12 Solar Sales Red Flags to Watch For in 2026

The short answer: most solar sales red flags come down to one thing — the person in your living room is paid a commission that comes out of your price, and they often don't work for the company that will install or service your system.

That doesn't make every rep dishonest. It does mean the incentives are pointed at getting a signature tonight, not at getting your math right. The 12 signals below are the ones that most often precede a bad solar deal, and every one of them has a simple, non-confrontational question you can ask to test it.

If you take nothing else from this page: no legitimate solar offer expires tonight. Any rep who tells you otherwise has just told you what kind of rep they are.

Why Solar Attracts High-Pressure Sales in the First Place

Most reps don't work for the company installing your system

A large share of residential solar is sold through a dealer network. An installer sets a base price, then independent sales organizations — and the 1099 reps under them — market that installer's systems in exchange for the margin above that base.

The industry term for the base price is the redline. It's the price per watt that has to go to the installer, the dealer, and the sales manager. Anything the rep can charge you above the redline is, in effect, their paycheck.

Two consequences follow:

The rep has a direct financial interest in your price being higher.
The rep may have no long-term relationship with the company that has to honor your 25-year warranty.

Neither is illegal. Both are worth knowing before you sit down.

The rep's pay comes out of your price

This is the part almost nobody says out loud. In its review of the solar financing market, the Consumer Financial Protection Bureau found that hidden fees baked into solar loans — variously labeled "dealer fees," "program fees," "lending fees," or "platform fees" — typically run 10% to 30% of the cash price, and can exceed 50%.

The CFPB's own example: a $30,000 solar project carrying a 30% fee becomes a $39,000 loan principal, with the lender keeping the $9,000 markup. The homeowner sees a low interest rate and never sees the $9,000.

So when a rep is unusually eager to move you onto financing, or waves off the question of what the cash price is, you're seeing the mechanism — not a personality quirk.

The 12 Red Flags

1. "This price is only good if you sign today"

Why it's a flag: solar equipment pricing doesn't move hourly. Permits, interconnection queues, and utility rate schedules don't reset at midnight. A one-night-only price is a manufactured deadline designed to prevent you from getting a second quote — which is the single most effective thing you can do to lower your price.

Connecticut's Attorney General has repeatedly cited high-pressure tactics and misrepresentations in enforcement actions against solar companies, including a $5 million judgment against Vision Solar. Texas went further: Senate Bill 1036, effective September 1, 2025, now governs what can and cannot be said during a residential solar sales pitch and specifically targets door-to-door and high-pressure solar sales.

Ask this: "Send me the same proposal in writing and I'll compare it this week. If the price changes by Friday, I'll know what that means."

A real rep says yes. The deadline evaporates almost every time.

2. Big tax-credit promises — especially the 30% federal credit

This is the most important item on this page in 2026.

The 30% federal residential solar tax credit (Section 25D) expired on December 31, 2025 under the One Big Beautiful Bill Act. It does not exist for residential systems installed in 2026, and the IRS has published guidance confirming the accelerated termination.

If a rep in 2026 tells you the federal government will give you 30% back on a home solar purchase, one of two things is true: they haven't read the law, or they're counting on you not having read it. Either way, that number is being used to make a payment look survivable that otherwise wouldn't.

Watch for the softer versions too:

"There's still a credit, it's just structured differently."
"We take the 30% right off the top so your loan is smaller."
"You'll get it back at tax time and use it to pay the loan down."

That last one is the classic. The CFPB flagged exactly this pattern: salespeople present the credit as guaranteed, subtract it from the quoted "net cost" in large type, and show the real loan amount in small type — while, in the CFPB's words, "lenders and installers seldom if ever know the consumer's tax situation."

What is still real in 2026: state and utility rebates, performance incentives and SRECs in some states, net metering credit, sales and property tax exemptions, and — for leases and PPAs — the commercial Section 48E credit, which flows to the system owner, not to you. Those are legitimate. A 30% federal check to a homeowner is not.

Ask this: "Show me the statute or the state program page for every incentive on this proposal."

3. "Don't worry, we have a CPA who handles all that"

Why it's a flag: a solar company's "CPA" is not your CPA. They have no visibility into your federal tax liability, your withholding, your filing status, or your carryforwards — and no obligation to you if the number is wrong.

Tax credits are non-refundable and liability-limited. A homeowner with little or no federal tax liability — many retirees, for example — could never have used the full residential credit even when it existed. The CFPB specifically identified aggressive targeting of older homeowners in solar financing, noting that between 2020 and 2021, 44% of older homeowners with solar financed the purchase, versus 36% of younger homeowners.

Ask this: "Will you put in writing that this tax outcome is guaranteed, and that you'll cover the difference if it isn't?"

Nobody will. That's the answer.

4. The rep can't tell you who actually employs them

Why it's a flag: not because 1099 work is wrong — plenty of good salespeople are independent contractors. It's a flag because you need to know which company is on the hook for your system in year 12.

When a rep can't produce a business card, an email address on a company domain, or a straight answer to "who signs your paycheck," you're usually dealing with a chain: an installer, a dealer, a sales org, and a rep — and any link in that chain can disappear. Vision Solar's $5 million Connecticut judgment went largely unpaid because the company went bankrupt.

Ask this: "Which company's name goes on the installation contract, and which one holds the workmanship warranty? Are those the same company you work for?"

Then verify it. In Texas, residential solar retailers and salespersons must register with the Texas Department of Licensing and Regulation under SB 1036. Most states require the installing contractor to hold an electrical or specialty contractor license you can look up online.

5. They're a broker — and you're being sold whatever pays best

Why it's a flag: a rep with three or four installer relationships is often described as giving you "options." Sometimes that's true. But if the rep is compensated differently by each installer, the recommendation is shaped by their spread, not by which installer does the best work in your county.

Brokering isn't inherently bad — mortgage brokers exist and serve people well. The difference is that in solar, the spread is usually invisible to you.

Ask this: "How many installers do you sell for, and are you paid the same on each one?"

The answer to the second half is almost always no. What matters is whether they'll say so.

6. They got in your door under a different pretext

Why it's a flag: if the conversation didn't start as a solar sales conversation, everything after it is compromised.

What they say at the door	What it usually is
"We're doing a quick energy audit in the neighborhood"	A solar sales appointment
"I'm just verifying whether your roof qualifies for the program"	A solar sales appointment
"There's a state program ending and I need to check your eligibility"	A solar sales appointment
"I'm with the utility / here about your rate"	Almost never the utility
"Your neighbors already signed up, I just need your meter number"	A pitch plus a data grab

Connecticut's Attorney General has taken action against solar companies for locking consumers into long-term contracts without their consent. Pretextual entry is how that starts.

Do this: ask for a company name and a callback number, then end the conversation and call the utility or the company directly. A legitimate program survives a five-minute delay.

7. They've been in solar for months, not years

Why it's a flag: residential solar has always attracted high-churn commission sales. Every time an incentive deadline hits the news, a wave of new reps arrives — and a wave leaves when the deadline passes.

Tenure isn't a character test. It's a competence test. A rep who has never seen a system through permitting, inspection, interconnection, and a first true-up bill cannot tell you what your first year will actually look like, because they've never watched one happen.

Ask this: "How many systems have you personally sold that are now switched on and producing? Can I talk to one of those homeowners?"

8. Desperation in the room

Why it's a flag: reps who mention their quota, their manager, their rent, or how badly they need this one are — knowingly or not — moving you from an evaluation into a favor. It's effective, and it has nothing to do with whether solar is right for your roof.

The same applies to the reverse: reps who won't leave, who reopen the conversation after you've said no, or who ask to "just use your bathroom" or "call my manager real quick" to reset the clock.

Do this: "I've decided not to decide tonight" is a complete sentence. You don't owe an explanation.

9. No written proposal you're allowed to keep

Why it's a flag: verbal solar math is unfalsifiable. If everything lives on a tablet the rep takes with them, you cannot compare quotes, show it to a spouse, or prove what you were told.

A proposal you can keep should show, in writing:

System size in kW DC, and the panel and inverter make and model
Total cash price and price per watt
Year-one production estimate in kWh, with the shading and tilt assumptions used
Every incentive, itemized, with its source
If financed: APR, term, total of payments, and the dealer fee
Any escalator — a lease or PPA rate that rises annually, commonly 0.99% to 2.99%
Who holds the workmanship warranty, and for how many years

10. The savings number has no assumptions attached

Why it's a flag: "you'll save $67,000 over 25 years" is not a number, it's a mood. It depends entirely on an assumed utility rate escalation, which reps routinely set at 4% to 6% per year compounding — a rate that, applied for 25 years, roughly triples your bill on paper and makes almost any system look like a win.

Ask this: "What annual utility rate increase did you assume, and what does this look like at 2%?"

If the savings collapse at 2%, the savings were the assumption, not the system.

11. A credit application before you agreed to one

Why it's a flag: some reps run a "soft pre-qualification" that turns out to be a full application, or ask for your Social Security number early "to see what tier you're in." Once you're approved, the psychological frame shifts from should I to which payment.

Do this: don't provide a full SSN, a utility account number, or a signature on a tablet until you have the written proposal in hand and have compared it to at least one other.

12. Nobody mentions the dealer fee

Why it's a flag: see the CFPB findings above — 10% to 30% of the cash price, sometimes more, buried in the loan principal. A rep who has never used the phrase "dealer fee" in a two-hour presentation about financing is not having an accidental oversight.

There's a fast way to expose it. Ask for the cash price and the financed price side by side. The gap is the fee.

Green Flags: What a Legitimate Solar Rep Does

Not everyone knocking on your door is a problem. Here's what the good ones do:

Leaves the proposal with you and follows up in a week, not in an hour
Names the installing company and can say how long they've been in your market
Shows their license or registration number without being pushed
Asks to see 12 months of bills, not one summer bill
Talks about the roof — its age, its condition, whether it needs replacing first
Says "this might not make sense for you" at least once, and means it
States assumptions out loud — escalation rate, panel degradation, production estimate source
Explains net metering in your specific utility territory, not "net metering" in general
Volunteers the dealer fee, or offers a cash price for comparison

7 Questions to Ask Before You Sign Anything

Print this. Ask them in order.

Which company's name is on the installation contract, and do you work for that company?
What is the cash price, and what is the financed price? The difference is the dealer fee.
What utility rate escalation did you assume in the savings number?
Which incentives on this proposal are guaranteed, and which depend on my tax situation?
Who holds the workmanship warranty, for how many years, and what happens if you go out of business?
What's my production guarantee in kWh, and what do you pay me if it underperforms?
May I keep this proposal and call you Friday?

Question 7 is the one that does the most work.

What to Do If You Already Signed

You may have more time than you think.

Federal: the FTC's Cooling-Off Rule (16 CFR Part 429) gives you three business days to cancel most sales over $25 made at your home, and requires the seller to give you written notice of that right. If they never gave you the cancellation form, that's a violation in itself.
Texas: SB 1036 gives homeowners five business days to cancel a residential solar contract without penalty. Violations carry penalties up to $2,500 per incident, and $10,000 per violation where a senior citizen is affected — and the regulator may cancel the contract and order refunds.
Every state: your state Attorney General's consumer protection division takes solar complaints, and several are actively litigating. Connecticut's AG has pursued Vision Solar, Spruce Power, SunStrong and others. Texas sued CAM Solar in May 2026 after more than 100 consumer complaints.

Frequently Asked Questions

Is door-to-door solar a scam?
No — door-to-door is a sales channel, not a fraud. Legitimate installers use canvassing. But because door-to-door reps are usually paid the spread above a base price and often work for a dealer rather than the installer, the channel concentrates high-pressure behavior. Judge the offer, not the doorbell.

Is the 30% federal solar tax credit still available in 2026?
No. The Section 25D residential clean energy credit expired December 31, 2025 under the One Big Beautiful Bill Act. Any 2026 sales pitch built on a 30% federal credit for a homeowner purchase is wrong. State and utility incentives, net metering, and tax exemptions still exist and vary by state. See our 2026 tax credit guide.

How long do I have to cancel a solar contract?
At least three business days under the FTC's Cooling-Off Rule for sales made at your home. Texas allows five business days under SB 1036. Some states and lenders allow more. Cancel in writing and keep proof of the date.

What is a solar dealer fee?
A markup added to the price when you finance rather than pay cash. The CFPB found these fees typically run 10% to 30% of the cash price and sometimes exceed 50%, often labeled as a program fee, platform fee, or lending fee. They're rolled into the loan principal, so a low advertised APR can still mean a much larger balance. See Solar Financing Options in 2026.

Should I be worried that my solar rep is a 1099 contractor?
Not by itself. What matters is whether you can identify the company that will install the system, hold the workmanship warranty, and answer the phone in year 10 — and whether that company is licensed in your state.

How do I check if a solar company is legitimate?
Verify the contractor license with your state licensing board, check your state Attorney General's press releases and complaint records, look up the company's history under prior names, and confirm the installer's own warranty terms in writing. In Texas, residential solar retailers and salespersons must also be registered with the Texas Department of Licensing and Regulation.

What's a realistic utility rate increase to assume in a solar savings estimate?
Many proposals assume 4% to 6% annual utility rate escalation compounding for 25 years, which roughly triples your bill on paper and makes almost any system look like a win. Ask any rep to re-run your savings at 2%. If the deal only works at 5%, the deal is the assumption, not the system.
