SPECIFICATIONS
Notes on Specifications
1)
Rated electrical characteristics are within
–5% to +10% of the values measured at
Standard Test Conditions (STC). STC
conditions are; Irradiance of 1000W/m
2
,
25°C cell temperature, and solar spectral
irradiance per IEC 60904-3. Note: At the
time of shipment, Panasonic guarantees
the output level of its modules to be -
0/+10%
against
Rated
Power
in
SPECIFICATIONS
based
on
factory
inspection at STC conditions.
2)
Under real conditions, a photovoltaic
module may experience conditions that
produce more current and/or voltage
than
reported
at
Standard
Test
Conditions. Therefore, the Isc value of
modules should be multiplied by a factor
of 1.25 to determine ampacity. An
additional factor of 1.25 may be required
for sizing conductors, fuses, disconnects,
etc. Please refer to section 690.8 of the
National
Electric
Code
(NEC)
for
guidelines. The Voc must be factored
according
to
the
lowest
recorded
operating temperature recorded for the
location where the modules will be
installed. Please refer to section 690.7 of
the NEC for more information regarding
voltage temperature factors.
3)
The current output for the modules
shown in the SPECIFICATIONS section is
measured at Standard Test Conditions.
These conditions may not be frequently
observed in actual practice.
Mechanical Loading
The modules should be mounted at the
four (4) quarter points by the means
shown in Figure 2.
This method offers a maximum load of
2,400 N/m2 (50PSF) in a static state on
the module surface.
Note: This mechanical loading value was
tested
using
the
mounting
device
specified in section “Notes on Installation”.
UNPACKING AND HANDLING
Do not hit the back sheet of a module by
the connector when unpacking and
handling.
To avoid the damage of the back sheet
by connector, fix the cables to the frame
with tape after unpacking. (see below)
After fixing the cable to the frame, do not
stack modules to avoid the damage of the
cable.
Do not handle modules by their cables or
junction box. Handle them by the frame
with both hands in any situation.
WIRING
General
All wiring should be done in accordance
with applicable electrical codes.
Wiring methods should be in accordance
with the NEC in USA or CEC in Canada.
A qualified, licensed professional should
do all wiring.
Wiring should be protected to help ensure
personal safety and to prevent damage.
All modules connected in series should be
of the same model number and/or type.
Do not connect modules in parallel
without using connection devices that
connect to appropriate FUSE for each
series string or each module.
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 number of modules that can be wired
in series is recommended to be seven (7)
or fewer. If connecting eight (8) modules
in
series,
check
local
temperature
conditions
and
follow
the
National
Electric
Code
(690.7)
to
ensure
compliance
with
maximum
voltage
limitations.
Modules are not designed for “off-grid”
or battery charging systems, because of
their operating voltage. Therefore, it is
not recommended to use them for
charging batteries.
These modules contain factory installed
bypass diodes. If these modules are
incorrectly connected to each other, the
bypass diodes, cable, or junction box may
be damaged.
The PV module comes pre-wired. Each
module has two #12 AWG type PV-wire
stranded sunlight resistant output cables
each terminated with connectors. The
positive (+) terminal has a male connector
while the negative (-) terminal has a
female connector. The module wiring is
solely for series connections only, i.e. male
(+) to female (-) interconnections. When
making field wiring connections to the
pre-attached
connectors
use
only
approved connectors from Table.1.
Array Wiring
The term “array” is used to describe the
assembly of several modules on a support
structure with associated wiring.
Use copper wire which insulation is
sunlight resistant and can withstand the
maximum possible system open circuit
voltage.
Interconnection of modules must be
performed in a professional fashion.
Wires should be secured and only
reasonable slack should be allowed.
Check local codes for requirements.
Earth Ground Wiring
A module with exposed conductive parts
is considered to be in compliance with UL
1703 only when it is electrically grounded
in
accordance
with
the
instructions
presented below and the requirements of
the National Electrical Code.
All modules should be grounded. All
structures or metallic components in
direct contact with the modules or electric
wires should be properly grounded too.
To avoid the hazards of electric shock or
fire, modules should be grounded by the
frame only at the locations marked in this
manual (see grounding methods below).
The array frame shall be grounded in
accordance with NEC Article 250 (USA) or
the CEC in Canada.
Bonding shall be by a positive means, such
as clamping, riveting, bolted or screwed
connectors, or welding, soldering or
brazing. If the bonding means depends
upon screw threads two or more screws
or two full threads of a single screw must
engage the metal
Great care should be exercised to ensure
that corrosion caused by the grounding
means be avoided.
Corrosion can increase the resistance of
the grounding connection on the module,
or
can
even
cause
the
grounding
connection to fail entirely. Corrosion can
be caused by the effects of weather,
humidity, dirt and so on. It can also be
caused when two dissimilar metals are in
contact (galvanic reaction).
The
module
frame
material
is
aluminum/magnesium alloy.
