Installation shall proceed in accordance with the applicable guidelines and recommendations indicated below. <br /> If, during solar panel installation, the roof framing members appear unstable or deflect non-uniformly, our office <br /> should be notified before proceeding with the installation. <br /> • SnapNrack Installation Manual,which can be found on the SnapNrack website(https:Hsnapnrack.com). <br /> 2. The solar panels are 1'/2" thick. At no time will the panels be mounted higher than 10" above the existing <br /> surface of the roof. <br /> 3. The following mounting types shall be used. Please refer to the mounting details for the associated mounting <br /> method requirements. Based on our evaluation, the uplift demand is less than the maximum allowable per <br /> mount and therefore is adequate. <br /> • RL-U SpeedSeal: (1) 5/16" lag screw. Pullout capacity based on National Design Specifications (NDS) <br /> of timber construction specifications for Southern Pine is 235 Ibs/inch penetration. <br /> 4. Fasteners are installed to meet industry standards and this document satisfies requirements in 2017 FBC <br /> 2303.4.5 verifying that the fasteners will not adversely affect the roof framing. <br /> 5. The maximum allowed spacing was calculated for the Wind Speed shown in paragraph B above, using the <br /> wind load uplift procedures of ASCE 7-10. These spacing requirements apply to all mount types indicated <br /> above. The following values have been verified by in-house testing and the mounting hardware manufacturers' <br /> data, which are available upon request. Panel support connections should be staggered, where possible, to <br /> distribute load to adjacent members. <br /> Modules in Landscape Modules in Portrait <br /> Roof Zone Interior Ede Corner Interior Ede Corner <br /> Max Vertical Spacing in 40 40 40 66 66 66 <br /> Max Horizontal Spacing in 48 48 48 33 31 34 <br /> Cantilever in 16 16 16 11 10 11 <br /> D. Summary <br /> Based on the above evaluation, with appropriate panel anchors being utilized, the roof system designed on will <br /> adequately support the additional loading imposed by the solar panels, if installed correctly. This evaluation has <br /> been performed for the structural elements only and verifies that they are in conformance with the 2017 Florida <br /> Building Code-Residential 6th Edition, current industry standards and practice, and the information supplied to us <br /> at the time of this report. <br /> If there are any questions regarding the above, or if more information is required, please contact me. <br /> Regards, ��� '4� - <br /> J.
