Lodi, CA Solar Energy: Panel Permits (2026)

19 governs small residential rooftop solar systems (10 kW AC or 30 kW thermal or smaller, installed on a single or duplex dwelling). 040, "Solar energy system requirements," sets the substantive standards: all systems must meet applicable health and safety standards imposed by the state, the City of Lodi, its fire department, and its electric utility. Systems that heat water for single-family residences or commercial or swimming pool use must be certified by an accredited listing agency as defined by the California Plumbing and Mechanical Code.

Systems that produce electricity must meet safety and performance standards from the California Electrical Code, the Institute of Electrical and Electronics Engineers, and accredited testing labs such as Underwriters Laboratories, plus applicable Public Utilities Commission safety and reliability rules. 060 requires the applicant to verify, using standard engineering evaluation, that the roof support structure can carry the system's wind, seismic, dead, and live loads, and to verify at the applicant's cost that the existing electrical system, including line, load, ground, bonding wiring, and panel sizing, can safely carry the new photovoltaic load. 070 requires authorization from Lodi Electric Utility to interconnect to the grid before the application goes to the building and safety division. 010(H).
