Missouri solar incentives in 2026
Last updated · every MO program below is verifiable against the sources at the foot of this page.
The most valuable solar incentive in Missouri right now is Intermittent utility rebates. Overall, the state's incentive stack rates as limited compared with the rest of the country.
The federal credit is gone — start here
The 30% federal residential clean energy credit (Section 25D) ended for systems installed after December 31, 2025. If you are buying a system in Missouri this year, there is no federal credit. That is a roughly $7,560 swing on an $25,200 system compared with 2025 pricing, and it is why state programs matter more now than they did a year ago.

Missouri solar tax credit
There is no Missouri solar tax credit in 2026, and no federal one either — Section 25D ended for systems installed after December 31, 2025. That makes your electricity rate and your utility's export credit the whole of the economics here.
Missouri solar rebates and grants
Ameren and Evergy have offered rebates tied to renewable standard compliance; availability comes and goes. Rebate and grant programs are funding-limited and have opened and closed mid-year before, so confirm the current round is open before counting on it.
Some Missouri utilities (notably Ameren and Evergy historically) have offered solar rebates tied to renewable standard compliance; availability comes and goes. No state tax credit.
Net metering and export rates in Missouri
Missouri requires net metering up to 100 kW, but monthly excess generation is credited at avoided cost rather than retail, so oversizing is penalized.
Compare this with net metering in every other state.
Export rules deserve to be read as an incentive. In a retail net metering state, every exported kilowatt-hour is worth the full retail rate; under net billing or avoided-cost compensation, the same kilowatt-hour can be worth a third of that. For a Missouri home at an assumed $0.13/kWh, that difference compounds across a 25-year system life.
What this means for your numbers
A typical 8 kW system in Missouri costs roughly $19,200–$25,200 installed before incentives, producing about 10,800 kWh a year and saving around $1,157 in year one — a simple payback near 17–22 years with no incentives applied. Anything in the table above shortens that.
Frequently asked questions
What are Missouri solar tax credits worth in 2026?
Missouri offers no residential solar income tax credit in 2026, and the 30% federal credit ended for systems installed after December 31, 2025. There is no state tax benefit to claim at all, so the economics rest on your electricity rate and export credit.
Does Missouri have solar rebates?
Yes. Ameren and Evergy have offered rebates tied to renewable standard compliance; availability comes and goes. Rebate programs in MO are funding-limited and have historically opened and closed mid-year, so confirm the current round is still accepting applications before you count the money.
Is there a Missouri solar property tax exemption?
No. Missouri does not exempt residential solar from property tax assessment, so a system that increases assessed value can increase your property tax. Assessment practice varies by county — ask your local assessor how they treat rooftop solar.
What solar incentives are available in Missouri in 2026?
Some Missouri utilities (notably Ameren and Evergy historically) have offered solar rebates tied to renewable standard compliance; availability comes and goes. No state tax credit. Because the federal Section 25D credit ended for systems installed after December 31, 2025, these state, local and utility programs are now the entire incentive picture for a purchased system.
Is there still a 30% federal solar tax credit in Missouri?
No. The 30% federal residential clean energy credit (Section 25D) ended for systems installed after December 31, 2025 under the One Big Beautiful Bill Act. Any quote or website still applying 30% to a 2026 purchased installation is out of date. Leased and PPA systems can still benefit indirectly, because the third party that owns the system may claim the commercial 48E credit through 2027 and pass some of the value through in pricing.
Does Missouri have net metering?
Missouri requires net metering up to 100 kW, but monthly excess generation is credited at avoided cost rather than retail, so oversizing is penalized. Export rules are effectively an incentive — often the largest one — because they set what every kilowatt-hour you do not use on site is worth.
How much do incentives change the cost of solar in Missouri?
Before incentives, a typical 8 kW system in Missouri runs roughly $19,200–$25,200. Ameren and Evergy have offered rebates tied to renewable standard compliance; availability comes and goes — the value depends on current funding. See our full Missouri cost breakdown for payback math.
