Photovoltaics – Energy of The Future
1. A glance at the solar power
1.1 The demand for renewable energy
The demand for electricity from renewable energy sources has been increasing significantly for years - in order to meet this demand, the generation of electricity through Photovoltaics is essential. In this process, energy from the sun's rays is converted into electrical energy in solar cells using the photoelectric effect. To make access the converted energy, solar cells are connected to modules and integrated into photovoltaic systems.
Photovoltaics now represent the second-largest share of renewable energy generation in Germany, directly behind wind power. In 2019, almost 30 million tons of carbon dioxide were saved. This makes photovoltaics a sustainable and environmentally friendly form of energy.
1.2 Requirements for cables used in photovoltaic systems
Important to photovoltaic systems is the safe and long-lasting cabling of the individual modules among each other as well as also the cabling of the elements with the inverter. Due to the occasional extreme weather conditions outdoors, strict requirements are placed on the cables.
Reliable and durable cabling of the individual solar modules with each other and the cabling to the inverters and storage systems is crucial for efficient operation of the systems. This is where cables are needed that reliably withstand all external influences - this is the only way to get the energy generated to where it is needed. As a leading manufacturer and supplier of electrical connection technology, HELUKABEL has decades of experience in the photovoltaic industry - and supplies the ideal cables and wires as well as the right accessories for every application.
2. HELUKABEL's product portfolio for photovoltaic systems
We offer a broad range of products, from DC string cables for connecting solar panels, to earth and medium-voltage cables for connection and grid feed-in, to fibre optic and data cables for networks and communication.
For the cabling of solar modules, we offer the SOLARFLEX® brand of high-quality cables certified by TÜV. Thanks to special sheathing 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. Even rodents don't stand a chance against this cable, because our SOLARFLEX® cables are also available with rodent protection.
In addition, we offer integrated cable management systems including connectors, plugs, hoses, glands, housings and tools, as well as pre-assembled cables. Our experts are particularly competent in developing customised solutions for special applications - and thanks to our global presence, all local and regional requirements such as environmental conditions and design standards can be met. HELUKABEL thus supports manufacturers, installers and operators of photovoltaic systems worldwide in generating clean, sustainable and renewable energy.
