Deflection and stresses of the structural components remain within the allowable for the existing roof. Compliance Method is through an Engineered Design in accordance with the 2017 NY Uniform Building Code Supplement, 2015 IRC and Risk Category 1 for Wind Pressures from 105 mph, 3-sec. gust, Exposure B, and a Ground Snow Load of 50 psf.Mounting locations and methods are as indicated in our plan submission. From the site inspection and analyses and as evidenced by previous roof loads withstood, the existing structure is certified to be structurally adequate to support the reactions of the solar panels in addition to the original design loading. Also the wind analysis concluded that the existing structure is adequate to support the uplift pressures and strengthening or stiffening of the roof framing is not required. The dead-load of the solar panel assembly in this assessment is approximately 3.0 psf. Taking into consideration the risk to building and land, it is my professional opinion, with a reasonable degree of engineering certainty and probability, that the structural integrity of the roof framing will remain sound with the solar panel installation.

Datasheet SUMP WER SUN P WER® Invisimount Span Tables Engineering Summary Letter The following tables list the allowable spacing of attachment points for the SunPower Invisimount mounting system. Loads on the system were calculated in accordance with ASCE 7-10, using the following parameters: • Risk Category II • System weight(including PV modules, rails, attachments, and wiring) = 2.84 psf • 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 • For wind load,topographic factor Kzt= 1.0, and directionality factor Kd =0.85 per ASCE 7-10 Table 26.6-1 • Wind load coefficients per either wind tunnel testing or ASCE 7-10 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 7-10 Table 7-3 • For snow loads,exposure factor Ce=0.9("fully exposed"), per ASCE 7-10 Table 7-2 • For snow loads, slope factor Cs is determined per ASCE 7-10 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) = 3.0g, maximum, and seismic site class= D, per ASCE 7-10 Section 11.4.2 • Seismic component importance factor Ip= 1.0 per ASCE 7-10 Section 13.1.3; seismic component response factor Rp= 1.5, and component amplification factor ap= 1.0, per ASCE 7-10 Table 13.5-1 and 13.6-1; seismic loads are calculated per ASCE 7-10 Chapters 11 and 13 • Load combinations per ASCE 7-10 Chapter 2 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 IBC 2012/2015 and referenced standards. • Bending strength of aluminum rails is calculated according to the Aluminum Design Manual 2010 Section B.3.2.1 (LRFD) * The strength of attachments to the L foot 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, 2010 • 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 2-foot 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 SUN P WER® 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. RAFTER,TYp MODULE,TYP. RAIL,TYP. ATTACHMENT,TYP..
