Notes: <br />x Tables are based on strength of the InvisiMount rail and approved roof attachment in the Engineering Summary <br />Letter of this document, in conformance with IBC and referenced standards. <br />x Maximum allowable cantilever is equal to 1/3 of the allowable span. <br />x Wind speeds are ultimate values in mph, as defined in ASCE 7. Wind pressure coefficients are derived from wind <br />tunnel testing in conformance with ASCE 7 Chapter 31. <br />x Tables are valid for mean roof height ≤ 30 ft, gable end width ≤ 40 ft, and ridge length ≤ 60 ft. <br />x Tables apply to any location on the roof, except that PV modules must be set back at least 10 inches from all <br />ridges and roof edges. <br />x User is responsible for verifying the strength of the roof. <br />x User is responsible for verifying the capacity of the module. Module pressures are provided above and are <br />derived from the Wind Tunnel Test Report. The user must confirm that the design capacities of the module are <br />greater than both the uplift and downforce pressured identified. <br />Document #524734 Rev G, Vol. 2 8 SunPower Proprietary <br /> Inputs INVISIMOUNT ALLOWABLE SPANS (IN) <br /> Slope→ 18.43 ° 22.62 ° 26.57 ° 30.26 ° 33.69 ° <br />Exposure B Speed↓ 4:12 5:12 6:12 7:12 8:12 <br />Ground Snow (psf) 0 90 96 96 96 96 96 <br />Height (ft) 30 95 96 96 96 96 96 <br />Seismic, Ss (g) 3.73 100 96 96 96 96 96 <br /> 105 96 96 96 96 96 <br /> 110 96 96 96 96 96 <br /> 120 96 96 96 96 96 <br /> 130 96 96 96 80 80 <br /> <br />UPLIFT MODULE PRESSURE (PSF) DOWNFORCE MODULE PRESSURE (PSF) <br />Slope → 18.43 ° 22.62 ° 26.57 ° 30.26 ° 33.69 ° Slope→ 18.43 ° 22.62 ° 26.57 ° 30.26 ° 33.69 ° <br />Speed↓ 4:12 5:12 6:12 7:12 8:12 Speed↓4:12 5:12 6:12 7:12 8:12 <br />90 -14 -14 -14 -14 -14 90 19 19 19 19 19 <br />95 -14 -14 -14 -14 -14 95 19 19 19 19 19 <br />100 -14 -14 -14 -14 -14 100 19 19 19 19 19 <br />105 -14 -14 -14 -14 -14 105 19 19 19 19 19 <br />110 -14 -14 -14 -14 -14 110 19 19 19 19 19 <br />120 -17 -17 -17 -17 -17 120 19 19 19 20 20 <br />130 -20 -20 -20 -21 -21 130 19 19 19 23 23 <br /> <br /> <br /> <br /> <br /> <br />613 W <br />1011108/29/23
