California lawmakers have advanced a measure that would allow residents across the state to lower their electricity bills by purchasing small solar panel kits and plugging them directly into standard wall outlets. Senate Bill 868 passed through the state Assembly and Senate, clearing the legislative hurdles and moving to the desk of Governor Gavin Newsom. If signed into law, the measure would take effect on January 1, 2027.
California Lawmakers Pass Landmark Plug-In Solar Legislation
Introduced in January by state Senator Scott Wiener, the legislation addresses soaring electricity costs in the nation’s most populous state. The portable systems, commonly referred to as balcony solar, can be placed on a roof, hung off a balcony, or set up in a backyard. Depending on size and components, models generally range in price from $300 to $2,200.
Requirements and Technical Standards for Balcony Systems
To qualify under the newly passed legislation, plug-in solar devices must adhere to specific technical and safety guidelines. Systems are capped at generating 1,200 watts per home and must be utilized exclusively to offset a customer’s onsite electricity consumption rather than feeding excess power back to the electrical grid. Additionally, the devices must be certified by Underwriters Laboratories or an equivalent nationally recognized testing laboratory, and they must meet the standards of the most recent versions of the National Electrical Code and the California Electrical Code.
Supporters emphasize that the technology eliminates the complex red tape typically associated with traditional solar installations. Prior to the legislation, Californians installing plug-in solar panels were often asked by utilities to complete an interconnection agreement. For instance, processes through Pacific Gas & Electric Co. (PG&E) could cost between $100 and $800, take about an hour to initiate, and require roughly three days for approval.
Exemptions, Utility Concerns, and the 2030 Provision
Under SB 868, users of verified plug-in devices would be exempt from filing interconnection agreements or obtaining permission from their local utility, though utilities retain the right to require customers to notify them of their intent to use a plug-in solar device. However, the text of the bill was amended to include a strict timeline regarding this exemption.
The legislation includes a provision that removes the interconnection exemption and user rights to install the systems without utility permission as of January 1, 2030. This change served as a concession to Pacific Gas & Electric Co., the state’s largest utility, which opposed the law over concerns regarding potential impacts on the electrical system. While expressing support for plug-in solar conceptually, PG&E stated that customers deserve protections from clear safety standards and established interconnection processes from the outset. Kevin Chou, cofounder and executive director of the Bay Area nonprofit Bright Saver, noted his expectation that lawmakers will eventually work to remove the 2030 expiration provision as the market grows.
Financial Impact for Renters and Homeowners
Environmental and consumer advocates highlight the potential savings for both homeowners and apartment renters who otherwise lack the infrastructure for rooftop solar arrays.
The legislation has garnered backing from numerous prominent climate and energy organizations, including the Environmental Working Group, Advanced Energy United, The Sierra Club, Vote Solar, and Bright Saver.
If enacted, California would join a growing wave of states authorizing the technology, opening a major commercial market for manufacturers and expanding energy affordability options for everyday consumers.
