Arkansas solar calculator
Size a Arkansas home solar system from your electric bill — kW, panel count, roof area, true cost with no federal credit for 2026 installs, and payback.
Quick answer: At $0.144/kWh and 4.5 peak sun hours, a $200/month bill needs about 13.53 kW — 33 × 410 W panels covering ~66 m². Gross cost is ~$32,337 with no federal credit for systems installed after 2025, offsetting $2,400 a year for a ~13.5 year payback.
Your details
Ballpark, not gospel. Sized at 78% real-world output with the Arkansas sun-hour average — confirm shading, roof angle and your utility's net-billing terms with a local installer before buying. The calculator values all generation at your retail rate; exports earn far less (about 2.5¢/kWh under Act 278 net billing), so real savings track self-consumption and batteries.
The 30% credit ended — what changed
The residential clean energy credit (26 U.S.C. § 25D) gave homeowners a 30% credit on solar installed from 2022 through 2025. The July 2025 tax law ended it: no credit is available for property placed in service after December 31, 2025. That is why every figure on this page is ~30% higher than pre-2026 guides show. If your system went live by the end of 2025, tick the box above to see the credit applied; leased systems may still benefit because the leasing company claims the commercial credit.

Solar in Arkansas: the details
Solar cost in Arkansas
Solar is cheap to install in Arkansas. The EnergySage marketplace averaged about $2.39 per watt installed in 2026, with market quotes typically landing $2.03–$2.75/W — below the $2.50–$3.50/W national band. A typical ~14 kW system grosses around $33,500, with no federal credit for 2026 homeowner installs.
What moves the number: roof complexity and panel tier. Arkansas's low electricity rates mean you need a bigger system to cover the same bill — which is exactly why the $200 example below needs a 13.53 kW array.
Export rules: getting paid for surplus power
Arkansas ended 1:1 retail net metering for new systems. Act 278 (2023) moved new systems to net-billing credits at avoided cost — about 2.5¢/kWh — roughly one-sixth of the retail rate.
The key exception: systems installed by September 30, 2024 are grandfathered in retail-rate net metering for 20 years. If you're buying a house with existing solar, confirm the grandfathered status — it changes the economics completely.
Practical takeaway: for new Arkansas systems, exports are nearly worthless. Self-consumption (and a battery for evening load) is the whole game.
Arkansas solar incentives
No major statewide solar incentive was found in 2026 sources — Arkansas offers no state sales or property tax exemption for solar, and no state credit or rebate.
Is solar worth it in Arkansas?
Verdict: marginal for new systems. Act 278's avoided-cost net billing (~2.5¢/kWh) means exports are nearly worthless; the ~13.5-year payback assumes you self-consume most of what you generate. If your system went in before the September 30, 2024 grandfathering cutoff, you're on 1:1 net metering for 20 years and the math is much better.
Questions people actually ask
Straight answers, no fluff. Then run your own numbers above.
How many solar panels do I need in Arkansas?
It follows your bill. At the Arkansas average of $0.144/kWh and 4.5 peak sun hours, a $200/month bill needs about a 13.53 kW system — roughly 33 × 410 W panels covering ~66 m² of roof.
What is the average cost of solar panels in Arkansas in 2026?
The EnergySage marketplace averaged about $2.39 per watt installed in 2026, with market quotes typically $2.03–$2.75/W — below the national $2.50–$3.50/W band. A typical ~14 kW system grosses around $33,500, with no federal credit for 2026 homeowner installs.
Did Arkansas end net metering?
For new systems, yes. Act 278 (2023) ended 1:1 retail net metering; new systems earn net-billing credits at avoided cost, about 2.5¢/kWh. Systems installed by September 30, 2024 are grandfathered in retail-rate net metering for 20 years.
Does Arkansas offer any solar tax credit or rebate?
No major statewide solar incentive was found in 2026 sources — Arkansas offers no state sales or property tax exemption for solar, and no state credit or rebate.
Is the 30% federal solar tax credit still available?
Not for homeowner purchases anymore. The residential clean energy credit (26 U.S.C. § 25D) is not available for property placed in service after December 31, 2025, under the July 2025 tax law (Public Law 119-21). Systems installed by the end of 2025 can still claim 30%, and leased systems may still benefit because the leasing company claims the commercial credit instead.
