Do I need utility permission in Maryland?

It depends on your state's rules and your utility. The safe path in Maryland is to use a UL-listed (UL 3700) microinverter and check your utility's interconnection policy (major utilities here include Pepco, BGE) before you install; see the status for Maryland above for specifics.

Maryland now has a plug-in solar law. HB 1532, the Utility RELIEF Act, signed by Gov. Wes Moore on May 12, 2026, took effect immediately under an emergency clause. It allows plug-in systems up to 1,200W, permits one portable solar system per residential meter, and requires UL certification or an equivalent safety standard. Residential power mostly comes from BGE and Pepco; before buying, confirm their interconnection or notification steps, stay within the wattage rules, and choose a UL-listed kit.

Before you buy in Maryland

Call your electric utility and ask: (1) do they allow small plug-in / behind-the-meter grid-tied solar, and (2) is any notification or interconnection form required? Stay within the wattage they specify, use a UL-listed microinverter, and keep written confirmation.

Then estimate your numbers with our savings calculator (pre-loaded with Maryland's rate).
