All instructions should be read and
understood before attempting to
install, wire, operate, and maintain
the module.
The installation of modules
requires a great degree of skill
and should only be performed by
qualified licensed professionals,
including, without limitation,
licensed contractors and licensed
electricians.
The installer assumes the risk of
all injury that might occur during
installation, including, without
limitation, the risk of electric
shock.
Before installing modules, contact
the appropriate authorities to
determine permissions, installation
and inspection requirements,
which should be followed.
Be sure that the construction or
structure (roof, etc.) where the
modules are being installed has
enough strength.
Both roof construction and
module installation design have
an effect on the fire resistance of
a building. Improper installation
may contribute to fire hazards.
Additional devices such as ground
fault, fuses, and disconnects may
be required.
For a non-integral module or
module, the assembly is to be
mounted over a fire resistant roof
covering rated for the application.
For modules mounted on roofs,
special construction or structures
may be required to help provide
proper installation support.
Do not install the module where
flammable gases or vapors are
present.
Do not use modules of different
specifications in the same system.
Follow all safety precautions of
other system components used.
In some areas, local electrical
codes may govern the installation
and use of modules.

The modules generate DC
electrical energy when exposed to
sunlight or other light sources, so
cover the entire front surface of
the modules with a dense, opaque
material such as a cardboard box,
during installation and handling of
the modules.
The shock hazard increases as
modules are connected in parallel,
producing higher current, and as
modules are connected in series,
producing higher voltages.
The shock hazard increases as
modules rated for maximum
system voltage in excess of 50 V.
Wear suitable clothing, gloves
and guards to prevent from direct
contact with 30 VDC or greater.
Work only in dry conditions, with
dry modules and dry tools.
Children and unauthorized persons
should not be allowed near the
installation of modules.
Do not puncture or damage the
backsheet of a module. Do not
use the PV module and make
a replacement, when scratch
exposing conductive part is found
on the backsheet.
Do not disassemble the module, or
remove any parts installed by the
manufacturer.
Do not open a junction box’s lid.
Do not touch the junction box
terminals.
Do not change the wiring of bypass
diodes.
Do not connect or disconnect
terminals while modules generate
electricity and connect electrical
load.
Never leave a module unsupported
or unsecured.

Module Specifications
•
Module specifications are shown in Table 1, 2 and Figure 1, 2, 3. (Electrical specifications, mechanical specifications,
module dimensions)
•
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 ambient 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.

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.
GR

•
GR
2) The operating temperature must be
within -40ºF(-40ºC) to 185ºF(85ºC).
•
UNPACKING AND HANDLING
• Do not hit the back sheet of a
module by the connector when
unpacking and handling.
• Please do not expose the connector
the rain water and dust.
• To avoid the damage of the back
sheet by the connector, fix the
cables to the frame with tape after
unpacking. (refer Figure 5)
• Do not handle modules by their
cables or junction box. Handle
them by the frame with both hands
in any situation.

caused by mechanical abrasion or
grazing animals.
Protect connectors from falling or
dropping water by locating them
directly beneath a module.
Cables must be firmly secured
to the structure, without overtightening, as this can deform the
cable insulation using UV-resistant
cables.
When securing the connector, place
it so that it has with sufficient air
circulation all around. This allows
the connector to dry effectively
and avoids the risk of damage or
degradation of the connection.
Secure the cable either side of the
connectors to ensure no stress is
exerted on the connector casing or
cable entry.
To enable correct cooling and
drying of the connectors, do
not add extra protection to the
connector e.g., heat shrink, grease
or tape.

CABLE MANAGEMENT
To ensure a long life span of the cables
and reduce the potential for damage to
the cables, follow the instructions
below:
•
•
•
To prevent stress on the junction
box casing, ensure the cable exits
the junction box in a straight line
before any bend in the cable.
The cables must have a minimum
bending radius of 1.2 in (30 mm)
to avoid damage to the insulation
(refer Figure 6).
Ensure cables do not hang loose
where they may be damaged
through friction or stress, e.g.,
Figure 6. Minimum cable bend radius

MODULE INSTALLATION
EverVolt modules are designed for
capturing solar radiation and can be
installed where they conform to all
local structural regulations. If installing
EverVolt modules in overhead or
vertical constructions, the installer
must ensure that all local building
codes and regulations specific to such
installations are correctly followed. The
IP rating of the junction box provides a
level of protection that allows modules
to be mounted in any orientation.
There are different options for
securing EverVolt modules depending
on the design of the array. Mounting
hardware is not supplied by Panasonic.
Ensure the mounting structure can
withstand anticipated wind and snow
loads. Follow the mounting hardware
manufacturer’s instructions and
recommendations at all times.
•
•
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. If
a part of the PV module is always
shaded, hot spot may occur and the
PV module may break down.
Water stains might be caused
when rain water remains on the
glass surface for a long time. To
avoid water stains, Panasonic
recommends to install modules
at a slope steeper than the water
gradient.
•
•
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.
USE OF RAILS AND CLAMPS
Installing the EverVolt modules with
clamps and rails has been found to
comply with UL 61730 requirements
for downward pressure, e.g., snow, of
up to 7000 Pa (4666 Pa design load*)
and upward pressure, e.g., wind, of
up to 4000 Pa (2666 Pa design load*)
according to the following instructions
(*design loads apply a safety factor of
1.5 to the stated test load, e.g., test
load 7000 Pa / 1.5 = 4666 Pa design
load).
must be carried out according to
the manufacturer’s instructions,
including specific hardware and torque
requirements. Ensure the clamps used
are suitable for the planned installation
and expected system design loads.
•
•
•
The grip area must not extend onto
the module glass and/or cause cell
shading.
Avoid the application of excessive
pressure to prevent frame
deformation.
The module must be secured, e.g.,
clamped, at least once in each
of the four marked zones shown
below (Figure. 8).
When installing on mounting rails,
ensure they run underneath the
module and provide support to the
frame. The positioning of the rail must
ensure that the minimum clamp grip
length and the central point of the
fixation, e.g., the bolt, is fully within the
required clamping zone as indicated on
the following pages.
EverVolt modules must be secured
with a torque between 8.8-18.4 ftlb (12 - 25 Nm). Clamp installation

without affecting the warranty. Loads marked with a * were not certified as part of UL 61730 testing; these have been
evaluated by internal testing process.
**Gap between the uppermost part of the installation surface(e.g. rooftop) and the lowest part of the panel (i.e. underside of panel frame)
CAUTION
The center point of each clamp and the minimum grip length must be fully located in the same clamping zones to be rated

General Installation Manual
ARRAY WIRING
• The term “array” is used to
describe the assembly of several
modules on a support structure
with associated wiring.
• 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. In particular, as the
temperature characteristic of
the PV module, the voltage value
rises on the low temperature side.
Consider the lowest temperature
in the area where the system is
installed and select the equipment
so that it does not exceed the rated
voltage of the equipment.
• Use copper wire which is insulated
to withstand the maximum possible
system open circuit voltage. For
applications where wire conduits
are used, follow the applicable
codes for outdoor installation
of wires in conduits. Minimum
diameter of wire conduit is 4
mm2. The temperature rating
of conductor is -40ºF(-40ºC) to
194ºF(90ºC).
• In order to avoid submerging
cables and connectors in the water,
cables must be fixed either to the
module frame using cable fixing
holes or to the mounting structure.
Also, if the cable is not secured, a
force may be applied to the cable
from the outside, and the module
may be damaged.
• Do not insert PV cable between
back side and mounting structure
rail. When snow weight is applied
to the module, load may be applied
to the cable.
• Verify that all fittings are properly
installed to protect cables against
damage and prevent moisture
intrusion.
• Check your local codes for
requirements
20
DRAINAGE HOLES
•
•
•
In each corner of the EverVolt
module frame small drainage
•
holes are spaced 2.2 in (55 mm)
from the corner on long and
short sides (Figure 22). These
allow humidity caused by rain,
condensation, snow melt, cleaning
or any other process to exit the
frame easily and minimize damage.
These holes must not be used for
•
mounting the module, and they
must not be covered by any part of
the mounting structure. To enable
effective drainage and ensure there
is no damage to the module, the
drainage holes must remain fully
open and enable water egress
during and after installation.
The shape and dimensions of the
drainage holes may vary depending
on product and/or frame design.
EARTH GROUND WIRING
•
•
A module with exposed conductive
parts is considered to be in
compliance with UL 61730 only
when it is electrically grounded in
accordance with the instructions
presented below and the
requirements of the National
Electrical Code.
When grounding a module, it
must be done using an electrical
connection from the module frame. •
Local regulations may require
grounding of the modules.
EverVolt modules have a small
round grounding hole positioned
•
near each corner of the module on
both the long side and the short
side, as shown in Figure 22 and
•
can be further identified by the
grounding symbol stamped in the
frame next to it.
Check all applicable requirements
before beginning installation:
- Suitable grounding lugs must be
used: Listed (KDER) ILSCO, GBL4DBT (tin plated) (E34440)
-Grounding cable size should be
between 4 - 14 AWG (2.1 mm² 21.2 mm²)
-Attach grounds to the grounding
holes in the module frames,
-Fix lug to the frame using a star
washer and lock nut, ensuring a
conductive connection
-Follow the grounding device
manufacturer’s installation
instructions to ensure a safe and
conductive connection, including
any supplementary hardware, e.g.,
star washer, and tighten according
to recommended torque.
•
•
•
•
Length of bolt should be carefully
selected in order to avoid
contacting the back-sheet of the
module.
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).
To avoid galvanic corrosion,
galvanized or hot dipped zinc plated
fasteners are preferred, however
stainless steel fastening materials
are equally suitable.
We recommend installing a
lightning rod and SPD (Surge
protection device) to reduce
damage or breakdown to the PV
module caused by lightning.
The support bars across the rear
of EverVolt modules are connected
to the frame via specially designed
grounding clips and do not need to
be individually grounded.
Negative grounding of the modules
is not required for EverVolt module.

MAINTENANCE
•
•
•
•
•
•
•
•
•
•
•
•
In order to maintain the optimum
output of the module, quality and
safety, please conduct periodic
inspection or cleaning.
The need for cleaning will vary
dependent on location, rainfall,
pollution levels and the angle of
installation – the lower the angle of
installation, the more cleaning will
be required.
Module cleaning must always be
carried out when the modules are
cool, e.g., early morning, to avoid
breakage through thermal shock.
Use of high pressure hoses or
cleaners is not permitted as
these may damage the modules,
laminate or cells.
Avoid putting pressure on the
module surface when cleaning or
drying, e.g., leaning, standing or
resting buckets on it.
Use only deionized water free from
grit and physical contaminants,
at ambient temperature and use
a sponge, microfiber cloth or a
soft brush to wipe away the dirt
(rainwater, tap water or diluted
alcohol may also be used as a
secondary solution).
For further cleaning a mild,
biological and biodegradable
washing-up liquid may be used.
If stains require more effort to be
removed, Isopropyl alcohol of a
concentration less than 10% may
be used.
Using a soft rubber squeegee, wipe
the module surface from the top
downwards to remove any residual
water from the module glass.
Take care not to scratch the surface
or introduce foreign elements that
may cause damage to the module.
Always rinse the module with
plenty of water. Modules can be left
to dry in the air or wiped dry with a
clean and soft cloth or chamois.
When cleaning with washing-up
liquid, it is recommended to start
with smallest area and from the
edge of solar modules in order to
check no damage occurs to the
glass.
General Installation Manual
•
•
Never use abrasive detergent,
strong alkaline detergent, strong
acid detergent or a detergent
which forms a protective layer
on the surface of the glass to
clean any part of the module. The
performance of a solar modules
may be reduced. Please be very
careful since the warranty will
not cover the damages caused by
detergents.
When cleaning the PV module,
please do not put detergent
on junction box or connector.
If detergents and chemical
substances adhere, junction box
and connector may be deteriorated
or damaged.
SYSTEM INSPECTION
•
The system should be inspected
regularly to ensure that:
-Fasteners are secure, tight and
free from corrosion
-Electrical connections are secure,
tight, clean and free of corrosion
-The mechanical integrity of the
cables is intact
•
-Bonding points to ground are
tight, secure and free from
corrosion (which could break the
continuity between the modules
and ground).
If you need inspection or
maintenance, it is recommended
to have a licensed authorized
professional carry out the
inspection or maintenance to avoid
the hazards of electric shock or
injury.
RECYCLING
Panasonic makes every effort to
ensure module packaging is kept to a
minimum. The paper and cardboard
packaging can be recycled and the
protective wrapping and module
separating blocks are also recyclable
in many areas. Recycle packaging and
modules according to local guidelines

ANNEX 1: INSTALLATIONS USING
MODULE LEVEL POWER
ELECTRONICS
This section is applicable to EverVolt
modules referred to in this installation
manual.
Module Level Power Electronics
(MLPE) is the name given to the
range of module-level components
that can be installed in PV system
circuits installed on or in buildings to
reduce shock hazard for emergency
responders.
From January 2019, Section 690.12
of the National Electrical Code (NEC)
(in the U.S.A.) requires the modulelevel rapid shutdown of solar systems
(replacing the previous arraylevel
shutdown requirement of NEC 2014).
This means that all conductors within
an array’s in (300 mm) boundary have
to be reduced to 80 V or less within 30
seconds of rapid shutdown initiation.
manufacturer and the instructions
specific for EverVolt modules
given below. Failure to follow the
manufacturer and the EverVolt
instructions may invalidate the
warranty.
in the diagram below (Figure 24):
INSTALLATION
•
•
To avoid damage to the module and
to allow for thermal expansion,
there must be a minimum gap of
0.1 in (2.5 mm) between the MLPE
device and the module backsheet.
The mounting holes in the module
frame must not be used for the
installation of MLPE devices.
The drilling of extra holes in the
frame is not permitted and will
invalidate the module warranty.
-MLPE devices are suitable for use
wherever solar modules are suitable
•
for installation. Observe any limitations
set by the MLPE manufacturer. (e.g.,
minimum mounting gap between
MLPE and rooftop).
CONNECTION
-When attaching an MLPE device to a
•
solar module, it must be secured to the
module frame. Follow MLPE
•
manufacturer instructions to ensure
optimum mounting of MLPE device
and prevent any slippage during
operation.
-MLPE devices may also be attached to
the mounting construction. In such
•
cases, refer to the instructions provided
by the manufacturer.
First ensure the installation of the
MLPE device is secure and safe.
Following the device
manufacturer’s instructions to
connect the cables from the
MLPE device to the solar module
correctly (usually positive to
positive [+ to +] and negative to
negative [- to -]).
Connection to the next module in
the array should be done from the
‘free’ cables.
MLPE devices may be used on EverVolt
modules where desirable or mandatory
