SITE SELECTION AND ANGLE
INSTALLATION ENVIRONMENT SELECTION
Trina Solar recommends that the module should be installed in a working environment with an
ambient temperature of -20
℃
to 50
℃
, but not exceed the temperature limit of -40
℃
to 85
℃
.
The modules shall be installed in shadow-free areas throughout the year. Do not install the PV
modules at a place where water damage may occur.
When installing solar modules on the rooftop, a safe working area must be left between the roof edge
and the outer edge of the PV array.
When stacking module on the rooftop, the rooftop should be tested for such loading and the
installation plan must be developed in accordance with the specification requirements.
When using the modules in areas with high wind load and snow load, the supporting structure design
should be carried out in strict accordance with the local design specifications, to ensure that the
external load does not exceed the mechanical strength limit that the modules can withstand.
Salt spray corrosion tests conducted in accordance with IEC 61701 have shown that Trina Solar's
PV modules can be installed near offshore or in the corrosive environment. However, the modules
shall not be immersed in water or in a permanently wet environment (e.g., fountains, spindrift, etc.).
There is a risk of corrosion if the module is placed in a salt spray (i.e., a marine environment) or in
an environment containing sulfur (e.g., volcanoes, etc.).
In the place, 50~500 m away from the sea, stainless steel or aluminum materials need to be used in
where contacting PV modules, and the installation position must be processed with anti-corrosion
treatment. For detailed installation requirements, please refer to the

White Paper,

INCLINATION SELECTION
The tilt angle of the PV module refers to the angle between the module and the horizontal ground.
The tilt angle shall be selected according to the local conditions for different projects. Trina Solar
recommends that the mounting tilt angle should not be less than 10°. For specific tilt angles, it shall
be chosen in accordance with the local design procedures, specifications and regulations, or
following the recommendations of the experienced PV module installers.
The PV modules is highly recommended facing south in the northern hemisphere and north in the
southern hemisphere to get the best performance.
Following the local regulations, if PV modules are installed in North America and any other country
or region comply to UL standard. A minimum of 155 mm (6.10 inch, recommended value) clearance
shall be left between the PV module (backside) and the wall or roof surface. If other installation
methods are used, the PV module's UL certification or fire class rating may get affected.
