New England states are moving to legalize plug‑in solar kits that residents can connect to standard outlets, a move that could lower heating costs for homes that rely on volatile oil and gas.

The push comes amid soaring energy prices and supply shocks that have pushed oil and natural gas prices higher, making heating bills a major concern for New England households.

Maine’s bill is close to final passage and could reach the governor’s desk next week. New Hampshire and Vermont have each passed stand‑alone measures, while Massachusetts and Connecticut have included plug‑in provisions in broader energy bills. Rhode Island’s bill is under study. The kits average $3 per watt, and the cost is expected to fall by about half once at least five states authorize them. Residents could install systems up to 1,200 W without utility approval. The new rules would also require the solar equipment to be certified by a national safety testing organization, such as UL Solutions, which launched a testing program for these systems earlier this year. The technology is already available from major retailers, including Ikea.

Connor Yakaitis, deputy director of the Connecticut League of Conservation Voters, noted that plug‑in solar has gained significant momentum. Cora Stryker, co‑founder of Bright Saver, said the legislation has taken off because people are thrilled about saving money and having power to insulate themselves from rising energy bills. Sam Evans‑Brown, executive director of Clean Energy New Hampshire, added that the bills send a signal that the technology is a viable option worth considering.

If the bills pass, residents could install plug‑in systems without utility approval, potentially reducing heating costs and providing a low‑barrier alternative to rooftop solar. The technology’s affordability and ease of installation could spur broader adoption across the region.
