SM SOLAR <br />MOUNT System Certification PAGE <br />APPENDIX A A <br />The SOLARMOUNT system has been certified and listed to the UL 2703 standard (Rack Mounting Systems and Clamping Devices for Flat-Plate Photovoltaic <br />Modules and Panels). This standard included electrical grounding, electrical bonding, mechanical load and fire resistance testing. <br />In conducting these tests, specific modules are selected for their physical properties so that the certifications can be broadly applied. The following lists the <br />specific modules that were tested and the applicability of those certifications to other modules that might come onto the market. PV modules may have a <br />reduced mechanical load rating, independent of the SM load rating. Please consult the PV module manufacturer's installation guide for more information. <br />In addition to UL 2703 certification, Unirac performs internal testing beyond the requirements of certification tests in order to establish system functional <br />limits, allowable loads, and factors of safety. These tests include functional system tests, and destructive load testing. <br />Mechanical Load Test Modules System Level Fire Classification <br />The modules selected for UL 2703 mechanical load testing were <br />selected to represent the broadest range possible for modules on <br />the market. The tests performed cover the following basic module <br />parameters: <br />The system fire class rating requires installation in the manner <br />specified in the SOLARMOUNT Installation Guide. SOLARMOUNT <br />has been classified to the system level fire portion of UL2703. <br />Class A system level fire performance is inherent in the <br />SOLARMOUNT design, and no additional miti-gation measures are <br />required. The fire classification rating is only valid on roof pitches <br />greater than 2:12 (slopes ≥ 2 inches per foot, or 9.5 degrees). <br />There is no required minimum or maximum height limitation <br />above the roof deck to maintain the system fire rating for <br />SOLARMOUNT. Module Types & System Level Fire Ratings are <br />listed below: <br />• Frame thicknesses greater than or equal to 1.0 mm <br />•Basic single and double wall frame profiles (some <br />complex frame profiles could require further analysis to <br />determine applicability) <br />• Clear and dark anodized aluminum frames <br />Tested Modules <br />Module <br />Manufacturer <br />Model/Series Area <br />[sqft] <br />UL2703 Certification <br />Load Ratings <br />Hyundai HiS-S325TI 21.06 Down– 113 PSF, Up – 50 PSF <br />Down-Slope – 15 PSF <br />SunPower SPR-P19-395-COM 22.20 Down– 113 PSF, Up – 50 PSF <br />Down-Slope – 15 PSF <br />First Solar FS-6xxx-P 27.12 Down– 33.9 PSF, Up – 33.9 PSF <br />Down-Slope – 16.5 PSF <br />Rail Type Module Fire <br />Type <br />System <br />Level <br />Fire Rating <br />Rail <br />Direction <br />Module <br />Orientation <br />Mitigation <br />Required <br />Standard <br />Rail <br />1, 2, 3 w metal <br />frame, 10 w metal <br />frame, 19, 22, 25, <br />29, & 30 <br />Class A, B, <br />& C <br />East-West <br />North-South <br />Landscape <br />OR <br />Portrait <br />None <br />Required <br />Light Rail 1 & 2 Class A, B, <br />& C <br />East-West <br />North-South <br />Landscape <br />OR <br />Portrait <br />None <br />Required <br />2110 W 7th St - <br />2017778512/28/22
