Buying a House with Solar in Arkansas: What to Check Before You Close

Buying a house in Arkansas is already a lot to keep track of. When the listing photos show solar panels on the roof, most buyers do not know how to factor that in. Is the system an asset, a problem, or just a neutral piece of the property? The honest answer is that it depends on the specific system, the paperwork, and the condition of the equipment. None of that shows up on the MLS listing, and most of it will not show up in a standard home inspection either.

This guide walks through what to look at before you sign, why a regular home inspector usually cannot answer the solar-specific questions, and how a pre-purchase solar inspection fits into a normal option period.

Why a General Home Inspector Is Not Enough

Home inspectors do important work, but they are not solar technicians. Most of them will note that a system is present, glance at the disconnect, and move on. They are not going to climb the array, open the inverter cover, log into the monitoring portal, or compare what is installed against what the original contract said was being installed. That is not a criticism of the trade. It is just outside the scope of a typical residential inspection.

The problem is that the issues that actually matter on a solar home are mostly in the parts a general inspector skips. Wiring on the roof, conduit support in the attic, breaker placement in the main panel, monitoring portal access, and the gap between the listed equipment and the panels that are actually up there. None of that gets flagged in a standard report. If something is wrong, the buyer often does not find out until the system stops producing or an electrician opens the panel a year later.

The Seven Things Worth Checking

A thorough pre-purchase look at a residential solar system covers seven main areas. You can run through these with any qualified solar contractor, and they are useful even if you decide not to hire anyone. The point is to know what to ask and what to look for.

• Solar panels and array layout. Are the panel brand, model, and count on the roof actually what the seller's paperwork describes? Are there visible cracks, hot spots, delamination, or unusual soiling? Is the layout reasonable for the roof, or are panels squeezed into shaded corners where they will not produce?
• Roof mounting and structural integrity. Is the racking attached cleanly? Are the roof penetrations flashed and sealed? Are there signs of water intrusion in the attic underneath the array? Mounting issues are expensive to fix because the panels usually have to come off.
• Inverter and power electronics. Is the inverter the same brand and model as the paperwork says? Are there fault codes on the display? Does the AC disconnect operate cleanly? If the system uses optimizers or microinverters, are the status lights normal?
• Wiring and conduit. Is the conduit supported properly in the attic? Is there exposed wiring on the roof that should be in conduit or clipped down? Loose wiring is one of the most common findings on Arkansas inspections, and it is rarely something a homeowner can see from the ground.
• Electrical panels, disconnects, and labeling. Is the PV disconnect labeled with operating voltage and current? Are the rapid-shutdown placards in place? Is the backfeed breaker sized and located correctly for the main panel bus? This category is where most code-compliance issues live.
• Meter, ground equipment, and interconnection. Is the production meter present and working? Is the bidirectional utility meter installed? Is the outdoor conduit between the meter and disconnect in good shape, or has it been baking in the sun for ten years?
• Monitoring and production history. Can the seller (or you) actually log into the monitoring portal? Is the system online and reporting? Does the lifetime production roughly match what a system of this size should have generated in Arkansas?

You do not need to be a solar professional to keep this list in mind during a showing. Take photos of the array, the inverter label, and the electrical panel. Those photos alone give a qualified inspector enough to start with later.

Owned, Leased, or Financed: The Ownership Question That Surprises Buyers

One of the most important questions has nothing to do with the equipment itself. It is whether the seller actually owns the system. Solar on a residential roof in Arkansas typically falls into one of three categories.

• Owned outright. The seller paid for the system in cash or has paid off the loan. The system transfers with the house and there is no monthly payment to assume. This is the cleanest scenario.
• Financed with a loan. The seller still owes money on a solar loan. In most cases the seller pays off the loan at closing, but you want that confirmed in writing. Some solar loans have UCC filings against the equipment that need to be cleared.
• Leased or under a power purchase agreement. The seller does not own the system. A third-party company owns it and either leases it to the homeowner or sells them the power it produces. To take possession of the house, you usually have to either assume the lease or have the seller buy it out. Lease assumption involves a credit check and contract review with the leasing company, and the monthly payment may or may not be less than the electric bill savings.

The reason this matters is that lease and PPA agreements run for 15 to 25 years and include escalator clauses, transfer fees, and buyout schedules that are not always favorable to a new homeowner. Ask for a copy of the original contract early in the process. Read it before the option period closes, not after.

Monitoring Access and Production History

If a solar system has been on a roof for five or six years and the seller cannot log into the monitoring portal, that is a yellow flag. It usually means one of two things: either the system has been silently underperforming and nobody noticed, or the seller never set up monitoring access in the first place. Both situations are fixable, but you want to know before closing.

Ask the seller for the monitoring portal login (SolarEdge, Enphase, SMA, and Tesla are the most common in Arkansas) and check a few things. Is the system reporting today? Does the production graph look steady year over year, or has output dropped off a cliff at some point? Does the lifetime kWh number look reasonable for the system size and the years it has been installed? A roughly sized system in central Arkansas should generate somewhere around 1,200 to 1,400 kWh per year for every kilowatt of installed capacity, give or take based on shading and orientation.

Also ask whether the original installer is still in business. Several Arkansas installers from the 2018 to 2022 boom have closed or rebranded, which complicates warranty claims. It is not a deal-breaker, but it changes who you will call when something fails. An independent service provider can usually pick up where the original installer left off.

The Code-Compliance Issues That Come Up Most Often

You do not need to memorize the National Electrical Code to buy a house with solar on it, but a few items come up so often that it is worth knowing the plain-English version.

The first is the 120 percent bus-bar rule. The main electrical panel has a maximum amount of current that can be pushed onto its bus bar. When solar is connected, that adds to whatever the utility is supplying, and the total has to stay within limits. In practice, this means the location and size of the solar breaker matter. A backfeed breaker in the wrong slot, or a panel that is too small for the size of the system, can put the installation out of compliance. It is a common finding and it usually has a reasonable fix, but it should not be ignored.

The second is labeling. Solar systems are supposed to have a stack of labels: the red PV disconnect with operating voltage and current filled in, rapid-shutdown placards near the main service, and clear markings on the junction boxes. On a surprising number of homes those fields are left blank, missing, or sun-bleached past the point of readability. Labels are cheap to add but legally required, and a first responder showing up to an emergency needs them.

The third is wiring support. Conduit in the attic is supposed to be strapped to framing at regular intervals, and wiring on the roof is supposed to be clipped down with UV-rated hardware. Unsupported runs hang in space, rub on framing, and become a target for rodents. It is one of the most common findings on Arkansas inspections because the work happens up high where nobody looks.

None of these issues mean the house is a bad purchase. They are all fixable. The point of finding them before closing is that the seller, not the buyer, gets to handle the repair or the credit.

The Roof Underneath the Array

Solar panels last 25 years or more. Asphalt shingles in Arkansas usually do not. If the array was installed on a roof that already had five or ten years of wear on it, the shingles underneath the panels are going to need replacement well before the panels do. And replacing the roof means paying to remove and reinstall the array, which is typically a few thousand dollars on top of the roof work itself.

Look at the shingles around the array, not just under it. If the rest of the roof shows curling, granule loss, or visible aging, plan on a roof project sometime during your ownership. That cost is not a reason to skip the house, but it is a number to have in mind when you are negotiating. Ask the seller when the roof was last replaced and whether any of that work happened before or after the solar install.

How a Pre-Purchase Inspection Fits Into a Normal Option Period

The Arkansas residential option period is usually a week to ten days. That is enough time to run a general home inspection, schedule a separate solar inspection, and have results back in time to negotiate or walk away. The key is to start as soon as the contract is signed, not three days in.

A pre-purchase solar inspection usually involves a site visit to look at the array, the inverter, and the electrical work, a check of the monitoring portal, and a written PDF report you can hand to your agent, your lender, or the seller. The report should rate each section as good, fair, or concern, with photos for each item. That kind of documentation is much more useful in a negotiation than a verbal "looks fine to me" from a friend who has solar on their own house.

If the inspection turns up real service items, those can either become seller-paid repairs before closing or seller credits at closing. If the system is in good shape, you close with confidence and a baseline document for the years ahead. Either way, you spent a small amount of money to avoid a much larger surprise. And if you want help with repairs or upgrades after closing, the Service Division handles that for systems installed by anyone, not just Delta Solar customers.

If you are under contract on an Arkansas home with solar and the option period is ticking, do not guess. Get an independent set of eyes on the system while you still have time to do something about what they find. We can usually be on site within a few business days and have the written report back before your option period ends.
