Solar in St. Louis: your utility and the rules
Homes in the City of St. Louis are served by Ameren Missouri, an investor owned utility regulated by the Missouri Public Service Commission. Under Missouri's Net Metering and Easy Connection Act, RSMo section 386.890, Ameren nets the electricity you use against the electricity your solar system sends back each billing period, and any excess is credited on the following bill at Ameren's net metering rate, which is based on avoided fuel cost, with credits expiring twelve months after they are issued. Ameren must approve your interconnection application before your system runs connected to the grid, and inside city limits the Building Division Permits Section handles the building and electrical permits for solar.

Common questions in St. Louis
Who is the electric company for solar homes in St. Louis?
Ameren Missouri, an investor owned utility regulated by the Missouri Public Service Commission, serves the greater St. Louis area. Its net metering terms are set in its tariff for electric power purchases from qualified net metering units.
How does Ameren Missouri net metering work?
Each billing period, Ameren nets the electricity you use against the electricity your system sends to the grid. If you send back more than you use, your bill shows a credit at Ameren's net metering rate, which is based on avoided fuel cost, and that credit applies to the following bill and expires twelve months after it is issued. Regular monthly customer charges still apply.
What permits do I need for solar panels in the City of St. Louis?
The City of St. Louis Building Division says solar panel installation requires a building permit, and a licensed electrical contractor must obtain an electrical permit. Ameren asks for the local permit number and approval before it interconnects your system, and homes in historic districts may also need review by the city's Cultural Resources Office.
Is there still a federal tax credit for home solar?
The federal residential clean energy credit, section 25D, ended for home solar expenditures made after December 31, 2025, under the law signed July 4, 2025. The IRS treats the expenditure as made when installation is completed, so a system completed in 2026 does not qualify even if it was paid for earlier.
