Solar Installers in St. Louis: local context
St. Louis has hot summers, cold winters, clay soils and a large stock of older brick homes with basements; parts of the region also have karst limestone terrain.
St. Louis gets moderate sunshine. Solar can still make sense here, but production estimates should be based on your own roof's orientation, pitch and shading rather than regional averages.
The federal residential clean energy tax credit ended for systems installed after December 31, 2025, so do not build your numbers around it. Ask installers to show payback using only incentives that are currently available, and get your utility's net-metering or export terms in writing. Ask about hail ratings on panels and snow load and snow shedding as well.
Licensing and permit rules differ by state and city. Check with Missouri licensing authorities and the local building or permitting office for what applies to your project.
Questions to ask before you hire
- What production estimate do you expect for my roof, and how was it calculated?
- What payback do you show without any expired incentives?
- What are my utility's net-metering or export terms?
- What are the panel, inverter and workmanship warranties?
- Are you licensed for electrical work in this state?
