TUV Solar Cable
Copper conductor core cross-linked polyolefin jacket solar cable
with TUV certification
1. Cables in a Solar PV System
Solar cables and wires are seen as the arteries and veins of any
solar PV system.
Mostly, the electricity generated by PV solar panels is used at
another place. Solar cables and wires are required to transport
2.Solar DC Cables
There are two types of solar DC cables:
‘Module cables’ or‘string cables.’
These cables are usually integrated into the PV solar panels and
are equipped with suitable connectors to be interconnected.
Here, you have little influence on the type of cable used.
DC main cable
Special extension cables should be used to connect the posiive and
negative cables from strings to the generator connection box (or
directly to the solar power inverter).
Depending on the power output of the modules, PV cables with
cross-sectional areas of 2.5mm, 4mm and 6mm are usually employed.
The DC cables are used outdoors. To ensure earth fault and
short-circuit, the positive and the negative cables may not be laid
together in the same cable.
Single-wire cables with double insulation have proven to be a
practical solution and offer high reliability.
The DC cables between the modules as well as between the generator
connection box and solar power inverter are two-core cables, a
current-carrying usually a live red wire, and a negative blue wire,
both are typically surrounded by an insulation layer.
There are three types of designs to connect the PV strings to the
solar power inverter:
Node String system
PV system with DC Combiner Box
3.AC connection cable
The AC connection cable links the solar power inverter to the
electricity grid via the protection equipment.
In the case of three-phase inverters, the connection to the low
voltage grid is made using a five-core AC cables (three live wires
for the three phases that carry the current, a neutral wire carry
current away from the device and ground wire (safety wire) that
connects the casing of the device to the ground).
Systems with single-phase inverters require three-core cables (One
live wire, a neutral wire, and ground wire).
National codes and regulations need to be followed.
