5) Each aluminum clamp is equipped with a M8 bolt, a plain washer, a spring washer and a M8
nut, to fasten the module:
a) Place the module on the two supporting bars (not provided). The bars should be made with
stainless material and treated with an anti-corrosion process (e.g., anodic oxidation
treatment) or aluminum profile.
Each solar PV module needs at least four clamps to fix. Do
not make the clamp contact the glass directly or make the aluminum frame deformation in
the installation process, and avoid the shadow of solar PV components.
b) The bar’s top surface contacted with module frame should come with grooves compatible
with an M8 bolt.
c) If the bars do not come with grooves, holes of a suitable diameter may need to be drilled to
allow bolts to be attached to the bars at the same locations as mentioned above.
d) Secure each clamp by attaching plain washer, spring washer, and nut, in that order.
e) Both of close-ups of Figure 8, indicating the middle clamps and Figure 9, indicating the side
clamps for reference. Suggest the dimensions for middle clamps are:
a
≥
40 mm,
b
≥
26 mm,
c
= 8 mm,
d
≥ 28 mm, and
Ø
= 9 mm. The torque for tightening the nut and bolts are
recommended 17~23Nm when the property class of bolts and screws is Class 8.8.

f) For figure 6 mounting method, the modules must be supported along the length of the edge,
and should overlap the array rail by 10mm – 14mm, as shown in figure 10.
