VSE Project Number:U1878-2181-181 Mattison Residence . ' '');;;HV E C T C:1 R. 10/19/2018 E n s I n E ER S The solar array will be flush-mounted (no more than 6" above the roof surface) and parallel to the roof surface. Thus, we conclude that any additional wind loading on the structure related to the addition 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. Regarding seismic loads, we conclude that any additional forces will be small. With an assumed roof dead load of 10 psf,solar array dead load of 3 psf, and affected roof area of 33%(maximum), the additional dead load (and consequential seismic load)will be 9.4%.This calculation conservatively neglects wall weight.Because the increase in lateral forces is less than 10%, this addition meets the requirements of the exception in Section 807.5 of the 2015 IEBC as referenced in 780 CMR Chapter 34,9th Edition.Thus the existing structure is permitted to remain unaltered. Limitations Installation of the solar panels must be performed in accordance with manufacturer recommendations. All work performed must be in accordance with accepted industry-wide methods and applicable safety standards. The contractor shall notify Vector Structural Engineering,LLC should any damage, deterioration or discrepancies between the as-built condition of the structure and the condition described in this letter be found.Connections to existing roof framing must be staggered,except at array ends, so as not to overload any existing structural member. The use of solar panel support span tables provided by others is allowed only where the building type,site conditions,site-specific design parameters,and solar panel configuration match the description of the span tables.The design of the solar panel racking(mounts,rails,etc.),and electrical engineering is the responsibility of others. Waterproofing around the roof penetrations is the responsibility of others. Vector Structural Engineering assumes no responsibility for improper installation of the solar array.

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 3' — Code:Massachusetts State Residential Code(780 CMR Chapter 51,9th Edition(2015 IRC)) Risk Category:II Design wind speed: 140 mph (3-sec gust)per ASCE 7-10 Wind exposure category:C Ground snow load: 30 psf Existing Roof Structure Roof structure:2x8 rafters @ 16"O.C. Roofing material:composite shingles Connection to Roof Mounting connection:(1)5/16" lag screw w/min.2.5"embedment into framing at max.48"O.C.along rails 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 ASCE 7,resulting in reduced design snow load on the panels. The gravity loads in the area of the solar array are decreased; thus, the stresses of the structural elements are decreased. Therefore, the requirements of Section 807.4 of the 2015 1EBC as referenced in 780 CMR Chapter 34, 9th Edition are met and the structure is permitted to remain unaltered. 651 W.Galena Park Blvd.,Ste.101/Draper,UT 84020/T(801)990-1775/F(801)990-1776/www.vectorse.com ' . • • g7"ite $Co4n/monevectit4 olagArzmackael4 '31 Office of Consumer Affairs and Business Regulation 10 Park Plaza- Suite 5170 e, Boston, MassacOusetts 02116 Home Improvement-Contractor Registration Erlari-LiT3LiEcCES3 itt;illtS171 Type: Corporation frth Registration: 174170 NEW ENGLAND CLEAN ENERGY t ..q:) rsE-13 Eviration: 01/01/2019 " " S•a 43 Broad Street 1;1 :11-•vni :::3 I tl Suite A408 Hudson, MA 01749 Earl rid Update Address and return card.
