California lawmakers pass bill to legalize plug-in solar kits

California lawmakers have passed Senate Bill 868, known as the Plug and Play Solar Act, approving plug-in solar kits for residential use. The bill is ready to be signed into law by Governor Gavin Newsom.

The measure would allow kits of up to 1,200 watts to connect to a standard outlet. Residents would only need to complete a simple online registration form. The panels can be placed on a balcony, wall, or backyard, allowing generated electricity to offset household demand without rooftop-solar installation costs or planning-permission processes.

Official figures suggest the systems could save households up to $450 per year. The change could also help renters because the kits do not require permanent changes to a property and can be moved to a new home.

Utah became the first US state to legalize plug-in solar in 2025, followed by eight other states. New York State is also awaiting a governor’s signature, while proposals are pending in seven additional states.

Retail availability remains limited at major stores, although dedicated start-ups are supplying the market. Bright Saver sells plug-in solar panels starting at under $300 and requires a $29 yearly subscription. Plug-in solar has already become popular in Europe, particularly in Germany, and recently became legal in the UK.
