<br />Projoct Do..riptioDl
<br />The project consists of the determination of the max span for the proposed rails to be
<br />used as a flush roof mounting 6y6tem for Photovoitaic (P\D modules. The solar
<br />designer, Solar Warehouse (SWH) has conrracred Engineered Power Solutions (EPS)
<br />to adiLess ihe slructural aspects of the rail, mainly rhe rail span of the proposed rail
<br />concepts- SWH has specified a rumber ofcommon deeign scenarios that EPS ha8
<br />used to determine the maximum sllowable rsil spans for the O) rail profiles
<br />proposed (Standard and Ecolite). These Ecenarios include design wind speed, wind
<br />expoBure categor]', design Found snow load, orientltion of module, tilt (pitah) ofthe
<br />roof/moduleg, roofzones, etc. SWH has also speciired a number ofdesign
<br />a66umptionc thal remain constanr for ali Ecenarios which are discussed in fufther
