• 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.
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.
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%
• Mechanical Load Pressure*: 5400Pa Max from the front side (snow) and 2400Pa from the rear (wind).
(Except Installation Method C: Mounting with Single-axis Tracking System - 2400Pa (snow) and 2400Pa
(wind) max under UL1703 standard)
*NOTE:
• When the project environment meet above temperature, but over 85RH%. Please contact local technical
support and provide project climate information.
• The modules have been evaluated by TUV according to IEC61215 for a maximum positive or negative
design loading of below 5400Pa, by UL according to UL 1703, below 30lbs.ft

.
• 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.
5.2 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 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
