Maryland signed HB 1532 on May 12, 2026. Its plug-in solar section is now in force. Unlike some states, it asks you to tell your utility first. This guide is as of October 2026. It is not legal advice, so check your utility's page before you buy.
Is balcony solar legal in Maryland now?
Yes. HB 1532 became Chapter 353 of the 2026 laws. The plug-in section is new Public Utilities Article 7-321. It appears to have taken effect July 1, 2026. We could not tell for sure from the text, but both possible dates have passed. For other states, see which states allow balcony solar.
How many watts can I plug in in Maryland?
Up to 1,200 watts back to the building's electric system. You may have one system per electric meter, and it is for home use only. The device must be movable and plug into a standard outlet. Its job is to offset what the building uses. It does not count toward Maryland's clean energy goals.
Do I need to tell my utility in Maryland?
Yes. You must notify your electric company before you install. You must also send it a certification of the device's safety features and its top output. If the utility needs an automatic locking disconnect switch, you pay to install it. The utility cannot require approval. It cannot charge a fee for the system's ability to feed power back.
Can my landlord or HOA say no to balcony solar in Maryland?
The law does not stop them. Section 7-321 has no renter, landlord or HOA rules. One website says HOAs cannot ban the devices, but we did not find that in the law. Renters should get written permission first. Read our renters guide for a checklist.
Do I get paid for power I send to the grid in Maryland?
No. These systems are exempt from Maryland's net metering rules, so there is no credit for extra power. Think of it as a way to use less power from the grid. Our savings guide shows how to estimate that for your home.
What does a balcony solar kit need in Maryland?
It must be certified by Underwriters Laboratories (UL) or an equivalent national testing lab. The law does not name a particular UL standard. Devices of 391 watts or less get relief from listing rules that would force changes to your home's wiring or panel. Check the kits sold in the US.
What can I do in Maryland today?
Homeowners, and renters with a landlord's okay, can install one certified system per meter. First, read what balcony solar is and check your sun. Then tell your utility and send the safety certification. Do this before you plug in. Keep a copy of the paperwork.
