ÖLFLEX® SOLAR XLWP: Pioneering Permanent Waterproof Solar Cables

LAPP India is a 100% subsidiary of LAPP Germany, a leading supplier of integrated solutions and branded products in the field of cable and connection technology. They are the pioneers in introducing the concept of “Reliably connecting the world” with their unbeatable range of cabling products and solutions. Recently, LAPP launched a new product ÖLFLEX® SOLAR XLWP which is the first permanently waterproof solar cable’ with – Waterproof cable designs, such as the ÖLFLEX® SOLAR XLWP, that are electron-beam crosslinked, ensure that the cable remains fully operational even upon long-term contact with water sources.


In a world where the transition to clean and sustainable energy is not a choice but a business imperative, solar power has emerged as a frontrunner. The journey of solar energy from an experimental technology to a mainstream energy source competing with conventional sources is nothing short of remarkable. Behind the brilliance of solar panels, there are unsung heroes that make it all work – the cables that transmit with minimum losses. Among these, the ÖLFLEX® SOLAR XLWP innovation from LAPP, one of the first permanently waterproof solar cables, is setting the benchmarks for solar energy infrastructure.

As weather conditions get increasingly erratic, working with infrastructure that can withstand the harshest elements becomes a game-changing factor. Waterproof cable designs, such as the ÖLFLEX® SOLAR XLWP, that are electron-beam crosslinked, ensure that the cable remains fully operational even upon long-term contact with water sources, making it the ideal choice for solar installations in regions prone to flooding and excessive moisture. With its enhanced durability, the ÖLFLEX® SOLAR XLWP can withstand mechanical impact, is water resistant, heat resistant, and also UV and ozone resistant. The cable is especially useful in underground applications where cables can be exposed to water, heat, and moisture for a long time.

Safety and sustainability across the solar energy industry are integral features of environmental responsibility. It is important to have cables that adhere to these principles by reducing flame propagation and minimizing the emission of toxic combustion gases in the event of a fire outbreak. Also, industry certifications often include requirements for materials that are halogen-free. It not only contributes to the safety of the installation but also aligns with the industry’s sustainability goals.

The importance of industry certifications cannot be overstated. They are often issued by internationally recognized bodies, such as the International Electrotechnical Commission (IEC) and the European Committee for Electrotechnical Standardization (EN), which provide a vital framework that specifies the quality, safety, and reliability of the components that make up solar power systems. One such certification, (AD8), signifies an advanced level of water tightness, particularly important in the solar energy industry. Cables that meet these standards are designed and manufactured to a high level of quality, ensuring their longevity and efficiency. For instance, solar cables are deemed transversely watertight down to a specific water depth, a critical attribute in the solar energy industry, where water exposure is common.

Certified cables are designed to work seamlessly with other components in a solar energy system. Both compatibility and interoperability are essential for the smooth operation of the system. When all the components meet recognized standards, it reduces the likelihood of technical issues, improves the reliability of the system, and simplifies maintenance and repairs. Solar installations are subject to regulatory requirements across states. Cables that adhere to industry certifications help ensure compliance with these regulations, simplifying the permit and approval processes. It is crucial for the swift and hassle-free deployment of solar projects.

The solar energy industry is not only about harnessing the power of the sun, but it also represents a broader commitment to sustainability, environmental responsibility, and a cleaner future. As the solar energy industry moves forward, innovations, such as the ÖLFLEX® SOLAR XLWP cable become building blocks for larger, more complex systems. They form the backbone of solar farms, rooftop installations, and grid-connected solar power plants. The rise of solar energy is more than a technological shift; it’s a paradigm shift in how we approach energy generation and sustainability.
