• 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, but use wire cutting pliers.
• Do NOT place modules directly on top of each other.

PRODUCT IDENTIFICATION

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 in an installation for your future
records.

• 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.

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 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.

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 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 COMPATIBILITY

• 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 recommend 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.

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.
• In the event that the solar modules need to be cleaned then clean 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.
• On large systems, 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 time for the re-soiling of the modules after cleaning.
• 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 connectors of the affected module using the related disconnect tool provided by suppliers.
 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.
