Elvestad, PE swyssling@wysslingconsulting.com August 27, 2025 Ambia Energy 335 South 560 West, Suite 100 Lindon, Utah 84042 Re: Engineering Services Iverson Residence 501 37th Street, Anacortes WA 10.935 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: Built in place wood trusses at 16” on center. All truss members are constructed of 2x4 dimensional lumber. Roof Framing: Assumed 2x6 dimensional lumber at 24” on center. Roof Material: Metal roofing and membrane roofing Roof Slope: 6 and 25 degrees Attic Access: Accessible/Inaccessible 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 psf o New Solar Panels and Racking = 3 psf o TOTAL = 10 psf • Live Load = 20 psf (reducible) – 0 psf at locations of solar panels • Ground Snow Load = 20 psf • Wind Load based on ASCE 7-16 o Ultimate Wind Speed = 98 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 2018 Washington State Residential Code. 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 Pegasus Solar 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 system utilizes the Pegasus SkipRail racking system. Please reference the stamped plan set for rail and mounting locations. 3. The maximum allowable withdrawal force for a 5/16” lag screw is 229 lbs per inch of penetration as identified in the National Design Standards (NDS) of timber construction specifications. Based on a minimum penetration depth of 2½”, 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 one 5/16” diameter lag screw with a minimum of 2½” embedment will be adequate and will include a sufficient factor of safety. 4. 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. E. Solar Panel Anchorage 1. The solar panels shall be mounted in accordance with the most recent “Sunmodo 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. System will be attached to the metal roofing material utilizing the patented Sunmodo connection. Installation of the connections shall be in accordance with the manufacturer’s recommendations. 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 2018 Washington State Residential Code, current industry standards, and is based on information supplied to us at the time of this report.
