Door-to-door solar sales: your rights at your own door
A federal rule from 1974 governs what happens when a solar contract is signed at your kitchen table. Most people are told about it wrongly, if at all.

The short answer
The rule applies even when you asked them to come
The definition of a door-to-door sale is the single most misunderstood sentence in the rule, and getting it wrong costs people their cancellation window.
The Cooling-Off Rule defines a door-to-door sale as one "in which the seller or his representative personally solicits the sale, including those in response to or following an invitation by the buyer, and the buyer's agreement or offer to purchase is made at a place other than the place of business of the seller".
Read the two halves. The first says an invitation from you does not take the sale outside the rule. You can fill in a form on a website, request a quote, book the appointment yourself and choose the time, and the rule still applies. The second says what actually matters is where you signed, not where you were pitched and not where the panels end up.
The definition then gives its own examples of places that are not the seller's place of business: "sales at the buyer's residence or at facilities rented on a temporary or short-term basis, such as hotel or motel rooms, convention centers, fairgrounds and restaurants, or sales at the buyer's workplace or in dormitory lounges".
So a signature at your kitchen table is covered. So is one at a home show booth, a hotel conference room, a county fair table, or your desk at work. What is not covered is a sale made after you visited a permanent showroom where the goods are on display on a continuing basis, which is rare in residential solar.
The four tests, applied to a solar contract
Consumer goods or services? Yes. The rule covers things bought "primarily for personal, family, or household purposes", and a rooftop system on an owner-occupied home qualifies.
Personally solicited? Yes. An in-home closer is personal solicitation, and an invitation from you does not change that.
Signed away from the seller's place of business? Yes, if you signed at home. That is the definition's own first example.
Purchase price at or above the threshold? Yes, by orders of magnitude. The threshold at your residence is $25, and "purchase price" is defined to include all interest and service charges.
Neither of the rule's two standalone exemptions, for motor vehicles at temporary locations and for arts and crafts at fairs, touches solar.
What the rule actually requires of the seller
| Requirement | What the rule says | Citation |
|---|---|---|
| Tell you out loud | The seller must "inform each buyer orally, at the time the buyer signs the contract" of the right to cancel. Failing to is a violation on its own. | 429.1(e) |
| Put it by your signature | A statement in minimum 10-point bold face, in immediate proximity to the signature line, saying you may cancel before midnight of the third business day. | 429.1(a) |
| Hand you two copies of the notice | A completed "Notice of Cancellation" in duplicate, 10-point bold face, captioned either NOTICE OF RIGHT TO CANCEL or NOTICE OF CANCELLATION. | 429.1(b) |
| Fill in the dates before handing it over | The seller must complete the seller’s name, address, the transaction date and the deadline date, and the deadline may be no earlier than the third business day. | 429.1(c) |
| Use your language | The contract and the notice must be in the same language as the oral sales presentation. The rule’s own worked example is Spanish. | 429.1(a), (b) |
| Refund within ten business days | After a valid cancellation, payments, trade-ins and any negotiable instrument come back within ten business days, and any security interest is cancelled. | 429.1(g) |
| Not sell your loan straight away | The seller may not negotiate, transfer, sell or assign the note to a finance company or third party before midnight of the fifth business day. | 429.1(h) |
| Not ask you to waive any of it | Confessions of judgment and waivers of the cancellation right may not appear in the contract or receipt at all. | 429.1(d) |
| Not misdescribe the right | Misrepresenting the buyer’s right to cancel is a separate violation. | 429.1(f) |

Notice how many of these are duties the seller owes before you have decided anything. A contract handed over with the cancellation dates left blank has already failed the rule.
Saturday counts, and that makes the window shorter than you think
The rule defines a business day as "any calendar day except Sunday or any federal holiday". Saturday is a business day for these purposes. Most people assume the opposite, and the assumption costs a day.
Work an example. You sign on a Thursday evening. Friday is business day one. Saturday is business day two. Sunday does not count. Monday is business day three, so your right expires at midnight on Monday. If you had assumed Saturday and Sunday were both excluded, you would have believed you had until Wednesday, and you would have been two days wrong.
This is exactly why the rule requires the seller to write the actual deadline date on the notice rather than leaving you to count. If your notice has a blank where the date should be, you are missing something the seller was required to give you.
State law can count differently. Some states exclude Saturday as well, which makes their window longer in real time even when the number of days is the same. We cover the state-level variation separately.
A contract signed Thursday evening
-
Thursday
The transaction dateYou sign. The seller must tell you about the cancellation right out loud, and hand you two copies of a notice with Monday already written in as the deadline.
-
Friday
Business day oneThe clock is running. Nothing you need to do yet, but this is the day to read the contract properly rather than the proposal.
-
Saturday
Business day twoSaturday counts under the federal rule. This surprises most people and is the most common reason a window is miscounted.
-
Sunday
Not a business dayExcluded by 429.0(f), along with federal holidays.
-
Monday, midnight
Business day three: the deadlineNotice must be sent by midnight. The rule accepts the signed cancellation form "or any other written notice", so the form is not the only route.
-
Within 5 business days
Your loan may not be sold yetThe seller may not assign the note to a finance company before midnight of the fifth business day, which keeps the paper in reach for a short while after your window shuts.
-
Within 10 business days
Money comes backOn a valid cancellation, payments and any negotiable instrument are returned and any security interest is cancelled.
-
Within 20 days
Uncollected equipmentIf you made goods available and the seller has not picked them up within 20 days of your notice date, you may keep or dispose of them without further obligation.
The financing detail that changes which law applies
The financing carve-out is the part almost nobody explains, and it is the part that occasionally rescues someone who is already past day three.
The Cooling-Off Rule contains a carve-out at 429.0(a)(2): it does not apply to a transaction "in which the consumer is accorded the right of rescission by the provisions of the Consumer Credit Protection Act". That is a reference to the Truth in Lending Act. The two regimes are mutually exclusive by design, so exactly one of them governs your contract.
Which one depends on what secures your loan. TILA rescission attaches only where a security interest "is or will be retained or acquired in any property which is used as the principal dwelling" of the borrower. In practice that means a solar loan secured by a mortgage or deed of trust on the house, a home-equity product, or a PACE assessment recorded as a lien on the property. A solar loan that is unsecured, or secured only against the equipment, does not create an interest in your home and so does not trigger TILA. The FTC rule governs instead.
Both regimes happen to give three business days, so this can look like a distinction without a difference. It is not, because they start the clock differently.
The FTC clock runs from the date of the transaction. The TILA clock runs from the latest of consummation, delivery of the rescission notice, or delivery of all material disclosures. And if the notice or the material disclosures were never properly delivered, the right to rescind does not expire in three days. It expires three years after consummation, or on sale or transfer of the property, whichever comes first.
There is one more consequence worth knowing if work has been scheduled fast. Under Regulation Z, during a TILA rescission period "no money shall be disbursed other than in escrow, no services shall be performed and no materials delivered until the rescission period has expired". A crew arriving the next morning on a home-secured loan is not a sign of good service.
And your state may fill the gap the federal rule leaves. Kentucky is the clearest case we found. Its statute gives a buyer ten business days to rescind a home solicitation sale "on loans in which a security interest is taken in the principal dwelling of the buyer", running from the later of loan consummation or delivery of the material disclosures required under the Truth in Lending Act. That is precisely the fact pattern the federal rule pushes out to TILA, and Kentucky more than triples the period there.
So do not conclude that financing shortened your window without checking your own state. In at least one state, a loan secured by the house makes the window longer rather than shorter, and North Dakota separately gives buyers aged sixty-five or over fifteen business days on an ordinary solicitation sale. We cover what we verified state by state on a separate page.
We are not telling you which regime covers your contract, because that depends on documents we have not seen. We are telling you the question to ask: is this loan secured by my house? The answer decides which law you are under, and in one branch it decides whether your deadline was three days ago or three years from now.
Two three-day rights that are not the same right
| FTC Cooling-Off Rule | TILA right of rescission | |
|---|---|---|
| When it applies | Signed away from the seller’s place of business, and TILA rescission does not apply | A security interest is taken in your principal dwelling |
| Typical solar case | Unsecured loan, cash purchase, or a loan secured only against the equipment | Mortgage or deed of trust on the home, home-equity product, or a PACE assessment |
| Length | Three business days | Three business days |
| Clock starts | The date of the transaction | The latest of consummation, delivery of the notice, or delivery of all material disclosures |
| If the paperwork was never properly given | Still three business days | Three years from consummation, or until sale or transfer of the property |
| Work during the window | Not addressed by the rule | No services performed and no materials delivered until it expires |
| Money back | Within ten business days | Within twenty calendar days, and the security interest becomes void |

One further live change: the CFPB’s residential PACE rule, issued 17 December 2024, applies TILA civil liability to PACE transactions and took effect on 1 March 2026.
How to cancel so that it holds
- 1 Work out your real deadline today
Count business days from the transaction date, excluding Sundays and federal holidays but including Saturday. If the seller filled in the notice, use their date, since it may not be earlier than the third business day. If they left it blank, that is a separate problem worth writing down.
- 2 Write it, do not phone it
The rule accepts "a signed and dated copy of this Cancellation Notice or any other written notice". You do not need their form. You do need something written, dated and sent before midnight on the deadline.
- 3 Keep proof of when you sent it
The federal rule is about sending by the deadline rather than about them receiving it by then. Some state statutes make cancellation effective on deposit in the mail, and at least one requires certified mail with return receipt. Send it in a way you can evidence, and keep the receipt.
- 4 Send it to the address on the notice
That address is one of the things the seller was required to fill in. If the contract has no cancellation address, some state statutes let you cancel by any reasonable method, which is a gap that works in your favour rather than against you.
- 5 Say nothing more than that you are cancelling
You do not owe anyone a reason. "I am cancelling this transaction", the date, the contract number and your signature is a complete cancellation. Reasons invite negotiation, and negotiation consumes days you do not have.
- 6 Make equipment available, do not ship it back unasked
If anything was delivered, make it available at your residence in substantially the condition you received it. If the seller does not collect within 20 days of your notice date, you may keep or dispose of it without further obligation.
- 7 Escalate if the refund does not arrive
The refund window is ten business days. If it passes, you have a documented rule violation as well as a debt, which is a materially stronger position than a billing complaint. Your state consumer protection office and the FTC both take reports.
You cannot be asked to sign the right away
Waivers of the cancellation right and confessions of judgment may not appear in a door-to-door contract or receipt at all. That is 429.1(d), and it is a flat prohibition rather than a condition.
The rule does contain a narrow emergency exception, and it is worth knowing precisely because it is the shape a bad waiver imitates. To fall outside the rule on emergency grounds, you must have initiated the contact, the goods or services must be needed for "a bona fide immediate personal emergency", and you must furnish a separate dated and signed statement in your own handwriting describing the situation and expressly waiving the right.
Two things follow. A knock on your door can never qualify, because you did not initiate the contact. And a pre-printed waiver clause in a contract does not satisfy any part of it. If someone presents solar as an emergency requiring you to sign away a cancellation right today, every element of that is outside the rule.
What the FTC has actually alleged about solar door-to-door selling
We searched the FTC's case library rather than relying on secondary summaries, and the picture is narrower and more specific than the general reputation of the industry suggests.
The first finding is a negative one, and it is genuinely useful. We found no FTC enforcement action against a solar seller under the Cooling-Off Rule itself. The rule is the source of your rights, but it is not where the federal cases have been brought. The actions that exist were brought under the Telemarketing Sales Rule, FTC Act section 5, and a mortgage advertising rule.
In July 2023 the FTC and the State of Arizona filed a complaint in the District of Arizona against Vision Solar LLC, Solar Xchange LLC and an individual. As alleged in that complaint, Vision Solar paid telemarketers to book in-home sales appointments; those telemarketers placed calls to numbers on the National Do Not Call Registry; agents falsely claimed affiliation with an electric utility or a government entity; and savings claims of 20% to 50% off current bills were made without substantiation. Solar Xchange and the individual defendant settled by stipulated order with a suspended civil penalty judgment and conduct bans. Vision Solar LLC did not settle, and the case page records the matter as pending. Everything in this paragraph is an allegation in a complaint, and nothing here should be read as a finding against any defendant.
A 2022 action concerned PACE financing rather than the panels. The complaint alleged that a financier trained and authorised home-improvement contractors, explicitly including solar-panel installers, to sell PACE financing door-to-door, and that contractors told homeowners the resulting first-priority property-tax lien would not interfere with selling or refinancing the home. That matter settled with $3 million dedicated to consumer relief, of which the FTC reported distributing more than $2.9 million to 960 consumers in July 2025. The settlement did not remove the liens.
An earlier action, filed 2016 and settled 2017, concerned a solar lead-generation robocall operation rather than a seller: prerecorded calls telling consumers to press one to lower their electric bill, after which the consumer was transferred and their details sold to an installer as a lead.
Read together, these describe a pattern about how the appointment gets made rather than about what happens once someone is in your living room. The lead generator, the telemarketer and the closer are frequently three different businesses, which is a structural point we cover separately.
What to do while someone is standing at your door
Nothing has to be decided today
A solar system is a twenty-five-year asset attached to your roof. There is no version of this where the correct amount of time to consider it is the length of one visit. An offer that expires when the visitor leaves is telling you something about the offer.
You are also allowed to simply not answer the door, and in some states a posted no-soliciting sign now carries legal weight against solar canvassers specifically.
Ask who each person actually works for
Ask whether the person at your door is an employee of the company whose name is on their shirt, whether that company will perform the installation, and if not, which licensed company will. In some states the salesperson holds a registration of their own that you can check independently, tied to a specific contractor.
Write the answers down while they are being given. They are checkable afterwards, and they are the answers that turn out to matter if something goes wrong.
Take the paperwork, not the pen
Ask for the full proposal, the contract, the manufacturer warranty documents and the financing terms, and say you will read them. A company confident in its numbers will leave them with you. This costs you nothing and it converts a sales visit into a set of documents you can check against the utility’s own rates, the manufacturer’s published warranty, and the state licence register.
If you did sign, act on the calendar rather than the feeling
Regret is not the trigger. The deadline is. Count the days properly, including Saturday, and if you are inside the window, send written notice today rather than sleeping on it. You can always sign a better contract next month; you cannot recover a window that closed.
Method and limitations
How the rule text was obtained
16 CFR §§ 429.0, 429.1, 429.2 and 429.3 were read in full at the Cornell Legal Information Institute, because the government's own eCFR site blocks automated retrieval. Statutory text for the TILA provisions was read from the same source. Every quotation is verbatim and carries its section number so it can be checked independently.
The enforcement picture comes from the FTC's own case library and press releases, searched directly rather than taken from secondary reporting.
What is not settled, and is not claimed here
Whether a purely remote solar sale is covered is genuinely open. The rule excludes transactions "conducted and consummated entirely by mail or telephone" with no other contact before performance. That language predates video calls and electronic signature, and we found no FTC interpretation addressing whether a video-call close falls inside it. This page does not tell you a remote sale is covered or uncovered, because nobody can honestly tell you that from the sources available.
We do not state what share of solar loans are secured by the home. We could not source it, so the page describes both branches and tells you how to find out which one you are in.
This is a floor, not the whole picture
The rule expressly does not preempt stronger state or local law. It displaces only state law that is "directly inconsistent", and defines that to include any state rule giving a weaker cancellation right than the federal one. So three business days is a minimum. Your state may give you more, may count the days differently, and may impose obligations on the seller that the federal rule does not.
This page is the federal layer. The state layer is a separate page, because it varies enough that combining them would produce something accurate about nowhere in particular.
Not legal advice
This is a description of published rules, not advice about your contract. Cancellation rights turn on facts we have not seen, including where you signed, what secures your loan and what your state provides. If a significant sum is involved and the deadline is close, an hour with a consumer attorney or a call to your state consumer protection office is worth more than any web page.

Primary-source research, data analysis and fact checking
We are a research desk, not a sales floor. We read the statute, the tariff, the code section, the federal filing or the manufacturer data sheet ourselves, and we publish the figure with the document it came from and the date we retrieved it. Where a number cannot be traced to a primary source, we publish the shorter page and say what we could not verify. That rule has cost us whole sections, and it is the reason the rest can be trusted.

How this desk works
- Primary sources only. Statutes from the legislature’s own publishing system, federal data from the agency that collects it, code text from the adopted edition, manufacturer claims from the data sheet. We do not cite an article that cites a source; we go and read the source.
- Every figure carries its provenance. A named document and the date we retrieved it, so you can check it and so you know how old it is. Retrieval dates are not decoration: an EIA rate from May is a different fact from an EIA rate from August.
- We publish what we could not verify. Every research page carries a section naming the things we tried to establish and could not, and why. A paywalled standard, a state website that refused the request, a manufacturer that publishes no figure at all.
- We separate measurement from modelling from our own reasoning, and label which is which on the page. A laboratory measurement, an assumption inside a modelling tool and our own inference are three different kinds of claim and they are never presented as one.
- We do not sell solar, and we take no payment for placement, ranking or a favourable mention. Nobody buys a position on this site.
Data as of regulation text, statutes and FTC case records read on 2 September 2026. Authorship on this site is organisational: the analysis belongs to the desk rather than to a named individual, and we do not publish credentials we do not hold. Our editorial policy sets out how we source, date and correct what we publish.
