The company exhibited its products at the Intersolar Europe exhibition in Munich

If photovoltaics cables are exposed to damp over a long period of time, this can lead to decreased performance and insulation resistance – the consequence of which may be short circuits, which in turn can lead to failure and damage to the respective equipment. The reason: moisture may infiltrate standard solar cables if they are lying in water for a prolonged period, and can cause failure in the worst-case scenario.

The Stuttgart-based Lapp Group presented the first permanently waterproof solar cable in the form of the ÖLFLEX® SOLAR XLR WP at the Intersolar Europe exhibition in Munich (10th-12th June), at Stand 458 in Hall A2. The cable in question is an electron beam cross-linked solar cable of type PV1-F in accordance with TÜV 2PfG 1169/08.07 for durable, weather-resistant use in photovoltaic systems. Its optimised cable design and the constantly high contact resistance mean that it will still function reliably even after years in the water. The ÖLFLEX® SOLAR XLR WP is a safe alternative – particularly in areas which are prone to flooding, or where cables are installed underground in protective conduits where water, heat and moisture can accumulate.

Lapp also develops and manufactures suitable connection systems which are tailor-made to customer wishes. The most recent example is the revolutionary connection system for organic photovoltaics currently on display in the German Pavilion at the 2015 World’s Fair (Expo) in Milan. Energy-generating solar trees realised using organic photovoltaic (OPV) technology are the focal point of this exhibition. In contrast to conventional solar modules, they consist of flexible, film-integrated OPV modules. The connection technology to produce these came from the Lapp Group.

Lapp has long been making a name for itself as a driving force for innovation in the photovoltaic industry. For over ten years, the company has been successfully developing connection systems for photovoltaic modules and has regularly pushed the market forward with its intelligent innovations, for example the well-known connector system EPIC® Solar and the cable series ÖLFLEX® Solar.
