strong remedies for consumers. If a solar sales rep misrepresented savings, government subsidies, system performance, or contract terms, you may have a CLRA claim. Remedies include actual damages, punitive damages, injunctive relief, and attorney fees. Before filing suit under the CLRA, you must send a demand letter to the company giving them 30 days to cure.

California Unfair Competition Law (UCL)

The UCL is one of the broadest consumer protection statutes in the country. It covers any unlawful, unfair, or fraudulent business practice. This includes aggressive door-to-door tactics, misleading advertising, and failure to honor warranties. UCL claims can be filed by the AG, DAs, or private parties.

California Public Utilities Commission (CPUC)

The CPUC regulates the solar industry in California and can investigate complaints against solar companies. File complaints at cpuc.ca.gov. The CPUC has taken action against solar companies for deceptive NEM (net energy metering) representations and installation delays.

Contractors State License Board (CSLB)

Solar contractors must be licensed by the CSLB. File complaints at cslb.ca.gov — the CSLB can revoke licenses, require bond claims, and mandate repairs. The CSLB's Contractors' State License Board Arbitration Program provides a low-cost dispute resolution option for claims under $12,500.

The PACE Loan Warning

California has many homeowners who financed solar through PACE loans (Property Assessed Clean Energy) — programs like HERO, CalFirst, and Ygrene. PACE loans attach to your property tax bill, not your credit, and become a senior lien on your home. The FTC and California AG have taken action against PACE lenders for deceptive practices. If you have a PACE loan, you have specific additional rights — and you should consult an attorney familiar with PACE before taking any action.

Top Solar Companies With California Complaints

California homeowners file complaints against every major national installer. Sunrun, based in San Francisco, has thousands of BBB complaints from California customers alone — roof damage from installation, systems that underperformed for years, and lease terms that misrepresented the annual escalator rate. Freedom Forever, founded in California, has similar complaint patterns. SunPower's bankruptcy has left thousands of California homeowners without warranty support despite being the company's home state.

Step-by-Step: Canceling Your California Solar Contract

Read your contract — identify the production guarantee, escalator rate, buyout schedule, and cancellation provisions
Pull your utility bills — compare pre-solar and post-solar to document underperformance
Send a written demand by certified mail — state the specific ways the company has failed to perform and demand remedy or cancellation within 30 days
File simultaneously with: CPUC, CSLB, California AG at oag.ca.gov, and BBB
Send a CLRA demand letter if deceptive sales practices were involved (required 30-day cure period before suit)
Consult a consumer attorney — many take CLRA and UCL cases on contingency because fee-shifting makes them economically viable

The Bottom Line for California Homeowners

You have the most powerful set of consumer protection tools in the country. You also have the largest concentration of solar companies with the worst complaint records. Use the tools. File the complaints. And do not let a solar company convince you that a 25-year lease is inescapable — because in California, with the right approach, it often is not.

Frequently asked questions

What is the 3-day cancellation rule for solar in California?

California Civil Code § 1689.5 gives you 3 business days to cancel any contract signed in your home after a door-to-door solicitation. The company must provide a completed Notice of Cancellation form. If they did not, the window may still be open regardless of when you signed.

How do I file a CPUC complaint against a solar company?

File at cpuc.ca.gov using the online complaint portal. The CPUC handles complaints about solar companies related to utility interconnection, NEM billing, and installation practices. For contractor-specific complaints, file separately with the CSLB at cslb.ca.gov.

What is a PACE solar loan and how is it different?

PACE (Property Assessed Clean Energy) loans attach to your property tax bill rather than your personal credit. They become a senior lien on your home, meaning they are paid before your mortgage in a foreclosure. PACE loans have specific consumer protections in California — consult an attorney if you have one.

Can I sue my solar company in California?

Yes. California's CLRA and UCL provide private rights of action against solar companies for deceptive sales practices. Attorney fee shifting under these laws makes it economically viable for attorneys to take these cases on contingency. Send a CLRA demand letter first, then consult a consumer attorney.

What if my California solar system underperformed for years?

Multi-year underperformance while you are making lease or loan payments may constitute breach of contract and a UCL violation if the production guarantee was not honored. Document every year of production data vs. promised production and consult an attorney about your options.

Who regulates solar companies in California?

Solar companies in California are regulated by the CPUC (utility and NEM issues), the CSLB (contractor licensing), and the California AG (consumer protection under UCL and CLRA). You can file complaints with all three simultaneously.
