Where Arkansas sits nationally

Every state by sunshine (left-to-right) and payback speed (faster toward the bottom). Arkansas is highlighted, its position shows whether sun or electricity rates drive its return.

Arkansas (highlighted): 4.8 kWh/m²/day, 17.2-yr modeled payback - slower than the national average.

What the data says about solar in Arkansas

Arkansas ranks #33 of 51 with a composite solar score of 24/100 (Marginal). The score blends inputs from NREL and EIA: average irradiance of 4.8 kWh/m²/day, residential electricity at 11.4¢/kWh, a turnkey 6 kW installed cost of $16,500 ($2.75/W), and 2 tracked state and utility incentive programs.

On those inputs, a 6 kW array here is modeled to generate roughly 8,410 kWh/year and offset about $959 in annual utility spending at the state's average rate, an estimated 17.2-year simple payback (#45 of 51 for speed to break-even) and a projected +$7,475 net position over a 25-year horizon before utility-rate escalation.

Policy matters as much as physics. Arkansas's net-metering framework is classified as full, which governs how exported generation is credited, and its renewable portfolio standard is: Mandatory (15% by 2040). The 2 active programs tracked in DSIRE include tax exemption and net metering types, each can stack to compress payback. Note that the 30% federal residential solar tax credit (§25D) ended for systems placed in service after December 31, 2025, so state and utility incentives now carry more of the economics, confirm current federal rules with the IRS and your tax advisor.

Your next step

How to act on Arkansas's numbers.

  • Run the savings calculator with your real electricity bill, the figures above use state averages, not your usage. Calculate for Arkansas
  • Check net-metering and SREC value before signing, in a "full" state, export compensation often decides the return. Net-metering guide
  • Stack Arkansas's 2 incentive programs, each lowers net cost or raises annual return. See all programs

Modeled estimates from public data, not financial advice; a binding figure requires a site-specific assessment from a licensed installer.
