The short answer: Under the FTC Cooling-Off Rule, 16 CFR Part 429, you can cancel covered sales made at your home within three business days, and some states give more time. Sign and send a written notice, ideally by certified mail, to the address on your Notice of Cancellation form, and keep proof. The seller must honor a valid cancellation within 10 business days.
Key takeaways
- You generally have at least three business days.
- Some states give five or more.
- Use certified mail and keep proof.
- You don't need to give a reason.
- Send a copy to any separate lender.

Solar Cancellation HQ is not a law firm and does not provide legal advice. This page is general information, and reading it or submitting a form does not create an attorney-client relationship. Not every contract qualifies, and no outcome is guaranteed. We never advise anyone to stop making payments on a solar loan, lease or PPA. Laws and utility rules change, so verify before acting.
