A 9 kW home solar system in Kansas costs about $24,500 installed in 2026 (EnergySage’s Kansas average is $2.72 per watt) and saves roughly $1,670 in its first year in our base case. That gives a simple payback near 13 years and about $25,600 in 25-year net savings, with no federal credit included. The 30% homeowner credit ended for systems installed after December 31, 2025, and Kansas has no state solar tax credit.
Key takeaways
Cost: about $2.72/W in Kansas (EnergySage, July 2026), or roughly $24,500 for 9 kW.
Payback: about 13 years in the base case; 11–16 years across the price and net-metering range shown below.
Incentives: no federal or state credit for owned systems installed in 2026; a 10-year property-tax exemption applies to new claims.
Net metering: monthly surplus is credited at the utility’s system average cost of energy, not the retail rate, so size to your own usage.
Reality check: EnergySage’s own Kansas estimate of 25-year savings is lower than our base case. Use the range, not a single number.
Kansas residents paid an average of 14.56¢/kWh for residential electricity in 2025, with an average monthly bill of about $128 at 880 kWh, according to a Kansas Corporation Commission (KCC) presentation of EIA data. That is cheaper than the national average, which lengthens solar payback compared with high-rate states. This guide shows every input so you can swap in your own bill. The full model is on our methodology page, and state data is on the Kansas solar page.
💰 System Cost
What Do Solar Panels Cost in Kansas, and What Do They Save?
A 9 kW system at the Kansas average of $2.72 per watt costs about $24,480 and produces roughly 13,470 kWh a year. At 14.56¢/kWh, with 85% of that output valued at the average rate, it saves about $1,670 in year one.
Evergy serves most of eastern and central Kansas, including Wichita, Topeka and the Kansas City suburbs. To find your effective rate, divide your total bill, including fixed charges and riders, by the kWh you used. Rates are trending up: the Kansas Reflector reported Evergy Kansas residential rate increases of 3.6% in 2023 and 5.9% in 2025, plus a settlement filed at the KCC proposing a further 9.6% base-rate increase.

Cumulative cash position for a 9 kW Kansas system, no federal credit. Breakeven comes at 11.9, 13.4 and 14.6 years for $2.40, $2.72 and $3.00 per watt. Assumes 14.56¢/kWh, a 2% yearly rate rise, 0.5% yearly degradation and 85% of output credited. Source: KCC/EIA-861 2025, EnergySage 2026.
Chart summary: The three lines cross zero at about 11.9 years ($2.40/W), 13.4 years ($2.72/W) and 14.6 years ($3.00/W). After 25 years the modeled net position is roughly $28,400, $25,600 and $23,000, respectively. A $0.30 difference per watt moves payback by about a year and a half, so quote comparison matters.

Simple payback in years by installed price and net-metering credit share. Results range from 10.8 to 16.3 years for a 9 kW Kansas system at 14.56¢/kWh with a 2% yearly rate rise and no federal credit. Source: KCC/EIA-861 2025, EnergySage 2026, Kansas Corporation Commission net-metering rules.
Chart summary: Payback runs from 10.8 years (best case: $2.40/W, 95% credited) to 16.3 years (worst case: $3.00/W, 75% credited). At the Kansas average price, moving from 75% to 95% credited shortens payback from 15.0 to 12.1 years. Rate growth matters too: with flat rates (0% per year) payback in the base case stretches to about 15.2 years and 25-year net savings fall to about $14,800; with 4% per year it shortens to about 12.1 years.
How this compares with other estimates: EnergySage’s Kansas page estimates average 25-year savings of about $19,900 for a 12.05 kW system costing about $32,800. Our model is more optimistic because it uses a higher production assumption and a 2% yearly rate rise.

🏛️ Incentives
Which Solar Incentives Are Left for Kansas Homeowners in 2026?
For a home system you own and install in 2026, there is no federal or state solar tax credit in Kansas. What remains is a limited property-tax exemption and net metering.
Incentive
Status for a 2026 install
Federal §25D credit (30%)
Ended for expenditures after Dec 31, 2025; the IRS treats the expense as made when installation is complete
Kansas state solar tax credit
None
Property-tax exemption for solar (K.S.A. 79-201)
Available; for exemption applications filed after 2016 it lasts 10 taxable years after the year of installation; file with your county appraiser
Kansas sales-tax exemption
None reported by the sources we checked
Net metering (Evergy, Liberty)
Available; see the net-metering section for credit rules
Lease / PPA (§48E, installer-claimed)
Possible only if the project began construction by Jul 4, 2026 or is placed in service by Dec 31, 2027; savings reach you only if the installer passes them on
Farms and businesses
§48E under the same deadlines; USDA REAP grants have been subject to delays and policy changes, so confirm current availability
Sources: IRS FAQ on OBBB energy-credit terminations; Kansas Corporation Commission; EnergyBot summary of K.S.A. 79-201; Solar Power World; Electrek. This is not tax advice; confirm with a tax professional. Check DSIRE for utility programs.
Until December 31, 2025, Kansas homeowners could claim 30% under §25D. The One Big Beautiful Bill Act (Public Law 119-21, signed July 4, 2025) ended it for later expenditures. On the same $24,480 system, the credit would have cut the net cost to about $17,100 and payback to roughly 9.6 years in our model. It also covered home batteries, and that no longer applies to homeowner-owned systems installed in 2026. See our federal solar tax credit guide for the timeline.
Leases and PPAs: A third-party owner may still claim the commercial §48E credit if the project began construction by July 4, 2026 or is placed in service by December 31, 2027, and may pass some of it on through a lower price. Because the July 4, 2026 date has passed, a lease or PPA signed now generally has to be in service by the end of 2027 unless the installer already safe-harbored the project. Only credits the installer actually receives can be passed along. Compare the price per kWh and the annual escalator with your 14.56¢ average rate using the lease vs. buy calculator.
Agricultural properties: Kansas farms and rural small businesses can look at USDA REAP and §48E, but USDA has delayed application windows and said it would disincentivize solar on productive farmland. Confirm current rules with USDA Rural Development before planning around a grant. The agricultural solar calculator models farm systems.
⚖️ Policy & Net Metering
How Does Net Metering Work in Kansas?
Kansas law requires investor-owned utilities, including Evergy and Liberty Utilities, to offer net metering. Your solar output offsets your usage in the billing period, and leftover surplus is credited at the utility’s monthly system average cost of energy, not the retail rate.
Key points from the KCC and the Kansas Legislature’s bill summary:
Monthly surplus is not paid at retail. For systems that began operating after July 1, 2014, net excess generation is credited at 100% of the utility’s monthly system average cost of energy per kWh. Systems that began operating earlier were credited one-to-one. From January 1, 2030, all customers move to the average-cost credit.
Time-of-use rates. For customers who start on or after July 1, 2024 and are on a time-of-use rate, excess exported in a time period is credited at no less than that average cost, and any net credit carries to the next billing period.
Export-capacity limit from 2026. The KCC says capacity for customers who participate on or after January 1, 2026 is limited to 50 percent of export capacity. The bill summary describes this as generating capacity exceeding export capacity by no more than 50%, with an export-limiting device in some designs. Ask your installer how it applies to your system.
Fixed charges stay. Customer charges do not go away with solar, which is one reason we credit only 85% of output at the average rate. An Evergy Kansas Metro tariff snapshot lists a $15.25 monthly customer charge, so check your own tariff.
Co-ops and municipal utilities differ. Electric cooperatives and municipal providers are not required to offer net metering, though some do. Get the tariff in writing before you sign.
Practically, size close to what you use rather than far above it, because surplus earns less than offset usage. The solar net metering calculator models export terms.
⚡ System Size
How Should You Size Solar for a Kansas Home and Roof?
In our model, each installed kW produces about 1,500 kWh a year (5.0 sun hours × 365 × 0.82). Divide your annual usage by 1,500 to get your system size. A home using 13,500 kWh a year needs about 9 kW, or 22–23 × 400 W panels.
We use 5.0 peak sun hours as a conservative planning value. Third-party summaries of NREL PVWatts data for Wichita are higher, around 5.4 hours a day, and the real figure depends on your city, tilt and shading. Run PVWatts for your address.
Orientation and tilt: A south-facing roof at roughly 30–35° captures close to maximum output at Kansas latitudes. East- or west-facing roofs produce less, which lengthens payback. West-facing panels can still work well if your usage peaks in the late afternoon.
Shading: On a string inverter, one shaded panel can drag down its whole string. Microinverters or DC optimizers limit the loss to the shaded panels at added cost. Ask for a shade analysis before choosing equipment.
Future loads: If you plan to add an EV or heat pump within a few years, size for that usage now, since adding panels later usually costs more per watt, and remember the export-capacity limit for new participants.
Hail and wind: Ask about the panels’ hail rating, how the roof attachments are made, and whether your homeowner’s policy covers the array.

🔋 Storage & Usage
Are Community Solar and Battery Storage Worth It in Kansas?
Community solar is limited and depends on your utility in Kansas. Batteries are mostly worth it for backup rather than bill savings, and homeowner-owned batteries installed in 2026 no longer get the federal credit.
Community solar: Some Kansas utilities and co-ops have offered community or shared solar programs, for example Midwest Energy’s project for its members. Availability and terms vary by territory. Before subscribing, check how credits are calculated, whether there is an exit fee, and how long the contract lasts.
Battery storage: EnergySage reports that a 13.5 kWh battery, about the size of a Tesla Powerwall 3, typically costs about $15,600 before incentives. That is a national figure for the first half of 2026, so Kansas quotes will differ. Because monthly surplus earns less than retail, a battery can help use more of your own solar, but the bill savings rarely cover its cost on their own. Its main value is keeping essentials running through outages. Model your case with the battery storage calculator, and compare it with the cost of a standby generator.
EnergySage's marketplace data put the Kansas average at $2.72 per watt in July 2026, before incentives. That makes a 9 kW system about $24,500. EnergySage's average Kansas quote was a larger 12.05 kW system at about $32,800. Prices vary by city, equipment and roof, so compare at least three quotes.
In our base case, about 13 years for a 9 kW system bought with cash at $2.72 per watt, with no federal credit. Across lower and higher installed prices and different net-metering credit shares, payback ranges from roughly 11 to 16 years. The inputs are 14.56¢/kWh, a 2% yearly rate rise, and 0.5% yearly panel degradation.
Not for a system you own. The 30% federal credit (§25D) ended for expenditures made after December 31, 2025, and the IRS treats a solar expense as made when installation is complete. Kansas has no state solar tax credit, but new claims for the solar property-tax exemption last 10 tax years. Leases and PPAs may still pass on a business credit (§48E) if the system is in service by the end of 2027. This is not tax advice.
Evergy and Liberty must offer net metering. Solar output first offsets what you use within the billing period. For systems that began operating after July 1, 2014, leftover monthly surplus is credited at the utility's system average cost of energy, which is below the retail rate. New participants from January 1, 2026 also face an export-capacity limit. Size your system close to your own usage.
It can be, mainly for homeowners who plan to stay 13 years or more, have a mostly unshaded south- or west-facing roof, and get quotes near or below the Kansas average. Kansas electricity is cheaper than the national average, so payback is slower than in high-rate states. In our model a 9 kW system nets about $25,600 over 25 years, while EnergySage's own Kansas estimate is lower, so treat the result as a range.
