Wyssling, PE Head of Structural Engineering scott.wyssling@vivintsolar.com December 4, 2014 Mr. Dan Rock, Project Manager Vivint Solar 24 Normac Road Woburn MA 01801 Re: Structural Engineering Services Lewis Residence 34 Outlook Avenue, Salem MA S-4076498 2.805 kW System 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 Vivint Solar representative identifying specific site information including size and spacing of rafters 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 2 x 6 dimensional lumber at 16" on center with 1 x 8 collar ties every 48". The attic space is unfinished and photos indicate that there was free access to visually inspect the size and condition of the roof rafters. All wood material utilized for the roof system is assumed to be Spruce-Pine-Fir #2 or better with standard construction components. Our review of the photos of the exterior roof does not indicate any signs of settlement or misalignment caused by overstressed underlying members. Stability Evaluation: A. Wind Uplift Loading 1. Refer to attached Ecolibrium Solar calculations sheet for ASCE/SEI 7-10 Minimum Design Loads for Buildings and other Structures, 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. vivi t. C' Page 2 of 2 B. Loading Criteria • 10 PSF= Dead Load roofing/framing 40 PSF=Live Load (ground snow load) • 5 PSF= Dead Load solar panels/mounting hardware Total Dead Load=15 PSF The above values are within acceptable limits of recognized industry standards for similar structures. Analysis performed of the existing roof structure utilizing the above loading criteria indicates that the existing rafters 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 "Ecofibrium Solar Installation Manual', which can be found on the Ecolibrium Solar website (ecolibriumsolar.com). It during solar panel installation, the roof framing members appear unstable, deteriorated, structurally compromised or deflect non-uniformly, our office should be notified before proceeding with the installation. 2. Maximum allowable pullout per lag screw is 235 Ibs/inch of penetration as identified in the National Design Standards (NDS) of timber construction specifications for Hem-Fir (North Lumber) assumed. Based on our evaluation, the pullout value, utilizing a penetration depth of 2 Yi', is less than what is allowable per connection and therefore is adequate. Based on the variable factors for the existing roof framing and installation tolerances, using a thread depth of 2 1/2' with a minimum size of 5/16" lag screw per attachment point for panel anchor mounts should be adequate with a sufficient factor of safety. 3. Considering the roof slopes, the size, spacing, condition of roof, the panel supports shall be placed at and attached to no greater than every fourth roof rafter as panels are installed perpendicular across rafters and no greater than the panel length when installed parallel to the rafters (portrait). No panel supports spacing shall be greater than four (4) rafter spaces or 64"o/c, whichever is less. 4. Panel supports connections shall be staggered to distribute load to adjacent rafters. Based on the above evaluation, it is the opinion of this office that with appropriate panel anchors being utilized the roof system will adequately support the additional loading imposed by the solar panels. This evaluation is based on information supplied to us at the time of this report and current industry standards and practices.
