Is solar worth it in Missouri in 2026? Yes for most homeowners. Here's how to know.

Yes for most Missouri homeowners. Specifically: yes if you own your home, plan to stay at least 5 years, have a south-facing or west-facing roof with limited shade, use at least 800 kWh of electricity per month, and have either federal tax appetite or are willing to use Solar Assure's 25 percent Midas Wealth pass-through of the federal Section 48E commercial credit. Under those conditions, a typical 10 kW Ameren Missouri system at $20,250 net cost (after Midas Wealth) pays for itself in approximately 9 years and delivers approximately $58,595 in net 25-year value. The federal residential ITC under Section 25D expired December 31, 2025 under the One Big Beautiful Bill Act, but the Section 48E commercial credit remains active and Solar Assure passes 25 percent through to residential customers. Missouri's RSMo 386.890 1:1 retail rate net metering remains favorable. Solar is not worth it in 5 specific cases listed below.

First, do you own your home? If you rent, your landlord owns the roof and the solar economics do not work. Second, are you planning to stay at least 5 years? Solar pays back in 7 to 9 years for typical Missouri scenarios; if you sell before payback, you are betting on home value uplift to recoup. Third, does your roof get good sun? South-facing or west-facing exposure with minimal shade is best. Heavily shaded roofs cut production by 30 to 50 percent and significantly extend payback. Fourth, do you use enough electricity? At least 800 kWh per month is a reasonable threshold; below 600 kWh per month is usually a no. Fifth, are you OK with the Section 48E commercial credit pass-through structure? Solar Assure's 25 percent Midas Wealth check requires comfort with a sale-leaseback arrangement (the credit goes to a tax equity investor and the value flows back to the customer). If yes to all five, solar is likely worth it. If no to any, run the math more carefully or consider waiting.

Five specific scenarios where solar is not worth it in Missouri: (1) Planning to sell within 3 years. Even with home value uplift, transaction costs and the imperfect price capture on solar typically mean a net loss. (2) Heavily shaded roof with no good options. If even the best section of your roof gets less than 4 hours of unobstructed sun per day, production drops below the level where payback math works. (3) Very low electric usage. Households using less than 600 kWh per month do not have enough offset opportunity to justify the upfront cost. (4) Major roof replacement needed within 5 years. The cost of removing and reinstalling panels is typically $1,500 to $3,000 and erodes payback. Better to replace the roof first and install solar after. (5) High-interest debt or short-term cash needs. If you have credit card debt or other high-rate obligations, paying those down typically delivers better returns than solar. See our When Not to Install Solar guide for the full breakdown of all 8 scenarios.

Yes. The federal residential clean energy credit under Internal Revenue Code Section 25D expired December 31, 2025 under the One Big Beautiful Bill Act signed by Congress in July 2025. Systems installed in 2026 or later cannot claim the 30 percent residential ITC. Many websites still reference the 30 percent credit as if it were active, but those references are out of date. The federal commercial clean electricity credit under Section 48E remains active for projects placed in service through 2032 (with a step-down beginning in 2033). Solar Assure passes 25 percent of the Section 48E credit value back to residential customers as the Midas Wealth check, reducing effective system cost from approximately $2.70 per watt to approximately $2.025 per watt net. The mechanism is different from the old residential ITC but the dollar value is similar.

Three reasons. First, Missouri RSMo 386.890 (Net Metering and Easy Connection Act) provides 1:1 retail rate net metering throughout the year, with avoided cost true-up only at annual reconciliation. This is significantly more favorable than Kansas net metering and means almost every kWh produced offsets a kWh of retail-rate consumption. Second, Missouri electric rates are rising fast: Ameren Missouri received approval for a 12 percent rate increase effective June 1, 2025 and another double-digit rate case is pending. Evergy Missouri Metro filed a 14.9 percent rate case in February 2026 with a January 2027 effective date. AWS Project Green data center approved November 2025 in Montgomery County and the Project Spade adjacent development add 780 more acres of new load. Higher rates and more upward pressure ahead means solar locks in a hedge against future bill increases. Third, Solar Assure's 25 percent Midas Wealth pass-through of Section 48E commercial credit recovers most of what the residential ITC delivered, in dollar terms.

Solar Assure's standard residential pricing in Missouri is $2.70 per watt installed (gross). After Solar Assure's 25 percent Midas Wealth pass-through of the federal Section 48E commercial credit, effective net pricing is approximately $2.025 per watt. For typical Missouri residential system sizes: 8 kW system $21,600 gross / $16,200 net, 10 kW system $27,000 gross / $20,250 net, 12 kW system $32,400 gross / $24,300 net. This is well below the EnergySage Missouri marketplace average of $2.49 to $2.93 per watt gross for 2026 and dramatically below the typical commission-driven sales-team installer at $3.30 to $3.90 per watt. Solar Assure's pricing does not include commissions because Solar Assure does not employ commission salespeople. The savings flow directly to customers. See our Missouri Solar Cost guide for full system-by-system pricing.

Approximately 7 to 9 years for most Missouri scenarios in 2026. A typical 10 kW Ameren Missouri system at $20,250 net cost saves approximately $2,020 in Year 1 and pays back in approximately 9 years. A 10 kW Columbia Water and Light system (CWL still has a $5,000 utility rebate after the federal ITC expiration) at $15,250 net pays back in approximately 7 years, the best Missouri scenario currently available. A smaller 8 kW system pays back in approximately 9 years; a larger 12 kW system also pays back in approximately 9 years (Missouri's 1:1 retail rate net metering means system size has limited effect on payback percentage). For complete scenario-by-scenario math, see our Missouri Solar Payback 2026 guide.

You should account for them in the math. Ameren Missouri received approval for a 12 percent rate increase effective June 1, 2025, and Ameren has another rate case pending at the Missouri Public Service Commission. The Consumers Council of Missouri reports that Ameren summer bills have risen 34.5 percent since 2020 and winter bills have risen 32.9 percent. Ameren is also citing AWS Project Green (data center approved November 2025 in Montgomery County, Missouri) and Project Spade (adjacent 780-acre development) as drivers of new load that requires generation buildout. Missouri SB4 (signed April 2025) enables Construction Work in Progress billing, allowing Ameren to recover construction costs in customer bills before plants are operational. The combined picture: rates are rising, more increases are virtually certain, and solar is one of the few ways a homeowner can hedge against the trend by locking in a per-kWh cost for 25 years.

Missouri's residential rooftop solar treatment in 2026 is uncertain due to the 2022 Missouri Supreme Court ruling in Johnson v. Springfield Solar 1, LLC, No. SC99441, 648 S.W.3d 101 (Mo. banc Aug. 9, 2022), which struck down RSMo 137.100(10) as unconstitutional under Article X Section 6 of the Missouri Constitution. The ruling technically removed the prior statutory exemption, but Missouri counties have generally continued to not assess residential rooftop solar in practice (the State Tax Commission's Chapter 7-11 Assessor Manual provides guidance). Functionally most Missouri homeowners still do not see property tax bills increase after solar installation, but the legal certainty is weaker than it was before 2022. Read our Missouri Solar Property Tax Explained guide for the full breakdown including the seven failed legislative fix attempts since 2022.

Missouri has the strongest HOA solar protection in the region. RSMo 442.404 (Missouri's HOA solar access statute, enacted via SB 820 in 2022) prohibits any covenant or deed restriction from limiting or prohibiting solar panel installation on a homeowner's rooftop. The Missouri Supreme Court unanimously confirmed this in Eikmeier v. Granite Springs Home Owners Ass'n, Inc., 2026 WL 202043 (Mo. banc Jan. 23, 2026), holding that RSMo 442.404.3 applies retroactively to all covenants regardless of recording date, and that rear-only or non-street-facing rules are unenforceable when they reduce production. Read our Missouri HOA Solar Law guide for the full breakdown of what HOAs can and cannot do, plus the four-part test from RSMo 442.404.3(2). Kansas does not have an equivalent state-level statute.

Solar Assure's minimum system size is approximately 5 kW (smaller systems do not benefit enough from the Midas Wealth pass-through structure to be economic for the customer or for us). There is no income requirement for Solar Assure customers because the 25 percent Midas Wealth check is a sale-leaseback structure rather than a tax credit; the customer does not need federal tax appetite to capture the value. This is one of the primary advantages of Solar Assure's structure post-Section 25D expiration: under the old residential ITC, customers without federal tax liability could not capture the 30 percent credit and had to carry it forward. Under Solar Assure's structure, the value flows directly back to the customer regardless of their federal tax position.

If you are planning to move within 3 years, solar is generally not worth it in Missouri. Even with the home value uplift that solar typically provides (multiple national studies suggest residential solar adds approximately $4 per watt to home sale value, though this varies by buyer and market), transaction costs and imperfect price capture mean a net loss for the seller. If you are planning to move in 4 to 6 years, the math is borderline and depends on your specific situation: high electric bills and good roof conditions tip toward yes. If you are planning to stay 7+ years, solar is almost certainly worth it for a Missouri homeowner who otherwise meets the 5-question test. Solar Assure's installations include documentation packages designed for transferability if you do sell mid-payback.

Before committing to solar, three alternatives are worth evaluating. First, energy efficiency upgrades: insulation, air sealing, smart thermostat, LED lighting, and ENERGY STAR appliances can reduce consumption 15 to 30 percent for a fraction of solar cost. The Missouri Department of Economic Development weatherization program may apply for income-qualified households. Second, geothermal heating and cooling: significantly more expensive upfront than solar but eliminates a much larger portion of the bill (geothermal is the heating system, not just an electricity offset). For all-electric or new-construction homes, this combines well with solar. Third, time-of-use rate plans: Evergy Missouri Metro now offers Nights and Weekends rates with a 322 percent peak/off-peak spread. For households that can shift load, the TOU plan alone can produce 15 to 25 percent savings without any solar. The right answer for many Missouri homeowners is efficiency first, then solar with the smaller system that the efficiency improvements enable.
