Solar Contract Cancellation: Find Your Deadline Today
United States only. This page states no cancellation period, cites no statute and gives no legal advice. It is a routing page, and the sections are in the order to act on them.
If you signed recently and want out, the only number that matters is your deadline, and this page cannot tell you what it is. It can tell you exactly who can, in under an hour, for free.
Stop reading and do the first section now if this is urgent. Everything after it is background.
Do this in the next hour
1. Find the contract. Every page of it, including anything you signed on a tablet. If you do not have a copy, that in itself is worth telling the office you call in step 3.
2. Find the cancellation section and read it. Home-solicited sales contracts commonly must contain a notice of the right to cancel, stating the deadline and the method. Read the method carefully. Written notice, to a specific address, by a specific date is a typical form, and a phone call to the salesperson is typically not sufficient however reasonable it feels.
3. Call your state attorney general's office or consumer protection division. Ask: what cancellation right applies to a residential solar contract signed at my home on this date, in this state, and by what method and deadline must I exercise it?
This is the call that answers your question. It is free, it is what the office exists for, and the answer is authoritative in a way nothing on the internet is.
4. If you are cancelling, do it in writing, by the method the contract specifies, and keep proof. Certified mail, a delivery receipt, a saved email with a timestamp. The proof is what matters if there is a dispute later.
5. Do not wait for the company to respond before considering yourself to have cancelled. The deadline runs against the calendar, not against their inbox.
6. If the window has already passed, that is an attorney's question and not a solar site's. Many consumer law attorneys assess this kind of matter at no initial cost, and your state bar association can refer you.
Why this page will not print a number
Not caution for its own sake. Four specific reasons.
Cancellation rights come from more than one place. Federal rules cover certain sales made at a consumer's home, and states have their own home-solicitation and home-improvement statutes, which can be more generous and can attach different conditions.
They depend on facts about your transaction. Where you signed, who initiated the contact, what kind of agreement it is, whether the required notice was given, and whether the notice was correct.
They differ by state, and this site's state footprint is currently an accident of which statute servers were reachable on the day. That is recorded honestly in this site's own planning: three states appear in an existing article because their sources responded and one is absent because its server refused the connection twice. We are not going to compound that by generalizing.
And a wrong number here would be the most damaging error this site could make. A reader who reads a longer period than they actually have loses their right by waiting.
The office that knows your answer will tell you today. Use it.
What cancellation is, and what it is not
Useful to have straight before you call.

A statutory cancellation right is a defined window during which a contract can be undone, usually with the goods returned or the work stopped and money returned. It is a creature of statute and it is short.
It is not the same as a general right to change your mind, which does not exist for most contracts.
It is not the same as disputing performance later. A company that installs badly is a different problem with different remedies.
And it is not the same as walking away from financing. If a loan, lease or power purchase agreement was signed alongside the installation contract, that is potentially a separate agreement with a separate cancellation position, and it is one of the things to ask about specifically. Ask the question as: what happens to the financing agreement if I cancel the installation contract?
What makes this harder than it should be
Three structural features of solar sales that complicate the picture, and they are worth knowing so you ask about them.
Multiple entities. The company that sold, the company that installs and the company that finances are frequently three different parties, which means potentially more than one agreement and more than one cancellation position. Ask specifically which agreements you signed and with whom.
Electronic signature at speed. A stack of documents signed on a tablet in one sitting is still a stack of documents. Ask for complete copies of everything.
Work starting quickly. Some companies move fast on permitting or equipment ordering. What has already happened can affect what unwinding looks like, which is another reason speed matters and another question for the office you call.
Preventing the situation entirely
The general form of every point above is that the pressure to sign quickly is the problem.
Do not sign at the door or on the day. The reliable warning signs in a solar sale are about process rather than product, and the compression of your decision into a single visit is the one that produces regret.
Get three quotes and compare them properly. Reading three proposals side by side takes an evening and it is the step that most reliably prevents this whole article being relevant to you.
Read the financing separately from the installation. They are separate commitments even when they arrive in one envelope, and what the total financing actually costs is frequently obscured by a monthly payment.
And decide whether solar makes sense for you at all before anybody quotes, on your own electricity rate and your own roof.
Who to contact, in one list
- Your state attorney general's office or consumer protection division. The cancellation question. First call, always.
- Your state contractor licensing board. If the company is licensed, and to file a complaint about its conduct.
- A consumer law attorney, if the window has passed or the company disputes a valid cancellation. Your state bar association runs referral services.
- Your state's utility commission, if the dispute involves the utility agreement or the tariff rather than the sale.
- Your lender, separately, about the financing agreement.
FAQ
How many days do I have to cancel a solar contract? This page does not state a period, and that refusal is deliberate. Cancellation rights come from federal rules and from state home-solicitation and home-improvement statutes, they differ, and they depend on facts about your own transaction, including where you signed, who initiated the contact, what kind of agreement it is and whether the required notice was given and was correct. A reader who acts on a longer period than they actually have loses the right by waiting. Your state attorney general's office or consumer protection division will tell you the applicable deadline and method today, for free.
Is telling the salesperson I have changed my mind enough to cancel? Typically not, however reasonable it feels. Home-solicited sales contracts commonly must carry a notice of the right to cancel that states both the deadline and the method, and written notice to a specific address by a specific date is a typical form. Cancel in writing by the method the contract specifies and keep proof of sending, such as certified mail, a delivery receipt or a saved email with a timestamp. The proof is what matters if there is a dispute later. Do not wait for the company to reply before considering yourself to have cancelled, because the deadline runs against the calendar rather than their inbox.
If I cancel the installation contract, does the financing go away too? Do not assume so. A loan, lease or power purchase agreement signed alongside the installation contract is potentially a separate agreement with its own cancellation position, and in solar the seller, the installer and the finance company are frequently three different parties. Ask which agreements you signed and with whom, ask the question directly as what happens to the financing agreement if I cancel the installation contract, and speak to your lender separately.
What if the cancellation window has already passed? That is an attorney's question rather than one for a solar site, and this page does not answer it. Many consumer law attorneys assess this kind of matter at no initial cost, and your state bar association runs a referral service. Your state contractor licensing board is also where a complaint about the company's conduct belongs, and your state utility commission handles a dispute that is about the utility agreement or the tariff rather than the sale.
How do I avoid needing this page at all? Do not sign at the door or on the day. The warning signs in a solar sale are about process rather than product, and the compression of your decision into a single visit is what produces regret. Get three written quotes and compare them side by side, read the financing separately from the installation even when they arrive in one envelope, and settle whether solar makes sense on your own electricity rate and your own roof before anybody quotes.
The short version
Cancellation rights are real, short and set at federal and state level, and they depend on facts about your own transaction. Find the contract, read its cancellation section, and call your state attorney general's office today for the deadline and the method. Cancel in writing by the specified method and keep proof of sending. Ask separately what happens to any financing agreement. And if the window has passed, that is an attorney's question, not a question this or any other solar site can answer.
