SOLGr- 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. Minimum embedment is 1.5 inches, <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 18 degrees 30!^R PANEL/ <br /> ROOFING <br /> Wind Speed 110 mph �FGGr <br /> Exposure Coefficient, K, 0.85 Q <br /> Topographic Factor, K, 1 ROOINI <br /> MINI <br /> CHIKO <br /> Directionality Factor, Kd 0.85 70 Rell <br /> Elevation Factor, Ke 0.99 <br /> Velocity Pressure, q, 22.1 psf Mom thmugh roof sheathing <br /> into existing rafters <br /> Zone 1 Zone 2e Zone 3 <br /> GCp(max) 1.80 2.57 2.57 <br /> Exposed Panels?(YE= 1.5) No No No <br /> Pressure Equalization Factor,V, 0.79 0.79 0.79 <br /> Uplift Force 31.3 44.6 44.6 psf <br /> Max.
