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.

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 5.

Figure 5 shows using a bolt and nut
for mounting.

Do not contact a tip of a mounting
bolt to back sheet of the module
when fixing the module to the
mounting structure rail.

Recommendation of bolt torque: 10
ft-lbs.

Figure 5 shows that a module
should be attached on a mount or
support structure rail by corrosive-
resistant metal clamps.

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 of an improper materi-
al or size.

Please contact your Panasonic Au-
thorized Representative with ques-
tions regarding mounting profiles
for modules if needed.
