3
specifications needed before using
modules.
Modules should be firmly fixed in
place in a manner suitable to
withstand
all
expected
loads,
including wind and snow loads.
For a non-integral module or panel,
the assembly is to be mounted over
a fire resistant roof covering rated
for the application.
Appropriate material should be
used for mounting hardware to
prevent
the
module
frame,
mounting structure, and hardware
itself from corrosion.
Install modules where they are not
shaded by obstacles like buildings
and trees. Especially pay attention
to avoid partially shading the
modules by objects during the
daytime.
Please contact your Panasonic
Authorized Representative with
questions
regarding
mounting
profiles for modules if needed.
In case of installing modules,
junction box should be upper side.
Module’s back surface should be
toward the surface.
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 4 inch clearance
between the roof surface and the
modules so that air can circulate.
We
recommend
installation
methods shown in Figure 1. In
some areas, local electrical codes
may govern the installation and
use of modules.
The following information is provided
to
help
customers
obtain
good
performance
without
exceeding
a
module’s
operating
conditions
or
warranty parameters.
Additional output power from the
back face of the panel can be
increased or decreased depending
upon angles of installation, height
from
surfaces,
shade
from
structures or rails, and the albedo
of surrounding surfaces.
The height of a module above a
surface affects the power potential
of the module’s back face.
When it is possible, maximize the
height of modules above surfaces
in order to maximize ambient light
beneath the modules.
Always position support structures
and rails along the edges of a
module, or between modules, and
do not allow rails to shade a
module’s back surface.
Light colored surfaces reflect more
light than dark colored surfaces.
Installing
VBHN225DJ06
series
over light colored surfaces will
increase
the
output
power
potential from the back side.
Operating Conditions
Panasonic recommends that modules
be operated within the following
Operating Conditions. An installation
location with conditions beyond the
Operating Conditions or with other
Special Conditions (see below) should
be avoided. Operating Conditions of
Panasonic modules are as follows:
1)
The modules should be operated
only in terrestrial applications. No
space or other Special Conditions
(see below).
2)
The ambient temperature should
be within –20°C (-4°F) to 40°C
(104°F).
3)
The relative humidity should be
within 45% to 95%.
4)
The wind pressure load of the
installation site should be less than
3,100 N/m
2
(64PSF)

This
value
is
based
on
Panasonic standard.
Special Conditions
1)
The ambient temperature and
installation place are different from
the
recommended
Operating
Conditions.
2)
Salt damage is severe at the
installation place.
3)
Hail and snow damage is excessive
at the installation place.
4)
Sand and dust damage is excessive
at the installation place.
