Two houses on the same Chandler cul-de-sac, built by the same production builder in the same year with the same solar package bolted to the roof, can be paying two different companies for that power. One is billed by Arizona Public Service. The other is billed by Salt River Project. The line between them doesn't follow the street, the HOA boundary, or the zip code. It follows the address, lot by lot, and nobody drew it with a homeowner's convenience in mind.

Most Chandler sellers never think about which utility they're on until a buyer's agent asks, or until an appraiser comes back with a number that doesn't match what the listing promised. By then the answer isn't just a curiosity. It changes what the solar system is worth, who has to sign off before the sale can close, and how many weeks get added to escrow.

Chandler Doesn't Sit Cleanly on Either Side

Most cities in the Phoenix metro sit inside one utility's territory. Mesa, Tempe, and Fountain Hills run almost entirely on SRP. Glendale, Peoria, and Surprise run almost entirely on APS. Chandler is one of the few East Valley cities where the boundary actually cuts through town, block by block, with no obvious geographic logic to it. A homeowner can't guess correctly by knowing which side of the Loop 202 they live on. The only reliable way to find out is to look at the bill or check the address directly with each utility.

That split matters because APS and SRP don't just charge different retail rates. They pay a home's solar system different amounts for the power it sends back to the grid, and they got there through completely different regulatory paths.

Same City, Different Rulebook

APS is a regulated investor-owned utility. Its export rate for solar customers is set through a formula approved by the Arizona Corporation Commission, locked in at the moment a system interconnects, and stepped down on an annual public schedule for new installations. A system that connected to the APS grid back in 2017 locked a rate near 12.9 cents per kilowatt hour for the power it exports. A system interconnecting under the current APS rate rider, in effect as of this month, locks closer to 5.5 cents. Same utility, same city, a rate that's fallen by more than half depending purely on when the panels went up.

SRP runs on a different set of rules entirely. It's a public power district, not an investor-owned company, and it isn't regulated by the ACC the way APS is. Its board sets its own solar price plans, and residential export credits under those plans typically run just a few cents per kilowatt hour, well below the retail rate SRP charges for power flowing the other direction. Its board is chosen through a landowner-based voting system, and that board, rather than a state regulator, decides how solar export credits are set within SRP territory.

None of that changes what a Chandler homeowner can do about it. Service territory is fixed by geography. A homeowner on the SRP side of a Chandler street can't call APS and ask to switch, and the reverse is just as true. The rate the house gets is baked into the parcel before a buyer ever sees the listing.

Where This Actually Bites, at the Closing Table

The utility split explains why identical Chandler homes can carry different solar economics. What actually stalls a sale is a separate question: how the system is financed, and what that financing structure requires before a deed can transfer.

A solar system in Arizona generally falls into one of three buckets, and each behaves differently once a house goes under contract.

That UCC-1 filing is the detail most sellers have never heard of. Under Arizona law, a financing statement covering equipment attached to real property gets recorded in the same place a mortgage does, the county recorder's office. It sits on the title the same way a lien would, and a buyer's lender will not fund a loan until it's addressed. For an owned system, none of this exists. For a financed one, it's a document that has to be tracked down, and often the original loan paperwork is buried somewhere a homeowner hasn't looked at in years.

A leased system creates a different kind of delay. The buyer isn't just signing a mortgage. They're applying for a second approval from a solar company that runs its own credit check on its own timeline, a process that commonly takes two to six weeks and can fail without much warning if the buyer's debt-to-income ratio doesn't clear the solar company's bar, even after the mortgage lender has already signed off. A national survey of real estate agents conducted in 2025 found that 48 percent had a solar system complicate a transaction, and in nearly every case the complication traced back to a leased or financed system rather than one the seller owned outright.

The industry has started building for this. The Arizona REALTORS Solar Addendum, the form agents attach to a purchase contract whenever a property has solar, was substantially revised in November 2025 after recurring feedback about exactly these delays. The Central Arizona Association of REALTORS wrote about the update directly, noting that a financed or leased system can require the buyer to satisfy two separate decision makers on two separate timelines, and that approval by one is no guarantee of approval by the other.

What This Means Before You List or Write an Offer

None of this means solar is a liability in Chandler. Owned systems transfer cleanly and add real value. The friction shows up specifically when financing or leasing is involved, and it shows up earlier than most people expect.

A few things worth doing before a Chandler solar home goes under contract in either direction:

• Confirm in writing whether the address is served by APS or SRP. Don't assume based on the neighborhood next door.
• Pull the original solar paperwork and determine whether the system is owned, financed, or leased. If there's a loan, ask the lender whether a UCC-1 fixture filing exists and what's required to clear it.
• If it's a lease, read for an escalator clause. Some Chandler homeowners signed agreements years ago where the monthly payment increases on a fixed schedule, and a buyer assuming the lease is assuming that schedule too.
• Start the solar company's transfer or qualification process as soon as the contract is signed, not the week before closing. National lease programs advertising in Chandler right now, including Palmetto's LightReach product, list monthly payments in the neighborhood of $82 to $144 depending on system size, and a buyer needs to know that number early enough to qualify against it.
• If the system is leased and a buyer is hesitant, a seller can sometimes pay off the remaining lease balance before closing so the home conveys with owned panels instead. It's an upfront cost, but it removes an entire layer of approval from the transaction.

FAQ

Can I switch from SRP to APS, or the other way around, if I don't like my rate? No. Service territory in the Phoenix metro is fixed by geography, and neither utility competes for customers inside the other's boundary. Whichever name is on the bill is the only residential provider available at that address.

Does a fully paid-off solar system need any special paperwork at closing? Generally no. An owned system transfers with the home the same way a built-in appliance would, and its value can be reflected in the appraisal.

What's the first call to make if I'm listing a Chandler home with a solar lease? Call the solar company before the sign goes in the yard. Ask what the transfer or buyout process actually requires and how long it takes. That answer should shape the closing date on the listing agreement, not surprise everyone after an offer is already in.

Solar adds real value to a Chandler home when it's owned outright, and it adds real complexity when it isn't, and the difference between those two outcomes usually comes down to paperwork nobody thought to pull until a buyer's lender asked for it.
