the glass and should not deform the frame, otherwise
they may cause module damage.
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 have at least 8mm but no more than 11mm
overlap with the frame of the module (The clamp
section can be changed under the premise of
ensuring reliable installation).
③
The top surface of the rail contacted with module
frame should be equipped with grooves compatible
with an M8 bolt.
④
If the grooves are not provided, holes of a suitable
diameter may need to be drilled to allow bolts
attaching to the rail at the same locations as
mentioned above.
⑤
Ensure that the mounting sequence of each clamp is
in the order of flat washer, spring washer and nut.
⑥
There are two types of clamps, the mid clamp shown
in Fig 10 and the fringe clamp shown in Fig 11 and
Fig. 12. The mid clamp has dimensions of a
≥
40 mm, b
≥
26 mm, c
≥
5 mm, d
≥
28 mm, Ø =9
mm. For module of 182mm-wafer, the size of mid
and fringe clamp must meet a
≥
60 mm. The
tightening torque is suggested to be 17~23Nm for
Class 8.8 screw and bolts.

⑦
To prevent modules from coming off the fixed
device after installation, it is suggested to choose
fringe and mid clamps and make contact with the
A side of the frame with groove patterns. Suggest
to have 9 patterns with a space between 2 adjacent
patterns of 1.2mm and a depth of 0.6mm, as shown
in figure 11.
⑧
For the installation method shown in Fig. 9, the
module needs to be fixed with professional clamps
(as shown in Fig. 13), and the overlap between the C
side of the module and the rail should be ≥ 15mm.
Solahart limited warranty will be void if improper
clamps or improper installation is used.
