California legalizes plug-in balcony solar systems
Starting January 1, qualifying systems up to 1,200 watts can bypass traditional utility interconnection approvals and fees, while safety certification remains mandatory.
Gov. Gavin Newsom signed Senate Bill 868 on September 30, formally legalizing qualifying plug-in balcony solar systems across California, KPBS reported October 1. The law takes effect January 1, 2027, and is intended to make small-scale solar more practical for renters and households that cannot install rooftop arrays.
What it means locally
Qualifying devices may produce no more than 1,200 watts per dwelling, must connect through a receptacle, offset onsite electricity use and include certified protection against feeding power back to the grid during an outage. Utilities may require a simple online registration but may not demand prior approval, interconnection fees or added equipment beyond the device's integrated controls. KPBS reported that some higher-wattage installations may still require an electrician or special outlet, depending on the product and safety standards. The interconnection exemptions expire January 1, 2030, unless lawmakers extend them.
