Solar Loan Payoff and Refinance

If you own the panels, this is a debt problem

The installer sold you the panels and the financing in the same sitting, and the loan is the part that outlasts the sales pitch. Strip the roof out of the picture for a minute.

What you have is a fixed-term installment loan. The CFPB puts typical solar-specific loans at 8 to 25 year terms with stated APRs of 1 to 7 percent, usually repaid in 7 to 9 years because of prepayments. Some are secured by a lien on the panels themselves, some are unsecured.

That is a consumer loan wearing a green jacket, and the lender dressed it that way to sell it. The upside for you is that consumer loans have ordinary answers. The ownership question that torments lease and PPA holders does not apply: the panels are yours. What is left is the balance, the rate, and one trap the lender built into the structure.

The fee is spent. Stop trying to refinance it away

Find the number first. The gap between the cash price of your system and the loan principal is the dealer fee, and the dealer fee page walks through locating it in your paperwork.

Then be clear about what can and cannot be done with it. The fee went into your principal and was paid out at origination, before you ever saw a bill. It is in the balance. No refinance removes it, because a refinance pays off one balance with another. The CFPB’s own headline for its report on this market said lenders were cramming markup fees and confusing terms into solar energy loans, which tells you how the low advertised rate was paid for.

What a refinance changes is the rate and the term you carry that balance at, and on a 25-year loan that can matter a lot. Whether the fee should have been charged the way it was is a separate fight, and you should keep the two apart.

The month-19 cliff

This is the part most borrowers never had explained to them, and it is why a solar payment can jump without anyone changing the terms.

The CFPB found it commonplace for solar-specific loans to re-amortize at a higher monthly payment at the 19th month of the term if the borrower does not make a substantial prepayment before then, and that the necessary prepayment is frequently 30 percent of the loan principal, which was the current size of the federal Investment Tax Credit.

So the advertised payment was never the real payment. It was the payment that only works if you hand the lender roughly a third of the balance around month eighteen.

Here is that structure on the CFPB’s own average project cost of about $25,000, with a 30 percent dealer fee. The rate sits inside the 1 to 7 percent band the CFPB found on these loans. The arithmetic is ours.

Cash price of the system	$25,000
Dealer fee added to principal	$7,500
Loan principal	$32,500
Expected prepayment, 30 percent of principal	$9,750
Advertised monthly payment	$108
Payment from month 19 with no prepayment	$158
Total paid over 25 years, no prepayment	$46,537

A $50 increase arriving unannounced on a bill you were told would be $108, in month nineteen of a twenty-five year commitment, is how people discover what they actually signed.

The 2026 version of this is worse

That whole structure assumed the borrower would receive a 30 percent federal tax credit and pass it straight to the lender.

The IRS now says the Residential Clean Energy Credit is not available for any property placed in service after December 31, 2025. A system installed in 2026 gets no credit. If a loan is still being sold on the old shape, with a low teaser payment and a prepayment expectation in month nineteen, the money to make that prepayment does not exist.

The CFPB already flagged the softer version of this, noting that the credit is nonrefundable and depends on the borrower’s tax liability, so a household with little federal tax owed was never going to see the full amount anyway. The credit ending removes the question entirely.

If you are being quoted a solar loan right now, ask what the payment becomes in month nineteen if you make no prepayment, and get the answer in writing. If they will not put it in writing, walk away.

Three ways out, cheapest first

1. Complain about the fee. Free.

If your loan principal exceeds the cash price of your system and nobody explained the gap, you are looking at the exact pattern two state attorneys general have already sued over.

Minnesota sued GoodLeap, Sunlight Financial, Solar Mosaic and Dividend Solar Finance in March 2024 over roughly $35 million in hidden fees across nearly 5,000 loans, most of them raising borrowers’ costs by 15 to 30 percent. Michigan sued Climax Solar and its financing partners in July 2026, alleging more than $22 million in financing costs included in system prices without being disclosed as finance charges, with dealer fees averaging more than 27 percent of the amount financed.

File with your state attorney general, the CFPB and the FTC. It costs a stamp. It is also the only step in this category with a track record of producing restitution.

One thing to look for while you are gathering documents: the notice required by 16 CFR 433.2, stating that any holder of the consumer credit contract is subject to all claims and defenses which the debtor could assert against the seller, with recovery capped at amounts the debtor paid. If your contract carries it, the finance company cannot hide behind the installer when you raise what you were told.

2. Pay down before the reset, if you can

If month nineteen is ahead of you and you have the cash, making the prepayment avoids the re-amortization and the interest that rides on it. In the example above, prepaying keeps the total around $42,700 instead of $46,500.

That is a real saving, and it is also a large payment against a balance the dealer fee inflated. Make it only if the money is genuinely spare. The solar exit cost calculator will put paying down, refinancing and staying put side by side.

3. Refinance the balance

This is where you stop dealing with the lender the installer picked for you.

Treasury’s advice at purchase applies just as well afterwards: you are not required to use the financing offered by the salesperson, and you might get a better deal from your own bank or credit union, so shop around and compare lender fees. Compare the all-in cost of a new loan against what you are paying now, including what the payment becomes after any reset.

Two cautions. A home equity loan usually carries the lowest rate on offer, and it secures the debt against your house rather than against the panels. That trade can make sense, but make it knowing your house has become the collateral. And if you are also disputing the fee, be accurate with the new lender about the dispute, and do not let a refinance deadline pressure you into dropping it.

This page is the bridge out of the cluster. Once the panels are yours and the ownership question is settled, what is left is ordinary consumer debt, and the rest of the site handles that better than this cluster can. Compare consolidation and personal loan rates, pull three quotes, and judge on the blended cost rather than the monthly figure.

What not to do

Do not stop paying to force a negotiation. It is a real route and it has real consequences, laid out on its own page, but using it as a pressure tactic on a loan secured by the panels tends to cost more than it wins.

Do not pay a solar cancellation company to file the complaint in step one. These outfits market to exactly the borrowers this page is written for, and whatever they charge, the complaint form is free and you can fill it in tonight.

This is general information, not legal advice. Whether your fee was properly disclosed, and what your contract permits, turn on your documents and your state’s law, so put the installation contract and the loan agreement in front of an attorney licensed in your state before you decide what you have.
