5. ENVIRONMENTAL CONSIDERATIONS AND SITE SELECTION
5.1 CLIMATE CONDITIONS
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
•Operating temperature: -40°C to +85°C
•Storage temperature: -20°C to +50°C
•Humidity: below 85RH%
•Altitude: ≦2000m
•Mechanical Load Pressure*: 5400Pa Max from the front side and 2400Pa from the rear.
*Notes:
-The modules have been evaluated by TUV according to IEC61215-2016 for a maximum positive design
loading of below 3600Pa, and negative design loading 1600Pa, with 1.5 times safety factor
-The system installer must ensure that the installation methods used meet these requirements and any local
codes
and regulations.
5.2 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 installPV modules in a location where they will be immersedin water or continually exposedto water
from a sprinkler or fountain, etc.
•Avoid using a mounting method that will block the drainage holes in the module frame.
•Whenallsolarmodules(exceptforsmartmodule)aremountedinthesameplaneandorientationthenallcan
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.
6. MOUNTING INSTRUCTIONS
6.1 MOUNTING METHODS
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 115mm(4.5in) (recommended) is provided between modules frame and the surfaceof
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 10mm(0.4in).
•The mounting method does not block the module drainage holes.
•Panels are not subjected to static loads exceeding the maximum permissible loads, and are not subject to
excessive forces due to the thermal expansion of the support structures.

Date: 2020.11 Doc No: PS-M-0904 Ver. B Page - 6 - of 16
*NOTE: The drain holes cannot be blocked in any situation during installation or use.
A. Mounting with Bolts
•The frame of each module has 4-φ9*14mm 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 16~20 N.m(140-180lbf.in.).
•All parts in contact with the frame should use flat stainless steel washers of minimum 1.5mm thickness
with an outer diameter of 20-24mm(0.79-0.94in).

B. Mounting with Clamps
•Trina Solar has tested its modules with a number of clamps fromdifferent manufacturers, fixing bolt of at
least M8. The length of clamp ≥40mm(1.57in). thickness ≥3mm(0.12in), recommended material:
aluminum alloy6003 or 6005.
•The clamp must overlap the module frame by at least 7mm (0.28in) but no more than 10mm (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.
•Whenchoosingthistypeofclamp-mountingmethod,useatleastfourclampsoneachmodule,twoclamps
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 load.
•Applied torque should refer to mechanical design standard according to the bolt customer is using, ex:
•M8 ---- 16-20N.m(140-180lbf.in)

C. Mounting with Single-axis Tracking System
•It is a Single-axis Tracking System, the module is fixed on the axis by bolting long frame.
•The frame of each module has 4-φ7*10mm(0.28*0.39in) mounting holes with specific location shown in
Figure 3.
•Secure the module in each fixing location with an M6 bolt, two flat washers, a spring washer and nut as
shown in Figure 3.
•If a different bolt similar to M6 is used, they need to be tightened to a torque of 16N.m.(140lbf.in).
•All parts in contact with the frame should use flat stainless steel washers of minimum 1.5mm thickness
with an outer diameter of 16-20mm (0.63-0.79in.).
•The bolt should be made of stainless steel or the other anti-corrosion material.
•Mechanical Load Pressure under this method: 30lbs.ft2max fromthe front side &30 lbs.ft2max from the
rear according to UL1703.

6.2 GROUNDING
•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 locations and size at
http://www.trinasolar.com/
•Grounding hardware comes in a package that includes the grounding screw, flat washer、star washer
and wire
•Electrical contact is made by penetrating the anodized coating of the aluminum frame, and tightening
the mounting screw (come with the star washer) to the proper torque of 25lbf.in.
•Grounding wire size (6 to 12 AWG solid bare copper) should be selected and installed underneath the
wire binding bolt.
Star washer, flat washer, grounding wire are placed
in turn, then screwed into the grounding hole to bond
the adjacent modules

For proper wire binding, machine bolt B should be torqued to 35lbf.in.
6.3 MODULE WIRING
•All wiringshould beperformed, byqualified installers, inaccordance with the localcodes and regulations.
•Modules can beconnected in series toincreasethe operating voltage byplugging thepositiveplugof one
module into the negative socket of the next. Before connecting modules always ensure that the contacts
are corrosion free, clean and dry.
•Product canbe irreparably damaged if an arraystringis connected in reverse polarityto another. Always
verifythevoltageandpolarityofeachindividualstringbeforemakingaparallelconnection.Ifyoumeasure
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
4mm²(0.006in²)whichareratedfor1500VDC,90°CandareUVresistant.Allothercablesusedtoconnect
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 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)]
Where
N No 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
•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 have two standards 90°Csunlight resistant output cables each terminated with plug & play

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 0.076in2).
•For field connections, use at least 4mm2copper wires insulated for a minimum of 90°C and sunlight
resistance with insulation designated as PV Wire.
•The minimum bending radius cables should be 43mm(1.69in).
6.4 WIRING
Toensurepropersystemoperationthecorrectcableconnectionpolarity(Figures7&8)shouldbeobservedwhen
connecting the modules toeach otheror to a load, suchas inverter,a battery etc. If modules were notconnected
correctly, the bypass diodes could be destroyed. PV modules canbe wired in series to increase voltage. A series
connection is made when thewire fromthepositive terminal of one module is connectedto the negative terminal
of the next module. Figure 7 shows modules connected in series. PV modules can be connected in parallel to
increasecurrent(Figure8). Aparallelconnectionismadewhenthewirefromthepositiveterminalofonemodule
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 Solar’s limited warranty

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
certifiedto operate up to 1500V DC,always checkthe module label to confirm the actual rating ofyour product
before making connections.
•Itisrecommendedtouseasuitablyratedisolator(DCswitch)tointerruptthecurrentflowbeforedisconnecting
the connectors.
7.1 FUSING
•WhenfusesarefittedtheyshouldberatedforthemaximumDCvoltageandconnectedineach,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.
7.2 INVERTER SELETION AND COMPATIBILITY
•When installed in systems governed by IEC regulations, Trina Solar modules normally do not need to be
electronically connected to earth andthereforecanbe operatedtogether witheither 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 recommend the use of an inverter that includes a
transformer as well as proper grounding of the negative DC leg of the PV array.
•Chooseinverterswithisolationtransformersinhotandwetareas(suchasshores,wetlands),toensureproper
module function under positive voltage.
8. MAINTENANCE AND CARE
•Awelldesignedsolarsystemrequiresminimalmaintenance;however,systemperformanceandreliabilitycan
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 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.
•Itisrecommendedtocheckthetorqueof terminalboltsandthegeneralconditionofwiringatleastonceayear.
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 toavoid
severe thermal shocks which might damage the module by cleaning modules with water which has a similar
temperature to the modules being cleaned.
•When cleaningthe backsurfaceof themodule, takecareto avoidpenetratingthe substratematerial. Modules
that aremounted 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.

•In the event that the solar modules need to be cleaned then clean the module use a soft cloth together with a

after cleaning.
•If you areunsure whether thearray orsectionthereof needs to be cleaned then first select anarray 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 thefront surface ofmodules byan opaque material when repairing. Modules when exposedto 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:

◼Observe the safety precautions listed earlier in the manual
◼Wear cut resistant gloves and other personal protectiveequipment required for the particular installation.
◼Isolate the impacted array string to prevent current flow before attempting to remove the module.
◼Disconnect theconnectors of the affectedmodule usingthe related disconnect tool provided by suppliers.
◼Replace the damaged module with a new module of the same type.
◼Check the open circuit voltage ofthe array string and verify that this is within 10V of the other strings to be
connected in parallel.
◼Turn the isolator back on.
