Temecula, CA Solar Energy: Panel Permits (2026)

4(A) specifically for photovoltaic systems installed in Temecula. Only entities holding a valid A, B, C-10 or C-46 California Contractors State License Board license, or the property owner doing the work personally, may install a solar photovoltaic system, and the applicant must submit valid copies of both the contractor's City of Temecula business license and the CSLB license on the plans before the permit can move forward. The same amendment requires every source of energy in the system, meaning alternating current, solar, wind, battery or fuel cell conductors, to be designed so the current-carrying conductors de-energize and stay de-energized when the utility main breaker is switched off, with the de-energization point located immediately adjacent to the point of energy generation or to the combiner box if one is installed; this applies to every electrical installation regardless of whether the conductors run inside or outside a structure.

On the structural side, the applicant must submit foundation and footing size plans along with substantiating design calculations showing the supporting member sizes, dimensions, materials and imposed loads, though that structural calculation requirement is waived where the module or array's supporting framework is already part of a laboratory-approved listed system. 100.
