Missouri's Solar Reality in 2026
Missouri is one of the least solar-friendly states in the country when it comes to financial incentives. Here's what's gone:
- Property tax exemption, struck down by the Missouri Supreme Court in 2022 and remains legally unenforceable statewide
- Sales tax exemption, Missouri does not exempt solar equipment from the state sales tax
- Ameren Missouri rebate ($0.25/W), ended 2023
- Liberty Utilities rebate ($0.25/W), ended 2023
- PACE financing, prohibited in Missouri effective August 2024
- Federal ITC (Section 25D), expired December 31, 2025
- Net metering (Evergy territory), retail rate monthly netting for Kansas City metro homeowners
- Columbia Water & Light rebate, $500/kW for Columbia city utility customers
- HOA protections, RSMo 442.404 prohibits HOA solar bans
- Long-term bill savings, solar still reduces electricity costs over time, even without incentives
Net Metering: It Depends Heavily on Your Utility
Missouri mandates net metering (RSMo 386.890) for systems up to 100 kW, but the compensation rate is set by each utility. This creates a two-tier Missouri solar market where your zip code determines your economics.
| Utility | Service Area | Excess Generation Rate | Rating |
|---|---|---|---|
| Evergy Missouri West | Kansas City metro, NW Missouri | Billing-period netting; net excess at avoided fuel cost | Best in MO |
| Ameren Missouri | St. Louis, central/eastern MO | ~3.84¢/kWh summer / ~3.39¢/kWh winter (avoided fuel cost) | Worst in MO |
| Liberty Utilities | Joplin area, SW Missouri | Retail rate (historically); verify current tariff | Check tariff |
| Electric Co-ops | Rural Missouri | Varies by co-op; often avoided cost or flat buyback | Check with co-op |
If you're in Ameren Missouri territory (St. Louis and most of central/eastern Missouri), excess solar generation earns only ~3.84¢/kWh in summer and ~3.39¢/kWh in winter, while you pay ~14¢/kWh at retail. Oversizing your system to export power is highly uneconomical. Size your system to cover 85 to 90% of annual consumption with minimal export. Every kWh you self-consume avoids 14¢; net excess beyond your monthly usage earns only about 3.4 to 3.8¢.
If you're in Evergy territory (Kansas City metro), you benefit from retail-rate monthly net metering, a much stronger economic case for solar. Exports offset your usage within each billing period; any net excess for the month is credited at Evergy's avoided-fuel-cost rate, and unused credits expire after 12 months. Evergy also does not have a residential solar rebate program, so the economics rest entirely on energy savings and long-term bill avoidance.
Columbia: The Exception
Columbia's municipal utility, Columbia Water & Light, offers a $500/kW rebate for residential solar installations. On a 6 kW system, that's $3,000 back. This is the only significant utility incentive remaining in Missouri. Columbia residents also benefit from the utility's net metering program. Contact Columbia Water & Light directly for current funding availability and application requirements.
HOA Protections
Missouri law protects homeowners from HOA bans on solar installations. Under RSMo 442.404, homeowners associations may not prohibit solar energy systems, though they can impose reasonable aesthetic requirements (such as panel placement preferences). If your HOA is blocking a solar installation, cite this statute directly.
Federal Tax Credit (ITC)
The federal residential solar Investment Tax Credit (Section 25D) expired at year-end 2025. Systems installed in 2026 do not qualify for a federal residential credit. No extension has been enacted as of October 2026. Missouri homeowners have no state credit and no federal credit stacking opportunity, financial justification depends entirely on electricity cost savings over the system's 25 to 30 year life.
