MOUNTING METHODS FOR FRAMED BIFACIAL

MODULE (SINGLE-AXIS TRACKER)

• 

The bolts and clamps used in this section should fol-

low the requirements in 6.1 and 6.2.

• 

Under any conditions the junction box cannot be-

come in contact with the subjacent racking structure. 

If any racking structures, especially bearing house, 

have to be located under the modules, the distance 

H the frame and the racking structure should be at 

least 40mm.

TRACKER 1P BOLTING METHOD

• 

Install and tighten the module clamps to the mount-

ing 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.

• 

If your tracker design cannot meet the above dis-

tance requirement, please contact EDF ENR PWT 

technical support department in writing for advices.
