Page 2 of 2 <br /> B. Solar Panel Anchorage <br /> 1. The solar panels shall be mounted in accordance with the most recent"Everest Installation Manual", which <br /> can be found on the Everest website (https:Heverest-solarsystems.com/). If during solar panel installation, <br /> the roof framing members appear unstable or deflect non-uniformly, our office should be notified before <br /> proceeding with the installation. <br /> 2. Maximum allowable pullout per lag screw is 235 Ibs/inch of penetration as identified in the National Design <br /> Standards (NDS) of timber construction specifications for Doug-Fir #2 assumed. Based on our evaluation, <br /> the pullout value, utilizing a penetration depth of 2 1/z", is less than what is allowable per connection and <br /> therefore is adequate. Based on the variable factors for the existing roof framing and installation tolerances, <br /> using a thread depth of 2 V with a minimum size of 5/16" lag screw per attachment point for panel anchor <br /> mounts should be adequate with a sufficient factor of safety. <br /> 3. Considering the roof slopes, the size, spacing, 'condition of roof, the panel supports shall be placed no <br /> greater than 48"o/c. <br /> 4. Panel supports connections shall be staggered to distribute load to adjacent Rafters. <br /> Based on the above evaluation, it is the opinion of this office that with appropriate panel anchors being utilized the roof <br /> system will adequately support the additional loading imposed by the solar panels. This evaluation is in conformance <br /> with the FBC 2017,current industry and standards,and based on information supplied to us at the time of this report. <br /> Should you have any questions regarding the above or if you require further information do not hesitate to contact me. <br /> AVVetruly yours, <br /> V.Wysslin <br /> Florida License o. 8 <br /> nos PLAN HAS BEEN ELEOTROMCALLY SGNMAND ,,�,11�11111111f 1/J���� <br /> S&LLm BY SCO7T WYSSUNG,PE USIIIG A DIGITAL <br /> SIGNATURE AND DATE PLRV1 D CORES GF THIS \\ t G• V S� //// <br /> DOCULVITARE NOT CONSIDERED SGNM AND <br /> EA \\._,� _...• / + <br /> SLED AND THE SIGNATURE MUST BE VERFIED �� ' // <br /> ON AINY ELECTRONIC CORES ` ••�y1 _ / <br /> ` 8 <br /> r TATE OF <br /> �/�owe ' •. ..•.• . , ,� <br /> ////���11Jr1,1 JI1111►�\,1\1, <br /> CONSULTING <br />
