Important disclaimer: The letter templates on this page are provided for informational and educational purposes only.

Results vary by individual situation. Every contract and state law is different, and these templates may need to be modified for your specific circumstances.
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.
When You Need a Solar Cancellation Letter
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:
Cooling-Off Period Cancellation (Within 3 Days of Door-to-Door Sale)
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.
Post-Installation Disputes (Misrepresentation, Defects, Fraud)
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:
Contract Dispute Notifications
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.
Formal Demand Before Legal Action
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.
What to Include in Every Cancellation Letter
Regardless of which type of solar cancellation letter you are sending, every letter should contain these essential elements:
Essential Elements Checklist
- Your full legal name and address — exactly as it appears on the contract
- Your account or contract number — found on your contract or monthly statement
- The contract date — the date you signed the solar agreement
- The company full legal name — not just the brand name; check the contract for the exact legal entity
- Specific legal basis for cancellation — cite the applicable law, contract provision, or factual basis for your request
- Clear statement of what you want — be explicit: full cancellation, refund, system removal, lien release, etc.
- A reasonable deadline for response — typically 15 to 30 business days
- Statement preserving all legal rights — make clear that your letter does not waive any rights or claims
- Your signature and the date
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.
Template 1: Cooling-Off Period Cancellation Letter
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.

Key Points About This Template
- FTC 3-Day Rule: The federal Cooling-Off Rule gives you 3 business days (Saturdays count, Sundays and federal holidays do not) to cancel contracts from door-to-door sales. The cancellation must be sent before midnight of the third business day — it does not need to be received by then.
- State extensions: Many states provide longer cooling-off periods. For example, some states extend the period to 5 or even 7 business days for certain types of home solicitation sales. Check your state-specific door-to-door sales rights.
- No reason required: During the cooling-off period, you can cancel for any reason or no reason at all. You do not owe the company an explanation.
- Company must refund within 10 days: Under the FTC rule, the seller must return any payments within 10 business days of receiving your cancellation notice.
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 →

Re: Formal Dispute and Request for Resolution
Contract #: [Your Contract/Account Number]
Contract Date: [Date You Signed]
Property Address: [Your Property Address]
Dear Sir or Madam:
I am writing to formally dispute the solar energy agreement referenced above and to request resolution of the issues described below. I believe this contract was entered into based on material misrepresentations and/or contains terms that were not properly disclosed at the time of sale, in potential violation of [Your State]’s consumer protection laws, including [cite applicable state consumer protection statute, e.g., “the Texas Deceptive Trade Practices Act” or “California’s Consumer Legal Remedies Act”].
BACKGROUND AND FACTS:
On [date], a representative of [Solar Company Name] visited my home and presented a solar energy proposal. During this presentation, the representative made the following statements and representations:
1. [Describe specific promise #1, e.g., “That my monthly electric bill would be reduced to approximately $XX per month.”]
2. [Describe specific promise #2, e.g., “That the system would produce approximately XX kWh per year.”]
3. [Describe specific promise #3, e.g., “That there were no escalator clauses or annual price increases.”]
BASIS FOR DISPUTE:
Since installation, I have discovered the following discrepancies between what was represented and the actual terms or performance:
1. [Describe discrepancy #1, e.g., “My electric bills have averaged $XX per month, not the $XX promised.”]
2. [Describe discrepancy #2, e.g., “The system has produced only XX kWh in 12 months, XX% below promised output.”]
3. [Describe discrepancy #3, e.g., “The contract contains a 2.9% annual escalator clause in Section X that was never disclosed.”]
These misrepresentations appear to constitute [deceptive trade practices / fraud / breach of contract] under the laws of [Your State].
REQUESTED RESOLUTION:
I respectfully request the following resolution within thirty (30) calendar days of your receipt of this letter:
1. Full cancellation and rescission of the solar energy agreement and all related financing documents.
2. Removal of the solar energy system from my property at your expense, with full restoration of the roof.
3. Full refund of all payments made under the agreement, totaling approximately $[amount].
4. Release and removal of any UCC filing, lien, or encumbrance on my property.
5. Written confirmation of all of the above.
Alternatively, I am open to discussing a reasonable settlement that addresses the material harm caused by these misrepresentations.
PRESERVATION OF RIGHTS:
I am continuing to make my scheduled payments in good faith while this dispute is pending. This letter, and my continued payments, do not constitute a waiver of any rights or claims I may have under federal, state, or local law, including but not limited to claims for rescission, damages, and attorneys’ fees.
If this matter is not resolved to my satisfaction within the timeframe specified above, I intend to pursue all available legal remedies, which may include filing complaints with the [State Attorney General / Department of Consumer Affairs / FTC] and consulting with legal counsel.
I look forward to your prompt response.
Sincerely,

Key Points About This Template
- Be specific: The more specific your claims are — with dates, dollar amounts, and references to contract provisions — the stronger your letter will be. Vague complaints are easier for companies to dismiss.
- Reference state law: Cite your state’s specific consumer protection statute if you know it. If you are unsure, a consumer protection attorney can help you identify the right statutes.
- Include evidence: Attach copies (never originals) of relevant documents — your contract, utility bills showing actual vs. promised savings, screenshots of sales materials, photos of damage, and any written communications with the company.
- Keep the tone professional: Even if you are frustrated, maintain a factual, businesslike tone. Emotional language can undermine the effectiveness of your letter.
- Offer alternatives: Including a willingness to discuss settlement can encourage the company to engage rather than simply deny your claims and force litigation.
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 →

Re: FORMAL DEMAND — Contract #[Your Contract/Account Number]
Contract Date: [Date You Signed]
Property Address: [Your Property Address]
Prior Correspondence: [Dates of previous letters]
Dear Sir or Madam:
This letter serves as a formal demand for resolution of the ongoing dispute regarding the above-referenced solar energy agreement. I have previously raised these issues in correspondence dated [date(s) of prior letters], to which your company has [failed to respond / responded inadequately on (date)].
I have consulted with legal counsel regarding this matter. Based on that consultation and my own review of the facts, I believe the following claims are supported:
FACTUAL SUMMARY:
On [date], I entered into a solar energy agreement with [Solar Company Name] following a [door-to-door solicitation / online inquiry / in-home presentation]. During the sales process, your representative(s) made material representations regarding [energy savings / system performance / contract terms / financing terms] that have proven to be false or misleading, as detailed in my prior correspondence dated [date].
LEGAL BASIS:
Based on the facts of this case, I believe the following legal claims may be applicable:
1. Violation of [State]’s consumer protection / deceptive trade practices laws ([cite specific statute]).
2. Common law fraud and/or negligent misrepresentation.
3. Breach of contract, specifically Sections [X, Y, Z] of the agreement.
4. Violation of the Federal Trade Commission Act (15 U.S.C. § 45) regarding unfair or deceptive acts or practices.
5. [Any additional applicable claims, e.g., state door-to-door sales laws, Truth in Lending Act violations, etc.]
Under [cite state statute], violations of the consumer protection act may entitle me to [actual damages, treble/statutory damages, and reasonable attorneys’ fees and court costs].
DEMAND:
I hereby demand the following within fifteen (15) calendar days of your receipt of this letter:
1. Complete rescission and cancellation of the solar energy agreement and all ancillary contracts, financing agreements, and related documents.
2. Removal of the solar energy system from my property at your sole expense, including full roof restoration.
3. Full refund of all amounts paid, including but not limited to down payments, monthly payments, financing charges, and any fees, totaling approximately $[total amount].
4. Release and removal of any UCC filings, liens, or encumbrances on my property.
5. A written release of all claims related to this agreement.
CONSEQUENCES OF NON-COMPLIANCE:
If I do not receive a satisfactory response within the fifteen (15) day period specified above, I am prepared to:
1. File formal complaints with the [State Attorney General], [State Department of Consumer Protection], [Better Business Bureau], and the Federal Trade Commission.
2. Pursue legal action in [state/county] court seeking full rescission, actual and statutory damages, attorneys’ fees, and costs.
3. Pursue any other remedies available under applicable law.
I remain willing to discuss a reasonable resolution to this matter. However, the window for voluntary resolution is closing. I urge your prompt attention to this demand.
All rights and claims are expressly reserved.
Sincerely,

Key Points About This Template
- Consult an attorney first: Before sending a formal demand letter, we strongly recommend consulting with a consumer protection attorney. An attorney can verify your legal claims, strengthen the letter with proper legal citations, and prepare for potential litigation.
- Shorter deadline: This template uses a 15-day response period rather than 30, reflecting the urgency and seriousness of the demand.
- Reference prior attempts: Document your prior communication attempts to show that you have acted in good faith and given the company multiple opportunities to resolve the issue.
- CC your attorney: If you have retained an attorney, copying them on the letter signals that you are serious about legal action. Even if you have not formally retained counsel, noting that you have “consulted with legal counsel” carries weight.
- Be prepared to follow through: Do not make threats you are not prepared to act on. If you state that you will file complaints and pursue litigation, be ready to do so if the company does not respond.
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 to Send Your Cancellation Letter
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.
USPS Certified Mail with Return Receipt Requested
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.
Keep Copies of Everything
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:
- The certified mail receipt (the white receipt with tracking number)
- The return receipt (green card) when it comes back signed
- Screenshots of USPS tracking showing delivery confirmation
- Copies of all enclosures you included with the letter
Consider Sending an Email Copy
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.
Follow Up in Writing If No Response
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.
Document the Timeline
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.
What to Do After Sending Your Letter
Sending the letter is just the first step. Here is what you should do while waiting for a response:
Continue Making Payments
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.
Document Everything
Continue documenting any issues with your solar system, including:
- Monthly energy production compared to what was promised
- Your monthly payments and total amounts paid
- Any new issues that arise (roof leaks, equipment malfunctions, etc.)
- All communications with the solar company, including phone calls
- Any correspondence from the company’s financing partner
Monitor Your Credit Report
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 →
Know When to Escalate to an Attorney
Consider consulting a solar panel lawyer or consumer protection attorney if:
- The company ignores your letter entirely
- The company responds but refuses to address your concerns
- The company makes legal threats or counter-claims
- You need help calculating damages or understanding your legal options
- The amount in dispute is significant (generally over $5,000)
- You are considering filing a lawsuit or joining a class action lawsuit
File Regulatory Complaints
If the company is unresponsive or uncooperative, filing complaints with the following agencies can apply additional pressure and create an official record:
- Your state Attorney General’s office — most states have a consumer complaint portal
- The Federal Trade Commission (FTC) — file at ReportFraud.ftc.gov
- The Better Business Bureau (BBB) — companies often respond to BBB complaints
- Your state’s Public Utilities Commission — if applicable in your state
- The Consumer Financial Protection Bureau (CFPB) — if the dispute involves financing
