6 FAQs about [Photovoltaic panel string cable laying standards]

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 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 to choose a DC cable for a PV array?

Based on the PV array configuration, the nominal current carrying capacity of the DC cable used in this case should be greater than 602.4A, based on the manufacturer’s datasheet (or according to the cable selection standard IEC60364-5-52, but then the corresponding derating coefficient must also be selected according to the standard.)

Can a single conductor cable be installed in a solar array?

The 2020 and 2017 editions of the NEC have some direction on the support and management of exposed cables. Article 690 of the NEC, Solar Photovoltaic Systems, allows single conductor cable USE-2 and PV Wire to be installed in exposed locations within the array [NEC 690.31(C)(1)].

Why should you choose DC cabling for your solar PV plant?

Among all renewable technologies, solar photovoltaic (PV) power has been dominating the sector for many years. As PV plant owners channel their efforts towards strengthening the performance and efficiency of their operations, DC cabling selection should not be overlooked.
