Figure 8 Installation of rails coincident

The length of supporting bars must be
longer than the length of module frame,
otherwise please confirm with our product
team to get approval.

The above two diagrams show the installation
method using aluminum clamps (also called
fixtures). "D" indicates the allowable installation
range of the aluminum press block. Please refer
to Table 2 for the specific recommended
installation location and corresponding load
("---" indicates that the photovoltaic module
does not apply to the above installation
methods).
•
Each aluminum pressure block is equipped with
an M8 bolt, a flat washer, a spring washer and
an M8 nut. The fixing steps are as follows:
①
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., hot dipped
galvanizing). Each PV module needs at least four
clamps to fix. Do not make the clamp have
contact with the glass directly and do not make
the aluminum frame distort as part of the
installation process. Avoid shadowing of the solar
PV modules, otherwise this may affect the
modules operation or performance.
②
Be sure to avoid shadowing effects from the
module clamps. Weep holes on the module frame
must not be closed or obscured by the clamps.
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 installation of the
components).
③
The bar’s top surface contacted with module
frame should come with grooves compatible with
an M8 bolt.
④
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.
⑤
Secure each clamp by attaching plain washer,
spring washer, and nut, in that order.
⑥
Both close-ups in Figure 10, indicating the middle
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
17~23Nm when the property class of bolts and
screws is Class 8.8.

⑦
For the installation method shown in Figure 8, the
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.
