4.3 Installation Methods
4.3.1 Clamping on the frame surface
Modules can be laid across the rails as illustrated in Figure b.
Figure b: clamping method
Remark:
1) The length of rails must be longer than the length of module frame.
2) figure b illustrates the permissible clamping zone for mounting modules on the frame with aluminium
clamps. Please refer to 4.3.3 for the specific recommended installation position and corresponding load.
3) Each clamp is equipped with an M8 bolt, a flat washer, a spring washer and an M8 nut. The fixing steps
are as follows:
a)
Place the module on two rails. The rails 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 contact the glass directly or deform the aluminium frame in
the installation process. Avoid shadowing the PV modules after installation., otherwise may
damage the modules.
b)
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 8 mm, but no more than 11 mm (The clamp section can be changed under the premise
of ensuring the reliable installation of the components).
c)
The rail’s top surface contacted with module frame should com
e with grooves compatible
with an M8 bolt.
