Ward, SE, PE Clint C. Karren, PE Structural Engineering Manager Structural Engineering Manager jon.wardoo vivintso/ar.com clint.karrenC@vivintsolar.com November 21, 2016 Mr. Dan Rock, Project Manager Vivint Solar 1800 W Ashton Blvd. Lehi, UT 84043 Re: Structural Engineering Services Cruz Residence 1 Mansell Pkwy, Salem, MA S-5303506; MA-01 Dear Mr. Rock: Pursuant to your request, we have reviewed the following information regarding solar panel installation on the roof of the above referenced home: 1. Site Visit/Verification Form prepared by a representative from our office under my supervision identifying specific site information including size and spacing of members for the existing roof structure. 2. Design drawings of the proposed system including a site plan, roof plan and connection details for the solar panels. This information was prepared by the Design Group and will be utilized for approval and construction of the proposed system. 3. Photovoltaic Rooftop Solar System Permit Submittal identifying design parameters for the solar system. 4. Photographs of the interior and exterior of the roof system identifying existing structural members and their conditions. 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: Description of Residence: The existing residence is typical wood framing construction with the roof system consisting of the following: • Roof section is composed of 2x8 dimensional lumber at 16" on center and a single layer of roofing. The attic space is unfinished and photos indicate that there was free access to visually inspect the size and condition of the roof members. All wood material utilized for the roof system is assumed to be Spruce-Pine-Fir #2 or better with standard construction components. The existing roofing material consists of composite shingle. Stability Evaluation: A. Wind Uplift Loading 1. Calculations for uplift are based on ASCE/SEI 7-10 Minimum Design Loads for Buildings and other Structures, a wind speed of 100 mph based on Exposure Category B and 24 degree roof slopes on the dwelling areas. Ground snow load is 40 PSF for Exposure B, Zone 2 per (ASCE/SEI 7-10). 2. Total area subject to wind uplift is calculated for the Interior, Edge and Corner Zones of the dwelling. Page f oft vivi t. solar B. Loading Criteria 8 PSF= Dead Load (roofing/framing) 40 PSF=Ground Snow Load 3 PSF= Dead Load (solar panels/mountino hardware) Total Dead Load= 11 PSF The above values are within acceptable limits of recognized industry standards for similar structures and in accordance with the 2009 International Residential Code with Massachusetts Amendments. Analysis performed on the existing roof structure utilizing the above loading criteria indicates that the existing members will support the additional panel loading without damage, if installed correctly. C. Roof Structure Capacity 1. The photographs provided of the attic space and roof rafters show that the framing is in good condition with no visible signs of damage caused by prior overstressing. D. Solar Panel Anchorage 1. The solar panels shall be mounted in accordance with the most recent "Ecolibrium Solar Installation Manual", which can be found on the Ecolibrium Solar website (www.ecolibriumsolar.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. 2. The solar panels are 1 1/2"thick and mounted 4 1/2" 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 is 205 lbs/inch of penetration as identified in the National Design Specifications (NDS) of timber construction specifications for Spruce-Pine-Fir assumed. Based on our evaluation, the pullout value, utilizing a penetration depth of 2 1/2", is less than the maximum allowable per connection and therefore is adequate. 4. Considering the roof slopes, the size, spacing, condition of the roof, the panel supports shall be placed at and attached no greater than every fourth roof member as panels are installed perpendicular across members and no greater than the panel length when installed parallel to the members (portrait). No panel supports spacing shall be greater than four (4) spaces or 64" o/c, whichever is less. 5. Panel support connections shall be staggered to distribute load to adjacent members. Based on the above evaluation, with appropriate panel anchors being utilized the roof system will adequately support the additional loading imposed by the solar panels. This evaluation is in conformance with the 2009 International Residential Code with Massachusetts Amendments, current industry standards and practice, and the information supplied to us at the time of this report. Should you have any questions regarding the above or if you require further information do not hesitate to contact me. 1AA OF Regards, N P G Jon P.
