Cables and Wires for Photovoltaics

The demand for electricity from renewable energies has been rising significantly for years – photovoltaics plays a central role in this. With the help of the photoelectric effect, sunlight is converted into electrical energy in solar cells. In order to make the energy generated usable, solar cells are connected to modules and integrated into photovoltaic systems.

Photovoltaics is the second largest renewable energy source in Germany – after wind power. In 2025, solar energy covered around 16 percent of the German electricity mix. This has saved more than 60 million tonnes of greenhouse gases. This is impressive proof of how important photovoltaics has become for the energy transition.

The decisive factor for photovoltaic systems is the safe and long-lasting cabling – both of the individual modules with each other and with the inverter. Due to the sometimes extreme weather conditions, the highest demands are placed on the cables. For the cabling of solar modules, HELU offers with the brand SOLARFLEX Thanks to special sheath materials and insulating materials, they are not only flame-retardant and halogen-free, but also resistant to ozone, UV, acids and alkalis, hydrolysis and ammonia. Rodents don't stand a chance either. Our SOLARFLEX cables are also available with rodent protection.
