FOR THE WIRING, PAY ATTENTION TO:
• Correct wiring scheme
When designing the system, avoid forming loops (to minimize risk in the event of
an indirect lighting strike). Check that wiring is correct before starting up the
generator. If the measured open circuit voltage (Voc) and short-circuit current (Isc)
dier from the specications, then there is a wiring fault.
• Use of suitable materials
Use cable extensions and plugs that are designed for outdoor applications.
Ensure that they are in perfect electrical and mechanical condition. Use only cables
having one conductor. Select the appropriate cable diameter to minimize voltage
drop (to calculate the minimum cable diameter, the fuse, and to calculate controls,
multiply the Isc and Uoc by a factor of 1.25). Under normal conditions, a photo-
voltaic module is likely to experience conditions that produce more current and/
or voltage than reported at standard test conditions. Accordingly, the values of
Isc and Voc marked on this module should be multiplied by a factor of 1.25 when
determining component voltage ratings, conductor ampacities, fuse sizes, and
size of controls connected to the PV output.
ROOF INSTALLING
•
Use fasteners to fasten the modules to the mounting support structure.
Modules should be bolted to support structures through mounting holes located
in the frame’s back anges only. Stainless-steel bolts, with nuts, washers, and locks
washers, are recommended for module mounting. Creation of additional holes
for mounting is not recommended and will invalidate the warranty.
Modules should not be mounted by supports at the ends.
• Mounting support structure should withstand forces from wind and snowfall
pressure etc. Mounting support structure should use proper materials and
corrosive treatment.
• Installation the modules on the roof should has proper ventilation. A clearance of
4.5 inches (about 115mm) or more behind the modules is recommended to permit
air circulation and cooler module operation.
Elevated temperatures lower operating voltage and power, and shorten module
lifetime. Clearance of 1/4 inch (6.35mm) or more between modules is required to
allow for thermal expansion of the frames.
• The mounting support structure should be re-proof.
• The modules' re safety is class C.
