These building codes require that wind loading be determined based upon ASCE 7-05 and Unirac's Manual 227 utilizes ASCE 7-05 that matches Method 1 for which Unirac Table 2 is based upon, that which.is dependent upon conditions of spatial form,height and other structure parameters that are specified in the code provisions for determining the applied wind loading pressures imposed onto the Unirac SolarMountTM rails supporting solar panels. The SolarMountTM railing and anchorage requirements for the installation are properly represented in the Installation Manual 227. For other conditions,the determination of wind pressures should be determined by the aforementioned New York State Building Code and ASCE 7 procedures. James A.Marx,Jr. PE Page 2 of 2 The design verification is based on: I. ASCE7-02/05—ASCE Standard 11. "Steel Construction Manual," 13th Ed., American Institute of Steel Construction, Chicago, IL,2005. III. "Aluminum Design Manual",The Aluminum Association, Washington D.C., 2005. IV. Mechanical Properties and Static Load Testing of Unirac extruded rails and related components obtained from Dr. Walter Gerstle, PE,Department of Civil Engineering, University of New Mexico,Albuquerque,NM Use: Unirac SolarMountTM is evaluated for use in locations where wind pressure requirements do not exceed 50 psf or snow load conditions do not exceed 45 psf around snow loads. For loading in excess of either of the above stated conditions,Unirac, Inc. should be contacted for suitability of installation. By this letter,I certify that the Unirac SolarMountTM assembly, when installed in accordance with the Installation Manual 227 will meet the requirements of the building codes adopted by New York State. Others should evaluate the structure to which the Unirac SolarMountTm system is to be connected on a case-by-case basis,per Part I— Installer's Responsibilities of the Installation Manual, to ensure its adequacy to accept attachments and to support all applied loadings per the building code.

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 2009. 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 pnet(psf)= lKztl pnet3o pressures on components and cladding in this document. pnet(P.f)s =Design Wind Load The method described in this document is valid for flush,no tilt,SolarMount Series applications on either roofs or walls. A=adjustment factor for building 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 feet,I=1.0 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 heightforflat roof buildings or mean roof height 3.The building is regular shaped with no unusual geometrical for pitched roof buildings irregularity in spatial form,for example a geodesic dome. Roof Pitch(degrees) 4.The building is not in an extreme geographic location such as a narrow canyon or steep cliff. This manual will help you determine: 5.The building has a flat or gable roof with a pitch less than 45 Effective Wind Area(sf)=minimum total continuous area of degrees or a hip roof with a pitch less than 27 degrees. modules being installed(Step 2) 6.If your installation does not conform to these requirements please contact your local Unirac distributor or a local Roof Zone=the area of the roof you'are installing the pv system professional engineer. according to Step 3. If your installation is outside the United States or does not Roof Zone Dimension=a(ft)(Step 3) meet all of these limitations,consult a local professional engineer or your local building authority.Consult ASCE 7-05 Exposure Category(Step 6) [1.2.] Procedure to Calculate Total Design Wind The procedure for determining the Design Wind Load can be Step 2:Determining Effective Wind Area broken into steps that include looking up several values in Determine the smallest area of continuous modules you will different tables.Table 5 has been provided as a worksheet for be installing.

Page 18 SolarMount Unirac Code-Compliant Installation Manual 10'U N I RAC [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 'k, 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. Although structural,the joint is not as strong as the rail itself.A rail should always be supported by more than one footing on both sides of the splice. (Reference installation manual 908,Splices/Expansion Joints.) Figure 13.Splice bars slide into the footing bolt slots of SolarMount rail sections. 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. Clamping Slide the%-inch mounting bolts into the footing bolt slots. Loosely attach bolt lot the rails to the footings with the flange nuts. i air Ensure that the rails are oriented to the footings as shown in Figure 8,9, Mounting 11,or 12,whichever is appropriate. slots Footing \ �r Aligning the Rail End:Align one pair of rail ends to the edge of the bolt slot ��\ 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 off until the installation is complete. If the rails are perpendicular to the rafters(Fig.15),either end of the rails Figure 14.Foot-to-rail splice attachment 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(20 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. Edge of installation area —sl �3 i I �.

It will prevent the Module frame lower end damps and clamping bolts from sliding out of the rail 1/2"minimum slot during installation.
