Plug-in solar rules in Maryland

Is plug-in solar allowed in Maryland?

Yes. HB 1532 (2026 Laws ch. 353), Public Utilities § 7-321 has applied since July 1, 2026.

How much power can I connect?

Up to 1,200 W of inverter output per meter.

What do I need to do?

Check these requirements before you connect a kit.

• Certified by UL or an equivalent nationally recognized testing laboratory. Kits of 391 W or less are exempt from listing provisions that would require rewiring.
• You must notify the utility before connecting.

Can a landlord or HOA stop me?

Renters have no specific protection. Homeowners associations (HOAs) can set their own rules.

Will I be paid for power I export?

No. There is no payment for power sent to the grid, so savings come from the electricity you use yourself.

Other details

Before installation, notify your electric company and give it a certification of the kit's safety features and maximum capacity.
