l Do not remove any part installed by Jinko Solar or disassemble the module. l All instructions should be read and understood before attempting to install, wire, operate and
maintain the module. l Don’t lift up PV modules using the attached cables or the junction box. l All Dual glass 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. l 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. l Once the PV module has been shipped to the installation site, all of the parts should be unpacked properly with care.
l 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.
l Only PV modules with the same cell size should be connected in series. l 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.
-2-
l During all transportation situations, never drop the module from a vehicle, house or hands. This will damage module.
l Modules (glass, junction boxes, connectors, etc.) shall be protected from long-term exposure to environments containing sulfur, strong acid, strong alkaline, etc., which may pose a risk of corrosion to the product.
l 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 brush paint or corrosive substances on the surface of the modules.
l Do not disconnect any of the modules when under load. l 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. l The junction box connector should not be in contact with oily substances, organic solvents and other corrosive materials to avoid damage to the connector. For example, alcohol, gasoline, lubricants, rust inhibitors, herbicides and so on. l Before the installation of modules, it is recommended to add rainproof facilities in the project site to avoid direct open-air placement. l Corner protection of DV module is used to protect the module during transportation, and the customer can remove or leave it on modules. l Connector of junction box can not be contacted with oily substances, for example, lubricant, rust inhibitor etc. l The maximum altitude the PV module is designed for 2000m. l 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
l Always wear protective head gear, insulating gloves and safety shoes (with rubber soles) and other protective measures during installation.
l When installing or maintaining the photovoltaic system, please do not wear metal rings,
watches and other metal products, so as not to cause electric shock danger and damage the modules. l Keep the PV module packed in the carton until installation. Once the modules are removed from the packing box, they should be installed and connected to the bus box in time. If they are not installed immediately, protective measures (such as adding rubber joint cover, etc.) should be taken on the connection head. l 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. l Do not work in rain, snow or windy conditions. l Due to the risk of electrical shock, do not perform any work if the terminals of the PV module are wet. l Use insulated tools and do not use wet tools. l When installing PV modules, do not drop any objects (e.g., PV modules or tools). l Make sure flammable gasses are not generated or present near the installation site. l Insert module connectors fully and correctly. An audible “click” sound should be heard. This sounds confirms the connectors are fully seated. Check all connections. l 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. l 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. l Do not expose the PV module to excessive loads on the surface of the PV module or twist the frame. l Do not hit or put excessive load on the glass or rear cover, this may break the cells or cause micro cracks. l During the installation or operation, don’t use sharp tools to wipe the rear cover and glass. Scratches can appear on the module. l Do not drill holes in the frame. It may cause corrosion of the frame.
-4-
l 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.
l Modules will have thermal expansion and cold contraction effect. When installing, the interval between two adjacent conventional modules is recommended > 10mm.The minimum clearance between two adjacent double-sided modules is recommended > 20mm;If there are special requirements, please confirm with Jinko and install it;
l During the installation, disassembly, maintenance and any other related processes of the product, it is recommended that the force applied between the cable and the connector, the cable and the junction box be no more than 60N.
2.2 Installation Condition
2.2.1 Climate Condition
Please install the modules in the following conditions: 1The environment temperature: with in 40°C(-40) to 85°C (185) . 2Do 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 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
-5-
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. The PV module can be installed at a distance of 50 m to 500m from the seashore. However, when installing module within the distance, protect the connectors or add dust plugs. After removing the dust plugs, connect the connectors immediately and take other anti-rust measures to prevent rust. When the modules are installed on the roof, they must be separated from the roof by more than 10cm to facilitate air circulation and heat dissipation.
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.
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 gridconnected 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.

2.3.2.3 Fixation with clamps at long sides of frames
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 Kas shown below.

1) All installation methods herein are only for reference, and Jinko solar will not provide related
mounting components, 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.
4) When installing the Dual glass modules at a certain angle, please installed the modules in
front of the sun. But the back which the surface mounting the junction box is not allowed to
exposed to the sun.
2.3.2.4 Fixation with clamps at long sides of frames (Long sides with C, short sides without C)
When installing modules using clamps on the long side of the frame, the mounting place distance of middle of clamp is suggested bigger than J and less than K. the length of clamp is 40mm. The

Table9: Mechanical dimensions for bolt fitting method (NEXTracker)
NoteThe installation method of bolt fitting (NEXTracker) is based on the experimental results in Jinko.
The design of the NexTracker tracking bracket, the selection of accessories and the installation of modules
should be completed by a professional system installer, which can refer to Jinko’s mechanical load.
The load described in this manual is the design load. When calculating the maximum test load, 1.5 times of
safety factor should be considered.
If the design load is greater than 1067Pa (1600Pa test load), consult the support supplier.
* For details, consult with component suppliers and support suppliers.
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 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 4mm2 and the rated current of connectors be more than 10A), otherwise cables and connectors will become overheating for large current. Please pay attention to the
-18-
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 incorrectly
connected to each other, the bypass diodes, cable or junction box maybe damaged.
g) If modules are connected in series, the total voltage is equal to the sum of individual
voltages. The recommended as below,
System voltageN*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 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
-19-
a soft cloth dry or damp, as necessary. Water with high mineral content may leave deposits on the glass surface and is not recommended. It is recommended to use neutral water to clean the glass to avoid strong acid and alkali, 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 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 Dual glass modules of the non-metallic frame should not earthed.
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.
6. Disclaimer of Liability
Because the use of the manual and the conditions or methods of installation, operation, use and maintenance of photovoltaic (PV) product are beyond Jinko’s control, Jinko does not accept any legal responsibility and expressly disclaims liability for any person and property damage arising from the failure to follow the installation, operation, use, maintenance provided in the manual,
