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 modules 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.
Metals used in locations that are
exposed to moisture shall not be
employed alone or in combinations
that could result in deterioration or
corrosion.
The clamps should be made of alu-
minum alloy or other material that
will reasonably protect against a risk
of electrolytic corrosion.
Clearance between the roof surface
and module frame is required to
allow cooling air to circulate around
the back of the module. This also
allows any condensation or mois-
ture to dissipate. The required
clearance between the roof surface
and the module is more than 4 inch.
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 10
Figure 10 shows using a bolt and
nut for mounting.
Do not contact allow the bolt to
contact the back sheet of the mod-
ule when fixing the module to the
mounting structure rail.
Do not allow the microinverter to
interfere with the mounting struc-
ture rail when fixing the module to
the mounting structure rail. (See
Figure 11)
Recommendation of bolt torque: 10
ft-lbs.
Appropriate material should be
used for mounting hardware (the
module frame, mounting structure,
and hardware) to prevent itself
from corrosion.
Panasonic does not provide a war-
ranty for clamps. The module war-
ranty Panasonic provides shall be
voided if clamps selected by the
customer are an improper material
or size.
Please contact your Panasonic Au-
thorized Representative with ques-
tions regarding mounting profiles
for modules if needed.

Ridge clamps with the specifications
