Is plug-in solar legal in Missouri?
Bill stalled until 2027 Not yet. Missouri's 2026 bill (HB 2528 / HB 2444) didn't pass; supporters expect to try again in the 2027 session.
Without a dedicated law, a kit that sends power into your home wiring counts as a grid connection under your utility’s rules for rooftop solar. That usually means an interconnection application, and some utilities charge fees or require a licensed installer.
What you can do today:
- Ask your utility whether it has a simplified process for systems under 1,000 W. A few do.
- Use solar without touching the grid: a power station charged by portable panels is legal everywhere, including in a rental.
- Watch the bill. Missouri’s bill is HB 2528 / HB 2444. We update this page when anything changes.
