Step 4: Installing PV Modules to Module Rails
Step 5: Now go back and tighten mounting hardware.
Step 6: Adjust the Tilt Angle of the Rack
PV Modules are secured to the Module Rails using 1/4” x 3/4” bolts and hardware.
A. Place the 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 4-1)
B. Continue in this manner and install the second PV Module.
A. Return and tighten each set of the 3/8” mounting hardware securing the
Module Rails to the Support Angles.
B. Return and tighten each set of 1/4” mounting hardware securing the PV
Modules to the Module rails.
To Adjust the tilt angle, loosen the Pivot Bolt hardware and remove the Support
Arm upper hardware attaching the Support Arm to the Strongback. Use great care in
this procedure as it can be dangerous if the procedure is not completed as described
with a minimum of two people.
A. While one person holds the south edge of rack, the other loosens the Pivot
Bolt and removes the upper 3/8” hardware attaching the Support Bar to the
Strongback.
B. Tilt the rack to the desired elevation angle (15°, 25°, 35°, 45°, 55° or 65°)
and re-attach the Support Bar to the Strongback placing the 3/8” hardware in
the appropriate hole matching the desired elevation.
C. Re-Tighten the Pivot Bolt.
Torque all at 32-34 ft.-lbs.
Torque all at 6-8 ft.-lbs.
Torque to 32-34 ft.-lbs.
Torque to 75-85 ft.-lbs.

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.
CAUTION:
Be certain to
re-tighten all
Module Rail and
PV Module
mounting
hardware and
torque to the
specified values.
Failure to do so
could lead to
structural failure,
damaged
components
and/or serious
personal injury.
