Missouri Solar Resources 2026: Net Metering, Tax Credits, Grants & Financing

Updated October 29, 2026. Programs change often, so check each link before you sign anything.

Federal tax credits

• Residential credit (25D): ended. It isn't available for expenditures made after December 31, 2025, and an expenditure counts as made when installation is completed. IRS FAQ
• Home energy efficiency credit (25C): ended for property placed in service after December 31, 2025.
• EV charger credit (30C): ended for property placed in service after June 30, 2026.
• Business/farm credit (48E): solar that begins construction after July 4, 2026 must be placed in service by December 31, 2027 (IRS Notice 2025-42). A federal court vacated that notice's narrower "beginning of construction" test on June 6, 2026, but the statutory dates still apply. Confirm with your tax advisor.

USDA REAP (farms and rural businesses)

Grants are paused until USDA opens a window under its October 2026 rule. Loan guarantees remain available. Under the new rule, you build first, apply with 12 months of data, and the grant covers 25% of cost at most, with no ground-mount solar on cropland. Full details: USDA REAP 2026 Guide.

Net metering and interconnection

Missouri's Net Metering and Easy Connection Act (RSMo 386.890) requires utilities, municipal utilities and co-ops to offer net metering for systems of 100 kW or less. Excess generation is credited at avoided cost.

• Ameren Missouri: excess credit of 3.84¢/kWh June–September and 3.39¢/kWh October–May. Since June 1, 2026, net metering customers can choose any residential rate, including time-of-use. Ameren solar · Our Ameren guide
• Evergy: credited at the avoided fuel cost rate, and credits expire after 12 months. Our Evergy guide
• Columbia Water & Light: rebate of $500/kW plus a performance amount, with pre-approval required. Systems are sized to 110% of 3-year average usage, and there's a solar loan program. CWL solar · Our CWL guide

• Co-ops (Boone Electric, Three Rivers, Callaway, CMEC): you need an interconnection agreement before connecting. Boone Electric guide · Mid-Missouri co-op guide

Property tax

The Missouri Supreme Court struck down the solar property tax exemption in RSMo 137.100 in 2022 (Johnson v. Springfield Solar 1). The State Tax Commission says assessors may treat rooftop panels on a home as a fixture that adds to the home's overall value. Statute · STC guidance

Financing

• Commercial and agricultural PACE: the Missouri Clean Energy District finances up to 100% of eligible project costs, repaid through a property tax assessment over 20+ years. Rooftop solar that conveys with the parcel is eligible. MCED
