Creates a new category of "portable solar generation device" (balcony solar) defined as moveable photovoltaic systems connecting through standard 120-volt outlets with maximum output of 1,200 watts (if UL 3700 certified) or 391 watts, exempt from utility interconnection agreements and net metering requirements

Prohibits electric utilities, cities, counties, and landlords from requiring approval, fees, or additional equipment for portable solar devices that meet safety standards; utilities and landlords are not liable for damage caused by these devices

Makes it a per se violation of the Consumer Protection Act (chapter 19.86 RCW) to sell or falsely advertise non-compliant portable solar devices as safe for self-installation

Requires all electric utilities to allow installation of one customer-owned meter-mounted device per customer, with utilities having 90 days to approve or disapprove specific device models and six months to implement the provisions

Prohibits homeowners associations from banning portable solar generation devices on owners' or residents' property, while allowing HOAs to require indemnification for damages caused by installation
