Solar cables for your photovoltaic systems

Complete solutions and project handling for your LAPP PV system

Sustaining tomorrow with solar power.

The future belongs to solar energy. Every year, the sun provides us with around 10,000 times the global energy requirements of mankind. The tremendous potential of the largest energy source cannot be fully exploited, but we can all benefit from it – with photovoltaic systems that make efficient use of the energy. Since the increasing system voltage of modern photovoltaic systems requires equally more powerful cables and components, LAPP has established itself as a leading provider of innovative and high-quality solutions in the field of solar cables and connectors.

On the safe side: norms and standards for the solar industry

Standards provide guidelines for manufacturers, installers and inspectors to ensure that photovoltaic systems provide electricity safely, efficiently and reliably by complying with the quality and safety regulations. Solar solutions from LAPP meet these standards. An overview of the key standards.

VDE (Association for Electrical, Electronic & Information Technologies)

Standards provide guidelines for manufacturers, installers and inspectors to ensure that photovoltaic systems provide electricity safely, efficiently and reliably by complying with the quality and safety regulations. Solar solutions from LAPP meet these standards. An overview of the key standards.

IEC (International Electrotechnical Commission)

This global non-profit committee is active in more than 170 countries and develops international standards for electrical engineering, electronics and related technologies. The IEC standards for solar technology include guidelines for photovoltaic modules, inverters, power measurement, installation, safety and more.

BS (British Standard)

The national standardisation body in Great Britain was the first of its kind in the world. Its standards include guidelines for various aspects of solar technology, which are similar to the IEC standards but can also contain specific requirements for the British market.

The growing system voltage due to increasingly modern PV systems requires equally more powerful cables and components. We at LAPP have been tackling this challenge for many years, and solve the tasks with innovative solutions. To meet the constantly arising challenges caused by system voltage increases, we develop high-quality cables and components with a long service life and extreme robustness as the products are constantly exposed to the wind and weather. Reliable performance requires exceptional weather resistance to heat, wind and frost – and rodent protection is recommended too. At the same time, modern PV systems can supply energy for several decades.

To exploit the full potential of the power supply, the relatively young industry is working on new technologies and applications such as organic photovoltaics (OPV). The photovoltaic industry’s requirements for cabling solutions range from large, robust cables for direct burial in power stations right through to sophisticated connection systems for flexible OPV modules.

All these requirements pose a major challenge – and we are able to offer successful solutions owing to our experience and expertise.

High-quality products and easy assembly are crucial factors when it comes to selection. If one of the cables becomes brittle or malfunctions, it affects all the other cables from the same drum. Since new installations and removals can be very expensive in this case, investing in durable and high-quality material is worthwhile in the long term.

When purchasing a solar connector, please be aware of the following points:

  • Product selection: use the EPIC® SOLAR 4Plus male connector and the EPIC® SOLAR 4Plus female connector made of high-quality, UV-resistant plastic.
  • Crimp connections which have been carried out in a regulation-compliant manner are the best connections between cables and connectors. They reliably transmit solar energy throughout the photovoltaic system’s entire service life – over decades. Our LAPP connector system has a crimp termination for cable cross-sections of up to 10 mm².
  • The TÜV certification and the tests in accordance with the standard DIN EN 62852 (relevant for connectors for DC voltage applications in photovoltaic systems) indicate quality.

We are constantly developing our products and services. Striving for the greatest possible durability, robustness and extreme flexibility is what drives us. Thanks to special sheath materials, LAPP solar cables are not just flame-retardant and halogen-free, they are also resistant to ozone and UV. Our solar cables and solar connectors can also withstand extreme weather conditions such as heat, wind and frost, making them perfect for use in your outdoor systems.
The products in a solar system are exposed to the sun for years. The transmission of energy and the high resistance heat up cables and connectors, while the constant alternation between warm and cold due to the sun’s rays and heating during operation causes cables and connectors to become brittle.

Numerous inspections and performance tests have been carried out with our ÖLFLEX® cables, solar cables, SKINTOP® cable glands and EPIC® SOLAR connectors in close cooperation with customers, the TÜV and the North American UL approval institute. This enables us to guarantee our quality standard. Our products are suitable for use worldwide and, of course, RoHS-compliant.

Can't find the right solar product for your needs? Together, we can develop individual solutions, tailor-made for you. Our experts would be delighted to advise you.

Incidentally: expert knowledge is vital, not only in the selection of the components to be used, but also in the assembly and correct use of the components. We would be happy to support you on site here too.

Everything from a single source. With us as a partner. Our project business team would be pleased to advise you in the planning and implementation of your PV systems.
