Qj 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. 2 SolarMount Unirac Code-Compliant Installation Manual :9° U N IRAC 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 questions about the definitions orprocedurrs presented in this manual. Unirac uses Method 1, the Simplified Method, for calculating the Design Wind Load for Pner (psf) - AKzd pner3o pressures on components and cladding in this document. pncr (psj) = Design Wind Load The method described in this document is valid for flush, no tilt, SolarMount Series applications on either roofs or walls. A = adjustmentfactor 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 &t = Topographic Factor at mean roof height, h (ft) more than 10" space between the roof surface, and the bottom of the FV panels. I = Importance Factor This method is not approved for open structure calculations. pner3o (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.

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 7bta1 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 are based on a simply supported beam conservatively, ignoring 2.4.1 (ASD Method equations 3,5,6 and 7) by adding the Snow the reductions allowed for supports of continuous beams over Loadl, S (psf), Design Wind Load, peat (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.

See Figure 3 for illustrations. P (psf) = 0.6D + 1.0p,,, (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 racldng systems. If the Dead Load is greater than 5 S =Snow Load (psf) psf, see your Unirac distributor, a local structural engineer or contact Unirac. The following procedure will guide you in selecting a Unirac p" t = Design Wind Load (psf) (Positive for downforce, negative for uplift) rail for a flush mount installation. It will also help determine the design loading imposed by the Unirac PV Mounting The maximum Dead Load, D (psf), is 5 psf based on market Assembly that the building structure must be capable of research and internal data supporting. t Snow Load Reduction - The snow load can be reduced according to Chapter 7 ofASCE 7-05. The reduction is a function of the roof slope, Exposure Factor, Importance Factor and Thermal Factor. Please refer to Chapter7 ofASCE 7-05 for more information. Figure 3.

Foreign matter will cause bolts to bind as they slide in the slots. i Installing Splices. If your installation uses SolarMount splice bars, attach y the rails together (Fig. 13) before mounting the rails to the footings. Use 7 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 908.1, Splices/Expansion Joints.) Figure 13. Splice bars slide into the footing host if using more than one splice per rail, contact Unirac concerning slots of Solarmfomt rail sections. 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 Clamping for a higher profile, which will maximize airflow under the modules. This bolt slot will cool them more and may enhance performance in hotter climates.

Foot-to-rail splice attachment 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 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.
