The Inflation Reduction Act sent $369 billion into clean energy, and solar scammers are following the money. The Federal Trade Commission logged a 73% increase in solar-related complaints between 2022 and 2025. Solar Outreach Partnership surveys show 1 in 5 homeowners who received a solar quote in 2025 reported feeling pressured or misled. In a market where a typical system costs $25,000–$45,000 — before incentives — falling for a bad actor can cost you tens of thousands of dollars.
This guide covers every major solar fraud tactic active in 2026, a 10-point red flag checklist you can run in 10 minutes, and the exact steps to verify any installer before you sign.
Why Solar Scams Are Accelerating in 2026
Three forces have made the solar industry a magnet for fraudsters:
1. The IRA incentive surge. The 30% federal Investment Tax Credit — and the 40% Energy Community bonus for buyers in qualifying census tracts — have created a wave of "too-good-to-be-true" pitches. Scammers impersonate government representatives and pitch "free solar from Biden's clean energy program." There is no free-solar government program. The ITC is a tax credit — you claim it on your tax return, and it reduces what you owe.
2. Rapid industry growth. U.S. solar installed 16+ GW residentially in 2025 — a record. Fast-growing markets attract undercapitalized installers who take large deposits, complete shoddy work, and fold before honoring warranties. The NABCEP (North American Board of Certified Energy Practitioners) estimates that 30–40% of residential solar installs are done by installers with no NABCEP-certified staff.
3. Door-to-door sales pressure. Most legitimate top-tier installers (Sunrun, SunPower, Freedom Forever) use door-to-door canvassing. So do most fraudulent operators. The channel itself isn't a red flag — but the tactics used once you open the door often are.
The 9 Most Common Solar Scam Types
1. Government or Utility Impersonation
The pitch: "I'm with the Department of Energy" or "Your utility sent me to audit your roof for the new solar program." The rep may wear a polo shirt with a government-adjacent logo, carry official-looking paperwork, and reference your utility account number (available in breach databases).
The truth: Government agencies do not send door-to-door solar reps. USDA REAP, WAP, and other programs are applied for through licensed contractors — not announced by unscheduled house calls. Your utility company will not cold-visit your home to offer free solar.
What to do: Ask for a business card, look up the company independently (not the number they give you), and hang up or close the door. Never give them your utility account credentials.
2. "Free Solar" or "No Cost" Schemes
The pitch: "You qualify for free solar panels — there's no cost to you." This may be technically framed as a lease or PPA where you pay nothing upfront — but the 25-year contract that follows is anything but free.
The truth: Solar equipment costs money. "Free panels" either means a lease (where the installer keeps the ITC and charges you monthly for 25 years) or an outright fabrication. Legitimate zero-down options exist — solar loans, PPAs, and leases — but they come with clear terms in writing, and you never own the system.
What to do: If someone claims the panels are free without explaining exactly who owns the system, how you pay, and what happens when you sell your home, walk away.
3. Bait-and-Switch Equipment
The pitch: Your quote shows name-brand panels (SunPower Maxeon 6, REC Alpha, Panasonic EverVolt) with 25-year warranties. At installation, budget panels with no-name inverters show up on the truck.
The truth: Unless your contract specifies panel model numbers (not just brand names), installers can legally swap equivalent-or-better equipment. Unscrupulous installers swap in budget panels to improve their margin — and your contract may authorize it.
What to do: Before signing, verify the contract includes specific make, model, and wattage for panels, inverter brand/model, and racking brand. Use the Solar System Designer to understand what a correctly specified quote looks like.
4. Manipulated Production Estimates
The pitch: The production estimate shows you'll generate 120% of your annual usage — essentially eliminating your bill. This justifies a larger system at a higher price.
The truth: PVWatts (NREL's industry-standard production estimator) is the benchmark tool. Reputable installers use it with real shading data and conservative derate factors. Fraudulent installers cherry-pick ideal assumptions: no shading losses, peak system performance, inflated sun hours. A legitimate 10 kW system in Dallas typically generates 13,000–14,500 kWh/year. Padded estimates sometimes show 17,000+ kWh for the same location.
What to do: Ask the installer for their production report and what tool generated it. If they used PVWatts, ask to see the input parameters. Compare against the Solar Payback Period Calculator using your actual annual kWh consumption. A production estimate above 95% offset should be scrutinized closely.
5. Hidden Dealer Fees on Solar Loans
The pitch: "We have a 0% solar loan — no interest for 25 years!" or "We'll cover your interest with a rebate."
The truth: The solar industry's worst financing secret is the dealer fee. Lenders like Mosaic, GoodLeap, and Sunlight Financial charge solar installers a 20–30% dealer fee for each financed loan — a fee typically added to your loan principal. A system that should cost $28,000 gets sold for $35,000 because $7,000 of that is the dealer fee. When you claim the 30% ITC, you're claiming it on the inflated price — but the extra money went to the installer, not into your system.
What to do: Ask the installer: "What is the cash price vs. the financed price?" Any gap above 5–8% is a dealer fee. If they refuse to quote a cash price separately, take your business elsewhere. For more on financing, see Solar Financing Options 2026.
6. PACE Financing Ambush
The pitch: "There's no credit check — you just pay through your property tax bill." This describes Property Assessed Clean Energy (PACE) financing.
The truth: PACE puts a lien on your home — a senior lien that sits above your mortgage and HOA liens in the payment hierarchy. If you fail to pay your property taxes (which now include the PACE payment), the lender can foreclose. PACE also makes your home harder to sell: FHA and VA lenders will not close loans on homes with PACE liens in most states, and many conventional lenders require PACE payoff at closing. California regulators have imposed significant restrictions on PACE after documented predatory practices targeting elderly homeowners.
What to do: If you need financing, use a standard solar loan or home equity line of credit. If a rep pushes PACE and doesn't fully explain the lien implications, it is a serious red flag. For a full breakdown of financing risks, see Solar Financing Options 2026 and the Solar Energy for Seniors Guide.
7. The 25-Year Lease Trap
The pitch: "Zero down, no risk — just pay a small monthly fee." What they don't explain clearly is that the lease runs for 25 years, the installer owns the system (and claims the ITC), payments typically escalate 2–3% per year, and if you sell your home, the new buyer must qualify to assume the lease — or you must buy it out for $15,000–$30,000.
The truth: Leases are not inherently scams — some buyers genuinely benefit from them (renters who want to eventually own, buyers with no tax liability for the ITC, people who don't want any maintenance responsibility). The problem is when the lease terms are misrepresented or the escalator clause is buried in fine print.
What to do: Before signing a lease, read the full 20–25 page contract. Confirm the exact monthly payment, the annual escalation rate, the system size and production guarantee, the buyout schedule, and the home-sale transfer process. See Solar Lease vs. Purchase Guide 2026 for a full comparison.
8. Unlicensed Installers
The pitch: "We can start next week — the big companies have 3-month backlogs." Fast timelines can signal unlicensed operators who skip permits, skip electrical inspections, and do work that fails code.
The truth: A proper solar installation requires: (1) an electrical permit from your local jurisdiction; (2) an inspection by a building department official; (3) utility interconnection approval; and (4) Permission to Operate (PTO) from the utility before you can legally turn on the system. Unlicensed installers skip steps 1–3. You may have a system on your roof that has never been inspected, is not connected to the utility legally, and for which you cannot claim the ITC (because the system was never commissioned and granted PTO).
What to do: Before signing with any installer, ask: "Will you pull the permits and handle all inspections?" The answer must be yes. Unlicensed installers sometimes ask homeowners to pull permits themselves — a signal that the contractor is unlicensed. See Solar Permit and Inspection Process 2026 for the full legal timeline.
9. Ghost Installers (Take-the-Deposit and Disappear)
The pitch: A company collects a 10–25% deposit ($2,500–$8,000 on a typical system), schedules installation 6–10 weeks out, and then stops returning calls. The website goes dark, the phone is disconnected, and the company has filed for bankruptcy or simply dissolved.
The truth: This is the most financially devastating scam and has become more common as the market overheated in 2022–2024. Smaller installers with poor capitalization took large order books they couldn't fulfill.
What to do: Never pay more than 10% upfront before equipment arrives on-site. Use a credit card for all deposits (gives you chargeback rights). Verify the installer's state contractor's license is active before signing. Ask for business references from installations completed in the last 6 months in your area.
10-Point Red Flag Checklist
Run through this before signing any solar contract:
| # | Red Flag | What It Means |
|---|---|---|
| 1 | Can't produce a state contractor's license number | Likely unlicensed |
| 2 | Refuses to provide a cash price (only quotes financed price) | Hiding dealer fees |
| 3 | Contract doesn't specify panel model numbers | Bait-and-switch risk |
| 4 | Production estimate above 100% of your usage | Likely inflated |
| 5 | Pushes PACE financing without disclosing the lien | Predatory financing |
| 6 | No permit mentioned in the contract or timeline | Unlicensed/corner-cutting |
| 7 | "Government rebate" or "utility program" language that's vague | Impersonation |
| 8 | Contract pressures you to sign today or offer expires | High-pressure tactic |
| 9 | Deposit >10% before equipment is on-site | Ghost installer risk |
| 10 | No physical business address (only a PO box or no address) | Shell company |
How to Verify Any Solar Installer in 5 Minutes
Step 1: Check NABCEP Certification
The North American Board of Certified Energy Practitioners maintains a public lookup at nabcep.org. Look for NABCEP Photovoltaic Installation Professional (PVIP) certification. This doesn't mean every installer needs NABCEP staff — but larger companies should have at least one NABCEP-certified professional leading installation teams.
Step 2: Verify the State Contractor License
Every U.S. state has an online contractor license lookup. Search "[State] contractor license lookup" and verify the company name, license type (electrical contractor or general contractor, depending on state), and license status (active, not expired or suspended). The FTC reports that unlicensed contractors account for roughly 15% of solar complaints.
Step 3: Check BBB Rating and Complaint History
The Better Business Bureau (BBB) tracks complaints by company. Look for the pattern of complaints, not just the letter rating — a company with an A+ rating but 50 unresolved complaints in the last 12 months is a yellow flag. Solar-specific complaint patterns (no-show installations, billing disputes, equipment substitution) are significant.
Step 4: Verify SEIA Membership
The Solar Energy Industries Association (SEIA) requires members to commit to ethical marketing standards. Membership isn't a guarantee, but it provides accountability — SEIA has revoked memberships for repeated consumer complaints.
Step 5: Search "[Company Name] + scam" and "[Company Name] + complaints"
Google the company name followed by "complaints," "reviews," and "BBB." Check the subreddit r/solar — active homeowners post detailed experiences with specific installers. Check Yelp and Google Reviews for patterns (not just star ratings).
What to Do If You've Already Been Scammed
If you've already signed with a fraudulent installer or paid a deposit to a ghost company:
1. Stop payment immediately. If you paid by credit card, call your card issuer within 60 days to dispute the charge under the Fair Credit Billing Act. This is one of the strongest consumer protection mechanisms available.
2. File an FTC complaint. ReportFraud.ftc.gov is the FTC's consumer fraud reporting portal. Reports feed the FTC's Consumer Sentinel database, used by federal and state law enforcement.
3. Contact your state Attorney General. Most state AGs have consumer protection divisions that handle contractor fraud. Many states have contractor recovery funds that can reimburse victims of licensed-but-dishonest contractors. Unlicensed contractors may face criminal charges in your state.
4. File a CFPB complaint. If the fraud involved financing (solar loan, PACE lien), the Consumer Financial Protection Bureau at consumerfinance.gov/complaint handles lending-related complaints.
5. Contact SEIA. If the company is a SEIA member, file a complaint at seia.org. SEIA has expelled members for egregious consumer harm.
6. Consult a consumer protection attorney. Many states have contractor bond laws requiring installers to carry performance bonds — if the installer abandoned your project, the bond is designed to compensate you. An attorney can identify bond recovery options, potential class action membership if others were harmed, and state-specific remedies.
States With the Highest Solar Scam Activity (2025–2026)
Florida: The largest volume of FTC solar fraud complaints nationally. Florida has no state income tax credit to "give away," but scammers pitch a fictional "Florida solar credit" frequently. Florida's door-to-door solicitation rules are weak.
Texas: Scammers frequently impersonate Austin Energy or CPS Energy representatives. Texas's deregulated ERCOT market creates genuine confusion about utility-sponsored programs — confusion fraudsters exploit. See the Texas Solar Incentives Guide for what's actually available.
California: NEM 3.0's complexity (California's shift from retail-rate to reduced export rates in 2023) has created a new scam angle — installers pitching "grandfathered NEM 2.0" on new installs that legally can't get it. Any installer claiming you can get NEM 2.0 rates on a new 2026 install is lying. See the California Solar Incentives Guide.
South Carolina: The state's 25% solar income tax credit (up to $3,500/year) makes SC one of the most valuable incentive states in the Southeast — which also makes it a target for installers who claim larger credits than the statute allows or fail to disclose the annual cap. See the South Carolina Solar Guide.
Georgia: Door-to-door scammers frequently claim a "Georgia state solar credit" that does not exist (Georgia has no state income tax credit for solar). The framing closely mimics the federal ITC pitch to create confusion. See the Georgia Solar Incentives Guide.
The Pre-Sign Checklist: 5 Steps Before You Sign Anything
1. Get three quotes minimum. The How to Compare Solar Quotes guide walks through exactly what to standardize across competing bids. Prices from three NABCEP-affiliated installers give you market anchoring that exposes outlier pricing (too high = inflated; too low = corner-cutting).
2. Use the Solar System Designer to sanity-check the system size. Enter your annual kWh usage into the Solar System Designer — it will tell you approximately what system size you need. If an installer quotes you 2× the panel count the calculator recommends without explanation, ask them to justify it.
3. Read every line of the contract before signing. The How to Read a Solar Quote guide covers every section of a solar proposal — including the sections most buyers skip (production guarantee fine print, exclusion clauses, equipment substitution language).
4. Verify the installer's credentials using the 5-step process above. NABCEP lookup, state license check, BBB check, SEIA membership check, Google reviews audit — all take less than 10 minutes total.
5. Never sign under time pressure. "This price expires today" is a pressure tactic, not reality. Legitimate installers hold quotes open for 30 days because the equipment market is stable. Any "today only" deadline is a manipulation strategy. Sleep on it.
What Legitimate Solar Companies Will Always Do
To contrast with the fraud patterns above, here's what every reputable installer does as standard practice:
- Provides a written, itemized proposal with specific panel model, inverter brand, racking system, and production estimate methodology
- Pulls all permits and schedules inspections through the local building department
- Discloses all financing terms in writing — APR, dealer fees, escalator clauses, lease buyout schedule
- Offers a clear cancellation period (FTC requires 3 business days on in-home sales; reputable companies often extend this to 30 days)
- Has verifiable references from local customers whose installations were completed in the last 12 months
- Provides the equipment warranty documents at or before installation, not after you've paid
- Gives you utility interconnection documentation (PTO letter) when the system is legally commissioned

Frequently Asked Questions
Q: Is door-to-door solar sales itself a scam?
Door-to-door canvassing is a legitimate sales method used by many of the largest and most reputable installers (Sunrun, Freedom Forever, Palmetto Solar). The channel is not inherently fraudulent — but it is the primary delivery mechanism for most solar scams. The tactics used (fake deadlines, identity impersonation, high-pressure same-day signature demands) are the red flags, not the door knock itself.
Q: How do I know if a "government solar program" is real?
Legitimate government programs (USDA REAP, WAP, LIHEAP, Energy Community ITC) are applied for through licensed contractors, not announced by door-to-door reps. No government agency will appear at your door to inform you that you've been "selected" for free solar. When in doubt, call the named agency's public hotline directly using the number on their official .gov website.
Q: Can I cancel a solar contract after signing?
The FTC's "Cooling-Off Rule" gives you 3 business days to cancel any contract signed in your home or at a location that's not the seller's permanent place of business. Most states extend this to 5–10 days, and many reputable installers offer 30-day cancellation windows. Check your contract for the cancellation clause and your state's home solicitation law.
Q: What should I do if my installer won't return my calls after installation?
First, send a certified letter to the installer's registered business address documenting your issue and requesting a response within 10 business days. Simultaneously file a complaint with your state contractor licensing board and the BBB. If you made any payment by credit card, contact your issuer. Your state's AG consumer protection division can advise on contractor bond recovery options.
Bottom Line
Solar is one of the best investments most homeowners can make — but the combination of large dollar amounts, complex technology, and aggressive sales culture makes it a target for bad actors. The single best protection is patience: take your time, get three quotes from verified installers, read every word of your contract, and walk away from anyone who pressures you to sign today.
Use the Solar ROI Calculator to estimate your personal return before talking to any installer — knowing what a realistic payback looks like in your state makes it much harder for a scammer to inflate your expectations. Then use the How to Compare Solar Quotes guide and How to Save Money on Solar Installation to negotiate with confidence.
The best solar installers are eager to answer every question, provide references, and give you all the time you need. Any installer who makes you feel rushed, confused, or pressured is a company to avoid.
