Use the maximum absolute value of the three <br />downkrce cases and the Uplift Case. We assume each module <br />issupporteB by two rails. <br />w = PB/2 <br />w = Distributed Load (pounds per linearfoot, PW <br />B = Module Length Perpendicular to Rails (ft) <br />P = Total Design Pressure (pounds persquarefoot psf) <br />Table 8. L-Foot SolarMount Series Rail Span <br />SM - SolarMount HD - SolarMount Heavy Duty <br />Step 3: Determine Rail Span/L-Foot Spacing <br />Using the distributed load, w, from Part 11, Step 2, look up the <br />allowable spans, L, for each Unirac rail type, SolarMount (SM) <br />and SolarMount Heavy Duty (HD). <br />The L-FooL SolarMount Series Rail Span Table uses a single <br />L-foot connection to the roof; wall or stand-off.
