Page 2 of 2 <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 332 213 119 560 360 201 <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, \\\\\llI l II///// <br /> V1 e w w,q///�i <br /> J.
