A Series Module + Pegasus Composite Shingle Attachment 5. A Series Module + Pegasus Gen1 Tile Attachment 6. A Series Module + Pegasus Gen2 Tile Attachment Loads on the system were calculated in accordance with ASCE 7-16, using the following parameters: • Risk Category II • System weight (including PV modules and rails) = 2.50 psf • Module orientations: Portrait & Landscape • No live load acts on top of the PV modules • Wind speed & exposure as indicated in the tables • Roof height and slope as indicated in the tables • Gable and Hip roofs only with modules not in the overhang sections of the roof • For wind load, topographic factor Kzt = 1.0, and directionality factor Kd = 0.85 per ASCE 7-16 Table 26.6-1 • Wind load coefficients per either wind tunnel testing or ASCE 7-16 Chapter 30 (see notes below tables) • Ground snow load as indicated in the tables • For snow loads, thermal factor Ct = 1.2 (“unheated and open air structures”), per ASCE 7-16 Table 7.3-2 • For snow loads, exposure factor Ce = 0.9 (“fully exposed”), per ASCE 7-16 Table 7.3-1 • For snow loads, slope factor Cs is determined per ASCE 7-16 Figure 7-2 assuming the array is an “unobstructed slippery surface” where snow is free to slide off the array • Seismic short-term spectral acceleration (Ss) = 3.73g, maximum, and seismic site class = D, per ASCE 7-16 Section 11.4.2 • Seismic component importance factor Ip = 1.0 per ASCE 7-16 Section 13.1.3; seismic component response factor Rp = 1.5, and component amplification factor ap = 1.0, per ASCE 7-16 Table 13.5-1 and 13.6-1; seismic loads are calculated per ASCE 7-16 Chapters 11 and 13 • Load combinations per CBC Section 1605.2 Document #524734 Rev D, Vol. 2 2 SunPower Proprietary The maximum allowable spans shown in the tables are based on the calculated loads and the capacity of the rail and the attachment, determined by analysis and testing in accordance with CBC 2019 and referenced standards. • Bending strength of aluminum rails is calculated according to the Aluminum Design Manual 2015 Section B.3.2.1 (LRFD) • The strength of the roof attachment hardware is based on product information from the attachment manufacturer • The strength of the lag screw in withdrawal and shear is calculated according to the National Design Specification (NDS) for Wood Construction, 2018 • The maximum allowable attachment spacing is calculated by checking the demand/capacity ratios for bending in the rail and tension, compression and shear on attachments for all required load combinations. The reported maximum allowable spacing is the greatest spacing, rounded down to the nearest rafter spacing increment, for which the demand/capacity ratios are less than or equal to 1.0. • These tables do not consider the strength of the supporting roof structure. In areas of low snow load, the weight of the array is often considered to offset the design live load of the roof, since personnel and equipment cannot be placed on top of the array. It is recommended to stagger attachment points, as shown in Figure 1, to evenly distribute loads to the rafters. Figure 1 • These tables assume that each module is installed centered over a pair of rails, as shown in Figure 2(a). In cases where one rail is closer to the midpoint of the module, as shown in Figure 2(b), adjustments to the spacing may be required.

Respectfully, Rick Gentry V.P. of Sales & Marketing Page 1 of 8 July 25, 2012 Mr. Rick Gentry Project Number 112448C QUICKSCREWS INTERNATIONAL 5830 Las Positas Road Livermore, CA 94551 Subject: Spanish Tile Roof Hook (Part #STRH90) Laboratory Load Testing Dear Mr. Gentry: As requested, Applied Materials & Engineering, Inc. (AME) has completed load-testing Spanish tile roof hook (see Appendix A, Figure 1). The purpose of our testing was to evaluate the tensile and compressive load capacity of the Spanish tile roof hook attached to a 2"x4" Douglas Fir rafter using #12 Quickscrew (5/16"Øx 3" L T17 302 SS). SAMPLE DESCRIPTION Mockup samples were delivered to our laboratory on July 6, 2012. Mockup configuration consisted of three 16" long rafters at 7"o.c., screwed to 1/2" OSB sheathing. The Spanish tile roof hook is attached through the OSB into the rafter with two fasteners. TEST PROCEDURES & RESULTS 1. Compressive Load Test A total of three tests were conducted for compressive load capacity on July 14, 2012 using a United Universal testing machine. Samples were rigidly attached to the testing machine and a compressive load was applied to the hook. The samples were loaded in compression at a constant rate of axial deformation of 0.09 in. /min. without shock until the bracket was in contact with the OSB sheathing; maximum deflection at maximum load was recorded. Detailed results are provided in Table I. Test setup and typical bracket bending at maximum load are provided in Appendix A. Based on the above testing, the average maximum compression load of the Spanish tile roof hook attached to a 2"x4" Douglas Fir rafter using #12 Quickscrew was determined to be 230 lbf. 2. Tensile Load Test A total of three tests were conducted for tensile load capacity on July 14, 2012 using a United Universal testing machine. Samples were rigidly attached to the testing machine and a tensile load was applied to the hook. The samples were loaded in tension at a constant rate of axial deformation of 0.09 in. /min. without shock until the bracket was bent and the bolt began to pull-out; maximum deflection at maximum load was recorded. Detailed results are provided in Table II.
