Solar in Arkansas costs about $2.56 per watt, so the typical 8.16 kW system runs about $20,890 before incentives. The panels are among the lowest-priced in the country, but so is the 13.57¢ grid power they replace, so payback is slow and depends on how much of the power you use at home.

Cheap on both sides of the meter: the Arkansas solar trade-off
Arkansas is cheap on both sides of the meter, and that cuts both ways. Cheap hardware helps your payback. Cheap grid power is its stubborn competitor, because every kWh your roof makes replaces power that did not cost much to begin with.
What the panels cost
Tied for the 2nd-lowest installed price of 51. The hardware is a genuinely good deal.
What the panels compete with
The statewide average residential rate, well below the national average.
The real question in ArkansasIt is not whether the hardware is a good deal. It is whether replacing 13.57¢ power fast enough justifies the price.
Against 13.57¢ power, Arkansas solar wins slowly
Power you use yourself offsets the retail rate your utility charges, 13.57¢ on average statewide. Power a new system sends out earns far less: 3.34¢ per kWh at Entergy Arkansas. So how long the typical 8.16 kW system takes to pay for itself depends on how much of its 11,351 kWh a year you use at home as it is made. Our Arkansas worth-it guide shows the math: about 22.7 years for a new Entergy Arkansas system and 23.5 years as our state figure, both simple payback before incentives.
Two forces work in your favor over time. Arkansas rates have climbed a brisk 4.68% a year over five years, faster than most cheap-power states. And heavy usage means a lot of production stays home if you shift daytime load on purpose.
13.57¢ is not your rateThe statewide average is ranking context, not a rate anyone pays. Entergy Arkansas, SWEPCO and each cooperative file their own residential rates, so rerun the numbers with the rate on your own bill.
What $2.56 a watt buys in Arkansas, size by size
The typical Arkansas system is 8.16 kW at about $20,890 gross. Too few Arkansas installs exist to measure a local median, so that size is modeled from neighboring states. Each row shows the gross price. For the picture beyond Arkansas, start with our solar panel costs nationwide.

Three Arkansas export deals, set by when your paperwork was filed
Under Act 278 of 2023, how your solar is valued depends on your interconnection date, or on whether you own the system at all.
Legacy net metering, grandfathered under Act 278. The old math still applies. Protect that status before you modify anything.
Act 278 of 2023Imports at retail. ALL exports at an avoided-cost rate redetermined each year from trailing wholesale market prices. Self-use carries the case.
Solar leasing is explicitly allowed in Arkansas; residential PPAs are not. It is the one path that can still carry the federal 48E credit, through a third-party owner.
DSIRE, May 2026The middle card governs most readers. Entergy Arkansas, which serves about 42% of homes, credits new exports at 3.34¢ per kWh on bills from March 2026 to February 2027, and leftover credit rolls to the next bill with no year-end payout or expiry. SWEPCO credits 3.656¢ for the same months. Other utilities set their own rate, so ask yours for the current number in writing.
Distrust a fixed export valueExport rates reset every year. Treat any proposal that quotes a fixed export value with suspicion.
Five ways to buy well at Arkansas prices
Cheap power makes the payback slow. These steps keep it from getting slower:
- Hold every bid to $2.56 per watt. At tied 2nd-lowest pricing there is no excuse for a $3.20 quote on an ordinary roof.
- Size at or below your yearly usage. Overproduction sells at wholesale-class rates.
- Shift daytime load. Pool pumps, laundry and pre-cooling in daylight raise the share you use yourself.
- Compare an ownership quote with a lease. Leasing is explicitly legal here, and a third-party owner can still use the federal 48E business credit. The 30% homeowner credit (25D) ended after December 31, 2025.
- Ask a co-op or city utility about its own terms. Arkansas co-ops set their own, so check separately if one serves you instead of an investor-owned utility.
When the Arkansas math says no
Some households cannot beat 13.57¢ power. Think twice if one of these fits:
- Light users on small bills. The average Arkansas bill already sits low. A $90-bill household has too little to offset for an 8 kW ticket.
- Export-heavy homes with no load to shift. Wholesale-indexed exports cannot carry a payback on their own.
- A proposal built on the old net metering. If it shows retail-valued exports and your paperwork is dated 2026, it models a program that closed to you in September 2024.
- Short-horizon owners. Payback here takes many years, so it needs staying power, or a sale that prices the system in.

Frequently asked questions
How much do solar panels cost in Arkansas in 2026?
About $2.56 per watt installed, tied for the 2nd-lowest price of 51, per the EcoGen Solar Cost Index (September 2026 Edition). The typical 8.16 kW system, modeled from neighboring states, runs about $20,900 before incentives.
Does Arkansas still have net metering?
Only for grandfathered systems whose interconnection paperwork was filed before September 30, 2024. Under Act 278 of 2023, new customers buy imports at retail and get a bill credit for all exports at an avoided-cost rate redetermined each year from wholesale market prices. Leftover credit rolls to the next bill, with no year-end payout or expiry.
What is the solar payback period in Arkansas?
Our state figure is about 23.5 years, simple payback before incentives, weighted by customers across Entergy Arkansas, Oklahoma Gas and Electric and SWEPCO, which run from 22.7 to 26.6 years. A new Entergy Arkansas system takes about 22.7 years, with exports credited at 3.34¢ per kWh. Your own number depends on when your paperwork was filed, your utility’s rate and export credit, and how much of your solar power you use at home. Our Arkansas worth-it guide shows the math, which leaves out upkeep and price rises.
Can I lease solar panels in Arkansas?
Yes. Solar leasing is explicitly allowed in Arkansas even though residential PPAs are restricted, and a lease is now the main route to federal credit value, since the third-party owner can claim the federal 48E business credit, while the 30% homeowner credit (25D) ended after December 31, 2025.
I already have solar in Arkansas. Did the rules change for me?
If your interconnection paperwork was filed before September 30, 2024, you keep 1-to-1 retail net metering under the grandfather provision. Confirm with your utility in writing before modifying or expanding the system, since changes can affect legacy status.
How we calculate these costs
Cost figures use Arkansas’s entry in the EcoGen Solar Cost Index (September 2026 Edition), $2.56 per watt as of September 25, 2026. The 8.16 kW typical size is modeled from neighboring states, because too few Arkansas installs exist to measure a local median. Paybacks come from our per-utility file of October 30, 2026: simple payback before incentives, with no upkeep or price rises. Your own figure depends on your paperwork date, your utility’s export credit and how much power you use at home. The Arkansas worth-it guide works through the math. Export rates reset each year and are stated as structure only.
