SOLGE'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 <br />Spacing parallel to rail <br />Effective Wind Area on each connection <br />Roof Angle <br />Wind Speed <br />Exposure Coefficient, K, <br />Topographic Factor, K, <br />Directionality Factor, Kd <br />Elevation Factor, Ke <br />Velocity Pressure, q, <br />GCp (max) <br />Exposed Panels?
