Can You Refinance a Solar Loan? When It Makes Sense and How to Do It

Yes, you can usually refinance a solar loan. In practice you take out a new loan, such as a personal loan, a home equity loan or a cash-out mortgage refinance, and use it to pay off the solar lender in full. Whether you should refinance a solar loan depends on whether the new loan's total cost, including fees, is lower than what you still owe on the old one.

Key takeaways

• Refinancing is really an early payoff. Check your loan documents for any prepayment penalty first; EnergySage (updated October 2026) says most solar loans allow early repayment without one.
• Get a written payoff quote from your servicer. It, not your monthly statement, tells you the true balance.
• Many solar loans carried a dealer fee built into the balance. That fee is already sunk; refinancing only helps with the interest and payment from here.
• If a lender filed a notice against the panels or your property, it may need to be released or subordinated when you refinance a mortgage. Confirm the details with your lender.
• If your solar loan is unsecured, moving it onto your house turns it into debt secured by your home.

Why homeowners look to refinance a solar loan

People rarely refinance a solar loan just for a slightly lower rate. The usual triggers are a payment that is about to jump, a high balance caused by fees, or a desire to roll everything into one mortgage. The CFPB's August 2024 Issue Spotlight on solar financing explains why these situations are common:

• Planned lump sums. Many solar loans expect a large prepayment, often 30% of the principal, timed to a tax credit. If you skip it, the CFPB says many loans re-amortize at a higher monthly payment starting around month 19.
• Fees inside the principal. The CFPB found that dealer fees typically run 10% to 30% of the cash price and sometimes exceed 50%, so the balance can be much higher than the system's cash price.
• Early payoff is normal. The same report says solar loans with 8- to 25-year terms are usually repaid in 7 to 9 years because of prepayments.

The tax-credit gap is now a bigger issue. Per the IRS, the residential clean energy credit is not available for property placed in service after December 31, 2025. A homeowner whose loan was built around a credit they did not receive may face the higher re-amortized payment with no refund to soften it.

Your options to refinance a solar loan

There is rarely a dedicated "solar refinance" product. You choose a general type of credit and use it to pay off the solar lender.

Refinance route	Secured by your home?	Things to compare
Personal loan from a bank or credit union	No	APR, origination fee, fixed term, monthly payment
Home equity loan	Yes (second mortgage)	Fixed or adjustable rate, closing costs, term
HELOC	Yes (second mortgage)	Variable rate, draw and repayment periods, annual fees, any balloon payment
Cash-out mortgage refinance	Yes (first mortgage)	New mortgage rate versus your current one, closing costs, longer payoff period
Savings or a windfall	No	Lost interest and emergency cushion

The CFPB's HELOC booklet (updated September 2026) notes that HELOC rates are usually variable, that payments can change even if you do not borrow more, and that some plans require a balloon payment of the full balance at the end. Those features can make a HELOC a poor fit for paying off a fixed solar balance. For a fuller comparison, see home equity loan vs solar loan.

How to refinance a solar loan, step by step

1. Pull your original documents. Find the promissory note, the truth-in-lending disclosure and any security agreement. Look for prepayment terms and whether the loan is secured by the panels or by your home.
2. Request a payoff quote. Ask the servicer for a written payoff amount good through a specific date.
3. Check for filings on your property. A title search or your closing documents may show a UCC filing tied to the solar equipment.
4. Shop new credit in a short window. Get quotes from at least two or three lenders, including a local credit union.
5. Compare the total cost. Add up all remaining payments on the old loan and all payments plus fees on the new loan. A lower monthly payment over a longer term can cost more overall.
6. Close and confirm. After the payoff, ask the old lender for a paid-in-full letter and confirmation that any lien or filing has been released.

Liens, UCC filings and refinancing your mortgage

This is where solar debt most often trips up a refinance. The CFPB notes that lenders commonly file UCC liens on solar panels, and that these can cloud title and may need to be released or subordinated to a mortgage or refinance.

Fannie Mae's Selling Guide, updated November 4, 2026, spells out what a mortgage lender does. If a UCC fixture filing for financed panels is recorded in the land records, the lender must include that debt in your debt-to-income ratio and subordinate any fixture filing that is senior to the new mortgage. If the panels secure a separate loan with no fixture filing on title, the lender includes the debt in your ratios and gives the panels no value in the appraisal. In other words, an unpaid solar loan can follow you into a mortgage refinance even if you are not paying it off.

Leases and PPAs are different. Tesla, for example, says its leases and PPAs carry a UCC-1 statement on title as a notice that Tesla owns the system, and that a temporary release or subordination for a refinance carries a $150 fee where applicable (Tesla support page, checked November 2026). If you have a lease rather than a loan, you are not refinancing it; you would be buying it out. Our guide to solar leases vs buying explains the difference.

When refinancing a solar loan saves money and when it does not

Refinancing tends to help when:

• Your payment is about to re-amortize higher and you cannot make the lump-sum paydown.
• You can get a meaningfully lower APR without adding years to the payoff.
• You are already doing a cash-out refinance for other reasons and the solar balance is small relative to your equity.

It tends not to help when:

• The new loan has origination fees or closing costs that eat the interest savings.
• You stretch a few remaining years of payments into a 30-year mortgage. You may pay interest on the solar balance long after the panels' warranties expire.
• You move unsecured debt onto your home. The CFPB booklet reminds borrowers that with home equity credit, falling behind can cost you the house.

A simple test: write down the total of every remaining payment on your solar loan. Then write down the total of every payment and fee on the new loan. If the second number is not clearly lower, or the new loan adds risk to your home, the refinance is probably not worth it.

Watch for refinance and "debt relief" pitches

Homeowners with expensive solar loans sometimes get calls promising to cut their payment. Apply the same caution the FTC recommends for the original sale: do not sign anything you have not read, get every promise in writing, and verify the lender before sharing account details. If a solar lender misled you about fees or a tax credit, the CFPB accepts complaints online or at (855) 411-2372, and you can also contact your state attorney general.

Next steps

Start with a payoff quote and your original loan documents, then price at least two alternatives.
