Solar Energy in Arkansas: What You Need to Know
Arkansas has moderate solar potential with decent sun hours. Low electricity rates make payback periods longer than sunbelt states. Net metering is available and the solar market is growing steadily.
Electricity Rates in Arkansas
The average residential electricity rate in Arkansas is 11.5 cents per kWh, which is below the national average of approximately 16 cents per kWh. Lower electricity rates mean the payback period is longer, but the 25-year savings are still substantial. As electricity rates continue to rise (averaging 3% per year nationally), the value of solar ownership increases over time.
Peak Sun Hours and Solar Production
Arkansas averages 4.6 peak sun hours per day, which is a solid level for residential solar. While not the sunniest state, the combination of decent sun hours with modern high-efficiency panels produces meaningful electricity savings throughout the year. A 6 kW system in Arkansas produces approximately 8,059 kWh per year, accounting for standard system efficiency losses and typical weather patterns.
Arkansas Solar Incentives and Programs
No state solar tax credit. Net metering available up to 25 kW for residential. Entergy Arkansas and other utilities offer interconnection. Property tax exemption for solar systems.
