Check that the wiring is correct before commissioning the system. If the measured open
circuit voltage differs from the specifications, then there is a wiring fault. Ensure that the
polarity is correct.

Use special solar cable and suitable connectors only. Ensure that they are in perfect
electrical and mechanical condition. Use only single wire cables. Select a suitable
conductor diameter to minimize voltage drop.

We recommend securing the cables to the mounting system using UV-resistant cable
ties. Protect exposed cables from damage using suitable precautions. Avoid direct
exposure to sunlight.
Installation
Please note the following instructions:
To ensure the correct orientation of the module, the module should face southwards in
the northern hemisphere and northwards in the southern hemisphere.
The module must be installed so that air can freely circulate around it. The cells’ working
temperature will thus be reduced and, consequently, the module’s performance will be
enhanced.
The cross section for the conductors must be ensured that the voltage drop during the
installation does not exceed 2% of its nominal voltage.
BenQ Solar PV modules are supplied with or without cables, according to where they
are ordered. Should they be supplied without cables, it is recommended that cables with
cross sections between 4 and 10 mm

be used. The cables, which allowed easy handling
while providing high protection against overloads and short-circuits, are formed by
flexible Cu conductors, cross linked insulated polyethylene and coated with polyvinyl
chloride or similar. They must be kept with low corrosive gas surrounded and with acid
and alkali resistance and must not be flamed nor fire propagated during operating.
The back of the module avoid direct exposure to sunlight.
Warnings
The modules should be installed and handled by qualified persons only.
Do not climb up or walk on the module. Do not drop the module or throw objects onto
it.
Use the module only for the purpose to which it is designed for. Do not dismantle the
module or remove any part, label, or piece installed by the manufacturer and protection
diodes without the manufacturer’s authorization.
Do not concentrate sunlight or other artificial light sources onto the module.
Use tools duly coated with insulating material while working with the modules.
