SOLG . N <br /> P O W E R <br /> RT Mini Connection Calculation <br /> This calculation justifies the connection of the solar panels to existing roof members, by showing the connection <br /> capacity is equal to or greater than the uplift force demands. <br /> Connection Demand <br /> Spacing perpendicular to rail 32.5 in 1/2 panel length <br /> Spacing parallel to rail 48 in Max spacing <br /> Effective Wind Area on each connection 10.8 ft2 <br /> Roof Angle 32 degrees 30LAR <br /> ROOFINO/ <br /> Wind Speed 110 mph LFOOT <br /> Exposure Coefficient, K, 0.95 <br /> Topographic Factor, K,t '1 ROOFNI <br /> MINI <br /> CHIKO <br /> Directionality Factor, Kd 0.85 19 Rld <br /> Elevation Factor, Ke 1.00 <br /> Velocity Pressure, q, 25.0 psf Mount throughro fsh g , <br /> ex st w roftem <br /> Zone 1 Zone 2 Zone 3 <br /> GCp(max) 1.24 1.47 1.78 <br /> Exposed Panels?
