Modules must be securely attached to the mounting structure using pre-drilled mounting holes in
the frame.
Modules should be bolted to support structures through mounting holes located in the frame's back
flanges only. Do not drill additional holes. Doing so will void the warranty.
Use appropriate corrosion-proof fastening materials. All mounting hardware (bolt/split washer/flat
washer/nut) should be stainless steel M8 size.
Follow mounting guidelines recommended by the PV mounting supplier. The mounting design must
be certified by a registered professional engineer.
The mounting design and procedures shall comply with local codes and all authorities having
jurisdiction.
Use a torque wrench for installation. Tightening torques should be within 10~17 Nm for M8 coarse
thread bolts, depending on bolt quality class.
