Concepts
This chapter contains important information on the rules governing Zep Compatible array layouts.
4.1 Drop-In Direction
The PV module drop-in process is specific to Zep Solar hardware designs.
North-South.
Roof attachments run along the vertical rafters. Modules are “dropped in” row by
row going upwards, beginning at the Array Skirt, which is nearest to the eave.
NOTE:
East-West drop-ins, with the Array Skirt to one side, are not supported for ZS
Comp, except in the rare case where the roof is supported by horizontal purlins
instead of vertical rafters.
Is There a Preferred Portait or Landscape Orientation?
ZS Comp can be installed in either
Landscape or Portrait orientation. A Landscape orientation will generally maximize spans in the
East-West direction.
