How Long Does Solar Contract Cancellation Take in California? The Deadlines You Can Count On, and the Ones Nobody Can Promise

How Long Does Solar Contract Cancellation Take in California? The Deadlines You Can Count On, and the Ones Nobody Can Promise

It's the first question almost everyone asks, and it deserves an honest answer: it depends on how you're getting out. Inside the cancellation window, it's a matter of days and weeks. For a contract that's already past that window, no one can give you a reliable number, and anyone who does is guessing.



Here's what's actually fixed by law, what isn't, and how to plan around both.

Path one: you're inside the cancellation window

The right to cancel is the one part of this with hard deadlines.

• Contracts signed on or after January 1, 2026: under SB 784, the window is five business days, or seven for homeowners 65 or older, according to the bill text.
• Contracts signed before that date: three business days, or five for homeowners 65 or older.

Your own cancellation notice states the deadline that applies to you, so check it. Our SB 784 guide and cooling-off rule guide explain how the windows work, and why a missing or incorrect notice can matter.

The clocks that start after you cancel

Once you cancel, several deadlines start running on the other side:

• The refund: 10 days. California's Home Solicitation Sales Act says the seller must return your payments and any note within 10 days after cancellation, and the FTC's Cooling-Off Rule says 10 business days. See what the company owes you after you cancel.
• The goods: 20 days. If the seller doesn't demand delivered goods within 20 days, they generally become yours without obligation.
• A lien filing: 20 days after your demand. Under UCC §9-513, a secured party must file a termination for consumer goods within one month after no obligation remains, or within 20 days after receiving your signed demand, whichever comes first.
• A credit dispute: usually 30 days. The CFPB says credit bureaus and the companies that report to them must investigate and fix errors, usually within 30 days. See what cancellation does to your credit.
• A CFPB complaint: 15 days, then up to 60. The CFPB says the company generally responds within 15 days, and if its response isn't final, it has up to 60 days to give a final one. See how the CFPB complaint process works.

An illustrative calendar

This is an example, not a promise, and counting rules vary by contract. Suppose you sign on Monday, March 2, 2026, under SB 784, and mail your cancellation notice on Friday, March 6.

• March 6: You send the notice and keep proof of delivery.
• About March 16: The 10-day refund and security-interest deadline passes. You follow up in writing the next day if nothing has happened.
• About March 26: The 20-day goods deadline passes.
• About April 5: A written UCC demand sent on March 16 would come due.
• Mid-April to mid-May: You check your credit reports 30 to 60 days after the cancellation to confirm nothing is being reported.

Path two: the contract is past the window

For a contract that's already outside its cancellation window, there is no clock. That doesn't mean it's hopeless. It means how long it takes depends on things that vary from case to case, and I couldn't find a published standard timeline from any agency or lender for these:

• Who holds the contract. A lender, a lessor, or a successor after a sale or bankruptcy each responds differently. See our lender and servicer lookup guide.
• What the documents show. A complete file moves faster than a missing one. Our documentation checklist covers what to gather.
• Whether there's an arbitration clause. Enforcing or challenging one adds a separate fight. See what West v. Solar Mosaic decided and our guide to arbitration clauses.
• Whether the signature is disputed. A question about who signed is its own track. See Jones v. Solgen Construction.
• Whether the installer is gone. A bankruptcy or closure changes who you deal with. See our guides to Freedom Forever and Titan Solar Power.
• Whether the other side negotiates. Some disputes resolve in a call, and some don't resolve without a hearing.
• Which route you take. A complaint, a demand, arbitration, and a lawsuit each run on their own timeline. Our complaint agencies guide covers the options.

What speeds things up

• Acting inside the window, while the deadlines work in your favor.
• Having your contract, proposal, statements, and messages ready before you start.
• Sending notices and demands in writing, with proof of delivery.
• Knowing who actually holds the contract, so you aren't addressing the wrong company.
• Following up on the day after each deadline instead of waiting.

What slows things down

• Missing paperwork, especially the original contract and proposal.
• A change of lender or servicer, or an installer that has closed.
• Verbal promises with nothing in writing. CSLB's data shows "insufficient evidence" is the most common reason complaints are closed. See what you can do after an installer fails.
• Waiting. Deadlines and evidence both get harder to meet over time.

What no one can promise you

Not every solar contract can be canceled, and no one can promise a timeline for one that's past its window. What you can do is learn which path applies to you and which clocks are already running. Our solar loan cancellation page explains how we approach financed contracts.

Questions about the timeline

What if the company misses the 10-day refund deadline?

Follow up in writing the next day, document it, and consider a complaint. A missed deadline may mean the company violated the rules.

Will filing a complaint speed things up?

A CFPB complaint creates a tracked company response, generally within 15 days and up to 60, but it doesn't guarantee a resolution.

Is there a deadline to dispute a solar contract after I've signed?

Time limits depend on the claim and on when you discovered the problem, and a transfer of the loan usually doesn't reset them. Don't wait to find out where you stand.

Not sure which path applies to you, or how long yours might take?

Send us your contract, your cancellation notice if you've sent one, and your latest statement and we'll tell you which deadlines are running and what to do next, usually in one 15-minute call.
