Installation Guide

Next, install the inboard Module Rails
A. Referring to Figure 3-1 for orientation of the outboard Module Rails,
position the Module Rail aligning the mounting holes with the holes of the
Strongback mounting angles and secure with 3/8” x 1” bolts and hardware
. Finger-tighten for now. (See
Figure 3-3)
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. This
provides a measure of safety as the previously installed southern Modules can help
to hold the next in-line northern Module in place during installation.
A. Place the southern most PV Module in place 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.
B. Continue in this manner to install all southern most PV Modules first and
then work in a northern direction installing the remaining Modules.
;
each Module Rail has two attachment points
B. Now install the opposite inboard Module Rail following the above
procedure. Refer to Figure 3-1 as needed for orientation of the Module Rail.
(See Figure 4-1)

Figure 3-3: Installing Inboard Module Rails to the Strongback
NOTE:
Double check the
orientation of
inboard to
outboard Module
Rails. If they are
installed differently
from these
instructions, the
mounting holes
will not align to the
holes of the 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.
