California Formally Legalizes Smaller, Cheaper 'Balcony Solar' Panels
The law lets renters and homeowners plug 1,200-watt panels into wall outlets, and supporters say it could cut electric bills for people without rooftops.
On Wednesday, Governor Gavin Newsom signed the Plug and Play Solar Act, allowing California residents to install balcony solar panels without navigating complex utility interconnection processes.
Current regulations require lengthy interconnection agreements; Pacific Gas & Electric representatives said the process costs up to $800 and takes days to complete.
Approved systems must generate no more than 1,200 watts and be certified by safety organizations like UL Solutions. Proponents estimate the technology can meet 20% of a home's electricity needs, saving up to $500 annually.
Implementation begins in 2027, though the law sunsets January 1, 2030. Investor-owned utilities PG&E and SDG&E opposed the measure, citing safety concerns and potential cost-shifting to non-solar customers.
Newsom also signed complementary legislation—SB 905 and SB 913—designed to optimize grid infrastructure and support virtual power plants, aiming to curb California's rising electricity bills.
