Solar Loan Dealer Fee Lawsuit: The Hidden Fee That Inflated Your Loan — and How to Fight Back
If you financed rooftop solar and later realized your loan balance was thousands of dollars higher than the system’s actual price, you were probably charged a hidden “dealer fee.” It is the single most common — and most heavily litigated — problem in residential solar financing. A solar loan dealer fee lawsuit typically alleges that a lender concealed this fee, folded it into the loan principal, and quietly charged interest on it for 20 to 25 years. State attorneys general have sued the largest solar lenders in the country over exactly this practice, and thousands of homeowners are now pursuing individual claims.
This guide is written for the homeowner trying to answer one urgent question: was I overcharged, and can I do anything about it? Below, we explain how hidden solar dealer fees work, how large they really are, why they may be illegal, which lenders have been sued, how to check your own loan in minutes, and the exact steps to dispute or recover the fee. Credible Law is a national legal resource and attorney referral network — not a law firm — and connects homeowners with attorneys who handle solar contract disputes nationwide.
What Is a Solar Dealer Fee?
A dealer fee — sometimes called a platform fee, financing fee, or lender fee — is an upfront charge a solar lender collects in exchange for offering a low advertised interest rate. Rather than billing you for it separately, the lender adds the fee directly into your loan principal. The result is that you do not just pay the fee once; you pay interest on it for the entire life of the loan.
Here is the mechanic that catches most homeowners off guard. The eye-catching “0.99%” or “1.99%” APR that made the deal look irresistible is effectively bought and paid for by the dealer fee. The lender trades you a lower interest rate in exchange for a larger balance. Your monthly payment lands right where the salesperson promised — which is precisely why the fee goes unnoticed — but the amount you actually financed is far higher than the price you were quoted for the panels themselves.
The “0.99% APR” Trap, Explained
Think of it as a seesaw. On one side sits the interest rate; on the other sits the loan balance. To advertise a near-zero rate, the lender has to push the balance up — and the dealer fee is how it does that. A homeowner comparing a “1.99% solar loan” against a “7% home-equity loan” may believe solar is the obvious bargain, when in reality the 1.99% loan carries a 20% hidden fee that more than erases the rate advantage. The advertised rate is real; it is just not the whole story.
A Concrete Example
Suppose your installer quotes a $25,000 system and you finance it through a major lender at a typical dealer fee of roughly 19%. Your actual loan principal is closer to $30,750 — nearly $5,750 you never knowingly agreed to, now accruing interest for 25 years. Most homeowners believe the financed figure is simply the cost of parts, labor, and installation. Very often, it is not. And because the fee is baked into the balance rather than itemized, you can review your paperwork a dozen times and never see it spelled out as a fee at all.
How Big Are Hidden Solar Dealer Fees, Really?
The scale is documented — not by advocates, but by official investigations. When the Minnesota Attorney General sued four major solar lenders — GoodLeap, Sunlight Financial, Solar Mosaic, and Dividend Solar Finance — the complaint alleged the hidden fees increased borrowers’ costs by 15% to 30%, totaling roughly $35 million across more than 5,000 Minnesota solar installations between 2017 and 2023. Court filings cited in that litigation put one lender’s average dealer fee at about 19.3% of the loan — roughly $7,552 added to the typical borrower’s balance, money the homeowner was never told existed.
The federal Consumer Financial Protection Bureau has logged complaints echoing the same pattern — including one homeowner who reported being told that using a lender’s financing required adding 26% of the total system cost as an upfront fee the lender kept. Industry insiders have described dealer fees ranging from 10% to 30% of the loan, and in some documented cases higher than 50%. Stretched across a 25-year term, a $5,000 hidden fee does not stay $5,000; with interest, it can cost a homeowner many times that amount over the life of the loan.
To put the compounding in perspective: a $6,000 dealer fee financed at a modest rate over 25 years can add well over $10,000 to what you ultimately repay, once interest on the inflated principal is counted. That is the difference between the fee as a sticker number and the fee as a lifetime cost — and it is why even a “small” percentage matters so much on a long solar loan.
Why a Hidden Solar Dealer Fee May Be Illegal
A dealer fee is not automatically unlawful — fees exist across many financed products. The legal problem is concealment and disclosure. Several theories anchor the current wave of solar dealer fee lawsuits:
Truth in Lending Act (TILA): APR Disclosure Failures
The federal Truth in Lending Act requires lenders to disclose the true annual percentage rate before you sign, and that APR must reflect the real cost of credit — including fees. Plaintiffs allege that solar lenders displayed a low interest rate while failing to properly fold the dealer fee into the APR calculation, making the stated APR appear lower than the true cost of borrowing. If your disclosures advertised an attractive rate but buried a five-figure fee, that is exactly the kind of TILA problem attorneys examine — and on a home-secured loan, a TILA disclosure failure can support rescission rights extending up to three years.
State Deceptive-Practices (UDAP) Laws
Every state has an unfair-and-deceptive-acts-and-practices statute, and they target the core allegation head-on: that lenders told consumers the financed price reflected only equipment and installation, while concealing a costly upfront charge. Regulators allege most customers were never told they could pay the installer directly in cash to avoid the fee, or arrange their own financing without it. Depending on the state, these statutes can allow recovery of the fee, statutory damages, and attorney’s fees.
Improper, Altered, or Forged Documentation
In some cases, homeowners allege they were never shown the fee-inclusive loan documents at all, and a subset of complaints against major lenders involve allegations of forged or altered signatures on financing paperwork. Where that occurred, it opens claims well beyond disclosure — going to whether the loan was validly formed in the first place.
The Lender May Be on the Hook — Even If the Installer Vanished
Many homeowners assume that if the company that sold and installed their panels has gone bankrupt, they are stuck. The FTC Holder Rule can change that. It allows a borrower to raise the seller’s misconduct against the lender who financed the deal — meaning the finance company holding your loan may be accountable for how the fee was presented, even if the installer is long gone.
Which Solar Lenders Have Been Sued Over Dealer Fees?
Several of the largest names in residential solar financing have faced dealer-fee allegations. The following reflects public regulatory actions and litigation; these are allegations that are being contested, and none of it establishes that any company has been found liable.
GoodLeap
One of the largest residential solar lenders in the country, GoodLeap was a named defendant in the Minnesota action. Figures cited in that litigation put its average dealer fee near 19.3% per loan. GoodLeap has also been the subject of individual consumer complaints and at least one class action touching on hidden fees and loan documentation. The company has stated it will demonstrate its disclosures were compliant.
Sunlight Financial
Also named in the Minnesota suit, Sunlight Financial is alleged to have followed the same low-rate, hidden-fee model. The company later filed for bankruptcy — a reminder that a lender’s financial trouble does not erase a borrower’s potential claim, which may proceed through the bankruptcy’s claims process or against successors.
Solar Mosaic
Another national solar lender named in the Minnesota case, Mosaic has faced significant consumer-complaint volume and entered bankruptcy, with its large loan portfolio transferring to a successor servicer. Homeowners with Mosaic loans and a suspected hidden fee should preserve their documents while any successor-servicing questions are sorted out.
Dividend Solar Finance
The fourth lender named in the Minnesota action, Dividend is alleged to have used the same dealer-fee structure. As with the others, the central allegation is concealment — charging an upfront fee folded into the financed total without clear disclosure.
If your loan is with one of these lenders and your balance runs well above the system price you were quoted, a document review can tell you whether your specific loan shows the hallmarks at issue. Because these are complex, company-specific cases, it helps to work with an attorney who understands both the solar contract dispute landscape and the financing side.
How to Tell If You Were Charged a Hidden Dealer Fee
You can often spot the fee yourself in a few minutes with your paperwork in hand. Look for these signs:
- Compare two numbers. Put the cash price your installer quoted for the system next to the principal amount on your loan agreement. A gap of 10–30% with no line-item explanation is the classic signature of a dealer fee.
- Watch for a suspiciously low APR (0.99%–2.99%) paired with a balance well above the quoted system price. That trade-off is how dealer fees are funded.
- Ask whether a cash price was ever offered. If no one told you that paying the installer directly would avoid a financing fee, that omission is part of what regulators are challenging.
- Hunt for the fee in the disclosures. If the dealer fee is not clearly itemized — appearing only inside the total — note that; concealment is the heart of the legal claim.
- Check the signatures and figures. Confirm the numbers on your signed documents match what you were shown, and that the signatures are genuinely yours.
What You Can Do About a Solar Dealer Fee
Depending on your loan, your state, and the disclosures you received, attorneys pursue several outcomes in solar dealer fee lawsuits:
- Loan reduction — the financed balance is reduced to strip out the improperly disclosed fee, sometimes with interest recalculated on the corrected principal.
- Loan cancellation or rescission — where TILA disclosure failures on a home-secured loan are clear, rescission rights can reach up to three years, potentially unwinding the loan.
- Refunds and damages — state UDAP statutes may allow recovery of the fee itself plus, in some states, statutory damages and attorney’s fees.
- Individual arbitration — most solar loans force disputes into arbitration; for a five-figure hidden fee, an individual claim can recover more than a class settlement. Firms are already taking these fees to arbitration in volume.
One firm caution worth repeating: do not simply stop paying your loan because you suspect a hidden fee. Missing payments can trigger default and damage your credit before your claim is ever resolved. Any decision about payment should be made with a qualified attorney who has reviewed your documents. It is the same discipline attorneys apply when challenging an inflated or overstated balance in a merchant cash advance settlement: you attack the number through the correct process, not by walking away from the obligation and handing the lender the upper hand.
Solar Dealer Fees vs. Other Predatory Financing
The hidden solar dealer fee is not a one-off; it belongs to a broader family of financing practices where the real cost of a deal is obscured behind an attractive headline number. Small business owners see the same pattern in high-cost commercial financing, where a merchant cash advance can carry an effective cost far above what the paperwork suggests, and where challenging an inflated or overstated balance is central to the defense. The legal through-line is the same in both worlds: when a financing arrangement is built on concealed costs or missing disclosures, the law provides tools to challenge it. That is why attorneys who handle predatory-financing disputes are often well positioned to evaluate a solar dealer fee claim.
What to Do Right Now
Whether or not you ultimately file a claim, these steps protect your position:
1. Gather your documents. Your signed contract, the loan agreement and all disclosures, and any quote or savings sheet you were shown before signing.
2. Do the two-number comparison. Quoted cash price vs. financed principal. Write down the gap.
3. Identify your lender by name. GoodLeap, Sunlight, Mosaic, Dividend, or another — it determines which cases and claims may apply.
4. File a complaint with your state attorney general and the CFPB. Both are free, require no lawyer, and build the public record.
5. Talk to an attorney before changing your payments or signing anything the lender offers. Sequencing protects your credit and your leverage.
Frequently Asked Questions
Are solar dealer fees legal?
A dealer fee is not automatically illegal, but concealing it can be. The lawsuits focus on disclosure: whether the fee was hidden, whether it was properly reflected in the APR under the Truth in Lending Act, and whether consumers were told the financed price included a large upfront charge. Where the fee was buried, the conduct may violate federal and state law.
How do I know if I was charged a hidden solar dealer fee?
Compare the cash price your installer quoted to the principal on your loan. A gap of roughly 10 to 30% with no clear line item, especially paired with an unusually low APR, is the typical sign. If you were never offered a cash price to avoid a financing fee, that is a red flag regulators have highlighted.
How much are solar dealer fees?
Investigations have put them commonly in the 10% to 30% range, with one lender’s average cited at about 19.3% of the loan, and some documented cases higher than 50%. On a long solar loan, even a mid-range fee can add many thousands of dollars in interest over time.
Can I get a solar dealer fee refunded or removed?
Sometimes. Depending on the disclosures and your state, attorneys pursue loan reduction, refunds, rescission of the loan under TILA, or damages under state consumer-protection law. The outcome depends on your documents and how the fee was presented.
What lenders have been sued over solar dealer fees?
The Minnesota Attorney General sued GoodLeap, Sunlight Financial, Solar Mosaic, and Dividend Solar Finance over allegedly hidden dealer fees. Several are among the largest residential solar lenders in the country. These are allegations, and each case is being litigated.
What if my solar lender went bankrupt?
You may still have recourse. Claims can proceed through the bankruptcy’s claims process or against a successor servicer, and the FTC Holder Rule may let you raise the seller’s conduct against the finance company holding your loan. Preserve your documents and act promptly.
Should I stop paying my solar loan if it has a hidden fee?
No, not without legal advice. Stopping payment can trigger default and harm your credit before your claim is resolved. Speak with a qualified attorney about the right sequence before changing anything about your payments.
Is it worth pursuing a claim for a few thousand dollars?
Often, yes. Over a 20 to 25 year loan, a several-thousand-dollar hidden fee compounds into far more in interest, and state consumer statutes may add damages and attorney’s fees. Because most solar loans require individual arbitration, a single well-documented claim can be efficient to pursue.
How do I get rid of a solar dealer fee on an existing loan?
There is no self-service button, but the paths attorneys use include negotiating a reduced payoff, pursuing a refund or damages under state law, or seeking rescission where TILA disclosures failed. The right route depends on your documents, your lender, and your state, which is why a document review is the sensible first step.
