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:New York State Uniform Code,2017 Edition(2015 IBC) Risk Category:II Design wind speed: 115 mph (3-sec gust)per ASCE 7-10 Wind exposure category:C Ground snow load: 50 psf Existing Roof Structure Roof structure:2x6 manufactured trusses @ 24"O.C.(timber grade:SPF#2) Roofing material:composite shingles Roof slope: 18° Connection to Roof Mounting connection:(1)5/16"lag screw w/min.4.5"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. In the area of the solar array,other live loads will not be present or will be greatly reduced(New York State Uniform Code, 2017 Edition(2015 IBC), Section 1607.12.5). The member forces in the area of the solar panels are not increased by more than 5%; thus, the stresses of the structural elements are not increased by more than 5%. Therefore, the requirements of Section 807.4 of the 2015 IEBC as adopted by the 2017 NYSUC 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 VSE Project Number:U1886-1651-191 Leonelli Residence 5/8/2019 Residence 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. 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 adopted by the 2017 NYSUC. 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 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.
