A demand letter is the pre-litigation escalation that follows a failed cancellation: different document, different recipient, different legal posture. Where a cancellation letter notifies the installer that you are rescinding under the cooling-off rule, a demand letter notifies the installer's legal department of specific damages you are claiming and a deadline by which they must cure or pay before you pursue other remedies.
Cancellation letter
Day 1–3 · Rescission window
- Goal: unwind the contract before it takes effect
- Recipient: sales or contracts address on the agreement
- Basis: your cooling-off right, no wrongdoing needed
- Asks for: cancellation and deposit return
- Tone: notice, not argument. One page.
- → Use the rescission letter template instead (Day 1–3, different document)
Demand letter (this page)
Day 30+ · Pre-litigation
- Goal: get paid or get the contract undone after the fact
- Recipient: legal department or registered agent
- Basis: breach, misrepresentation, or statutory violation
- Asks for: a specific dollar figure or remedy, by a date
- Tone: factual, itemized, deadline-bearing
- → You are in the right place if cancellation already failed

Demand Letter vs Cancellation Letter. Which Do You Need?
A solar demand letter is a pre-litigation notice sent to an installer's legal department that states the facts of a dispute, the contract provisions breached, a quantified damages figure, a specific remedy, and a deadline to respond. A cancellation letter does none of those things. It simply exercises a rescission right inside a short window and needs no allegation of wrongdoing at all.
The distinction matters because the two documents fail in opposite directions when swapped. A cancellation letter sent on Day 90 gets a form reply saying your window closed. A demand letter sent on Day 2 wastes the strongest, cheapest right you have, the unconditional cooling-off cancellation, by converting a clean statutory exit into an argument about fault.
If you are still inside the rescission window, stop reading and go to the rescission letter template (Day 1–3, different document). If that window has closed, or you sent the cancellation letter and the company refused or ignored it, this page is the next escalation.
Read this before you copy anything below. A demand letter is not a neutral document. It can constitute formal notice, start or satisfy clocks, waive or preserve rights depending on its wording, and be read back to you later. The sample below is general information to help you understand the format, not legal advice and not a document we are preparing for you.
Getting the damages figure or the legal basis wrong can cost you more than sending nothing. In our assessment, having an attorney review or sign the letter is the single highest-leverage decision at this stage. See have an attorney sign the demand.
Free Sample Demand Letter (Copy-Paste, Fillable)
Bracketed fields in teal are fill-ins. Everything else is scaffolding you can keep, cut, or rewrite. This version is drafted for the most common solar fact pattern: a sales representative made specific representations about production or savings, you relied on them, and the delivered system is materially different.
Drafting note: Keep the whole letter under two pages. Legal departments triage by facts, dates, and dollar figures, every adjective you add gives a reviewer something to argue with instead of something to price.

Two Variants: Swap These Sections In
The letterhead, opening, deadline, and reservation-of-rights language stay identical across fact patterns. Only Sections 1 through 3 change. Rather than reprint the whole letter twice, here are the two most common substitutions.
Variant A. Production-shortfall demand
Use when the contract contains an actual production guarantee and the installer is refusing to pay, or paying an amount you believe is calculated wrongly. This is a contract-math dispute, not a misrepresentation dispute, and it is usually the stronger of the two because the number is in the agreement.
If you are not sure whether the installer's math is right, run it first. See our demand-letter template for shortfall non-payment for the calculation and the common discounts installers apply.
Variant B. Failed-install / breach demand
Use when the physical work is the problem: the system was never completed, never energized, never permitted, or the installation damaged your property.
What Each Section Is Actually Doing
The structure is not decorative. Each block exists to answer a question the recipient's file reviewer is required to answer before they can price your claim.
| Section | Question it answers | Why it changes the outcome |
|---|---|---|
| Recipient block | Who is legally responsible? | Naming the signing entity and the legal department routes the file to risk assessment rather than to a retention script. |
| 1. Chronology | What happened, and when? | Dates fix the timeline. A reviewer who can reconstruct events without calling you is a reviewer who can settle without escalating. |
| 2. Provisions | What obligation was broken? | Quoting section numbers proves the contract was read. It also narrows the dispute to language the company itself drafted. |
| 3. Damages | What is this worth? | An itemized number can be evaluated against litigation cost. A vague grievance cannot be priced, so it gets filed. |
| 4. Demand | What do you want? | A specific remedy is something the reviewer can approve. "Make this right" is not. |
| 5. Deadline + reservation | What happens if we ignore this? | A calendar date creates an internal due date. The reservation language keeps you from accidentally waiving claims you have not identified yet. |
Two things to keep out of the letter. Do not threaten criminal prosecution, referral to law enforcement, or anything of the kind to gain leverage in what is a civil money dispute, depending on the jurisdiction that can be improper, and it hands the company a story that is no longer about your contract. And do not cite statutes, cases, or damages multipliers you have not verified apply to your state and your facts. An invented citation discredits every accurate paragraph around it.
How to Write a Solar Demand Letter: 6-Step Process
- Identify the legal-department recipient. Send it to the entity that signed your contract, not the sales office. Look up the registered agent through your Secretary of State's business search and address it to Legal Department / General Counsel. Sales routes complaints to retention; legal routes them to risk.
- State the factual chronology. Events in date order: the pitch, what was represented, the signing, the install, when the problem appeared, every contact attempt since. Dates and numbers, not adjectives.
- Cite the breached provisions. Quote the sections by number and language. Where a state consumer-protection statute is relevant, reference it generally rather than overclaiming a specific remedy you have not confirmed.
- Quantify damages. Itemize line by line with a total. Overpayments, repair costs, the gap between represented and actual production, out-of-pocket costs. Then state the remedy plainly.
- Set a hard deadline, typically 30 days. Give a calendar date, not a duration. Thirty days is customary, defensible as reasonable, and in some states a statutory prerequisite (see below).
- Send certified mail, plus email. USPS Certified Mail with Return Receipt Requested, emailed copy the same day. Keep the receipt, the tracking record, and a PDF of the signed letter. Proof of delivery is what turns a complaint into documented notice.
Why 30 days, specifically: in Massachusetts, a written 30-day demand letter is a statutory prerequisite to most consumer claims under G.L. c. 93A, and skipping it can cost you multiple damages and attorney's fees or get a premature suit dismissed. Most states have no such requirement, but the 30-day convention is near-universal because no court finds it unreasonable. Confirm your own state's rule before you rely on the timing.
Have an attorney review your demand letter before you send it
The damages figure and the legal basis are the two things that are expensive to get wrong. A licensed attorney can check both. If you want help with the contract itself, we can connect you with solar contract exit companies that may be able to help.

Based on the fact patterns we see in homeowner intake, four outcomes account for nearly everything. None of them are guaranteed, and which one you get depends more on the strength of your documentation than on the letter's tone.
Silence (the most common outcome)
Many installers, particularly those with high complaint volume, do not respond to homeowner-signed letters at all. This is not a failure. The unanswered letter plus a certified-mail receipt is documentary proof that you gave notice and an opportunity to cure: which is exactly what a regulator, an arbitrator, or a judge will ask whether you did.
A retention or "goodwill" call
Sometimes the letter is routed back down to customer service, who calls to offer a service visit or a small credit. Get any offer in writing before you engage with it, and be careful: accepting a payment framed as full settlement can close claims worth considerably more.
A counter-offer from counsel
The best realistic outcome. If the company's legal department responds with a number, your itemized damages figure just became the ceiling of a negotiation rather than the opening of one. This is the point at which representation typically pays for itself.
A denial letter
A substantive denial is more useful than silence. It commits the company to a position and a set of facts before anyone is under oath. Denials frequently contain admissions the company would not make later.
When to Send a Demand Letter vs File Suit
A demand letter is generally not a legal prerequisite to filing suit, with state-specific exceptions like the Massachusetts rule above. The reason to send one anyway is economic: litigation is slow and expensive for both sides, and a letter that credibly prices the dispute gives the company a cheaper option.
Send the letter first when your damages are documented, your contract language is on your side, and you would genuinely accept the remedy you are demanding. Skip straight to counsel when a limitations period may be running (these vary meaningfully by state and by claim type: do not assume you have four years), when your contract has a mandatory arbitration clause with its own notice procedure, or when the company has already sued you or sent the account to collections.
Related escalation paths, which can run in parallel with the letter rather than after it: a state attorney general complaint (parallel filing), a CFPB filing on the loan side, BBB arbitration if the demand is ignored, or the choice between arbitration and litigation if the demand fails.

When to Have an Attorney Send the Letter Instead
A letter from a homeowner says "I am upset." A letter on law-firm letterhead says "someone who bills by the hour has evaluated this claim and concluded it is worth their time." Those are different messages, and companies price them differently.
In our assessment, attorney involvement is worth pursuing when the dollar amount exceeds a few thousand, when the contract has an arbitration clause, when your state's consumer-protection statute may provide fee-shifting or multiple damages (New Jersey's Consumer Fraud Act and Massachusetts's Chapter 93A are the most-cited examples, and both have specific proof requirements), or when the facts involve misrepresentation rather than simple non-performance.
The fee-shifting point is the one homeowners most often miss. Where a statute allows a prevailing consumer to recover attorney's fees, the economics change, many consumer-protection attorneys will take the matter on contingency or a flat fee precisely because the fee award is available. An attorney review of your specific contract is the only way to know which of these applies to you. See our guide to finding a consumer-protection attorney.
Not sure your damages number holds up?
The itemized figure is what the other side prices. Have a licensed attorney check your contract and your math before the letter goes out. If you want help with the contract itself, we can connect you with solar contract exit companies that may be able to help.

Is a demand letter legally required before suing a solar company?
What if they don't respond at all?
Can a demand letter be used against me later?
Should I include a confidentiality demand?
Does email count as delivery?
How much should I demand?
What if the solar company ignores the demand letter?
Silence is common and is itself useful. The unanswered letter plus a certified-mail receipt documents that you gave notice and an opportunity to cure. Typical next steps include a state attorney general complaint, a CFPB complaint on the loan side, BBB arbitration, contractual arbitration, or suit.
How long should I give the company to respond?
Thirty days is the customary window and is long enough that a court will not view it as unreasonable. In Massachusetts, a 30-day demand letter is a statutory prerequisite to most consumer claims under Chapter 93A. Always give a specific calendar date rather than a duration.
Do I need an attorney to send a demand letter?
You can generally send one yourself, but a letter on law-firm letterhead typically carries substantially more weight because it signals that counsel has evaluated the claim and litigation costs are now real. Many consumer-protection attorneys review or send demand letters on contingency or for a flat fee.
How is a demand letter different from a cancellation letter?
A cancellation letter notifies the company you are rescinding inside the cooling-off window, usually within three business days, and goes to the sales or contracts address. A demand letter comes later, claims money damages for conduct that already occurred, sets a response deadline, and is addressed to the legal department.
What is a solar demand letter?
A solar demand letter is a pre-litigation notice sent to an installer's legal department stating the facts of a dispute, the contract provisions breached, a quantified damages figure, a specific remedy, and a deadline to respond. It is the escalation step after cancellation attempts have failed, typically sent 30 or more days into a dispute.
Keep paying while the demand is pending. We are not telling you to stop paying. The strategies in this guide work with payments current; they collapse if you go delinquent. SolarPanelExit.com does not advise homeowners to stop making payments or breach contractual obligations, a demand letter does not suspend the contract, and missed payments hand the company a counter-defense while damaging your credit.
