6 Garfield - Revised Plans - to include fire setbacks 76 North Meadowbrook Drive Scott E. Wyssling, PE Alpine, UT 84004 Coleman D. Larsen, SE, PE office (201) 874-3483 Gregory T. Elvestad, PE swyssling@wysslingconsulting.com May 10, 2023 Revised May 31, 2023 Posigen Solar 280 Moody Street Ludlow, MA 01056 Re: Engineering Services Serrano Residence 6 Garfield Avenue, Florence MA 10.400 kW System To Whom It May Concern: We have received information regarding solar panel installation on the roof of the above referenced structure. Our evaluation of the structure is to verify the existing capacity of the roof system and its ability to support the additional loads imposed by the proposed solar system. A. Site Assessment Information 1. Site visit documentation identifying attic information including size and spacing of framing 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 will be utilized for approval and construction of the proposed system. B. Description of Structure: Roof Framing: Prefabricated wood trusses at 24” on center. All truss members are constructed of 2 x 4 dimensional lumber. Roof Material: Composite Asphalt Shingles Roof Slope: 30 degrees Attic Access: Accessible Foundation: Permanent C. Loading Criteria Used • Dead Load o Existing Roofing and framing = 7 psf o New Solar Panels and Racking = 3 psf o TOTAL = 10 PSF • Dead Load o Existing Roofing and framing = 7 sf o New Solar Panels and Racking = 3 f o TOTAL = 10 • Live Load = 20 psf (reducible) – 0 psf at locations of solar panels • Ground Snow Load = 40 psf • Wind Load based on ASCE 7-10 o Ultimate Wind Speed = 117 mph (based on Risk Category II) o Exposure Category C Analysis performed of the existing roof structure utilizing the above loading criteria is in accordance with the 2015 International Residential Code, including provisions allowing existing structures to not require strengthening if the new loads do not exceed existing design loads by 105% for gravity elements and 110% for seismic elements. This analysis indicates that the existing framing will support the additional panel loading without damage, if installed correctly. Page 2 of 2 D. Solar Panel Anchorage 1. The solar panels shall be mounted in accordance with the most recent Ecofasten installation manual. 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 maximum allowable withdrawal force for a #12 lag screw is 176 lbs per inch of penetration as identified in the National Design Standards (NDS) of timber construction specifications. Based on two screws with a minimum penetration depth of 2 ½ ”, the allowable capacity per connection is greater than the design withdrawal force (demand). Considering the variable factors for the existing roof framing and installation tolerances, the connection using two #12 lag screws with a minimum of 2 ½ ” embedment will be adequate and will include a sufficient factor of safety. 3. Considering the wind speed, roof slopes, size and spacing of framing members, and condition of the roof, the panel supports shall be placed no greater than 48” on center. Based on the above evaluation, this office certifies that with the racking and mounting specified, the existing roof system will adequately support the additional loading imposed by the solar system. This evaluation is in conformance with the 2015 IRC, current industry standards, and is based on 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. Very truly yours, Scott E.
