i. Installer's Responsibilities
Please review this manual thoroughly before installing your
SolarMount system.
This manual provides (1) supporting documentation for
building permit applications relating to UniRac's SolarMount
Universal PV Module Mounting system, and (2) planning and
assembly instructions for SolarMount
SolarMount products, when installed in accordance with
this bulletin, will be structurally adequate and will meet the
structural requirements of the IBC 2006, IBC 2003, ASCE 7-
02, ASCE 7-05 and California Building Code 2007 (collectively
referred to as "the Code"). UniRac also provides a limited
warranty on SolarMount products (page 26).
SolarMount is much more than a product.
It's a system of engineered components that can be assembled
into a wide variety of PV mounting structures. With
SolarMount you'll be able to solve virtually any PV mocltile
mounting challenge.
It's also a system of technical support: complete installation
and code compliance documentation, an on-line Sola~Moum
Estimator, person-to-person customer serv/ce, and design
assistance to help you solve the toughest challenges.
Which is why SolarMount is PV's most widely used mou
system.
The installer is solely responsible for:
· Complying with all applicable local or national building codes,
including any that may supersede this manual;
· Ensuring that UniRac and other products are appropriate for
the particular installation and the installation environment;
· Ensuring that the roof, its rafters, connections, and other
structural support members can support the array under all
code level loading conditions (this total building assembly is
referred to as the building structure);
· Using only UniRac parts and installer-supplied parts as
specified by UniRac (substitution of parts may void the
warranty and invalidate the letters of certification in all
UniRac publications);
· Ensuring that lag screws have adequate pullout strength and
shear capacities as installed;
· Verifying the strength of any alternate mounting used in lieu
of the lag screws',
· Maintaining the waterproof integrity of the roof, including
selection of appropriate flashing;
· Ensuring safe installation of all electrical aspects of the PV
array; and
· Ensuring correct and appropriate design parameters are
used in determining the design loading used for design of the
specific installation. Parameters, such as snow loading, wind
speed, exposure and topographic factor should be confirmed
with the local building official or a licensed professional
engineer.
SolarMount UniRac Code-Compliant lnstallation Manual ~N~l~J[~l,~®
Part I. Procedure to Determine the Design Wind Load
[1.1.] Using the Simplified Method - ASCE 7-05
The procedure to determine Design Wind Load is specified
by the American Society of Civil Engineers and referenced in
the International Building Code 2006. For purposes of this
document, the values, equations and procedures used in this
document reference ASCE 7-05, Minimum Design Loads for
Buildings and Other Structures. Please refer to ASCE 7-05 if
you have any questions about the definitions or procedures
presented in this manual. UniRac uses Method 1, the
Simplified Method, for calculating the Design Wind Load for
pressures on components and cladding in this document.
The method described in this document is valid for flush, no
tilt, SolarMount Series applications on either roofs or walls.
Flush is defined as panels parallel to the surface (or with no
more than 3" difference between ends of assembly) with no
more than 10" space between the roof surface, and the bottom
of the PV panels.
This method is not approved tbr open structure calculations.
Applications of these procedures is subject to the following
ASCE 7-05 limitations:
1. The building height must be less than 60 feet, h < 60. See
note for determining h in the next section. For installations
on structures greater than 60 feet, contact your local UniRac
Distributor.
2. The building must be enclosed, not an open or partially
enclosed structure, for example a carport.
3. The building is regular shaped with no unusual geometrical
irregularity in spatial form, for example a geodesic dome.
4. The building is not in an extreme geographic location such
as a narrow canyon or steep cliff.
5. The building has a flat or gable roof with a pitch less than 45
degrees or a hip roof with a pitch less than 27 degrees.
6. If your installation does not conform to these requirements
please contact your local UniRac distributor, a local
professional engineer or UniRac
If your installation is outside the United States or does not
meet all of these limitations, consult a local professional
engineer or your local building authority. Consult ASCE 7-05
for more clarification on the use of Method I. LoWcl tit :;5 I1
wind loads may be obtained by applying Method I1 from ASCE
7-0S. Consult with a licensed engineer if you want to use
Method II procedures.
The equation for determining the Design Wind Load for
components and cladding is:
pn~t Cpsf) = Design Wind Load
A = adjustment factor for height and exposure category
Kzt = Topographic Factor at mean roof height, h (ft)
I = Importance Factor
pnet$O (psf) = net design wind pressure for E~posurc B, at height
=30, I=1
You will also need to know the following information:
Basic Wind Speed - V (mph), the largest 3 second gust of wind in
the last 50years.
h (ft) - total roofheightforfiat roof buildings or alcan roof
height for pitched roof buildings
Effective Wind Area (s f) - minimum total contintlotls cu'erl of
modules being installed
Roof Zone - the area of the roof you are installing thc pr.system
according to Figure 2, page 5.
Roof Zone Setback Length = il (ft)
Roof Pitch (degrees)
Exposure Category
[1.2.] Procedure to Calculate Total Design Wind
The procedure for determining the Design Wind Load can be
broken into steps that include looking up several values in
different tables.
Step 1: Determine Basic Wind Speed, V (mph)
Determine the Basic Wind Speed, V Onph) by consulting your
local building department or locating your installation on the
maps in Figure 1, page 4.
Step 2: Determining Effective Wind Area
Determine the smallest area of continuous modules yocl will
be installing. This is the smallest area tributary (contributing
load) to a support or to a simple-span of rail. That a~ea is the
Effective Wind Area.

Step 3: Determine Roof/q/gall Zone
The Design Wind Load will vary based on where the
installation is located on a roof. Arrays may be located in ~nore
than one roof zone.
Using Table 1, determine the Roof Zone Setback Length, a (ft),
according to the width and height of the building on which
you are installing the pv system.

Step 5: Determine the Topographic Factor,
For the purposes of thi~ code compliance document, the
Topographic Factor, K~, is taken as equal to one (1), meaning,
the installation is on level ground (less than 10% slope). If the
installation is not on ]e~el ground, please consult ASCE 7-0S,
Section 6.5.7 and the lu¢al building authority to determine the
Topographic Factor.

Multiply the Net Design Wind Pressu re, pne~.~(~ (psf) (Step 4) by
the adjustment factor for height and exposure, A (Step 7),the
Topographic Factor, K~t (Step 5), and the hnportance Factor, I
(Step 8) using the following equation:

Part II. Procedure to Select Rail Span and Rail Type
[2.1.] Using Standard Beam Calculations, Structural Engineering Methodology
The procedure to determine the UniRac SolarMount series
rail type and rail span uses standard beam calculations and
structural engineering methodology. The beam calculations
are based on a simply supported beam conservatively, ignoring
the reductions allowed for supports of continuous beams over
multiple supports. Please refer to Part I for more information
on beam calculations, equations and assulllptlo~ls.
In using this document, obtaining correct results is
dependent upon the following:
1. Obtain the Snow Load for your area fiom your local building
official.
2. Obtain the Desit,m Wind Load,/)net. See
Part I (Procedure to Determine the Design Wind Load) for
more information on calculating the Design Wind Load.
3. Please Note: The terms rail span and footing spacing
are interchangeable in this document. See Figme 3 for
illustrations.
4. To use Table 8 and Table 9 the Dead Load fo~ your specific
installation must be less than 5 psf, including modules and
UniRac racking systems. If the Dead Load is g~ eater than 5
psf, see your UniRac distributor, a local structural engineer or
contact UniRac.
The following procedure will guide you in selecting a UniRac
rail for a flush mount installation. It will also help determine
the design loading imposed by the UniRac PV Mounting
Assembly that the building structure must be capable of
supporting.
Figure 3. Rail span and footing
spacing are interchangeable.
Step 1: Determine the Total Design Load
The Total Design Load, P (psf) is determined using ASCi: 7 05
2.4.1 (ASD Method equations 3,5,6 and 7) by addin<g t:e Snow
LoadI, S (psf), Desi~ Wind Load, p,~ (psf) from Part I, Step

Step 4: Select Rail Type
Selecting a span and rail type affects the price of your
installation. Longer spans produce fewer wall or roof
penetrations. However, longer spans create higher point load
forces on the building structure. A point load fvrce is the
amount of force transferred ro the building sn ucture at each
connection.
It is the installer's responsibility to veriff, that the building
structure is strong enoueh to suvvort the point load
forces.

[3.2.1] Planning your SolarMount® installations
The installation can be laid out with rails parallel to the rafters
or perpendicular to the rafters. Note that SolarMount rails
make excellent straight edges for doing layouts.
Center the installation area over the structural members as
much as possible.
Leave enough room to safely move around the array during
installation. Some building codes require minimum clearances
around such installations, and the user should be directed to
also check 'The Code'.
l'he width of the installation area equals tlr' '

[3.2.2] Laying out L-feet
L-feet (Fig. 7) are used for attachment through existing roof-
ing material, such as asphalt shingles, sheathing or sheet metal
to the building structure.
Use Figure 8 or 9 below to locate and mark the position of the
L-feet lag screw holes within the installation area.
If multiple rows are to be installed adjacent to one another, it
is not likely that each row will be centered above the rafters.
Adjust as needed, following the guidelines in Figure 9 as
closely as possible.

hole location.
Squirt sealant into the hole and on the shafts
of the lag screws. Seal the underside of the L
feet with a suitable sealant. Consult with the
company providing the roofing warranty.
Securely fasten the L-feet to the roof with
the lag screws. Ensure that the L-teet face as
shown in Figure 8 and 9. For greater ventila-
tion, the preferred method is ro place the
single-slotted square side of the L-foot against
the roof with the double-slotted sine perpen-
dicular to the roof. If the installer chooses to
mount the L-thor with the long leg against the
roof, the bolt slot closest to the bend must be
used.

Use Figure 11 or 12 to locate and mark the location of the
standoff lag screw holes within the installation area.
Remove the tile or shake underneath each standoff location,
exposing the roofing underlayment. Ensure that the standoff
base lies fiat on the underlayment, but remove no more mate-

[3.2.4] Installing SolarMount rails
Keep rail slots free of roofing grit or other debris. Foreign
matter will cause bolts to bind as they slide in the slots.
Installing Splices. If your installation uses SolarMount splice
bars, attach the rails together (Fig. 13) before mounting
the rails to the footings. Use splice bars only with flush
installations or those that use low-profile tilt legs.
If using more than one splice per rail, contact UniRac
concerning thermal expansion issues.
Mounting Rails on Footings. Rails may be attached to either
of two mounting holes in the L-feet (Fig. 14). Mount in the
lower hole for a low profile, more aesthetically pleasing
installation. Mount in the upper hole for a higher profile,
which will maximize airflow under the modules. This will cool
them more and may enhance performance in hotter climates.
Slide the V~-inch mounting bolts into the footing bolt slots.
Loosely attach the rails to the footings with the flange nuts.
Ensure that the rails are oriented to the footings as sbown in
Figure 8, 9, 11, or 12, whichever is appropriate.
Aligning the Rail Ends. Align one pair of rail ends to t he edge
of the installation area (Fig. 15 or Fig. 16).
The opposite pair of rail ends will overhang the side of the
installation area. Do not trim them oft' until the installation is
complete.
If the rails are perpendicular to the rafters (Fig. 15), either
end of the rails can be aligned, but the first module must be
installed at the aligned end.
If the rails are parallel to the rafters (Fig. 16), the aligned end
of the rails must face the lower edge of the roof. Securely
tighten all hardware after alignment is complete (28-32 ft lbs).
Mount modules to the rails as soon as possible. Large
temperature changes may bow the rails within a few hours if
module placement is delayed.

[3.2.5] Installing the modules
Pre-wiring Modules. If modules are the Plug and Play type,
no pre-wiring is required, and you can proceed directly to
"Installing the First Module" below.
If modules have standard J-boxes, each module should be
pre-wired with one end of the intermodule cable for ease of
installation. For safety reasons, module pre-wiring should not be
performed on the roof.
Leave covers off J-boxes. They will be installed when the
modules are installed on the rails.
Installing the First Module. In high-profile installations, the
safety bolt and flange nut must be fastened to the module bolt
slot at the aligned (lower) end of each rail. It will prevent the
lower end clamps and clamping bolts from sliding out of the tail
slot during installation.
If there is a return cable to the inverter, connect it to the first
module. Close the J-box cover. Secure the first module with
T-bolts and end clamps at the aligned end of each rail. Allow
half an inch between the rail ends and the end clamps (Fig.18)
Finger tighten flange nuts, center and align the module as
needed, and securely tighten the flange nuts (15 ft lbs).
Installing the Other Modules. Lay the second module face
down (glass to glass) on the first module. Connect intermodule
cable to the second mod u [e and close the J-box cover. Turn thc
second module face up (Fig. 17). With T-bolts, mid-damps and
flange nuts, secure the adjacent sides of the first and second
modules. Align the second module and securely tighten the
flange nuts (Fig. 19),
For a neat installation, fasten wire management devices to rails
with self-drilfing screws.
Repeat the procedure until al/modules are installed. Attach the
outside edge of the last module to the rail with end clamps.
Trim off any excess rail, being careful not to cut into the roof
Allow half an inch between the end clmnp and the end of the lail

[3.3.1] Planning the installation area
Decide on an arrangement for clips, rails, and L-feet (Fig. 22)
Use Arrangement A if the full width of the rails contacts the
module. Otherwise use Arrangement B.
Caution: If you choose Arrangement B, either
(1) use the upper mounting holes of the L-feet or
(2) be certain that the L-feel and clip positions don't
conflict.
If rails must be parallel ro the rafters, it is unlikely that they
can be spaced to march rafters. In that case, add structural
supports - either sleepers ow, r the roof or monnting blocks
beneath it. These additional members must meet code; if in
doubt, consult a professional engineer.
Never secure the footings to the roof decking alone. Such an
arrangement will not meet code and leaves the installation
and the roof itself vulnerable to severe damage from wind.
Leave enough room to safely move around the array during
installation. The width of a rail-module assembly equals the
length of one module. Note that L-feet may extend beyond
the width of the assembly by as tnuch as 2 inches on each
side. The length of the assembly equals the total width of the
modules.

[3.3.2] Laying out the installing L-feet
L-feet are used for installation through
existing low profile roofing material, such
as asphalt shingles or sheet metal. They
are also used for most ground mount
installations. 'Fo ensure that the L-feet will
be easily accessible during flush installation:
· Use the PV module mounting holes
nearest the ends of the modules.
· Situate the rails so that footing bolt
slots face outward.
The single slotted square side of the L-foot
must always lie against the roof with the
double-slotted side pelpendicular to the
roof.
Foot spacing (along the same rail) and rail
overhang depend on design wind loads.
Install half the L-feet:
· If rails are perpendicular to rafters
(Fig. 23), install the feet closest to
the lower edge of the roof.
· If rails are parallel to rafters (Fig
24), install the feet for one of the
rails, but not both.
For the L-feet being installed now, drill pilot
holes through the tooling into the center of
the rafter at each lag sciew fiole location.
Squirt sealant into tl~e hole and onto the
shafts of the lag sc~ c~ss. Seal the underside
of the L-feet with a sealant. Securely fasten
the L-feet to the building structure with the
]ag screws. Ensure that the L-feet face as
shown in Figure 23 or Figure 24.
Hold the rest of ~he l. f~et and fasteners

[3.3.3] Attaching modules to the rails
Lay the modules for a given panel face down on a surface
that will not damage the rnodule glass. Align the edges of the
modules and snug them together (Fig. 21, page22).
Trim the rails to the total width of the modules to be mounted.
Place a rail adjacent to the outer mounting holes. Orient
the footing bolt slot outward. Place a clip slot adjacent to
the mounting holes, following tbe arrangement you selected
earlier.
Assemble the clips, mounting bolts, and flange nuts. 'Ibrque
the flange nuts to 1S-foot-pounds.
Wire the modules as needed, l'or safety reasons, module
wiring should not be ped'ormed on a roof. For a neat
installation, fasten cable clamps to rails with self-tapping
screws.
[3.3.4] Installing the module-rail assembly
Bring the module-rail assembly to the installation site. Keep
rail slots free of debris that might cause bolts to bind in the
slots.
Consider the weight of a fully assembled panel. UniRac rec-
ommends safety lines whenever lifting one to a roof.
Align the panel with the p~eviously installed L-feet. Slide 3/8
inch L-foot mounting bolts onto the rail and align them with
the L-feet mounting holes .\ttach the panel to the L-feet and
finger tighten the flange m~s.
Rails may be attached to either of two mounting holes in the
footings (Fig. 25).
· Mount in the lower hole for a low, more aethetically
pleasing installation.
· Or mount in the upper hole to maximize a cooling
airflow under the modtdt!s. This may enhance perfor-
mance in hotter clirnate~
Adjust the position of the panel as needed to fit the installa
tion area. Slide the remaining/-feet bolts onto the other rail,
attach L-feet, and finger tighten with flange nuts. Align L-feet
with mounting holes previously drilled into the roof. Install
lag bolts into remaining L feet as described in "La3dng out ami
installing L-feet" above.
Torque all footing flange nu~s to 30 pounds. Verify that all lag
bolts are securely fastened.
