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 isto be mounted over a fireresistant roof coveringrated 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.

-2-
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 connections.
Do not use water to extinguish the fire when the power supply is not disconnected.

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 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.
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 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.
Use insulated tools for
electrical connection

-3-
During all transportation situations, never drop the module from a vehicle, house or hands.
This will damage module.
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.
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.
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.
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.
Before the installation of modules, it is recommended to add rainproof facilities in the project
site to avoid direct open-air placement.
Corner protection of DV module is used to protect the module during transportation, and the
customer can remove or leave it on modules.
Connector of junction box can not be contacted with oily substances, for example, lubricant,
rust inhibitor etc.
The maximum altitude the PV module is designed for ≤ 2000m.
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)
and other protective measures during installation.
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.
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.
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 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.

-5-
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.
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;
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:
a) Operating temperature: within –40°C(-40℉) to 85°C (185℉)
b) Humidity: < 85RH%
c) Ambient air temperature range of -40°C to + 40°C
﹡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.

-6-
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.
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 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. The System Fire Class Rating of a module or panel in a roof mounted system

-7-
should meet local code requirements in order to achieve the specified System Fire Class Rating for a
non-BIPV module or panel.
A minimum slope of 22.5°is required for installations in roof mounted systems in order to maintain the fire
class ratings. Any module or panel mounting system have limitations on inclination required to maintain a
specific System Fire Class Rating.

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 six clamps on each modules, and three 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.

2.3.2 The Installation of Dual Glass Modules with Frame.
The frame of each module has 8 mounting holes (Length* Width: 14mm*9mm) used to secure
the modules to support structure. 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
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 and Table 5.

2.3.2.2 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

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.
2.3.2.3 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
applicable product types and installation locations are shown in figure 4 and table 8, the following
types have the same section design.
