This type of vertical wind power plant is especially suited for locations where conventional plants based on horizontal wind turbine design can or may not be installed. Thanks to highly transparent Makrolon® solid sheets from Bayer MaterialScience, the innovative EURO SuperSilent wind power plant does not cast any hard shadow, which in plants with horizontal wind propellers is often perceived as disturbing.

Darmstadt, Germany, September 3, 2014 – At first sight the wind power plant looks like a wind sculpture, and it fits into its surroundings in an equally unobtrusive manner. The Makrolon® UV clear solid sheets from Bayer MaterialScience do not only make the EURO SuperSilent wind power plant a structure that is barely noticeable, they also turn the plant into an efficient and sturdy lightweight installation with an impeccable ecological balance sheet, from production to disposal.

This type of vertical wind power plant is especially suited for locations where conventional plants based on horizontal wind turbine design can or may not be installed because they are either too large, too costly, or raise ecological concerns, such as in areas with mixed residential and commercial zoning, or in exclusively residential areas. Thanks to the highly transparent Makrolon® solid sheets, the EURO SuperSilent wind power plant does not cast any hard shadow, which in plants with horizontal wind propellers is often perceived as disturbing. Because the polycarbonate sheets from Bayer MaterialScience have a low weight per unit area, the plant is particularly lightweight yet highly robust. The combination of Makrolon® UV clear solid sheets with saltwater-resistant wood composite make the modular installation a lightweight installation that is suitable for wind speeds from 4 to 12 Beaufort. Maritime guy-ropes provide additional storm protection.

The plant does not require energy-consuming start-up that is common in most conventional wind power plants with propeller design. The plant features an optimized start-up, which is mainly made possible by the sophisticated design of the specially shaped wind turbines of Makrolon®. Because the material is easy to process and can be flexibly shaped, it was possible to tailor the wind turbines precisely to take up maximum wind power in any wind speed. In the presence of suitable wind, the currently largest plant with 12 wind modules reaches a peak of 4.8 kW.

It is not only the moderate price compared to high-end photovoltaic installations and the short amortization period of three to four years that make this wind power plant a low-cost solution, both for insular grids and for feeding into a large grid. The plant can also be added on to existing photovoltaic plants, possibly without any extra site preparation. During its lifespan of about ten years, the plant is maintenance-free.

The ecological balance sheet for the Makrolon® sheets used in the wind turbines is exemplary from beginning to end. The polycarbonate sheets are free of halogens and heavy metals and contain only ecologically harmless components. The only waste that is generated during the installation and processing of the sheets can be recycled in the processing circuit. Even at the end of its life span, the wind power plant is ecologically harmless. Polycarbonate consists mainly of carbon, hydrogen and oxygen, so when Makrolon® polycarbonate sheets are incinerated for disposal, there is no relevant toxicity risk.

With an installation time of one day at the most, the wind power plant can be installed quickly and on short notice. And with its height of 10 meters maximum, and its robust, transparent wind turbines the plant is also a perfect solution for developing and emerging countries. For example, the plant can provide the energy to pump water from a well up to 100 meters deep, and simultaneously deliver electricity or lighting in healthcare stations or schools, or for publicly shared stovetops.
