California Expands Balcony Solar with Plug-and-Play Solar Act

Core Legislation Expands Plug-in Solar Options
Governor Gavin Newsom signed the Plug and Play Solar Act, permitting renters and homeowners to place small “balcony solar” kits on patios, fences or terraces and plug them directly into wall outlets. The law caps generation at 1.2 kilowatts and bars any export of electricity to the grid. Panels must be certified by a nationally recognized testing laboratory (e.g., UL Solutions), and owners only need to notify their utility. The authorization remains in effect through Jan. 1, 2030.
Background and Context
California’s rooftop-solar market has long been dominated by full-size systems that require utility interconnection and landlord approval. A gray-area market for plug-in kits already existed, with some residents purchasing units online despite lacking formal permission. The new law follows similar measures adopted in at least nine other U.S. states and mirrors Germany’s long-standing balcony-solar programs. Since 2025, California has become the tenth state to legalize such systems, while roughly two dozen additional states are reviewing comparable bills.
Official Statements & Responses
Sen. Pacific Gas and Electric Co. (PG&E) lobbied against the act, voicing safety concerns and warning that non-panel owners could end up subsidizing grid maintenance costs.
Criticism & Opposition
PG&E’s opposition centers on two points: (1) the safety of plug-in kits that bypass traditional utility inspections, and the potential for cost-shifting, whereby households without panels might bear a larger share of grid-maintenance expenses. The utility did not comment further when approached for comment after the bill’s passage.
