The purpose of our review was to determine the adequacy of the existing structure to support the proposed installation of solar panels on the roof as shown on the panel layout plan. Based upon our review,we conclude that the existing structure is adequate to support the proposed solar panel installation. Design Parameters Code:Massachusetts State Residential Code(780 CMR Chapter 51,9th Edition(2015 IRC)) Risk Category: II Design wind speed,Vult: 117 mph(3-sec gust) Wind exposure category:C Ground snow load,Pg:40 psf Flat roof snow load,Pf: 35 psf Existing Roof Structure Roof structure:2x8 rafters @ 24"o.c. Roof slope:22°&45° Conclusions Based upon our review, we conclude that the existing structure is adequate to support the proposed solar panel installation. The glass surface of the solar panels allows for a lower slope factor per ASE 7, resulting in reduced design snow load on the panels. The gravity loads, and thus the stresses of the structural elements, in the area of the solar array are either decreased or increased by no more than 5%.Therefore,the requirements of Section 807.4 of the 2015 IEBC as referenced in 780 CMR Chapter 34,9th Edition are met and the structure is permitted to remain unaltered. The solar array will be flush-mounted (no more than 10" above the roof surfce) and parallel to the roof surface. Thus, we conclude that any additional wind loading on the structure related to the ad Lion of the proposed solar array is negligible. The attached calculations verify the capacity of the connections of the solar array to the existing roof against wind (uplift), the governing load case. Increases in lateral forces less than 10% are considered acceptable. Thus the existing lateral force resisting system is permitted to remain unaltered. 651 W.Galena Park Blvd.,Ste. 101/Draper, UT 84020/T(801)990-177 /F(801)990-1776/www.vectorse.com VSE Project Number: U1898.0154.231 VECT Bourne Residence a R 3/17/2023 E 1'l Q 1 f"-1 � E F2 S Limitations Installation of the solar panels must be performed in accordance with manufacturer recommendations.
