Solar Panel Cost in Arkansas (2026 Estimate)

Data last updated September 10, 2026 · ranks #38 of 50 states for modeled payback

Arkansas averages about 4.5 peak sun hours a day (about average for the US) with an approximate residential electricity rate near 12¢/kWh, on the lower end nationally. In the model used here, an 8 kW system in Arkansas produces roughly 10,510 kWh a year and trims about $1,300 off annual electricity costs, paying back its net cost in about 12.0 years. That is a middle-of-the-pack payback, so whether solar is worth it in Arkansas often comes down to your specific rate, roof, and any state or utility incentives.

Estimated system cost and payback in Arkansas

Costs assume roughly $2.70/watt installed for Arkansas; the net column applies a 30% federal credit for comparison with quotes that include it. Savings and payback use the state's sun hours and rate above.

The 30% federal Residential Clean Energy Credit ended for systems paid for after December 31, 2025 under the 2025 federal budget law. Net-after-credit figures apply only if you still qualify (for example a 2025 expenditure, or a leased system where the installer passes a credit through). Confirm with a tax professional.

What moves the numbers in Arkansas

Two inputs drive most of the difference between states: how much sun a system sees and what each offset kilowatt-hour is worth. Arkansas's 4.5 sun hours set production, and its roughly 12¢/kWh rate sets what that production saves. The bigger unknowns are your roof, shading, and how your utility compensates exported power, since a lower export rate can pull real savings below the retail-rate figure above.

Net metering and export credits in Arkansas

For most of the past decade Arkansas had one of the friendlier policies in the South: full one-to-one retail net metering under Act 827 of 2019, with excess credits rolling forward month to month. Act 278 of 2023 changed that for systems interconnected after September 30, 2024, moving new customers to net billing in which exports are credited at an avoided-cost rate set through the Public Service Commission rather than the retail price. Customers who interconnected before the deadline keep their retail-rate treatment for a grandfathering period that runs into 2040.

Under the new arrangement the electricity you consume as it is produced is still worth the full retail rate, but the surplus you send back is worth only a few cents per kilowatt-hour on most utilities. Ask your utility for the specific avoided-cost figure it uses and whether it varies by season, because those numbers are filed with the Commission and updated periodically.

Arkansas solar incentives beyond the federal credit

Arkansas offers no state income tax credit, rebate or sales tax exemption for residential solar, and solar equipment is not exempt from property tax assessment. Third-party leasing and power purchase agreements have been legal since Act 464 of 2019, which opened the door to installers offering systems with little or no money down. The Arkansas Energy Office within the Department of Energy and Environment periodically administers federally funded programs, including Solar for All dollars aimed at lower-income households, so it is worth checking there for current opportunities.

A few electric cooperatives and municipal utilities run modest efficiency rebates, but none provide meaningful solar incentives. Homeowners here should build their decision around the federal tax credit, if they qualify for it, and the relatively low installed cost per watt that competitive local installers can offer.

Utilities and rate plans in Arkansas

Entergy Arkansas is by far the largest provider, serving Little Rock and much of the central and southern parts of the state. SWEPCO covers the western counties around Fayetteville and Texarkana, OG&E serves the Fort Smith area, and Liberty serves a small corner in the northwest. Roughly a third of Arkansans are members of electric cooperatives such as First Electric, Carroll Electric and Ozarks Electric, with municipal systems including Conway Corp, Jonesboro City Water and Light and North Little Rock Electric. Retail prices are among the lowest in the country, with mostly flat residential rates and seasonal summer adjustments, which lengthens solar payback compared with high-cost states even though sunshine is decent.
