What to Do When a Solar Salesperson Lies About Savings + Other Common Misrepresentations

For many homeowners, the first sign that something is wrong with their solar installation shows up months later, long after the panels are on the roof and the salesperson is nowhere to be found. 

That’s exactly what happened to one homeowner, David, who was promised that his solar system would wipe out nearly all of his electricity costs with 99% savings. Instead, his system produced only 65% of what was promised, leaving him with a large electric bill and a long-term solar loan.

The gap between the promise and reality was so substantial that an arbitrator agreed the numbers were misleading. In his case, the misrepresentations were clear enough that he received a $24,000 reduction on an $82,000 loan, plus $3,800 in damages and an additional $1,500 award.

David’s experience reflects what we see every day: homeowners pushed into solar agreements based on inflated projections, false guarantees, or outright lies. These aren’t harmless exaggerations, they’re material misrepresentations that leave people paying for systems that don’t perform as sold.

This guide breaks down the most common types of solar sales lies, how to identify them, and what steps homeowners should take if they believe they were misled.

The Most Common Types of Solar Sales Lies

Solar misrepresentation usually falls into a handful of predictable categories. Understanding which one happened to you helps determine what protections apply and what your next steps should be.

1. Lies About Savings or Bill Reduction

This is the most common form of solar deception.

Sales reps may use common lies about savings such as:

• “You’ll save 70–100% on your electric bill.”
• “Your system will wipe out your utility bill completely.”
• “Your savings will be higher than your loan payment.”
• “Your bill will never go up again.”

In reality, many systems produce far less than promised. Some homeowners still pay full electric bills plus a solar loan.

This is a material misrepresentation because savings projections are a core part of the purchase decision.

2. Lies About System Performance or Production

Reps often exaggerate system output with tactics including:

• Using inflated offset percentages
• Miscalculating energy usage
• Comparing your system to ideal conditions that don’t exist on your roof
• Using faulty assumptions about shading, roof pitch, orientation, or local weather patterns
• Claiming the system would produce more power than physically possible

If the salesperson knew or should have known their numbers were unrealistic, this becomes a deceptive practice.

3. Lies About Warranties

Many homeowners are explicitly told:

• “You have a 25-year bumper-to-bumper warranty.”
• “Everything is covered—panels, labor, roof penetrations, inverter—you’re protected.”
• “If anything breaks, you’ll never pay out of pocket.”

But often what happens is:

• The warranty only covers equipment, not labor
• Roof penetration or workmanship issues aren’t included
• The installer goes out of business, then voiding their workmanship warranty
• The manufacturer won’t honor claims due to improper installation

When warranty claims don’t match what you were sold, that’s another form of misrepresentation.

4. Lies About System Approval (PTO)

A common scheme, for example, looks like this:

• Salesperson promises installation in 30–60 days
• Says PTO (Permission to Operate) is guaranteed
• Claims the system will be live “right away”

But for many homeowners what actually happens is:

• PTO never arrives
• The system sits on the roof producing nothing
• The utility never approved the design
• Missing paperwork or code violations block activation
• Homeowners make loan payments for a non-operational system

A system not approved by your utility is essentially worthless until PTO is granted.

5. Lies About Loans and Financing Terms

These are some of the most harmful lies because they create long-term financial damage.

Common examples we run across sound like:

• “Your payment will be cheaper than your power bill.”
• “Your rate will never go up.”
• “This loan is tax-deductible.”
• “You’ll get a tax credit big enough to cover your dealer fee or loan re-amortization.”
• “You’re getting a rebate” (when it’s really an added loan amount)
• Hiding the dealer fee, which can be $10,000–$30,000
• Misrepresenting payment escalators
• Not disclosing that the solar loan creates a UCC lien on your home

These lies can drastically affect a homeowner’s budget and financial health.

6. Lies About Your Roof or Home Compatibility

Some installers will say anything to get the sale, including:

• “Your roof can handle the system without upgrades.”
• “Your electrical panel doesn’t need updating.”
• “Your home is a perfect fit for rooftop solar.”

In many cases, the home actually required:

• A new roof
• Structural reinforcements
• Panel upgrades
• Home rewiring
• Additional equipment not disclosed

When those needs are ignored, homeowners end up with leaks, structural damage, or major unexpected costs.

7. Lies About the Tax Credit and How it Works

One of the biggest, and most financially damaging, misrepresentations in solar sales involves the federal tax credit. Many homeowners are promised huge tax credits that will “cover the dealer fee,” “drop your monthly payment,” or “give you thousands back at tax time.”

In reality, these claims are often completely false.

Here’s what really happens:

Homeowners promised large tax credits never received.

Sales reps regularly tell people they’ll get a credit worth 30% of the system cost…even when the homeowner is retired, on disability, or has very low taxable income. But the tax credit is not a rebate. You only get the amount you owe in taxes. If your income is low, you cannot receive a large credit. As a result, many homeowners qualify for only a fraction of what was promised…or nothing at all.

These inflated tax credits are used to qualify homeowners for lower monthly payments.

Solar loans often assume you will apply a large tax credit to the loan within 18 months. This temporarily lowers your payment. But if you never receive that credit—because you were never eligible—you’re stuck with a dramatically higher payment later.

Most homeowners don’t qualify anywhere near the amount they were told.

We regularly see cases where homeowners were promised $10,000–$25,000 in credits but only qualify for a few hundred dollars. The gap directly affects their actual cost and the long-term loan structure.

Even when homeowners do qualify, they may only receive the credit over several years.

If your tax liability is small, you can only claim a portion each year. And most solar loans require you to pay down the tax-credit portion within 18 months. If you can’t, even if you eventually qualify for the full credit over time, you still do not get the benefit of the reduced loan payment the salesperson promised.

This creates a financial trap.

Homeowners end up with higher payments, no tax credit to offset them, and a loan that was sold on false assumptions. Misrepresenting how the tax credit works is one of the clearest forms of deceptive sales practice in the solar industry.

Strange and Unethical Tactics Some Salespeople Use to Close a Deal

While most solar misrepresentations involve numbers, projections, or financing, some of the stories we hear from homeowners are so outrageous that they reveal just how far certain salespeople will go to make a sale. These tactics aren’t just unethical—they often create major legal and financial complications for the homeowner.

Here are some of the more extreme examples we’ve encountered:

A salesperson offered a client an AK-47 as an incentive to sign the contract.

Yes, this really happened. And no…this is not legal, ethical, or remotely normal.

A homeowner didn’t qualify for financing, so the salesperson brought in a friend to co-sign the loan.

This “creative solution” leaves the homeowner with a system they didn’t qualify for, and leaves both parties exposed. If a legal dispute arises, the co-signer—often a complete stranger—is suddenly a key figure in the case.

When the system failed, a salesman installed a second system and promised the loan would be canceled.

To “help,” he personally made the loan payments for 18 months via CashApp, then disappeared—leaving the homeowner with two active loans and no functional system.

Another homeowner was told to transfer the deed of their home to a friend to qualify for financing.

Because the loan must be in the homeowner’s name, they were pressured into temporarily signing over their deed so the friend could take out the loan. This is extraordinarily risky and can jeopardize property ownership.

We’ve even seen sales teams share stories internally about using extreme or questionable tactics to close deals.

In some sales channels, these behaviors are openly discussed or even celebrated—reinforcing an environment where homeowners become targets rather than clients.

What You Should Do If You Believe You Were Lied To

If any of the above sounds familiar, you do not have to just accept the situation. Here’s a practical step-by-step process for homeowners.

1. Gather Your Paperwork

Collect important documentation, such as:

• Contract
• Proposal
• Savings projections
• Production estimates
• Any text messages from the salesperson
• Emails or brochures
• Photos of the system
• Electric bills before and after installation

Misrepresentation is often proven with the installer’s own documents.

2. Compare Promised vs. Actual Savings or Output

Check important metrics about your system, like:

• Your contract’s projected annual output
• What your system is actually producing
• Whether your electric bill decreased as promised
• Whether your loan payment exceeds your savings

Even a 20–30% shortfall can support a misrepresentation claim.

3. Document All Problems

Make a list of:

• Underproduction
• False promises
• Missing equipment
• PTO delays
• System downtime
• Roof or property damage
• Warranty denials
• Utility issues
• Missing responses from the installer

This helps determine which category of misrepresentation ultimately applies.

4. Stop Relying on the Installer for Help

Most homeowners wait months—or years—hoping the installer will “make it right.” If you were lied to, they are unlikely to fix the core problem.

5. Get a Professional Legal Review

Solar contracts are dense, technical, and specifically written to protect the installer…not the homeowner.

A legal review can help you understand the details of your situation, including:

• Whether the misrepresentation qualifies as deceptive
• Whether warranties were breached
• Your options for financial relief
• How to protect your home and credit
• What next steps make the most sense for your case

And at Prevost, you can start with a No-Cost Case Review.

Final Thoughts: You Don’t Have to Accept False Promises

Solar can be a great investment—but only when the system performs as promised. If your savings aren’t close to what you were told, or if your sales rep used high-pressure tactics or unrealistic numbers, you have options.

A misleading proposal is not just “marketing.”
A false promise is not just “optimism.”
And a solar loan you were tricked into is not something you must be stuck with.

Homeowners deserve transparency, honesty, and systems that work the way they were sold. If that didn’t happen, you may have legal protections available.
