Yes. Maryland's plug-in solar law, Md. HB 1532, Ch. 353 (2026), has been in effect since July 1, 2026. The law allows one plug-in system up to 1,200 W, plugged into an ordinary outlet.

What the statute says
| Cap | 1,200 W per meter. |
|---|---|
| Systems | One per meter. |
| Utility notification | Required, before you install: wattage, safety certification. |
| Interconnection fees | None: the utility cannot charge an interconnection fee. |
| Local permit | Not addressed by the statute; check with your county or city. |
| Electrician | The statute does not mention one. It says a person "may purchase and install"; we read that as no electrician required at these sizes, an inference from the text, not something the law says outright. Any change to your wiring or outlets is electrician work; the kit needs none. Hoymiles' written warranty document refers to installation by a qualified professional; see the FAQ. |
| HOA | Not preempted: your HOA keeps its say. |
| Landlord | Not preempted: a landlord can refuse. |
| Net metering | Not stated. Size for what you use in daylight either way; a plug-in system is not a net-metering system. |
| Certification named | Every system must be safety-certified by a recognized testing lab; no standard is named. Ours is UL 1741 certified. |
| Our kits | Covered meets the safety rules |
