Is plug-in solar legal in Pennsylvania?
Bill moving Not yet. A bill (HB 1971) is still moving in Pennsylvania.
Introduced Oct 2025; the 2025–26 session ends Nov 30, 2026. 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. Pennsylvania’s bill is HB 1971. We update this page when anything changes.
