Plug-In Solar in Maine
Maine LD 1730 was signed by Governor Janet Mills on April 6, 2026, as Chapter 644, with an effective date on or after July 15, 2026. The law allows plug-in solar devices up to 1,200 watts with tiered installation and utility notification requirements based on system size.

What This Means For You
Strong progress — Maine has passed plug-in solar legislation (LD 1730). However, outlet-connected plug-in systems are not legal until the law's effective date (7/15/2026). Until then, follow existing rules and treat grid-connected plug-in kits as not yet permitted.
Understanding Your Solar Options in Maine
What You Can Use Now: Portable Power Stations
Portable power stations are standalone battery systems that work regardless of plug-in solar rules. Solar panels charge the battery; you plug devices into the station — not into your wall — so you stay off the utility grid until plug-in solar is effective.
What's Next: True Plug-In Solar
After the effective date (7/15/2026), qualifying microinverter kits should become legal to connect to a wall outlet under the new framework — subject to wattage limits and equipment rules in the statute.
The Upgrade Path
Buying panels and a portable station now is still a useful on-ramp. When the law is live, many setups can add a listed microinverter to convert to plug-in operation; keep receipts and check final rules when they are published.
Stay Ready for the Effective Date
Watch for utility guidance or registration steps that sometimes follow signing. We'll keep this page updated as implementation details firm up.
Products Available in Maine
Maine has passed enabling legislation (LD 1730), but plug-in grid connections are not legal until the law's effective date. Until then, portable power stations and off-grid solar accessories are the practical way to use solar at home without utility approval.
