Uncovers hidden dealer fees in solar loans that inflate the principal by 25-31%, and teaches consumers how to demand an itemized breakdown.
Dealer Fees Exposed: How Solar Lenders Use 'Low APR' Offers and How to Get a Clear Loan Breakdown

Overview
The salesperson tells you the solar loan is 3.99% APR — an interest rate lower than your credit cards, lower than most car loans, and competitive with a home equity line. What they do not tell you: that 3.99% rate was bought. Behind it sits a dealer fee — a one-time origination charge paid by the installer to the lender — that inflates your loan principal by 25% to 31%. You are effectively paying thousands of dollars in points upfront, buried inside the loan balance, while being marketed a "low APR." This article exposes how dealer fees work, where they hide, and how to demand the transparency the law requires.
How Dealer Fees Work
Solar lenders — including GoodLeap, Mosaic, Sunlight Financial, and Dividend Finance — offer installers a menu of interest rates. Lower rates cost more: the installer pays a dealer fee to the lender, expressed as a percentage of the loan amount, to buy down the APR. The installer then passes this cost to you by inflating the total system price or the "amount financed."
The math is stark. A $30,000 solar system financed with a 3.99% APR might carry a 25% dealer fee. That is $7,500 added to your principal — a $37,500 loan for a $30,000 system. At 0.99% APR, the dealer fee can hit 31% — transforming a $30,000 system into a $39,300 loan. The borrower sees a great rate and never realizes they are financing the fee that created it.
The fee is not disclosed as a line item on most loan documents. It is baked into the principal. You borrow more, pay interest on the fee, and — if you sell the house — must pay off a loan balance inflated by thousands of dollars in charges you never knowingly agreed to pay.
What TILA Requires
The Truth in Lending Act requires lenders to disclose the finance charge, the amount financed, and the APR — all calculated in a specific, standardized manner. But here is the catch: TILA treats dealer fees as prepaid finance charges included in the finance charge calculation, not as a separate broken-out line item. The borrower sees a "Total of Payments" figure that may seem high relative to the system cost, but the specific dealer fee amount is not isolated.
This does not mean TILA authorizes hidden fees. It means that TILA's disclosure format — while providing important information — does not by itself expose the dealer fee structure. You must ask for the breakdown separately.
California SB 784: Mandatory Dealer Fee Disclosure
California has gone further than federal law. SB 784, effective in 2024, explicitly requires solar salespersons to disclose dealer fees — in writing, before the contract is signed. The disclosure must include the fee as both a dollar amount and a percentage of the system cost. Failure to comply is a statutory violation.
The Minnesota AG Investigation
In 2024, the Minnesota Attorney General's office opened an investigation into solar lenders, alleging that approximately $35 million in dealer fees had been hidden from Minnesota consumers. The investigation highlighted a systemic issue: consumers were being told they were getting a "low interest loan" when, in economic substance, they were paying substantial upfront charges that were never independently disclosed.
This investigation — and similar scrutiny from other state regulators — signals that dealer fee opacity is a recognized consumer protection problem. It is not merely a sharp business practice; in some cases, it may constitute deception.
How to Demand an Itemized Breakdown
Before signing any solar loan, send a written request for:
- The base system price (equipment plus installation, before any financing charges)
- The dealer fee — as a dollar amount and percentage
- The total amount financed and how it reconciles with the base system price plus dealer fee
- The APR and total of payments over the full loan term
- Any other fees, points, or charges included in the loan
Request this breakdown in writing. If the salesperson or lender cannot — or will not — provide it, treat that refusal as a red flag. You cannot evaluate the cost of borrowing if you do not know what you are paying to borrow.
Red Flags in Loan Documents
Watch for these warning signs:
- "Amount financed" exceeds the system cost by 20% or more. The gap is likely a dealer fee.
- No line item showing origination charges, points, or fees. Silence in the fee section does not mean no fees exist — it often means they are buried in the principal.
- APR lower than the current prime rate. If the rate seems too good to be true, you are probably paying for it through a dealer fee.
- Pressure to focus on monthly payment rather than total cost. The monthly payment is designed to look manageable; the total of payments reveals the true cost.
FAQ
What is the typical dealer fee on a solar loan?
Dealer fees range from approximately 15% to 31% of the system cost, depending on the APR chosen. A 3.99% rate might carry a 25% fee; a 0.99% rate can carry a 30% to 31% fee.
Is the dealer fee the same as an origination fee?
Functionally similar, but structurally different. Dealer fees are paid by the installer to the lender for buying down the rate; origination fees on traditional mortgages are paid directly by the borrower. The difference matters because dealer fees are passed through to you without being called "borrower fees," making them harder to spot.
Can I negotiate the dealer fee?
Sometimes. If you are paying cash or using alternative financing, there is no dealer fee. If you must use the solar lender, asking for a higher APR (lower dealer fee) can reduce the upfront cost. The trade-off is higher monthly payments. Always compare total cost across all options.
What if the dealer fee was not disclosed to me in California?
Under SB 784, failure to disclose the dealer fee — in writing, as a dollar amount and percentage — is a statutory violation. You may have claims for rescission, damages, and attorney's fees. Consult a California consumer protection attorney.
Are dealer fees illegal?
Not inherently. The practice of buying down rates through upfront fees is common in consumer lending (mortgage points, for example). The problem is the lack of transparent disclosure. When consumers are told they are getting a "great rate" without being told they are paying thousands of dollars for it, the failure to disclose may cross into deception or fraud.
