Quick answer
Arkansas solar economics depend on your roof, utility and quote. This page uses illustrative assumptions of 5 peak sun hours, $2.75/W and 11.0 cents/kWh; these are not verified current market averages or account rates.
Notes updated 2026-07-24
- Best for
- Arkansas homeowners comparing solar costs, incentives, and payback assumptions.
- Inputs needed
- annual kWh usage, utility rate, installed $/W, net-metering policy
- Formula used
- Planning production = system kW x peak sun hours x 365 x (1 - 14.08% losses). Retail-value ceiling = production x assumed retail price; actual export value can be lower.
- Method references
- state incentive data, utility tariff checks, Wattcrunch price benchmarks
Key fact about Arkansas solar
Arkansas has solid sun hours (5.0/day) and full retail net metering, but low electricity rates extend payback. Arkansas is an underserved solar market - fewer installers means shopping quotes is especially important.

Illustrative 8 kW system in Arkansas
Annual production
12,544 kWh
Retail-value ceiling, not savings
$1,380
System cost (est.)
$22,000
Includes 14.08% planning losses. Valuing all production at retail is a ceiling, not a net-billing savings estimate; actual self-use, export rates and ownership costs change the result. No new Section 25D homeowner credit in 2026.
Worked example
Arkansas: a transparent 8 kW planning example
This example shows how the published Arkansas assumptions flow through a simple first-pass calculation.
Example household usage
10,800 kWh/year
Estimated production
12,544 kWh/year
Rate used in the example
11.0 cents/kWh
Retail-value ceiling, not bill savings
$1,380/year before ownership costs
Arkansas Net Metering Policy
Full retail net metering (APSC Rule)
Arkansas requires full retail net metering under APSC rules. Entergy Arkansas and AEP Southwestern Electric must credit exports at retail. Monthly net excess carries forward for 12 months.
Arkansas Solar Incentives
Programs require eligibility checks and cannot always be combined. Federal 25D credit is $0 for new homeowner-owned systems in 2026.
- ✓Sales tax exemption on solar equipment
- ✓Property tax exemption
- ✓AECC and co-op rebate programs (varies)

State-specific decision guide
What to verify before signing a Arkansas solar quote
In Arkansas, the financial result depends on more than sunshine or the headline installation price. Confirm the export rule, program eligibility date, and interconnection timeline for your exact utility before treating a payback estimate as a promise.
Export value
This page models full retail net metering (apsc rule). Ask which tariff and export credit apply to your account, not only which program name appears in the proposal.
Incentive eligibility
Check equipment, income, installer, application, and placed-in-service rules before subtracting an incentive from the quote. Programs can close or change terms.
Interconnection
Budget for the published 4–8 weeks and confirm who pays for a required meter, service upgrade, or engineering review.
Source trail: production assumptions use NREL PVWatts; incentive discovery should be checked against DSIRE; electricity-market context is available from the EIA. Confirm final tax treatment with the IRS and your utility.
