6.3 MOUNTING METHODS FOR FRAMED BIFACIAL MODULE (SINGLE-AXIS TRACKER)
The bolts and clamps used in this section should follow
the requirements in 6.1 and 6.2.
Under any conditions the junction box should not
become in contact with the subjacent racking
structure. If any racking structures, especially bearing
house, have to be located under the modules, the
distance H between the frame and the racking
structure should be at least 40mm.
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”) bolt and nut are used for
this bolting method.
Tightening torques should be 6~9 Nm (4.5~6.6 ft-lbs)
M6 X 1 (1/4”) coarse thread bolts, depending on bolt
class.
