Most solar panel scams have nothing to do with the panels. The hardware on your roof is mature, boring, and reliable. Where people actually get hurt is the sales pitch and the financing paperwork stapled to it: the door-to-door rep who lies about who he works for, the “free solar” that turns out to be a 25-year lease, the dealer fee buried inside a “low APR” loan. If you learn to read those red flags, you can still buy solar and come out ahead. This is a catalog of the real tactics owners report, in their own words, plus a checklist to protect yourself and your parents.

What are the most common solar panel scams?
The most common solar panel scams are deceptive sales tactics, not defective equipment: reps who lie about representing your utility, “free solar” pitches that hide a lease or loan, fake savings promises of a $0 bill, dealer fees baked secretly into financing, and pressure aimed at elderly homeowners. The panels usually work. The deal around them is where the money leaks.
That is the pattern once you read enough owner complaints. Nobody is posting that their cells stopped making electricity. They are posting about a contract they didn’t understand, a fee nobody disclosed, or a salesperson who vanished the moment the ink dried. So let’s go tactic by tactic.
The door to door solar scam: he does not work for the utility
The classic door to door solar scam starts with a lie about identity. A rep shows up, implies or flatly claims a connection to your power company, and dangles something free to get inside. It sounds official, which is the whole point.
One person described exactly this: a rep who “claimed to represent the utility company” and pitched “free” solar. When they turned him down, the friendly act dropped fast, and he “became hostile” over text afterward.
“claimed to represent the utility company” … “became hostile”
Source: The Cool Down. Your utility does not send commissioned salespeople door to door to sign you up for rooftop panels. That framing is a trust hack, and the hostility after a “no” tells you what the interaction was really about. A legitimate installer is happy to have you call back next week. A closer working a quota is not.
Why do salespeople target elderly homeowners?
Because it works, and because the contracts run for decades. This is the ugliest corner of the whole business, and it is the reason adult children need to pay attention to what gets pitched at their parents’ front doors.
In one case, an 80-year-old man with cognitive decline was signed onto a 25-year Sunrun lease at “$300/month” with a “2.99% escalator,” meaning the payment climbs every single year for a quarter century. The detail that should bother everyone came from a former salesman describing how the con compounds itself:
“I would have elderly people tell me about a prior solar salesperson who told them about some elderly program or other, which is completely false information.”
Source: The Cool Down. There is no secret “elderly program.” It is a fabricated hook invented to close a sale, and it gets passed from one rep to the next like folklore. An escalator clause on a 25-year term is how a payment that sounded fine on day one becomes crushing by year fifteen, long after the salesperson is gone.
The “$0 electric bill” promise that never shows up
The savings pitch is where hope does the selling. Reps promise your electric bill disappears, the panels pay for themselves, and you basically get power for nothing. Then reality sends a bill anyway.
An Oregon consumer PSA warned that people get “sold on an idea of massive savings that never materialize.” It is common enough that regulators are suing over it. New York City has taken a solar company to court for allegedly making false promises, including one that “promised $0 electric bills.”
“sold on an idea of massive savings that never materialize”
Sources: The Cool Down and Yahoo Finance. Solar can cut a bill hard, sometimes dramatically. But “zero, guaranteed” ignores fixed grid connection charges, seasonal production swings, and rate changes. When a number sounds too clean, it usually skipped the fine print on purpose.

Solar dealer fees: the markup hiding inside a low APR
Here is the one that catches even careful buyers. Those “0.99% APR” and “1.99% APR” solar loans are not charity. The lender’s cost gets recovered through a dealer fee, a hidden markup added to the system price, and it is often 20 to 30 percent of the total. You rarely see it as a line item. It just makes the price bigger.
A Pennsylvania homeowner went digging through his paperwork and found a “$2k ‘rate fee'” that the “installer is currently refusing to discuss.” Worse, the installer’s math also appeared to short his 30% federal tax credit by roughly $1,200 by calculating it off the wrong number.
“$2k ‘rate fee'” that the “installer is currently refusing to discuss”

This is why a cash price and a financed price should always be compared side by side, because the gap between them is the dealer fee in plain sight.
Are online reviews enough to vet a solar installer?
No, and this one stings because reviews feel like due diligence. Star ratings are gameable. Fake reviews are cheap, and a company can look spotless online while being anything but.
One buyer did what we all do, checked the ratings, and got burned anyway. The installer “had great reviews on Google,” and the buyer only “later found out he is a fraud.”

Source: The Cool Down. Reviews are a starting point, not proof. License status, bonding, and years in business are harder to fake and tell you far more than a row of five-star clicks.
Legitimate solar still exists, and the buyers know it
None of this means solar is a scam. It isn’t. The people who warn hardest about bad actors are usually the same owners who love their systems and want you to have a good one too. Their advice is not “never buy.” It is “buy the right way.”
The fix they point to over and over is comparison shopping instead of trusting a door-knock: get multiple quotes and run them through a neutral marketplace like EnergySage so you can compare real numbers rather than a pitch. Source: The Cool Down. A rep at your door wants a signature tonight. A good installer will still be there next week when you’ve compared three bids.
How to avoid solar scams: a defense checklist
Almost every story above could have been stopped by slowing down and checking a few specific things. Here is the checklist, and it doubles as the one to run when you sit in on a pitch made to your parents.
- Never sign on the doorstep. No legitimate deal expires because you wanted a night to read it. Same-day pressure is the tell.
- Treat “free solar” as a lease, loan, or PPA in disguise. The panels are never free. Ask which one it is and who owns the system, then read that contract term by term.
- Get three or more quotes and compare dollars per watt. One number in isolation means nothing. Three lets you see who is padding.
- Hunt for the dealer or rate fee inside “low APR” loans. Ask for the cash price and the financed price on the same system. The difference is often 20 to 30 percent, and that is the hidden markup.
- Avoid or cap escalator clauses. A 2.9 to 2.99 percent annual escalator quietly balloons a payment over a 20 to 25 year term. A flat payment is almost always better.
- Ignore fake urgency. “The utility will disqualify you” and “this rebate ends tonight” are scripts, not facts.
- Verify license, bonding, and years in business, not star ratings. Reviews get faked. A license number and a bond do not.
- Know your three-business-day right to cancel. Federal rules give you a cooling-off window on most door-to-door sales. Use it if your gut turns.
- Understand the tax credit is a nonrefundable credit, not a check. It reduces tax you owe. The government does not mail you a refund for it, and a rep who says otherwise is wrong or lying.
- Sit in on pitches made to elderly relatives. There is no “elderly program.” A second set of eyes stops most of this cold.
Frequently asked questions
Is a door-to-door solar salesperson from my utility?
Almost never. Utilities do not send commissioned reps to sign you up for rooftop panels. If someone claims a utility connection at your door, treat it as a red flag and verify by calling your utility directly using the number on your bill.
What is a solar dealer fee?
It is a hidden markup lenders add to the system price to fund those very low advertised APRs, often 20 to 30 percent of the total. Ask for the cash price and the financed price on the same system. The gap between them is the dealer fee.
Is “free solar” real?
No. “Free solar” is marketing for a lease, loan, or power purchase agreement. You either pay for the system or pay a company for the power it makes. Find out which one you are being offered and who owns the panels.
How do I protect an elderly parent from a solar scam?
Sit in on the pitch, get everything in writing, and get multiple quotes before anyone signs. Watch specifically for long lease terms, annual escalator clauses, and claims about special “programs” for seniors, which do not exist.
If you take one thing from all of this, make it this: the panels are rarely the problem, so put your scrutiny on the contract and the closer, not the roof. Get three quotes, read the financing line by line, and never let urgency make the decision for you. Buy that way and solar can still be a genuinely good deal. Let a door-knock rush you and it becomes the most expensive thing on your house.
