Lawmakers elsewhere are now stampeding to make plug-in solar available to their constituents.

Besides Utah and now California, legislatures in more than a dozen states want to unleash the tech: Hawaii, Illinois, Indiana, Maine, Maryland, Missouri, New Hampshire, New Jersey, New York, Pennsylvania, South Carolina, Vermont, Virginia, and Washington have all introduced bills, according to Cora Stryker, co-founder of plug-in solar nonprofit Bright Saver, which has been advising some states on their proposals. Based on conversations the organization has had with state representatives, Stryker said she expects a whopping half of U.S. states to introduce bills this year.

“We should empower people to use this technology,” Wiener said. ​“And right now, it’s too hard. The idea that you have to get an interconnection agreement with the utility to put … plug-in solar on your balcony — it makes no sense.”

“The current permitting process is difficult,” Aaron Gianni, president of Larratt Brothers Plumbing in San Francisco, told state policymakers on Jan. 6. ​“As a contractor dealing with more than 109 different building departments in the Bay Area, we must navigate the nuances of each: different inspectors, changing paperwork requirements, high fees, and strict setbacks [that] sometimes make installation impossible.”

The situation can be even worse when a customer lives in a unit governed by a homeowners association, Gianni said. ​“Many HOAs have outright prevented new electric equipment from being installed.”

Wiener, who’s running for U.S. Rep. Nancy Pelosi’s seat and boasts a tongue-in-cheek MAGA fan club, put it bluntly. Permitting in some cities ​“is way too lengthy and onerous and expensive.”

“The [heat-pump] bill creates a streamlined path to be able to get a quick, automatic permit,” he explained. It would also loosen restrictions on equipment placement, cap permit fees at $200, and make it illegal to ban heat pumps.

The plug-in solar bill has yet to come up for any votes. Still, with energy affordability shaping up to be a decisive issue in the 2026 midterm elections, both proposals ​“have, I think, a real possibility of passing,” Wiener said.

“These technologies are a win-win-win, and enabling access to them is simply good government.”
