system voltage of any system component such as connectors or inverters.
The assembly is to be mounted over a fire resistant roof covering rated for the
application. Before mounting the module, please consult your local building
department to determine approved roofing materials.
The modules are qualified for application class A: Hazardous voltage (IEC 61730:
higher than 50V DC; EN 61730: higher than 120V), hazardous power applications
(higher than 240W) where general contact access is anticipated. Modules qualified
for safety through EN IEC 61730-1 and -2 within this application class are considered
to meet the requirements for Safety Class II.
1.3 Warnings
PV modules generate DC electrical energy when exposed to sunlight or other
light sources. Active parts of module such as terminals can result in burns, sparks,
and lethal shock.
Artificially concentrated sunlight shall not be directed on the module or panel.

-3-
Front protective glass is utilized on the module. Broken solar module glass is an
electrical safety hazard (may cause electric shock or fire). These modules cannot
be repaired and should be replaced immediately.
To reduce the risk of electrical shocks or burns, modules may be covered with an
opaque material during installation to avoid injury.
The installation work of the PV array can only be done under the protection of
sun-sheltering covers or sunshades and only qualified person can install or
perform maintenance work on this module.
Follow the battery manufacture‘s recommendations if batteries are used with
modules.
Do not use this module to replace or partly replace roofs and walls of living
buildings.
Do not install modules where flammable gas may be present.
Do not touch live terminals with bare hands. Use insulated tools for electrical

Do not remove any part installed by Jinko Solar or disassemble the module.
All instructions should be read and understood before attempting to install, wire,
operate and maintain the module.
Don’t lift up PV modules using the attached cables or the junction box.
All Eagle Dual PV systems except the non-metallic frame must be earthed. If
there is no special regulation, please follow the National Electrical Code or other
national code.
Under normal conditions, a photovoltaic module is likely to experience conditions
that produce more current and/or voltage than reported at standard test
conditions. Accordingly, the value of Isc and Voc marked on the module should
be multiplied by 1.25 when determining PV system component voltage ratings,
Use insulated tools for

conductor current ratings, fuse sizes, and size of controls connected to the PV
output.
Once the PV module has been shipped to the installation site, all of the parts
should be unpacked properly with care.
Do not stand or step on the PV module like below pictures show. This is
prohibited and there is a risk of damage to the module and cause injury for you.
Only PV modules with the same cell size should be connected in series.
During transporting modules, please attempt to minimize shock or vibration to the
module, as this may damage the module or lead to cell micro cracks.
During all transportation situations, never drop the module from a vehicle, house
or hands. This will damage module.
Do not clean the glass with chemicals. Only use tap water. Make sure the module
surface temperature is cool to the touch. Cleaning modules with cool water when
module surface temp is high may result in glass breakage.
Do not disconnect any of the modules when under load.
When looking at PV modules with anti-reflection (AR) coating technology, it will
be normal to see some cells with a slight color difference at different angles.
2. Installation
2.1 Installation safety
Always wear protective head gear, insulating gloves and safety shoes (with
rubber soles).
Keep the PV module packed in the carton until installation.
Do not touch the PV module unnecessarily during installation. The glass surface
and the frame may be hot. There is a risk of burns and electric shock.

-5-
Do not work in rain, snow or windy conditions.
Due to the risk of electrical shock, do not perform any work if the terminals of the
PV module are wet.
Use insulated tools and do not use wet tools.
When installing PV modules, do not drop any objects (e.g., PV modules or tools).
Make sure flammable gasses are not generated or present near the installation
site.
Insert module connectors fully and correctly. An audible "click" sound should be
heard. This sounds confirms the connectors are fully seated.Check all
connections.
The module leads should be securely fastened to the module frame, Wire
Management should be done in a way to avoid the connector from scratching or
impacting the rear cover of the module.
Do not touch the junction box and the end of the interconnect cables (connectors)
with bare hands during installation or under sunlight, regardless if the PV module
is connected to or disconnected from the system.
Do not expose the PV module to excessive loads on the surface of the PV
module or twist the frame.
Do not hit or put excessive load on the glass or rear cover, this may break the
cells or cause micro cracks.
During the installation or operation, don’t use sharp tools to wipe the rear cover
and glass. Scratches can appear on the module.
Do not drill holes in the frame. It may cause corrosion of the frame.
When installing modules on roof mounted structures, please try to follow the
“from top to bottom” and/or “from left to right” principle, and don’t step on the
module.This will damage the module and would be dangerous for personal
safety.
2.2 Installation Condition
2.2.1 Climate condition
Please install the modules in the following conditions:
1）The environment temperature: within –40°C(-40℉) to 85°C (185℉) .
2）Do not install modules in a place where there may be water immersion.
﹡Note: The mechanical load bearing (include wind and snow loads) of the module is

-6-
based on the approved mounting methods. The professional system installer must be
responsible for mechanical load calculation according to the system design.
2.2.2 Site selection
In most applications, Jinko solar PV modules should be installed in a location where
they will receive maximum sunlight throughout the year. In the Northern Hemisphere,
the module should typically face south, and in the Southern Hemisphere, the modules
should typically face north. Modules facing 30 degrees away from true South (or
North) will lose approximately 10 to 15 percent of their power output. If the module
faces 60 degrees away from true South (or North), the power loss will be 20 to 30
percent.
When choosing a site, avoid trees, buildings or obstructions, which could cast
shadows on the solar photovoltaic modules especially during the winter months when
the arc of the sun is lowest over the horizon. Shading causes loss of output, even
though the factory fitted bypass diodes of the PV module will minimize any such loss.
Do not install the PV module near open flame or flammable materials.
When solar modules are used to charge batteries, the battery must be installed in a
manner, which will protect the performance of the system and the safety of its users.
Follow the battery manufacturer’s guidelines concerning installation, operation and
maintenance recommendations. In general, the battery (or battery bank) should be
away from the main flow of people and animal traffic. Select a battery site that is
protected from sunlight, rain, snow, debris, and is well ventilated. Most batteries
generate hydrogen gas when charging, which can be explosive. Do not light matches
or create sparks near the battery bank. When a battery is installed outdoors, it should
be placed in an insulated and ventilated battery case specifically designed for the
purpose.
Do not install the PV module in a location where it would be immersed in water or
continually exposed to water from a sprinkler or fountain etc.
2.2.3 Tilt angle selection
The tilt angle of the PV module is measured between the surface of the PV module
and a horizontal ground surface (Figure 1). The PV module generates maximum
output power when it faces the sun directly.

-7-
Figure1: PV module tilt angle
For standalone systems with batteries where the PV modules are attached to a
permanent structure, the tilt angle of the PV modules should be selected to optimize
the performance based on seasonal load and sunlight. In general, if the PV output is
adequate when irradiance is low (e.g., winter), then the angle chosen should be
adequate during the rest of the year. For grid-connected installations where the PV
modules are attached to a permanent structure, PV modules should be tilted so that
the energy production from the PV modules will be maximized on an annual basis.
2.3 Mechanical Installation introduction
Jinko Eagle Dual modules and Jinko Eagle Bifacial Dual modules usually can be
mounted by the clamps.

Be sure to avoid shadowing effects from the module clamps. When choosing this type
of clamp-mounting method, please be sure to use at least four clamps on each
module, and two clamps should be attached on each long side of the module.
Depending on the local wind and snow loads, if excessive pressure load is expected,
additional clamps or support would be required to ensure the module can bear the
load. The applied torque should be large enough to fix it steadily ( about 16-20 N▪m ) .
For safety, you’d better follow the clamps manufacture’s recommendation. Please
find detailed mounting information in the below illustration, and we suggest the
clamps are mounted between J and K,as shown below.

3. Wiring and connection
a) Before this procedure, please read the operation instructions of the PV system
carefully. Make wiring by Multi-connecting cables between the PV modules in
series or parallel connection, which is determined by user’s configuration
requirement for system power, current and voltage.

-11-
b) PV module connected in series should have similar current. Modules must not be
connected together to create a voltage higher than the permitted system voltage
(1500VDC). The maximum number of modules in series depends on system
design, the type of inverter used and environmental conditions.
c) The maximum fuse rating value in an array string can be found on the product
label or in the product datasheet. The fuse rating value is also corresponding to
the maximum reverse current that a module can withstand. Thus based on the
maximum series fuse rating of module and local electrical installation criteria,
make sure the modules strings in parallel for connection need to be assembled
with appropriate string fuse for circuit protection.
d) Open the combiner box of the control system and connect the conductor from the
PV arrays to the combiner box in accordance with the the design and local codes
and standards. The cross-sectional area and cable connector capacity must
satisfy the maximum short-circuit of the PV system (for a single component, we
recommended that the cross-sectional area of cables be 4mm2and the rated
current of connectors be more than 10A), otherwise cables and connectors will
become overheating for large current. Please pay attention to the temperature
limit of cables is 85℃.
e) Follow the requirements of applicable local and national electrical codes.
f) These modules contain factory installed bypass diode .if these modules are in
correctly connected to each other, the bypass diodes, cable or junction box may
be damaged.
4. Maintenance and care
It is required to perform regular inspection and maintenance of the modules,
especially during the warranty period. To ensure optimum module performance, Jinko
recommends the following maintenance measures:
4.1 Visual Inspection
Inspect the modules visually to find if there are any visual defects, If there are, the
following items should be evaluated:
a) If modules are observed having slight cell color differences at different angles,
this is a normal phenomenon of modules with anti-reflection coating technology.
b) Whether the glass is broken;

-12-
c) No sharp objects are in contact with the PV module surfaces
d) PV modules are not shaded by unwanted obstacles and;or foreign material
e) Corrosion along the cells’ bus-bar. The corrosion is caused by moisture intrusion
thought the module rear cover. Check the rear cover for damage.
f) Check whether the rear cover is burn out.
g) Check if screws and mounting brackets are tight, adjust and tighten as
necessary.
4.2 Cleaning
a) A build up of dust or dirt on the module(s) front face will result in a decreased
energy output. Clean the panel(s) preferably once per annum if possible (depend
on site conditions) using a soft cloth dry or damp, as necessary. Water with high
mineral content may leave deposits on the glass surface and is not
recommended.
b) Never use abrasive material under any circumstances.
c) In order to reduce the potential for electrical and thermal shock, Jinko
recommends cleaning PV modules during early morning or late afternoon hours
when solar radiation is low and the modules are cooler, especially in regions with
hotter temperatures.
d) Never attempt to clean a PV module with broken glass or other signs of exposed
wiring, as this presents a shock hazard.
e) Never use chemicals when cleaning modules as this may affect the module
warranty and energy output.
4.3 Inspection of Connector and Cable
It’s recommended to implement the following preventive maintenance every 6
months:
a) Check the sealing gels of the junction box for any damage.
b) Examine the PV module(s) for signs of deterioration. Check all wiring for possible
rodent damage, weathering and that all connections are tight and corrosion free.
Check electrical leakage to ground. The Eagle Dual modules of the non-metallic
frame should not earthed.

-13-
5. Electrical specification
The module electrical rating are measured under Standard Test Conditions, which
are 1000W/m2, irradiance with AM 1.5 spectrum and 25 deg (77°F) ambient
temperature. The module might produce more or less voltage or current than rating
value in uncertainty condition. Accordingly, the values of ISC and VOC marked on this
module should be multiplied by a factor of 1.25 when determining component voltage
ratings, conductor current ratings, fuse sizes, and size of controls connected to the
PV output.
The corresponding electrical specification can be downloaded from website
www.jinkosolar.com.
