Solar Contract Demand Letter Sample: Free Template and Drafting Guide

The escalation letter that comes after cancellation has already failed. Copy-paste sample with fillable fields, a section-by-section explanation of what each paragraph is doing, and the 30-day deadline convention that is a statutory prerequisite in some states.

Published May 9, 2026 · Educational template, not legal advice · Our methodology

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.

Which document do you need?Two different letters, two different stages

  • 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

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.

[Your full legal name] [Your street address] [City, State ZIP] [Phone] | [Email] [Date] VIA USPS CERTIFIED MAIL, RETURN RECEIPT REQUESTED AND VIA EMAIL TO [legal or general counsel email] [Installer's exact legal entity name, e.g. "ABC Solar Holdings, LLC"] Attn: Legal Department / General Counsel [Registered agent address or corporate headquarters] RE: Demand for [rescission / refund / cure] — Contract No. [number], dated [contract date] Property: [installation address] To Whom It May Concern: I am the homeowner and counterparty to the above-referenced solar [purchase and installation / lease / power purchase] agreement with [Company]. I write to demand [state the remedy in one clause] and to give [Company] an opportunity to resolve this matter before I pursue the remedies available to me. 1. Factual background On [date], [Company]'s sales representative, [name or description], represented to me that [the specific representation — e.g. "the system would produce at least 11,400 kWh annually and my monthly electricity cost would fall to approximately $30"]. I relied on that representation in signing the agreement on [date]. [Company] installed the system on [date]. Since [date], actual results have been materially different: [specific facts with numbers and dates — e.g. "the system produced 7,120 kWh over the 12 months ending [date], against the 11,400 kWh represented, and my combined utility and financing cost is $214/month, exceeding my pre-installation utility cost of $168/month"]. I notified [Company] of this issue on [dates] by [phone / email / support ticket numbers]. [Company]'s response to date has been [describe factually]. The matter remains unresolved. 2. Contract provisions at issue The conduct described above appears inconsistent with the following provisions of the agreement: [Section __, quote the language] and [Section __, quote the language]. It also appears inconsistent with [State]'s consumer-protection statute, which generally prohibits unfair or deceptive acts and practices in consumer transactions. 3. Damages The loss I have sustained to date is [$ total], itemized as follows: [Line item — e.g. payments made to date] .......... [$ amount] [Line item — e.g. excess utility cost vs. represented] .......... [$ amount] [Line item — e.g. out-of-pocket repair or inspection cost] .......... [$ amount] TOTAL .......... [$ amount] 4. Demand I demand that [Company], within thirty (30) days of the date of this letter: [state the remedy precisely — e.g. "(a) rescind the agreement and the associated financing; (b) remove the system and restore the roof to its pre-installation condition at Company's expense; and (c) refund $______"]. 5. Response deadline and reservation of rights Please direct your written response to me at the address above on or before [calendar date = letter date + 30 days]. If I have not received a written response by that date, I intend to pursue the remedies available to me, which may include filing complaints with the [State] Attorney General and the Consumer Financial Protection Bureau, initiating arbitration if required by the agreement, or filing suit. Nothing in this letter waives any right or remedy available to me, all of which are expressly reserved. I remain current on my payment obligations under the agreement and will continue to be while this dispute is pending. Enclosures: [list — contract, monitoring data, correspondence, photos] Sincerely, [Signature] [Printed name]

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.

1. Factual background Section [__] of the agreement guarantees annual production of [__] kWh and provides for compensation of [$__] per kWh of shortfall. For the guarantee year ending [date], the system produced [__] kWh according to [Company]'s own monitoring platform ([Enphase Enlighten / SolarEdge / Tesla App]), a shortfall of [__] kWh. I submitted a claim on [date]. [Company] [has not responded / paid $____, which does not match the contract formula]. 2. Contract provisions at issue Section [__] obligates [Company] to compensate the shortfall at the contracted rate. [If applicable: "Company's calculation applies a weather adjustment / system-availability carve-out that does not appear in the executed agreement."] 3. Damages Applying the contract formula: [__] kWh shortfall × [$__] per kWh = [$__] owed. Amount paid to date: [$__]. Balance owed: [$__].

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.

1. Factual background [Company] installed the system on [date]. As of the date of this letter — [__] days later — [the system has never been energized / permission to operate has never been obtained from [utility] / the permit was never finalized with [jurisdiction] / the installation caused [describe damage]]. I have contacted [Company] on [dates] regarding this. [Describe the responses factually.] Meanwhile, financing payments of [$__] per month began on [date] for a system that has produced [__] kWh. 2. Contract provisions at issue Section [__] obligates [Company] to [quote the completion / permitting / workmanship language]. [Company] has not performed. 3. Damages Financing payments for a non-operational system .......... [$__] [Repair / remediation cost, supported by estimate] .......... [$__] [Utility cost that the system was to offset] .......... [$__] TOTAL .......... [$__]

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.

SectionQuestion it answersWhy it changes the outcome
Recipient blockWho is legally responsible?Naming the signing entity and the legal department routes the file to risk assessment rather than to a retention script.
1. ChronologyWhat 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. ProvisionsWhat obligation was broken?Quoting section numbers proves the contract was read. It also narrows the dispute to language the company itself drafted.
3. DamagesWhat is this worth?An itemized number can be evaluated against litigation cost. A vague grievance cannot be priced, so it gets filed.
4. DemandWhat do you want?A specific remedy is something the reviewer can approve. "Make this right" is not.
5. Deadline + reservationWhat 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

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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).
  6. 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 — and the two things a 20-minute review usually catches. Free, no obligation.

What Happens After You Send It

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.

Frequently Asked Questions

Is a demand letter legally required before suing a solar company?
Usually not, but there are real exceptions. Massachusetts requires a written 30-day demand before most consumer claims under Chapter 93A, and skipping it can forfeit multiple damages and fees or get the case dismissed as premature. Some contracts also impose their own notice-and-cure procedure. Check both your state's law and your agreement.
What if they don't respond at all?
Silence is the most common outcome and is still useful. The letter plus the certified-mail receipt documents that you gave notice and a chance to cure. Typical next steps: a state AG complaint, a CFPB complaint on the loan, BBB arbitration, contractual arbitration, or suit — often several in parallel.
Can a demand letter be used against me later?
Yes. Federal Rule of Evidence 408 limits using compromise offers to prove liability, but it does not apply before a claim is genuinely disputed, has express exceptions, and does not prevent the letter from being discoverable. Assume anything you write will be read back to you — which is why accuracy matters more than force.
Should I include a confidentiality demand?
Generally no, not in the opening letter. Confidentiality is something the company will typically ask for as a term of settlement, and offering it up front gives away a bargaining chip for nothing. If you have already posted publicly about the dispute, mention that to any attorney you consult — it can affect strategy.
Does email count as delivery?
Email proves receipt poorly and satisfies no formal service requirement. Send by USPS Certified Mail with Return Receipt Requested — that generates the delivery record — and email the same document the same day for speed. Where your contract specifies a notice method or address, follow it exactly in addition.
How much should I demand?
A figure you can support line by line from documents you already have. Inflated demands invite dismissal as unserious and can undercut your credibility on the items that are well-supported. Whether your state's statute allows multiple damages or fee-shifting on top is a question for an attorney, not a number to assume.

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.
