MODULE INSTALLATION
Install modules where they are not
shaded by obstacles like buildings or
trees. Especially pay attention to
avoid partially shading the modules
by objects during the daytime. If a
part of the PV module is always
shaded, hot spot may occur and the
PV module may break down.
Water stains might be caused when
rain water remains on the glass
surface for a long time. To avoid
water stains, Panasonic recom-
mends to install panels at a slope
steeper than the water gradient.
Modules should be firmly fixed in
place in a manner suitable to with-
stand all expected loads, including
wind and snow loads.
The modules should be mounted
basically at the four (4) quarter
points by the means shown in Figure
1, and based on installation meth-
ods shown in Figure 5-1, 5-2.
Metals used in locations that are
exposed to moisture shall not be
employed alone or in combinations
that could result in deterioration or
corrosion.
Clearance 100mm between the roof
surface and module frame is re-
quired to allow cooling air to circu-
late around the back of the module.
This also allows any condensation or
moisture to dissipate. Install mod-
ules so that air can circulate be-
tween the roof and the module.
Do not contact a tip of a mounting
bolt to back sheet of the module
when fixing the module to the
mounting structure rail.
Appropriate material should be
used for mounting hardware (the
module frame, mounting structure,
and hardware) to prevent itself
from corrosion.
Please contact your Panasonic Au-
thorized Representative with ques-
tions regarding mounting profiles
for modules if needed.
