Based on the above information we have evaluated the structural capacity of the existing roof system to support the additional loads imposed by the solar panels and have the following comments related to our review and evaluation: Description of Residence: The existing residence is typical wood framing construction with the roof system consisting of truss system with all chords constructed of 2 x 4 dimensional lumber at 24”on center.The attic space is unfinished and photos indicate that there was free access to visually inspect the size and condition of the roof rafters.All wood material utiliz ed for the roof system is assumed to be Doug-Fir 2 or better with standard construction components.The existing roofing material consists of composite asphalt shingles. A.Loading Criteria Used 115 MPH wind loading based on ASCE 7-10 Exposure Category B”at a slope of 22 degrees 7 PSF Dead Load roofing/framing Live Load 20 PSF Ground Snow Load 45 PSF 3 PSF Dead Load solar panels/mounting hardware Total Dead Load 10 PSF The above values are within acceptable limits of recognized industry standards for similar structures in accordance with the 2012 IRC),2010 NYS Residential Code.Analysis performed of the existing roof structure utilizing the above loading criteria indicates that the existing rafters will support the additional panel loading without damage,if installed correctly. Page 2 of 2 B.Solar Panel Anchorage 1.The solar panels shall be mounted in accordance with the most recent Unirac Installation Manual”, which can be found on the Unirac website http://unirac.com/resources/).If during solar panel installation,the roof framing members appear unstable or deflect non-uniformly,our office should be notified before proceeding with the installation. 2.Maximum allowable pullout per lag screw is 235 lbs/inch of penetration as identified in the National Design Standards NDS)of timber construction specifications for Doug-Fir North Lumber) assumed.Based on our evaluation,the pullout value,utilizing a penetration depth of 2 is less than what is allowable per connection and therefore is adequate.Based on the variable factors for the existing roof framing and installation tolerances,using a thread depth of 2 with a minimum size of 5/16”lag screw per attachment point for panel anchor mou nts should be adequate with a sufficient factor of safety. 3.Considering the roof slopes,the size,spacing,condition of roof,the panel supports shall be placed no greater than 48”o/c. 4.Panel supports connections shall be staggered to distribute load to adjacent rafters. Based on the above evaluation,it is the opinion of this office that the standard installation will adequately support the additional loading imposed by the solar panels.This evaluation is in conformance with the 2012 International Residential Code,2010 NYS Residential Code,current industry standards and practice,and based on information supplied to us at the time of this report.

Reference and Tips Additional tips and information for installing mounts: n See Quick Tips videos on nail removal, and more at: http://www.quickmountpv.com/support/videos.html n It is not necessary or advisable to use nails or other fasteners to secure the perimeter of the flashing. n The L-Mount is made to work with standard and high-definition composition/asphalt and wood shingle roofs with 5" to 5-5/8" courses. If the exposed surface of the course exceeds this measurement you may need to use our Classic Shake Mount instead. n Depending on the season and climate, size and location of seal tabs, and quality of the shingles, the seal tabs that adhere the shingle courses together may not effectively seal the shingles to the flashings. If this is the case, simply add several quarter-sized dabs of manufacturer accepted sealant or asphalt roofing cement, meeting ASTM D 4586 Type II, between the flashing and the shingle above. n Mounts should not be installed in areas of the roof susceptible to ice damming. Water ponding under the shingles can reach the bolt penetration. n Take care not to damage the roofing material while working on the roof. Removing stone granules and deforming the shingles in any way can shorten the lifespan of the roofing. The value of the solar array is directly affected by the condition of the roof it is attached to. 925-478-8269 | www.quickmountpv.com | info@quickmountpv.com 2700 Mitchell Dr. | Walnut Creek, CA 94598 2018 by Quick Mount PV.

Document #508988 RevH 12 SunPower Proprietary 2.0 Listings, Compatibility, and Classification The SunPower InvisiMount Residential Mounting System is UL 2703 Listed. The InvisiMount Listing includes the following SunPower InvisiMount-compatible 96- and 72-cell modules, which are the only modules that are compatible with the InvisMount system: DC Modules AC Modules* SPR-X22-360 SPR-X21-345 SPR-X21-335-BLK SPR-E20-327 SPR-E19-320 SPR-X22-360-C-AC SPR-X21-345-C-AC SPR-X21-335-C-AC SPR-X21-335-BLK-C-AC SPR-X20-327-BLK-C-AC SPR-E20-327-C-AC SPR-E19-320-C-AC SPR-X20-327-C-AC Important! This guide assumes you are installing DC modules on the InvisiMount system; if you are installing AC modules on InvisiMount, do not use this guide—instead use the Equinox Installation Guide. Grounding from the module to the rail is accomplished through both the mid clamp and end clamp. The Listing also includes the following components, which have been evaluated for both mounting and bonding in accordance with UL 2703: end clamp mid clamp rail splice and splice screw ground lug assembly L-foot Row-to-row (R2R) grounding clip Document #508988 RevH 13 SunPower Proprietary 2.1 Fire Classification The maximum distance between the roof deck and the bottom of the module frame is 7.6 cm (3”). In order to maintain the system classification, this assembly must be mounted over a fire resistant roof covering for the application. The system achieves a Class A fire rating when installed with modules having a Type 2 fire classification. The system achieves a Class A fire rating when installed in the manner specified in these instructions. The system was evaluated for use on roofs having a pitch 2/foot (greater than or equal to 2:12). 3.0 System Ground Path The InvisiMount system features: Integrated module-to-rail as well as adjacent-module bonding (achieved through the mid clamp and end clamp). Integrated rail-to-rail bonding (achieved through the self-drilling splice screws and the splice). System bonding achieved through the equipment ground conductor (EGC). For arrays where the installer chooses to use row-to-row (R2R) grounding clips (refer to Section 5.6.1) instead of additional ground lugs and copper wire, system bonding is achieved through the R2R clips. The following two diagrams illustrate the key grounding and bonding aspects of the InvisiMount system for DC modules with and without the R2R grounding clip: the system ground path each component each bonding point the applicable NEC and UL references Document #508988 RevH 14 SunPower Proprietary Document #508988 RevH 15 SunPower Proprietary Document #508988 RevH 16 SunPower Proprietary 4.0 Installation Outline 1.

The SunPower Design Tool determines the actual span between attachments for a given system. Designers can access the Tool by logging into the Partner Portal and then clicking the Design Tool link. The Tool yields all the racking–specific structural calculations that can then be provided to the AHJ and that are typically part of the permitting process. Ensure that you bring the PDF file from the Design Tool output to the site! It is acceptable to attach either to the rafters or to the roof deck. SunPower recommends the following attachments, each of which is integrated into the Design Tool for easy design and permitting: For rafter attachment: SunModo K10068-BK8 (SunPower #508329) For deck attachment: SunModo K10068-BK7 (SunPower #508330) Instructions for installing the above attachments can be found here: sunmodo.com/wp-content/uploads/2015/04/D10011-V002-Guide-EZ-Roof-Mount.pdf Document #508988 RevH 17 SunPower Proprietary For curved and flat tile roofs, SunPower recommends Quick Mount PV QMHSS (SunPower #510083), which is also integrated into the SunPower Design Tool. Installation instructions can be found here: www.quickmountpv.com/support/videos/qhk-quick-install.html 5.1 Module Spacing The spacing between the modules shall be as follows: Intra-row spacing (side to side in a typical row): spacing is governed and enforced when the mid clamps are installed, and is 20 mm (0.8”). Row-to-row spacing (between an upper and a lower row in a typical array); spacing is governed and enforced when the row-row (R2R) spacers are installed, and is 20 mm (0.8”). 5.2 Attachment Span and Rail Cantilever The maximum distance (span) between roof attachments (L-feet or other attachment type) is 2.4 m (8). The maximum rail overhang distance (cantilever) is 1/3 of the maximum span: 0.8 m (32). Note: A spliced rail does not require any special allowance for span nor cantilever. Document #508988 RevH 18 SunPower Proprietary 5.3 Join Rails Depending on the roof slope and other factors, you may instead decide to join rails on the ground before transporting them to the rooftop. The rails and the splices have pre-drilled holes for the splice screws. You install one screw in each end of the splice (one screw per rail) (Fig. 1). Important! The splice is an integral part of the ground path. There must be no interference between the splice screws and the L-feet. Therefore, ensure that the splice screws will not interfere with your eventual attachment of the rail to the L-feet (refer to Fig. 6 and Fig. 7). 1. Fit a splice halfway into a rail end, align the splice hole with the rail hole, secure the components so that they will not move, and then drive a splice screw through the aligned hole stopping 1/3 turn after the screw face has contacted the rail face (Fig. 2). This method provides 4.5 N-m (40 +5/0 in-lbs) of torque. Use a torque wrench to verify and (if necessary) apply final torque to each screw. Splice screws are single use. If a screw becomes dull or prevents smooth, consistent penetration of the splice, use a new screw in the original hole. If a screw breaks, use the other hole that is provided—do not reuse the original hole. Ensure that you deburr the new hole. 2. Fit the second rail all the way onto the splice protruding from the first rail, align the respective holes, and install the second screw. The rail holes and splice holes must be aligned; the rail ends are not required to be in contact with each other. The maximum distance between a spliced rail pair is 6.4 mm (1/4). Fig. 1 Fig. 1 Fig. 2 Document #508988 RevH 19 SunPower Proprietary 5.4 Install Flashings, Roof Attachments, and Rails 1. Define the installation zone and array layout on the rooftop and mark it for penetrations as necessary. 2. Referring both to the flashing (if appropriate for the roof type) and to the attachment manufacturer guidance: a. Install the flashings and the roof attachments. b. Attach an L-foot to each of the roof attachments according to the method described by the attachment manufacturer guidance. Leave the hardware finger-tight for the moment. 3. Position the rails on the roof, adjacent to the L- feet and such that the side channel of each rail is facing the roof peak (Fig. 3 and Fig. 5). Important! To ensure precise alignment with the finished array’s footprint (perimeter), cut rails only after you have adjusted them to an even height and fully secured them to the attachments. 4. For each rail, determine the number of L-feet to which it will attach, and then slide that number of bolts into the rail’s side channel (bolt heads fit into channel; Fig. 4). Important! For your roof attachment strategy, remember that a spliced rail is the same as a solid rail in that a spliced rail does not require any special allowance in terms of overhang or attachments. Fig. 3 Fig. 4 Document #508988 RevH 20 SunPower Proprietary 5. Position the rail—with its side channel facing toward the peak—adjacent to and “below” relative to the peak) the L-feet for the given row Fig. 5). Note: L-feet must only “face” the peak (Fig. 5 and Fig. 6). 6. L-feet (or any other attachment type) must be positioned such that the L-foot-to-rail bolt is a minimum of 5 cm (2) from the end of a rail (Fig. 6); and a minimum of 5 cm (2) from any rail joint (Fig. 7). Fig. 5 Fig. 6 Fig. 7 Document #508988 RevH 21 SunPower Proprietary 7. Attach the rail to the L-feet by fitting the rail bolts through the slots on the L-feet and then temporarily finger-tightening an M10 nut on each of the bolts. (You apply torque to these nuts in Step 9.) Best Practice: Position each bolt at the midpoint of the vertical slot in its L-foot (Fig. 8). This will provide the greatest vertical adjustment flexibility. 8. To ensure that the installed modules will appear as an even plane, SunPower recommends that you use a string line and level (or other method) to ensure that the top surface of the rails is even Fig. 9). 9. After you are satisfied that the rails are level, tighten each L-foot nut to 42 +2/0 N-m (375 20/0 in-lbs). Note: The L-feet should still be only loosely attached to the roof attachments. 10. Tighten all of the L-foot-to-roof-attachment hardware according to the attachment manufacturer guidance. (If you are not using L- feet, tighten the attachment hardware according to the attachment manufacturer guidance.) Fig. 8 Fig. 9 Document #508988 RevH 22 SunPower Proprietary 5.5 Attach Ground Wire For arrays with two or more rows, before proceeding, decide now whether to use the R2R grounding clip (Fig. 10 and Section 5.6.1); or the additional ground lug assembly and copper wire Fig. 11) in order to achieve row-to-row grounding described in this section). Whichever method you choose, you must still install one ground lug assembly on one of the rails in the first row (Fig. 10). If your array has a standalone module (refer to Section 5.7), you must install a ground lug assembly on one of its rails as well. Important! Ensure that you install the system such that the copper ground wire will never contact any aluminum! (Refer to Fig. 16.) Fig. 10 Fig. 11 Document #508988 RevH 23 SunPower Proprietary 1. Slide the lug’s rail nut (Fig. 12) into the end of the top channel of a rail and position it where you want to attach the ground wire (you can disassemble the ground lug first if necessary). 2. Position the washer directly over the rail nut Fig. 13), and then use the M6 bolt to attach the lug to the rail nut by first orienting the lug parallel to the array (Fig. 14), finger-tightening the M6 bolt, and then using a 10 mm deep socket to apply an additional 5/6 of a turn only Fig. 15). Doing so provides 9.6 N-m (85 +5/0 in- lbs) of torque. After tightening in this manner, verify the value with a torque wrench. Fig. 12 Fig. 13 Fig. 14 Document #508988 RevH 24 SunPower Proprietary 3. Attach the copper ground wire to the lug as per NEC. Tighten the lug bolt (refer to Fig. 13) to 4 N- m (35 in-lbs). As you add modules, reposition the ground wire as necessary such that it will remain below the module frames but above the rails and will never contact the module frames or the rails! Best Practice: Because it is possible that, over time, the ground wire may inadvertently come into contact with a rail or other system component, attach another ground lug assembly to the rail and route the ground wire through it, to act as a spacer/retainer and help ensure that the ground wire remains securely in the position in which you installed it. 4. Following standard construction practices and the NEC, connect the array ground wire to the building’s ground. Warning! The ground wire must never be any closer to any other metal than 0.6 cm (1/4) (Fig. 16). Fig. 15 Fig. 16 Document #508988 RevH 25 SunPower Proprietary 5.6 Install Modules Important! If you are installing the rail-mounted J- box (Appendix A), do so now before installing modules. If your wire management strategy includes the DC rail clips (Appendix C), it is easiest to install them before you install modules. This section describes installing SunPower DC modules on the InvisiMount system. Rails may be positioned in the green (non-crosshatch) regions only, as follows: Size Tolerances 96 cell All sides: Minimum of 5 cm (2) but not more than 40.6 cm (16) from any module corner (Fig. 17 and Fig. 19). 72 cell Short side: Minimum of 5 cm (2) but not more than 25.3 cm (10) from any module corner (Fig. 18 and Fig. 20). Long side: Minimum of 5 cm 2) but not more than 40.6 cm (16) from any module corner (Fig. 18 and Fig. 20). Fig. 17 Fig. 18 Document #508988 RevH 26 SunPower Proprietary Fig. 19 Fig. 20 Document #508988 RevH 27 SunPower Proprietary Warning! Do not step on, stand on, or walk on the modules or the module frames, and do not place anything on them—even for a moment. 1. Position the first module of the row atop and at the end of the rails. 2. With the SunPower logo upward and the engagement mechanism downward, insert an end clamp into each of the rail ends by holding the clamp with your thumb and middle finger, and pressing on the bolt head with your index finger as you slide the clamp as far into the rail as possible (Fig. 21). If the clamp does not slide in easily, push on the bolt head. 3. Fit the top lip of the end clamp cover up and over the bottom edge of the module frame (Fig. 22). Do this for both end clamps. Verify correct module position and full end clamp engagement, and then tighten each end clamp bolt to 85 +5/0 in-lbs with a 10 mm socket. Note: If you need to remove an end clamp, first loosen its bolt two turns and then tap on its bolt head to free its engagement mechanism. 4. Fit one mid clamp down into the top channel of each of the row’s two rails, rotate it 90° (Fig. 23), and slide it toward the first module. Leave the two mid clamps loose for now. 5. Position the second module next to the first module. 6. For each of the two mid clamps: fit one side (two teeth) of each clamp over the respective adjacent frame edge of each of the two modules the first and second modules) (Fig. 24; second module not shown). Fig. 21 Fig. 22 Fig. 23 Document #508988 RevH 28 SunPower Proprietary 7. Tighten each of the two mid clamps to 9.6 N-m 85 +5/0 in-lbs). Important! Each mid clamp’s four teeth must solidly engage the module frames to ensure continuity of the module–rail ground path (Fig. 28). 8. Repeat Steps 4–7 until you have installed all except for the last module in the row. 9. For the last module in the row, position it on the rails in the desired location, and then mark a cut line on each of the rails at the module edge (Fig. 25). 10. Remove the module to ensure it is not damaged in the cutting process, and then cut the rails along the lines you marked. Important! The maximum distance the module is permitted to overhang the rail is 0.6 cm (1/4) Fig. 26). 11. Place the module in position again and then add its two mid clamps (which also secure the second-to-last module in the row), tightening them as you did in Step 7. 12. Add and tighten the last module’s two end clamps as you did in Steps 2–3. If you’re installing a second row, you must add two row-to-row (R2R) spacers to the upper edge of each of the completed first row’s modules. In addition, before you proceed, read Section 5.6.1 now so that you can allow for the row-to-row (R2R) grounding clip installation (if you chose that grounding method). Note: These instructions assume that any second row you add will be “above” the first row between the peak and the first row). Fig. 24 Fig. 25 Fig. 26 Document #508988 RevH 29 SunPower Proprietary 13. For each of the modules in the first row, fit two R2R spacers in its upper frame edge, one each approximately 20 cm (8) away from each upper frame corner (Fig. 27 and Fig. 28). Note: If you chose to use the R2R grounding clip to achieve row-to-row grounding, it is acceptable to slightly shift the position of the spacer nearest the grounding clip just enough to correctly install the R2R clip—but you must still install two spacers on the module that has the R2R clip. 14. Repeat Steps 1–12 to fully install the second row, allowing the second row’s modules to gently rest evenly on the spacers. Note: The spacers provide no structural support for the modules. Leave the spacers in place after module installation. Fig. 27 Fig. 28 Document #508988 RevH 30 SunPower Proprietary 5.6.1 Install R2R Grounding Clip Note: Refer to Section 5.5. You must enable row-to- row grounding—achieving it through the method described in this section is optional. If you decide to use the row-to-row (R2R) grounding clip, note that it is not applicable for arrays that consist of a single row. If you decide to use the R2R clip you must still connect one ground lug to one of the rails in the first row, and run the copper ground wire to it so that its electrical bond will transfer to the other rows through the R2R clips (refer to Fig. 10). The R2R grounding clip provides a grounding path between rows of modules that are not mounted on the same rail pair. The R2R clip also enforces the same row-to-row module gap that the R2R spacers provide. Note. The entire first row does not have to be fully installed before you begin installing the second row and the R2R grounding clip. 1. The R2R clip has two threaded bosses with bolts built into it. After you have installed the first row, fit the R2R clip (with bolt heads up) onto the frame edge of that row’s first module (the edge that’s adjacent to the modules in the second row; Fig. 29) and let it hang down (Fig. 30). Position the clip 15.3–25.4 cm (6–10”) from the end of the row (Fig. 31). Fig. 29 Fig. 30 Fig. 31 Document #508988 RevH 31 SunPower Proprietary 2. Lift the clip slightly so that it is parallel to the module and then tighten the first-row bolt (the outer one, nearest the module corner) to 9.6 N- m (85 +5/0 in-lb), so that the clip firmly clamps onto the module frame (Fig. 31). 3. Carefully bring the adjacent module of the second row toward the module that has the R2R clip (Fig. 32). 4. Fit the frame edge of the second-row module into the open jaw of the R2R clip (Fig. 33). 5. Secure the second-row module according to Section 5.6. 6. After the second-row module is fully installed, tighten the second-row bolt (the inner bolt) on the R2R clip to as described in Step 2. Fig. 32 Fig. 33 Document #508988 RevH 32 SunPower Proprietary 5.7 Standalone Modules Any module in an array that will not include mid clamps as part of its mounting hardware is considered a “standalone module.” Typically a standalone module arises when an array has a module “missing” in order to accommodate a rooftop feature or obstruction, or when an array forms a “pyramid” shape and the topmost (or bottommost) row contains only a single module. You must ground a standalone module as if it were its own row, and you must do so in one of the following two ways: Attach a ground lug assembly to one of its rails Fig. 34), and route the copper ground wire to it. OR Install another R2R grounding clip (Fig. 35; refer to Section 5.6.1). Fig. 34 Fig. 35 Document #508988 RevH 33 SunPower Proprietary Appendix A: Install Rail-Mounted Junction Box If you decide to use the rail-mounted J-box (RMJ), install it before you install modules. Important! Only glands and fittings that have gaskets and that are suitable for wet locations may be used. 1. Determine the location for the RMJ. You can mount the RMJ “above” or “below” the rail (Fig. A1). Fig. A1 2. According to your wire management strategy, determine, mark, and drill out the necessary entry locations on the sides of RMJ (do not drill the cover). 3. Drill a weep hole (min. 1/8; max. 1/4) in the RMJ at its lowest point. Note: SunPower provides 1/2” cable glands; the maximum conduit size is 1. 4. Install glands or conduit fittings in the RMJ. If you’re using a provided cable gland, torque its locknut to 4.5 N-m 40 +5/0 in-lbs). Important! Do not mount conduit or glands to the box cover. 5. Fit the RMJ lip into the top channel of the rail (Fig. A2), and then tilt the RMJ downward until both of its tabs click around and fully engage the rail (Fig. A3). Document #508988 RevH 34 SunPower Proprietary Fig. A2 Fig. A3 6. Manually squeeze each tab upward to verify full engagement (Fig. A4) Fig. A4 7. Remove the RMJ cover and insert the cable ends. For the provided glands, torque sealing nuts to 7.9 N-m (70 in- lbs). 8. Complete the installation of any conduit and wiring. 9. Fit the cover on the RMJ and use the #2 square-drive screwdriver to torque each of the four cover screws to 1.8 N-m (16 in-lbs). Document #508988 RevH 35 SunPower Proprietary Appendix B: Install Rooftop Transition Flashing Decide on the position of the installed flashing with respect to your array. Install the flashing only at a location that is both between the rafters and within the array perimeter, such that it will be underneath and fully concealed by the array when the array is complete. 1. After you have selected the location for the flashing, position the flashing on the roof as follows: With its ROOF RIDGE arrow toward the peak. Such that its lower alignment marks are positioned at or a maximum 2.5 cm (1) above the bottom edge of the second of the two affected shingle courses at your chosen location (Fig. B1). Such that the left and right edges of the flashing are perpendicular to the shingle courses. Fig. B1 2. Keeping the flashing in position, trace its perimeter onto the shingles, and mark the flashing’s alignment marks on the shingles as well. Document #508988 RevH 36 SunPower Proprietary 3. Remove the flashing and use a straight edge to trace the lines between the alignment marks onto the shingles Fig. B2). Fig. B2 4. Using a roofing bar, gently separate the two courses of affected shingles from underlying layers in the marked region, while leaving the shingles in place. 5. Cut and remove one layer of shingle material in the crosshatched area (Fig. B3 and Fig. B4). Important! DO NOT REMOVE ANY SHINGLE MATERIAL FROM ANY COURSES THAT EXTEND BELOW THE BOTTOM OF THE FLASHING, EVEN IF THAT MATERIAL IS INSIDE THE BOX. DO NOT CUT THROUGH THE ROOF MOISTURE BARRIER EXCEPT FOR THE TRANSITION HOLE INTO THE ATTIC OR BUILDING SPACE. Fig. B3 Document #508988 RevH 37 SunPower Proprietary Fig. B4 6. To test fit, slide the flashing up under the shingle course that will align with the lower edge of the flashing (the middle” course of the three affected courses). If roof nails are in the way, remove them with a roofing bar and seal the remaining holes with appropriate sealant for the particular roof type. 7. Remove the flashing. 8. Through the roof surface from which you removed material, drill a single pass-through hole no larger than 5 cm 2), centered E–W, and no less than 10.2 cm (4) from the lower edge of the flashing (Fig. B5). Important! The bottom point of the hole must be a minimum of 10.2 cm (4) from the bottom edge of the flashing. Fig. B5 Document #508988 RevH 38 SunPower Proprietary 9. The flashing comes with three hole locations each marked with a white dot. Allowing for the size of your chosen gland, drill the flashing with a step drill tip (or knockout tool) centered on one of the dots (Fig. B6). Important! Use only liquid-tight glands with gaskets appropriate for your chosen wire type. Note: Use only the three provided drill locations, and do not drill more holes than necessary. Fig. B6 10. Install and torque the gland and back nut as per the manufacturer guidance (Fig. B7 and Fig. B8). Fig. B7 Fig. B8 Important! UF-B wire is used in this example because it is Listed for exterior and interior use. SunPower recommends that you refer to the applicable NEC edition for your region (some regions adopt editions later than others)—as well as consult with your AHJ—before choosing a wiring strategy. 11. Route and prepare a length of UF-B wire from the service panel entrance to the rooftop. Allow several extra feet for final installation. 12. Insert the cut end of the wire through the roof cutout, leaving sufficient length beyond the roof transition. Document #508988 RevH 39 SunPower Proprietary 13. From the underside of the flashing, thread the UF-B wire through the gland, and then carefully slide the flashing into position (Fig. B9). Fig. B9 Fig. B10 14. Ensuring that you leave enough extra wire length, tighten the gland around the wire per the gland manufacturer specification (Fig. B10). Important! Do not loosen the seal at the base of the gland! 15. Remove the flashing and turn it over, taking care to not disturb the gland. 16. Apply a single 1/2 continuous bead of sealant to the underside of the flashing, approximately 2.5 cm (1) from its perimeter (Fig. B11). Use only 100% silicone roof sealant, such as Henry 884 Tropi-Cool® or equivalent. Ensure that the sealant has not exceeded its shelf life and has not exceeded the recommended maximum time-to-use period after opening, as defined in the manufacturer guidance. Fig. B11 Document #508988 RevH 40 SunPower Proprietary 17. Conforming to the exact outline you made previously, fit the flashing back into position while sliding the excess wire down into the attic space (Fig. B12). Fig. B12 Fig. B13 18. Lift the middle course of shingles and secure the flashing with one sheet metal screw (#9-15 1-1/2”); or nail (#12 ring shank 1-1/4”); on each side of the flashing; 2.5 cm (1”) from the flashing edge. 19. Apply a liberal cap of sealant on the head of each screw (or nail) (Fig. B13). 20. Lift the two courses of shingles and apply a horseshoe-shaped bead of sealant on the top surface of the flashing as you did on the bottom of the flashing in Step 16) (Fig. B14). Fig. B14 Document #508988 RevH 41 SunPower Proprietary 21. Press down firmly on the shingles over the flashing outline to properly bond the assembly to the roof surface. 22. Similar to Step 9, drill the flashing for conduit entry. 23. Install and torque all conduit fittings as per manufacturer guidance. 24. Mount conduit as per your array design. Conduit must be rated for the appropriate exposure. Exterior conduit and fittings must be rated liquid tight, and installed in an appropriate liquid-tight manner, including gaskets on all sealing faces where needed. A coupling can be used to connect interior and exterior raceways through the flashing. For the flashing side of the conduit run, secure the conduit within 30.5 cm (12) of either side (attic side or roof side) of the flashing. Document #508988 RevH 42 SunPower Proprietary Appendix C: DC Rail Clips DC rail clips provide optional additional support for DC conductors. Use them as necessary to help keep all wiring off of the roof surface. The maximum number of wires that each DC rail clip is permitted to carry is three. Space DC clips no more than 61 cm (24) apart. Note: Attaching rail clips is easiest to do before you mount the modules. SunPower recommends that you route DC wires parallel to the rails. In addition, always prevent wires from drooping below the lower edge of the rails. 1. Place the wires (max. three) into the wire channel of the clip (Fig. C1 and Fig. C2), position the clip beneath the rail, and then fit the first lip into the side channel of the rail (Fig. C2). Fig. C1 Fig. C2 Document #508988 RevH 43 SunPower Proprietary Fig. C3 Fig. C4 2. Holding the wires in position within the clip, rotate the clip under and around toward the top of the rail (Fig. C3), gently pushing the second lip over the top of the rail until it snaps into the top channel of the rail (Fig. C4). You should hear the second lip click into the channel. To remove clips, simply press down on the first lip to release it from the rail (Fig. C5). Fig. C5 Fig. C6 You can also use the DC rail clips in the same manner to support wires that route perpendicular to the rail, but extra care must be given to ensure that the wires to not rub on the clip edge or the rail edge. In addition, ensure that you route the wires over the top of the rails (Fig. C6). Document #508988 RevH 44 SunPower Proprietary Appendix D: Module Removal Important! If you have to remove a module from an array, note that leaving any module in the array when it is physically secured only by two end clamps is expressly prohibited. To remove a module from an existing array: 1. Turn off the DC disconnect at the inverter. 2. Using a clamp-on multimeter, verify that current flow has stopped on all DC source circuit conductors. If fuses are installed at the combiner, remove the fuses to isolate the circuit with the target module from parallel- connected sources. 3. Using a clamp-on current meter, test each individual circuit conductor AND each equipment ground conductor on the rooftop before opening any module connectors (before disconnecting any module leads). 4. If the current is zero amps, it is safe to proceed to Step 8. If there is any current present (greater than 0 amps), double-check that the circuit is in fact disconnected from the inverter and proceed to Step 5. 5. If the circuit has been disconnected from the inverter and current is still present, DO NOT INTERRUPT THE CIRCUIT! (Do not unplug any module leads or open any breakers, for example.) It is likely that a short circuit or a ground fault is present—or both. 6. Troubleshoot and correct the short circuit, the ground fault, or both. 7. After verifying that the circuit is disconnected from the inverter and that there are no short circuits or ground faults present, use the clamp-on meter to retest each individual circuit conductor AND each equipment ground conductor. Verify that the current for each is zero before proceeding. 8. Disconnect (unplug) the target module’s two electrical leads from the modules that are adjacent to the target module. 9. Remove the adjacent modules and mid clamps, ideally from the side of the row that contains fewer modules between the target module and the end of the row (Fig. D1 and Fig. D2). If there is any other grounding or wire management hardware present, remove it as well. 10. Remove the target module. If the target module will be out of the array solely for the purposes of replacing it with another module immediately, ensure that you remain aware of the adjacent module’s temporary partial securement, and execute the swap efficiently, reusing all of the mid clamps and end clamps. If the target module will be out of the array for an extended period, carefully attach two mid clamps to the now-exposed edge of each adjacent module (Fig. D1, Fig. D2, and Fig. D3) according to Section 5.6 of this guide (note that two of the teeth on these mid clamps will instead directly engage the top of the rail—this is acceptable for module removal and replacement). The mid clamps will keep the modules bonded to the rail, which is bonded to the equipment grounding conductor (EGC) and in turn the grounding electrode conductor GEC). 11. After replacing or servicing the target module, reassemble the row according to the instructions in this guide. Document #508988 RevH 45 SunPower Proprietary Important! When reinstalling a removed module, shift its original location slightly (min. 1.6 mm [1/16]) relative to its original installed position and in the direction perpendicular to the rail before retightening the mid clamps and end clamps.
