Please write to publications@unirac.com. :FUNIRAC Unirac Code-Compliant InstaUation Manual SolarMount 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 Unirads 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 2009, ASCE 7-05 and California Building Code 2010 (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 module mounting challenge. It's also a system of technical support: complete installation and code compliance documentation, an on-line SolarMount Estimator, person-to-person customer service, and design assistance to help you solve the toughest challenges. This is why SolarMount is PVs most widely used mounting systern. The installer is solelv 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 mayvoid 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; • 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. 0 SolarMount Unirac Code-Compliant Installation Manual :FUNIRAC 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 2009. 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 (f you have anyquestions about thedejinitions orprocedures 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 for open structure calculations. Applications oftheseprocedures is subject to thefollowing 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 or a local professional engineer. 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. Lower design wind loads may be obtained by applying Method II from ASCE 7-05. Consult with a licensed engineer if you want to use Method II procedures. The equation for determining the Design Wind Load for components and cladling is: pnet (psD = AKId pnetio pnet (psD = Design Wind Load X = adjustmentfactorfor building height and exposure category Kzt = Topographic Factor at mean roof height h (ft) I = Importance Factor pnedo (psf) = net design wind pressure for Exposure B, at height = 30.feet I = 1.0 You will also need to know the following information: Basic Wind Speed = V (mph), the largest 3 second gust of wind in the last 50 years. h (ft) = total roof heightforflat roof buildings or mean roof height for pitched roof buildings Roof Pitch (degrees) This manual will help you determine: Effective Wind Area (sf) = minimum total continuous area of modules being installed (Step 2) Roof Zone = the area of the roof you are installing the pv system according to Step 3. Roof Zone Dimension = a Ut) (Step 3) Exposure Category (Step 6) [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. Table 5 has been provided as a worksheet for the following 9 steps (page 8) 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: Determining Eective WindArea 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, the total area of the fewest number of modules on a run of rails. If the smallest area of continuous modules exceeds 100 sq ft, use 100 sq ft (See Table 2). If less, round down to values available in Table 2. :1'UNIRAC Unirac Code-Compliant Installation Manual SolarMount 613---IIFLIIKE *7 41*'4 21*Yaitav, ,9'.24:645 /3/01111*8IEANAIE:ipw:Jivilip:9:73:%:*44*%1·4.-MN222:722:WE.•.N,•..40::: ::=:·€:Na..y*;0#WARf¢42#&*991!ip:41:1**63fi;400%*:trjE-'4*tek --®4•!Ef",Ii*t%,L.A,I,I;ii&);BA:.b,¥8Vg*f' - - .- -I . r :' 1 1 ill:::lic::iill)fla#Mit&11£14&/1/4/*SElf#ile#irl,44?/tifisildlil .,1 .94& ,=714 ' . ill- .......:, , ..,1,41'4/914, 1 , . #':0 .4210 9..Ir 100(45) /1130(58) 110(49) 120(54) Step 3: Determine Roof/Wall Zone The Design Wind Load will vary based on where the installation is located on a roof.

Step 5: Determine the Topographic Factor, Ket For the purposes of this code compliance document, the Topographic Factor, Kzt, is taken as equal to one (1), meaning, the installation is surrounded by level ground (less than 10% slope). If the installation is not surrounded by 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 Surface Roughness Categories. SURFACE ROUGHNESS C: has open terrain with seat- tered obstructions having heights generally less than 30 feet. This category includes fiat open country, grasslands, and all water surfaces in hurricane prone regions. SURFACE ROUGHNESS D: has flat, unobstructed areas and water surfaces outside hurricane prone regions. This category includes smooth mud fiats, salt flats, and unbroken ice. The ASCE/SEI 7-05 defines wind surface roughness categories as follows: SURFACE ROUGHNESS B: is urban and suburban areas, wooded areas, or other terrain with numerous closely spaced obstructions having the size of single family dwellings. Also see ASCE 7-05 pages 287-291 for further explanation and explanatory photographs, and confirm your selection with the local building authority. :1:UNIRAC Unirac Code-Compliant Installation Manual SolarMount Step 7: Determine adjustmentfactorfor height and exposure category, A Using the Exposure Category (Step 6) and the roofheight h 04 look up the adjustmentjactorfbr height and exposure in Table 4.

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 assumptions. If beams are installed perpendicular to the eaves on a roof steeper than a 4/12 pitch in an area with a ground snow load greater than 30psf, then additional analysis is required for side loading on the roof attachment and beam. 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, the Dead Load for your specific installation must be less than 5 psf, including modules and Unirac 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 Figure 3. Rail span and footing spacing are interchangeable. Paxe The Total Design Load, P (p€f) is determined using ASCE 7-05 2.4.1 (ASD Method equations 3,5,6 and 7) by adding the Snow Loadi, S (psf),Design Wind Load, pnet 0,€0 from Part I, Step 9 and the DeadLoad (psf). Both Uplift and Downforce Wind Loads calculated in Step 9 of Part 1 must be investigated. Use Table 7 to calculate the Total Design Load for the load 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). Use the following equations or Table 7. P (psD = 1.OD + 1.051 (downforce case 1) P 07€f) = 1.OD + 1.Opnet (downforce case 2) PO,€0 = 1.OD + 0.759 + 0.7*net (downforce case 3) P 07€f) = 0.6D + 1.Opnet (uplift) D = Dead Load (psf) S = Snow Load (psf) pnet = Design Wind Load (psf) (Positivefor downforce, negative for upiift) The maximum Dead Load, D (psf), is S esf based on market research and internal data. 1 Snow Load Reduction - Ihe snow load can be reduced according to Chapter 7 of ASCE 7-05. Ihe reduction is a Junction of the roof slope, Exposure Factor, Importance Factor and Thermal Factor.

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 responsibilitv to verifv that the buildinE structure is strong enousrh to supnort the point load forge Table 10.

PIC 18 SolarMount Unirac Code-Compliant Installation Manual :FUNIRAC [3.2.4] Installing SolarMount rails ,¢SR 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 I.I.--<*Fr---mthe 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 4always 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 thefooting bolt slots ofSolarMount rail sections. Mounting Rails on Footings: Rails maybe 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 4-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 shown in Figure 8,9, 11, or 12, whichever is appropriate.

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).

To ensure that the L-feet will be easily accessible during flush installation: Install Second • Use the PV module mounting holes nearest the ends of the modules. • Situate the rails so that footing bolt slots face outward. n 11 11 13 11 1' SolarMouHt Rails The single slotted square side of the L-foot must always lie against the roof with the double-slotted side perpendicular to the roof. Foot spacing (along the same rail) and rail overhang depend on design wind loads. Install half the L-feet: Lower 1 roof edge ¥ 0-· Instaft First . 11 - *- Rafters - 11 11 11 11 11 • 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 roofing into the center of the rafter at each lag screw hole location. Squirt sealant into the hole and onto the shafts of the lag screws. Seal the underside of the L-feet with a sealant. Securely fasten the L-feet to the building structure with the lag screws. Ensure that the L-feet face as shown in Figure 23 or Figure 24. Figure 23. Layout with rails perpendicular to rafters. Raftcrs , y .. .. 0. .. .. ..

Page 23 :1:UNIRAC Unirac Code-Compliant InstaUation Manual SolarMount [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 module glass. Align the edges of the modules and snug them together (Fig. 21, page 22). 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 the arrangement you selected earlier. Assemble the clips, mounting bolts, and flange nuts. Torque the flange nuts to 10 foot-pounds. [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 recom- mends safety lines whenever lifting one to a roof. Align the panel with the previously installed L-feet. Slide 3/8 inch L-foot mounting bolts onto the rail and align them with the L-feet mounting holes. Attach the panel to the L-feet and finger tighten the flange nuts. 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 modules. This may enhance perfor- mance in hotter climates. slol ooting OIl slot W-. Clip slots unling 'S Flange FI nut b Figure 25.

Slide the remaining L-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 "Laying out and installing L-feet" above. Torque all footing flange nuts to 30 foot-pounds. Verify that all lag bolts are securely fastened. .r 4'1 0 Page 24 SolarMount Unirac Code-Compliant Installation Manual :FUNIRAC [3.4] Installing SolarMount with grounding clips and lugs Clips and lugs are sold separately.
