MAINE PUBLIC • April 7, 2026
The Maine House and Senate have passed a bill to legalize plug-in solar, something just two other states have done. Also called balcony solar, the panels are a fraction of the size of rooftop solar. They plug into a standard wall outlet, and because their output is minimal, they don't require connection agreements with utility companies. Systems larger than 420 watts will require installation by an electrician. Using plug-in solar to supplement home energy needs could provide up to 20% savings on electricity for the average Maine household, said Rebecca Shultz, senior advocate for climate and clean energy with the Natural Resources Council of Maine. But Schultz says Maine consumers shouldn't try to order the panels online just yet. Federal safety standards still need to catch up.
