A racking system application should be suitable for the rooftop pitch and material and the
distance of the PV rack above the roof surface.
The racking system must be installed according to manufacturer installation instructions.
ESS.
Particularly important in California, the ESS must meet weight and seismic design criteria (SDC).
Of the SDC ratings (A-E), most of California is a Category D or E, both of which require seismic
considerations.
ESS must weigh less than 400 lbs., be positively attached to the structure, and be mounted with
the center of gravity less than 4 ft. above the deck (per ASCE 7-16 Chapter 13).
ESS disconnecting means.
The project developer is responsible for any additional ESS disconnecting means required by the
code, that is, line of sight or conductors passing through a wall or partition.
