Installation Guide
Step 6: Installing PV Modules to Module Rails
PV Modules are secured to the Module Rails using 1/4” x 3/4” bolts and hardware.
Start with the southern most PV Modules and work in a northern direction.
A. Place a southern most PV Module on the Module Rails. Align the mounting
holes and secure with 1/4” x 3/4” bolts and hardware. Each Module has four
attachment points. Finger-tighten for now. (See Figure 6-1)
B. Continue in this manner to install remaining PV Modules.

CAUTION:
This is a two
person activity. PV
Modules are
heavy and
unstable before
they are fully
secured to the
Module Rails. PV
Modules must be
held in place by
one person while
the second person
aligns and
secures them to
the Module Rails.
Failure to do so
could lead to
serious personal
injury and
damaged
components.
