6 FAQs about [Photovoltaic panel cable laying standard requirements]

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.

What are the requirements for a PV installation?

Virtually all domestic PV installations will fall under the scope of Part P. Part P requires the relevant Building Control department to be notified and approve the work. There are two routes to comply with the requirements of Part P: Notify the relevant Building Control department before starting the work.

Are there any UK standards relating to a PV installation?

While many UK standards apply in general terms, at the time of writing there is still relatively little which specifically relates to a PV installation. However, there are two documents which specifically relate to the installation of these systems that are of particular relevance:

How do I choose a cable for a PV array?

Cables routed behind a PV array must be rated for a minimum temperature of 80 ̊C. Cables must be selected so as to minimise the risk of earth faults and short-circuits. This can be achieved by reinforcing the protection of the wiring either through: a. Single conductor cable – both insulated and sheathed (eg “PV cable”, HO7RNF cables)
