A solar energy system that is no larger than ten (10) kilowatts alternating current nameplate rating or thirty (30) kilowatts thermal. B. A solar energy system that conforms to all applicable state fire, structural, electrical, and other building codes as adopted or amended by the city, and all state and city health and safety standards.

Full Breakdown
020 defines a "small residential rooftop solar energy system" for permitting purposes as a system no larger than ten kilowatts alternating current nameplate rating or thirty kilowatts thermal, installed on a single or two-family dwelling, conforming to applicable state fire, structural and electrical codes as adopted by the city, and not exceeding the city's maximum legal building height. 030 applies these rules to all small residential rooftop solar permits citywide, but exempts systems legally established or permitted before the chapter's effective date unless the owner later makes a physical modification that materially changes the system's size, type or components; routine operation and maintenance never triggers new permitting.
040 requires water-heating and pool-heating solar systems to carry certification from an accredited listing agency under the California Plumbing and Mechanical Codes, while photovoltaic systems must meet California Electrical Code, IEEE, and testing-laboratory standards such as Underwriters Laboratories, plus applicable Public Utilities Commission safety and reliability rules. 070.
Violations & Fines
A system that exceeds the 10 kW AC / 30 kW thermal cap, sits on a building other than a one- or two-family dwelling, or exceeds the city's maximum building height does not qualify for the expedited review pathway and must go through standard permitting instead of the priority-review track. Systems lacking required listing-agency or testing-laboratory certification under § 7.96.040 will not clear plan review.
