ENGINEERED POWER SOLUTIONS <br />72 SOUTH MAIN STREET, SUITE A <br />TEMPLETON, CA 93465 <br />Solar Warehouse Rail Analysis – Generic Packet <br />Design Parameter Notes: <br />1) Modules of different sizes and/or weights than those specified are not included in <br />this analysis and shall be checked individually by a registered professional engineer. <br />Results shown will be conservative for most 60 cell modules with areas smaller than <br />the 72 cell module listed in this packet. <br />2) It is the solar designer/installer or owner’s responsibility to determine the site <br />specific design parameters of each site based on the current governing building code <br />and/or local jurisdiction’s requirements. <br />3) The site is assumed to have no topographic effects, i.e. it is not on a bluff, cliff, <br />mesa, escarpment, upper half of a hill, or any other condition as described in the <br />governing building code that would require a Topographic Factor other than 1.00. <br />4) Wind Exposure Categories considered are “B” and “C” as defined in ASCE 7. Wind <br />Exposure Category “D” (sites overlooking bodies of water, mudflats, salt flats, and/or <br />ice) has not been considered in this analysis. A site specific analysis is required for <br />Wind Exposure “D” sites. It is the designer/installer, a 3rd party engineer, governing <br />jurisdiction, or owner’s responsibility to determine the wind exposure category of the <br />site. <br />5) The building height listed is defined as the distance between the highest point of <br />the PV system and grade. If the building has varying grade elevations, the lowest <br />grade elevation shall be used. Projects where the height is greater than 30 ft. require <br />a site specific analysis. <br />6) It is assumed the roof is “Partially Exposed” as described in ASCE 7. This <br />assumption is conservative for buildings with “Fully Exposed” roofs. For buildings <br />with “Sheltered” roofs, a site specific analysis is required. <br />7) The existing structure is considered to be Risk Category II structure (or less). <br />Therefore, the snow importance factor (Is) is 1.00 per Table 1.5-2 in ASCE 7. <br />Buildings considered to be a Risk Category III and IV structure shall have the rail <br />lengths be evaluated by a registered professional engineer on a site specific basis. <br />8) It is assumed that the rail is a single span conditions with the rail cantilevering <br />on each side by at least 25% of the adjacent span but no more than 40% of the <br />adjacent span. <br />Page 9 <br />2004 W Picasso - <br />2018062008/29/23
