Solar panel scams and the tactics behind them
Most solar scams are not fake panels — they are real panels sold with a fake price: lender fees buried inside the system cost so a low interest rate looks free, leases marketed as “free solar”, modelled production quoted as a guarantee, a federal tax credit subtracted that ended after December 31, 2025, and a same-day signature demanded so none of it gets read.
Why solar attracts this
Three things about rooftop solar make it unusually good ground for a bad sale. It is expensive, so a few percent of margin is worth a lot of pressure. It is technical enough that most buyers cannot check the numbers on the spot. And it is sold overwhelmingly on commission, often by dealers who do not install anything themselves and are paid on the contract rather than on how the system performs in year seven.
None of that makes solar a bad purchase. On the right roof, in a high-rate state, it is still one of the better financial decisions available to a homeowner. It means the purchase has to survive a sales process that is designed not to be checked, and the way you survive it is to slow it down.
The tactics, and what to say back
These are the moves. None of them are subtle once you have seen them written down, which is most of the reason to write them down.
The utility-adjacent opener
The knock does not start with a company name. It starts with something that sounds official: a survey, a check on your bill, a programme in your area, a new rate everyone is being moved to. The uniform is neutral, the clipboard does a lot of work.
What to say: Ask which company employs them and whether they are an installer or a dealer. Real answers come immediately. If someone will not name their employer in the first sentence, there is nothing after that sentence worth hearing.
The neighbourhood proof
Your street is already doing it. There are panels three doors down, and the crew is out here anyway, so the price is better this week.
What to say: Panels on a neighbour's roof tell you about a neighbour's roof. Ask for the address and permission to speak to them. The bluff usually folds here.
The expiring price
A discount that lives until the end of the visit. A batch, a block, an allocation, an incentive with a deadline nobody can produce documentation for.
What to say: Any price that expires when the salesperson leaves your house was never a price. A genuine rebate has a program name you can look up on DSIRE, and it will still be there tomorrow.
The credit that no longer exists
A proposal with 30% subtracted and "federal tax credit" written next to it. The residential credit under IRC Sec. 25D ended for property placed in service after December 31, 2025, so on a system installed now that line is worth nothing.
What to say: Ask them to write the statute number beside the line. Then ask what the payback looks like with that line removed, because that is your actual deal.
Payment instead of price
The whole conversation happens in dollars per month. The system price is never said out loud. Your current bill is compared against a solar payment, and the difference is called savings.
What to say: Ask three questions: what is the gross price, what is the price per watt, and what is the total of all payments over the full term. The third number is usually the one that ends the meeting.
The fee inside the interest rate
A very low advertised APR on a long loan. The lender charges the installer to buy that rate down, and the installer puts that cost into the system price. Industry reporting has put these dealer fees at a substantial share of system cost — enough to move a quote by thousands.
What to say: Ask for the cash price and the financed price for the identical system, in writing, on the same day. If they differ, the gap is the fee, and now you can decide whether you want to pay it.
Escalators in the fine print
A lease or PPA payment that rises a fixed percentage every year for twenty-plus years. Year one looks great against your current bill. Year fifteen is a different document.
What to say: Ask for the payment schedule for every year of the term, as a table. Then compare the total against the cash price of the same system. Do not accept a verbal 'it is about the same'.
Production presented as a promise
A modelled annual kWh figure, delivered as if it were guaranteed, from software that has not seen your shade.
What to say: Ask whether the production estimate is guaranteed, what happens if the system underproduces, and who pays. If the answer is a shrug, treat the estimate as marketing.
The tablet signature
Documents signed on a screen, scrolled quickly, with the salesperson narrating what each page says. The buyer never sees the full contract before the signature.
What to say: Nobody has ever lost money by taking the PDF away and reading it overnight. If a same-day signature is required, the requirement is the red flag, not the timing.
The roof nobody looked at
A quote produced from satellite imagery, with no attic inspection, no discussion of roof age, and no mention of what happens when the roof needs replacing under a twenty-five-year array.
What to say: Ask how old the roof is and what removal and reinstallation of the array would cost. If the roof has under ten years left, that cost belongs in your payback maths now, not in a decade.
Where the money actually hides: dealer fees
This is the single most expensive thing most solar buyers never learn about, so it is worth spelling out mechanically.
A lender offers solar loans at rates far below what an unsecured twenty-year consumer loan would normally carry. Somebody pays for that gap. The lender charges the installer a fee to originate the loan at the advertised rate, and the installer puts that fee into the price of the system. You do not see it as a fee. You see it as the price.
The mechanism is legal and disclosed somewhere in the paperwork. The problem is that it is invisible at the point of decision, and it means a homeowner comparing a 1.99% solar loan against a 7% home equity loan is not comparing what they think they are comparing. Industry reporting has put these fees at a large enough share of system cost to move a quote by thousands of dollars.
| What you are shown | What is actually happening |
|---|---|
| A very low APR | The rate was bought down. The cost of buying it down is in your system price. |
| One price, financed | There is usually a lower cash price for the same equipment. |
| A monthly payment | Total of payments over the term is the real price. Multiply it out. |
| 'No dealer fee' | Then the cash and financed prices will be identical. Ask for both, in writing. |
Ask for both prices in one email. “Please send the cash price and the financed price for the identical system, including the total of all payments over the loan term.” A company that will not answer that in writing has told you the answer.
“Free solar” is a lease or a PPA
When a pitch leads with no money down and no cost, it is almost always one of two arrangements. In a lease you rent the equipment for a monthly payment. In a power purchase agreement you buy the power the system makes, at a per-kWh rate, from the company that owns the panels on your roof. Terms typically run twenty to twenty-five years and often carry an annual escalator.
Neither is fraud. Both can suit someone with no cash and no tax appetite. But three things follow from not owning the system, and they are rarely in the opening pitch.
You do not get the tax treatment. The system owner does, at the business level, and whatever that is worth reaches you only as whatever they priced into your payment. Second, selling the house gets more complicated: the buyer has to assume the agreement or you have to buy it out, and there is often a filing against the property that has to be dealt with at closing. Third, the escalator. A payment that rises every year for two decades, compared against a bill you assume will rise too, is a bet — and the pitch always models your utility rising faster than your payment.
The comparison that settles it is boring and decisive: total of all payments over the full term, against the cash price of the same system. Do that arithmetic before you look at anything else in the proposal.
What to demand in writing
- 01The company’s legal name and contractor licence number — and whether they install the system themselves or subcontract it. Dealers and installers are not the same business, and the warranty usually lives with whoever holds the licence.
- 02System size in kW DC, and the make and model of panels and inverters. Not “premium tier”. Model numbers.
- 03Gross price and price per watt, before any incentive is subtracted. This is the only number that compares across quotes.
- 04Cash price and financed price side by side, plus the total of all payments over the term. The gap between them is the finance cost, whatever it gets called.
- 05Every incentive itemised with its program name, so you can look each one up. If a federal credit appears on a proposal for a system being installed now, ask for the statute.
- 06The production estimate, with a statement of whether it is guaranteed and what the remedy is if the system underproduces.
- 07Roof age, condition, and the cost to remove and reinstall the array if the roof is replaced during the system’s life.
- 08Warranty terms, separately: panels, inverter, workmanship, and roof penetrations. These are four different warranties from up to four different parties, with four different lengths.
- 09What your utility will pay for exported power, and for how long those terms are locked. This decides a large part of your payback and it is not the installer’s choice.
- 10The cancellation window and how to use it, in the contract, not verbally.
Every item on that list is something a competent installer produces without complaint, because they have it already. The list is not a test of the company’s honesty so much as a test of whether they are set up to sell to a buyer who reads.
Rules of thumb worth keeping
Never sign the day someone knocks
Get three quotes, and compare per watt
Never let a stranger run a hard credit check in your hallway
Ask who holds the workmanship warranty in five years
Take the whole document set away and read it
Common questions
Are solar panels a scam?
The panels are not. The sales process frequently is. Rooftop solar is a well-understood technology with a long warranty life, but it is sold door to door and by phone on commission, and a large share of the complaints homeowners file are about the sale rather than the hardware: fees buried in loan pricing, savings and production figures presented as promises, contracts signed on a tablet the buyer never read, and a federal tax credit quoted that no longer exists.
What is a solar dealer fee?
It is what a lender charges an installer to originate a low-rate solar loan, and the installer adds it to your price. The advertised rate looks low because the cost of buying that rate down has been moved into the system price. It is real, it is common, and it is why the same system is often materially cheaper in cash than financed. Ask for the cash price and the financed price side by side; the gap is the fee.
Is free solar real?
No. A pitch offering solar with nothing down and no cost is describing a lease or a power purchase agreement. You do not own the system; a third party does, and you pay them monthly for the power or for the equipment, usually for twenty to twenty-five years, often with an annual escalator that raises the payment every year. It can still be a reasonable arrangement. It is not free, and calling it free is the tell.
How do I know if a solar quote is legitimate?
A legitimate quote states the system size in kW, the panel and inverter make and model, the gross price, the price per watt, and every fee, on paper, with a company name and licence number. It does not require a same-day signature, does not lead with a monthly payment instead of a price, and does not subtract a federal tax credit for a 2026 installation, because there is not one.
Should I let a solar salesperson run my credit?
Not on the doorstep and not to 'see what you qualify for'. A soft check to show pricing does not need your full identity and does not need to happen while someone is standing in your hallway. Once a hard application is submitted, the conversation shifts from whether you want solar to which loan you are taking, which is precisely the point of doing it early.
What should I do if I already signed?
Read your contract for the cancellation window — many states give a three-day right to cancel a door-to-door sale, and it is triggered from the signing date, so do it today rather than tomorrow. Send the cancellation in writing, by the method the contract specifies, and keep proof of sending. If the window has closed, get the full document set and have someone who is not selling you anything read the finance terms.
