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 ftz <br /> Roof Angle 39 degrees 30LAR PANEL/ <br /> ROOFING <br /> Wind Speed 110 mph LFOOT <br /> Exposure Coefficient, K, 0.96 <br /> Topographic Factor, K, 1 ROOF <br /> MINI <br /> CHIKO <br /> Directionality Factor, Kd 0.85 7#R.11 <br /> Elevation Factor, Ke 1.00 <br /> Velocity Pressure, q, 25.2 psf MwnIMnx,gh=fshealh,,g <br /> into existing Fetters <br /> Zone 1 Zone 2r Zone 3 <br /> GCp(max) 1.38 1.89 2.16 <br /> Exposed Panels?(y,= 1.5) No No No <br /> Pressure Equalization Factor,Ya 0.79 0.79 0.79 <br /> Uplift Force 27.3 37.5 42.7 psf <br /> Max.
