6.2.1. Mounting with Bolts
The frame of each module has 4-
φ9*14mm mounting holes, ideally placed to optimize the load
handling capability, to secure the modules to supporting structure.
To maximize mounting longevity, Trina Solar strongly recommends the use of corrosion proof
(stainless steel) fixings
Secure the module in each fixing location with an M8 bolt and a flat washer, spring washer and nut as
shown in Figure 1 and tighten to a torque of 16~20 N.m(140-180lbf.in.).
All parts in contact with the frame should use flat stainless steel washers of minimum 1.8mm thickness
with an outer diameter of 20-24mm(0.79-0.94in).
