Door-to-Door Solar Salesman at Your Door? What to Do and Say

When a solar salesperson knocks, the safest move is simple: take a card, don’t share your bill or account number, don’t sign anything, and say you’ll compare quotes on your own time. Door-to-door sales are not illegal, and some reps work for honest companies. But the format is built to get a signature before you can check the numbers, which is exactly when expensive mistakes happen. If you’ve already signed, federal law usually gives you three business days to cancel.

Why door-to-door solar sales are risky

Many large solar companies sell through independent “dealers” or sales organizations that are paid by commission and don’t install anything themselves. The salesperson at your door may never see your project again after you sign. That arrangement rewards speed and bigger contracts, not a good fit for your home. See sales-only subcontractors.

Doorstep sales also strip away the things that protect you: time, comparison quotes and a calm read of the contract. Of the tactics listed in our red flags library, a large share happen most often in person: utility impersonation, show me your bill, tablet signing rush, today-only pricing and cooling-off waiver pressure.

What they usually say at the door

You’ll often hear one of these openers. None of them is a reason to keep talking.

What you hear	What it usually means
“I’m with the utility” or “I’m here about your meter”	They aren’t. Utilities rarely send unannounced reps to sell anything. See utility impersonation
“There’s a new state program” or “free government solar”	A lease, PPA or loan with 20 to 25 years of payments. See free solar claims
“Your neighbors are all going solar”	Social pressure. Ask for the neighbor’s address and you’ll rarely get it
“We’re only doing a few houses in this area”	Fake scarcity
“Can I see your bill to check if you qualify?”	A way to get your account number and anchor the pitch
“You’ll get the 30% tax credit”	False for any cash or loan purchase installed in 2026. See 30% tax credit claims
“Your bill will be zero”	Almost never true. See zero bill promise

What never to share at the door

Keep these to yourself until you’ve chosen an installer on your own terms:

• Your electric bill. It contains your utility account number, service address, meter number and usage history. With that information, a company can start interconnection or enrollment paperwork.
• Your utility account number or login, even read aloud.
• Your Social Security number or date of birth. These are used to run credit checks for loans and leases. A “soft check to see if you qualify” is still the start of a financing application.
• Any signature on a tablet or phone. “Just sign so we can check your roof” or “this only confirms I was here” can be a contract, a credit application or a utility authorization. If you can’t read the whole document on a full screen at your own pace, don’t sign it.
• Photos of your meter or electrical panel. A legitimate installer will do a proper site visit after you’ve agreed to get a quote.

Watch out: “Sign here so I can show my manager” and “this isn’t a contract” are among the most common lines in solar complaints. Treat every signature request as a binding agreement, because it may be one.

Scripts to end the conversation

You don’t owe anyone an explanation. Pick one and repeat it.

• The firm no: “I’m not interested. Please don’t come back.”
• The no-bill: “I don’t share my bill or account information at the door. Leave a card and I’ll reach out if I want a quote.”
• The process answer: “We get at least three written quotes before any home project. Email me a proposal with the cash price, system size and equipment models, and I’ll compare it.”
• The not-today: “I don’t make financial decisions the same day. If the price won’t hold until next week, it’s not for me.”
• The verification: “Which utility department are you with? I’ll call the number on my bill to confirm.” (If they claim a utility connection, do exactly that.)
• If they keep pushing: “I’ve said no. I’m closing the door now.” Then close it.

If someone refuses to leave, you can call your local police non-emergency line.

If you’re actually interested in solar

A knock can be a reasonable nudge to look into solar. Just switch to a process you control:

1. Ask for a written proposal by email, not a tablet presentation. It should list the cash price, system size in kW, price per watt, exact panel and inverter models, production estimate, warranty terms and who installs.
2. Get two or three more quotes, including one from a local installer that uses its own crews. Compare them with our quote comparison tool and read how to compare solar quotes.
3. Run your own numbers in the solar calculator. For 2026 purchases, use $0 for the federal tax credit.
4. Check the financing. If a loan is offered, ask for the cash price and use the dealer fee calculator. If it’s a lease or PPA, read lease vs buy vs PPA vs loan and look for an escalator.
5. Check the license with your state contractor board. Your state page lists the license type and lookup link where we have it.
6. Test the pitch. Paste the claims you heard into our sales claim checker.

If you already signed: the 3-day cooling-off rule

The FTC’s Cooling-Off Rule (16 CFR Part 429) covers most sales of $25 or more made at your home, including leases. Under the rule:

• You can cancel until midnight of the third business day after the sale. Saturdays count as business days. Sundays and federal holidays do not.
• The seller must tell you about your right to cancel at the time of sale and give you two copies of a cancellation form, plus a copy of the contract that shows the date and the seller’s name and address.
• You don’t need a reason to cancel.
• After you cancel, the seller generally has 10 days to refund your money and return anything you traded in or signed, such as a promissory note.

Some states add more time or protections. For example, California gives buyers 65 and older five business days to cancel a home solicitation sale and bars work from starting during that period. Rules vary, so check your state attorney general’s website or our state pages.

Send your cancellation in writing in a way you can prove, such as certified mail with a return receipt, and keep a copy. Our cancel a solar contract guide includes a template letter, and the cancellation tool helps you count the days.

Don’t let anyone talk you out of cancelling by starting work, delivering equipment, or saying the rule doesn’t apply to solar. A seller pressuring you to waive your right to cancel is a red flag on its own. See cooling-off waiver.

Extra care for older homeowners and family members

Retirees are a frequent target. A pitch built around a tax credit is especially misleading for someone with little tax liability, and for 2026 installs there’s no homeowner credit at all. If you have an aging parent, consider agreeing on a simple household rule: no signatures on any home project without a 48-hour wait and a call to a family member. Our guide to solar for retirees and the targeting seniors page cover this in more depth.

Reporting a pushy or deceptive salesperson

• Misrepresentation or Cooling-Off Rule violations: ReportFraud.ftc.gov
• Deceptive sales practices under state law: your state attorney general’s consumer protection office
• Loan problems: the CFPB complaint portal
• Someone claiming to be from your utility: the customer service number on your bill
• Ignoring a no-soliciting ordinance: your city or town clerk or police non-emergency line

Write down the company name, the rep’s name, the date and what was said while it’s fresh. For a fuller list of tactics and where to report each, see our solar scams guide.
