Mount Solar Modules on Rails
• To center the modules on the rails, calculate the amount of excess Module
Mounting Rail length:
1) Add the width of the modules plus 1/2-inch space between modules.
2) For TTP-2: subtract the above calculated number from 85-inches.
For TTP-3 subtract the above calculated number from 127.5-inches.
3) Th
is will give you the total excess length of the Module Mounting Rails.
• Start module installation at the bottom. To center the column of modules on
the rails, place the fi rst two Module Clamps on the rails 1/2 of the total excess
rail length from the bottom of the rails. Be sure to put the side of the top
clamp with the two bonding pins inward toward the module frame.
• Center the fi rst module east to west over the rails and hold in place. Make sure
that the module is straight and level on the rails and tighten the two end clamp
bolts to 108 inch-pounds (9 foot-pounds).
• Install one Module Clamp in each rail on the other side of the fi rst module
and slide it down so that the inside of the clamp contacts the frame of the fi rst
module. Th
e springs will hold the clamps in place prior to tightening. Place
the second module on the rails, align it with the fi rst module, and slide down
and fully into the two mid-clamps. Tighten the mid-clamp bolts to 144 inch-
pounds (12 foot-pounds) to fully secure the module. Install the third module
on TTP-3 in the same manor.
• On the top edge of the last module of the fi rst column, install the Module
Clamps so that the sides with the two stainless-steel pins are facing in toward
the module frame, and the clamp is tight up against the module frame.
Tighten the two end clamp bolts to 108 inch-pounds (9 foot-pounds).
Final Assembly
• Set the array tilt to the desired angle and tighten the Tilt Adjuster bolt to 40 ft -lbs.
• Tighten the U-bolt on the Tilt Adjuster to 20 ft -lbs.
• Rotate the array to point in the desired direction. Tighten the 3/4-inch nuts on the Pole Cap to 100 ft -lbs.
• Tighten all of the 1/2-inch set screws on the Pole Cap to 40 ft -lbs with a 3/4-inch socket.
