1. General Information
1.1 Overview
Thanks for choosing Jinko Solar PV modules (hereafter referred to as
“modules”). In order to ensure that the PV modules are installed correctly,
please read the following instructions carefully before installing and using
the modules. Please remember that PV modules generate electricity and that
certain safety measures must be taken to avoid danger. The protection class of
modules: Class II (IEC61730:2023); (IEC61730:2016). The application class of
modules: Class A (IEC61730:2004). Fire safety class: Class C according to
UL790.
1.2 Warnings
Precautions: Modules generate DC electrical energy when exposed to sunlight or
other light sources. Improper
contact with live parts of the module such as terminals can result in burns,
sparks, and lethal shock. Front glass is used for module protection. Broken
glass can cause electrical safety hazard (may
cause electric shock or fire). These modules cannot be repaired and must be
removed and replaced immediately. Breakage of the rear glass (in the case of
bifacial PV modules) can also lead to the issue of electrical safety. As in
the case of monofacial modules, this cannot be repaired and the modules must
be disconnected and replaced immediately. The table of specifications is
measured under standard test conditions (Irradiance 1000W/m2, module cell
temperature 25oC, air mass=1.5). The current and voltage generated by modules
in different environments are different from those listed in the specification
table. Therefore, when determining the specifications of the rated voltage,
cable capacity, fuse capacity, controller capacity, and other output power
related specifications, take the values of 1.25 times the short-circuit
current and open-circuit voltage marked on the module as reference, and
consult with your inverter/controller supplier for the system configuration
design. During all deliveries, ensure that the modules are not subject to big
shocks during transportation, which may damage the assembly or cause cracks in
the cell of modules. When the electrical load is working, do not disconnect
modules without authorization; if disconnecting the connector is needed, the
DC and AC inverters must be turned off first or the main switch of the
converter must be cut off.
– 3 –
When the battery storage system is connected with the PV system, the battery
must be installed correctly, so as to protect the operation of the system and
ensure the user safety; Follow the battery manufacturer’s instructions for
installation, operation, and maintenance.
Prohibitions: Do not apply excessive force or objects on the surface of the
module, do not impact, and do not twist
the frame of the module, which may damage the cells or cause the cells to
crack. Do not use the module to replace or partly replace roofs and walls of
buildings. Do not remove any part installed by Jinko Solar or disassemble the
module. Don’t lift up the modules using the attached cables or the junction
box. Modules (glass, junction boxes, connectors, etc.) shall be protected from
long-term exposure to
environments containing sulfur, acid, alkaline, etc., which may pose a risk of
corrosion to the product, and organic solvents which can destroy anti-
reflection (AR) coating on the front glass or have a negative impact on the
polymers as junction boxes and backsheets. The junction box must meet IP68
(IEC60529) requirement, however it must be protected from direct sunlight and
water immersion. The interconnection of female-male connectors shall meet the
IP68 (IEC60529) requirements. However, it is not allowed to use the connector
under water for a long time. The junction box and the connector shall not be
in contact with oily substances, organic solvents and other corrosive
materials that may cause functional failure, i.e., alcohol, gasoline,
lubricants, rust inhibitors, herbicides, to avoid damage to the junction box
and the connector. If the junction box and connector are contaminated, they
are forbidden to use. Do not stand or step on the module like shown in the
below pictures. This is prohibited and there is a risk of damaging the module
and injuring the user.
Do not touch live terminals with bare hands. Use insulated tools for
electrical connections. Artificially concentrated sunlight shall not be
directed onto the module. Do not expose the back of the
monofacial module directly to sunlight.
– 4 –
Others: The maximum altitude of module installation is 2000m. The minimum
distance from the seashore is 50m (for more info, please refer to 2.2.2). If
the distance
is less than 50m, we recommend using offshore photovoltaic modules. Please
consult JinkoSolar for details. When looking at PV modules with anti-
reflection (AR) coating technology, it will be normal to see module with a
slight color difference at different angles. Before the installation of
modules, the modules shall be kept under rainproof facility to avoid direct
exposure to rain and sunlight. Meaning of crossed out wheeled dustbin: Do not
dispose of electrical appliances as unsorted municipal waste, use separate
collection facilities. Contact your local government for information regarding
the collection systems available. If electrical appliances are disposed of in
landfills or dumps, hazardous substances can leak into the groundwater and get
into the food chain, damaging your health and well-being. When replacing old
appliances with new ones, the retailer is legally obligated to take back your
old appliance for disposals at least free of charge.
For more, please contact Jinko or refer to the operation and maintenance
guideline.
2. Installation
2.1 Installation Safety
Always wear safety helmet, insulated gloves, insulated rubber shoes, and other
protective measures during installation.
When installing or maintaining the PV system, please do not wear metal rings,
watches and other metal products, so as not to cause electric shock danger and
damage the modules.
Keep the module unpacked until installation. Once the modules are removed from
the pallet, they shall be installed and connected to the inverter. If they are
not installed immediately, protective measures (such as adding rubber joint
cover, etc.) shall be taken on the connection head.
Do not touch the PV module with bare hands during installation unless
necessary. The glass surface
– 5 –
and the frame may be hot. There is a risk of burns and electric shock. Use the
standard safety tools and equipment when installing the modules. 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 module are wet. Use insulated tools
and do not use wet tools. Only the modules of the same size and the
specifications within same range can be connected in series. Connect the male
and female connectors correctly, check the wiring condition, all wires shall
not be detached from the modules, and secure the wires with cable ties so that
the wires do not scratch or squeeze the backsheets of the modules. Do not
touch the junction box or the connectors with bare hands during installation
or under sunlight, regardless if the module is connected to or disconnected
from the system. Do not drill holes in the frame without authorization from
Jinko, which may cause corrosion or other negative effects to the module.
Thermal expansion and cold contraction effect occur on the modules. During
installation, the interval between two adjacent modules must be 10mm. If there
are special requirements, please confirm with Jinko before installation.
During the installation, as for module removal, maintenance and any other
related processes, it is recommended that the force applied between the cable
and the connector, and the cable and the junction box to be no more than 60N.
Do not install the modules anywhere close to open flames or exposed flammable
and explosive gases.
2.2 Installation Condition
2.2.1 Climate Condition
The recommended weather conditions for installing modules are: a) Humidity: <
85% RH b) Ambient air temperature range: -40°C to + 40°C c) Operating
temperature: -40°C to + 70°C
2.2.2 Site Selection
In most applications, Jinko solar PV modules should be installed in a location
where they can 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
– 6 –
degrees away from due South (or due North) will lose approximately 10 to 15
percent of their power output. If the module faces 60 degrees away from due
South (or due North), the power loss will be 20 to 30 percent. Refer to the
longitude and latitude of the location to determine the optimal azimuth of the
module. When choosing a site, avoid trees, buildings or obstructions that
could create shadows on the modules. Shading causes loss of power output, even
though bypass diodes have been installed for the module, shading will affect
the optimum performance and safety issue of the PV modules. Operation in
permanent shading conditions is not recommended. Do not install the PV module
near open flame or flammable materials. 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. JinkoSolar PV modules have passed the IEC
61701 salt spray corrosion test (test method 6). PV modules can be installed
at a distance of 50m away from the seashore. In the case when the modules are
installed within 50m to 500m distance from the seashore, the connectors shall
be protected, i.e., adding dust plugs. After removing the dust plugs, connect
the connectors immediately and take other anti-rust measures to prevent rust.
For roof-top installations, the roof must be covered with at least one layer
of fireproof material suitable for the fireproof class of the PV modules. To
facilitate ventilation and heat dissipation of the module, the minimum
distance between modules and roof must be 10 cm. Walkways should be reserved
for cleaning, repairment and maintenance. For roof-top PV systems, please
follow the safety principles of “from top to bottom” and “from left to right”.
Please use appropriate module components to comply with local laws and
regulations, as well as the building fire safety requirements before
installation, such as fuses, circuit breakers and grounding connectors, etc…
It is possible that modules installed with restricted airflow are not allowed
for use in some hot locations, depending on system design parameters.
Installers should assess if the system design at a specific geographic
location will result in a 98th percentile module operating temperature greater
than 70 °C, and must consider these factors in design of systems.
– 7 –
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 module generates
maximum output power when directly facing the sun.
For standalone systems, the tilt angle of the modules should be selected to optimize the performance
based on the season and sunlight. In general, if the module output is
adequate when the irradiance is low (i.e., winter), the angle chosen
should be adequate during the rest of the year.
For grid-connected systems, modules should be tilted at the angle
that the energy production from the modules will be maximized on
an annual basis. The Fire Class Rating of a module for roof
mounted system shall meet local code requirements in order to
Fig. 1 PV module tilt angle
achieve the specified System Fire Class Rating for a non-BIPV module.
All PV systems have limitations of inclination required to maintain a specific System Fire Class Rating.
2.3 Mechanical Installation
Modules can usually be mounted by using the following methods: fixed
installation-mounting with bolts, fixed installation-mounting with clamps and
tracker installation.
Note: 1) All installation methods herein are only for reference, and they are
based on the test results from
third-party tests and Jinko internal tests; 2) Jinko solar will not provide
related mounting accessories, the system installer or trained professional
personnel must be responsible for the PV system’s design, installation, and
mechanical load calculation and system security; 3) Before installation, the
following items shall be addressed: a) Visually check the module for any
damage. Clean the module if any dirt or residue remains; b) Check if module
serial number stickers match. 4) The maximum loads that different types of
modules can withstand on the front side and back side are dependent on
installation methods, which can be referred to Table 2, Table 3 and Table 5.
If there is heavy snow and strong wind on the module installation site, take
special protection to meet the actual requirements;
Note: Maximum Test Load = 1.5 (Safety factor) x Design load 5) The module must
be mounted on the bracket according to the following installation. If there
are other
– 8 –
installation, please consult JinkoSolar and obtain approval, otherwise the
warranty will be invalid; 6) Under the mounting method of the fixed bracket as
specified in this manual, the modules will be
concave to varying degrees due to the gravity, which is a normal physical
phenomenon and does not affect the normal use and performance of the modules.
Any other external forces will cause additional sinking of the modules, so any
operation of the modules should comply with this manual.
2.3.1 Fixed installation-mounting with bolts Install the module on the rack
using anti-corrosion bolts, elastic washers and flat washers with sufficient
torque to allow the module to be properly secured. The reference value of
tightening torque for M8 bolt is 16-20 NM, and for M6 bolt is 9-12 NM. If
special mounting system or special installation method is required, please
reconfirm with the supplier of the racking system regarding the torque value.
See Figure 2 for detailed installation information.
See Figure 3 for the module models with corresponding installation positions
for bolt installation (using 4 inner holes), Figure 4 for the module models
with corresponding installation positions for bolt installation (using 4 outer
holes) and Table 1 lists different sizes of bolts for different mounting

2.3.2 Fixed installation-mounting with clamps
The clamps must not be installed in contact with the front glass of the module
and must not deform the module frame. Ensure that the clamps do not create a
shadow on the module. Under no circumstances may the frame be altered. When
choosing the mounting method for the clamps, make sure that there are at least
four clamps on each module. The different mounting positions of the clamps
determine the maximum load capacity of the module. Figures 7 – 11 show the
different mounting methods and the positions of the clamps for the different
mounting methods. Depending on the local wind and snow loads, if there is a
possibility of excessive load combinations, additional clamps are required to
ensure that the module has enough load carrying capacity. The torque value
applied during installation of the clamps should be high enough to securely
hold the module (consult installer or bracket supplier for exact torque
value). Clamp dimensions and contact area must follow the values shown in
Table 4. As shown in Fig.5, the length and width of the module are represented
by a and b. The minimum length of a is 50mm, and the minimum width of d that
is the contact width between clamp and frame is 10mm, and minimum thickness of
clamp is 3mm. The distance between the installation position of the long-side
clamp and the edge is represented by L in Fig.7 and Fig.11. The distance
between the installation position of the short-side clamp and the edge is
represented by S in Fig.8 Fig.11.

3. Wiring and Connection
a) When installing and connecting modules, the foam tube must be removed
first, Jinko will not guarantee the safety of products and the consistency of
technical parameters if the connecting heads and tools used are not officially
specified by Jinko or are not installed according to the official
requirements;
b) PV modules connected in series shall have similar current, (please contact
Jinko if there is any concern), and modules must not be connected together to
create a voltage higher than the permitted system voltage. The maximum number
of modules in series depends on system design and the rating of the inverter
used;
c) The maximum fuse rating value in an array string can be found on product
label or product datasheet. The fuse rating value is also corresponding to the
maximum reverse current that a module can
– 17 –
withstand, for example, when one string is in shade then the other parallel
strings of modules will be loaded by the shaded string and the current will
pass through to create a current circuit. Based on the maximum series fuse
rating of module and local electrical codes and standards, make sure the
modules strings in parallel are protected with the appropriate in-line string
fuse; 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 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 module,
it is recommended that the cross-sectional area of cables be 4mm2 and
certified to IEC 62930 type 131), otherwise cables and connectors will become
overheating for large current. Please pay attention that the temperature limit
of cables is 90; e) The module frame must be grounded, and the grounding
design should be in accordance with local national, regional or international
regulations, laws and standards, and the grounding connection should be
carried out by qualified electricians; f) The grounding device must penetrate
the anodic oxide film of the component frame and make full contact with the
interior of the aluminum alloy, and the grounding conductor must be connected
to earth ground through a suitable grounding electrode; g) There are grounding
holes with a diameter of 4mm on the long side of the back frame of the module
by the edge part, the hole can only be used for grounding, cannot be used for
the installation of the module, and the frame of the module shall not be
punched with additional holes; h) Grounding devices and materials shall be
provided by qualified manufacturers. Bolts, nuts and washers shall be of a
size to match the grounding hole and made of stainless steel, and grounding
wires shall be made of copper core wires with a size of AWG 6-12 (4-14mm2) and
shall comply with the requirements of the relevant local national, regional or
international regulations, laws and standards; i) JinkoSolar recommends two
types of grounding: bolted grounding, shown in Figure 11, and clamp grounding.
The bolts should be tightened when grounding is installed and no damage should
be done to the module frame or the grounding wire;
Fig. 11 Grounding of PV modules
– 18 –
j) Follow the requirements of applicable local and national electrical codes.;
k) Modules contain factory-installed bypass diodes. If modules are incorrectly
connected to each other,
the bypass diodes, cables or junction boxes may be damaged; l) The length of
the junction box shall be determined according to the component specifications
and the
customer’s design proposal. As shown in Figure 12 below, consider the length
of the lead wire before designing the wiring;

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 the modules are observed
having slight module color differences at different angles, this is a
normal phenomenon for modules with anti-reflection coating technology. If the
colors are within the cell, please consult Jinko for further analysis; b)
Whether the glass is broken; c) No sharp objects are in contact with the PV
module surfaces; d) The PV modules are not shaded by unwanted obstacles or
foreign material; e) Corrosion along the cells’ busbar. The corrosion is
caused by moisture intrusion thought the module backsheet. Check the backsheet
for damage; f) Check whether the back sheet is burnt; g) Check if screws and
mounting accessories are tight, adjust and tighten as necessary.
4.2 Cleaning
a) A buildup of dust or dirt on the module front face will result in a
decreased energy output. Clean the module preferably once per annum, more
frequently in dusty conditions, using soft cloth dry or damp. Water with high
mineral content may leave deposits on the glass surface and is not
recommended. It is recommended to use neutral water of the PH value ranging
from 6.5 to 8.5 to clean the glass, so as not to cause damage to the glass
coating layer;
b) Never use abrasive material under any circumstances; c) In order to reduce
the potential for electrical and thermal shock, Jinko recommends to clean PV
modules during early morning or late afternoon hours when solar irradiation is
low and the modules are cooler, especially in regions with hot temperatures;
d) Never attempt to clean 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 yield. For
the environment with extreme climate, please contact Jinko after-sales
department for specific requirement if needed; f) For single-side module,
backsheet cleaning is not necessary; for dual-glass module, cleaning the
– 20 –
module backside regularly when necessary, and follow the requirements in 4.2
a) e). Please wear insulated gloves and pay special attention to the cables
and electrical connections during the backside cleaning. 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 modules for signs of deterioration. Check all
wiring for possible rodent damage, weathering and that all connections are
tight and corrosion free. Check the electrical grounding.

5. Electrical Specification
The electrical properties of the components were measured under standard test
condition. In some cases, the component may produce a voltage or current value
higher or lower than the rated value. For specific electrical performance
parameters, refer to the datasheet in the QR code below. (Note: the tolerance
for Voc is ±5%, for Isc is ±5% and for Pmp is ±3%, Maximum System voltage is
1500V DC)
