Solar Energy in Kansas: What You Need to Know
Kansas has excellent solar resources in the western part of the state. The combination of good sun hours and moderate rates makes solar increasingly competitive, though wind remains the dominant renewable.
Electricity Rates in Kansas
The average residential electricity rate in Kansas is 13.5 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
Kansas averages 4.8 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 Kansas produces approximately 8,410 kWh per year, accounting for standard system efficiency losses and typical weather patterns.
Kansas Solar Incentives and Programs
No state tax credit. Net metering available for systems up to 25 kW with most utilities. Property tax exemption for renewable energy systems. No sales tax exemption specific to solar.
Incentive Summary for Kansas
- Federal Tax Credit: 30% ITC (available through 2032)
- State Tax Credit: None
- Net Metering: Available
- SRECs: Not available
