APPLICATION:
The GroundTrac® system is designed with a minimum amount of installed footings at greatly reduced
labor. The system integrates with readily available 1-1/2” schedule #40 galvanized water pipe. This
ground mount solution includes virtually everything needed to install modules with vertical posts up
to 5’ from rear footing, 30” from front footing. The installer will only need pipe, concrete and basic
construction skills to complete the installation. This fully engineered system utilizes Professional Solar
Products’ patented Slide-n-Clamp™ module clamps and support rail.
WARNING:
All ProSolar® products are engineered and tested to withstand
stated specifications (as stated on published engineering
documents) when installed properly. Failure to install properly
may decrease the performance of installation.
SAFETY:
All regional safety requirements should be followed when
installing ProSolar® products. All tools and equipment located
on the roof should be secured to avoid falling object hazards. All
equipment/tools should be properly maintained and inspected
prior to use. Any exposed studs should be protectively capped
to avoid injury. This racking system may be used to ground and/
or mount a PV module complying with UL 1703 only when the
specific module frame has been evaluated for grounding and/
or mounting compliance with the included instructions. This
installation manual is intended for use by professional installers
with a working knowledge of construction principles.

Dig footings.
Lateral footing spans listed on page 6.
Front to rear footing spans listed in angle
charts on page 6.
See engineering for general footing
specifications.
(Footing depths may vary depending
on site specific conditions such as
sloped hillsides. Review site specific
requirements with local building
department as necessary.)
Dig footings
To speed up installation it is recommended to use a
12” power auger to dig your footings.
Build grade stake forms
Assemble re-usable ProSolar grade
stakes). Recommend 2”x4” vertical
support. Drill 2” x 4” with 1/2” drill bit
using grade stake as hole template.
Assemble bolt, washer, spacer block
and grade stake and tighten using
9/16” socket. Attach 1”x 4” wooden
horizontal support using 3-1/2” (min.)
C-clamps.
Grade stake kit incudes: 24” threaded
metal stakes, aluminum spacer blocks,
bolts, and washers.

Insert grade stakes and lay horizontal pipe support
Drive grade stakes with sledgehammer beside
each footing and level 1” x 4” supports using string
line/line level or laser level.
Place horizontal 1-1/2” schedule 40 galvanized
pipe with slip-on Hollaender® Tees along 1” x 4”
supports. Adjust C-clamps as necessary to level
pipe. Use pipe wrenches to couple pipe lengths as
necessary.
24” max. pipe overhang from end vertical support
Measure pipe heights and cut
Measure vertical pipe lengths with measuring tape from
bottom of footing to horizontal pipe. Deduct 2” from length
to avoid pipe contact with bottom of footing moisture. Note
measured lengths.
Cut pipe lengths using a chop saw, reciprocating saw, or
portable band saw
Use only 1-1/2” Schedule #40 Galvanized water pipe
(not fence tube) for your supports.
Standard 21’ length water pipe with pre-attached
couplers readily available at plumbing supply houses.

for tips and visual representation.)
1-1/2” Schedule 40 pipe max end overhang of 2 feet.
Attach initial support rails with Drop-N-Lock U-bolt assembly
Rest rail on top of horizontal pipes and insert
U-bolt. Place Drop-N-Lock support rail insert
into the rail and align with U-bolt. Hand tighten
nuts.
U-bolt nuts should be evenly
tightened to avoid u-bolt
misalignment.

FOR GROUNDING CONNECTION
• ILSCO SGB-4 rail ground connection
• Fasten both terminals to 35 in-lbs
• Ensure that copper wire does not touch aluminum;
Recommended ¼” clearance.

of rail.
Outdoor rated, insulated wire, such as quick connect
cables, can be nested inside the RoofTrac®support rail
or held in place with approved cable clip such as Wiley
ACC-R2 ( for Microinverter trunk cable) and ACC-R4
(for PV wire) clips.
Uninsulated copper grounding wire must never be
placed inside the aluminum rail – it should be kept at a
distance of at least ¼” away from the aluminum rail.
