INSTALLATION
General
Please read this guide completely
before
installing or using your
Panasonic PV modules. This section
contains
important electrical and
mechanical specifications.

Modules should be firmly fixed in
place in a manner suitable to
withstand
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.

Install modules where they are not
shaded by obstacles like buildings
and trees. Pay special attention to
avoid partially shading the modules
by objects during the daytime.

If needed, contact an Authorized
Representative
with questions
regarding mounting profiles for
Panasonic HIT
®
.
Notes on Installation

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 moisture
to dissipate. Install modules with a
minimum
of 1 inch clearance
between the roof surface and the
modules so that air can circulate.

Panasonic recommends the
installation method and mounting
profile shown in Figure 1

A module should be attached on a
mount or support structure rail by
corrosive-resistant metal clamps.

The clamps should be made of
aluminum alloy or other material
that will reasonably protect against
a risk of electrolytic corrosion.

Recommendation of bolt torque
range: 16N.m to 20N.m

