pieces, 144-cell frame modules NOT more than 16 pieces;
5. SITE SELECTION
Solar modules are recommended to be installed at an optimized tilt angle to maximize the energy
output. It is roughly equal to the latitude of the project site as a rule of thumb, facing toward the
equator. Optimized system designs incorporate other local requirements.
When installing solar modules on a roof, the roof must be covered with a layer of fireproof material
applicable to this class, and adequate ventilation must be ensured between the back sheet and the
installation surface. A safe working area also must be left between the edge of the roof and the
external edge of the solar array
In the case of residential installations on the ground, modules shall be installed following local
regulations, e.g. using fence.
Position the modules to minimize the chances of shading at any time of the day.
Trina Solar recommends that the module should be installed at a working ambient temperature of -
20℃~50℃. The module's limit working ambient temperature range is from -40℃to 85℃. Maximum
altitude less than or equal to 2000m .The maximum mechanical load is 5400 on the front and 2400
on the back.
Try to install modules in a location where there is rare shading throughout the year
If you are planning to use the PV modules where the water damage (Humidity: 85RH%) may be
possible, please consult with Trina local technical support first to determine an appropriate
installation method , or to determine whether the installation is possible.

Date: Nov 18th, 2020 Doc No: PS-M-0694 Ver: G Page 9 of 23
If the module is installed in an area with frequent lightning and thunder, the module must be
protected against lightning strikes. Refer to Trina Solars declaration document for lightning
protection. Please contact with localtechnical support or contact us from
http://www.trinasolar.com/ .
Make sure flammable gases are NOT generated near the installation site.
According to IEC 61701, salt mist corrosion testing of photovoltaic (PV), The module must not
be soaked in the water or in the environment (i.e., fountain, spindrift, etc.) where the module would
touch water (pure water or brine) for a long term. If the modules are placed in an environment of
salt fog (i.e., marine environment) or sulfur (i.e., sulfur sources, volcanoes, etc.), there is a risk
of corrosion. PV Modules certified to IEC 61701 available upon request.
In locations that are 50m ~ 500mm from the ocean, stainless steel or aluminum materials must be
used to contact the PV modules, and the installation position must be processed with anti-corrosion
treatment; refer to the Trina Solar Coastal Application White Paperfor detailed installation
requirements .Please contact with local technical support or contact us from
http://www.trinasolar.com/ .
6. TILT ANGLE
The tilt angle measurement of the PV module refers to measuring the angle between the module
and the horizontal ground surface. For different projects there are different mounting angles. Trina
Solar recommends that the mounting tilt angle should be NOT less than 10, or in accordance with
local regulations or follow the recommendations of experienced PV module installers.
The tilt angle of the PV module is measured between the PV module and a horizontal ground
surface.
In the Northern Hemisphere, the PV modules should typically face south, and in the Southern
Hemisphere, the PV modules should typically face north.
A clearance of at least 115mm (4.5in) (recommended) is provided between modules frame and the
surface of the wall or roof. If other mounting means are employed this may affect the UL Listing or
the fire class ratings.
7. INSTALLATION
7.1 INSTALLATION SAFETY
Trina Solar Modules can be mounted in landscape or portrait orientation (the distance between the
racking and the long side is 150-250mm), and however the impact of dirt shading the solar cells
can be minimized by orienting the product in landscape. Please pay attention that 72-cell/144-cell
framed modules can only be installed in the long side frame on vertical racking not horizontal
racking when customers choose landscape mode, and they cannot be installed in the short frame
side. 60-cell/120-cell framed modules can be installed in both long side frame and short side frame,
but 60-cell/120-cell framed modules cannot installed in the long frame shared with the same
horizontal racking when customers choose landscape mode. Details as shown picture below.

7.2.3 ELECTRICAL INSTALLATION
All wiring should be performed, by qualified installers, in accordance with the local codes and
regulations.
Modules can be connected in series to increase the operating voltage by plugging the positive
plug of one module into the negative socket of the next. Before connecting modules always
ensure that the contacts are corrosion free, clean and dry.
Product can be irreparably damaged if an array string is connected in reverse polarity to
another. Always verify the voltage and polarity of each individual string before making a
parallel connection. If you measure a reversed polarity or a difference of more than 10V
between strings then check the string configuration before making the connection.
Trina Solar modules are provided with stranded copper cables with a cross sectional area of
4mm(0.006in) which are rated for 1500V DC, 90℃and are UV resistant. All other cables
used to connect the DC system should have a similar (or better) specification. Trina Solar
recommends that all cables are run in appropriate conduits and sited away from areas prone
to water collection.
Recommended maximum series/parallel module configurations; ([1000 V/(1.25*Voc)]/[fuse
rating/Isc+1]
Recommended maximum series/parallel module configurations; ([1000 V/(1.25*Voc)]/[fuse
rating/Isc+1]

The maximum voltage of the system must be less than the maximum certified voltage 1500V
typically and the maximum input voltage of the inverter and of the other electrical devices
installed in the system. To ensure that this is the case, the open circuit voltage of the array
string needs to be calculated at the lowest expected ambient temperature for the location.
This can be done using the following formula.
Max System voltage N * Voc * [1 + TCvoc x (Tmin-25)]
N* Voc * [1 + TCvocTmin-25]
Where
N Number of modules in series
Voc Open circuit voltage of each module (refer to product label or data sheet)
TCvoc Thermal coefficient of open circuit voltage for the module (refer to data sheet)
Tmin The lowest expected ambient temperature
When the modules connect in parallel, the output current will be equal to the sum of each
branch current. We suggest that every series SPV 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.
Each module has two standards 90℃sunlight resistant output cables each terminated with
plug & play connectors. The wire type and gauge of the output cables are 1500V rated PV
Wire cables and are 12AWG in size. This cable is suitable for applications where wiring is
exposed to the direct sunlight. We require that all wiring and electrical connections comply
with the appropriate National Electrical Code.
The minimum and maximum outer diameters of the cable are 5 to 7mm (0. 038 to 0.076 in2).
For field connections, use at least 4mm2copper wires insulated for a minimum of 90℃and
sunlight resistance with insulation designated as PV Wire.
The minimum bending radius cables should be 43mm (1.69in).
7.2.3.1 WIRING
To ensure proper system operation the correct cable connection polarity (Figures 1 & 2)
should be observed when connecting the modules to each other or to a load, such as inverter,
a battery etc. If modules were not connected correctly, the bypass diode could be destroyed.
PV modules can be wired in series to increase voltage. A series connection is made when the
wire from the positive terminal of one module is connected to the negative terminal of the next
module. Figure 1 shows modules connected in series. PV modules can be connected in
parallel to increase current (Figure 2). A parallel connection is made when the wire from the
positive terminal of one module is connected to the positive terminal on the next module.
The number of modules in series and in parallel shall be designed reasonably according to
the system configuration.
All instructions above have to be obeyed to maintain Trina Solars limited warranty

7.2.3.2 FUSING
When fuses are fitted they should be rated for the maximum DC voltage and connected in
each, non-grounded pole of the array (i.e. if the system is not grounded then fuses should be
connected in both the positive and negative poles).
The maximum rating of a fuse connected in series with an array string is typically 20A but the
actual module specific rating can be found on the product label and in the product datasheet.
This fuse rating value also corresponds to the maximum reverse current that a module can
withstand (when one string is shaded then the other parallel strings of modules will be loaded
by the shaded string and current will flow) and therefore impacts the number of strings in
parallel.
If a different method is desired, please contact Trina Solar customer service or technical
support team for consultation. Improperly method may damage modules. If alternative method
is used and not approved by Trina, the modules will not continue to have a valid warranty.
8. INVERTER SELECTION AND COMPATIBILITY
Choose inverters with isolation transformers in hot and wet areas (such as shores, wetlands),
to ensure proper module function under positive voltage.
9. MODULE MAINTENANCE FOR PV MODULE
9.1 PANEL VISUAL INSPECTION AND REPLACEMENT
The modules in a PV array should be regularly checked for damage. Factors such as glass
breakage, cable breakage, and junction box damage may lead to function and safety
problems. In the case of a damaged module, replace it with the same type of module. Refer to
the appropriate Product Installation Manual for installation and dis-assembly of module.
It is recommended to perform a preventive inspection every six months without changing the
components of the module. If electrical or mechanical appliances are used for inspection or
maintenance, they should be operated by qualified professionals to avoid any electric shock
or loss of life
Trim any vegetation which may shade the solar array, thus impacting performance.
Check that mounting hardware is properly tightened.
Check that all string fuses in each non/earthed pole are operating.
Replacement modules must be of same type. DO NOT touch live parts of cables and
connectors. Use appropriate safety equipment (insulated tools, insulating gloves, etc.) when
handling modules.
Cover the front surface of modules by an opaque material when repairing. Modules when
exposed to sunlight generate high voltage and are dangerous.
Trina Solar PV modules are equipped with bypass diodes in the junction box. This minimizes
module heating and current losses.
oDO NOT open the junction box to change the diodes even if they malfunction.
oIn a system using a battery, blocking diodes are typically placed between the battery and
the PV module output to prevent battery discharge at night.
In the event that a module is damaged (broken glass or a scratch on back sheet) and needs to
be replaced
oObserve the safety precautions listed earlier in this Manual
oWear cut resistant gloves and other personal protective equipment required for the
particular installation.
