Solar Loan Problems: What to Do When Your Solar Financing Goes Wrong

By the CredibleLaw Editorial Team  |  Updated September 24, 2026

The short answer Most solar loan problems trace back to how the loan was sold: undisclosed dealer fees, a payment that resets when an expected tax-credit paydown is not made, or sales promises the lender now disowns. Federal laws including the Truth in Lending Act, the FTC Holder Rule, and the Fair Credit Reporting Act, along with state consumer protection laws, may give you defenses or claims. If you can, keep paying while you gather your documents, and have the paperwork reviewed before you stop paying or sign anything new.

Solar loan problems usually surface months after the panels go up. The monthly payment suddenly jumps. The tax credit the salesperson promised never arrives, or turns out to be far smaller than described. The installer stops answering the phone. Or you finally read the loan statement and discover you owe thousands more than the price you were quoted.

If any of that sounds familiar, you are dealing with one of the most common consumer finance complaints in the country, and you have more options than the lender’s collection letters suggest. This guide explains the eight solar loan problems we see most often, the federal and state laws that may apply, and the practical steps that protect your position. Each section links to a deeper guide on that specific problem.

CredibleLaw is a San Diego-based legal referral network, not a law firm. We publish legal information and connect homeowners with independent attorneys and legal professionals who handle solar and consumer finance disputes. Nothing here is legal advice for your situation, and laws vary by state.

Why So Many Solar Loans Go Wrong

Most residential solar loans are sold at the kitchen table, not at a bank. A salesperson representing an installer or sales company pitches the system, then approves you for financing on a tablet in minutes through a lender the installer partners with. You may never speak to the lender until the first bill arrives. That three-party structure is the root of most disputes: the person who made the promises is not the company collecting the payments.

Federal regulators have documented the pattern. In its August 2024 Issue Spotlight on solar financing, the Consumer Financial Protection Bureau reported that hidden fees typically add 10 to 30 percent to the cash price of a system and can exceed 50 percent, that marketing often presented a “net” cost after an assumed tax credit, and that many loans re-amortize to a higher payment if a large prepayment is not made by a set date.

Two more recent developments have made things harder for homeowners. First, the federal Residential Clean Energy Credit (Internal Revenue Code Section 25D) ended for systems installed after December 31, 2025, according to IRS guidance on the 2025 tax law. Loans built around a tax-credit paydown now carry more risk than ever. Second, a wave of solar installer and lender bankruptcies has left many homeowners with a loan but no company to call about repairs or warranties.

The 8 Most Common Solar Loan Problems

Below is a summary of each problem and where to go for a complete explanation. If you recognize your situation, the linked guide covers the law, the evidence that matters, and the realistic outcomes in depth.

1. Your Solar Loan Payment Went Up

Many solar-specific loans set a low introductory payment on the assumption that you will pay down roughly 30 percent of the balance, typically with a tax refund, by around the 18th month. If that paydown does not happen, the loan re-amortizes over the remaining term. In a simplified example, a loan structured this way can jump to a payment roughly 40 percent higher, because it is now calculated on the full balance rather than on 70 percent of it.

An increase that follows the contract is not automatically illegal. The legal question is whether the reset was clearly disclosed and accurately explained when you signed. Our guide on why a solar loan payment went up explains how to read your amortization terms and when the increase may support a claim.

2. The Salesperson Misrepresented the Tax Credit

The most common misstatement we see is some version of “the government sends you 30 percent back.” The federal credit was nonrefundable: it could reduce income tax you owed, but it was never a check. Homeowners with little or no federal tax liability, including many retirees, often could not use most of it. Leased systems and power purchase agreements never qualified for the homeowner’s credit at all, because the homeowner does not own the equipment.

Now there is a sharper problem. Because the credit ended for installations completed after December 31, 2025, any 2026 pitch that promises a federal residential solar tax credit on a newly installed system is wrong. See our guide to solar tax credit misrepresentation for how these claims are evaluated.

3. Hidden Dealer Fees Inflated Your Loan Balance

A dealer fee is an amount the lender charges the installer to offer a low advertised rate, which is then built into your loan principal. The result can be a loan with a 1.99 percent APR on paper and a balance thousands of dollars above what a cash buyer would have paid. Whether those fees must be disclosed as a finance charge under the Truth in Lending Act is being litigated; it is a developing theory, not settled law.

State attorneys general have pursued dealer-fee practices, and private lawsuits continue. Our page on the solar loan dealer fee lawsuit covers how to find the fee in your paperwork and what the pending cases argue.

4. The Solar Company Went Out of Business

When an installer closes or files bankruptcy, the loan usually does not disappear, because it is owed to a separate lender. What often does disappear is the workmanship warranty, system monitoring, and anyone to fix a leaking roof penetration. The automatic stay in bankruptcy protects the bankrupt company, not the lender that holds your loan.

You may still have options: manufacturer warranties on panels and inverters often survive, you may be able to file a claim in the bankruptcy case, and depending on your contract you may be able to raise the installer’s failures against the lender. Read more in our guide to solar company bankruptcy and your loan.

5. The Lender Says the Salesperson’s Promises Are Not Its Problem

Under the FTC Holder in Due Course Rule, when a seller arranges consumer financing through a lender it works with, the credit contract must include a notice making the lender subject to the claims and defenses you could raise against the seller. When the rule applies, your recovery against the lender is generally limited to the amounts you have paid under the contract, but the defense can also reduce or cancel what you still owe.

Whether the rule reaches a particular solar loan depends on how the loan was arranged and what the contract says. Courts are divided on what happens when the required notice is missing. Our FTC Holder Rule for solar loans guide walks through the analysis.

6. You Want to Stop Paying Your Solar Loan

Stopping payments is the move homeowners most often consider and the one most likely to backfire if done without a plan. Missed payments can be reported to the credit bureaus, sent to collections, and lead to a lawsuit. Many solar loans are also backed by a UCC fixture filing recorded against your property, which can complicate a sale or refinance.

There are situations where withholding payment is part of a legal strategy, but that decision should follow a review of your documents, not precede it. Our guide on what happens if you stop paying your solar loan explains the consequences and safer alternatives, and our page on solar UCC lien removal covers the lien side.

7. The Solar Loan Is Wrong on Your Credit Report

The Fair Credit Reporting Act gives you the right to dispute inaccurate or incomplete information with the credit bureaus, which generally must investigate within 30 days, and it requires the lender to investigate disputes the bureaus forward to it. If a loan was opened with a forged signature or without your authorization, identity-theft blocking rights may also apply.

Accurate negative information, however, generally cannot be removed simply because you disagree with the loan. Our guide to disputing a solar loan on your credit report explains what can and cannot be corrected, and how to document the dispute.

8. Your Solar System Was Financed Through PACE

Property Assessed Clean Energy (PACE) financing is repaid through your property tax bill rather than a monthly loan payment. Because it is a tax assessment, falling behind can put the home itself at risk under your state’s property tax collection laws, and the assessment generally takes priority over your mortgage. Residential PACE has operated mainly in California, Florida, and Missouri.

A federal rule that took effect March 1, 2026 treats residential PACE as credit under the Truth in Lending Act and requires an ability-to-repay determination for covered transactions. Older assessments are governed mainly by state law. See our PACE solar loan help guide for details.

Is It a Legal Problem or Just a Bad Deal?

Honesty matters here, because the wrong expectations cost homeowners time and money. Not every solar loan problem is a legal claim. A loan that turned out to be more expensive than you hoped is not, by itself, grounds to sue. Contracts that clearly disclosed the price, the rate, and the payment reset are usually enforceable even when the system underperforms.

A problem is more likely to have legal weight when one or more of the following is true:

• What you were told contradicts what you signed, and you can show it with texts, emails, marketing materials, or a witness.
• Key terms were never shown to you, for example the contract was signed on a tablet that was swiped through quickly, or documents were e-signed in a way you did not authorize.
• The loan balance exceeds the cash price and the difference was not explained.
• The installer failed to perform, such as never obtaining permission to operate, damaging the roof, or abandoning the job.
• You are an older homeowner, a non-English speaker, or were pressured to sign in a single visit, circumstances that some state laws treat with particular concern.

If your situation is primarily about the contract itself rather than the financing, our guides on how to cancel a solar contract and solar contract dispute lawsuits may be the better starting point.

Federal and State Laws That Protect Solar Borrowers

No single law governs solar loan problems. Instead, several overlapping protections may apply depending on how your loan was structured and sold.

• Truth in Lending Act (TILA) and Regulation Z. Require accurate disclosure of the APR, finance charge, amount financed, and payment schedule. For loans secured by your principal dwelling, TILA may also provide a right to rescind. The statute allows recovery of reasonable attorney’s fees in successful actions, which is one reason consumer attorneys can take these cases.
• FTC Holder Rule (16 C.F.R. Part 433). May let you raise the seller’s misconduct as a defense against the lender, as described above.
• FTC Cooling-Off Rule (16 C.F.R. Part 429). Generally gives three business days to cancel qualifying sales made at your home. Many states provide longer or additional cancellation rights.
• Fair Credit Reporting Act. Governs how the loan is reported and how disputes must be investigated.
• State consumer protection (UDAP) laws. Every state prohibits unfair or deceptive business practices, and many allow homeowners to sue directly. Some also provide enhanced remedies when the victim is an older adult.
• State home solicitation and contractor laws. Many states regulate door-to-door sales and require solar contractors to be licensed, which can matter when a salesperson or installer was not.
• CFPB PACE rule. Applies Truth in Lending protections and an ability-to-repay requirement to covered residential PACE transactions.

Two practical cautions apply across all of these laws. First, deadlines matter: some TILA damages claims must be brought within one year, while other claims have longer limits, and the clock may run from signing or from when you discovered the problem. Second, most solar loan agreements contain arbitration clauses and class-action waivers, which affect where and how a dispute is resolved. An attorney can tell you which deadlines and forums apply to you.

What to Do First: 7 Steps to Protect Yourself

Whatever the specific issue, the same early steps protect you in almost every solar loan problem. None of them commits you to a lawsuit.

1. Keep paying if you reasonably can while you evaluate your options. It preserves your credit and your flexibility.
2. Request your complete loan file from the lender in writing, including the signed loan agreement, the Truth in Lending disclosures, the amortization schedule, and any payment-reset terms.
3. Get the installation contract from the installer or sales company, including any change orders and the savings or production estimate you were shown.
4. Write down what you were told, with dates and names, while it is fresh. Note who was present.
5. Save every communication, including texts, emails, voicemails, marketing flyers, and the salesperson’s business card.
6. Pull your credit reports from all three bureaus to see how the loan is being reported.
7. Do not sign anything new, such as a loan modification, a settlement release, or a transfer agreement, until someone independent has reviewed it.

Documents to Gather Before a Case Review

An attorney can evaluate solar loan problems far more quickly with the right paperwork. You do not need all of it to start, but the more you have, the more specific the guidance can be.

• The signed loan agreement and all Truth in Lending disclosures
• The solar installation or purchase contract and any addenda
• The savings, production, or tax-credit estimate you were given
• Recent loan statements and any notice of a payment change
• Your utility bills from before and after installation
• Your tax return for the installation year, if you attempted to claim a credit
• Photos of the system and any roof or property damage
• Any recorded lien or UCC filing, if you have found one
• Correspondence with the installer, lender, and any regulator

Mistakes That Make Solar Loan Problems Worse

A few understandable reactions can turn a manageable solar loan problem into a much harder one.

• Paying a “solar cancellation” company large upfront fees. Some of these businesses charge thousands of dollars for form letters a homeowner could send alone. Ask whether you are dealing with a licensed attorney, and how fees are structured, before you pay anything.
• Stopping payment without a strategy. It can turn a strong position into a collection case.
• Ignoring letters from the lender or a court. Missing a deadline to respond to a lawsuit can lead to a default judgment.
• Removing the panels yourself. This can breach the contract, void warranties, and create roof damage that becomes your responsibility.
• Agreeing to a “fix” by phone. Loan modifications and settlements should be in writing and reviewed before you accept them.

When to Talk to a Solar Loan Attorney

You can handle some solar loan problems on your own, such as a straightforward credit report dispute or a warranty claim with a panel manufacturer. It is worth speaking with an attorney when the balance is significant, when you believe you were misled about the loan or tax credit, when the installer has disappeared, when a lien is blocking a sale or refinance, or when you have received a demand letter or lawsuit.

Cost is a common concern. Because TILA and many state consumer protection laws allow a successful homeowner to recover attorney’s fees from the other side, some consumer attorneys handle these matters on a contingency or fee-shifting basis. Arrangements vary, so ask about fees in your first conversation. For a broader look at when legal help makes sense, see our solar fraud attorney guide.

Frequently Asked Questions About Solar Loan Problems

What are the most common solar loan problems?

The most common solar loan problems are a payment increase after an expected tax-credit paydown is not made, misrepresentations about the federal solar tax credit, hidden dealer fees that raise the loan balance above the cash price, an installer that goes out of business, a lender that refuses responsibility for sales promises, and credit reporting errors. PACE assessments on property tax bills raise their own issues. Many homeowners face more than one of these at the same time.

Why did my solar loan payment go up?

Many solar loans set a lower introductory payment on the assumption that you will pay down about 30 percent of the balance, often with a tax refund, by around the 18th month. If that prepayment is not made, the loan re-amortizes and the payment rises. Whether that increase is legally challengeable depends on how clearly it was disclosed and explained when you signed.

Can I get out of a solar loan?

Possibly, depending on the facts. Options may include a cancellation right if the sale was recent, a defense under the FTC Holder Rule if the seller misled you, claims under the Truth in Lending Act or state consumer protection laws, or a negotiated settlement. Paying off or refinancing the loan is also an exit. An attorney can review your documents to see which options realistically apply.

What happens if I stop paying my solar loan?

Missed payments can be reported to the credit bureaus, sent to collections, and lead to a lawsuit and judgment. If the loan is supported by a UCC fixture filing, the filing may complicate a sale or refinance of your home. Withholding payment is sometimes part of a legal strategy, but it should follow a review of your documents rather than precede it.

Is the solar lender responsible for what the salesperson promised?

Sometimes. Under the FTC Holder Rule, when a seller arranges financing through a lender it works with, the credit contract must preserve your claims and defenses against the seller, making the lender subject to them. Recovery against the lender is generally capped at what you have paid. Whether the rule applies to your loan depends on how the loan was arranged and the contract language.

What is a dealer fee on a solar loan, and is it legal?

A dealer fee is a charge the lender imposes on the installer to offer a low advertised interest rate, which is then built into your loan principal. The CFPB reported in 2024 that these fees typically add 10 to 30 percent to the cash price. Dealer fees are not automatically illegal, but whether they must be disclosed as a finance charge is actively being litigated.

The solar company went out of business. Do I still have to pay the loan?

Usually, yes, because the loan is typically owed to a separate lender rather than to the installer. However, you may be able to raise the installer’s failures against the lender under the FTC Holder Rule, file a claim in the installer’s bankruptcy case, and rely on manufacturer warranties that survive the installer’s closure. The right path depends on your contract.

Can I still get the 30% federal solar tax credit in 2026?

No, not for a newly installed home system. Under the 2025 federal tax law, the Residential Clean Energy Credit under Section 25D is not allowed for expenditures made after December 31, 2025, and the IRS treats an expenditure as made when installation is completed. A salesperson promising this federal credit on a system installed in 2026 is misstating the law.

Can I remove a solar loan from my credit report?

You can dispute information that is inaccurate or incomplete, and the credit bureaus generally must investigate within 30 days. If the loan was opened through a forged signature or without your authorization, identity-theft protections may allow the account to be blocked. Accurate negative information, such as payments you actually missed, generally cannot be removed simply because you dispute the underlying loan.

How is a PACE solar loan different from a regular solar loan?

PACE financing is repaid through your property tax bill as an assessment on your home rather than through a monthly loan payment. Falling behind can trigger property tax collection remedies, and the assessment generally takes priority over your mortgage. Since March 1, 2026, a federal rule has treated covered residential PACE transactions as credit under the Truth in Lending Act, with an ability-to-repay requirement.

Do I need a lawyer for a solar loan problem, and what does it cost?

Not always. You can handle a simple credit report dispute or manufacturer warranty claim yourself. A lawyer is worth consulting when the balance is significant, you were misled, the installer is gone, a lien is blocking a sale, or you have been sued. Because some consumer protection laws let a successful homeowner recover attorney’s fees, some attorneys work on contingency or fee-shifting arrangements.

How long do I have to take legal action over a solar loan?

It depends on the claim and your state. Some Truth in Lending Act damages claims must be filed within one year, while state consumer protection, fraud, and contract claims often have longer limits. Some deadlines run from the date you signed and others from when you discovered the problem. Because deadlines can bar a claim entirely, it is wise to have your situation reviewed promptly.

Where can I file a complaint about a solar lender?

You can file complaints with your state attorney general’s consumer protection division, your state financial regulator, and the Consumer Financial Protection Bureau’s online complaint portal. Complaints about the installer may also go to your state contractor licensing board. A complaint does not replace legal action or stop a deadline from running, but it creates a record and sometimes prompts a response.
