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. Deshm Parameters Code:Massachusetts State Building Code(780 CMR Chapter 16,9th Edition(2015 IBC)) Risk Category:11 Design wind speed: 117 mph (3-sec gust)per ASCE 740 Wind exposure category:C Ground snow load: 40 psf Existina Roof Structure Roofslructure:2.8 rafters @ 16"O.C. Roofing material:asphalt shingles Roof slope:9° Connection to Roof Mounting connection:(1)5/16"lag screw w/min.2.5"embedment into framing at max.72" O.C.along rails Conclusions Based upon our review, we conclude that the existing structure is adequate to support the proposed solar panel installation. 1.the mea of the solar array, other live loads will not be present or will be greatly reduced(Massachusetts State Building Code(780 CMR Chapter 16,9th Edition(2015 BC)),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 referenced in 780 CMR Chapter 34,9th Edition are met and the structure is permitted to remain unaltered. 651 W.Galena Park Blvd.,5te. 101/Draper, UT 84020/T(801)990-1775/F(801)990-1776/wvnv.vectorse.com VSE Project Number: U1982-0766-181 E C T O R Jennifer Macdonald Residence 7,2s/zols E n 0 1 n E E R 9 The solar army 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. 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 Stmctuml 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 firaming 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 Stmctural Engineering assumes no responsibility for improper installation of the solar array.
