7. COMPLETE BONDING (CONTINUED)
B. ROW-TO-ROW BONDING
The 38" Bonding Jumper is an electrial bonding jumper
that should be used for row to row bonding by securing
Clips to inner flanges on long side of a module from each
row, as shown. Tapping Clips into place may be required
for modules with thicker flanges.
➢
The bonding does not need to take place on the same side of the
array, so long as every row is bonded to the next row.
Ground each continuous array by securing a PV Module
Grounding Lug to any module in the array.
➢
Only one PV Module Grounding Lug is required per continuous
array, regardless of array size. Reference module manufacturer’s
installation instructions for grounding location.
