8. MOUNTING AND NOTES
Systems should be installed by qualified personnel only. It involves electricity, and can be dangerous if the personnel
are not familiar with the appropriate safety procedures.
The Module frame is made of anodized aluminum, and therefore corrosion can occur if the Module is subject to a
salt water environment with contact to a rack of another type of metal (Electrolysis Corrosion). If required, PVC or
stainless steel washers can be placed between the SPV Module frame and support structure to prevent this type of
corrosion. Module support structures that are to be used to support SPV Modules at correct tilt angles should be wind
and snow load rated for use by the appropriate local and civil codes prior to installation.
CNPV SPV Modules can be mounted as following method:
Figure 2 Mounting Method a and b
a)
Using corrosion-proof screws (M8) on the existing installing holes (see drawing 1, 3, 5 & 7) in the Module
frame. The frame of each Module has 4 or 8 mounting holes (12mm×9mm) used to secure the Modules to
supporting structure. The Module frame must be attached to a supporting rack using M8 stainless steel hardware
together with spring washers and flat washers in four places symmetrical on the SPV Module. See method a of
figure 2. The applied torque is about 8 Newton-meters.
b)
Using suitable Module clamps on the Module frame, see method b of figure 2. The module frame must be
attached to supporting rack using M8 stainless steel hardware together with corrosion-proof clips in four places
on the SPV module. See drawing 10, 12, 14 & 16,
with clamping clip,
for positioning of clamping clips. The
applied torque is about 8 Newton-meters. See figure 3 if clamping mounting is on short frames of the module.
