Maine Plug-In Solar Laws
By Daniel Okafor · Last reviewed Maine is classified as effective framework. Confirm implementation guidance with serving utility. The tracked limit is 1,200 W; confirm the final law, exact product and serving-utility process before connection.
Current status
Effective framework
A specific statewide route is in force for qualifying devices. Verify the exact system, site, circuit and serving-utility process before connection.

Framework status and exact product eligibility are separate checks.
What this means today
Maine's LD 1730 became Public Law 2025, chapter 644 and was effective on July 15, 2026, the dataset verification date. The enacted route is available now, but utility implementation can lag a new law. Obtain the serving utility's current instructions before ordering or energising equipment.
The tracked ceiling is 1,200 W. Maine snow, wind, freeze-thaw and coastal exposure make manufacturer-approved mounting important. Preserve guardrail and escape functions, and do not assume exported energy earns credit. A smaller array matched to daytime load may be more useful than the legal maximum.
What LD 1730 says
The Maine Legislature records LD 1730 as enacted and signed April 6, 2026, adding 35-A MRSA §3475 for small plug-in solar generation devices.

Pre-purchase checklist
- 1Confirm continuous inverter AC output is no more than 1,200 W; panel DC nameplate watts are a different measurement.
- 2Ask the serving utility for its current Maine notice, registration, metering and export procedure.
- 3Verify complete-system safety evidence, anti-islanding, plug and branch-circuit requirements; a listed component is not a listed system.
- 4Obtain landlord or HOA consent and check local electrical, planning, fire and structural rules.
- 5Use mounting rated for the site's snow and wind exposure.

Frequently asked questions
Can I use plug-in solar in Maine today?
Maine has an effective statewide framework for qualifying devices. Product, electrical, property and utility conditions still need checking.
Does the watt limit refer to panel watts?
Do not assume so. Compare the final law’s definition with continuous inverter AC output; panel DC nameplate capacity is a different figure.
Will exported electricity be credited?
No export payment or retail credit is assumed here. Ask the serving utility how the meter treats surplus generation and size around daytime self-consumption.
Does a compliant product remove landlord or HOA rules?
No. State energy rules do not grant permission to alter a rented home, common property, balcony rail or façade. Obtain written consent and check local requirements.
Is system-level UL 3700 certification verified for these products?
No product is presented here as having verified system-level UL 3700 evidence. Confirm the precise complete-system listing and all conditions before purchase.
