Legal · in effect since July 29, 2026Is plug-in solar legal in Maine?
Yes. Maine's plug-in solar law, 35-A M.R.S. § 3475 (PL 2025, c. 644), has been in effect since July 29, 2026. The law allows one plug-in system up to 1,200 W of AC inverter output, plugged into an ordinary outlet. You need an electrician above 420 W (both kits run 391 W). The system must be certified to UL 3700 or a similar safety standard, or be set up to the National Electrical Code.
What the statute says
| Cap | 1,200 W of AC inverter output. |
|---|---|
| Systems | Counted per service address. |
| Utility notification | Required, within 30 days after you install: service address, inverter capacity, a compliance statement (above 420 W). |
| Interconnection fees | None: the utility cannot charge an interconnection fee. |
| Local permit | The statute does not settle it. Check with your county or city before you mount anything. |
| Electrician | Required above 420 W: both kits run 391 W. |
| HOA | Not preempted: your HOA keeps its say. |
| Landlord | Not preempted: a landlord can refuse. Maine's renter protection covers clotheslines only, and a tenant must restore the structure when the panel comes down. |
| Net metering | Not eligible: power you export earns nothing, so size for what you use in daylight. |
| Certification named | UL 3700, or a comparable path. |
| Our kits | Unresolved alternative compliance unresolved |
