Matthew Walsh, SE, PE Jon P. Ward, SE, PE Senior Structural Fngineering Manager Structural Engineering Manager James,walshC3 vlvintsolar.com Jon.ward@v/vintsolar.com April 26. 2018 E C E 9 V IE Fie: Structural Engineering Services MAY 17 2018 Wilson Residence 15 Farmington PI, Queensbury, NY TOWN OF QUEENSBURY 5-5890324; NY-04 BUILDING & CODES To Whom It May Concern: We have reviewed the following information regarding solar panel installation on the roof of the above referenced home: 1. Site Visit by a representative from our office under my supervision identifying specific interior and exterior site information including the condition of the existing roof system and the size, spacing, and condition of existing structural framing members. Information gathered during the site visit includes photographs. sketches. and verification forms. 2. Design drawings of the proposed PV System layout, including details to mount the new solar panels to the existing roof. Based on the above information, we have evaluated the structural capacity of the existing roof system to support the additional loads imposed by the solar panels and have the following comments related to our review and evaluation: A. Description of Residence: The existing residence is typical wood framing construction with a maximum of two layers of composite shingle roofing. All wood material utilized for the roof system is assumed to be Hem-Fir(North) #2 or better with standard construction components and consists of the following: • Roof Sections: Prefabricated trusses at 24" on center. Survey photos indicate that there was free access to visually inspect the size and condition of the roof members. • Roof Sections: Dimensional lumber-assumed 2x6 at 16"on center with interior wall supports 7'from the ridge. Survey photos indicate that there was not free access to visually inspect the size and condition of the roof members. B. Loading Criteria 11.13 PSF= Dead Load (roofing/framing) 2.59 PSF = Dead Load (solar panels/mounting hardware) 13.72 PSF=Total Dead Load 20 PSF = Roof Live Load 60 PSF = Ground Snow Load (based on local requirements) Wind speed of 130 mph (based on Exposure Category B -the total area subject to wind uplift is calculated for the Interior, Edge, and Corner Zones of the dwelling.) C. Solar Panel Anchorage 1. The solar panels shall be mounted in accordance with the most recent "Unirac. Inc. Installation Manual", which can be found on the Unirac, Inc. website (www.unirac.com). If during solar panel installation, the roof framing members appear unstable or deflect non-uniformly, our office should be notified before proceeding with the installation. Page,of vivint+ Page 2 of 2 2. The solar panels are 1'/i' thick and mounted 4F/z' off the roof for a total height off the existing roof of 6". At no time will the panels be mounted 'higher than 6"above the existing plane of the roof. 3. Maximum allowable pullout per lag screw(5/16" x 41/2") is 235 lbs/inch of penetration as identified in the National Design Specifications (NDS) of timber construction specifications for Hem-Fir(North). Based on our evaluation, the pullout value, utilizing a penetration depth of 2'/2", is less than the maximum allowable per connection and therefore is adequate. 4. The maximum allowed spacing was calculated for the Wind Speed shown in paragraph B above, using the wind load uplift procedures of ASCE 7-10 and is specified below. The following values have been verified by in- house testing and the mounting hardware manufacturers' data, which are available upon request. Panel support connections shall be staggered to distribute load to adjacent members. Modules in Landscape Modules in Portrait Roof Zone Interior Ede Corner Interior Ede Corner Max Vertical Spacing in 40 40 40 66 66 66 Max Horizontal Spacing in 48 48 48 48 48 48 Max Uplift Load lbs 174 113 63 293 191 107 D. Summary Based on the above evaluation,with appropriate panel anchors being utilized the roof system designed on will adequately support the additional loading imposed by the solar panels, if installed correctly. This evaluation is in conformance with the 2017 New York State Uniform Code Supplement, the 2015 IRC, the 2015 IBC, current industry standards and practice, and the information supplied to us at the time of this report. If there are any questions regarding the above.. or if more information is required, please contact me. F NEW r0 Regards. Jon P.
