A Peoria seller called me last spring, three days from closing, sounding a little rattled. The buyers loved the house. The inspection was clean. And then the lender flagged the rooftop solar — it wasn't owned, it was leased, and nobody had sorted out who was taking over the payments. What should have been a simple close turned into a week of phone calls with the solar company. It worked out, but it taught both sides a lesson worth passing on: in Arizona, solar panels are never just "a nice feature." They're a contract, a utility question, and sometimes a lien — and the answers change how a deal goes.
Rooftop solar is everywhere out here, and for good reason: we get some of the strongest sun in the country and some of the hottest summer bills. If you're buying or selling anywhere from North Peoria to Buckeye, there's a real chance solar is part of the conversation. Here's how to read it so it helps your deal instead of stalling it.
Step one: figure out how the solar is owned
Before anything else — before value, before savings — you need to know how the panels are owned. This single question decides how everything else works. There are three common setups in the West Valley.
Owned outright
The prior owner paid cash or has already paid off the system. This is the cleanest situation. Owned panels are considered part of the home, they generally transfer with the sale, and they're the version most likely to add value. If a seller tells you the system is "paid off," ask to see proof — a final payoff statement or the original purchase paperwork — so it can be confirmed before closing.
Leased or on a Power Purchase Agreement (PPA)
A third-party company owns the panels. With a lease you pay a fixed monthly amount to use the system; with a PPA you pay for the power it produces. Either way, the equipment isn't the homeowner's to sell. When the house sells, the buyer usually has to formally assume the contract — which often means passing a credit check, giving the solar company written notice, and sometimes paying a transfer fee. The other path is the seller buying out the remaining contract before closing, which can run into the tens of thousands depending on the term. According to the U.S. Department of Energy's consumer guidance, a third-party-owned system may require extra steps to transfer, and buyers should read the contract for transfer rules, notice requirements, and any fees before they commit (U.S. Department of Energy, energy.gov, accessed July 2026).
Financed with a solar loan
The homeowner bought the panels but is still paying them off. Here's the part that surprises people: many solar loans are secured by a UCC-1 fixture filing — essentially a lien on the equipment that can show up in the title search. That lien typically has to be paid off at closing (usually from the seller's proceeds) or formally handled so title can transfer clean. If you're selling, find out your exact payoff now, not the week of closing.
What owned solar does — and doesn't do — to your home's value
The honest answer: it depends on the setup. Nationally, homes with owned solar have tended to sell at a premium compared to similar homes without it, according to research summarized by the U.S. Department of Energy (energy.gov, accessed July 2026). That lines up with what we see locally — a paid-off system that visibly cuts a buyer's summer APS or SRP bill is a real selling point in a market where cooling costs are top of mind.
Leased and PPA systems are a different story. Because the homeowner doesn't own the equipment, appraisers generally can't assign it added value, and lenders treat it as a monthly obligation the buyer is taking on rather than an asset. Department of Energy data suggests third-party-owned solar adds some complexity to a sale but tends to be mostly neutral on price and time on market — as long as the transfer is handled correctly and early. The takeaway for sellers: owned solar can help your value story; leased solar is something to manage smoothly, not something to bank on as added equity. Because appraisal and lending treatment can vary by property and lender, verify how it applies to your specific home and loan.
How Arizona actually pays you for solar now
This trips up a lot of out-of-state buyers who think Arizona still has old-style "net metering," where every kilowatt you export offsets one you use. That changed years ago. Today the big utilities use net billing, where the credit you get for exported power is lower than the retail rate you pay — so the math on an existing system depends heavily on when and how it was set up.
- APS customers (much of the West Valley) are on an export-credit rider called the Resource Comparison Proxy (RCP). Legacy net-metering rates were grandfathered for up to 20 years from the date a system was first connected to the grid, and the RCP export rate a customer locks in is held for about 10 years from when they applied — after which it steps to the current rate (APS, aps.com, accessed July 2026).
- SRP customers are on separate solar-specific price plans with their own demand charges and export credits, which work differently from APS.
What this means in a transaction: the solar savings on a home you're buying are tied to that system's interconnection date and rate plan — not to whatever a solar salesperson quotes for a brand-new install. Always confirm which utility serves the address (APS and SRP both operate in the West Valley depending on the neighborhood) and ask for 12 months of actual utility bills. Because utility rates and solar rules change over time, verify the current terms directly with the utility before you count on any number.
Selling a West Valley home that has solar
The sellers who close smoothly are the ones who gather the paperwork early. Do this the moment you decide to list, not when you're under contract.
- Confirm the ownership type — owned, leased, PPA, or loan-financed — in writing.
- If it's owned: locate the purchase invoice and any payoff/warranty documents.
- If it's financed: request a current payoff amount and ask whether a UCC-1 lien is on file.
- If it's leased or PPA: call the solar company and ask exactly how a transfer works — buyer qualification, notice, fees, and the buyout figure.
- Gather 12 months of utility bills so buyers can see real production and savings.
- Tell your agent up front so the listing, disclosures, and contract handle the solar correctly from day one.
Arizona's residential purchase contract requires honest disclosure of what conveys with the property. Solar that's leased or financed doesn't simply "come with the house" — the terms have to be spelled out so buyers and their lender aren't surprised.
Buying a West Valley home that already has solar
Solar can be a genuine plus — you just want to buy with your eyes open. Before you write the offer, get clear answers to these:
- Owned, leased, or financed? Ask for documentation, not just a verbal answer.
- If leased/PPA: what's the monthly payment, how many years remain, and what does assuming the contract require of you?
- If financed: is there a lien that will be cleared at closing?
- What do the last 12 months of bills actually look like for this system on this utility plan?
- Who services the panels and roof, and does any warranty transfer to you?
- How old is the roof under the panels? Removing and reinstalling panels for a roof replacement is an added cost worth knowing about.
Loop in your lender early too. A leased or financed system can affect how a mortgage is underwritten, so it's better to raise it during pre-approval than to discover it days before closing — exactly the situation my Peoria sellers ran into.
A quick local example
A couple moving up to a larger home in Vistancia found a place they loved that had a four-year-old leased solar system. Instead of treating it as a dealbreaker or ignoring it, we called the solar company during the inspection period, got the transfer requirements and the remaining term in writing, and confirmed the monthly payment against the seller's actual bills. The buyers decided the after-solar cost still worked for them, assumed the lease with the paperwork done ahead of time, and closed on schedule. The panels weren't the problem — the unknowns would have been. Getting them answered early is the whole game.

Frequently asked questions
Do solar panels add value to a home in the West Valley?
Owned (paid-off) systems have tended to sell at a premium versus comparable homes without solar, according to U.S. Department of Energy research (energy.gov, accessed July 2026), and a system that clearly lowers summer cooling bills is a real draw here. Leased and PPA systems generally aren't counted as added appraised value because the homeowner doesn't own them. Because appraisal treatment varies, verify how it applies to a specific property.
Can I sell my house if the solar panels are leased?
Yes. You'll typically either have the buyer assume the lease (which usually requires them to qualify with the solar company, provide notice, and possibly pay a transfer fee) or buy out the remaining contract before closing. The key is calling the solar provider early to get the exact transfer terms and buyout figure in writing.
What is a UCC-1 filing on solar panels?
It's a financing statement that acts as a lien on solar equipment bought with a loan. It can appear in a title search and usually needs to be paid off or formally resolved at closing so title transfers clean. If your panels were financed, ask your lender or the solar company whether a UCC-1 is on file and what the current payoff is.
Does Arizona still have net metering?
Not in the old one-to-one form. APS and SRP moved to net billing, where exported energy earns a credit lower than the retail rate. APS uses the Resource Comparison Proxy (RCP) export rider with grandfathering and rate-lock windows; SRP uses separate solar price plans (APS and SRP, accessed July 2026). Confirm current terms with the utility that serves the specific address.
Which utility serves my West Valley home — APS or SRP?
It depends on the neighborhood; both operate across the West Valley. Because the solar credit rules differ between them, confirm the servicing utility for the exact address rather than assuming — your agent or the utilities can verify it.
Should I buy a home with an old roof and solar panels on it?
It can still be a good buy — just factor in that replacing a roof under panels means paying to remove and reinstall them. Ask the age of the roof and the panels, whether any warranties transfer, and who has serviced them, so there are no surprises later.
