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.
-2-
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.
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 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.
-3-
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 etc.
The maximum altitude the PV module is designed for ≤ 2000m.
The maximum irradiance is 1300W/m2 for 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
-4-
done in a way to avoid the connector from scratching or impacting the back sheet 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 back sheet, this may break the cells or cause micro
cracks.
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
-5-
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.
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.
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
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
-6-
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 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&3&4.

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.
As shown in the figure on the right, the minimum length L of the
-13-
clamps is 50mm.
