6MODULE INSTALLATION• Install modules where they are not shaded byobstacles like buildings or trees. Especially payattention to avoid partially shading the modulesby objects during the daytime. If the PV moduleis always partly shaded, hot spots may occurwhich can destroy the PV module.• Water stains might be caused when rain waterremains on the glass surface for a long time. Toavoid water stains, Panasonic recommends toinstall modules at a slope steeper than thewater gradient.• Modules should be firmly fixed in place in amanner suitable to withstand all expectedloads, including wind and snow loads.• The modules should be mounted basically atthe four (4) quarter points by the means shownin Figure 1, and based on installation methodsshown in Figure 4.• Metals used in locations that are exposed tomoisture shall not be employed alone or incombinations that could result in deteriorationor corrosion.• Clearance of 10cm between the roof surfaceand module frame is required to allow coolingair to circulate around the back of the module.This also allows any condensation or moistureto dissipate. Install modules so that air cancirculate between the roof and the module.• Do not contact a tip of a mounting bolt to theback sheet of the module when fixing themodule to the mounting structure rail.• Appropriate material should be used formounting hardware (the module frame,mounting structure, and hardware) to preventitself from corrosion.• Please contact your Panasonic AuthorizedRepresentative with questions regardingmounting profiles for modules if needed.Solar moduleModuleMounting Structure RailM8 BoltSpring washerM8 NutFlat washerFlat washerSpring washerSolar moduleMetal clamp B(2 places)Metal clamp A(2 places)Mounting structure railFigure 5.
