6.4 MOUNTING METHOD
:
SINGLE-AXIS TRACKER
The following mounting methods are only recommended
for double glass modules.
The bolts and clamps used in this section should follow the
requirements described in 6.1 and 6.2.
Under any conditions the junction box should not come in
contact with the subjacent racking structure except for the
torque tube under high loading. For any single axis tracker
installation configured with one module in portrait rows,
bearing houses cannot be located under the module
junction boxes.
If any racking structures, especially bearing house, must be
located under the modules, any racking structure shall not
be higher than frame C side.
If your tracker design cannot meet the above distance
requirement, please contact Canadian Solar technical
support department in writing for advice.
Tracker 1P Bolting method
Install and tighten the module clamps to the mounting rails
using the torque stated by the mounting hardware
manufacturer. M6 X 1 (1/4”) or M8 X 1.25 (5/16”) bolt and
nut are used for this bolting method.
The tightening torques should be 6~9 Nm (4.5~6.6 ft-lbs)
M6 X 1 (1/4”) coarse thread bolts for 10 X 7 mounting hole,
depending on bolt class. M8 X 1.25 (5/16”) for 14 X 9
mounting hole.
