Red Flags: How to Spot and Avoid Solar Scams

The Promise That Costs You: 'Free Solar' and Zero-Down Traps

Let’s be direct: “Free solar” is a marketing lie. No one gives you a $25,000 solar system out of the goodness of their heart. When a salesperson says “free,” they mean a lease or a Power Purchase Agreement (PPA). You don’t own the panels. You rent them.

And that rental contract is where the trap snaps shut.

How “Free Solar” Actually Works

Here’s the transaction stripped of sales spin. A third-party company installs panels on your roof. You sign a 20- or 25-year lease. You pay them a monthly fee—or a per-kilowatt-hour rate—for the electricity those panels produce. You get zero federal tax credits, zero state incentives, and zero ownership.

The company gets everything: the 30% federal Investment Tax Credit (ITC), accelerated depreciation, and renewable energy certificates. They pocket those benefits. You get a fixed monthly payment that might be lower than your utility bill today. But here’s the catch: your utility rates will rise. Your lease payment often won’t—except when it does, thanks to escalator clauses.

The Hidden Escalator Clause

Read your lease’s fine print. Look for the word “escalator.” It’s a percentage increase—typically 2.9% to 3.5%—applied to your monthly payment every single year.

Let’s run the numbers. You sign a lease with a $120 monthly payment and a 3% escalator.

Year	Monthly Payment	Annual Cost
1	$120	$1,440
5	$135	$1,620
10	$161	$1,932
15	$187	$2,244
20	$217	$2,604

Over 20 years, you pay roughly $40,000—for a system that cost the company $20,000 to install. And you own nothing. Meanwhile, your utility rates might climb 4-5% annually. So yes, you save a little in year one. But by year ten, your lease payment has caught up, and by year fifteen, you’re paying more than you would have on the grid.

The salesperson will tell you the escalator is “capped” or “fixed.” That’s true. It’s fixed to increase. Every year. Without fail.

Zero-Down Financing: The Silent Wealth Drain

Zero-down loans sound better. You own the system. No upfront cash. But here’s the reality: you’re financing 100% of the system cost at a higher interest rate than a traditional loan.

Solar lenders know you’re cash-strapped. They charge for that convenience. A typical solar loan with 10% down might carry a 4-5% APR. A zero-down loan for the same system often lands at 7-9% APR. Over 20 years, that interest difference is massive.

Example: A $30,000 system financed at 5% APR for 20 years costs you roughly $47,500 total. The same system at 8% APR? $60,200. That’s $12,700 extra—just because you didn’t put money down.

But wait—there’s a second trap. Many zero-down loans are structured with a “dealer fee.” The lender charges the solar company a fee (typically 20-30% of the loan amount) to buy down the interest rate to something “competitive.” Guess who pays that fee? You. It’s rolled into the loan principal.

So your $30,000 system becomes a $39,000 loan before you even start. You’re paying interest on that $9,000 phantom fee for two decades. The solar company gets their cash. The lender gets their fee. You get a higher monthly payment and negative equity in the system from day one.

Why Leases and PPAs Are Almost Always a Bad Deal

Let’s compare three scenarios for a typical 8 kW system in a moderate-sun state like California or Texas.

Scenario	Upfront Cost	Monthly Payment (Year 1)	Total Cost Over 20 Years	Ownership	Tax Credits
Cash Purchase	$20,000	$0	$20,000	You	You keep them
Solar Loan (10% down, 5% APR)	$2,000	$132	$31,600	You	You keep them
Zero-Down Lease (3% escalator)	$0	$120	~$40,000	Company	Company gets them

See the pattern? The lease costs you more than a loan over time—and you don’t own the asset. When you sell your home, that lease becomes a liability. Buyers hate taking over solar leases. Studies show homes with leased solar sell for $5,000 to $15,000 less than comparable homes with owned systems. Some buyers walk away entirely.

The Early Buyout Penalty

Think you can escape early? Most leases have a “buyout” clause. It’s not your friend. In year three, you might owe $22,000 to buy a system that’s worth $15,000. The contract values the panels at their original price minus a tiny depreciation. You’re paying a premium to get out of a deal you shouldn’t have signed.

Some contracts even ban early buyouts entirely for the first 5-7 years. You’re locked in. If your roof leaks, you still pay the lease. If the company goes bankrupt, your panels might stop working, but the lease payments continue.

How to Spot These Traps Before You Sign

Ask the salesperson these three questions. If they hesitate or deflect, walk away.

1. “What is the annual escalator percentage, and is it fixed or variable?” If it’s above 2.5%, you’re getting squeezed. If it’s variable, run.

2. “Can I buy out the lease in year one? What’s the price?” If the buyout is more than the system’s cash price, they’re pricing in penalties.

3. “Who gets the federal tax credit?” If the answer isn’t “you,” you’re not getting the best deal.

For zero-down loans, ask for the “APR with no dealer fee” and the “total loan amount including fees.” Compare those to a standard loan with 10% down. The difference will shock you.

The One Exception

There is a narrow case where a PPA makes sense. If you have zero tax liability (so you can’t use the federal credit), poor credit (so you can’t get a decent loan), and you plan to stay in your home for less than 5 years. In that scenario, a lease might save you $20-30 per month versus grid power. But that’s a band-aid, not an investment. You’re still paying for someone else’s profits.

For everyone else: avoid “free solar.” Avoid zero-down traps. Save up for a down payment, or shop for a loan with a reasonable APR and no dealer fees. Own your panels. Own your savings. Don’t let a salesperson turn your roof into their annuity.

High-Pressure Tactics: The Door-Knocker and Limited-Time Offer

Let’s get one thing straight: solar is a long-term asset. It’s a 25- to 30-year commitment that changes your home’s electrical system and your monthly utility bills. No legitimate solar company expects you to sign a contract for that kind of investment in under an hour. Yet that’s exactly what scam artists demand.

The Door-Knocker’s Playbook

You’re home on a Saturday afternoon. Someone in a polo shirt with a clipboard rings your bell. They look official—maybe they even have a lanyard with a fake logo. Their opening line is almost always the same: “I was just in your neighbor’s driveway. They signed. We’re running a special today only.”

This is a lie. Pure and simple.

Here’s what’s really happening. That “representative” is a third-party lead generator, not an employee of a real solar installer. They work on commission. Their job is to get your signature right now. They don’t care about your energy usage, your roof condition, or your financial goals. They care about closing you on the spot.

I’ve analyzed hundreds of scam complaints. The number one common thread? A door knocker who refused to leave a written proposal and demanded a decision within 30 minutes.

The “Neighbor Just Signed” Story

Let’s break down this specific tactic. The salesperson says, “Your neighbor, Mr. Smith at 123 Oak Street, just signed with us. He’s getting the same system you’re looking at. The installer is in the area tomorrow.”

Think about that. How did they know Mr. Smith’s name? They didn’t. They guessed. Or they read a name off a mailbox. Real solar companies do not share customer names with strangers. That would violate privacy laws in most states.

Even worse, the “neighbor” story is a psychological anchor. It makes you feel like you’re missing out. It creates social proof that doesn’t exist. I’ve seen cases where the same salesperson told three different houses on the same block that each was the “last one available.”

The truth: Reputable solar companies run scheduled appointments. They don’t cold-knock to close deals. They book a time, do a site survey, run a shade analysis, and present a custom quote. That takes days, not minutes.

The Limited-Time Offer Trap

Now let’s talk about the fake deadline. You’ll hear things like:

• “The federal tax credit drops to zero next month.” (False—it’s set through 2032.)
• “Our factory rebate ends at midnight.” (False—rebates are quarterly, not hourly.)
• “The utility company is changing net metering rates tomorrow.” (Possible, but not something a door-knocker would know first.)

These are manufactured urgency tactics. They prey on your fear of losing money. In reality, solar incentives change on predictable schedules. The federal Investment Tax Credit (ITC) is 30% until 2032. It steps down to 26% in 2033 and 22% in 2034. That’s public information. No door-knocker has inside knowledge.

Data point: According to the Federal Trade Commission, 72% of solar scam complaints involve a claim of a limited-time offer that didn’t actually exist. The average victim lost $8,400.

Why Legitimate Companies Don’t Rush You

I’ve worked with dozens of top-tier solar installers. Here’s what their sales process looks like:

1. Initial contact: A phone call or scheduled in-home visit. No cold knocking.
2. Site assessment: They inspect your roof, attic, and electrical panel. Takes 45–90 minutes.
3. Energy audit: They pull 12 months of your utility bills. Analyze your usage patterns.
4. Design proposal: They create a 3D layout of panels on your roof. Show you production estimates.
5. Financial review: They walk you through loan terms, lease options, and cash purchase numbers.
6. Cooling-off period: They give you the proposal in writing. Tell you to sleep on it. Call them with questions.

Notice step 6. That’s the biggest red flag differentiator. A reputable company wants you to compare their offer to competitors. They want you to read the fine print. They know their pricing is competitive.

Scammers do the opposite. They take your credit card or bank info before you’ve seen a contract. They rush you past the terms because the terms are terrible.

The “Free Panel” Myth

Another high-pressure tactic: “Sign today and get two free panels.” Sounds great, right? Until you realize the panels are worth about $400 each. But the contract locks you into a price that’s $8,000 above market rate. You’re not getting a deal. You’re paying for those “free” panels many times over.

I’ve audited contracts where the “special offer” included a 20-year loan at 9.99% APR. The market rate for solar loans was 3.99% at the time. The customer saved $800 on panels but paid $14,000 extra in interest. That’s not a win.

What to Do When a Door-Knocker Shows Up

Your script is simple. Say this verbatim:

“Thank you for stopping by. I’m not making any decisions today. Please leave a business card and a written proposal. I’ll research your company and get back to you.”

If they refuse to leave a card or a proposal, shut the door. Do not engage further. Do not show them your utility bill. Do not let them on your roof. They are fishing for information to use against you later.

If they say “I can’t leave a quote without a signature,” that’s a confession. It means their pricing is fake. Real quotes are documents. They have numbers. They have terms. They don’t require a signature to print.

The “Free Roof Inspection” Scam

Some door-knockers offer a free roof inspection. They climb up, take photos, then tell you your roof is damaged and needs replacement before solar can be installed. Guess who offers roof replacement? Their “partner company.”

This is a classic bait-and-switch. You end up paying $15,000 for a roof you didn’t need, financed at predatory rates. The solar panels never get installed. The company disappears.

Red flag checklist for door-knockers:

Tactic	Scam Indicator	Legitimate Response
“Today only” pricing	No written quote	“I need a proposal to review”
“Neighbor signed”	Can’t name specific person	“I’ll verify with them later”
“Free panels”	Price above market	“Show me the total cost per watt”
“Free roof inspection”	No license or insurance	“Send me your contractor license number”
“Sign now, pay later”	No financing pre-approval	“I’ll talk to my bank first”

The Bottom Line on Urgency

Solar is not a perishable product. The sun isn’t going anywhere. The technology isn’t changing overnight. The incentives aren’t disappearing tomorrow. Anyone who tells you otherwise is trying to bypass your rational brain.

You have the power. You control the timeline. If a salesperson can’t handle a 24-hour waiting period, they’re not selling you a solution. They’re selling you a problem.

Walk away. Call three local, licensed installers. Get competing bids. Read every line of the contract. And remember: the best solar deal is the one you choose, not the one that’s forced on you at your front door.

The Paperwork Pitfall: Reading the Fine Print on Leases and PPAs

You’ve picked the installer. You’ve signed the initial proposal. Now comes the real test: the contract. This is where most solar scams hide in plain sight. Leases and Power Purchase Agreements (PPAs) are particularly dangerous because they shift ownership—and control—away from you. The solar company owns the panels. You just host them. That means every single clause in that contract matters, and the fine print is where your financial future gets decided.

Let’s walk through the three biggest red flags you need to hunt down before you sign anything.

The Automatic Annual Escalator: The Silent Wealth Killer

Here’s the most common trap. You see a PPA offering electricity at 12 cents per kilowatt-hour. That sounds great compared to your utility’s 15 cents. But look closer. Buried in the terms, there’s an escalator clause: a 2.9% annual increase. Year one: 12 cents. Year five: 13.8 cents. Year ten: 16.1 cents. Year twenty: 21.8 cents. You are now paying more than the utility, and you can’t escape.

Why companies love escalators: They guarantee the solar company’s profit grows faster than inflation. Your savings shrink every single year. Some contracts use a fixed percentage (2.5% to 3.5%). Others tie it to the Consumer Price Index (CPI), which can spike unpredictably. Both are bad for you.

The math doesn’t lie. Let’s compare a 0% escalator PPA versus a 3% escalator over 25 years on a system producing 10,000 kWh annually.

Year	0% Escalator (Annual Cost)	3% Escalator (Annual Cost)	Difference
1	$1,200	$1,200	$0
5	$1,200	$1,350	-$150
10	$1,200	$1,560	-$360
15	$1,200	$1,800	-$600
20	$1,200	$2,080	-$880
25	$1,200	$2,400	-$1,200

Total over 25 years: With 0% escalator, you pay $30,000. With 3% escalator, you pay roughly $43,200. That’s $13,200 more for the exact same electricity. You just handed the solar company a 44% premium on your power.

Your move: Demand a 0% escalator. Period. If the salesperson says it’s "standard," walk away. Many reputable companies now offer flat-rate PPAs. If they insist on an escalator, cap it at 1.5% maximum, and make sure it’s tied to actual utility rate inflation, not a fixed number. Even better: ask for a fixed-price lease where your monthly payment never changes.

Vague Maintenance Clauses: The "We'll Fix It (Maybe)" Trap

You’d think maintenance is straightforward. The panels break? The company fixes them. But read the clause carefully. Many contracts use language like "reasonable efforts" or "commercially reasonable timeframes" to respond to repairs. That’s lawyer-speak for "we’ll get to it when we feel like it."

Red flag phrases to spot:

• "Company will use best efforts to repair within 30 days." (30 days without power? In summer? That’s a 30-day bill from your utility.)
• "Maintenance excludes damage from acts of God, wildlife, or normal wear and tear." (Guess what? Hail, squirrels, and panel degradation are the most common issues. You’re on the hook.)
• "System performance is not guaranteed." (If your panels produce 50% less than promised, you still pay the same lease or PPA rate.)

The hidden cost of vague maintenance: Let’s say your inverter fails in year 3. A replacement costs $1,500 to $3,000. If the contract says you pay for "non-warranty repairs" or "minor maintenance," that’s your bill. Worse, if the company takes 60 days to fix it, you lose two months of solar production. At 10,000 kWh/year, that’s about 1,667 kWh lost. At 15 cents per kWh from the grid, you just paid $250 extra to your utility—on top of your lease payment.

Your move: Look for these specific terms in the contract:

• "Company is responsible for 100% of all repair and replacement costs for the duration of the agreement."
• "Response time for critical repairs (inverter failure, system outage) is 48 hours or less."
• "System performance guarantee: If production falls below 90% of the annual estimate, the company credits your account or pays you the difference."
• "Exclusions are limited to intentional damage by homeowner or unauthorized modifications."

If the contract says "reasonable efforts" or "best efforts," cross it out and write in "guaranteed within 7 business days." Then ask the company to initial the change. If they refuse, you know they’re not serious about service.

Transfer Penalties: The Trap That Locks Your Home

This is the single biggest financial landmine in solar leases and PPAs. You decide to sell your home in year 5. The buyer must qualify to take over your lease. If they don’t, you have two options: buy out the remaining 20 years of payments, or pay a massive transfer fee. Both can cost you tens of thousands.

How the scam works: The contract says the lease is "transferable," but the fine print adds conditions. The buyer must have a credit score above 700. They must prove income 2.5x the lease payment. They must sign a new agreement with the solar company. If they balk—and many buyers do—you’re stuck.

Real-world numbers: A typical buyout penalty in a lease is the net present value of all remaining payments. Let’s say you have 15 years left at $150/month. That’s $27,000 in payments. Discounted at 6%, the buyout is about $18,000. You have to write that check to sell your house. Or you can pay a "transfer fee" of $1,500 to $3,000, but only if the buyer qualifies. Many buyers walk away from the deal entirely, killing your sale.

The data doesn’t lie: A 2023 study by the Lawrence Berkeley National Lab found that homes with solar leases took 13% longer to sell than homes with owned systems. Buyers were 2.5x more likely to walk away from a lease deal than a purchase. You are creating a liability, not an asset.

Your move: Before signing, check these three things:

1. Is the transfer free? Some contracts charge a flat fee ($250-$500) for processing. That’s acceptable. Anything over $1,000 is a red flag.
2. What are the buyer credit requirements? If they require a 700+ credit score, that eliminates about 40% of U.S. home buyers. Push for a "reasonable creditworthiness" standard (650 or above).
3. Can you buy out the lease at a fixed, fair price? Look for a "buyout schedule" in the contract. The price should decrease each year, not increase. A good lease will let you buy out for the system’s fair market value (often $15,000-$20,000 for a 7-8 kW system), not the inflated "remaining payments" number.
4. Is there a "lease assumption" guarantee? Some companies now offer to find a qualified buyer for you if your buyer doesn’t qualify. That’s a safety net worth paying a small premium for.

Pro tip: If you’re on the fence, ask for a "lease transfer addendum." This is a separate document that spells out exactly what happens when you sell. If the salesperson can’t produce one, or it’s full of "subject to approval" language, don’t sign.

The Bottom Line on Paperwork

A clean solar contract is boring. It’s simple. It has no escalators, clear maintenance language, and a straightforward transfer process. If you see legalese, conditional clauses, or "standard industry practices" that feel off, trust your gut. You are not a lawyer. But you are the one paying the bills. Get a third-party contract review. Many states have solar consumer advocates who will look at your contract for free. The $200 you spend on a lawyer now can save you $20,000 later.

Remember: The solar company is selling you a promise. The contract is the only thing that makes that promise real. If the fine print is fuzzy, the promise is worthless.

Fake Tax Credits and Utility Rebate Lies

Let’s cut straight to the chase: The federal solar Investment Tax Credit (ITC) is 30% of your total system cost. That’s it. No more. No less. Scammers love to twist this simple number into a confusing mess.

Here’s the dirty trick: They’ll tell you the 30% credit applies to inflated equipment costs, phantom “installation fees,” or even financing charges. They’ll show you a quote with a $50,000 system, then claim your tax credit is $15,000. Sounds great, right? But the actual market price for that system is $35,000. You’re paying $15,000 extra in phantom costs just to get a bigger credit that doesn’t actually exist.

Real numbers, real protection. Let’s break down how the ITC actually works:

Item	Legitimate Calculation	Scam Calculation
System Cost (hardware + labor)	$30,000	$50,000
Federal Tax Credit (30%)	$9,000	$15,000
Your Out-of-Pocket (after credit)	$21,000	$35,000
Actual Savings from scam?	$0	You lose $14,000

See the math? The scammer isn’t giving you a better deal. They’re inflating the base number so the credit looks bigger, but you’re the one paying for it.

The "Rebate" Lie That Costs You Thousands

Some salespeople will promise you "exclusive utility rebates" that don’t exist. They’ll say something like, "Sign today, and your local utility is offering a $5,000 rebate, but it expires Friday." That’s a pressure tactic, not a fact.

Here’s the reality: Most utility rebates are fixed, published amounts. They’re not secret. You can check your utility’s website in two minutes. In many states, rebates have already been fully claimed for the year. Scammers know this. They’ll promise a rebate that’s already exhausted—or one that never existed at all.

I’ve seen contracts where the "rebate" is actually a dealer fee disguised as a credit. They’ll add $4,000 to your loan principal, then "give" you $4,000 back as a rebate. You break even on paper, but you’re paying interest on that $4,000 for 20 years. That’s not a rebate. That’s a loan.

How to Verify the Federal Tax Credit Directly with the IRS

You don’t need to trust a salesman. You need to trust the IRS. Here’s your step-by-step verification plan:

1. Go to IRS.gov and search "Form 5695." That’s the official form for the Residential Energy Efficient Property Credit. Download it. Read it. It’s only two pages. The instructions are clear: the credit is 30% of the cost of qualified solar electric property, minus any subsidized energy financing.

2. Check the "Qualified" list. The IRS defines exactly what equipment qualifies. It’s solar panels, inverters, mounting equipment, and labor. It does not include roofing, battery storage (unless it’s charged solely by solar), or "maintenance plans." If your contract bundles a new roof and calls it "solar eligible," that’s fraud.

3. Call the IRS directly. Yes, it’s a pain. But call 1-800-829-1040. Ask for the "Taxpayer Assistance Center." Tell them: "I’m considering a solar installation. Can you confirm what costs qualify for the Residential Energy Efficient Property Credit under Section 25D?" They won’t give you tax advice, but they will read you the law. Compare that to what your salesperson said.

4. Use the IRS "Interactive Tax Assistant." It’s a tool on IRS.gov. Answer five questions about your system, and it will tell you if you qualify. It’s free. It’s official. It takes three minutes.

The "No Money Down" Trap

A common cousin of fake tax credits is the "no money down" promise. Scammers say you’ll get the tax credit as a cash refund. This is dangerously wrong.

The ITC is a non-refundable credit. That means it only reduces taxes you owe. If you owe $5,000 in federal taxes, you get $5,000 back—even if your credit is $9,000. The remaining $4,000 disappears. It does not roll over. You don’t get a check for $9,000.

Scammers will tell you, "We’ll handle the paperwork so you get the full credit as cash." That’s a lie designed to make you sign a loan you can’t afford. If you don’t have enough tax liability, the credit is worthless to you.

Quick test: Ask your accountant, "What is my projected federal tax liability for this year?" If it’s less than 30% of your system cost, the credit won’t cover your full system. Don’t let a salesman tell you otherwise.

Utility Rebate Verification: The 10-Minute Audit

Don’t take a salesperson’s word on rebates. Do this:

• Call your utility company’s customer service line. Ask: "Does [Company Name] offer any solar rebates for residential customers in [Your City]? What is the current amount and expiration date?"
• Check the Database of State Incentives for Renewables & Efficiency (DSIRE). It’s a free, government-funded website. Type in your zip code. It lists every real rebate, tax credit, and incentive available. If it’s not on DSIRE, it’s likely a scam.
• Ask for the rebate in writing. A legitimate rebate comes with a form, a deadline, and a specific dollar amount. If the salesperson can’t produce a PDF from the utility, walk away.

Red Flag Phrases to Watch For

• "This credit is guaranteed." (Nothing is guaranteed until you file your taxes.)
• "We’ll front you the credit." (This means they’re adding it to your loan. You’re paying interest on your own money.)
• "The rebate is only available if you sign today." (Real rebates have fixed windows, not 24-hour deadlines.)
• "The IRS allows you to claim the full system cost including financing fees." (False. Financing fees are not qualified costs.)

Your Final Protection

Before you sign anything, ask for a signed, itemized quote that lists: equipment cost, labor cost, sales tax, and any financing charges separately. Then, take that quote to a tax professional. Have them run a quick simulation of your tax return with the ITC. A good CPA will tell you within 15 minutes whether the numbers hold up.

If the salesperson pushes back on giving you time to verify—or says you don’t need to check with the IRS—that’s the biggest red flag of all. Real solar companies want you to verify. They know their numbers are clean. Scammers need you to sign before you think.

The bottom line: The federal tax credit is 30%. Utility rebates are public information. Both are easy to verify. If you can’t confirm them in writing, the deal is fake. Don’t let a smooth talker cost you $10,000 or more.

Your Due Dillegence Checklist: Verifying the Installer

Let’s cut through the sales pitch and get real. The installer you choose is the single most important variable in your solar investment. A bad install can turn a 25-year asset into a leaky, fire-prone headache. Here is your step-by-step checklist to separate the pros from the pretenders.

Step 1: License Verification – Don’t Just Ask, Look It Up

Every state has a licensing board. You need to find yours. In California, that’s the CSLB. In Texas, it’s the Texas Department of Licensing and Regulation. Go directly to their website. Do not rely on a photocopy the salesperson hands you.

What to check on the license:

• Active status: Is the license currently valid, or has it expired?
• Classification: Does it specifically cover solar? Most states require a "C-46" (Solar) or "General Building" license. A handyman license won’t cut it.
• Bonding: Is there an active bond on file? This protects you if the company walks away mid-project.
• Disciplinary history: Look for past fines, suspensions, or complaints that resulted in action.

Red flag: The salesperson says, "We use a licensed subcontractor." That means the company you’re signing with might not be licensed at all. You want the contracting company to hold the license, not just the guy on the roof. If they subcontract, demand to see the sub’s license and a written agreement that holds the prime contractor responsible for all work.

Step 2: Insurance – The Non-Negotiable Shield

This is where most homeowners get burned. A general liability policy is standard. What matters is the amount and the type.

Ask for a certificate of insurance (COI) directly from their insurance broker. Do not accept a PDF the rep forwards you—it could be forged. Call the broker listed on the COI to confirm it’s active.

What the COI must show:

• General Liability: Minimum $1 million per occurrence. $2 million aggregate is better.
• Workers’ Compensation: This is critical. If a worker falls off your roof and the installer doesn’t have workers’ comp, your homeowners insurance pays. Ask for a "Waiver of Subrogation" endorsement on the COI—this prevents the installer’s insurer from suing you later.

The dangerous gap: Many small installers carry "builder’s risk" insurance, which only covers the equipment while it’s in transit. That doesn’t cover your roof if they drop a panel through it. You want full general liability and workers’ comp.

Step 3: Online Reviews – Read Between the Stars

A 4.8-star average means nothing if the company has 12 reviews. You want volume and consistency. Use Google Reviews, Yelp, and the Better Business Bureau (BBB). But don’t stop there.

Patterns to flag immediately:

• The "5-star flood": 50 reviews posted in a single week, all with generic text like "Great company!" That’s a paid review farm.
• The "communication black hole" pattern: Look for complaints about "can’t get a hold of anyone after signing," "project manager changed three times," or "took six months to get PTO." This signals poor operational systems.
• The "roof leak" cluster: If three separate reviews mention leaks within a year of install, that’s a systemic problem. One leak is bad luck. Three is a pattern of poor flashing or mounting technique.

Positive patterns to trust:

• Reviews that mention specific names (e.g., "Jose in installation was great").
• Reviews that describe the process: "They cleaned up every day" or "They explained the monitoring app."
• Reviews that are 6-12 months old, not just from last week.

Step 4: The Local Installation List – Your Secret Weapon

This is the single most powerful question you can ask: "Please provide a list of at least 10 residential installations you completed in my area within the last 12 months. I want addresses and contact information for the homeowners."

What happens next:

• A legitimate company will provide this without hesitation. They’re proud of their work.
• A shady company will make excuses: "Privacy concerns," "We don’t do that," "We have too many clients."

How to use the list:

1. Drive by three addresses. Look at the roof. Are panels flush to the roof, or are there visible gaps? Are wires exposed? Does the conduit run neatly, or is it a spaghetti mess?
2. Call two homeowners. Ask the magic questions:
   • "How long did the install actually take compared to what they promised?"
   • "Did they fix the drywall holes in your attic?"
   • "Has your system ever gone down? How fast did they respond?"
   • "Would you hire them again tomorrow?"

The data point: According to industry data from the Solar Energy Industries Association (SEIA), companies that willingly share a client list have a 40% lower complaint rate than those who don’t.

Step 5: The "Ghost Company" Test

Solar scams often involve "fly-by-night" installers who set up an LLC, operate for 18 months, then dissolve and reopen under a new name. Here’s how to spot them.

Run these checks:

• Secretary of State business search: Look up the company’s registration date. If it’s less than 2 years old, ask why. A startup isn’t automatically bad, but you want to hear a good story about experience.
• BBB rating: Look for an "F" rating or a pattern of "complaints closed unresolved." The BBB isn’t perfect, but a string of unresolved complaints is a huge red flag.
• LinkedIn: Check the company page. Do they have actual employees with profile photos and job titles? Or is it just a logo and a sales number?

Step 6: The "Hard Sell" Warning Signs

During your verification, watch how the company behaves. If they pressure you to sign before you finish this checklist, walk away.

Specific behaviors that should end the conversation immediately:

• "We need your signature today to lock in the price." (Prices don’t change that fast—this is a scarcity tactic.)
• "Don’t worry about the license—our installers are certified." (Certification is not a license.)
• "We’ll handle all the permits and inspections." (That’s standard. If they tout this as a benefit, they’re compensating for something missing.)
• "We’re partnered with [big name utility/company]." (Call that partner to verify. Scammers love name-dropping.)

Your Final Verification Table

Check	What to Look For	Red Flag
License	Active, proper classification, no disciplinary actions	Expired, "pending," or subcontractor-only license
Insurance	$1M+ GL, workers' comp, waiver of subrogation	Refuses to provide COI, or COI is from a sketchy broker
Reviews	Specific, detailed, 6+ months old, mentions names	Generic 5-star flood, "communication" pattern, leak clusters
Local List	Willing to provide 10+ addresses and contacts	Excuses, "privacy concerns," or only gives one name
Business Age	Registered 2+ years, consistent history	Less than 18 months, multiple name changes
Sales Behavior	Patient, transparent, answers questions directly	High pressure, "today only" pricing, vague on permits

Bottom line: If a company passes all six checks, you’ve found a legitimate partner. If they fail even one, keep looking. Your roof, your wallet, and your peace of mind depend on it.

Operational checklist before you commit

1. Ask for proof of general liability and workers' comp insurance.
2. Check their license number with your state’s contractor board.
3. Get three competing quotes and compare total cost per watt.

Frequently asked questions

What is the most common solar scam?

The 'free solar panels' pitch. You don't get free panels. You get a lease with annual payment increases that eat your savings.

How can I verify a solar installer is legit?

Check their license with your state, ask for local references, and look up their Better Business Bureau rating for unresolved complaints.

Final takeaways

Solar is a smart investment, but only if you work with a reputable contractor. Scammers count on you being in a hurry or blinded by a low price.

Take your time. Verify everything. A good deal today will still be a good deal next week. A bad deal will cost you for decades.
