Weight: 43lbs
Width: 39.05 inches
Length: 64.96 inches
Area: 17.6sq ft
Solar System Values
Mount system weight: 30lbs
modules weight: 6 x 43 = 258lbs
Total weight: 258 + 30 = 288lbs
Array area: 6 x 17.6 = 105.6 sq ft
Equation
Withdraw resistence for 5/16" lag screw in douglas ®r is 274 lb/in
Distributed dead load = total weight/total array area
Point dead loading = total weight/ #standoff
Up lift pressure = [(pressure x array area) - total weight]/# standoff
Calculation
Withdraw resistence = 2.5 x 274 = 685 lbs
Distributed dead load = 288/105.6 = 2.7 lbs/sq ft
Point dead loading = 288/6 =36 lbs per attachement
Up lift pressure = [(30 x 105.6) - 288] / 8 = 360lbs < 685lbs O.K
