Use PV rated solar cable for wiring 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.

Secure the cables to the mounting system using UV-resistant cable ties. Protect exposed
cables from damage using suitable precautions. Avoid leaving DC cables in direct and
extended exposure to sunlight.

WIRING AND INSTALLATION GUIDELINES

IRING AND INSTALLATION GUIDELINES
IRING AND INSTALLATION GUIDELINES
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. Keeping the
cells’ operating temperature low will allow for the best possible performance. The
module’s performance will be enhanced.
•
Do not install modules in systemic and ongoing shade; this can cause the temperature
of exposed cells to rise, reducing output, and may stress conductive bonds in module.
•
The DC conductors must be properly gauged so that the voltage drop does not
exceed 2% of the nominal voltage.
•
BenQ Solar PV modules are supplied with or without cables, according to where they
are ordered. If supplied without cables, it is recommended that cables with cross
sections between 4 and 10 mm
2
be used.
•
The cables, which allow easy handling while providing high protection against
overloads and short-circuits. They are made of flexible Cu conductors, cross linked
insulated polyethylene and coated with polyvinyl chloride or similar insulation. The
insulation is flame, acid and alkali resistant and should be stored in an area free of any
corrosive gases.

•
The modules should be handled and installed by qualified persons only.
•
Keep all panel connectors dry and clean at all times. Do not attempt to establish an
electrical connection with wet, soiled, dusty/dirty, or otherwise faulty connectors.
•
Unconnected connectors must be covered/protected at all times to prevent dust,
foreign particles, etc. from accumulating within prior to connection.
•
Do not allow unprotected connectors to rest on the ground or roof surface.
