L Installer's Responsibilities
Please review this manual thoroughly before installing your SolarMount is much more than a product.
SolarMount system. It's a system of engineered components that can be assembled
This manual provides(1)supporting documentation for into a wide variety of PV mounting structures.With
building permit applications relating to UniRac's SolarMount SolarMount you'll be able to solve virtually any PV module
Universal PV Module Mounting system,and(2)planning and mounting challenge.
assembly instructions for SolarMount It's also a system of technical support:complete installation
SolarMount products,when installed in accordance with and code compliance documentation,an on-line SolarMount
this bulletin,will be structurally adequate and will meet the Estimator,person-to-person customer service,and design
structural requirements of the IBC 2006,IBC 2003,ASCE 7- assistance to help you solve the toughest challenges.
02,ASCE 7-05 and California Building Code 2007(collectively Which is why SolarMount is PV's most widely used mounting
referred to as"the Code").UniRac also provides a limited system.
warranty on SolarMount products(page 26).
OThe 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.

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 for more clarification on the use of Method I.Lower design
by the American Society of Civil Engineers and referenced in wind loads may be obtained by applying Method II from ASCE
the International Building Code 2006. For purposes of this 7-05.Consult with a licensed engineer if you want to use
document,the values,equations and procedures used in this Method II procedures.
document reference ASCE 7-05,Minimum Design Loads for The equation for determining the Design Wind Load for
Buildings and Other Structures. Please refer to ASCE 7-05 if components and cladding is:
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 pner(Psi)=i1KZcI pner3o
pressures on components and cladding in this document.
Net(psf)=Design Wind Load
The method described in this document is valid for flush,no
tilt,SolarMount Series applications on either roofs or walls. rl=adjustment factor for height and exposure category
Flush is defined as panels parallel to the surface(or with no
more than 3"difference between ends of assembly)with no Kzt=Topographic Factor at mean roof height,h(ft)
more than 10"space between the roof surface,and the bottom
I=Importance Factor
of the PV panels.
This method is not approved for open structure calculations. pnet3o(psf)=net design wind pressure for Exposure B,at height
Applications of these procedures is subject to the following =30,I=1
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 You will also need to know the following information:
on structures greater than 60 feet,contact your local UniRac
Distributor. Basic Wind Speed=V(mph),the largest 3 second gust of wind in
2.The building must be enclosed,not an open or partially the last 50 years.
enclosed structure,for example a carport. h(ft)=total roof height for flat roof buildings or mean roof
3.The building is regular shaped with no unusual geometrical height for pitched roof buildings
irregularity in spatial form,for example a geodesic dome. Effective Wind Area(sf)=minimum total continuous area of
4.The building is not in an extreme geographic location such modules being installed
as a narrow canyon or steep cliff.
5.The building has a flat or gable roof with a pitch less than 45 Roof Zone=the area of the roof you are installing the pv system
degrees or a hip roof with a pitch less than 27 degrees. according to Figure 2,page 5.
6.If your installation does not conform to these requirements Roof Zone Setback Length=a(ft)
please contact your local UniRac distributor,a local
professional engineer or UniRac Roof Pitch(degrees)
If your installation is outside the United States or does not Exposure Category
meet all of these limitations,consult a local professional
engineer or your local building authority.Consult ASCE 7-05

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,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.

Part H. 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 Step 1:Determine the Total Design Load
rail type and rail span uses standard beam calculations and The Total Design Load,P(psf)is determined using ASCE 7-05
structural engineering methodology. The beam calculations 2.4.1(ASD Method equations 3,5,6 and 7)by adding the Snow
are based on a simply supported beam conservatively,ignoring
the reductions allowed for supports of continuous beams over Loadl,S(psf),Design Wind Load,Net(psf)from Part I,Step
multiple supports.Please refer to Part I for more information 9 and the Dead Load(psf).Both Uplift and Downforce Wind
on beam calculations,equations and assumptions. Loads calculated in Step 9 of Part 2 must be investigated. Use
Table 7 to calculate the Total Design Load for the load cases.
In using this document,obtaining correct results is Use the maximum absolute value of the three downforce cases
dependent upon the following: and the uplift case for sizing the rail.Use the uplift case only

2.Obtain the Design Wind Load,p,tet. See P(psf)=1.OD+I.OSI(downforce case 1)
Part I(Procedure to Determine the Design Wind Load)for
more information on calculating the Design Wind Load. P(psf)=1.OD+I.Opnet(downforce case 2)
3.Please Note:The terms rail span and footing spacing p(psf)=1.OD+0.7551+0.75pnet(downforce case 3)
are interchangeable in this document. See Figure 3 for
illustrations. P(psf)=0.6D-I-OPnet (uplift)
4.To use Table 8 and Table 9 the Dead Load for your specific
installation must be less than 5 psf,including modules and D=Dead Load(psf)
UniRac racking systems. If the Dead Load is greater than 5
psf,see your UniRac distributor,a local structural engineer or S=Snow Load(psf)
contact Unillac.
The following procedure will guide you in selecting a UniRac pner=Design Wind Load(psf)
rail for a flush mount installation.It will also help determine The maximum Dead Load,D(psf),is 5 psf based on market
the design loading imposed by the UniRac PV Mounting research and internal data.
Assembly that the building structure must be capable of 1 Snow Load Reduction-The snow load can be reduced according
supporting. to Chapter 7 of ASCE 7-05. The reduction is a function of the roof

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
