On the physical side, Kansas is one of the stronger places in the country to put panels on a roof. Production of 1,567 kWh per installed kW is top-tier for any state that still nets at full retail, and the system price sits at the national average. On the financial side it comes out middling. Understanding why that gap exists is the useful part, because the reason is not something an installer can fix and it is not something the weather explains.
The Physical Case Is Genuinely Strong
What Kansas has | Figure | National context |
|---|---|---|
Annual output per kW | 1,567 kWh | Top-tier for a full-retail netting state |
Peak sun hours | 5.53 | Among the strongest in the central states |
Typical system cost | 6.71 kW at about $19,459 | At the national average, $2.90 per watt |
Electricity price growth | 2.17% a year | Modest; barely 2% a year |
The first three rows are as good as the central plains offer. The fourth is the problem. Solar is in part a bet that the price of electricity climbs, and Kansas rates have been climbing at barely 2% a year. The panels work beautifully; the thing they are protecting you from is moving slowly.
That is why Kansas produces a payback in the middle teens rather than the single digits its sunshine might suggest. Strong production sets how much a system makes. Your rate, and the direction it is heading, set what that output is worth.

Monthly Netting Makes an Unknown Rate Mostly Harmless
Kansas net metering runs under K.S.A. 66-1266 for the investor-owned utilities, principally Evergy and Liberty. Your generation is netted against your consumption each month at the full retail rate. Whatever is left over at the end of the billing period is credited at no less than 100% of the utility’s monthly system average cost of energy.
That last figure is a wholesale-level number, it floats month to month, and no utility states it as a rate a homeowner can look up. Ordinarily that would be a serious problem for anyone trying to model a twenty-five year investment.
Here it mostly is not, and the reason is the netting window. Because the comparison happens across a whole month rather than instant by instant, generation at noon on Tuesday freely offsets consumption at 9pm on Friday. A system sized to your monthly usage sends very little to that unstated rate at all, which means that wholesale-level credit applies to a small slice of your output.
How well the system matches your monthly use | What the year returns | Break-even |
|---|---|---|
Closely matched, little month-end surplus | $1,498 | About 13 years |
Slightly oversized | $1,311 | About 15 years |
Well oversized for the household | $1,062 | About 18 years |
Methodology: these are EcoGen America’s calculations on a 6.71 kW system at $19,459 gross ($2.90 per watt, EcoGen Solar Cost Index as of March 1, 2026) producing 10,515 kWh a year against household use of 876 kWh a month. Offset power is valued at the 14.84¢ statewide average residential rate (EIA Electric Power Monthly, March 2026 edition), which is ranking context rather than a rate anyone pays: Evergy Kansas Central, Evergy Kansas South and Evergy Metro, about 80% of Kansas homes between them, each file their own residential rate, so rerun the year and the payback with the rate on your own bill. Month-end surplus is valued at 3¢ because each utility recalculates its system average cost monthly. Figures are simple payback before financing, rate escalation and degradation.
The practical lesson is in the first row: match the system to your monthly consumption and the month-end credit barely reaches you.
One exception matters. Customers who moved to a time-of-use rate after July 1, 2024 are netted within the time-of-use period rather than across the whole month, under House Bill 2527. That is a shorter window, and it makes when you use power matter considerably more. If you are on or considering a time-of-use rate, ask specifically how your generation will be netted before you size anything.
The Capacity Cap Is Growing, Not Closing
Kansas limits total net-metered capacity on a first-come basis under K.S.A. 66-1265, and the limit steps up every July: 2% of peak demand from July 2024, 3% from July 2025, 4% from July 2026 and 5% from July 2027.
It is worth being plain about the direction of that, because a cap sounds like a deadline and this one is the opposite. The allowance available to Kansas homeowners is scheduled to more than double between 2024 and 2027. Anyone using the cap to press you into signing this month is describing a shrinking window that is in fact expanding.
That said, it is a first-come limit and it is finite in any given year, so it is a fair question to put to your utility: is capacity currently available on my circuit, and is my application likely to be accepted this year. A dated answer costs nothing to obtain.
The Property Tax Exemption Has Two Limits Worth Knowing
Kansas offers no state income tax credit for residential solar and no rebate. It does offer a property tax exemption on the added value of the system, and that exemption carries two restrictions that catch people out.
- It runs for ten taxable years only, for any exemption applied for after December 31, 2016. It follows the year the installation is completed. A twenty-five year system is therefore unexempt for its last fifteen years.
- It does not cover battery storage. Guidance issued by the Director of the Division of Property Valuation on September 17, 2024 concluded the renewable exemption does not extend to battery energy storage attached to a renewable energy system. If storage is part of your plan, that is a direct cost consequence.
- The federal residential credit is $0 for purchased systems whose installation is completed after December 31, 2025 under Public Law 119-21. Third-party PPAs are prohibited in Kansas and no residential third-party provider operates here, so the lease and PPA route that carries the separate Section 48E business credit in other states is closed. Buying is the only path, and every figure on this page assumes no credit at all.
Where the Kansas Case Falls Apart
- If a quote is sized well above your monthly usage. Kansas rewards a system matched to your monthly consumption, and the surplus goes to a wholesale-level figure, recently in the 2¢ to 3¢ range, that each utility recalculates monthly; ask yours for the current figure in writing.
- If a cooperative or municipal utility serves you. K.S.A. 66-1266 covers the investor-owned utilities only. Kansas City BPU and the cooperatives set their own export terms, so get the export credit rate in writing first; if it pays a wholesale-level rate for every exported kilowatt-hour rather than netting monthly, the well-oversized row above is your starting point, not the matched row.
- If a projection assumes fast electricity price rises. Kansas has managed 2.17% a year. A model built on more than that is assuming something Kansas has not done.
- If you are on a time-of-use rate and have not checked the netting. The shorter window changes the arithmetic and most quotes will not have modeled it.
- If you plan to move before year 13. Thirteen years is the good case here, so a sale before break-even leaves the rest of the return riding on what the next buyer pays for the system.
For a Kansas household on an investor-owned utility, staying put, with a system matched to its own consumption, thirteen years on twenty-five year equipment is a sound outcome achieved without a tax credit or rebate. The state’s sunshine and low installed prices carry it, and the modest rate trajectory is what keeps it from being remarkable. Our Kansas incentives guide covers the exemption detail, and the Kansas installer list covers who works here.

Kansas Solar FAQs
For a household on an investor-owned utility with a system matched to its own consumption, yes, at a simple payback around 13 years on our figures. It stretches to about 18 years for a well oversized system. Kansas has top-tier production of 1,567 kWh per kilowatt and a system price at the national average, about $19,459 for the typical system, and the thing holding it back is that electricity prices have risen only about 2.17% a year.
Under K.S.A. 66-1266, investor-owned utilities net your generation against your consumption each month at the full retail rate, and credit whatever is left at the end of the billing period at no less than 100% of the utility’s monthly system average cost of energy. That is a wholesale-level figure that floats monthly and is not stated anywhere a homeowner can look it up. Because the netting runs across a whole month, a well-matched system sends very little to that rate.
Yes, and it is growing rather than closing. K.S.A. 66-1265 sets a first-come limit on total net-metered capacity that steps up every July: 2% of peak demand from July 2024, 3% from July 2025, 4% from July 2026 and 5% from July 2027. Anyone using the cap to create urgency is describing a shrinking window that is actually expanding. It is still finite in a given year, so it is worth asking your utility whether capacity is available on your circuit.
No. Guidance issued by the Director of the Division of Property Valuation on September 17, 2024 concluded that the renewable energy property tax exemption does not extend to battery energy storage attached to a renewable energy system. The exemption also runs for only ten taxable years following completion for anything applied for after December 31, 2016, rather than for the life of the system, so a twenty-five year installation is unexempt for its final fifteen years.
Yes, substantially. Customers who moved to a time-of-use rate after July 1, 2024 are netted within the time-of-use period rather than across the whole month, under House Bill 2527. That is a much shorter window, so when you use power starts to matter a great deal more and a system that would be well matched on monthly netting may not be. Ask specifically how your generation will be netted before sizing anything.
