Conduit,
wiring systems, and raceways for photovoltaic circuits
shall be located as close as possible to the
ridge or hip or valley and from the hip or valley as
directly as possible to an outside wall to reduce trip
hazards and maximize ventilation opportunities.
Conduit runs between sub arrays and to DC combiner
boxes shall be installed in a manner that minimizes
the total amount of conduit on the roof by
taking the shortest path from the array to the DC
combiner box. The DC combiner boxes shall be
located such that conduit runs are minimized in the
pathways between arrays. DC wiring shall be
installed in metallic conduit or raceways when
located within enclosed spaces in a building. Conduit
shall run along the bottom of load bearing
members.
Ground-mounted photovoltaic arrays shall comply with
Section 605.11 and this section. Setback requirements
shall not apply to ground-mounted, free-standing photovoltaic
arrays. A clear, brush-free area of 10 feet (3048
mm) shall be required for ground-mounted photovoltaic
arrays.
Stationary storage battery systems having an
electrolyte capacity of more than 50 gallons (189 L) for
flooded lead-acid, nickel cadmium (Ni-Cd) and valve-regulated
lead-acid (VRLA), or more than 1,000 pounds (454
kg) for lithium-ion and lithium metal polymer, used for
facility standby power, emergency power or uninterruptible
power supplies shall comply with this section and Table

beyond that which would normally be
required for human occupancy of the space in
accordance with the California Mechanical
Code.
Where VRLA batteries are
installed inside a cabinet, the cabinet shall be approved for use in occupied spaces and shall be mechanically or naturally
vented by one of the following methods:
- The cabinet ventilation shall limit the maximum concentration of hydrogen to 1 percent of the total volume of the cabinet during the worst-case event of simultaneous "boost" charging of all the batteries in the cabinet.
- Where calculations are not available to substantiate the ventilation rate, continuous ventilation shall be provided at a rate of not less than 1 cubic foot per minute per square foot [1 ft3/min/ft2 or 0.0051 m3/(s • m2)] of floor area covered by the cabinet. The room in which the cabinet is installed shall be ventilated as required in Section 608.6.1.
