SUNPOWER CORPORATION Document #524734 Rev G <br />SPAN TABLES, INVISIMOUNT Template FILE-074910, Ed. 2 <br /> <br /> <br />Document #524734 Rev G, Vol. 2 1 SunPower Proprietary <br /> <br />InvisiMount Span Tables <br />Engineering Summary Letter <br /> <br />V 2 <br /> 7-16 <br />22 Sq. Ft. Module <br />Composite Shingle <br /> No <br /> No <br />The Span Tables are divided into two Parts: <br />x Part 1: Simplified Tables (Wind Tunnel Loads) <br />x Part 2: General Tables (ASCE 7 Analytical Method) <br />Part 1 features spans based on forces on the InvisiMount system using exposure coefficients, GCp, <br />provided by a Wind Tunnel Test Report by Cermak, Petrka, & Petersen (CPP). These values provide a <br />more accurate and economical solution but apply to less configurations. It is recommended to use these <br />values whenever possible, and when not, to use the spans provided in Part 2. <br /> <br />The following span tables are adequate for the following roof attachments: <br />x SunPower InvisiMount L-Foot attachment <br />x Pegasus Composite Shingle Roof Attachment <br />o And roof attachments with capacities equal to or greater than all of the following Load <br />and Resistance Factor Design (LRFD) values: <br />ƒ Tension – 1000lb <br />ƒ Compression – 1000lb <br />ƒ Shear – 390lb <br />x Module orientations: Portrait & Landscape <br />x Gable and Hip roofs only with modules not in the overhang sections of the roof <br />x Roof heights <br />o 30ft (Part 1 only) <br />o 20-60ft (Part 2 only) <br />x Roof Slope <br />o 4:12 to 8:12 (Part 1 only) <br />o 2:12 to 12:12 (Part 2 only) <br />x Exposures Categories B, C, D <br />x Basic Wind Speeds: <br />o ASCE 7-10: 110-140mph – High Wind: 145-180mph <br />o ASCE 7-16: 90-130mph – High Wind: 135-180mph <br />x Ground Snow Loads: <br />o 0-60psf (10psf increments) <br />o High Snow Volumes: 80-200psf (20psf increments) <br />o High Wind Volumes: 0psf <br />1402 W Meriday Ln - <br />201816051/10/2024
