I am designing a solar photovoltaic system for an existing building in Arcata, CA. The building department's plan check agency is requiring a design load of less than 2% from the pv panelboard to the AC disconnect/meter main service, siting compliance with the 2013 California Energy Code Section 130.5 (c). Seems like this section of the Code is for new construction lighting systems and not solar PV addition. Are the recommended voltage drop limits of the NEC (2% feeders and 3% branch circuits) now mandatory based on this section of the Energy Code? Also, is this now a requirement for all solar PV installations on existing buildings?
