The Quick Read: The choice comes down to what the solar debt costs you today and what you would give up to move it. Rolling the loan into a new mortgage gives you one payment, but it resets your first mortgage and caps your leverage. Keeping the loan leaves your mortgage alone, but you carry two obligations.
Here is the honest answer on who each option is for. A cash-out refinance fits the homeowner whose existing first mortgage is no longer a prize, who has plenty of equity, and who wants one simpler debt. Keeping the solar loan fits the homeowner whose first mortgage is worth protecting, whose solar balance is small or nearly paid, or who may sell soon. Neither is the “smart” choice in the abstract. It depends on your file.
Key Takeaways
- Paying off a solar loan through a refinance counts as cash-out, even if no cash reaches you.
- Conventional cash-out is capped at 80% LTV on a one-unit primary home. LTV (loan-to-value) is the new loan divided by the home’s value.
- A PACE-financed system, repaid through your tax bill, has to be paid off at or before closing on conventional loans.
- FHA Streamline and VA IRRRL refinances are not built to pay off a solar loan.
- Keeping the loan means two payments but leaves your first mortgage untouched. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.

Side-by-Side
The table compares the two paths on the points that decide eligibility. It leaves out pricing on purpose. Your Loan Estimate shows pricing for your actual file.
| Factor | Cash-Out Refinance | Keep the Solar Loan |
|---|---|---|
| What happens to your first mortgage | Replaced by a new loan | Stays as is |
| Leverage | 80% LTV, one-unit primary home | No new leverage test |
| Credit floor | Conventional starts at a 620 score | None for the existing loan |
| Mortgage insurance | Required above 80% LTV | Not triggered |
| Occupancy | Lower caps on second homes | Not applicable |
| Documentation | Full income, asset, appraisal file | None beyond payments |
| Collateral | Solar debt moves onto the house | Depends on how the loan is secured |
| Seasoning | Existing first mortgage must be 12 months old | Not applicable |
Seasoning is the waiting period a lender wants before you can refinance. On conventional cash-out, the first mortgage being paid off must be at least 12 months old. A borrower must also have been on title for 6 months, with exceptions for delayed financing, inheritance and legal awards. These figures are subject to lender guidelines and full file review.
How a Cash-Out Refinance Absorbs a Solar Loan
A cash-out refinance replaces your first mortgage with a new, larger one. The solar balance gets paid off from the new loan’s proceeds. Across the wholesale programs Lendmire places files with, that payoff is treated as cash-out because the money pays a debt that was not part of buying the home.
That label surprises people. You may receive no check at all, yet the loan is still cash-out. It follows the cash-out leverage cap, not the higher limits on a refinance. A rate-and-term refinance, which only replaces your existing mortgage, can reach 95% LTV on a one-unit primary residence. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
Run the percentages. Say your first mortgage sits at 70% of your home’s value and the solar balance is 5%. The new loan lands near 75%, inside the cap before closing costs. Now say your first mortgage sits at 78% and the solar balance is 5%. The new loan lands near 83%, over the 80% cap. Same solar loan, different answer, because leverage decides.
Fannie Mae’s limited cash-out rules allow only a purchase-money subordinate lien to be paid off and included in the new loan. An unrelated solar loan is not a purchase lien. The guide does not mention solar loans by name, so treat this as the general rule. The Fannie Mae Eligibility Matrix sets the cash-out cap at 80% on a one-unit principal residence and 75% on a two- to four-unit principal residence.
If you are comparing this against other equity routes, Lendmire’s piece Shared Equity vs Cash-Out Refinance for a Homeowner Who Plans to Stay covers a different way to use equity. Lendmire’s cash-out refinance programs page lays out how the conventional lane is structured.
When a Cash-Out Refinance Is the Better Fit
A cash-out refinance tends to win in a handful of situations.
- Your current mortgage is not worth protecting. If replacing it costs you little in terms, folding in the solar debt is easier to justify.
- The solar loan is expensive or confusing. Many solar-specific loans carry dealer fees baked into the balance. More on that below.
- You want one debt. One payment, one servicer, one set of terms.
- You have real equity. After the payoff, the new loan still needs to land at or under 80% LTV on a one-unit primary home.
- Your debt-to-income ratio is tight. Paying off the solar loan drops its payment out of your ratios, though the larger mortgage replaces it. The automated finding on most conventional files allows a total ratio up to 50%.
- You plan to stay. A longer horizon gives the refinance time to earn back its closing costs.
Plan for the tradeoffs. You spread the solar balance over the new mortgage’s term. A debt you might have finished soon becomes part of a long-term loan. That lowers the monthly burden but can raise lifetime cost. You also pay refinance closing costs, and mortgage insurance applies if the new loan runs above 80%. Mortgage insurance can be cancelled at 80% of original value on request, and it ends automatically at 78%, under the Homeowners Protection Act. Each of those terms depends on your file.
There is also a collateral shift. Some solar loans are unsecured or only lightly secured. Move that balance into your mortgage and a missed payment now puts the house at risk. That is a real change in consequences, not just a tidier statement.
One more point on the wholesale side. A lane exists that reaches 89.99% LTV with no mortgage insurance at a 680 score and a 50% ratio on a 30-year fixed, primary residence, conforming balance. It carries its own six months of seasoning. Texas homestead cash-outs follow a state cap, and that lane is not written there. All of this is subject to lender guidelines.
When Keeping the Solar Loan Is the Better Fit
Keeping the loan wins more often than the refinance-focused pages suggest.
- Your first mortgage has strong terms. Replacing it to absorb a solar balance can cost you more than the solar loan ever did. Protecting a good first mortgage is a legitimate reason to leave it alone.
- The solar balance is small or nearly paid. The refinance’s closing costs and term reset can outweigh the benefit.
- You may sell soon. Closing costs need time to pay back. A sale often pays off the solar loan anyway.
- Your equity is thin. If the payoff pushes the new loan past the cap, the refinance does not work as designed.
- You are on FHA or VA financing. The streamlines are not built for this (details below).
- You can pay it down. Extra principal payments shorten the solar loan without touching your mortgage.
Check your loan agreement before settling in. The CFPB’s solar financing report found that many solar-specific loans effectively require a substantial partial prepayment. Those loans commonly re-amortize at a higher monthly payment in the 19th month if the prepayment does not arrive. The CFPB also reports that dealer fees often raise a solar loan’s cost by 30% or more above the cash price. If your loan has that structure, keeping it can mean a payment jump, and that can tip the decision back toward a refinance.
Keeping the loan also leaves you with two obligations. Both stay in your debt-to-income ratio if you apply for other credit. That matters if you plan to buy again or refinance later.
Solar Hazards That Change the Answer
Four issues come up on files like these, whichever path you pick.
The structure of the system. Is it owned outright, financed by a loan, leased, on a power purchase agreement, or paid through PACE? Conventional underwriting makes the lender confirm who owns the panels and how they are financed. Owned panels may count in the appraisal. Leased or PPA panels generally do not.
Liens. A solar lender may have filed a lien notice on the equipment, often called a UCC-1 filing. Title work finds it. On a refinance, that filing is either released after payoff or subordinated, which means the solar lender agrees to rank behind the new mortgage. Ask your solar lender for a current payoff statement and confirm the release in writing.
PACE. PACE (Property Assessed Clean Energy) loans are run by local programs and repaid through the property tax bill. They usually take priority over earlier mortgages. Fannie Mae’s PACE guidance is blunt: PACE-financed panels are not eligible for delivery to Fannie Mae unless the PACE balance is paid in full before or at closing. In practice, that makes PACE the case where a cash-out refinance is most likely to be the path, because paying it off is required.
The appraisal. If the appraiser values the system below what you paid for it, the new loan has less room than you expected. The inflated installed price hits the payoff balance but not the appraised value.
On taxes, the federal solar credit has its own rules. Tax treatment can depend on your situation; borrowers should speak with a qualified tax professional before relying on any deduction or credit.
What About FHA and VA Loans?
If your mortgage is government-backed, the fast refinance lanes will not absorb a solar loan.
The FHA Streamline refinances an existing FHA loan with limited credit review and a net tangible benefit test, which means the refinance has to help you in a measurable way. It is built to replace the FHA loan, not to fund other payoffs. The VA IRRRL does the same for an existing VA loan, with a 0.5% funding fee unless you are exempt and no VA appraisal. The VA’s refinancing chapter states that an IRRRL cannot take equity out or pay off debts other than the VA loan being refinanced.
A different product, a full FHA or VA cash-out refinance, could pay off solar. Those carry their own rules and a fuller file review. Your loan officer can tell you whether they fit your situation.
Key Terms Defined
Cash-out refinance: a new mortgage that replaces your current one and pays off other debts or gives you cash, within a leverage cap.
Limited cash-out (rate-and-term) refinance: a refinance that replaces your first mortgage and closing costs, with only incidental cash back.
LTV (loan-to-value): the new loan amount divided by the home’s appraised value.
Seasoning: the minimum time you must hold a loan or title before a lender will refinance.
UCC-1 filing: a public notice a solar lender may file to claim the equipment as security.
PACE: a local financing program repaid through your property tax bill, usually with priority over your mortgage.
Re-amortization: a recalculated payment schedule, often higher, triggered when a loan’s prepayment terms are not met.
A Practical Way to Decide
Work through it in order.
1. Identify the structure. Owned, loan, lease, PPA or PACE.
2. Pull the documents. The solar loan agreement, a current payoff statement, and any lien filing.
3. Check your leverage. Add the solar balance to your first mortgage and divide by your home’s value. If you land over 80% on a one-unit primary home, a conventional cash-out will not fit as designed.
4. Read the prepayment terms. Know whether and when your payment is set to jump.
5. Weigh your first mortgage. Decide whether its terms are worth protecting.
6. Think about time. Staying for years favors the refinance. Selling soon favors keeping.
A step to avoid: treating the solar loan’s monthly payment as the whole story. Term, collateral and lifetime cost matter as much.
The Balanced Verdict
Neither option wins by default. A cash-out refinance is cleaner when your equity is strong, your current mortgage terms are ordinary, and the solar loan is costly, complicated or tied to PACE. Keeping the loan is smarter when your first mortgage is valuable, the balance is small, or your plans are short.
The point most people miss is that this is a first-mortgage decision, not a solar decision. You are deciding whether replacing your mortgage is worth what it costs you. If you are weighing a cash-out refinance against keeping the loan you have, Lendmire can help you compare the programs and the equity each one reaches.
Frequently Asked Questions
Can I roll my solar loan into my mortgage?
Often, yes, through a cash-out refinance, if your equity supports it. The new loan has to stay within the cash-out leverage cap, which is 80% LTV on a one-unit primary home for conventional loans. Government-backed streamline products generally do not allow it. Program terms are subject to lender guidelines and full file review.
Is it still a cash-out refinance if I get no cash?
Yes. Paying off a debt that was not part of buying the home gives the loan cash-out treatment, even when no money reaches you. That changes the leverage cap, the seasoning requirements and the file review compared with a rate-and-term refinance.
What if my panels were financed through PACE?
Expect the PACE balance to be paid in full at or before closing on a conventional loan. PACE is repaid through your tax bill and usually ranks ahead of the mortgage. A cash-out refinance can be the route that pays it off, provided your equity supports the new loan.
Will I lose my current mortgage terms?
Yes, in a refinance. The new loan replaces the old one, with a new term, new costs and possibly mortgage insurance above 80% LTV. If you keep the solar loan, your first mortgage stays unchanged. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
What if the appraisal comes in below what the system cost?
The loan amount you can reach shrinks, because leverage is measured against appraised value. The solar payoff balance does not shrink with it. If the numbers no longer fit under the cap, keeping the loan or paying it down first may be the better path.
