Solar by state › Missouri

Home solar in Missouri

Missouri law requires every utility to offer net metering, but extra solar is credited at as little as the utility's avoided fuel cost and expires after 12 months; a strong 2023 law (upheld in January 2026) stops HOAs from banning rooftop solar.

Net metering Net metering available

The Net Metering and Easy Connection Act (RSMo 386.890) makes every utility, including co-ops and city utilities, offer net metering for systems up to 100 kW. Each month your production first offsets what you use; any extra is credited at least at the utility's avoided fuel cost (a wholesale-level price) on the next bill. Unused credits expire after 12 months or when you leave, with no payout. Utilities can stop adding customers at 5% of peak load, or pause a year's approvals at 1%. Source

Solar credits (SRECs) No market

Missouri's renewable standard has a small solar share, but there is no open SREC market for homeowners.

Taxes

Property tax: Uncertain: RSMo 137.100(10) lists solar systems not held for resale as exempt, but the Missouri Supreme Court (2022) called that exemption unconstitutional; ask your county assessor.
Sales tax: None found: no sales tax exemption for home solar. Source

Solar laws

RSMo 386.890, Net Metering and Easy Connection Act (2022). Requires all utilities to offer net metering up to 100 kW; excess credited at least at avoided fuel cost; credits expire after 12 months. Source
RSMo 442.404 (SB 820, 2022), HOA solar access (2023). Covenants and HOAs cannot ban or limit solar on a roof the owner controls. HOAs may set reasonable placement rules that do not block installation or raise cost or cut efficiency. Source
Eikmeier v. Granite Springs HOA (Mo. Supreme Court) (2026). Held on Jan. 23, 2026 that the HOA solar law also covers covenants written before 2023, and that a ban on street-facing panels was not allowed. Source

Community solar

No state community solar law; some utilities (e.g., Ameren Missouri) run their own subscription programs.

Timeline

2022-08-28 Current version of RSMo 386.890 takes effect

Federal tax credits

The 30% federal tax credit for homeowners who buy solar (Section 25D) ended for systems placed in service after December 31, 2025, so buying no longer earns a federal credit. If you lease or sign a power purchase agreement (PPA), the panels belong to a company that may still claim a business credit under federal deadlines that tighten through 2027. Ask your installer whether that savings is in your price.
