6 FAQs about [Photovoltaic panel cable laying joint specifications]

What is the new cable standard for solar photovoltaic (PV) systems?

The IEC (International Electrotechnical Commission), has recently published a new cable standard for solar photovoltaic (PV) systems. Intended to cover the direct current (d.c.) cables that connect between solar panels and the electrical collection equipment, this is a new publication that is likely to become widely used around the world.

How to choose a 6mm2 cable for a solar PV system?

Voltage loss:△U=（I*L*2）/ (r*S)=（27.3*30*2）/（57*6）≈4.78V；The grid voltage is 230V, So the voltage loss is close to 230*2%=4.6V。 Therefore, 6mm2 cable is the best choice. To avoid considerable voltage losses and avoidable faults within the solar PV system, it is essential to select the correct cable each time.

How long does a solar PV cable last?

The IEC has published a new cable standard for solar photovoltaic (PV) systems. One of the important but controversial tests included in the standard for solar PV cables is the thermal endurance test. This provides evidence that the cable has an expected long life without degradation and as a result the testing can take several months to complete.

How do I choose the right cabling for my PV system?

Based on the interpretation of IEC standards, and considering factors such as safety, bifacial gains, cable carrying capacity, cable loss, and voltage drop, plant owners can determine the appropriate cabling to ensure safe, stable operation across a PV system’s life cycle.

How do I choose a bifacial cable for a PV system?

Choosing cabling options for PV projects, especially bifacial ones, involves considering a number of variables. DC cables are PV system lifelines as they interconnect modules to combiner boxes and inverters. Plant owners must ensure the size of cable is carefully chosen for the current and voltage of the PV system.

What are the different types of PV cables?

In PV systems, we need to consider three types of cables: PV cables, AC cables, and grounding cables. PV cables are usually laid outdoors and need to be protected from moisture, direct sunlight, cold temperatures, and ultraviolet.
