1、Purpose of this guide
This guide contains information regarding the installation and safe handling of China Sunergy
(Nanjing) Co., Ltd photovoltaic module (hereafter is referred to as “module”). China Sunergy(Nanjing)
Co., Ltd (hereafter is referred to as “CSUN”.)
Installers must read and understand the guide before installation. Any questions, please contact our
customer service department for further explanations. The installer should conform to all safety
precautions in the guide and local codes when installing a module.
Before installing a solar photovoltaic system, installers should become familiar with the mechanical
and electrical requirement for such a system. Keep this guide in a safe place for future reference (care and
maintenance) and in case of sale or disposal of the modules.
⑴General
zInstalling solar photovoltaic systems may require specialized skills and knowledge. Installation
should be performed only by qualified persons.
zEach module comes with a permanently attached junction box. CSUN can provide customers
with fitted cables for ease of installation if desired. Installers should assume the risk of all injury
that might occur during installation, including, without limitation, the risk of electric shock.
zOne individual module may generate DC voltages greater than 30 volts when exposed to direct
sunlight. Contact with a DC voltage of 30V or more is potentially hazardous.
zPhotovoltaic modules are designed for outdoor use. Modules may be ground mounted, mounted
on rooftops, vehicles or boats. Proper design of support structures is responsibility of the system
designers and installers. Use of mounting holes is suggested in a following paragraph.
zDo not attempt to disassemble the modules, and do not remove any attached nameplates or
components from the modules. Do not disconnect under load.

zDo not apply paint or adhesive to module top surface.
zDo not use mirrors or other magnifiers to artificially concentrate sunlight on the modules. Do
not expose backsheet foils directly to sunlight.
zWhen installing the system, abide with all local, regional and national statutory regulations.
Obtain a building permit where necessary.
⑵Safety precaution for installing a solar photovoltaic system
zDo not use modules of different configurations in the same system.
zSolar modules produce electrical energy when light shines on their front surface. The DC
voltage may exceed 30V. If modules series connection, the total voltage is equal to the sum of
the individual module voltages. If modules parallel connection, the total current is equal to the
sum of individual module currents.
zWhen series connection, the maximum total number of series modules shouldn't exceed N. N is
the number of series modules .N= Maximum system voltage /Voc, at standard condition, AM1.5,
temperature 25℃.
zAlso when parallel connection, the maximum total number of parallel modules shouldn't exceed
N. N is the number of parallel modules .N= Conductor current/Isc, at standard condition, AM1.5,
temperature 25℃.
zWe suggest that every series CSUN module string should be fused prior to be connected with
other strings. Please refer to the applicable regional and local codes for additional fuse
requirements. When necessary, please install blocking diodes to protect CSUN module or
CSUN system been damaged by reverse current.
zKeep children well away from the system while transporting and installing mechanical and
electrical components.
zCompletely cover the module with an opaque material during installation to keep electricity
from being generated.

zDo not wear metallic rings, watchbands, ear, nose, lip rings or other metallic devices while
installing or troubleshooting photovoltaic systems.
zUse only insulated tools that are approved for working on electrical installations.
zAbide with the safety regulations for all other components used in the system, including wiring
and cables, connectors, charging regulators, inverters, storage batteries and rechargeable
batteries, etc.
zUse only equipment, connectors, wiring and support frames suitable for a solar electric system.
Always use the same type of module within a particular photovoltaic system.
zThe electrical characteristics are within ±3 percent of the indicated values of Isc, Voc, and Pmax
under standard test conditions (irradiance of 1000W/m2, AM 1.5 spectrums, and a cell
temperature of 25°C (77°F)
zUnder normal outdoor conditions the module will produce current and voltages that are different
than those listed in the date sheet. Data sheet values are values expected at standard test
conditions. Accordingly, during system design, values of short-circuit current and open-circuit
voltage should be multiplied by a factor of 1.25 when determining component voltage ratings,
conductor ampacity, fuse ratings and size of controls connected to the modules or system output.
zFire Resistance rated Class is Class C.
2、Product Identification
Each module has four labels providing the following information:
zNameplate：describes the product type，rated power，rated current，rated voltage，open circuit
voltage，short circuit current，all are measured under STC；weight，dimension，the maximum
system voltage，the maximum fuse rating and power tolerance are all shown on the nameplate.
Generally，power tolerance is ±3%。
zBarcode: each module has a unique serial number. The serial number has 16 digits. The

“CSUN” is the short name for China Sunergy (Nanjing) Co., Ltd. The 5th digit refers to the cell
manufacturer, ABC used to represent. And the 6th digit refers to the modules manufacturer
address, ABC used to represent. The 7th digit refers to the modules production month. ABC
used to represent. For example, “A” refers to “January”；“L” refers to “December”；The 8th
and 9 th digit refer to the modules production workshop. “1” refers to the 1 workshop. The 10th
to 11th digit refer to the modules production year. “10” refers to the year of “2010”. The last
five digits refer to serial number from 00001 to 99999.
There are three barcodes on one module. One is permanently attached to the interior of the module
visible when viewing from the front of the module. This barcode is inserted at the beginning of
laminating. One is attached to the aluminum frame. And another is attached near the nameplate.
zDo not remove the label. If you remove the label, the product warranty will be not guaranteed
by CSUN.
zThe modules would be named only by “CSUN***-**M/P”, They are all identical
products(design, materials, production process, etc ).
3、Mechanical Installation
⑴Selecting the location
zIn most applications, PV modules should be installed in a location where they will receive
maximum sunlight throughout the year. In the Northern Hemisphere, the modules 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 approximately 10 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.
zFor detailed information on the best elevation tilt angle for the installation, refer to standard
solar photovoltaic installation guides or a reputable solar installer or systems integrator.
zThe module should not be shaded at any time of the day.

zAccording to the design of our installation manual, Final customers could adopt the screw
installation method to make the frame supporting.
zPut the modules on the frame and put on the screws and then combine them firmly after put on
all the gaskets. The module frame is made of anodized aluminum, and therefore corrosion can
occur if the module is subject to a salt-water environment with contact to a rack of another type
of metal.(Electrolysis Corrosion) if required. PVC or stainless steel washers can be placed
between the solar module frame and support structure to prevent this corrosion.
zModule support structures that are to be used to support modules should be wind rated and
approved for use by the appropriate local and civil codes prior to installation. Do not use module
near equipment or in locations where flammable gases can be generated or collected.
⑵Selecting the proper support frame
zAlways observe the instructions and safety precautions included with the support frames to be
used with the modules.
zDo not attempt to drill holes in the glass surface or additional mounting holes in the frame. To do
so will void the warranty.
zModules must be securely attached to the mounting structure using four mounting holes for
normal installation. If additional wind or snowloads are anticipated for this installation, additional
mounting holes are also used. The details please see the above drawing. Load calculations are left
to the system designers or installers.
zThe support module mounting structure must be made of durable, corrosion-resistant and
UV-resistant material.
zSelect the height of the mounting system to prevent the lowest edge of the module from being
covered by snow for a long time in winter in areas that experience heavy snowfalls. In addition,

assure the lowest portion of the module is placed high enough so that it is not shaded by plants or
trees or damaged by sand and stone driven by wind.
(3)Roof mount
zWhen installing a module on a roof or building, ensure that it is securely fastened and cannot
fall as a result of wind or snow loads.
zProvide adequate ventilation under a module for cooling (10cm minimum air space between
module and mounting surface).
zWhen installing module on a roof, ensure that the roof construction is suitable. In addition, any
roof penetration required to mount the module must be properly sealed to prevent leaks.
zIn some cases, a special support frame may be necessary.
zThe roof installation of solar modules may affect the fireproofing of the house construction.
zThe modules are rated fire Class C, and are suitable for mounting over a class A roof. Do not
install modules on a roof or building during strong winds in case of accidents.
(4)Pole mount
zWhen installing a module on a pole, choose a pole and module mounting structure that will
withstand anticipated winds for the area.
(5)Grounding

zAll module frames and mounting racks must be properly grounded in accordance with the
appropriate respective national electrical code. Proper grounding is achieved by connecting the
module frame(s) and structural members contiguously one to another using a suitable grounding
conductor. The grounding conductor or strap may be copper, copper alloy, or other material
acceptable for use as an electrical conductor per respective National Electrical Codes. The
grounding conductor must then make a connection to earth using a suitable earth ground
electrode.
zAttach a separate conductor as grounding wire to one of the 6mm diameter grounding holes
marked with the grounding symbol on the module frame with a set of M4 or M5 screw, cup
washer, flat washer, tooth washer, and M4 or M5 nut . This is to ensure positive electrical
contact with the frame.
FIG. Schematic drawing for SST module grounding
(6)General installation
zModule mounting must use the pre-drilled mounting holes in the frame.
zThe most common mounting is achieved by mounting the module using the four symmetry
holes close to the inner side on module frames.
zIf excessive wind or snow loads are expected, all eight mounting holes must be used.

zDo not lift the module by grasping the module’s junction box or electrical leads. Do not stand or
step on module. Do not drop module or allow objects to fall on module. Do not set the module
down on any hard surface.
zTo avoid glass breakage, do not place any heavy objects on the module. Inappropriate transport
and installation may break module.
4、Wiring and connection
zBefore this procedure, please read the operation instructions of the PV control system carefully.
zMake wiring by Multi-connecting cables between the modules in series or parallel connection,
which is determined by user’s configuration requirement for system power, current and voltage.
And please refer to page 4. ⑵Safety precaution for installing a solar photovoltaic system.
zOpen the connection box of the control system and connect the cabled from the PV arrays to the
connection box in accordance with the installation indication of the PV control systems.
zEach module has two 4mm2 diameter type（12AWG）standard 90°C sunlight resistant output
cables each terminated with plug & play connectors. This cable is suitable for applications where
wiring is exposed to the direct rays of the Sun. We recommend that all wiring and electrical
connections comply with the appropriate national electrical code.
zFor field connections, use the minimum Φ4mm2diameter copper wires insulated for a minimum
of 90°C and Sunlight resistant as well.
5、Maintenance and Care
zA built 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 (dependant on site conditions) using a
soft cloth dry or damp, as necessary.
zNever use abrasive material under any circumstances.

zExamine 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.
zCheck fixing screws and mounting brackets and tight, adjust and tighten as necessary.
