Unirac also provides a limited warranty on SolarMount products (page 26). ; A 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 thetoughest challenges. Which is why SolarMount isPV's most widely used mounting system. • 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. l 2 . SolarMount Unirac Code -Compliant Installation Manual d°UNIRAC 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 2006. 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 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 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 of these procedures is subject to the following 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. S. 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 for more clarification on the use of Method I. Lower design wind loads may be obtained by applying Method 11 from ASCE 7-05. Consult with a licensed engineer if you want to use Method 11 procedures. The equation for determining the Design Wind Load for components and cladding is: pnet (PSD = AKitlpnet3o poet (psf) = Design Wind Load A = adjustmentfactorfor height and exposure category Ke, =Topographic Factor at mean roof height, h (ft) 1= Importance Factor pnet$o (psj) = net design wind pressurefor Exposure B, at height =30,1=1 You will also need to know the following information: Basic Wind Speed = V (mph), the largest 3 secondgust of wind in the last 50years. h (ft) = total roof height for flat roof buildings or mean roof height for pitched roof buildings Effective Wind Area (sf) = minimum total continuous area of modules being installed Roof Zone = the area of the roofyou are installing the pv system according to Figure 2, page 5: Roof Zone Setback Length = a (ft) 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 [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. be installing.This is the smallest area tributary ary (contributing load) to a support or to a simple -span of rail. That area is the Step 1: Determine Basic Wind Speed, V (mph) Effective Wind Area, the total area of the fewest number of modules on a run of rails. 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.

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 Exposure Categories. The ASCH/SEI.7-05' defines wind exposure categories as follows: EXPOSURE a is urban and suburban areas, wooded areas, or other terrain with numerous closely spaced obstructions having the size of single family dwellings. EXPOSURE 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. EXPOSUR12 D has flat,, unobstructed areas and water surfaces outside hurricane prone regions. This catego- ry includes smooth mud flats, salt flats, 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. rt..

Procedure to Select Rail Span, and Rail Type [2.1.] Using Standard Beam Calculations The procedure to determine the Unirac SolarMoun't 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 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. 1 Figure 3. Rail span and footing spacing are interchangeable. Ravi w. 10 S- S I Structural Engineering Methodology Step I!: Determine the Total Design Load The Total Design Load, P (psf) is determined using ASCE 7-05 2.4.1 (ASD Method equations 3,5,6 and 7) by adding the Snow Loads, S (psf), Design Wind Load, poet (psf) from Part 1, Step 9 and the Dead Load (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 11, Step 6). 1 P (psf) = LOD + LOSI (downforce case 1) P (psj) LOD + I.Opnet (downforce case 2) I P (psj) = LOD + 0.75SI + 0.75p,w (downforce case 3) 1 P (psf) L 0.6D + Lopnn (uplift) I D = Dead Load (psf) S = Snow Load (psf) Net = Design Wind Load (psf) (Positive for downforce, negative for uplift) The maximum Dead Load, D (psf), is 5 psf based on market research and internal data. I Snow Load Reduction - The snow load can be reduced according to Chapter 7 ofASCE 7-05. The reduction is afunction of the roof .slope, Exposure Factor, Importance Factor and Thermal Factor.

Use the maximum absolute value of the three downforce cases and the Uplift Case. We assume each module is supported by two rails. w = PB/2 w,= Distributed Load (pounds per linearfoot, plf) B = Module Length Perpendicular to Rails (ft) P = Total Design Pressure (pounds per square foot, psf) Table 8.

Foreign matter will cause bolts to bind as they slide in the slots. 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. Although structural, thejoint 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.) If using more than one splice per rail, contact Unirac concerning 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 for a higher profile, which will maximize airflow under the modules. This will cool them more and may enhanceperformance in hotter climates. Slide the''/, -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. Aligning the Rail Ends. Align one pair of rail ends to the edge of the installation area (Fig. 15 or Fig. 16). Figure 13. Splice bars slide into the footing bolt. slots of SolarMount rail sections. Clamping bolt slot Footing bolt slot The opposite pair of rail ends will overhang the side of the installation Figure 14. 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 (20 fc 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 -I a I I I Figure 15.

If modules are the Plug and Play type, no pre -wiring is required, and you can proceed directly to "Installing the First Module" below. If modules have standard J-boxes, each module should be pre -wired with one end of the intermodule cable for ease of installation. For safety reasons, module pre -wiring should not be performed on the roof. Leave covers off J-boxes. They will be installed when the modules are installed on the rails. Installing the First Module. In high -profile installations, the safety bolt and flange nut must be fastened to the module bolt slot at the aligned (lower) end of each rail. It will prevent the lower end clamps and clamping bolts from sliding out of the rail slot during installation. If there is areturn cable to the inverter, connect it to the first module. Close the J-box cover. Secure the first module with T-bolts and end clamps at the aligned end of each rail. Allow half an inch between the rail ends and the end clamps (Fig.18). Finger tighten flange nuts, center and align the module as needed, and securely tighten the flange nuts (5-10 ft Ibs). Installing the Other Modules. Lay the second module face down (glass to glass) on the first module. Connect intermodule cable to the second module and close the J-box cover. Turn the second module face up (Fig. 17). With T-bolts, mid -clamps and flange nuts, secure the adjacent sides of the first and second modules. Align the second module and securely tighten the flange nuts .(Fig.19). For a neat installation, fasten wire management devices to rails with self -drilling screws. Repeat the procedureuntil all modules are installed. Attach the outside edge of the last module to the rail with end clamps. Trim off any excess mil, being careful not to cut into the roof. Allow half an inch between the end clamp and the end of the rail (Fig. 18). Check that all flange nuts on T-bolts are torqued to 5-10 ft Ibs Figure 17 I /2" minimum - Module frome �. 1/4"module bolt ^and.flonge.nut U0011 Rail, End clamp Figure 18 Figure 19 Module frames /4" module bolt EMI'd onge nut- Roil mp High -lipped module --- - -- --- "- - -- Spacer Low -lipped module (cross section) a (cross section) 1 —%-iI Solar u i rail SolarMa I i. rail Figure 20.

Fooling boll slot Bottom mounting clip C Stainless steel hardware can seize up;a process called galling. To significantly reduce its likelihood, (1) apply lubricant to bolts, preferably an anti -seize lubricant, available at auto parts stores, (2) shade hardware prior to installation, and (3) avoid spinning on nuts at high speed. See /nstallation Supplement 910, Galling and Its Prevention, at www.unirac.com. 0.n 21 :: UNIRAC UniracCode-CornpliantlnstallationManual SolarMount [3.3.1] Planning the installation area Decide on an arrangement for clips, rails, and L-feet (Fig. 22) Use Arrangement A if the full width of the rails contacts the module. Otherwise use Arrangement B., Caution: Ifyou choose Arrangement B, either (1) use the upper mounting holes of the L feet or (2) be certain that the L feet and clip positions don't conflict. If rails must be parallel to the rafters, it is unlikely that they can be spaced to match rafters. In that case; add structural supports — either sleepers over the roof or mounting blocks beneath it. These additional members must meet code; if in doubt, consult a professional engineer. Never secure the footings to the roof decking alone. Such an arrangement will not meet code and leaves the installation and the roof itself vulnerable to severe damage from wind. Leave enough room to safely move around the array during installation. The width of a rail -module assembly equals the length of one module. Note that L-feet may extend beyond the width of the assembly by as much as 2 inches on each side. The length of the assembly equals the total width of the modules.

Clip Arrangements A and B SolarMount Unirac Code -Compliant Installation Manual ::' U N I RAC [3.3.2] Laying out the installing 1-feet- L-feet are used for installation through existing low.p'rofile roofing material, such as asphalt shingles or sheet metal. They are also used for most ground mount installations. To'ensure that the L-feet will be easily accessible during Flush installation: • Use the P.V module mounting holes nearest the ends of the modules. • Situate the rails so that footing bolt slots face outward. 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 theL-feet: • If rails we 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. Hold the rest of the L-feet and fasteners aside until the panels are ready for the installation.

Align the edges of the modules and snug them together (Fig. 21, page22). 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 5 foot-pounds. Wire the modules as needed. For safety reasons, module wiring should not be performed on a roof. Fora neat installation, fasten cable clamps to rails with self -tapping screws. [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). Clip slots boll Mounting • Mount in the lower hole for a low, more aethetically Figure 25. Leg-ro-rail attachment pleasing installation. • Or mount in the upper hole to maximize a cooling airflow under the modules. This may enhance perfor- mance in hotter climates. Adjust the position of the panel as needed to fit the installa- tion area. 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.
