(2) modules fall into Roof Zone 3. All Mounts touching these modules follow RZ3 spans.
(3) modules along the north edge are >25% in Roof Zone 2. All Mounts touching these
modules follow Roof Zone 2 spans.
(2) modules along the east/west edges enter into Zone 2. Mounts touching these
modules follow Roof Zone 2 spans.
(1) module along the south edge is >25% in Roof Zone 2. Mounts touching this module
follow Roof Zone 2 spans.
For the given site conditions, maximum spans and cantilevers are as follows:
In this instance, maximum spans are identical across all Roof Zones. Mounts can be placed a
maximum of (2) rafters apart (24” x 2 = 48” < 65”).
