If you need to cancel a solar contract or dispute terms with your solar company, putting your request in writing is essential. A well-crafted solar cancellation letter creates a paper trail, demonstrates your seriousness, and may be legally required to preserve your rights. Based on our research, having the right cancellation letter — sent via the right method — can make the difference between a successful cancellation and months of frustration. Below, we provide three free, professionally drafted solar contract cancellation letter templates you can customize to your situation.

Not every disagreement with a solar company requires a formal letter, but in many situations, a written cancellation or dispute letter is either legally required or strongly advisable. Here are the most common scenarios where homeowners typically need to send a solar cancellation letter:
Under the FTC Cooling-Off Rule, you have 3 business days to cancel any contract resulting from a door-to-door sale — and this includes solar contracts signed in your home after a door-to-door sales visit. Many states extend this period beyond the federal minimum. During this window, you have an unconditional right to cancel for any reason. However, you must exercise this right in writing, and the letter must be sent (not just written) before the deadline expires.
The solar company should have provided you with a cancellation form at the time of signing. If they did not, this may be a violation of federal law that could extend your cancellation rights. Regardless, sending your own cancellation letter in addition to any provided form creates a stronger paper trail.
If you have discovered that the solar salesman lied about savings projections, system performance, contract terms, or financing conditions, a formal dispute letter puts the company on notice and begins the process of seeking resolution. Common post-installation disputes include:
Many solar contracts contain provisions that require disputes to be raised in writing before any formal legal process can begin. Sending a contract dispute letter may be a prerequisite to filing a complaint, requesting arbitration, or pursuing litigation. Failure to send this initial written notice could potentially limit your legal options later.
If initial attempts at resolution have failed, a formal demand letter signals to the solar company that you are prepared to escalate. Demand letters are often the final step before filing a lawsuit or regulatory complaint, and they give the company one last opportunity to resolve the matter voluntarily. In many jurisdictions, sending a demand letter before filing suit is either required or viewed favorably by courts.
Regardless of which type of solar cancellation letter you are sending, every letter should contain these essential elements:
Pro tip: Before sending any cancellation letter, make copies of your original contract, all correspondence, sales materials, and any notes you took during the sales presentation. Having this documentation organized will strengthen your position regardless of which template you use.
Use this template if you are within the cooling-off period (3 business days from a door-to-door sale under federal law, or longer depending on your state). This is the most straightforward cancellation — you have an unconditional right to cancel, and you do not need to provide a reason.
Time-sensitive: If you are within the cooling-off period, do not delay. Send this letter immediately via certified mail. You may also deliver a copy in person or by email to the salesperson or company, but the certified mail copy is your legal proof. More on canceling before installation →

Use this template if the cooling-off period has passed and you are disputing your solar contract based on misrepresentation, undisclosed terms, poor system performance, or other contract violations. This letter is more detailed and cites specific legal grounds for your dispute.
Note on state laws: Different states offer different levels of consumer protection. Some states, like Texas and California, have particularly strong consumer protection statutes that may provide for treble (triple) damages, attorneys’ fees, and other remedies for deceptive practices. Knowing your state’s specific protections can significantly strengthen your negotiating position. Learn more about getting out of a solar contract →
Use this template when you have already attempted to resolve the dispute informally, your previous communications have been ignored or rejected, and you are prepared to take legal action if necessary. This is a more aggressive letter that signals to the company that litigation may follow.
Critical reminder: We do not advise homeowners to stop making payments or breach contractual obligations while pursuing a dispute. Stopping payments can damage your credit score, trigger collection activity, and may weaken your legal position. Continue making scheduled payments until your attorney advises otherwise or the dispute is formally resolved. What to do when your solar company won’t let you cancel →
How you send your solar cancellation letter is almost as important as what it says. The delivery method creates the legal proof that the company received your notice.
This is the gold standard for sending legal correspondence. Certified mail provides you with a tracking number and a signed receipt (the “green card”) that proves the date the company received your letter. This is typically the delivery method that courts accept as proof of notice. The cost is approximately $7–$10 at the post office.
Before mailing your letter, make at least two copies: one for your files and one to provide to an attorney if needed later. Also keep:
In addition to certified mail, sending a copy of the letter by email can serve as a secondary notice. Email to the customer service address listed on your contract, the specific representative you worked with, and any general company email address. However, email alone is generally not sufficient — the certified mail copy is your primary proof.
If you do not receive a response by the deadline stated in your letter, send a follow-up letter by certified mail referencing your original correspondence, the deadline, and the company’s failure to respond. This creates an additional record of the company’s non-responsiveness, which can be valuable if you escalate to legal action.
Keep a written log of every communication attempt, including dates, times, names of anyone you spoke with, and a summary of what was discussed. This timeline can be critical evidence if your dispute escalates to court or regulatory proceedings.
Sending the letter is just the first step. Here is what you should do while waiting for a response:
This is critical: We do not advise homeowners to stop making payments or breach contractual obligations. Even if you believe the contract was obtained through fraud or misrepresentation, stopping payments before the dispute is formally resolved can damage your credit and potentially weaken your legal position. Continue making your scheduled payments until a qualified attorney advises you otherwise or the cancellation is confirmed in writing.
Continue documenting any issues with your solar system, including:
If you have sent a dispute or demand letter, monitor your credit report to ensure the solar company does not make negative reports in retaliation. If you see any negative reporting that you believe is inaccurate, you may have additional claims under the Fair Credit Reporting Act. What to do if a solar company threatens collections →
Consider consulting a solar panel lawyer or consumer protection attorney if:
If the company is unresponsive or uncooperative, filing complaints with the following agencies can apply additional pressure and create an official record:

Yes, you may still be able to cancel after the cooling-off period, but it is generally more complex. Post-cooling-off cancellations typically require demonstrating a legal basis such as misrepresentation, fraud, contract violations, or failure to deliver promised performance. A formal dispute letter (Template 2 above) is usually the first step, and consulting with a qualified attorney is strongly recommended before proceeding.
Always send your cancellation letter via USPS Certified Mail with Return Receipt Requested. This creates a legally verifiable record that the company received your letter and the exact date of receipt. While you may also send a copy by email for speed, the certified mail copy is the one that typically carries legal weight in court. Keep copies of everything you send.
Under the FTC Cooling-Off Rule, you have 3 business days to cancel contracts resulting from door-to-door sales. However, many states extend this period. Check your state-specific consumer protection laws, as the timeframe may be longer than the federal minimum. The cancellation must be sent (postmarked or delivered) before midnight of the last day — it does not need to be received by then.
If the solar company does not respond within the deadline you specified, send a follow-up letter referencing your original correspondence and the missed deadline. If there is still no response, consider filing complaints with your state attorney general, the FTC, and the BBB. You may also want to consult a consumer protection attorney about next steps.

For a straightforward cooling-off period cancellation within the allowed timeframe, you generally do not need a lawyer. However, for post-installation disputes, misrepresentation claims, or formal demand letters, having an attorney review your letter before sending it is strongly recommended. An attorney can ensure your letter properly cites applicable laws and preserves your legal rights for your specific situation.
No. We do not advise homeowners to stop making payments or breach contractual obligations while a dispute is pending. Stopping payments can damage your credit, trigger collection actions, and potentially weaken your legal position. Continue making your scheduled payments while you pursue cancellation or dispute resolution through proper legal channels. Consult a qualified attorney for advice specific to your situation.
