INSTALLATION GUIDE
ARRAY LAYOUT
• Refer to span tables, local jurisdiction, or engineer of record specifications when determining
setbacks from roof edges, attachment spans, etc.
• Mark the perimeter and corners of the array on the roof surface.
*Add 3/4” to account for the gap between modules in each direction*
• Draw or snap chalk lines where the rails will be installed,(refer to module manufacturer specs
to determine allowable mounting locations).
• Locate rafters within the area of the array. It may be necessary to shift
the array East or West on the roof in order to fall within the rail cantilever
specs (1/ 3 of span).
• Stagger rafters every row if required by the local jurisdiction, engineer of record, or company
policy.
