Maryland plug-in solar status

Signed into lawSigned into law
Where Maryland stands: Maryland enacted plug-in solar through HB 1532, the Utility RELIEF Act (Chapter 353), signed by Governor Wes Moore on May 12, 2026. Because the law included an emergency clause, it took effect right away.

The law allows plug-in solar devices up to 1,200 watts. It asks you to notify your utility before installing and to use a device with safety certification — but it exempts the smallest systems, 391 watts or less, from the UL certification requirement.

Utilities cannot require approval before you install a qualifying device, and the law covers renters as well as homeowners.

As always, confirm your local building and fire codes and any landlord or homeowners association (HOA) rules before installing.

Before you buy in Maryland

This page is informational research, not legal advice — and it can fall out of date quickly. Before installing anything, confirm the current law and its start date, any size limit, your local building and fire codes, your utility’s requirements, that the kit is certified as a complete system, your landlord or homeowners association (HOA) rules, a safe way to mount it, and the maker’s instructions.

Estimate your savings in Maryland

Use the calculator to get a rough idea. For a truer number, swap the national average electricity price for your own rate (it’s on your bill), and remember that surplus power you send back may earn nothing unless your state and utility specifically pay for it.

A planning estimate, not a promise. It doesn’t check whether plug-in solar is legal where you live, whether a kit is certified, whether your outlet or mount is suitable, or whether your utility pays for surplus power.
