Solar Loan Comparison: How to Avoid Hidden Fees and Scams

Disclaimer: This article is informational, not legal advice.

Overview

Financing a solar panel system is a major financial commitment, often functioning like a second mortgage. Unfortunately, the solar financing industry is fraught with confusing terms, hidden dealer fees, and deceptive sales pitches. Comparing solar loans is not as simple as looking for the lowest interest rate. This guide explains the different types of solar loans, how to calculate real costs, and the red flags to watch out for.

Key Points

Low-interest solar loans often include massive hidden "dealer fees" that inflate the principal amount by up to 30%.
Unsecured loans are tied to you personally, while secured loans (like PACE or home equity) are tied to your property.
Major solar lenders (GoodLeap, Mosaic, Sunlight) often rely on sales reps to explain loan terms, leading to misrepresentations.
Getting an independent loan from a local credit union is often much cheaper in the long run.

Types of Solar Loans

There are several ways to finance a solar purchase:

Unsecured Solar Loans Offered by specialized lenders like GoodLeap, Mosaic, and Sunlight Financial. They don't require collateral, but if you default, they can damage your credit. They often use UCC-1 fixture filings, which aren't liens on the home but can still complicate a sale.
Secured Loans (Home Equity/HELOC) You borrow against the equity in your home. These typically have lower fees and interest rates, but if you default, you risk losing your home.
PACE Loans (Property Assessed Clean Energy) These are attached to your property tax bill. They can be very dangerous because they take first-lien position over your mortgage, making it extremely difficult to sell or refinance the home.

The Hidden Trap: Dealer Fees

The biggest scam in solar financing is the "dealer fee." Salespeople often pitch an incredibly low interest rate, like 1.99% or 2.99%, making the monthly payment look attractive. However, to offer that low rate, the lender charges the solar installer a massive upfront fee—often 20% to 35% of the total project cost. The installer simply adds this fee to the principal amount of your loan. If you try to pay the loan off early, you are still stuck paying that inflated principal.

Target Payments and the Tax Credit Illusion

Most solar loans are structured with an initial low monthly payment that assumes you will apply your 30% Federal Solar Tax Credit directly to the loan balance by month 16 or 18. If you do not qualify for the full tax credit, or if you choose not to apply it to the loan, your monthly payment will abruptly spike—often by 30-50%—for the remainder of the 20-25 year term. Salespeople frequently fail to explain this "re-amortization" trap.

Comparing Lenders: GoodLeap, Mosaic, Sunlight, and Credit Unions

The major point-of-sale lenders (GoodLeap, Mosaic, Sunlight Financial, Dividend) approve loans instantly via a salesperson's tablet. While convenient, their dealer fees are notoriously high. Before signing with one of these lenders, you should always request a quote for a "cash price" without financing attached. Then, take that cash price to a local credit union or bank. Even if the credit union offers a higher interest rate (e.g., 7-8%), the lack of a 30% dealer fee often makes it a much cheaper loan overall.

Red Flags in Solar Financing

Beware of salespeople who try to rush you through the loan documents on their personal tablet without letting you read them. Watch out for promises that the government will send you a check to pay down the loan, and be wary of any contract where the cash price is vastly different from the financed principal.

Stuck Paying a Solar Loan for a System That Does Not Produce or Work?

The solar salesperson was paid. The installer was paid. The finance company drafts money from your account every month. And when you look for a solar lawyer, the conversation often turns to retainers, hourly rates, and money upfront.

Before paying a lawyer out of pocket, there is a critical question worth asking:

“Could any applicable law, based on your facts and jurisdiction, allow attorney fees to be sought from the other side?”

Asking you to pay is simple. Evaluating potential statutory fee-shifting under state UDAP laws, TILA, and deceptive trade practices requires investigating your actual contract and disclosures.

What To Do Next

Never sign a financing agreement on the same day as the sales pitch. Always ask for the cash price versus the financed price so you can calculate the exact dealer fee. Seek pre-approval from a local credit union for a home improvement loan to compare terms, and read the fine print regarding what happens to your payment if you don't apply the tax credit to the principal.

FAQ

What is a dealer fee on a solar loan?

A dealer fee is an upfront cost charged by the lender to the solar installer in order to buy down the interest rate. The installer passes this cost to you by inflating the total loan amount, sometimes by as much as 30%.

Are PACE loans a good idea for solar?

Generally, no. PACE loans attach to your property taxes and take priority over your mortgage. This makes selling or refinancing your home extremely difficult, as most mortgage lenders (like Fannie Mae and Freddie Mac) will not approve loans on properties with PACE liens.

Why did my solar loan payment suddenly increase?

Your loan likely required a "target payment" based on the assumption that you would pay down 30% of the principal using your federal tax credit by a specific date. If you didn't make that lump-sum payment, the loan re-amortized at a higher monthly rate.

Question Fee-Shifting

Asking for a retainer is simple. But state UDAP laws, TILA § 130, and consumer statutes often allow attorney fees to be sought from the fraudulent company.

The solar salesperson may have been paid. The installer may have been paid. The finance company may be taking money from you every month. And now you have reason to believe something is seriously wrong.

So you Google: “Solar fraud lawyer.” And what happens next? You tell someone your story. They ask a few questions. And eventually, the conversation turns to: How are you going to pay for legal services? Retainer. Hourly rate. Money upfront.

Those arrangements may be appropriate in some matters. But before assuming that paying a lawyer is your only option, ask: “Could any applicable law, based on the facts and jurisdiction, allow attorney fees to be sought from the other side?”

The answer depends on the law, the contract, the claims available, the evidence, and the outcome. Asking you to pay is simple. Evaluating potential fee-shifting requires investigating your contract, financing terms, utility bills, texts, cancellation attempts, and consumer-protection statutes.
