The calculations were <br />done in accordance with the 2009 IBC, ASCE 7-05, 2005 NDS, and guidelines <br />stated in the Solar America Board for Codes and Standards. <br />For some of the components the SnapNrack test data was used to determine <br />capacity and section properties of materials. The test data was collected using <br />the procedures outlined in the 2009 BC Chapter 17. <br />The calculations were performed for die following wind, seismic, and snow load <br />combinations and building parameters. <br />• ASCE 7-05 wind speeds from 85 mph to 150 for B and C exposure <br />categories <br />• ASCE 7-05 Seismic Design Category E <br />• ASCE 7-05 Snow Loads up to 120 psf ground snow <br />• Buildings with mean roof heights up to 60 foot tilt angles / roof pitches <br />from 0 degrees to 60 degrees. <br />In our opinion the mounting system as outlined in the SnapNrack Series 100 PV <br />Mounting System Code Compliant Installation Manual 2012 is acceptable and <br />meets the loading requirements as stated above.
