Page 2of2 <br /> D. Solar Panel Anchorage <br /> 1. 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 /> • EcoFasten Solar Installation Manual, which can be found on the EcoFasten Solar website <br /> (www.ecofastensolar.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 required <br /> penetration depth. Based on our evaluation,' the pullout demand is less than the maximum allowable per <br /> connection and therefore is adequate. <br /> • EcoFasten with Rock-It: (1) 5/16" lag screw. Pullout capacity based on National Design Specifications <br /> (NDS)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 48 48 48 <br /> Max Uplift Load Ibs 560 448 415 332 266 246 <br /> E.Summary <br /> Based on the above evaluation,with the structural repairs completed as prescribed and appropriate panel anchors <br /> being utilized,the roof system designed on will adequately support the existing system and the additional loading <br /> imposed by the solar panels, if installed correctly. This evaluation has been performed for the structural elements <br /> only and verifies that they are in conformance with the 2017 Florida Building Code -Residential 6th Edition, current <br /> industry standards and practice, and the information supplied to us 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, ���� '�'�HEw <br /> J.
