Document #524734 Rev F, Vol. 8 1 SunPower Proprietary <br />InvisiMount Span Tables <br />Engineering Summary Letter <br />Volume: 8 <br />ASCE 7 Version: 7-16 <br />Module Type: A-Series / M-Series (66-cell) <br />Roof Attachment: Tile Roof <br />High Wind: No <br />High Snow: No <br />The Span Tables are divided into two Parts: <br /> Part 1: Simplified Tables (Wind Tunnel Loads) <br /> Part 2: General Tables (ASCE 7 Analytical Method) <br />Part 1 features spans based on forces on the InvisiMount system using exposure coefficients, GCp, provided by a <br />Wind Tunnel Test Report by Cermak, Petrka, & Petersen (CPP). These values provide a more accurate and <br />economical solution but apply to less configurations. It is recommended to use these values whenever possible, <br />and when not, to use the spans provided in Part 2. <br />Approved Attachments: <br />The following span tables are adequate for the following roof attachments: <br /> SunPower InvisiMount L-Foot attachment <br /> Pegasus Composite Shingle Roof Attachment <br />o And roof attachments with the following Load and Resistance Factor Design (LRFD) capacities: <br /> Tension – 1000lb <br /> Compression – 1000lb <br /> Shear – 390lb <br /> Pegasus Tile Roof Attachments, Generation 1 & 2 <br />o And roof attachments with the following Load and Resistance Factor Design (LRFD) capacities: <br /> Tension – 675lb <br /> Compression – 1000lb <br /> Shear – 300lb <br />Scope: <br /> Module orientations: Portrait & Landscape <br /> Gable and Hip roofs only with modules not in the overhang sections of the roof <br /> Roof heights <br />o 30ft (Part 1 only) <br />o 20-60ft (Part 2 only) <br /> Roof Slope <br />o 4:12 to 8:12 (Part 1 only) <br />o 2:12 to 12:12 (Part 2 only) <br /> Exposures Categories B, C, D <br /> 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 /> 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 />1931 W <br />Rd - 208/07/23
