What requirements do PV cables have to meet?

Solar cables are part of the Balance of System (BOS) in a PV system and represent only 1-2% of the total installation costs. Nevertheless, they are crucial system components and it is important that they continue to function optimally so that power generation is not disrupted.

 

In July 2014, the first European standard for PV cables was published: Electrical cables for photovoltaic systems. In the Netherlands, NEN-EN 50618 has been in force since 1 January 2015 and according to NEN 1010:2015, the DC cables of a PV installation must be chosen in accordance with NEN-EN 50618.

 

NEN 1010:2015 contains regulations for the application of cable types under certain circumstances. Important environmental factors with regard to the cabling are in particular moisture, temperature and aggressive substances.

Operating temperature

The operating temperature can affect the operation of PV cables and may vary depending on the location.

 

PV cables that are exposed to direct sunlight (UV) can generate more heat by additionally heating up the cable surface. It is therefore important to choose cables with sufficient margin in the operating temperature to avoid any damage caused by extreme cold or heat. Therefore, choose cables with a temperature range of -40 ºC to +120 ºC.

Fire safety

CPR (Construction Products Regulation) is a European regulation that establishes uniform requirements for the essential characteristics and performance of construction products. Cables installed in permanent electrical installations of buildings (e.g., buildings and civil engineering works) fall under the CPR concerning their fire behavior.

NEN 8012 is the standard for fire safety, classifying cables into different (fire) classes. All cable manufacturers must provide a declaration about the fire behavior (CPR classification) of their products and include this classification as part of the CE marking. TECSUN cables are available in the Eca fire class and are self-extinguishing.

EcoCable Label

It is currently difficult for installers and specifiers to determine how sustainable a cable product is. There are no specific, certified eco-labels for the cable industry. This slows down the sustainability and CO2 reduction of electrical installations. To meet the growing demand for proof of environmentally friendly products, parent company Prysmian Group has become the first cable manufacturer to develop its own EcoCable label for cabling.
