I have reviewed the solar energy system installation at the subject address. The units have been installed in
accordance with the manufacturer's installation instructions and the approved construction drawing. I have
determined that the installation meets the requirements of the 2007 NYS Building Code, and ASCE7-05,
specific to the fastening of panels to the roof, to comply with the NYS code re: 120 mph winds.
To my best belief and knowledge, the work in this document is accurate, conforms with the governing codes

i. Installer's Responsibilities
Please review this manua! thoroughly before installing your
SunFrame system.
This manual provides (1) supporting documentation for
building permit applications relating to Unirac's SunFrame
Universal PV Module Mounting system, and (2) planning and
assembly instructions for SunFrame
SunFrame products, when installed in accordance with this
bulletin, will be structurally adequate and will meet the
structural requirements oftbe IBG 2006, IBC 2003, ASCE 7-
02, ASCE 7-05 and Galifornia Building Code 2007 (collectively
referred to as "the Gode'). Unirac also provides a limited
warranty on SunFrame products (page 30).
SunFrame offers finish choices and low, clean lines that
become as natural a part of a home as a skylight. It delivers the
installation ease you've come to expect from Unirac.
Whether for pitched roofs and parking roof structures,
SunFrame was designed from the outset to promote superior
aesthetics. Modules are flush mounted in low, gap-flee rows,
and visible components match clear or dark modufe flames.
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
stxuctural 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 pares 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.

Part I. Procedure to Determine the Design Wind Load
[1.1.] Using the Simplified Method - ASGE 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 ASGE 7-05, Minimum Design Loads for
Buildings and Other Structures, Please refer to ASC£ 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 descnZed in this document is valid for flush, no
tik, SunFrame 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 for open structure calculations.
Applications of these procedures is subject to the folfowing
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 bo 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 mom clarification on the use of Method I. Lower design
wind loads may bo obtained by applying Method II from ASCE
7-05. Consult with a licensed engineer if you want to use
Method 1I procedures.
The equation for determining the Design Wind Load for
components and cladding is:
p,et (psf) = AKzd p,~t~o
pnet (ps]') = Design Wind Load
= adjustment factor for height and exposure category
= Topographic Factor at mean roof height, h (ft)
Importance Factor
pn~tso (psi9 = net design wind pressure for Expnsure B, at height
=30, I=1
You will also need to know the following information:
Basic Wind Speed = V (mph), the largest 3 second ~t of wind in
the last5Oyears.
h (ft) = total roofheightforflat roof buildings or mean roof
height for pitched roof bufidings
Effective Wind grea (sf) = minimum total continuous area of
modules being installed
Roof Zone = the area of the roof yan are installing the pv system
according to Figure 2, page 5.
Roof Zone Setback Length = a (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 (mph) by consulting your
local building department or locating your installation on the
maps in Figure 1, page 4.
Step 2: Deterrotnlng Effective Wind Area
Determine the smallest area of continuous modules you will
be installing. This is the smallest area tributary (contributing
load) to a support or to a simple-span of rail. That area is the
Effective Wind Area.

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

Step 3: Determine Roof Zone (continued)
Using Roof Zone Setback Length, a, determine the roof zone
locations according to your roof type, gable, hip or monoslope.
Determine in which roof zone your pv system is located, Zone
1, 2, or 3 according to Figure 2.

Step 4: Determine Net Design Wind Pressure, pnetao
Using the Effective Wind Area (Step 2), Roof Zone Location
(Step 3), and Basic Wind Speed (Step 1), look up the
appropriate Net Design Wind Pressure in Table 2, page 6. Use
the Effective WindArea value in the table which is smaller than
the value calculated in Step 2. If the installation is located on a
roof overhang, use Table 3, page Z
Both downforce and uplift pressures must be considered
in overall design. Refer to Section II, Step 1 for applying
down force and uplift pressures. Positive values are acting
toward the surface. Negative values are acting away from the
surface.

Topographic Factor, K~e, is taken as equal to one (1), meaning,
the installation is on level ground (less than 10% slope). If the
installation is not on level ground, please consult ASCE 7-05,
Section 6.5.7 and the local building authority to determine the
Topographic Factor.
Step 6: Determine Exposure Category (B, C, D)
Determine the Exposure Category by using the following
definitions for Exposure Categories.
TheASCF./SE/7-05* defines wind exposure categories as
follows:
~xvoso~ a is urban and suburban areas, wooded
areas, or other terrain with numerous closely spaced
obstructions having the size of single family dwellings.
EXPOSUR~ c has open terrain with scattered obstruc-
tions having heights generally less than 30 feet. This
category includes flat open country, grasslands, and all
water surfaces in hurricane prone regions.
I~POSUR~ O has flat, unobstructed areas and water
surfaces outside hurrican prone regions. This category
includes smooth mud flats, salt fiats, and unbroken ice.
Also see ASCE 7-05 pages 287-291 for further explanation and
explanatory photographs, and confirm your selection with the
local building authority.

Multiply the Net Design Wind Pressure, pnet~o (pst') (Step 4) by
the adjustment factor for height and exposure, A (Step 7),the
Topographic Factor, K~t (Step 5), and the Importance Factor, I
(Step 8) using the following equation:
pn*t Cpsf) = AK~d p.e~o
pnet (psf) = Design Wind Load (l O psf minimum)

Use TaNe S below to calculate Design Wind Load.
The Design Wind Load will be used in Part I1 to select the

Part II. Procedure to Select Rail Span and Rail Type
[2.1.] Using Standard Beam Galculations, Structural Engineering Methodology
The procedure to determine the Unirac SunFrame 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 assumptions.
In using this document, obtaining correct results is
dependent upon the following:
1. Obtain the Snow Load for your area from your local building
official.
2. Obtain the Design Wind Load, pnet. 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 Figure 3 for
illustrations.
4. To use Table 8 and Table 9 the Dead Load for your specific
installation must be less than 5 psf, including modules and
Unkac racking systems. If the Dead Load is greater 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.
Step 1: Determine the Total Design Load
The TotalDesign Load, P (psf) is determined using ASCE 7-05
2.4.1 (ASD Method equations 3,5,6 and 7) by adding the Snow
Load1, S (pst), Design Wind Load, pnet (psf) from Part 1, Step
9 and the Dead Load (ps]). Both Uplift and Downforce Wind
Loads calculated in Step 9 of Part 2 must be investigated. Use
Table 7 to calculate the Total Design Load for the toad cases.
Use the maximum absolute value of the three downforce cases
and the uplift case for sizing the rail. Use the uplift case only
for sizing lag bolts pull out capacities (Part II, Step 6).
P [psf) = 1.OD + 1.0S1 (downforce case 1)
P (psf) = 1.OD + 1.0pnet (downforce case 2)
P (psf) = 1.OD + 0.75Sl + 0.75pnet (downforce case 3)
P (pSf) = 0.6D - 1.0pnet (uplift)
O = DeadLoad (psf)
S = SnowLoad (ps.O
pnet = Design Wind Load (psfJ
The maximum Dead Load, D (psf), is 5 psfbased on market
research and internal data.
1 Snow Load Reduction - The snow load can be reduced according
to Chapter 7 of ASCE 7-05. The reduction ts a function of the roof
slope, Exposure Factor, Importance Factor and Thermal Factor.
Please refer to Chapter 7 of ASCE 7-05for more information.
Figure 3. Rail span and footing
spacing are interchangeable.
Note: Modules must be centered symraetrically on
the rails (+/- 2 *), us shown in Figure 3. If this is
not the case, call Unirac for assistance.

Step 2: Determine the Distributed Load on the ~il,
w (?~)
Determine the Distributed Load, w Cpi. f), by multiplying the
module width, B eft), by the Total Design Load, P (psf). Use the
maximum absolute value of the three downforce cases and the
Uplift Case. We assume each module is supported by one rail.
w=PB
w = Distributed Load (pounds per linear foot, plf)
B = Module Length Perpendicular to Rails (ft)
P = TotalDesign Pressure (pounds per square foot, psf)
Step 3: Determine Rail Span/L-Foot Spacing
Using the distributed load, w, from Part II, Step 2, look up the
allowable spans, L, for SunFrame.
There are two tables, L-Foot SunFrame Series Rail Span Table
and Double L-Foot SunFrame Series Rail Span Table. The
L-Foot SunFrame Series Rail Span Table uses a single L-foot
connection to the roof, wall or stand-off. The point load
connection from the rail to the L-foot can be increased by
using a double L-foot in the installation. Please refer to Part
III for more installation information.

Table 9. Double L-Foot SunFrame Series Rail Span
Step 4: Select Rail Type
Selecting a span 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 force is the amount of force
transferred to the building structure at each connection.
It is the installer's resvonsibilitv to verify that the buildine
structure is stron~t enomth to suo~ort the ~oint load
forces.
Step S: Determine the Downforee Point Load, R (/bs),
at each connection based on rail span
When designing the Unirac Flush Mount Installation, you
must consider the downforce Point Load, R (lbs) on the roof
The Downforce, Point Load, R (~bs), is determined by
multiplying the Total Design Load, P (psf) (Step 1) by the Pa//
Span, L (ft.) (Step 3) and the Module Length Perpendicular to
the Rails, B ~ft).
R (lbs) = ?LB
R = PointLoad ~bs)
P = TotalDesign Load (psf)
L = Pail Span (ft)
B = Module Length Perpendicular to Rails (ft)
It is the installer's responsibility to verify that the building
structure is strong enough to support the maximum point
loads calculated according to Step 5.

Installing the array
Safe, efficient SunFrame installation involves three principal tasks:
A. Laying out t be installation area and planning for material conservatinn.
B. lnstallingfootingsandrails, beginningwithtbelowestrowandmovinguptheroof.
C. Placing modules and cap strips, beginning with the highest row and moving down the roof.
The following illustrated steps describe the procedure in detail. Before beginning, please note
these important considerations.
Footings must be lagged into structural members. Never attach them to the deck/ng
Aalone, lvhich leaves both the array and roof susceptible to severe damage.
For array widths or lengths greater than 32feet, contact Unirac concerning thermal
expanswn lssues.
Sample layout, illustrated in Figure 4
Assumptions: 12 modules (60' x 36 '),
arranged in 3 rows of 4 modules
Array width = 144 ' [36' module width x 4 modules per row)
Array length = 180' (60' module length x 3 rows)
+ 3' (1vz ' end rail width x 2 rails)
+ ll,5' (3'4 ' between-module rail width x 2 rails)
1. Laying out the installation area
Always install gunFrame rails perpendicalar to rafters. (These
instructions assume typical rafters that run from the gutter
to the peak of the roof. If this is not the case, contact Unirac.)
Rails are typically mounted horizontally (parallel to the lower
edge of the roof), and mast be mounted within 10 degrees of
horizontal.
Leave adequate room to move safely around the array during
installation. During module installation, you will need to slide
one module in each row about a foot beyond the end of the
rails on one side. Using the number of rows and the number
of modules per row in your instai]ation, determine the size of
your array area following Figure 6.

2. Installing the lowest row of L-feet and rail
In the lowest row, it is not necessary to use L-foot adjusting
sliders, even if you plan to use them in subsequent rows. Install
L-feet directly onto low profile roofing material such as asphalt
shingles or sheet metal. (For high profile roofs, such as tile
or shake, use optional standoffs with flashing to raise L-feet.
L-feet must be flush with or above the highest point of the roof
surface.)
L-feet can be placed with the double-slotted side against the
roof surface ~as in Fig. 7) or with the single-slotted side against
the roof [which increases air drculation beneath modules).
Module-to-roof dimensions are listed on page 15 for both ar-
rangements.
AIf you are using L-foot adjusting sliders, you must use
the short side of the the L-foot against the roof in the
first row. See Figure 9 below.
If you are using both L-foot adjusting sliders and standoffs,
see the upper box on page 11.
Install the first mw of L-feet at the lower edge of the instal-
lation area (Fig. 8~ Ensure feet are aligned by using a chalk
line. (A SunFrame rail can also be used as a straight edge.)
Position the L-feet with respect to the lower edge of the roof as
illustrated in Figures 7 and 8.
Drill a pilot hole through roof into the center of the rafter at
each L-foot lag screw hole location. Apply weatherproof sealant into the hole and onto shafts of the
lag screws. Seal the underside of the L-feet with a suitable weatherproof sealant.
Fasten the L-feet to the roof with the lag screws. If the double slotted sides of the L-feet are against
the roof, lag through the slot nearest the bend in the L-foot (Figs. 7 and 8).

between the ends of the modules and either raft. Uf pan-head
screw heads represent the true end of the modules, be sure
the screw heads touch the rails on both ends.) Tighten the lag
screw on that end. glide the module down the rails, snugging
the rails and tightening the remaining ]ag screws as you go.

Preplanning material use for your particular array can prevent
structural or aesthetic problems, particularly those caused by
ver3~ short lengths of rail or cap strip. This example illustrates

every 8 inches, beginning 4 inches from the ends of
the rails).
· One screw 4 inches or less from the each end
of every rail segment. Wherever there is no
prepunched hole within 4 inches of an end of a
segment, drill a 1/4-inch hole 2 inches from the end
of the segment and install a cap strip sccew. 0n
most cases, you can avoid this situation with good
material planning.)
Structural requirements always take precedence, but usually
good planning can also achieve both material conservation
and superior aesthetics. This example conserves material
and achieves two specific aesthetic goals:
· Cap strip screws must align across the mils.
· End screws must be equidistant from both sides of
the array.
The example assumes an array of three rows, each holding
five modules 41 inches wide. Thus, four 205-inch mil
rails and cap strips
assemblies and cap strip assemblies need to be cut and
spliced from 192-inch sections of rail and cap strip. The
example illustrates one means of doing so, without violating
structural requirements or aesthetic goals.
Rail segments come from five 192-inch lengths, lettered A
thru E. Rail A, for example, is cut into two 96-inch segments,
with one segment spliced into each of the first two mils.
Similarly, five 192-inch cap strips are designated V through
Z.
All cap strip segments are cut ar the midpoint between
prepunched screw holes. For each rail, start with the cap
strip segment that crosses the array center line, and position
over the center line so that the appropriate holes are spaced
equally on either side.
Position each cap strip onto its rail and mark its trim point.
Remove and trim before final mounting.
Preliminary footing and splice positions must be
checked against structural requirements in "Footing
and splicing requirements" (p.11). In this example,
the center of the array is offset 2 inches from the center
~lfter. This prevents ralI splices BD (3rd rail) and CE
(4th rail)from falling too close to the center of the spans
between footiags (Requirement 3, p. 11). Because foot-
i~ are notvlsible from ground level, there is negligible
aesthetic loss.

6. Securing the first module
Gather sufficient lengths of cap strip
to cover the length of the first rail. For
maximum visual appeal and material
conservation see "Material planning for
mils and cap strips" (p. 13).
Slide the first module into final position
at one end of the array. Lay the remaining
modules in the top row, leaving a gap
about a Eot wide between the first and
second modules (Fig. 13).
The temporary gap allows the installer to
place one of his leet between modules. He
can access the section of the cap strip he
needs to secure while leaning toward the
peak of the roof. For the time being, the
last module may overhang the rail by up
to one third its width.
Attach the end o£tbe cap strip with
the cap strip screws (Fig. 13, inset), so
that the upper end of the first module is
Figure 13. Begin cap strip installation.
AT he structural integrity of your array requires that cap
strip screws fully engage the threaded rail. Use the cap
strip screws supplied with your cap strips. Any substitute
screws must be ~-20 ~/pe F thread cutting (18-8 stainless
steel) and the correct length. See Table 4 (pg. 15) to match
screw length w the si~e cap strip in your installation.
AEvery cap strip segment must have a cap strip screw 4
inches or less from each end. If the nearest predrilled
hole fulls more than 4 inshes from any end, drill a
~-insh hole 2 inches from the end and install an additional
AWherever necessary to a new cap strip
it
hole,
drill a V~-inch hole before installing the cap strip screw.
7. Installing the remaining modules in the top row
Slide the next module into final position and install the screws
to secure it (Fig. 14). For a neat installation, use cable ties to
attach excess wiring to the rail beneath the flanges, Unirads
cable ties can be attached to the SunFrame rail by drilling a
V,-inch hole in the rail and pushing the end of the tie into the
hole.
Gontinue the process until all modules in the top row are in
final place and secured from the top. When complete, every
prepunched hole in the cap strip will be secured by a screw,
and the top end of the first row of modules will be secure.
8. Installing the remaining modules row by row
Repeat Steps 6 and 7 for the remaining rows (Fig. 15). Each
subsequent cap strip will secure the tops to the modules being
installed and the bottoms of the modules in the row above.
Place the final cap strip in the lowest rail, securing the bottom
of the lowest module row.

always allowing access m the section of cap strip being secured.

Attach the end caps to the ends of the rails by securing with
the truss head sheet metal screws provided (Fig. 16).

Frequently asked questions about standoffs and roof variations
How high above the roof is a SunFrame array?.
The answer depends on the orientation of your L-feet and
the length of your standoffs, if used. See the illustration ap-
propriate to your installation.
How can I seal the roof penetration required when
standoffs are lagged below the roofing material?
Many types and brands o f flashing can be used with Sun-
Frame. Unirac offers an Oatey® "No-Calk" flashings for
its steel standoffs and Oatey® or Unirac flashings for its
aluminum two-pieee standoffs. See our SunFrame Pro-Pak
Price List.
How do I attach gunFrame to a standing-seam metal
roof?.
A good solution comes from Metal Roof Innovations, Ltd.
(MRI). They manufacture the S-5! ~ clamp, designed to at-
tach a wide variety of products to most standing-seam metal
roofs. It is an elegant solution that eliminates flashings and
penetrations altogether.
