B Greenfield, MA 01301 REFERENCE: Moran - Northampton Residence: 8 Warner Street, Northampton, MA 01062 PV Squared Project: MOFL23092022R Solar Array Installation To Whom It May Concern: We have reviewed the existing structure at the above referenced site.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: 2x10 rafters @ 16" o.c. Roof slope: 36° Conclusions Based upon our review,we conclude that the existing structure is adequate to support the proposed solar panel installation. See attached calculations. 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. Increases in lateral forces less than 10%are considered acceptable.Thus the existing lateral force resisting system is permitted to remain unaltered. 651 W.
