3.4 Place Mounts
It is important to note that Mount spacing may be different on the south edge versus the north
edge of a module based on Roof Zone. Therefore, it is important to make sure that RZs are
properly determined prior to placing the mounts.
Starting with the first row of modules, work your way left to right across the row, and then up the
roof applying the Roof Zone Rules (3.4.1) until all Mounts have been placed.
Use the maximum cantilever (S
max
/3) when placing the first Mount, then use the maximum span
(S
max
) to place the next Mount.
