• Module can be installed in both landscape and portrait modes.
• The modules must be properly secured to their support so that they can withstand
live load conditions, including wind uplift, to the pressure they have been certied for.
It is the installer's responsibility to ensure that the clamps used to secure the modules
are strong enough.
* The minimum recommended length for each clamp is 50 mm.
General Installation
• Before installing modules check for any optical deviations. Any optical deviations
noticed after system installed may void warranty. Any potential costs for labor, material
or other cost such as documentation, safety or performing the (de/ re-) installation will
not be covered.
• The module mounting structure must be made of durable, corrosion-resistant and
UV-resistant material. Always use a tested and certied mounting structure approved
for your system design.
• In regions with heavy snowfall in winter, select the height of the mounting system
so that the lowest edge of the module is not covered by snow for any length of time. In
addition, ensure that the lowest portion of the module is placed high enough so that it
is not shaded by plants, trees or damaged by ground soil moved by or through the air.
• For ground mounting systems, the minimum distance Suntech recommend from
the ground to the bottom of the module is at least 24 inches (60cm).
• Modules must be securely attached to the mounting structure. For Clamping
System installation methods, the recommended maximum compression for each clamp
is 2900 PSI (20 Mpa) in order to avoid potential damages to module frames. Follow the
instruction of the clamping system supplier.
• Provide adequate ventilation under the modules in conformity to your local
regulations. A minimum distance of 10 cm between the roof plane and the frame of the
module is generally recommended.
• Always observe the instructions and safety precautions included with the module
support frames.
No.6
• This installation manual is applicable for all pv system of 500 m or more away from
the coastline. If you need to install your system less than 500m from the coast line
please refer to Near-coast installation manual (www.suntech-power.com) or contact
Suntech's Customer Support department or our regional representatives.
• Do not use modules near equipment or in locations where ammable gases may
be generated or collected.
Selecting the location
• Select a suitable location for installing the modules.
• The modules should face south in northern latitudes and north in southern
latitudes.
• For detailed information on the best installation angle, refer to standard solar
photovoltaic installation guides or consult a reputable solar installer or systems
integrator.
• Modules should not be shaded at any time. If a module is shaded or even partially
shaded, it will fail to perform at ideal conditions and result in lower power output. A
permanent and/or regular shade on the module voids the warranty.
Mechanical Installation
• Before installing modules on a roof, always ensure the roof construction is suitable.
In addition, any roof penetration required to mount the module must be properly
sealed to prevent leaks.
• Dust building up on the surface of the module can impair with the module
performance. The modules shall be installed with a tilt angle no less than 10 degrees,
making it easier for dust to be removed by rain. A flat angle requires more frequent
cleaning.
• Observe and take into account the linear thermal expansion of the module frames
(the recommended minimum distance between two modules is 2 cm).
• Always keep the front and backsheet of the module free from foreign objects,
plants and vegetation, structural elements, which could come into contact with the
module, especially when the module is under mechanical load.
• When installing a module on a pole, select a pole and module mounting structure
that will withstand the anticipated wind load and snow load for the area.
• Ensure modules are not subjected to wind or snow loads exceeding the maximum
permissible loads, and are not subject to excessive forces due to the thermal expansion
of the support structures. Never allow modules overlap or exceeds the rooftop: Refer to
the following installation methods for more detailed information.

Electrical Installation
General installation
• Any hardware used must be compatible with any other used material to avoid
galvanic corrosion. Defects caused by corrosions void the warranty.
• It is not recommended to use modules with dierent congurations (grounding,
wiring) in the same system.
• Excessive cables must be organized or xed in an adequate way, e.g. attached to
the mounting structure by using non-metallic cable ties. Solar cables, connectors and
juction boxes should not be exposed to water exposure, and snow, and rain or water
submersion for a long period of time(IP65/67).
• For applications requiring high operating voltage several modules can be
connected in series to form a string of modules; the system voltage is then equal to the
sum of the voltage of each module.
• For applications requiring high operating currents several strings of modules can
be connected in parallel; the system current is then equal to the sum of the current of
each string of modules.
• The maximum system voltage is 600 volts or 1000 volts depending on the product
family DC according to standards.
• The maximum number of series connected modules depends on system design,
the type of inverter used and environmental conditions.
• Based on the maximum series fuse rating of module and local electrical installation
code, always make sure Suntech PV modules with more than two strings in parallel for
connection are assembled with the appropriate string fuse for circuit protection.
• There is no limitation on the number of modules that can be connected in parallel,
the number of modules is determined by system design parameters such as current or
power output.
• To prevent the cables and the connectors from overheating, the cross section of
the cables and the capacity of the connectors must be selected to suit the maximum
system short circuit current. The recommended cable is PV wire with a cross section of
at least 4mm2.
• Caution: do not metalize the cables too tight. Any cable damage caused by cable
management system is not covered under Suntech's warranty.
• Always refer to the cable manufacturer's bending radius which includes the radius
just behind the connectors.

• Please refer to local regulations to determine the system wires size, type and
temperature.
• Suntech modules are supplied with connectors used for system electrical
connections. The recommended connectors are H&S RadoxTM connectors, Amphenol
H4, Multi Contact MC4. Suntech strongly recommends using the genuine connector
type specified by Suntech's product data sheet. Any choice of a different connector
type other than specied may void the warranty of the module.
• To ensure reliable electric connection and to prevent possible intrusion of
humidity, H&S RadoxTM integrated twist locking connectors have to be fully mated
together and then manually twisted clockwise ( a turn of around 90 shall be performed
until the gap between the 2 connectors is closed), while two Amphenol H4 or two Multi
Contact MC4 connectors must be mated and locked together until a click can be heard.
• Long-term exposure to wet environments may cause connectors' poor connectivity,
resulting in current leakage and poor conductivity which voids the warranty. Suntech
recommends proper connector/cable/wire management to prevent moisture intrusion.
Depending on the amount of humidity, Suntech recommends periodic inspections of
the installation system to maintain optimal module performance.
• The DC current generated by photovoltaic systems can be converted into AC
and fed into a public Grid. As local utilities’ policies on connecting renewable energy
systems to the Grids vary from region to region. Always seek the advice from a qualied
system designer or integrator. Building permits, inspections and approvals by the local
utility are generally required.
• Especially for larger installations Suntech recommends lightning protection
following the local requirements and regulations.
• When the installation is finished and after connection to the grid please do a
professional hand over to the owner including an installation protocol is required.
Provide a clear documentation of the system to the owner consisting of following
minimum data such as: user guide, system layout, data sheets, performance
expectations, electrical system data e.g. a copy of the installation test report following
minimum requirements of IEC 62446 / IEC 60364-6.
Grounding
• For grounding and bonding requirements, please refer to regional and national
safety and electricity standards. If grounding is required, use a recommended
connector type for the grounding wire.
• For grounding, this guide refers to module frame grounding. If grounding is
required, make sure module frames (metal exposed to touch) are always grounded.
• Suntech recommends always refer to local state and national code requirements
for PV module grounding. Suntech highly recommends negative grounding if it's

To ensure optimum module performance, Suntech recommends the following
maintenance measures:
• Clean the module minimum once a year or more often when required depending
of the pollution. Remove all organic from the surface. Module with soiling or
contamination may reduce the power generation of the system. Always use clean
water and a soft non-abrasive sponge or cloth for cleaning. A mild, non-abrasive
cleaning agent may be used to remove stubborn dirt.
• Uncontrolled pollution is voiding the warranty or not cleaning the modules in time
voids the warranty.
• Check the electrical, grounding and mechanical connections every six months to
verify that they are clean, secure,undamaged and free of corrosion. Or else the warranty
may be voided.
• In the event of a ground fault condition, NEVER wash or spray modules with water
until ground fault has been identied, corrected by an authorized solar inverter service
technician and the inverter is fully operational. This can cause electrocution or a serious
safety issue.
• If any problem arises, consult a professional solar service providers for suggestions.
• Caution: observe solar manufacturers' maintenance instructions for all components
used in the system, such as support frames, charging regulators, inverters, batteries etc.
