Thank you for choosing MT Solar Pole Mounts.
It is the installer’s responsibility to determine the foundation parameters based on local site conditions,
such as wind speed, snow load, soil type, exposure category, etc. Installations also must comply with local
building regulations and permitting requirements.
We recommend consulting a licensed engineer to determine appropriate foundation dimensions and pipe
size and thickness. MT Solar can also provide a stamped drawing engineered for site-specific requirements
for an additional fee. Please contact us to find out more.
Tips for Conventional Pipe Installation:
Dig hole according to recommended depth and diameter.
Set pipe in hole and use a level to ensure it is plumb and vertical to the ground.
If installing multiple poles, use a string to line up pipes.
Brace pipe to prevent it from moving while pouring concrete.
Proper compaction of backfill around sonotube or form is recommended, unless pouring so that con-
crete is in direct contact with the soil.
Allow concrete to cure for recommended length of time.

Installation Guide
102 101
101: With the 8" Sch 40 or Sch 80 steel pipe installed in the ground, place the lifting insert
into the top of the pipe until it sits flush.
102: Place the lifting bracket into the lifting insert with the eye facing south.
103: Hang a 1 ton or greater chain fall hoist from the lifting eye.
104: Hang the U-Bracket Assembly on the Chain Hoist.
105 106
105: While holding the U-Bracket around the pole, insert 2 of the 3/4" x 11” bolts through the holes in the
back of the U-bracket and through the holes on the Back Plate with 3/4” flat washers on both sides and
3/4” nuts, but do not tighten.
106: Insert three 3/4” x 3” Set Bolts in Back Plate, but do not tighten if leaving chain fall hoist connected.
Note: If installing multiple mounts with a single hoist, bolt the pole cap on the pole at the desired working
height. Tighten 3/4” bolts and 3/4” set screws to 200 ft-lb. Assemble rack, rails and modules. Then, move
lifting assembly and hoist to pole when ready to lift. Attach to pole cap and loosen bolts. Continue with
raising the array for wiring or completing the installation.

107: Attach the Screw Adjuster to the tab on the Back Plate with the 1/2” x 1 1/2” Bolt, two 1/2” flat
washers and 1/2” Nylock Nut. Make sure the bolt is snug tight, but do not over-tighten to allow for some
movement of the adjuster tab.
108: Slide the 2” pipe through the screw adjuster and slide the 4.5" pipe through the U Bracket Assembly
sleeve.
109
110 A
109: Center pipes in sleeves. There should be approximately 16” of the 4.5” pipe on either side of the
sleeve.
110: Slide collars on 4.5” pipe and tighten 1/2” x 1” square head set bolts to 45 ft lbs. Hold collar firm
against the sleeve when tightening. The nut should be facing out, away from the sleeve.

111: Ensure that the MT Solar lettering is upright, and attach one of the 3x5 rectangular tubes to the 4.5”
pipe using the 3/4” x 5” bolts, large 5” square plates and 3/4” split washers. Attach to the 2” pipe using
the 1/2” x 4 1/2” bolts with 1/2” flat washers and split washers.
112: Install the remaining 5"x3" rectangular tube. Snug up all 4 bolts, but leave loose enough to allow for
some play when installing I-beams. Adjusting the Screw Adjuster as necessary, level the array in prepara-
tion for I-Beam installation.

113: Install center I-beams to the 3x5 tubes using the 3/4" x 2” bolts, 3/4” flat washers & 3/4” split washers.
DO NOT TIGHTEN at this step. Install all I-beams with notches up.
114: Splice the two I-beam wings on the ends of the center beam using the 1/2” x 1 1/4” bolts and 1/2”
flange nuts. The Alignment Set Screws may be used to align the I-Beam Center piece to the I-Beam Wings, if
necessary. Once I-beams are level, make sure all alignment set screws are touching the plate of the I-Beam
wing and tighten the 1/2” bolts to 45 ft lbs.

115: Standing on the North Side of the array with the Tube to Beam bolts started but not tightened,
sight the beams to ensure they are parallel. If not, twist the array until they are. .
116 A
116 B
116: Plan the layout of your rails according to your module manufacturer’s recommendation. Install the
Beam Clamps on the I-beam using the 3/8” x 1 1/4” carriage bolts and 3/8” flange nuts. Tighten to 20 ft
lbs. The TOP-15 uses a long angle-shaped clamp to give extra support to the span and cantilever. Attach
angle using the plates provided and the 3/8” x 1 1/4” carriage bolts and 3/8” flange nuts.
For the 8-TOP-8, remember to leave a 9-10” gap in the center to allow for the 8 5/8” (OD) pipe to protrude
through, if you wish to put all the modules on at ground level.
*For standard array configurations using 60 cell modules (approximately 40” x 65”), see pg 11.
TOP-15 Beam Clamps
Then tighten all the 3/4” bolts between
the Pipe and Rectangular Tubes and the
Tubes and the I-Beams to 100 ft lbs.

119: Install Solar Modules as per Mounting Rail and module manufacturer instructions using top clamps.
See last page of manual for Iron Ridge Rail and Clamp instructions.
118
117: Install the Mounting Rail into the beam clamps slot as per Mounting Rail instructions. Use 3/8” x 1”
stainless steel bolts and 3/8” serrated flange nuts.
118: Center rails over I-beams, keeping equal length of rail off the end of each beam. Tighten to 17 ft lbs.

122: With the mount hanging free on the hoist, FIRST tighten the square-headed set bolts in the back
mounting plate to a minimum of 200 ft-lb. Remove the gap by tightening the set bolts until the front of
the U-Bracket is snug against pipe, then make one more full rotation of the bolt. SECOND, tighten both
11” bolts in back mounting plate to 100 ft-lb. Insert the last 3/4" x 11” bolt over the top of the pole with
the 3/4” flat washers and 3/4” nut. Tighten to 20 ft lbs.
123: Remove the chain hoist and lifting bracket and place the 2” square cap in place.
120: Leave out the appropriate module(s) to allow for the 8” pipe. It is ok to install the top and bottom
modules of the center row(s) with just 2 clamps until the array is lifted to the top. Raise and or tilt the
array to facilitate module installation and/or module wiring and wire management as needed.
121: When wiring is completed, raise the array to the top of the pole.
122B
NO GAP!!
Remove the gap by tightening
the square set bolts until the
front of the U-Bracket is snug
against pipe, then make one
more full rotation of the bolt.

125: Attach adjuster handle using the set screw. You may cut
the handle to length depending on pole height and site condi-
tions. We recommend occasional greasing of the threaded rod.
Using an angle finder, adjust array to proper tilt.
124: Place the final module in the empty space. It may be advan-
tageous to fully extend the Screw Adjuster to make this easier. If
necessary, the lifting bracket can be removed and the array tilted
to 90 degrees. In this position the lifting bracket and chain hoist
can be re-installed and once the bolts are loosened the array can
be lowered down to install the final module.
