MeTrac @ Installation Manual Date Modified: 09/12/07 For installations requiring more than one row, with no spacing between rows, the distance between adjacent rail pairs will measure approximately the length of the module less 48". Snap chalk lines along the location of where the support rails will be placed once spacing is calculated and measured. 48„ Actual spacing will be deter- mined on pattern of the roofing material to ensure a proper seal. Locating roof rafters along chalk lines 1) Since rafters are normally located every 48" on center (o/c), finding one reference rafter should be sufficient for approximating the lo- cation of additional rafters by measuring 48" from the center of the first. 2) If the roof eve (bottom edge of roof) is ex- posed, reference the bottom edge of the roof rafter location and use to approximate the lo- cation of the roof rafter/intersection chalk line on the upper section of roof. (EASIEST FOR TILE ROOF) tf the roof has a closed or blind soffet (enclosed rafters not visible at roof edge), - the nailing pattern along the fascia board (board attached to ends of rafters) may indi- cate the rafter location at the bottom edge of the roof.

' SML System Code-Compliant Planning and Assembly Installation Manual Part I. Scope, components, and installer responsibility [1.1.] Introduction The SunPower SML System Code -Compliant Installation Instructions support applications for building permits for photovoltaic arrays using SunPower PV module mounting systems.

Use two per row of modules. 6105-T5 aluminum extrusion, anodized. © Rail splice — Joins rail sections into single length of rail. It can form either a rigid or thermal expansion joint, 8 inches long, predrilled. 6105-T5 alununum extrusion, anodized. © Self -drilling screw — (No. 10 x 5/8") — Use 4 per rigid splice or 2 per expansion joint. 18-8 stainless steel. OL -foot — Use to secure rails to standoffs. Refer to loading tables for spacing. Use no less than one L -foot per 4 feet of rail. 6105-T5 aluminum extrusion, anodized. © L -foot bolt (3/8" x 3/411) — Use one per L -foot to secure rail to L -foot. 304 stainless steel.

Includes 3/9'x 3/4" serrated flange bolt with EPDM washer for attaching L -foot, and two 5/16'x 31/2' lag bolts. Flashings: Use one per standoff. SunPower offers mutiple flashings. QLag screw for L -foot (5/16" x 3.5") — Attaches standoff to rafter. OTop Mounting Clamps (' Top Mounting Grounding Clip and Lug Installer supplied materials: • Waterproof roofing sealant — Use a sealant appropriate to your roofing material. SML System Code -Compliant Planning andAssembly Installation Manual [3.3.] Installing SML System 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 SML System splice bars, attach the rails together (Fig. 9) before mounting the rails to the footings. If using more than one splice per rail, contact Sunpower concerning thermal expansion issues. Mounting Rails on Footings. Rails may be attached to either of two mounting holes in the L -foot (Fig. 10). 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'/s-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 7 or 8, whichever is appropriate. Aligning the Rail Ends. Align one pair of rail ends to the edge of the installation area (Fig. 11 or Fig. 12). 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. 11), 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. 12), 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. I - Edge of installation area Figure 11.

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 a return 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.14). Finger tighten the flange nuts, center and align the module as needed and securely tighten the flange nuts (15 ft lbs) 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. 11im the second module face up (Fig. 13). 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. 15).1 For a neat installation, fasten, wire management devices to rails with self -drilling screws.
