Modules with different color codes are not recommended to be installed in one block or the same
rooftop.
7.2 INSTALLATION METHOD
7.2.1 MECHANICAL INSTALLATION AND WARNING
The connection of the module to the racking system can be created through the mounting holes,
with clamps, or an embedded system on the frame. The modules must be installed according to
the following examples and recommendations. If a different installation method is desired, please
contact Trina Solar customer service or technical support team for consultation. Improperly
mounted modules maybe damaged. If alternative mounting method is used and not approved by
Trina, the modules will not continue to have a valid warranty.
The minimum distance between two modules is 10mm (0.4in).
Panels must not be subjected to wind or snow loads exceeding the maximum permissible loads,
and must not be subjected to excessive forces due to the thermal expansion of the support
structures.
The module frame drain holes cannot be blocked in any situation during installation or use.
*Notes :
The design loading of modules have been evaluated by TUV according to IEC61215 with 1.5
times safety factor;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.
The modules depicted are mounted on continuous rails that extend beneath the modules. If
modules are mounted without continuous rails below them, the maximum allowable loading will
be reduced and is subject to review by Trina.
A. Mounting with Bolts(4-φ9*14mm mounting holes)
Modules can be attached using the mounting holes on the back of the module frame, by fixing
the module to the support rails with bolts. The mounting details are shown in the following figures.
The frame of each module has 4-φ9*14mm mounting holes, ideally placed to optimize the load
handling capability, to secure the modules to the supporting structure. Installation holes of 4-
φ9*14 mm are used for routine installation, as shown in Figure 1 ,
To maximize mounting longevity, Trina Solar strongly recommends the use of corrosion proof
(stainless steel) attachment hardware.
Secure the module in each mounting location with an M8 bolt and flat washer, spring washer and
nut and tighten to a torque of 16~20 N.m(140-180lbf.in.).
All parts in contact with the modules should use flat stainless steel washers of minimum 1.5mm
thickness with an outer diameter of 20-24mm (0.79-0.94in).
