Quick Answer: To cancel a solar contract in California, send written notice to the contractor by midnight of the third business day after you received a signed, dated copy of the contract, or the fifth business day if you are 65 or older.
After that window closes, your options depend on the agreement type, the contract terms, and whether the sale followed California’s disclosure and licensing rules.
What California Law Says About Canceling a Solar Contract
California gives homeowners a short, statutory right to cancel most residential solar contracts that were sold at the home or anywhere other than the contractor’s place of business.
That right comes from the home solicitation rules in Civil Code Section 1689.6 and the home improvement contract rules in Business and Professions Code Section 7159. Both laws measure the deadline in business days, not calendar days.
The 3-Day Right to Cancel California Homeowners Receive
The 3-day right to cancel in California lets a buyer cancel a qualifying solar contract for any reason until midnight of the third business day after receiving a signed, dated copy of the contract.
The cancellation can be sent by email, mail, fax, or delivery of a written notice to the contractor’s place of business, and the contract must include a Notice of Cancellation that explains the process.
The 5-Day Rule for Senior Citizens
A buyer who is 65 or older has five business days instead of three. AB 2471 extended the senior citizen cancellation period for contracts signed on or after January 1, 2021, after lawmakers raised concerns about high-pressure sales to older homeowners in their homes.
Many contracts now include separate notices for buyers under 65 and for seniors, so the homeowner should confirm the correct one was provided.
The Disclosure Documents Every Contract Should Include
The Solar Energy System Disclosure Document must be printed on the front page or cover page of every residential solar energy contract in California. The CSLB and the CPUC developed the form under Business and Professions Code Section 7169, and it states the total cost of the system, including financing and energy costs where they apply. A blank copy of the solar disclosure form is available from the CSLB for comparison.
Customers of PG&E, SCE, SDG&E, Liberty Utilities, Bear Valley Electric Service, and PacifiCorp must also sign the California Solar Consumer Protection Guide before the utility will connect a residential solar system to the grid. A missing guide does not automatically void a contract, but it matters when reviewing how the sale was handled.
How Do You Count Business Days in California?
California counts every calendar day as a business day except Sundays and certain listed holidays, including New Year’s Day, Memorial Day, Independence Day, Labor Day, Veterans Day, Thanksgiving, and Christmas. Saturdays generally count. This detail catches many homeowners off guard, because the California solar cancellation period can end sooner than expected.
Here is how the timing works in practice:
| Copy of Contract Received | Buyer Under 65: Deadline | Buyer 65 or Older: Deadline |
| Friday | Midnight Tuesday (Saturday, Monday, Tuesday) | Midnight Thursday |
| Monday | Midnight Thursday | Midnight Saturday |
| Friday before Labor Day | Midnight Wednesday (Monday holiday skipped) | Midnight Friday |
The clock starts when the buyer receives a signed, dated copy of the contract, not necessarily when the buyer signed on a salesperson’s tablet. If no complete copy was delivered, the start date may be later than the homeowner assumes, which is one reason the delivery date should be documented carefully.
How to Cancel a Solar Contract in California Step by Step
The safest way to cancel a solar contract in California during the cooling-off window is to act in writing, act early, and keep proof. The steps below apply to leases, PPAs, loans, and cash purchases sold away from the contractor’s business.
- Find the date you received the contract copy: Check your email inbox, e-signature platform, and paper folder for the first time a signed, dated copy reached you. Count business days forward from that date.
- Locate the Notice of Cancellation: The notice tells you where to send the cancellation and in what form. Use the address and email listed there.
- Write a clear cancellation notice: Include your full name, property address, contract or account number, the date, and one sentence stating that you are canceling the contract. Sign and date it.
- Send it in a way you can prove: Email the notice and also send it by certified mail with return receipt. A mailed notice generally counts when it is sent, so a postmark before the deadline matters.
- Notify the lender separately: If the system was financed, send a copy to the finance company. A solar loan right of rescission under the federal Truth in Lending Act generally applies only to certain loans secured by the principal home, so the loan documents need their own review.
- Stop any scheduled work: Tell the installer in writing not to begin site surveys, permits, or installation.
- Track the refund: Note the date of cancellation and follow up in writing if deposits or payments are not returned as the Notice of Cancellation describes.
What If the Cancellation Window Has Already Passed?
Missing the statutory deadline does not end every option, but it changes the path. A solar contract after installation is governed mainly by its own terms, which means the agreement type matters more than anything else. The table below shows where homeowners usually start.
| Agreement Type | Common Exit Routes After the Window | What to Check First |
| Solar lease | Transfer to a home buyer, buyout, early termination clause | Transfer and assignment terms, buyout schedule |
| Solar PPA | Transfer, prepayment, buyout | Rate escalator, transfer fees, removal clause |
| Solar loan | Payoff, refinance, sale of home with payoff | Prepayment terms, UCC-1 fixture filing, lien position |
| Cash purchase | Warranty or defect claims, contract dispute | Workmanship warranty, production guarantee |
| PACE financing | Payoff of the assessment | Assessment contract, property tax bill |
Solar lease cancellation California homeowners pursue often turns on the transfer and buyout clauses, and the realistic paths for exiting a solar lease are usually different from those for a loan. Homeowners who want to cancel solar PPA California agreements should look closely at the annual rate escalator, because the escalator affects both the buyout price and how easily a future buyer accepts the transfer.
When the Sale Itself May Be the Problem
Some contracts can be challenged because of how they were sold rather than what they say.
Common issues include a missing or defective Notice of Cancellation, which can affect the cancellation timeline in some cases, a contract written in a different language than the sales presentation, a signature the homeowner did not provide, an unlicensed salesperson or contractor, and misrepresentation about savings, tax credits, or “free” solar.
None of these issues guarantees an exit, but each one can change the homeowner’s leverage and should be documented.
Provider-Specific Processes
Large national providers run their own transfer and buyout procedures on top of California law, and the Sunrun cancellation process is a good example of company-specific steps. Homeowners who want to cancel a solar contract in California with a national provider should still start with the provider’s actual agreement.
Where California Homeowners Can File a Complaint
The CSLB handles complaints about solar contractors and home improvement salespeople, and it offers a dedicated CSLB solar complaint form that asks whether the system was a cash purchase, lease, PPA, loan, or PACE project.
The CSLB reported receiving 1,067 solar complaints between July 2019 and June 2020, which led the board to create the separate form.
Complaints about solar financing companies can go to the Department of Financial Protection and Innovation (DFPI). The CSLB has also run a Solar Energy System Restitution Program for certain losses on contracts signed on or after January 1, 2016, but it relied on limited one-time funding, so availability should be confirmed with the CSLB.
Documents to Gather Before You Take Action
A complete file makes every option faster to evaluate, whether the homeowner wants to cancel a solar contract in California within the window or negotiate months later. Gather these items:
- The signed contract, all addenda, and the Notice of Cancellation
- The Solar Energy System Disclosure Document and the signed CPUC guide
- Loan or financing documents, including any UCC-1 fixture filing notice
- Emails, texts, and marketing materials showing promised savings
- Utility bills from before and after installation
- Interconnection approval and any production monitoring reports
- The salesperson’s name and the contractor’s license number
Common Mistakes That Cost Homeowners Options
Small procedural errors often decide whether a cancellation works. These mistakes come up most often:
- Canceling by phone only: A phone call is hard to prove. California’s cancellation process relies on written notice.
- Counting calendar days instead of business days: Saturdays usually count and Sundays do not, which shifts the deadline.
- Canceling the installer but not the lender: The finance agreement may be a separate contract that continues unless addressed.
- Stopping payments without a plan: Missed payments can trigger late fees, default terms, and credit reporting before any dispute is resolved.
- Signing a “replacement” agreement: A new contract offered to fix complaints can reset terms and waive earlier issues.

Frequently Asked Questions About Canceling Solar in California
These are the questions California homeowners ask most often.
Can I cancel a solar contract in California after installation?
Possibly, but not through the 3-day or 5-day cooling-off right once that window has passed. After installation, homeowners usually rely on transfer, buyout, payoff, or a dispute based on misrepresentation or disclosure problems. The specific contract terms decide which route is realistic.
Do Saturdays count toward the cancellation period in California?
Yes, Saturdays generally count as business days under California’s home solicitation rules. Sundays and certain listed holidays do not count. Homeowners should count carefully from the day they received a signed, dated copy of the contract.
Do I have to pay a fee to cancel during the cooling-off period?
No, a valid cancellation within the statutory window should not require a cancellation fee. The contractor is expected to return payments made under the contract as described in the Notice of Cancellation. Keep proof of the cancellation date in case a refund is delayed.
Does canceling the solar contract also cancel my solar loan?
Not always. The solar installation contract and the loan agreement can be separate contracts with separate cancellation terms. Homeowners should send written notice to both the installer and the lender and review the loan documents for any rescission rights.
Can a solar company refuse to cancel my contract?
A solar company may refuse a request that falls outside the statutory window or the contract’s own terms. If a company refuses a timely cancellation, homeowners can file a complaint with the CSLB and keep every record of the notice they sent. A refusal outside the window usually means negotiating under the contract’s transfer or buyout terms instead.
