Innovative. Adaptable. Grounded.
The SFUSA°Ground Mountsystem is the optimal solution for residential
and light commercial solar projects. By custom designing and
manufacturing components in-house, Solar Foundations' structure
fits and functions together seamlessly, installs in for less time and
with greater strength. The highest quality materials such as high-
grade steel fully galvanized in accordance with ASTM standards and
high -strength aluminum alloys for our panel support rails are utilized
for long-term durability. Designed to withstand high snow and wind
areas, the UL 2703 classified system has an expected lifespan that
exceeds multiple panel lifecycles. Thus, Solar Foundations' product
maximizes the residual investment ofyour ground mount structure.
Solar Foundations' patented rail
design offers a simple connection
detail between the panel support rail
and the horizontal support beams.
The patented telescopic design of
the SFUSA Wind Brace allows quick
and easily adaptable length changes
to match installation conditions
where significant adjustability is
required.
A two -man crew can typically install
up to about a 25kW residential
structure in a single day.
SFUSA has developed processes
and equipment that permits the
installation of our patent pending
ground screws in any soil conditions
including solid rock.
:f Allows for mounting panels in
four-, five- or six -high in landscape
orientation and can be adapted to
custom configurations
./ Durable design enables any wind
speed and snow load
10° to 40' tilt with multiple inter -row
spacing options
Compatible with a wide range of
modules

Substructure Assembly
We provide maximum support
for our structure by utilizing
high yield strength hollow
structural steel sections on
our racking systems.
Racking Assembly
Solar Foundations' patented
rail design offers a simple
connection detail between
the panel support rail and
the horizontal support
beams, allowing 6 modules
per column in landscape
orientation.
Our patented telescopic
design allows quick and easily
adaptable length changes to
match installation conditions.
Module End Clamp
Our end clamp design
securely fastens the top and
bottom edges of a column of
solar panels to the SF Rail.
Diagonal Wind Srate
Column Connector
Solar Foundations'hot-dipped
galvanized custom Wind Brace
Column Connectors fasten
the Diagonal Wind Brace to a
vertical column.
Module Mid Clamp
e
The mid clamp fastens two
adjoining solar panels in a
column of solar panels to the
SF Rail. Our sleek design with
multiple serrations increases
the holding power of the
modules to our SF Rails.
Contact us at info@solarfoundationsusa.com or (855) 738-7200.
Column Caps
Our unique design allows a
straightforward connection to
the horizontal steel support
beam.
Grounding
Our UL 2703 Certification
encompasses the rail to beam
and beam to pile connections,
permitting the use of a single
grounding lug for the entire
racking system.

OBTAIN THE REQUIRED INDICATED CAPACITIES AND THE MINIMUM
INSTALLATION DEPTH SHOWN ON THE PLANS SHALL BE
SATISFIED PRIOR TO TERMINATION OF THE GROUND SCREW
INSTALLATION. THE INSTALLATION TORQUE SHALL BE AN
AVERAGE OF THE INSTALLATION TORQUES INDICATED DURING THE
LAST ONE FOOT OF INSTALLATION.
2. THE TORSIONAL STRENGTH RATING OF THE GROUND SCREW
SHALL NOT BE EXCEEDED DURING THE INSTALLATION. IF THE
TORSIONAL STRENGTH LIMIT OF THE GROUND SCREW HAS BEEN
REACHED, BUT THE SCREW HAS NOT REACHED THE -TARGET
DEPTH, PERFORM THE FOLLOWING:
a. REVIEW DEVELOPED TORQUE AND GROUND SCREW DEPTH
WITH ENGINEER OF RECORD TO DETERMINE IF ACCEPTABLE
FOR THIS INSTALLATION BASED UPON MINIMUM FROST DEPTH
REQUIREMENT.
b. FOR INSTALLATION INTO HIGHLY COMPACTED SOIL, CREW
SHALL PRE —DRILL THE GROUND SCREW LOCATION WITH A
311" CARBIDE TIPPED ROCK AUGER TO FULL GROUND
SCREW DEPTH PRIOR TO INSTALLATION OF THE GROUND
SCREW.
c. FOR INSTALLATION INTO SOLID ROCK, CREW SHALL
PRE —DRILL THE GROUND SCREW LOCATION WITH A 3%"
PNEUMATIC DRIVEN ROCK DRILL. DEPTH OF DRILLED HOLE
INTO THE ROCK SHALL BE A MINIMUM OF 30" TO ALLOW
THE GROUND SCREW TO BE INSTALLED A MINIMUM OF 24"
INTO THE ROCK FOR FULL FLIGHT ENGAGEMENT.
3. IF THE TARGET DEPTH IS ACHIEVED, BUT THE TORSIONAL
REQUIREMENT HAS NOT BEEN MET THE INSTALLER PERFORM
ONE OF THE FOLLOWING:
a. INSTALL THE GROUND SCREW DEEPER TO OBTAIN THE
REQUIRED CAPACITY.
b. REMOVE THE GROUND SCREW AND INSTALL AN APPROVED
SINGLE FLIGHT PILE WITH A LARGER DIAMETER HELICAL
PLATE OR ONE WITH MULTIPLE HELICAL PLATES.
c. REDUCE THE LOAD ON THE INDIVIDUAL GROUND SCREWS BY
PROVIDING ADDITIONAL GROUND SCREWS AT A REDUCED
SPACING. CONTACT ENGINEER OF RECORD FOR
DETERMINATION OF MAXIMUM PILE SPACING BASED UPON
DEVELOPED TORQUE.
