California legalizes balcony solar via new legislation

Twelve U.S. states have recently passed or are considering legislation to authorize the use of balcony or plug-in solar systems. These small, affordable panels can be hung from porches or balconies and plugged directly into standard wall outlets, offering a low-barrier way for renters and apartment dwellers to access clean energy.

California has become the tenth state to legalize these systems following Governor Gavin Newsom signing Senate Bill 868, known as the Plug and Play Solar Act. The law removes regulatory hurdles by eliminating the requirement for utility interconnection agreements or advance approval for qualifying devices. To ensure safety, the systems must comply with electrical codes, be certified by testing labs like Underwriters Laboratories, and include protections to prevent feeding electricity back into the grid during outages.

While proponents argue these systems ease the strain on the electrical grid and reduce utility bills, experts note that industry safety standards are still catching up to the technology. Utilities have expressed concerns regarding unregistered systems potentially affecting power flows or endangering workers, though work is underway to establish formal industry guidelines.
