1. DISCLAIMER OF LIABILITY
The installation, handling and use of Trina Solar crystalline modules are beyond company control. Trina Solar does
not assume any responsibility for loss, damage, injury or expense resulting from the improper installation, handling,
use or maintenance.
Trina Solar assumes no responsibility for any infringement of patents or other rights of third parties that may result
from use of the module. No license is granted by implication or under any patent or patent rights.
Specifications included in this manual are subject to change without prior notice.
2. SAFETY PRECAUTIONS
Potentially lethal DC voltages can be generated whenever PV Modules are exposed to a light source, therefore,
avoid contact with electrically active parts and be sure to isolate live circuits before attempting to make or break any
connections.
Only authorized and trained personnel should have access or perform work on the modules or solar system, always
wearing rubber gloves and boots with maximum working voltage not lower than 1000V DC (For TSM-PE05A.**,
PE14A.**, not lower than 1500V DC).
When working on electrical connections, remove all metallic jewelry, use properly insulated tools and wear
appropriate personal protective equipment to reduce the risk of electric shock.
Do NOT stand or step on, damage or scratch the front or backside surfaces of the module.
Broken modules cannot be repaired and contact with any module surface or frame can lead to electrical shock. Do
NOT use a module with broken glass or torn substrate.
Do NOT disassemble the modules or remove any part of the module.
Protect the electrical plug contacts against corrosion and soiling. Make sure that all connectors are corrosion free and
clean before making the connection.
Do NOT install or handle modules when they are wet or during periods of high wind.
Ensure that all connections are securely made with no gap between the contacts. Any gap can result in electrical
arcing that can cause a fire hazard and/or an electric shock.
Make sure that the polarity of each module or a string is not reversed considering the rest of the modules or strings.
Do NOT artificially concentrate sunlight on these solar modules.
The maximum voltage of Trina Solar modules should not exceed 1000V DC (For TSM-PE05A.**, PE14A.**,
below 1500V DC). This maximum voltage should not be exceeded at any time and, as the voltage of the module
increases, above data sheet values, at operating temperatures below 25°C, then these need to be taken into account
when designing a PV system.
Do NOT use water to extinguish fires of an electrical origin.
Maximum system voltage must not exceed 1000V DC when UL 1000V products (TSM-****D*. **) are used.
Maximum system voltage must not exceed 1500V DC when UL 1500V products (TSM-****E*. **) are used.
Do not walk on the modules.
Do not disconnect the modules under load to avoid arcs and electrical shocks. If needed cover the module surface
with an opaque cover.
Most of the time, the solar module is likely to produce more power, or current, than that rated at standard test
conditions. Accordingly, the value of ISC marked on this module should be multiplied by a factor of 1.25 when
determining the conductor current ratings, fuse sizes and size of controls connected to the PV output. Refer to
Section 690.8 of the National Electric Code to check when an additional multiplying factor of 1.25 may be
applicable.
Installation in Canada shall be in accordance with CSA C22.1, Safety Standard for Electrical Installations, and
Canadian Electrical Code Part 1.The System Fire Class Rating of the module or panel in a mounting system in
combination with a roof covering complete with requirements to achieve the specified System Fire Class Rating for
a non-BIPV module or panel.
Any module or panel mounting system has limitations on specific inclination required to maintain a specific System
Fire Class Rating.
Where common grounding hardware (nuts, bolts, star washers, spilt-ring lock washers, flat washers and the like) is
used to attach a listed grounding/bonding device, the attachment must be made in conformance with the grounding
device manufacturer's instructions.
Common hardware items such as nuts, bolts, star washers, lock washers and the like have not been evaluated for
electrical conductivity or for use as grounding devices and should be used only for maintaining mechanical
connections and holding electrical grounding devices in the proper position for electrical conductivity. Such devices,
where supplied with the module and evaluated through the requirements in UL1703, may be used for grounding

- 4 -
connections in accordance with the instructions provided with the module.
Rated electrical characteristics are within ± 10 percent of measured values at Standard Test Conditions of 1000
W/m², 25°C cell temperature and AM 1.5 solar spectral irradiance.
The fire rating of a Trina Solar PV module is valid only when mounted in the manner specified in the mechanical
mounting instructions of this installation manual.
The module is considered to be in compliance with UL1703 only when the module is mounted in the manner
specified by the mounting instructions below.
A module with exposed conductive parts is considered to be in compliance with UL1703 only when it is electrically
grounded in accordance with the instructions presented below and the requirements of the National Electrical Code
for UL listed products only.
Any module without a frame (laminate) shall not be considered in compliance with the requirements of UL1703
unless the module is mounted with hardware that has been tested and evaluated with the module under this standard
or via a field inspection certifying that the installed module complies with the requirements of UL1703.
The Type 1 and/or Type 2 modules with the specified constructions in the table below, when installed with a UL
listed mounting system that has been rated as a Class A System, is suitable to maintain the System Class A Fire

3. UNPACKING AND STORAGE
At time of receipt, verify that the product delivered is in fact the product ordered. The product name, subname, and
serial number of each laminate are clearly marked on the outside of each packing box.
Leave the product in its original packing box until you are ready to install.
Store packing boxes in a clean, dry area with relative humidity below 85% and ambient temperatures between -20°C
and 50° C .
Do NOT stack more than the maximum amount of allowable pallets on top of each other.
At the installation site, take care to keep modules and particular their electrical contacts clean and dry before
installation. If connector cables are left in damp conditions then the contacts may corrode. Any module with
corroded contacts should not be used.
If pallets are stored temporarily outside then place a protective covering over the pallet to protect it from direct
weathering and do not stack more than 1 pallet high.
Two people are required to unpack the modules from the packing box, when handling modules always use both
hands.
Protect the module edges for temporary storage outside the pallet.
Do NOT use a knife to cut the zip-ties, use wire cutting pliers for safety.
Do NOT place modules directly on top of each other.
PRODUCT IDENTIFICATION3.1.
Each individual module has a unique serial number laminated behind the glass and another permanently
attached to the back-sheet of the module on the product sticker. Note all serial numbers used in an installation
for your records.
4. ENVIRONMENTAL CONSIDERATIONS

- 6 -
CLIMATE CONDITIONS4.1.
Trina Solar Crystalline series modules may be installed in the following conditions for more than 25 years. In
addition to the required IEC certification, Trina Solar products have also been tested to verify resistance to
ammonia fumes that may be present around barns sheltering cattle, as well as suitability for installation in humid
(coastal) areas and areas of high sand storms.
Environment
• Ambient temperature: -40°C to 50°C.
• Operating temperature: -40°C to +85°C.
• Storage temperature: -20°C to +50°C.
• Humidity: < 85RH%
• Mechanical Load Pressure*:5400Pa (550 Kg/m²) Max from the front side (snow) & 2400Pa (wind) from the rear
(Except Installation Method C: Mounting with Single-axis Tracking System - 2400Pa (snow) & 2400Pa (wind)
max)
*Notes:
−The modules have been evaluated by UL according to UL1703 for a maximum positive or negative design loading
of 30lbs.ft2.
−The mechanical load bearing is dependent upon the mounting methods used and failure to follow the instructions
of this manual may result in different capabilities to withstand snow and wind loads.
−The system installer must ensure that the installation methods used meet these requirements and any local codes
and regulations.
5. SITE SELECTION
Trina Solar Modules can be mounted in landscape or portrait orientation however the impact of dirt shading the solar
cells can be minimized by orienting the product in landscape.
Solar module is 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 to equator. But always to design based on local
situations to find out the optimum one.
When installing solar modules on a roof always leave a safe working area between the edge of the roof and the
external edge of the solar array.
In 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.
Do not install PV modules in a location where they will be immersed in water or continually exposed to water from
a sprinkler or fountain, etc.
Avoid using a mounting method that will block the drainage holes in the module frame.
When all solar modules(except for smart module)are mounted in the same plane and orientation then all can be
expected to have similar performance throughout the day and can be connected together to the same inverter
channel.
If solar modules (except for smart module) on the same installation are mounted at different angles or orientations
then energy production can normally be optimized by connecting the different orientations to different inverters (or
different MPPT if the inverter has more than one MPPT). Refer to inverter manufacturers for further guidelines.
According to Intertek-conducted IEC 61701:2011, salt mist corrosion testing of photovoltaic (PV), Trina Solar
modules can be safely installed in corrosive salt areas within proximity of the ocean or sulfurous areas.
According to IEC62716:2013 “Ammonia corrosion testing of photovoltaic (PV) modules” and DLG Fokus testing
for ammonia resistance, Trina Solar modules can be safely installed in ammonia-heavy environments, such as farm
houses.
6. MOUNTING INSTRUCTIONS
MOUNTING METHODS6.1.
PV modules can be mounted to the substructure using either corrosion-proof M8 bolts placed through the mounting
holes on the rear of the module or specially designed module clamps.
Regardless of the fixing method the final installation of the modules must ensure that:
A clearance of at least 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.
The minimum distance between two modules is 0.4in.
The mounting method does not block the module drainage holes.

- 7 -
Panels 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.
Note: The drain holes cannot be blocked in any situation during installation or use.
A. Mounting with Bolts
The frame of each module has four (4) φ9*12 mounting holes, ideally placed to optimize the load handling
capability, to secure the modules to supporting structure.
To maximize mounting longevity, Trina Solar strongly recommends the use of corrosion proof (stainless steel)
fixings
Secure the module in each fixing location with an M8 bolt and a flat washer, spring washer and nut as shown in
Figure 1 and tighten to a torque of 140-180lbf.in.

B. Mounting with Clamps
Trina Solar has tested its modules with a number of clamps from different manufacturers and recommends the

use of clamps which have an EPDM or similar insulating washer, fixing bolt of at least M6.
The clamp must overlap the module frame by at least 0.28in but no more than 0.39in.
Use at minimum 4 clamps to fix modules on the mounting rails.
Modules 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, use at least four clamps on each module, two clamps
should be attached on each long sides of the module (for portrait orientation) or each short sides of the module
(for landscape orientation). Depending on local wind and snow loads, additional clamps may be required to
ensure that modules can bear the potential system load.
Applied torque should refer to mechanical design standard according to the bolt customer is using, ex:
M6 ---- 70lbf.in
M8 ---- 140-180lbf.in

If a different bolt similar to M6 is used (e.g. 1/4" bolt), they need to be tightened to a torque of 140lbf.in.
All parts in contact with the frame should use flat stainless steel washers of minimum 0.06in thickness with an
outer diameter of 0.63-0.79in.
The bolt should be made of stainless steel or the other anti-corrosion material.
Mechanical Load Pressure under this method: 2400Pa (snow) max from the front side & 2400Pa (wind) max
from the rear.
GROUNDING6.2.
All module frames and mounting racks must be properly grounded in accordance with appropriate respective
National Electrical Code.
Proper grounding is achieved by bonding the module frame(s) and all metallic structural members together
continuously using a suitable grounding conductor. The grounding conductor or strap may be copper, copper
alloy, or any 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.
Trina Solar modules can be installed with the use of third party listed grounding devices for grounding the
metallic frames of PV modules. The devices have to be installed in accordance with the grounding device
manufacturer’s specified instructions.
Please refer to the “Product Catalogue” link for detailed grounding hole location and size at
www.trinasolar.com
We also recommend using the following methods to ground installation properly:

The grounding bolt is only listed for use with 6-12 AWG bare solid copper wire.
For proper wire binding, machine bolt B should be torqued to 35lbf.in.
MODULE WIRING6.3.
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 0.006in² which are
rated for 1500 V DC, 90°C and are UV resistant. All other cables used to connect the DC system should have a
similar (or better) specification. Trina Solar recommend that all cables are run in appropriate conduits and sited
away from areas prone to water collection.
The maximum voltage of the system must be less than the maximum certified voltage 1000V typically (For
TSM-PE05A.**, PE14A.**, less than 1500V DC) 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)]
Where
NNo 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 ambient temperature
Each module have two standards 90°C sunlight resistant output cables each terminated with plug & play
connectors. The wire type and gauge of the output cables are 1000V (For TSM-PE05A.**, PE14A.** which are
1500V DC) rated PV Wire cable 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 0.038 to 0.076in2.
For field connections, use at least 12AWG copper wires insulated for a minimum of 90°C and sunlight
resistance with insulation designated as PV Wire.
The minimum bending radius cables should be 1.69in.
7. ELECTRICAL CONFIGURATION
Photovoltaic (electric) systems operate automatically and require very little day-to-day supervision. The solar array
generates DC electricity whenever light falls on it similarly the inverter automatically turns ON as soon as there is
sufficient energy from the solar array to efficiently convert this into grid-.
*Caution:
The module is rated to operate at potentially lethal DC voltages which have the potential can cause severe
electrical shock, arcing and fire hazards. Whilst some solar modules, manufactured by Trina Solar, are certified
to operate up to 1000V DC (For TSM-PE05A.**,PE14A.**, to 1500V DC) always check the module label to
Incorrect Routing of cable
Correct Routing of cable

- 13 -
confirm the actual rating of your product before making connections.
It is recommended to use a suitably rated isolator (DC switch) to interrupt the current flow before disconnecting
the connectors.
FUSING7.1.
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 15A 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.
INVERTER SELETION AND COMPATIBILITY7.2.
When installed in systems governed by IEC regulations, Trina Solar modules normally do not need to be
electronically connected to earth and therefore can be operated together with either galvanically isolated (with
transformer) and transformerless inverters.
Potential Induced Degradation (PID) is sometimes observed in PV modules due to a combination of high
humidity, high temperature and high voltage. PID is most likely to cause degradation under the following
conditions:
a) Installations in the warm and humid climates
b) Installation close to a source of continual moisture, such as bodies of water
To reduce the risk of PID, we strongly suggest that modules feature Trina Solar’s Anti-PID technology, which
can be applied to any Trina product. Alternatively, we require the use of an inverter that includes a transformer
as well as proper grounding of the negative DC leg of the PV array.
Choose inverters with isolation transformers in hot and wet areas (such as shores, wetlands), to ensure proper
module function under positive voltage.
8. MAINTENANCE AND CARE
A well designed solar system requires minimal maintenance; however, system performance and reliability can be
improved by taking some simple steps.
Maintenance should be carried out at least once a year by trained personnel, always wearing rubber gloves and boots
with maximum working voltage not lower than 1000V DC (For TSM-PE05A.**,PE14A.**, not lower than 1500V
DC).
Trim any vegetation which may shade the solar array thus impacting performance.
Check that mounting hardware is properly tightened.
Inspect all cables to verify that connections are tight; the cables are protected from direct sunlight and sited away
from areas of water collection.
Check that all string fuses in each non/earthed pole are operating.
It is recommended to check the torque of terminal bolts and the general condition of wiring at least once a year. Also,
check that mounting hardware is properly torqued. Loose connections will result in damage to the array.
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.
The amount of electricity generated by a solar module is proportional to the amount of light falling on it. A module
with shaded cells will produce less energy and therefore it is important to keep modules clean.
Normally rain water is sufficient to keep the modules clean however it is particularly important to ensure that the
solar modules are clean before onset of summer. Products installed at a tilt angle below 10° or which are located in
particularly dusty areas, are installed in landscape orientation or in areas of high pollution or close to large bird
populations will require more regular cleaning.
When cleaning the module use a soft cloth together with a mild detergent and clean water. Take care to avoid severe
thermal shocks which might damage the module by cleaning modules with water which has a similar temperature to
the modules being cleaned.
When cleaning the back surface of the module, take care to avoid penetrating the substrate material. Modules that
are mounted flat (0° tilt angle) should be cleaned more often, as they will not ''self-clean'' as effectively as modules
mounted at a 10° tilt or greater.
The benefit of cleaning dirt and debris from the array is a trade-off between the cost of the cleaning, increased
energy production as a result of this cleaning, and the inevitable re-soiling of the laminates over time once they have

been cleaned.
If you are unsure whether the array or section thereof needs to be cleaned then first select an array string that is
particularly soiled then
Measure & record the inverter feed in current from that string
Clean all modules in the string
Measure the inverter feed in current again and calculate the % improvement from cleaning
If the improvement is less than 5% then it is normally nor worth spending the expense on cleaning
The above verification should only be carried out when the insolation is effectively constant (clear sky, strong
sunshine, no clouds)
The back surface of the module normally does not need to be cleaned but, in the event this is deemed necessary,
avoid the use of any sharp projects that might damage the penetrating the substrate material.
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.
Do not try to open the junction box to change the diodes even if they malfunction.
In a system using a battery, blocking diodes are typically placed between the battery and the PV module output
to prevent battery discharge at night.
Product Replacement:
In the event that a module is damaged (broken glass or scratch on back sheet) and needs to be replaced then
Observe the safety precautions listed earlier in the manual
Wear cut resistant gloves and other personal protective equipment required for the particular installation.
Isolate the impacted array string to prevent current flow before attempting to remove the module.
Disconnect the MC4 connectors of the affected module using the MC4 disconnect tool
Replace the damaged module with a new module of the same type.
Check the open circuit voltage of the array string and verify that this is within 10V of the other strings to be
connected in parallel.
Turn the isolator back on.
