Notes: <br />x Tables are based on strength of the InvisiMount rail and approved roof attachment in the Engineering Summary Letter <br />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 ASCE 7 <br />Chapter 30. <br />x User is responsible for verifying the strength of the roof. <br />x User is responsible for verifying the capacity of the module. Refer to the section of this document titled “Module <br />Pressure Calculation”, or the appropriate ASCE code (7-10 or 7-16), for instructions on calculating the uplift and <br />downforce module pressures. <br />Document #524734 Rev G, Vol. 2 33 SunPower Proprietary <br />Exposure B <br />Ground Snow (psf) 15 <br />Roof Height (ft) 20 <br /> INVISIMOUNT ALLOWABLE SPANS - ZONE 1 (IN) <br />Slope → 9.46 ° 14.04 ° 18.43 ° 22.62 ° 26.57 ° 30.26 ° 33.69 ° 36.87 ° 39.81 ° 42.51 ° 45 ° <br />Speed↓ 2:12 3:12 4:12 5:12 6:12 7:12 8:12 9:12 10:12 11:12 12:12 <br />90 72 72 80 80 80 80 80 80 96 96 96 <br />95 72 72 80 80 80 80 80 80 96 96 96 <br />100 72 72 80 80 80 80 80 80 96 96 96 <br />105 72 72 80 80 80 80 80 80 96 96 96 <br />110 72 72 80 80 80 80 80 80 96 96 96 <br />120 72 72 80 80 80 80 80 80 96 96 96 <br />130 72 72 80 80 80 80 80 80 80 80 80 <br /> <br /> INVISIMOUNT ALLOWABLE SPANS - ZONE 2 (IN) <br />Slope → 9.46 ° 14.04 ° 18.43 ° 22.62 ° 26.57 ° 30.26 ° 33.69 ° 36.87 ° 39.81 ° 42.51 ° 45 ° <br />Speed↓ 2:12 3:12 4:12 5:12 6:12 7:12 8:12 9:12 10:12 11:12 12:12 <br />90 72 72 80 80 80 80 80 80 96 96 96 <br />95 72 72 80 80 80 80 80 80 96 96 96 <br />100 72 72 80 80 80 80 80 80 96 96 96 <br />105 72 72 80 80 80 80 80 80 96 96 96 <br />110 72 72 80 80 80 80 80 80 96 96 96 <br />120 72 72 80 80 80 80 80 80 96 96 96 <br />130 72 72 72 80 80 80 80 80 80 80 80 <br /> <br /> INVISIMOUNT ALLOWABLE SPANS - ZONE 3 (IN) <br />Slope → 9.46 ° 14.04 ° 18.43 ° 22.62 ° 26.57 ° 30.26 ° 33.69 ° 36.87 ° 39.81 ° 42.51 ° 45 ° <br />Speed↓ 2:12 3:12 4:12 5:12 6:12 7:12 8:12 9:12 10:12 11:12 12:12 <br />90 72 72 80 80 80 80 80 80 96 96 96 <br />95 72 72 80 80 80 80 80 80 96 96 96 <br />100 72 72 80 80 80 80 80 80 96 96 96 <br />105 72 72 80 80 80 80 80 80 96 96 96 <br />110 72 72 80 80 80 80 80 80 96 96 96 <br />120 72 72 72 80 80 80 80 80 80 80 80 <br />130 64 64 64 72 72 80 80 80 80 80 80 <br /> <br />613 W <br />1011108/29/23
