Cabling solutions for solar energy
14 October 2009
Interconnection
The energy potential of the sun is almost inexhaustible ... at least 4 billion years, experts estimate. The amount of solar energy arriving on the earth’s surface exceeds by 10 000 to 15 000 times the average daily consumption and this is a major reason why photovoltaic applications have become such an important factor in the area of renewable energy and has influenced a major boom in this business sector.
Through cooperation with users within the renewable energy sector, the Lapp Group has developed a complete product range which has been specifically customised for the photo-voltaic sector. These products are designed to offer complete cabling solutions from the roof to the cellar, for applications where solar cells are connected with each other, or with the terminal box and the inverter.
In developing these solar solutions, Lapp has considered the specific requirements imposed by these applications. In order to transmit electrical currents, theoretically only a copper conductor is required and the insulation and outer sheath merely serve as handling protection. However, particularly in outdoor applications, this protection is exposed to highly demanding weather conditions, UV-rays, ozone and high variation in temperature. The temperature properties of Lapp’s solar cables of, up to +120°C, are able to cope easily with weathering through permanently high temperatures and, as a consequence, they can be installed in hot areas anywhere around the world. This also applies to UV resistance: The reliability of the materials used avoids pre-ageing through becoming brittle and the potential for a breakdown of the cable. Further advantages, such as tinned conductors, cross-linked materials and additional reinforcement, results in better durability and a longer shelf life.
