The City of San Francisco held a meeting on July 4, 2025, focusing on proposed regulations concerning the installation of solar batteries. The session featured discussions from industry representatives who expressed significant concerns regarding the implications of the proposed bulletin on battery safety and installation.
Ben Davis, representing the California Solar and Storage Association, opened the dialogue by emphasizing the safety of solar batteries. He noted that these batteries undergo rigorous testing to ensure they do not pose threats to occupants or property. Davis argued that the proposed requirements could hinder the installation of batteries, which are crucial for providing clean energy during nighttime hours. He highlighted the need for further discussions with the fire marshal to address safety concerns and suggested that a formal rule-making process should be followed to ensure thorough research and accurate code development.
Following Davis, Mark Balvasari from Enphase Energy supported the review of UL 9540A reports, which could allow for reduced spacing requirements for battery installations. He echoed Davis's call for an extension of the comment period to facilitate collaboration with fire commissioners and board members to develop more effective long-term solutions.
The meeting underscored the importance of balancing safety regulations with the need for clean energy solutions. Participants expressed a desire for continued dialogue to refine the proposed regulations and ensure that they are both safe and conducive to the growth of the solar industry in San Francisco. The discussions highlighted the ongoing challenges in integrating renewable energy technologies while maintaining public safety standards.
