Solar Panel Cost in Kansas (2026 Estimate)

ByIndependent solar research and calculators

Data last updated · ranks #21 of 50 states for modeled payback

Kansas averages about 5.0 peak sun hours a day (about average for the US) with an approximate residential electricity rate near 14¢/kWh, on the lower end nationally. In the model used here, an 8 kW system in Kansas produces roughly 11,680 kWh a year and trims about $1,600 off annual electricity costs, paying back its net cost in about 10.3 years. That is a middle-of-the-pack payback, so whether solar is worth it in Kansas often comes down to your specific rate, roof, and any state or utility incentives.

Estimated system cost and payback in Kansas

Costs assume roughly $3.00/watt installed for Kansas; the net column applies a 30% federal credit for comparison with quotes that include it. Savings and payback use the state's sun hours and rate above.

Modeled solar cost, production, savings and payback in Kansas by system size
System size Gross cost Net after 30% credit Yearly production Yearly savings Payback
6 kW $18,000 $12,600 8,760 kWh $1,200 10.3 yrs
8 kW $24,000 $16,800 11,680 kWh $1,600 10.3 yrs
10 kW $30,000 $21,000 14,600 kWh $2,000 10.3 yrs

The 30% federal Residential Clean Energy Credit ended for systems paid for after December 31, 2025 under the 2025 federal budget law. Net-after-credit figures apply only if you still qualify (for example a 2025 expenditure, or a leased system where the installer passes a credit through). Confirm with a tax professional.

What moves the numbers in Kansas

Two inputs drive most of the difference between states: how much sun a system sees and what each offset kilowatt-hour is worth. Kansas's 5.0 sun hours set production, and its roughly 14¢/kWh rate sets what that production saves. The bigger unknowns are your roof, shading, and how your utility compensates exported power, since a lower export rate can pull real savings below the retail-rate figure above.

Net metering and export credits in Kansas

Kansas law requires investor-owned utilities to offer net metering to residential systems up to 15 kilowatts, and Evergy credits excess generation in kilowatt-hours that carry forward from month to month. At the end of the annual cycle any remaining surplus is compensated at a rate tied to the utility's system average cost rather than retail, so the value of large overproduction is limited. A 2014 amendment let utilities place customers with self-generation into a separate rate class, which set up years of dispute over what those customers should pay.

Evergy, then operating as Westar and KCP&L, won approval in 2018 for a demand charge on residential solar customers, but the Kansas Supreme Court struck it down in 2020 as discriminatory pricing, and the Kansas Corporation Commission has since revisited how distributed generation customers are billed. Homeowners considering solar should read the current DG rate schedule closely, because the terms have shifted more than once. Cooperatives and municipal utilities, which serve a large share of rural Kansas, set their own policies and often pay avoided cost for exports.

Kansas solar incentives beyond the federal credit

Kansas has no state solar tax credit, no rebate program and no renewable energy credit market for homeowners. The main state benefit is a property tax exemption: a residential solar system installed after 2016 is exempt from property tax for ten years following installation, which keeps a rooftop array from raising your assessment during most of its payback period.

Solar equipment is subject to Kansas sales tax, and there are no state-backed loan programs specific to residential solar as of 2026, though rural customers may qualify for USDA programs on agricultural properties. Strong sunshine across much of the state and relatively low install costs help, but without state money the economics rest on the federal credit and the utility's net metering terms.

Utilities and rate plans in Kansas

Evergy, formed from the merger of Westar Energy and Kansas City Power and Light, serves the majority of Kansans through its Kansas Central and Kansas Metro divisions, covering Wichita, Topeka and the Kansas side of the Kansas City area. Liberty (formerly Empire District Electric) serves a corner of the southeast, and dozens of cooperatives and municipal utilities such as Midwest Energy and the Kansas City Board of Public Utilities cover the rest. Evergy offers optional time-of-use plans and carries a larger fixed customer charge than many utilities, which erodes savings from smaller systems. The rate-class history at the KCC means solar customers should compare the DG tariff with the standard residential rate before assuming retail-value offsets.
