California’s legislature approved SB 868, known as the Plug and Play Solar Act, in a move aimed at removing some of the regulatory procedures that hinder the installation of small solar systems that can be connected directly to an electrical outlet. If the required procedures are completed and Governor Gavin Newsom signs the bill, homeowners and renters will be able to purchase and install these systems without first obtaining an interconnection agreement with a utility.
The vote does not yet constitute an effective law. The bill awaits Senate approval of the amendments introduced by the Assembly before being sent to the governor, who has 30 days to act on it. The text also includes a provision ending the interconnection-agreement exemption on January 1, 2030, a condition requested by utilities. According to the bill’s supporters, this provides a four-year transition period to evaluate the market, while allowing the legislature to later repeal the expiration date.
What will change in practice?
“Balcony solar” systems consist of small, portable panels that can be plugged into a standard electrical outlet to reduce the amount of electricity drawn from the grid. SB 868 seeks to expand their availability in apartments, housing units, and single-family homes, while retaining specific technical and safety restrictions.
The bill caps system size at 1,200 watts, a level that, according to the article, is sufficient to power everyday devices such as refrigerators, lighting, Wi-Fi routers, and air-conditioning units. The systems must also be certified by UL or an equivalent national laboratory and must shut down automatically within seconds of a grid outage, to protect utility workers and reduce electrical risks.
Why does this matter?
Environmental Working Group (EWG), which is sponsoring the bill alongside Abundance Network, says that removing interconnection requirements could reduce a time and financial barrier for consumers, particularly renters and low-income households. The organization cites that a 400-watt system could cover about 14% of the consumption of an average apartment, with annual savings of approximately $250. These systems currently start at around $500, while EWG expects broader market adoption to reduce costs.
The push for these systems is also linked to rising cooling costs during heat waves. EWG says that the number of dangerous heat days in California has increased by 55% statewide, and that high electricity bills limit millions of residents’ ability to operate air conditioners. However, these figures and estimates come from the bill’s supporting organization and alone do not establish the actual scale of the impact after implementation.
Context and unresolved limitations
Balcony systems are widespread in Europe, with the article indicating that more than 4 million systems have been installed in Germany. In the United States, Utah preceded California in removing similar barriers in 2025, while eight other states also passed laws in the same direction; a similar bill in New York had also been presented to the governor.
The most important change in SB 868 is the simplification of access to the grid, not the creation of a financial support program or a guarantee of uniform savings for every home. Newsom’s signature, how certification and automatic-shutdown standards are implemented, and the fate of the exemption after 2030 will remain decisive in determining whether the bill turns the technology from a limited option into a broad market in California.
