Mainers are one step closer to being able to utilize compact, plug‑in solar kits to reduce their household’s energy bill, with the Legislature’s passage last week of LD 1730.
The units require no rooftop construction and can be installed almost anywhere: on the ground, balcony, deck, or on the side of a building.
No approvals will be needed through the utility interconnection process required for larger rooftop systems, though the assistance of a licensed electrician is required.
The legislation received bipartisan support in both the House and Senate and now moves to Gov. Janet Mills, who has final say on the measure.
Plug-in solar has been widely adopted in Europe. The systems have been modified to meet U.S. electrical standards and can be plugged into an outdoor outlet to generate energy on-site.
For the average Maine household, a 1,200-watt plug-in solar system could cut electricity bills by nearly 20% or $388 a year, according to the Office of the Public Advocate.
