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: Assumed prefabricated wood trusses at 24” on center. All truss members are constructed of 2x4 dimensional lumber. Roof Material: Concrete Tile & Composite Asphalt Shingles Roof Slope: 20 degrees Attic Access: Inaccessible Foundation: Permanent C.Loading Criteria Used •Dead Load o Existing Roofing and framing = 13 psf o New Solar Panels and Racking = 3 psf o TOTAL = 16 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 = 0 psf •Wind Load based on ASCE 7-16 o Ultimate Wind Speed = 95 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 2022 California Building 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. 2307 N Towner St - 2017896310/18/2023 Page 2 of 2 D.Solar Panel Anchorage 1.Concrete Tile i.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. ii.The maximum allowable withdrawal force for a 5/16” lag screw is 229 lbs per inch of penetration as identified in the National D esign Standards (NDS) of timber construction specifications. Based on two screws with 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 two 5/16” diameter lag screw with a minimum of 2½” embedment will be adequate and will include a sufficient factor of safety. iii.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 centers. 2.Composite Asphalt Shingles i.The solar panels shall be mounted in accordance with the most recent Unirac 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. ii.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. iii.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 2022 California Building Code, current industry standards, and is based on information supplied to us at the time of this report.

Elvestad, PE swyssling@wysslingconsulting.com July 1, 2024 Exo Energy 1358 La Miranda Drive San Marcos, CA 92071 Re: Engineering Services Vandervoort Residence 2307 N Towner Street, Santa Ana, CA 7.200 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: Assumed prefabricated wood trusses at 24” on center. All truss members are constructed of 2x4 dimensional lumber. Roof Material: Tile Roofing Roof Slope: 20 degrees Attic Access: Inaccessible Foundation: Permanent C. Loading Criteria Used • Dead Load o Existing Roofing and framing = 13 psf o New Solar Panels and Racking = 3 psf o TOTAL = 16 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 = 0 psf • Wind Load based on ASCE 7-16 o Ultimate Wind Speed = 95 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 2022 California Building 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. 2307 N Towner St 8/23/2024 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 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 two screws with a minimum penetration depth of 2-1/2”, 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 5/16” diameter lag screws with a minimum of 2-1/2” 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 2022 California Building Code, current industry standards, and is based on information supplied to us at the time of this report.
