Kansas solar in 2026 has one unusual structural protection most coverage doesn't emphasize: the Kansas Supreme Court struck down Evergy's solar-only demand charge in April 2020 as illegal price discrimination. KS solar buyers are court-protected from solar-only fees — a notable contrast with states like Alabama where capacity charges have been upheld by federal courts.
The headline:
- Net metering by statute (K.S.A. 66-1263..1271, enacted May 2009, amended 2014 and 2024 HB 2527). Two IOUs required: Evergy (dominant) and Liberty / Empire District (southeast). Co-ops and municipals NOT required.
- Within the month: exports OFFSET RETAIL within consumption via monthly banking (about $0.136/kWh retail on Evergy).
- MONTHLY NEG true-up: excess (export > consumption that month) pays about $0.024/kWh wholesale. Monthly — NOT annual. Summer surplus cannot offset winter use.
- Right-sizing CRITICAL — solarreviews recommends about 75% of normal sizing (7.2 kW vs 9 kW) to minimize monthly NEG that earns only $0.024 instead of $0.136.
- Kansas Supreme Court April 2020: Evergy's solar-only demand charge ($3/kW winter, $9/kW summer) was REVERSED as price discrimination. KCC returned DG to standard rate in Feb 2021. No solar-only demand charge in KS today.
- System size cap evolved by amendments: from January 1, 2026 generating capacity ≤ 50% of export capacity; from July 1, 2026 generation ≤ export + 50% with export-limiting device.
- 2030 EXPIRATION RISK: KS net metering law has a sunset date of 2030 per legislative testimony.
- Federal §25D = $0 for 2026 purchases (OBBBA repeal).
- Property tax EXEMPT 10 YEARS only (K.S.A. 79-201 Eleventh) — NOT permanent for new 2026 installs; panels qualify, batteries do NOT.
- Sales tax (6.5% + local, about 8.7% combined) NOT EXEMPT — about $2,100-2,800 added cost.
- NO state income tax credit residential (commercial cogeneration credit is BUSINESS only).
- NO SREC market, no RPS (RPS softened to voluntary in 2015).
- NO statewide battery rebate. Federal storage $0.
- Typical payback 12-15 years at $2.80/W with federal $0.
Sources citing 7-10 year payback (solarreviews 9 years, usa-net-zero 7-10) all use the live 30% federal credit — outdated. Real 2026 payback runs 12-15 on right-sized systems.
The case for Kansas solar in 2026: court-protected from solar-only fees (rare, valuable structural plus), real retail offset within monthly consumption, cheap install pricing. The drags: monthly NEG true-up (worse than annual), federal $0, sales-not-exempt, 10-year-only property exemption, 2030 statutory sunset.
What changed federally — and what's still on Kansas quotes that shouldn't be
The federal Residential Clean Energy Credit (§25D) — the 30% homeowner credit — was repealed for systems installed after December 31, 2025. For 2026 Kansas buyers, the federal credit on a purchased system is $0. The same applies to home batteries purchased outright. The §48E commercial credit (30%) still exists, but only for leased or third-party-owned systems where construction begins before July 4, 2026 — and the lessor claims it, not you. Full federal context here.
The repeal came through the One Big Beautiful Bill Act (P.L. 119-21), signed in July 2025. KS-focused solar sites are unusually behind on this: solarreviews, palmetto, SmartEnergyUSA, usa-net-zero, and rebateatlas all still cite "30% ITC" on their Kansas pages (rebateatlas specifically: "through 2032"; usa-net-zero and SmartEnergyUSA: "30% battery credit") — all outdated and false. If a 2026 KS quote includes "30% federal solar tax credit" on a purchase, ask the contractor to redo the math with $0 federal and verify with IRS.
VERIFIED 2026-06 · IRS §25D repeal under OBBBA P.L. 119-21Demand charge struck down — the Kansas Supreme Court 2020 ruling
This is the most underappreciated Kansas solar fact in 2026, and it's a structural protection that several other states' buyers don't enjoy.
Timeline:
- 2018: KCC (Kansas Corporation Commission) approved an Evergy demand charge specifically for DG / solar customers — $3/kW in winter, $9/kW in summer (sometimes exceeding $100/month for typical residential solar).
- April 3, 2020: the Kansas Supreme Court REVERSED the KCC approval — found the solar-only charge was "price discrimination" prohibited by Kansas statute. The court ruled that utilities cannot single out solar / DG customers for differential rate treatment.
- February 2021: KCC returned DG customers to the standard two-part residential rate and REJECTED Evergy alternatives ($3/kW grid access fee, $35 minimum bill). Solar and standard customers are now on the same rate.
- Result: NO solar-specific demand charge, grid fee, or minimum bill in Kansas today. Court-protected.
This is a major contrast with other states:
- Alabama: federal court UPHELD Alabama Power's Rider RGB capacity charge ($5.41/kW/month) in March 2026. AL solar customers pay this recurring fee; KS customers don't.
The Kansas Supreme Court protection is unusual nationally and is a real, underappreciated structural plus for KS solar buyers. It removes a category of risk that exists in many other states.
VERIFIED 2026-06 · Kansas Supreme Court April 3, 2020 ruling; KCC February 2021 orderNet metering — monthly retail offset + MONTHLY NEG avoided
Kansas's net metering statute is the Net Metering and Easy Connection Act (K.S.A. 66-1263..1271), enacted May 2009 and amended in 2014 and again in 2024 (HB 2527). KCC is the regulator.
Who must offer: two IOUs are required — Evergy (dominant statewide; serves Wichita, Kansas City KS metro, Topeka; formerly Westar + KCP&L) and Liberty Utilities (formerly Empire District; small footprint in southeast KS). Co-ops and municipals are NOT required — they may offer NM or may not; terms vary widely.
Mechanism — two stages:
Stage 1 (within the month):
- Exports OFFSET RETAIL within monthly consumption via monthly banking — credited at full retail (about $0.136/kWh on Evergy).
- Within-month surplus banks (in kWh) and applies to later usage that month.
Stage 2 (monthly true-up):
- If export exceeds consumption in any given month, the excess is net excess generation (NEG) for that month.
- NEG is paid at system average cost / wholesale rate, about $0.024/kWh (solarreviews 2.4¢).
- MONTHLY true-up — meaningfully worse than annual true-up states because summer surplus cannot offset winter use.
Why right-sizing is critical in Kansas:
Because the true-up is monthly (not annual), an oversized system that produces more than you use in any given month dumps the excess at $0.024 instead of $0.136 — roughly 1/6th the value. solarreviews recommends sizing to about 75% of normal sizing (e.g., 7.2 kW vs 9 kW) to minimize monthly NEG and capture more of your export at the retail-offset rate.
System size cap evolved by amendments:
- Pre-July 1, 2014: 25 kW residential.
- From July 1, 2024 (HB 2527): up to 150 kW per K.S.A. 66-1267 sizing formula.
- From January 1, 2026: generating capacity ≤ 50% of export capacity.
- From July 1, 2026: generation ≤ export + 50% with export-limiting device.
New 2026 installs follow current sizing rules.
VERIFIED 2026-06 · K.S.A. 66-1263..1271; HB 2527 (2024); KCC; solarreviews2030 expiration risk
Kansas net metering law has a sunset date of 2030 per legislative testimony. The aggregate participation cap (1% → 5% by 2027) is also being approached. After 2030, the compensation framework for new installs is uncertain.
HB 2228 (status unclear as of mid-2026) tried to remove the 2030 sunset. Without legislative action, new 2026 installs face uncertainty about what happens to their compensation in 2030.
Existing systems are likely grandfathered (consistent with past practice), but verify with KCC and your utility before assuming long-term continuity at current rates. If you're planning a large multi-decade investment in Kansas solar, the 2030 expiration is a real risk to weigh.
Sales tax — NOT EXEMPT
Kansas does not exempt residential solar from sales tax. KS state sales tax is 6.5%, plus local rates (combined typically about 8.7%).
EnergySage directly confirms: "no relief from sales tax in Kansas." usa-net-zero incorrectly claims solar is exempt — that's wrong.
On a typical KS residential install this is about $2,100-2,800 of REAL added cost the installer must include. Your quote SHOULD include sales tax.
Property tax — EXEMPT 10 YEARS ONLY (NOT permanent, batteries NOT covered)
Kansas exempts residential solar from property tax for 10 YEARS under K.S.A. 79-201 Eleventh ("renewable energy generation property").
Two critical nuances most coverage misses:
- NOT PERMANENT FOR NEW 2026 INSTALLS. Pre-December 2016 enrollments got a permanent exemption. From December 2016 onward, including all new 2026 installs, the exemption is 10 years only — then the added home value becomes property-taxable on your annual assessment.
- PANELS QUALIFY, BATTERIES DO NOT. Court-ruled exclusion. If you add storage, the battery's added value is NOT covered by the exemption.
What the exemption is worth: about $166/year for 10 years (about $1,660 total) at KS effective residential property tax rate of 1.33% on a typical solar-driven home value uplift of about $12,500. Automatic — no application required.
rebateatlas and usa-net-zero describe this as "100% / permanent" — both miss the 10-year limit and the battery exclusion. Don't read those framings as the long-term reality for new 2026 installs.
VERIFIED 2026-06 · K.S.A. 79-201 Eleventh; Kansas Department of Revenue; rebateatlasNo state income tax credit, no SREC, no RPS
Kansas has NO state solar income tax credit for residential. rebateatlas confirms: "no direct state income tax credit." palmetto notes a 10% commercial cogeneration credit (up to $50M) exists for BUSINESS investments — NOT residential rooftop.
Kansas has NO mandatory Renewable Portfolio Standard and NO SREC market. SmartEnergyUSA directly: "no SREC market; voluntary Renewable Energy Standard, not mandatory." The originally-mandatory RPS was softened to voluntary in 2015.
There is no SREC revenue stream available to KS residential solar owners. Any quote citing "SREC revenue" is fictional.
Battery — no rebate, property exemption excludes batteries
No statewide battery rebate in Kansas. Federal storage credit is $0 (§25D repealed for storage purchase). And as noted above, the K.S.A. 79-201 property tax exemption does NOT cover batteries (court-ruled).
Arbitrage gap under monthly NEG true-up: retail $0.136 vs wholesale NEG payment $0.024 = gap about $0.11/kWh — large, but only matters for monthly NEG excess. Within-consumption exports already get retail offset, so right-sized systems don't see the arbitrage gap on most of their export.
The Kansas Supreme Court 2020 ruling means no solar-only demand charge to avoid with a battery (some other states' batteries help dodge demand charges; not relevant here, since there isn't one).
Resilience case is real for KS: tornado alley (especially central and western Kansas), severe weather, summer storm outages.
REAP (USDA Rural Energy for America Program) — applies only to agricultural / rural businesses, NOT residential, AND was halted by 2025 executive order. Don't budget.
The honest payback — middle-tier, right-sizing matters
At default install pricing of about $2.80/W (EnergySage $2.76; solarreviews ~$2.92 — KS is among the cheaper US install markets), typical Kansas solar-only payback runs in the 12-15 year range with the federal $0 + monthly NEG true-up.
- solarreviews cites 9 years — uses the live 30% federal credit. Don't use that figure for 2026.
- usa-net-zero cites 7-10 years — also uses live federal. Don't use.
- Under the actual 2026 repealed-federal case, expect 12-15 years on right-sized systems.
- Oversized systems that hit monthly NEG excess at the $0.024 wholesale rate pay back materially longer.
- solarreviews's 75%-of-normal-sizing recommendation (7.2 kW vs 9 kW) minimizes monthly NEG and captures more export at retail offset.
Where Kansas fits regionally:
- Nebraska (neighbor; net metering with ANNUAL NEG true-up — slightly better than KS's monthly because summer surplus can offset winter): about 14-17 years (lower retail $0.114 vs KS $0.136 partially offsets).
- Missouri (neighbor; Evergy also operates there with similar mechanism): comparable mid-tier.
- Oklahoma (neighbor): regional context.
- Colorado (Xcel net metering with retail credit, higher retail): meaningfully better.
KS is structurally middle-tier: the Kansas Supreme Court 2020 protection against solar-only fees is a real plus that most coverage doesn't emphasize; the LB 436-era net metering framework works for right-sized systems; but the monthly NEG true-up (worse than annual), the 2030 expiration risk, the 10-year-only property exemption, and the federal $0 keep ROI modest, not stellar.
KS is among the 10 sunniest US states by solar resource, but adoption is LOW (under 0.23% of generation per 2019 data). Evergy has about 1,550 KS net metering customers — only about 0.4% of its residential base. The 2018-2020 demand-charge uncertainty depressed adoption; the 2020 court reversal removed that drag, but adoption is still modest. Kansas ranked 46th nationally on solar policy in 2021.
VERIFIED 2026-06 · eia.gov; solarreviews; EnergySageHow to read this — Kansas's case for solar
KS solar in 2026 is right-sizing-driven with one notable structural protection (court-blocked solar-only fees).
- Right-size to about 75% of normal sizing. Monthly NEG excess pays only $0.024/kWh vs $0.136 retail offset within consumption — a roughly 6x penalty for oversizing. solarreviews's 75% rule is the practical guideline.
- The Kansas Supreme Court 2020 protection is real and valuable. No solar-only demand charge in KS. If you've heard of states with capacity charges hurting solar ROI, KS is structurally protected from that category of risk.
- Verify your specific utility's tariff. Evergy and Liberty / Empire District are required to offer NM. Co-ops and municipals are NOT — terms vary. If you're not on an IOU, verify in writing before signing.
- Watch the 2030 expiration. KS net metering has a sunset date of 2030 per legislative testimony. Existing systems will likely grandfather but verify; new installs face long-term uncertainty.
- Reject any quote citing the federal 30% credit on a 2026 purchase. Dead. Many KS solar pages still cite "30% through 2032" — outdated.
- Reject any "KS state solar tax credit" claim for residential. Doesn't exist. (The 10% commercial cogeneration credit is BUSINESS only.)
- Reject any quote citing SREC revenue. KS RPS is voluntary — no market.
- Don't accept sales tax exemption. KS 6.5% + local applies — about $2,100-2,800 of real cost. (Some sites wrongly claim exempt.)
- Understand the property tax exemption's limits. K.S.A. 79-201 exempts solar value for 10 years, not permanently — and batteries are NOT covered (court-ruled). Plan for property tax kicking in around year 11.
- Battery for resilience, not ROI — no rebate, federal storage $0, property exemption excludes batteries. Tornado alley + severe weather is the real case for backup.
- REAP is not available — agricultural/rural-business only AND halted by 2025 executive order.
If you're on Evergy or Liberty, can right-size to about 75% of normal load, and you can complete installation in time to avoid the 2030 risk window, Kansas solar makes a respectable middle-tier case in 2026 — payback in the 12-15 year range. The structural court protection against solar-only fees is a real, underappreciated plus. If you were counting on the federal credit, on a state credit, on full retail compensation for excess generation, on permanent property tax exemption, on an SREC market, or on REAP — none of those apply.

Before you commit:
- Reject any 30% federal credit on a 2026 purchase. Repealed. Many KS solar pages still cite "30% through 2032" — outdated.
- Understand the monthly net-metering true-up. Exports offset consumption at retail (about $0.136) within the month, but monthly excess (NEG) pays only about $0.024 wholesale — and unlike annual-true-up states, summer surplus can't offset winter. Right-size to about 75% of annual use.
- Good news: Kansas solar is court-protected from solar-only fees. The Kansas Supreme Court struck down Evergy's solar demand charge in 2020 as price discrimination — a notable contrast with Alabama, where a federal court upheld Alabama Power's solar capacity charge in 2026.
- But watch the 2030 expiration. KS net metering law has a sunset date of 2030; new installs face uncertainty about compensation after that. Legislative fixes (HB 2228) are pending.
- Property tax exemption is 10 years, not permanent. K.S.A. 79-201 exempts solar value for 10 years (then it becomes taxable) — and it covers panels, NOT batteries. Saves about $166/year for a decade.
- Don't assume a sales tax exemption. KS 6.5% plus local applies — no residential relief (some sites wrongly claim exempt).
- Don't budget for SREC revenue. KS RPS is voluntary — no market.
