"Buying a Home with Solar Panels: How Do I Check the Contract Before I Make an Offer?"

The short answer: ask for the solar agreement itself before you write the offer, because which of five arrangements it turns out to be decides three separate things — whether a monthly payment lands on your loan application, whether something is recorded against the title that has to be moved before closing, and whether the panels count toward the appraised value. A seller's description of the panels is not the document. The document is what underwriting reads.

I'm Jeff Moran, a mortgage broker in Bluffton, South Carolina, originating since 1996, NMLS #483943, through C2 Financial Corporation, licensed in fifteen states. Panels turn up on more listings every year, and the question almost always arrives at the wrong time. The buyer is three weeks into the file, the appraisal is back, and somebody finally reads the agreement and finds eight years left on it. Nothing about that is hard. It is only late.

Why the panels are a paperwork question before they are a power question

Most people looking at a house with solar are asking whether the electricity is cheaper. That is a fair question, and it is the second one. The first is who owns the equipment. Panels can be owned outright, owned with a loan against them, owned with a loan secured by the house itself, or not owned by the homeowner at all. Those are different arrangements with different consequences, and they look identical from the driveway.

Freddie Mac's Seller/Servicer Guide sets out the treatment for each in Section 5601.4, "Eligibility of properties with energy-efficient improvements and properties with solar panels," revised 01/26/2026. It directs the lender to consider ownership of the panels and any liens relating to the debt or lease payments behind them, and to review the UCC-1 financing statement or lease agreement to see whether a filing runs against the real estate or only against the panels. Other agencies and individual lenders keep their own standards, so the specifics on your file come from whoever funds it. The shape of the question does not change.

That is why the agreement is the thing to ask for. Not the utility bill, not the installer's brochure. The agreement.

What are the five ways solar panels can be attached to a house?

Arrangement	Who owns the panels	What the buyer takes on
Power purchase agreement (PPA)	A third party	Buys the power produced, at an agreed price, owning no equipment
Lease	A third party	Pays monthly for access to the panels, owning no equipment
Financed as personal property	The homeowner	Owns the panels under a note and security agreement
Financed as a fixture to the real estate	The homeowner	Owns the panels, financing attached to the house
Owned free and clear	The homeowner	Owns the panels, no related debt

Only the last row costs a buyer nothing to take over. The other four each carry something, and the something is different in each case.

Which arrangement puts a payment on my application?

This is the part that changes what house you can buy, so it is worth being precise.

Where the panels were financed — as personal property or as a fixture to the real estate — the payment to the solar company or lender is included in the debt-to-income ratio. It behaves like a car loan. If that obligation is being left behind for you to assume, it takes up room in your ratio, and that room comes out of the price.

Where the arrangement is a lease or a PPA, the payment can sometimes be excluded, and the conditions are narrow. Section 5601.4 allows a lease payment to be left out when the lease provides for delivery of a specific amount of energy for an agreed payment during a given period and includes a production guarantee that compensates the homeowner on a prorated basis when production falls short of the level the lease requires. A PPA payment can be left out when it is calculated only on the energy actually generated.

A lease with a fixed payment and no production guarantee is an obligation. A lease that charges only for delivered energy, with a guarantee behind it, is closer to a utility bill. Same roof, same panels, different answer.

None of this says where you personally stand. It describes how a payment gets counted. What it means for your own numbers depends on your income, your other obligations and the price you are working toward, which is what the Debt Ratio tool is for and what debt-to-income measures.

What gets recorded against the title, and who has to clear it?

A UCC-1 financing statement is a public notice that a lender has an interest in specific property. With solar it can be written two ways, and the difference decides whether anybody has to act before your closing.

A filing claiming an interest in the panels only is the ordinary case for a lease or a PPA. Section 5601.4 does not require a subordination agreement for it, because it does not attach to the real estate.

A filing recorded against title that creates a lien on the real estate itself is a different matter. That one has to be subordinated or released. Where panels were financed as personal property, the guide is stricter: there must be no UCC-1 recorded against the property at all, and if one exists, it must be released.

Subordinating or releasing a filing means a third party you have never met has to sign something, and that takes days at best. It is the most common reason a solar file closes late, and it is avoidable, because the title search that finds the filing can be ordered early rather than at the usual point in the contract-to-closing sequence.

Two more provisions in that section protect the buyer, and almost nobody asks about them:

• Damage is the equipment owner's problem. Damage from installation, malfunction or removal of the panels falls on whoever owns the equipment, and that owner must be obligated to repair it and return the house to its prior condition.
• The solar company does not go on your homeowners policy. The owner of the panels agrees not to be a loss payee or named insured on the homeowners insurance covering the property. Your policy stays yours, which matters when you are already working through an insurance quote that came in high.

Does the appraiser add the panels to the value?

Not always, and this catches people who assumed the panels were worth something at the closing table.

Under Section 5601.4, panels under a lease or a PPA must not be included in the appraised value. The appraiser identifies them, notes the system features, and comments on marketability with panels present, but the value does not move for equipment somebody else owns. Panels financed as personal property are also excluded where the lender can repossess them on default.

Where the homeowner owns the panels, the appraiser is expected to recognize they exist and consider them in the opinion of market value, like any other property feature. What that contribution amounts to is a market question answered with local sales, not a number anyone can promise in advance. How appraisals work covers that distinction.

So a leased system can raise your monthly obligation without raising the appraised value. That is not a reason to walk away. It is a reason to know before you price your offer.

What to ask for before you write the offer

Ask the listing agent, in writing, early enough that the answer comes back while you can still change your number.

1. The solar agreement itself. The full lease, PPA, or note and security agreement. Not a summary, not a screenshot of the payment.
2. The transfer terms inside it. The Federal Trade Commission's consumer guidance on residential solar tells homeowners to establish before signing whether the contract can be transferred to a buyer, whether written notice to the company is required, and whether the buyer must meet credit requirements or pay a fee. Those are the same three answers you need on the other side of the transaction.
3. A recent electric bill, plus the solar bill. Two pieces of paper, and together they show what the house costs to run.
4. The remaining term and the end-of-term options. The Department of Energy's guide to solar leases, loans and PPAs tells homeowners to confirm whether the agreement can be renewed, whether the system can be purchased, whether it can be removed at the end of the term, and what each option costs.
5. Whether the seller will pay it off. On a financed system that is a normal thing to negotiate, like any other lien, and far easier to raise in the offer than in week three.

If the seller cannot produce the agreement, that is information too. Somebody signed a twenty-year contract and cannot find it, which means the payoff, the transfer clause and the term are all unknown to the person selling you the house.

Common mistakes

• Taking "they're paid off" as the answer. Sellers believe this in good faith and are sometimes wrong, because a loan against the panels and a loan against the house feel the same when you write the check. The payoff statement settles it. Nothing else does.
• Waiting for the lender to raise it. It comes up when the title work comes back, after the price is agreed and after the inspection period has started running.
• Treating the solar payment as a utility bill. Some of them are. A financed system is an obligation and is measured like one.
• Assuming the panels add to the appraisal. On a leased or PPA system they are specifically excluded from value.
• Leaving the transfer to the closing attorney. The solar company is a third party with its own process and timeline, and it does not know your closing date exists.

An illustration

Numbers below are made up to show the mechanism. They are not a quote and not a prediction.

Two houses, same price, same loan, both with panels. The first system is owned free and clear. The second was financed, with $138 a month left on it for another nine years.

Line	Owned outright	Financed, assumed by the buyer
Principal and interest	$2,410	$2,410
Property taxes	$310	$310
Homeowners insurance	$240	$240
Solar obligation counted in the ratio	none	$138
Monthly obligation the file measures	$2,960	$3,098

The second house is not a worse house. It is a different monthly number, and $138 a month of ratio is real buying power that has to come from somewhere. A buyer who knows before the offer can ask the seller to pay the system off, adjust the price, or decide the panels are worth it. A buyer who learns it after the appraisal is negotiating from behind, with a clock running.

Common questions

Do solar panels make it harder to get a mortgage on the house?

Usually no. Panels are a documentation and title question rather than a reason a house cannot be financed. What changes is the paperwork: the lender reviews the agreement, checks whether any filing runs against the real estate, and treats the payment according to the arrangement. Files with panels close every day. The ones that run late are the ones where nobody asked for the agreement until the title search turned up a filing.

Can I assume the seller's solar lease?

Often, but the agreement decides, not the purchase contract. Most leases and power purchase agreements contain a transfer clause, and it commonly requires written notice to the solar company, a credit check on the buyer, and sometimes a transfer fee. The FTC's consumer guidance tells homeowners to confirm those exact terms before signing, which is why they are knowable from the document itself. Read the clause before you write the offer, and start the company's transfer process the day you go under contract rather than the week of closing.

Does a leased solar system count against my debt-to-income ratio?

It depends on how the lease is written. Freddie Mac's Section 5601.4 permits a lease payment to be excluded when the lease delivers a specific amount of energy for an agreed payment over a given period and carries a production guarantee that compensates the homeowner on a prorated basis if output falls short. A power purchase agreement payment can be excluded when it is calculated only on the energy actually generated. A flat monthly payment without those features is treated as an obligation. Give your lender the agreement early and get the answer in writing.

What is a UCC-1 filing on solar panels, and does it cloud my title?

It is a public notice that a company has an interest in property. On solar it can claim an interest in the panels alone, or in the panels and the real estate together. A filing against the panels alone is ordinary and generally does not require a subordination agreement. A filing that creates a lien on the real estate has to be subordinated or released before the loan closes, and where panels were financed as personal property the guide requires that no filing be recorded against the property at all. Your title company finds these, and asking them to look early is free.

Who is responsible if the panels damage the roof?

Under Section 5601.4, damage from installation, malfunction or removal of the panels is the responsibility of whoever owns the equipment, and that owner must be obligated to repair it and restore the improvements to their prior condition. Separately, ask your home inspector to look at the roof penetrations and ask your insurance agent whether the carrier has a position on the system. Roof age and panel age together are a fair thing to raise in negotiation.

The one thing to do next

Email the listing agent and ask for the solar agreement and the last two electric bills. That one message answers most of this, and it takes about thirty seconds to send.

Then price the house with the real number. The documents a file needs are the same with panels as without, and the rate and scenario tools on the Solverya Lending Tools homepage will put a payment around it with no application and no credit pull. Bring the solar payment and you will be looking at the whole obligation, which is the only one worth writing an offer against.
