Procedures for code-compliant installations using the SolarMount Module Mounting System This bulletin is designed to support, applications for build- ing permits for installations using SolarMount™ PV Module Mounting System, manufactured by UmRac, Inc Follow the six steps below and the installation instructions on pages 9-20 to install SolarMount in compliance with the 2001 California Building Code and the UBC1997 Before proceeding, note the following • This bulletin addresses only wind loads on the as- sumption that wind produces the maximum load factor affecting an installation Verify that other local factors, such as snow loads and earthquake effects, do not ex- ceed the wind loads Give precedence to any factor that does Wind loads are considered to act on the entire projected area, or may be perpendicular to any surface • The roof on which the SolarMount will be installed must have the capacity to resist the combined Design Dead Load and Live Load per footing listed m Tables 2 and 3 on pages 6-7 1. Determine the Basic Wind Speed at your installation site For the United States, see "Minimum Basic Wind Speeds in Miles per Hour," reproduced below If your installation is outside the United States or if you need further assistance, consult a local professional engineer or your local building authority Figure J Minimum Basic Wind Speeds Reproduced from UBC, Vol 2, Structural Engineering Design Provisions, Chap 16, Div III, Wind Design, Fig 16 1, "Minimum Basic Wind Speeds m Miles per Hour," p 36 The map has been adopted by the 2001 California Building Code (Fig 16-1, vol 2 p 36) 05/2007 Rev 15 *PM353030 40 of 179 SolarMount® Code-Compliant Planning and Assembly (California) U '•>-'•' TE C HC H N O l_t>0 I ES 2. Determine the exposure category of your installation site The California Budding Code* defines wind exposure catego- ries as follows EXPOSURE B has terrain with buildings, forests or sur- face irregularities covering at least 20 percent of the ground level area extending 1 mile (1 61 km) or more from die site EXPOSURE c has terrain that is flat and generally open, extending l/2 mile (0 81 km) or more from the site in any quadrant or having scattered obstructions extending one-half mde or more from the site in any full quadrant This category includes flat or gently rolling open country and grasslands Sites normally considered as Exposure B, but which are subject to topographic amplification or channelization, such as ndgetops or draws, shall be considered as Exposure C T EXPOSURE D represents the most severe exposure m ar- eas with basic wind speeds of 80 miles per hour (mph) (129 km/h) or greater and has terrain that is flat and unobstructed facing large bodies of water over 1 mile (1 61 km) or more in width relative to any quadrant of the building site Exposure D extends inland from the shoreline 1A mile (0 40 km) or 10 times the building height, whichever is greater 3. Determine Design Wind Pressure required for your installation Design Wind Pressure is the amount of wind pressure that a structure is designed to withstand, expressed here m pounds per square foot (psf) To determine the Design Wind Pressure required for your installation, apply the following factors using Table 1 • your Basic Wind Speed (determined in step 1), • your exposure category (determined m step 2) and • the height of your roof above the ground If your values fall significantly outside the range of the table, or if your Design Wind Pressure requirement exceeds 50 psf consult UniRac, a professional engineer or your local building authority Table I Design Wind Pressure (psf) by Wind Speed and Exposure Category Design force applies to surface pressure and/or uplift (withdrawal) Basic Wind Speed (mph) *2001 California Building Code, vol 2 chap 16, Structural Engineei ing Design Provisions, Div III Wind Design, p 3810 rEmphasis in the original, indicating material inserted by California into definitions adopted from the UBC Category B 1 5' roof height 20' roof height 25' roof height 30' roof height Category C 1 5' roof height 20' roof height 25' roof height 30' roof height Category D 15' roof height 20' roof height 25' roof height 30' roof height 70 10 1 1 12 12 17 19 19 20 23 24 25 25 80 13 14 15 16 23 24 25 26 30 31 32 33 90 17 18 19 21 29 31 32 33 38 39 41 42 100 21 22 24 25 35 38 40 41 46 48 50 51 110 25 27 29 31 43 46 48 50 56 58 60 62 120 30 32 35 36 51 54 57 59 67 70 72 74 130 35 38 41 43 60 64 67 69 78 82 84 87 Source These Design Wind Pressure (P) values are based on the formula P = Ce * C. * q. * lf (2001 California Building Code, voL 2, chap 16, Structural EngineermgDesign Provisions Dn- III WindDesign,p 3810) Assump- tions / = / and C = I 3 4a. Determine Minimum Design Dead and Live Loads for standard rafter spacing... Foot spacing refers to the space between L-feet (or standoffs, if applicable) along the same SolarMount rail (see Fig 2, p 8) If you are spacing feet to match a standard rafter spacing, con suit Table 2 to determine your Minimum Design Live and Dead Loads per footing (If you prefer to maximize foot spacing to minimize roof penetrations, skip to Step 4b on p 8 ) Locate the make and model of the PV module that you plan to install and the rafter spacing at your installation site Read the Minimum Design Dead Load and read or extrapolate the Mini- mum Design Live Load for the Maximum Foot Spacing and the Design Wind Pressure you determined in step 3 To meet code, you must verify that the roof rafter assembly at your installation site has the capacity to resist the sum of the Design Dead and Live Loads If they do not, try smaller footer spacing (In this case, you may elect to use the procedures outlined in Step 4b ) If the result is still not acceptable, relocate the array to a stronger area of the roof or strengthen the inadequate framing elements For assistance, consult a local professional engineer Go to step 5 on page 8 05/2007 Rev 15 •PM353030 41 of 179 SolarMount® Code-Compliant Planning and Assembly (California) Table 2 SolarMount® Loads (Ibs) per Footing at Standard Rafter Spacings To meet code, your Design Loads must be at or above those indicated You the installer are solely responsible for verifying that the roof can withstand these design loads For specifications based on Design Wind Pressure values greater than 50 pounts per square foot, contact UniRac Minimum Design Dead Load Minimum Design Live Load as a Function of Design Wind Pressure 20psf 30psf 40psf SOpsf Minimum Design Dead Load Minimum Design Live Load as a Function of Design Wind Pressure 20psf 30psf 40psf SOpsf 433 578 650 Sanyo HIP-I80BA3 thru -200BA3 48' rafter (foot) spacing 29 173 260 347 64" rafter (foot) spacing 39 231 347 462 72' rafter (foot) spacing 44 260 390 520 Sharp ND-NOECU (MOW) 48' rafter (foot) spacing 26 153 230 306 383 64" rafter (foot) spacing 34 204 306 408 5IO 72 rafter (foot) spacing 39 230 344 459 574 SharpND-l67U3 48' rafter (foot) spacing 28 174 262 349 436 64' rafter (foot) spacing 37 232 349 465 58! 72 rafter (foot) spacing 41 262 392 523 654 Sharp NT-I75UI,NT-I85UI 48' rafter (foot) spacing 35 207 3IO 4I3 5I7 64' rafter (foot) spacing 47 276 4I3 55! 689 72' rafter (foot) spacing 53 3IO 465 620 775 Sharp ND-200UI, ND-208UI 48' rafter (foot) spacing 21 64' rafter (foot) spacing 43 72' rafter (foot) spacing 48 SunWize SW85, SW90, SW95 48' rafter (foot) spacing 35 64 rafter (foot) spacing 46 72' rafter (foot) spacing 52 SunWize SW155, SW165 48 rafter (foot) spacing 28 64' rafter (foot) spacing 38 72 rafter (foot) spacing 43 273 393 5I3 634 337 486 634 783 379 546 7I4 NA 190 253 285 234 3I2 35! 285 380 474 380 506 633 427 569 7I2 339 452 508 444 592 666 549 732 NA 05/2007 Rev 15 •PM353030 42 of 179 SolarMount® Code-Compliant Planning and Assembly (California) SiittWJZe> TECHNOLOOIE« Table 3 SolarMount® Loads per Footing at Maximum Foot Spacing To meet code, your Design Loads must be at or above the Design Wind Pressure indicated You the installer are solely responsible for verifying that the roof can withstand these design loads For specifications based on Design Wind Pressure values greater than 50 pounds per square foot contact UniRac, Design Wind Pressure 20psf JOpsf 40psf 50psf Design Wind Pressure 20psf JOpsf 40psf 50psf Sanyo HIP-I80BA3 thru -200BA3 Maximum Foot Spacing (inches) Minimum Foot Design Live Load (Ibs) Minimum Foot Design Dead Load (Ibs) Sharp ND-NOECU (NOW) Maximum Foot Spacing (inches) Minimum Foot Design Live Load (Ibs) Minimum Foot Design Dead Load (Ibs) Sharp ND-I67U3 Maximum Foot Spacing (inches) Minimum Foot Design Live Load (Ibs) Minimum Foot Design Dead Load (Ibs) Sharp NT- 1 TSUI, NT- I85UI Maximum Foot Spacing (inches) Minimum Foot Design Live Load (Ibs) Minimum Foot Design Dead Load (Ibs) 125 451 76 133 424 72 124 450 71 114 491 83 102 553 62 108 516 58 102 556 58 93 601 68 88 636 54 94 599 51 88 639 50 81 698 59 79 713 48 84 669 45 79 717 45 72 775 53 Sharp ND-200UI.ND-208UI Maximum Foot Spacing (inches) Minimum Foot Design Live Load (Ibs) Minimum Foot Design Dead Load (Ibs) SunWize SW8S, SW90, SW95 Maximum Foot Spacing (inches) Minimum Foot Design Live Load (Ibs) Minimum Foot Design Dead Load (Ibs) SunWizeSWI55,SWI65 Maximum Foot Spacing (inches) Minimum Foot Design Live Load (Ibs) Minimum Foot Design Dead Load (Ibs) 102 535 68 119 470 86 101 494 60 88 668 59 97 575 70 87 614 52 77 763 51 84 664 61 76 763 45 65 772 43 75 741 54 68 777 40 7 05/2007 Rev 15 *PM353030 43 of 179 liNillAC* SolarMount® Code-Compliant Planning and Assembly (California) SUIlWiZf£ 4b.... Or verify Maximum Foot Spacing and Determine Minimum Design Dead and Live Loads To minimize roof penetrations, consult Table 3 (p 7) to deter- mine Maximum Foot Spacing allowable for the Design Wind Pressure that you determined in Step 3 Find the make and model of the PV module vou plan to install, then read or extrapolate Foot Design Live Loads and Dead Loads at the maximum spacing To meet code, you must verify that foot spacing is at or below the dimension listed and that the roof rafter assembly at your installation site has the capacity to withstand the sum of the Design Dead Load and Design Live Load for the speci- fied spacing If they do not, try smaller footer spacing If the result is still not acceptable, relocate the array to a stronger area of the roof or strengthen the inadequate framing elements For assistance, consult a local professional engineer 5. Verify acceptable Rail End Overhang Rail End Overhang (Fig 2) must equal 50 percent or less of foot spacing Thus, if foot spacing is 72 inches, the Rail End Overhang can be up to 36 inches In this case, two feet can support a rail of as much as 144 inches (72 inches between the feet and 36 inches of overhang at each end) 6. Ensure that Live Loads do not ex- ceed Pull-Out Capacities Based on the characteristics of your roof rafter or truss lumber and the lag screws, consult Table 4 to determine the lag pull- out capacity per 1-inch thread depth Compare that value to the minimum design live load per footing determined in Step 4a or 4b Based on these values, determine the length of the lag-screw thread depth you require to resist the design live load To ensure code compliance, the lag pull-out capacity per footing must be greater than the footing design live load If your SolarMount requires standoffs, always use at least two lag screws to secure the standoff to the rafter Figure 2 SolarMount foot spacing refers to the distance between feet on the same rail Over- hang, the distance from end of the rail to the first foot, may be no more than half the fool spacing Table 4 Lag pull-out (withdrawal) capacities (Ibs) in typical roof truss lumber Douglas Fir, Larch Douglas Fir, South Engelmann Spruce Lodgepole Pine (MSR I650f & higher) Hem, Fir Hem, Fir (North) Southern Pine Spruce, Pine, Fir Spruce, Pine Fir (E of 2 million psi and higher grades of MSR and MEL) Specific gravity 050 046 046 043 046 055 042 050 f/,<. shaft,* 2/4" thread depth 665 588 588 530 588 768 513 665 Lag screw specifications •V,t shaft* per 1 thread depth 266 235 235 212 235 307 205 266 '/t shaft,* per / thread depth ||r|jj 304 269 269 243 269 352 235 304 t : Thread depth i i .¥ J! ii!==i 353Smss=3=!=; ==: ^ ^ 1 V Sources Uniform Building Code American Wood Council Notes (/) Thread must be embedded in a rafter or other structural roof member (2) Pull-oul values incorporate a I 6 safety factor recommended by the American Wood Council (3) See UBC for required edge distances *Use flat washers with lag screws to, 8 05/2007 Rev 15 *PM353030 44 of 179 SolarMount® Code-Compliant Planning and Assembly (California) TECH NOLDOIES Part III.

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 pro- fessional 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 Secure the footings in accordance with "Installing L-feet" (p 11) Leave enough room to safely move around the array during installation The width of a rail-module as- sembly equals the length of one module Note that L-feet may extend beyond the width of the assembly b> as much as 2 inches on each side The length of

easily accessible during flush installation • Use the PV module mounting holes nearest the ends of the modules • Situate the rails so that foot- ing bolt slots face outward Use Figure 20 to determine spacing between feet on opposite rails Foot spacing (along the same rail) and rail overhang depend on design wind loads To meet code, you must use the foot spacing determined in procedural steps 4a or 4b (pp 5, 8) Install half the L-feet • If rails are perpendicular to rafters (Fig 21), install the feet closest to the lower edge of the roof • If rails are parallel to rafters (Fig 22) install the

must be tied together using a single grounding conductor The NEC also requires that a solar module should be able to be removed without breaking the grounding conductor for that string Each solar module will attach to the continuous ground using a tin-plated copper lay-in lug that is UL listed for outdoor use One lug will be fastened to the frame of each solar module using a 10-32 1/2" stainless steel screw A self-drilling 'tek' screw is not acceptable for this application This ground connection can be done while installing each solar module onto the supporting rails It will save time to fasten the lay-In lug onto each solar module frame prior to placement onto roof structure See drawings in this section In addition to grounding the solar modules, it is also necessary to bond all SolarMount rails together by attaching a lay-in lug on the side of each rail Once the lugs are installed, the extra grounding wire supplied with the ground kits can be use to interconnect the rails It is recommended that any exposed connections, such as the ground connections, should be coated with durable anti-oxidant coating Sizing of Equipment Ground Conductor The size of the grounding conductor that is not protected by GFDI (i e DC side) should be sized to be at least 125% of the short circuit currents originating from the photovoltaic source [NEC 690 45] The size of a grounding conductor that is of a source protected by GFDI (le AC side) the grounding conductor should be sized as per NEC table 250 122 DC Grounding Electrodes and Grounding Electrode Conductors In most

largest conductor on the DC side If the array is mounted away from the dwelling (e g ground or pole mounted), then an additional grounding electrode (DC side ground rod) may be required The DC side ground rod would be installed as close as possible to the PV array and the grounding electrode conductor would be sized according to [NEC 250 166] If a second ground rod is necessary, the two

recommended to have two persons lift the inverter into position on the Power Center or on the wall as it can weight up to 140lbs Once the inverter has been secured, complete the wiring into the inverter's wiring compartment Connect the solar array by installing 3/4" conduit to the DC Disconnect switch hub or knock-out When completing the wiring, it is recommended to leave a few extra inches of wires so that they can be quickly maintained in case the connection would corrode 05/2007 Rev 15 *PM353030 78 of 179 Main Service Panel The Mam Service Panel will need to have the physical space to accept an additional AC breaker to accommodate the GTS system Please refer to the Electrical Diagram supplied with your system or with the system diagram in Section 4 for the appropriate breaker size The Mam Service Panel sum of source current will also need to be kept under the busbar rating of the manufacturer If the system is installed in a dwelling, the NEC does allow the sum of current sources to exceed the rating of the busbar by more than 120% of the rating [NEC 690 64] If the existing service entrance is a 100A service, the additional PV breaker cannot exceed 20A and in a 200A service entrance, the breaker cannot exceed 40A If the additional breaker for the GTS system exceeds the 120% current headroom or does not have the physical space to be inserted in the panel, a sub-panel will need to be installed on the line side of the Service Panel 05/2007 Rev 15 *PM353030 79 of 179 Installation Chapter 2, "Installation", provides information about planning for and installing the GT Inverter It contains information to help you plan wire routes, AC and DC connections, and find a suitable location for installation It also discusses requirements for grounding the

GT Inverter may be installed as a single inverter for a single P V array of one or two PV strings, or in a multiple inverter configuration for multiple PV arrays (see Figure 2-1 for diagrams of both options) Single Inverter Installation In this configuration, a single inverter collects the harvested solar energy and routes the power to the mam utility service panel to be used by the loads Any surplus power not used by the loads will be directed to the utility grid Multiple Inverter Installations If multiple inverters are used, each inverter must be wired to an independent PV array In this configuration, each inverter collects the harvested solar energy from a separate PV array and routes the power to the mam utility service panel to be used by the loads Any surplus power not used by the loads will be directed to the utility grid Communications between inverters can be enabled by installing network cabling to the inverter RJ45 ports See "Connecting Network Cable Between Multiple Inverters" on page 3-16 Planning the Installation The following issues need to be considered when planning for an installation using the GT Inverter See the specified sections for more information

All wiring should be sized correctly to minimize voltage drop All exposed wires or conduits should be sunlight resistant All required overcurrenl protections should be included in the system and accessible for maintenance Depending on the installation, an external disconnect may be required if the inverter is installed in a location not easily accessible to utility or fire personnel Consult local authorities for additional information Integral roofing products should be properly rated All electrical terminations should be fully tightened, secured, and strain relieved as appropriate All mounting equipment should be installed according to the manufacturer's specifications All roof penetrations should be sealed with an acceptable sealing method that does not adversely impact the roof warranty All wires, conduit, exposed conductors and electrical boxes should be secured and supported according to code requirements 975-0245-01-01 2-5 05/2007 Rev 15 *PM353030 84 of 179 Installation Voltage and MPPT Requirements MPPT operational window The MPPT software maximizes the output energy of solar arrays as long as the operating voltage is within the MPPT operational window Ensure that the PV array used in the system operates within the MPPT operational window Effects of array voltages outside of the MPPT operational window are shown in Table 2-1 Table 2-1 MPPT Voltage < 195 Vdc 195to550Vdc 550 to 600 Vdc "> 600 Operational Window Effect of Array Voltage Operating voltage will be shifted to 195 Vdc, the array will not be at its maximum power point Maximum harvest of solar energy Will not allow maximum harvest of solar energy Will shut down and may cause damage to the inverter, stops selling surplus energy Inverter Mode Low power MPPT window Power derating Shutdown Voltage The maximum power point voltage of a string connected to the GT Inverter should requirements be a minimum of 195 Vdc If it is less than 195 Vdc, the inverter will continue to operate, but it will regulate the PV voltage to 195 V Because the array will not be operating at its maximum power point, this may result in lower than expected energy harvest Maximum PV The solar array should be sized such that its maximum power output docs not Power exceed the limits of the MPPT operational window (195 to 550 Vdc) See "Guidelines for Matching PV Array Size to Xantrex Grid Tie Solar Inverter Input" The array voltage should never exceed 600 VOc (open circuit voltage) under any thermal condition Likewise, ensure that the Isc (short circuit current) rating of the array at any temperature does not exceed the short circuit current rating of the inverter 2-6 975-0245-01-01 05/2007 Rev 15 •PM353030 85 of 179 Planning the Installation Guidelines for Matching PV Array Size to Xantrex Grid Tie Solar Inverter Input For determining the number of panels required in the PV string (panels connected in series), you must ensure that the following requirements are met 1 To avoid damage to the inverter, ensure that the PV array output will never exceed 600 Vdc under any conditions 2 Do not exceed the maximum array short circuit-current rating marked on the inverter 3 To achieve maximum energy harvest from your array, ensure that the VMP (voltage at maximum power) does not drop below 195 Vdc or increase above 550 Vdc under most conditions Guidelines to help you meet these requirements • Consider the expected VOc of the string under all possible conditions The panel manufacturer provides a VOc rating per panel, but it is usually rated at 25°C (77°F) Ensure that the VOc rating at the coldest ambient temperature does not exceed 600 Vdc Panel voltage increases in cold temperatures—the panel manufacturer should be able to provide a coefficient of voltage increase per degree The NEC also has required temperature/voltage deratings that must be used, these can be found in Table 690 7 of the 2002 NEC handbook You need to determine the coldest temperatures expected on the site, and size the array strings accordingly The array's maximum DC voltage in coldest expected temperature, with both manufacturer coefficient and NEC derating, must not exceed 600 Vdc to prevent inverter damage • Panel voltage decreases in high temperatures This will affect the panels' VMP. Again, the manufacturer's coefficient must be used with the highest expected temperature to determine the minimum VMPL Once you know the specifications of your panels, all these factors will help determine the maximum and minimum number of panels that can be used Note The GT PV array sizing tool is available at www xantrcx com 975-0245-01-01 2-7 05/2007 Rev 15 *PM353030 86 of 179 Installation Grounding Requirements AC Grounding North America Elsewhere PV Grounding WARNING: Shock hazard The GT Inverter must be grounded by connection to a grounded permanent wiring system The GT Inverter must be connected to a grounded, permanent wiring system via the GT Inverter ground bar See Figure 2-2 for the location of the GT Inverter ground bar The ground bar must also be connected to the main utility breaker panel ground bar and to the house grounding rod according to NEC requirements In other locations, AC grounding is governed by local codes Consult with the local utility for specific grounding requirements The GT Inverter is designed to have all PV positive, negative, and ground conductors connected inside its wiring box The PV equipment ground should be connected to the GT Inverter ground bar The size for the conductor is usually based on the size of the largest conductor in the DC system A DC grounding electrode conductor may be required by the Authority Having Jurisdiction (AHJ) Use the GT Inverter ground bar for this connection Important In most models, the negative PV conductor is internally bonded to the ground system within the inverter's ground fault detection circuit Inverter models marked with the "-POS" suffix are positive grounded and have the positive PV conductor internally bonded to the ground system through the inverter's ground fault protection circuit It is important that the negative (or positive) PV conductor is not bonded to the ground at any other point in the system Long Distance Grounding If the PV array is more than 30 meters (100 feet) from the inverter, then there must also be a direct connection from the array frame to an earth ground next to the array A connection between this ground and the primary earth ground connection via a buried wire between the two points is also necessary (see Figure 2-3) 2-8 975-0245-01-01 05/2007 Rev 15 *PM353030 87 of 179 Planning the Installation Lightning Protection Reduce the risk of lightning damage by using a single-point grounding system In this system, all ground lines terminate at the same point—the primary earth ground This point normally is the mam utility ground installed by the utility company to provide a ground for the house wiring (see Figure 2-4) This ground usually consists of a copper rod driven 1 5 to 2 5 meters (6 to 8 feet) into the earth PV Array Main Utility Service Panel L1 BD L2 (NEUTRAL :",-=:~ivr^'?- •:.v'.."v:.y.'?.'i...!
