6 FAQs about [Specifications for laying cables under photovoltaic panels]

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.

What is a photovoltaic cable?

Manufactured in accordance with various British and International Standards, our photovoltaic cables include EN50618 standard, under the harmonised reference H1Z2Z2-K. They are for applications typical of solar farms and rooftop solar installations, providing the interconnection of photovoltaic power generation systems and the solar panel arrays.

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.

What is a solar cable range?

They are for applications typical of solar farms and rooftop solar installations, providing the interconnection of photovoltaic power generation systems and the solar panel arrays. This robust outdoor cable range is designed to withstand severe environmental conditions and degradation from UV light exposure.

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 is a solar power cable?

These cables cover the full range of cable interconnections between the solar panels and the wider components of the photovoltaic system including converter boxes, inverters, transformers, and local grid substations.
