6.4 INSTALL EFFECT CHART
The install effect chart is as follows. Please consult with Trina Solar engineers to confirm whether the rails
match Trina clamp/frame or not. And confirm there are no shelter on the back of the modules.
7. MODULE WIRING
Each module has two 4mm
2
diameter type standard 90°C sunlight resistant output cables each terminated with
plug & play connectors. This cable is suitable for applications where wiring is exposed to the direct rays of the
sun. We recommend that all wiring and electrical connections comply with the appropriate national electrical
code(s).
For field connections, use the minimum 4mm
2
diameter copper wires insulated for a minimum of 90°C and
sunlight resistant as well.
The minimum and maximum outer diameters of the cable are 5mm to 7mm. Refer to
for the maximum electrical rating of series fuse.
8. MODULE TILT ANGLE
Trina Solar PV modules connected in series should be installed at the same orientation and angle. Different
orientation or angle may cause loss of output power because each module may be exposed to different amounts
of solar irradiation.
Trina Solar PV modules produce the most power when they are perpendicular to incoming sunlight. For
installations where the PV modules are attached to a permanent structure, the PV modules should be tilted for
optimum winter performance. The module tilt angle is measured between the solar modules and the ground.
Optimal tilting of PV module is almost the same as the latitude of installation location.
