Installing SF System Safe, efficient SF System installation involves three principal tasks: A. Laying out the installationareaand planning formaterial conservation. B. Installing footings andrails, beginning with the lowest rowand moving up the roof. C. Placing modules and cap strips, beginning with the highestrow and moving down the roof. The following illustrated steps describe the procedure in detail. Before beginning, please note these important considerations. [1.3.] Installer responsibilities: Please review this manual thoroughly before installing your SF System. SunPower also provides a limited warranty on SF System products (page 14). The installer is solely responsible for: • Complying with all applicable local or national building codes; • Ensuring that SunPower and other products are appropriate for the particular installation and the installation environment; • Ensuring that the roof, its rafters, connections, and other structural support members can sup- port the array under allload conditions (this total assembly is referred to as the roof rafter struc- ture); • Using only SunPower parts and installer-supplied parts as specified by SunPower (substitution of parts may void the warranty); • Ensuring that lag screws have adequate pullout strength and shear capacities as installed; • Verifying the strength of any alternate mounting used in lieu of the lag screws; • Maintaining the waterproof integrity of the roof, including selection of appropriate fiashing; • Ensuring safe installation of all electrical aspects of the PV array. Footing, must be tagged into #tructural members. Never attach them to the decking alone, whfch leaves both the amy and roofsusceptible to severe damage. For array widths or lengths greater than 32 feet, contact SunPDwerconcerning thermalexpansion iSSUeS. Sample layout, illustrated in figuie 4 Assumpdons: 12 modules (60' x 361, arranged In 3 rOWs of4 modules Array width = 144- (36-modulewidth14 modulesperrow) Amy length - 180- (60- module length x 3 raws) +3'(le'endrai}widrt·1*2 rails) + 114' (44 - berwerynodule ran width x 2 rails) - 184;M 1. Laying out the Installation area: Always install SF System rails perpendicular to rafters. (These instructions assume typical rafters that run from the gutter to the peakofthe roof. If this is not the case, contact SunPower.) Rails are typically mounted horizontally (parallel to the lower edge of the rooD, and must be mounted within 10 degrees of horizontal. 1,eave adequate room to move safelyaround the arrayduring installation. During module installation, you will need to slide one module in each row about a foot beyond the end of the rails on one side. Using the number of rows and the number of modules per row in >our installation, determine the size of your array area following Figure 2. 1 M - al each end of array . -r Roof peak %.
