Notes on Specifications
1)
Rated electrical characteristics are
within from +10% to -10% of the
values measured at Standard Test
Conditions (STC). Irradiance of
1000W/m
2
, 25
o
C cell temperature,
and solar spectral irradiance per
IEC 60904-3.
2)
Under
normal
conditions,
a
module
may
experience
conditions
that
produce
more
current and/or voltage than
reported at standard component
test conditions. Accordingly, the
values of Isc and Voc should be
multiplied by a factor of 1.25 when
determining
voltage
ratings,
conductor capacities, fuse sizes,
and size of controls connected to
the module output.
VBHN225DJ06 series are bifacial
photovoltaic module, so the factor
of Isc need to maximized 1.63
(bifacial
effect
1.3
x
1.25)
depending
on
the
installation
methods and conditions.
3)
The current output for the modules
shown
in
the
Figure

is
measured
at
Standard
Test
Conditions. These conditions may
not be frequently observed in
actual practice.
Application class of product
Panasonic HIT PV modules are applied
to application class A. Application class
A for modules are defined as follows:
Class A: General access, hazardous
voltage, hazardous power applications
Module rated for use in this application
class may be used in systems operating
at greater than 50 V DC or 240 W,
where
general
contact
access
is
anticipated.
Modules
qualified
for
safety through this part of IEC 61730-1
and IEC 61730-2 and within this
application class are considered to
meet the requirements for safety class
II.
Fire class of product
Panasonic HIT PV modules fill the fire
class C that provides to IEC61730-2.
Class C roof coverings are effective
against light fire test exposures. Under
such exposures, roof coverings of this
class afford a light degree of fire
protection to the roof deck, do not slip
from position, and are not expected to
produce flying brands.
Mechanical Loading
The modules should be mounted
basically at the four (4) quarter
points by the means shown in
Figure 2.
This method offers a maximum
load of 5,400N/m
2
(112PSF, in a
static state) on the module surface.
Certification
VBHN225DJ06 series comply with the
requirements of IEC61215, IEC61730-1
and IEC61730-2.
Wiring
General
All wiring should be done in
accordance
with
applicable
electrical codes.
All wiring should be done by a
qualified, licensed professional.
Wiring should be protected to help
ensure personal safety and to
prevent its damage.
All modules connected in series
should be of the same model
number and/or type.
Do not connect modules in parallel
without using a connection box.
Do not disconnect terminals while
modules generate electricity and
connect electrical load to avoid the
hazard of electrical shock.
To avoid the hazard of electric
shock and sparks, please connect
each cable after confirming the
polarity of them is correct.
Cable conduits should be used in
locations where the wiring is
inaccessible to children or small
animals.
Module Wiring
The
maximum
number
of
VBHN225DJ06 series that can be
wired in series is ten (10).
Modules shall not be wired in
parallel without maximum over
current protection.
When installing a PV array, the
system design must be completed
with reference to the module
electrical specifications for proper
selection
of
inverters,
fuses,
breakers,
charging
controllers,
batteries and other storage devices.
These modules contain factory
installed bypass diodes. If these
modules are connected each other
incorrectly, the bypass diodes,
cable, or junction box may be
damaged.
Array Wiring
The term “array” is used to
describe the assembly of several
modules on a support structure
with associated wiring.
Use copper wire that is sunlight
resistant
and
is
insulated
to
withstand the maximum possible
system open circuit voltage.
Check
your
local
codes
for
requirements.
Earth Ground Wiring
The kind of the earth construction
shall conform to IEC61730-1.
Grounding should be carried out by
the attachment to the module or
array frame, to avoid the hazards
of electric shock or fire.
Module Terminations
A junction box as a terminal
enclosure is equipped for electrical
connections on modules.
Modules are equipped with MC
TM
plugs(PV-KBT3II-UR, PV-KST3II-UR)
as a terminal enclosure. Use these
MC
TM
plugs
for
electrical
connections.
If
two
or
more
separable
connectors are provided, they shall
be configured or arranged so that
the other and vice-versa will not
accept the mating connector for
one, if it will result in an improper
connection.
Please contact your Panasonic
Authorized Representative with
questions regarding other electrical
connections if needed.
Junction Box and Terminals
Modules
equipped
with
one
junction box contain terminals for
both positive and negative polarity,
and bypass diodes.
One terminal is dedicated to each
polarity (with the polarity symbols
engraved onto the body of the
junction box).
Conduit
For
applications
where
wire
conduits are used, follow the
applicable
codes
for
outdoor
installation of wires in conduits.
Minimum diameter of wire conduit
is 3.5 mm
2
.
Verify that all fittings are properly
installed to protect wires against
damage and prevent moisture
intrusion.
