GODWIN ENGINEERING AND DESIGN, LLC <br /> 8378 Foxtail Loop, Pensacola, FL 32526 1 (850)712-4219 1 chadogodwineng.com <br /> February 18, 2021 <br /> To: Zephyrhills Building Department <br /> 5335 811,St. <br /> Zephyrhills, FL 33542 <br /> Re: Alvarez— Residential PV Roof Mount Installation <br /> 39435 8th Ave. <br /> Zephyrhills, FL 33542 <br /> Plan Reviewer, <br /> This letter is regarding the installation of a new roof mounted Solar PV System on the existing <br /> residential structure at the address above. I have reviewed the attachment plan and have <br /> determined that the roof mounted PV system is in compliance with the applicable sections of the <br /> following Codes as amended and adopted by the jurisdiction: <br /> 2020 Florida Building Code 7th Edition, FBC <br /> ASCE 7 Min. Design Loads for Buildings&Other Structures <br /> Per 2020 FBC,the Roof Mounted PV system will be subject to the following design criteria: <br /> Design Wind Speed(V it) - 140mph 3sec gust, Exposure Category—B <br /> The PV System consist of the modules, railing, and connection hardware.The system will add a <br /> dead load of approximately 3 psf to the roof. <br /> The existing roof covering is Asphalt Shingle with min.l/z" plywood decking and 2"x 4" roof trusses <br /> 24" O.C. The roofing, decking,and roof trusses are in good condition.The existing structure will be <br /> adequate for supporting the additional PV dead load and wind loads. <br /> The securement method of the PV system is to be flush mounted to the asphalt shingle roof with the <br /> Ironridge railing and Sunmodo Nano Mounts.The attachments can be attached up to 48" apart in <br /> roof zones 1, 2e, and 24" apart in roof zones 2n, 2r, 3e,&3r.The mounts should be staggered, <br /> where possible,to allow distribution of the design loads evenly to the structure.The mounts shall <br /> be installed with a min. 5/16"lag screw with minimum 2-5/16"thread length. <br /> Please see attached documents and contact me should you have any questions. <br /> Sincerely, <br /> D.
