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: 140 mph(3-sec gust) Wind exposure category:C Ground snow load,Pg:30 psf Flat roof snow load,Pf:25 psf Existing Roof Structure Roof structure:2x4 manufactured trusses @ 24”o.c. Roofing material:composite shingles Roof pitch:6:12 Connection to Roof Mounting connection:(1)5/16"lag screw w/min.2.5"threaded embedment into framing Maximum mounting spacing along rails: Zone 1(Beyond 4'from roof edge or ridge):48"o.c. Zone 2(Within 4'of roof edge parallel or perpendicular to slope):48"o.c. Zone 3(Within 4'of roof eave-eave corner or eave-ridge corner):24"o.c. Install(2)rails per row of panels,evenly spaced;panel length perpendicular to the rails shall not exceed 70 in Rail cantilever shall not exceed 33%of connection spacing Connections shall be staggered so as not to overload any existing structural member 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,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. 651 W.Galena Park Blvd.,Ste. 101/Draper,UT 84020/T(801)990-1775/F(801)990-1776/www.vectorse.com CTORE n Q 1 n E E R s VSE Project Number:U3232.0520.221 Lampson Residence 6/2/2022 The solar array will be flush-mounted(no more than 10"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. Increases in lateral forces less than 10% are considered acceptable. Thus the existing lateral force resisting system 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 must 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.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 panels,solar 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.Vector Structural Engineering shall be notified of any changes from the approved layout prior to installation.
