1. (1) “Energy Commission” means the State Energy Resources Conservation and Development Commission.
2. (2) “Residential energy storage system” means commercially available technology, located behind a customer’s residential utility meter, that is capable of absorbing electricity generated from a colocated electricity generator or from the electrical grid, storing it for a period of time, and thereafter discharging it to meet the energy or power needs of the host customer or for export.
3. (3) “Residential solar energy system” means any configuration of solar energy devices that collects and distributes solar energy for the purpose of generating electricity and that has a single residential interconnection with the electric utility transmission or distribution network.
4. (4) “SolarAPP+” means the most recent version of a web-based portal, developed by the National Renewable Energy Laboratory, that automates plan review, produces code-compliant approvals, and issues permits for residential solar energy systems and residential energy storage systems paired with residential solar energy systems.
(b)
1. (1) Pursuant to the compliance schedule in subdivision (c), a city, county, or city and county, in consultation with the local fire department, district, or authority, shall implement an online, automated permitting platform, such as SolarAPP+, that meets both of the following requirements:

  2. (B) The platform issues permits or allows the city, county, or city and county to issue permits for residential solar energy systems and residential energy storage systems paired with residential solar energy systems that SolarAPP+ is capable of processing.
2. (2) A city, county, or city and county is not required to permit an application for a residential solar energy system or a residential energy storage system paired with a residential solar energy system through the online automated permitting platform pursuant to this section if the system configuration is not eligible for SolarAPP+ at the time the application is submitted to the jurisdiction.
