1. General Information
1.1 Overview
Thanks for choosing Jinko Solar PV modules. In order to ensure the PV modules are installed correctly,
please read the following installation instructions carefully before modules are installed and used.
Please remember that these products generate electricity and certain safety measures need to be taken to
avoid danger.
Make sure the module array is designed in such a way not to exceed the maximum 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.
1.2 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.
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 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.

-2-
Do not touch live terminals with bare hands. Use insulated tools for electrical connections.
All PV systems must be grounded to earth. 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, conductor current ratings, fuse sizes, and size of controls connected to the PV output.
Once the PVmodule hasbeen shipped to theinstallation site, all of the partsshould 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. Modules with LRF(light reflective film) and without
LRF should not be built in the same array or roof.
Connector of junction box can not be contacted with oily substances, for example, lubricant, rust inhibitor

-3-
etc.
The maximum altitude the PV module is designed for ≤ 2000m.
The maximum irradiance is 1300W/m2for module with transparent rear.
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.
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.
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 back sheet of the module.
Do not touch the junctionbox 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 back sheet, this may break the cells or cause micro
cracks.

-4-
During the installation or operation, don’t use sharp tools to wipe the back sheet 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:
a) Operating temperature: within –40°C(-40℉) to 85°C (185℉)
b) Humidity: < 85RH%
﹡Note: The mechanical load bearing (include wind and snow loads) of the module is 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 approximately10 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. Ingeneral, 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.

-5-
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.
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 tiltedso that
the energy production from the PV modules will be
maximized on an annual basis. Figure1: PV module tilt angle
2.3 Mechanical Installation Introduction
Solar PV modules usually can be mounted by using the following methods: bolts and clamps.
﹡Note:
1) All installation methods herein are only for reference, and Jinko solar will not provide related mounting
modules, the system installer or trained professional personnel must be responsible for the PV system’s
design, installation, and mechanical load calculation and security of the system.
2) Before installation, the following items should be addressed:
a) Visually check the module for any damage. Clean the module if any dirt or residue remains from
shipping .
b) Check if module serial number stickers match.
3) Jinko modules are designed to meet a maximum positive (or downward) pressure of 3600Pa (Only refer
to the mentioned module type in this manual) and negative (or upward) pressure of 1600Pa. This design
load was then tested with a safety factor of 1.5 times. So Jinko modules are tested under a maximum
downward pressure of 5400Pa and upward pressure of 2400Pa. When mounting modules in snow-prone
or high-wind environments, special care should be taken to mount the modules in a manner that provides
sufficient design strength while meeting local code requirements.
2.3.1 Mounting with Bolts
For mounting with bolts, the following modules in tables 1 are applicable.
The frame of each module has 8 mounting holes (Length* Width: 14mm*9mm) used to secure the modules
to support structure. Always use all the eight mounting holes to secure the modules. The module frame must
be attached to a mounting rail using M8 corrosion-proof bolts together with spring washers and flat washers
in eight symmetrical locations on the PV module. The applied torque value should be big enough to fix the
modules steadily. The reference value for M8 bolt is 16~20N*m. As to special support system or special

-6-
installation requirement, please reconfirm with the support’s supplier for the torque value. Please find detailed
mounting information in the below illustration as Figure 2.

2.3.2 Mounting with Clamps
The module clamps should not come into contact with the front glass and must not deform the frame. Be sure
to avoid shadowing effects from the module clamps. The module frame is not to be modified under any
circumstances. When choosing this type of clamp-mounting method, please be sure to use at least four
clamps on each module, two clamps should be attached on each long sides 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 value should be big enough to fix the
modules steadily (Please consult with the clamp or support’s supplier for the specific torque value). Please
find detailed mounting information in the below illustration, the mounting place distance is suggested bigger
than J and less than K. The installation diagram of clamp is shown in figure 5.
Note:
The Movement of the mounting rail and the clamps center line are recommended to be within the black arrow
area.

Table 7: Mechanical dimensions of modules installed with screws/clamps on long and short side of frame
Note：The installation method of screws/clamps on long and short side of frame is based on the experimental
results in Jinko.
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.
b) PV modules connected in series should have similar current, 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, 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

-16-
datasheet. The fuse rating value is also corresponding to the maximum reverse current that a module can
withstand, i.e. 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 fusing.
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 capacitymustsatisfy themaximum short-circuit of thePV 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) All module frames and mounting racks must be properly grounded in accordance with local and national
electrical codes. Attach the equipment grounding conductor to the module frame using the hole and
hardware provided. Note that a stainless steel star washer is used between the ground wire and module
frame (see Figure 10 below).This washer is used to avoid corrosion due to dissimilar metals. Tighten the
screw securely.
Figure 10: The ground mounting Clip of PV modules
f) Follow the requirements of applicable local and national electrical codes.
g) These modules contain factory installed bypass diode .If these modules are incorrectly connected to each
other, the bypass diodes, cable or junction box may be damaged.
h) The cable of the junction box is defined as L, as showed below in Figure 11. For Jinko standard full module
L is 900/1200mm, the half–cut module L is 145/290mm, and the SWAN bifacial module L is 150/250mm.
For customized module, L can be based on your condition. Please take the cable length into consideration
before designing the wiring layout.

Figure 11 (2): The half–cut module/SWAN bifacial module junction box
i) It is recommend to use negatively grounded inverters to avoid the PID effect for non-PID free modules.
j) If modules are connected in series, the total voltage is equal to the sum of individual voltages. The
recommended as below,
System voltage≥N*Voc[1+TCVoc* (Tmin-25)]
Where
N module numbers in series
Voc Open circuit voltage (refer to product label or data sheet)
TCVoc Temperature coefficient of open circuit voltage (refer to product label or data sheet)
Tmin Minimum ambient temperature
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.
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
back sheet. Check the back sheet for damage.
f) Check whether the back sheet is burn out.
g) Check if screws and mounting brackets are tight, adjust and tighten as necessary.

-18-
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 asoft 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.
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 rated value in uncertainty condition.
The corresponding electrical specifications can be downloaded from website.
