Solar Panels in Arkansas: Cost, Payback & ROI (2026)
Is solar still worth it in Arkansas after the 30% federal tax credit expired? These pre-computed estimates use NREL PVWatts production data and current 11.8¢/kWh Arkansas electricity rates for a typical home using 900 kWh/month.
Section 25D (30% federal solar tax credit) expired December 31, 2025
All numbers below reflect 2026 math with no federal residential credit. State incentives, where applicable, are noted in the section below.

Is Solar Worth It in Arkansas in 2026?
Arkansas' 11.8¢/kWh electricity rate makes solar economics challenging. The state restored retail-rate net metering in 2019 after a brief reduction, which improved the solar outlook. Entergy Arkansas and SWEPCO serve most of the state.
For a typical Arkansas home consuming 900 kWh per month, our calculation shows a 7.6 kW system needed for 100% offset. At the current national average installed cost of $2.95/W (LBNL Tracking the Sun 2024), that's $22,437 gross before any state rebates. Year-one savings of $1,274 grow each year as electricity rates escalate — the model assumes 2.5%/year (EIA AEO 2024).
The 15.2 years payback period is longer than the national average due to low electricity rates or limited solar resource. Over 25 years — the standard warranty period for most premium panels — a Arkansas homeowner following this profile would save an estimated $40,754 total, for a net benefit of $18,318 after recovering the system cost.
