Porterville, CA Solar Energy: Panel Permits (2026)

Article V of Chapter 7, adopted by Ordinance 1829 on November 17, 2015, defines a "small residential rooftop solar energy system" in section 7-13 as one no larger than ten kilowatts alternating current nameplate rating or thirty kilowatts thermal, installed on a single- or duplex-family dwelling, conforming to applicable state fire, structural, and electrical codes, and not exceeding the maximum legal building height defined by the city. That size threshold determines whether a project qualifies for the article's expedited review path rather than standard discretionary review.

Substantively, section 7-16 requires every solar energy system to meet applicable health and safety standards imposed by the state and city; water-heating systems, whether for single-family residences or commercial and pool applications, must be certified by an accredited listing agency as defined by the California plumbing and mechanical codes; and electricity-producing systems must meet all applicable codes plus IEEE standards and testing by accredited laboratories such as Underwriters Laboratories, along with any applicable Public Utilities Commission safety and reliability rules. Section 7-13 also caps what a homeowners association can charge to approve a system: no more than 10 percent of system cost (capped at $1,000) for water or pool heating systems, or up to $1,000 over specified cost for photovoltaic systems, before a restriction counts as unreasonably increasing cost.
