Solar calculator for Kansas

The average Kansas home uses 876 kWh a month and pays 14.2 cents per kWh, which puts Kansas at mid-range electricity prices, so payback depends mostly on how much sun your roof gets. Kansas has both a heating and a cooling season, so the bill swings both ways and a full year of bills gives a better answer than one month. A south-facing fixed array there makes about 1,526 kWh per installed kW a year, and the worst winter month still gets 3.31 peak sun hours a day. Drop in your own bill below and the numbers on this page are replaced by yours.

A worked example for Kansas

Take the average home: 876 kWh a month, which is 10,512 kWh a year, at 14.2 cents per kWh (EIA, 2024 residential averages, as of 2026-11). Sized to cover all of that use, the tool returns 6.9 kWdc and 17 panels, needing about 357 square feet of roof. The installed estimate is $17,153 (national median, EnergySage H2 2025), yearly savings are about $1,493, and simple payback is 11.5 years, with no incentive applied.

Sun and yield in Kansas

We use 1,526 kWh per installed kW per year for Kansas, from NREL PVWatts v8 for the state's largest city at a 20 degree south-facing tilt (via TheGreenWatt, as of 2026-11). The darkest month averages 3.31 peak sun hours a day, which matters if you plan to go off-grid or size a battery. A different roof angle or heavy shade changes this, so treat it as a starting point.

Incentives

The 30% federal tax credit ended for homeowner purchases after December 31, 2025, so none is applied here. See the tax credit guide. Look up Kansas and your own utility for net metering terms and any local programs before relying on a payback number.
