The clamp must overlap the module frame by at
least 8mm but no more than 11mm (The clamp
section can be changed under the premise of
ensuring
the
reliable
components).
The bar's top surface contacted with module
③
frame should come with grooves compatible with
an M8 bolt.
If the bars do not come with grooves, holes of a
④
suitable diameter may need to be drilled to allow
bolts to be attached to the bars at the same
locations as mentioned above.
Secure each clamp by attaching plain washer,
⑤
spring washer, and nut, in that order.
Both close-ups in Figure 10, indicating the middle
⑥
clamps and Figure 9, indicating the side clamps
are for reference. Suggested dimensions for
middle clamps are: a ≥ 40 mm, b ≥ 26 mm, c ≥
5 mm, d ≥ 28 mm, and Ø = 9 mm. The torque for
tightening the nut and bolts are recommended

For the installation method shown in Figure 8, the
⑦
modules need to be fixed with professional solar
pressure blocks (as shown in Figure 11), and the
overlap between the C surface of the module and
the guide rail should be ≥15mm. If improper
fixtures or incorrect installation methods are used,
the limited warranty will be invalid.
