Based on our evaluation, the pullout demand is less than the maximum allowable per <br /> connection and therefore is adequate. <br /> • EcoFasten Solar: (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. The maximum allowed spacing was calculated for the Wind Speed shown in paragraph B above, using the wind <br /> load uplift procedures of ASCE 7-10 and is specified below. These spacing requirements apply to all mount <br /> types indicated above. The following values have been verified by in-house testing and the mounting hardware <br /> manufacturers'data, which are available upon request. Panel support connections should be staggered,where <br /> possible,to 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 566 451 417 566 451 417 <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 /> \\\1111 I I I///,/ <br /> P��HE W�//// . <br /> Regards, <br /> J.
