Photovoltaic power supply for the bird and weather station on Scharhörn Island
The aim of this project was to commission a reliable power supply for a bird sanctuary station, which would take particular consideration of the requirements in a seabird protection area. The conventional type of power supply with a diesel generator was unsuitable due to problems caused by noise, exhaust and costly maintenance. Wind generators also cause noise and have to be protected from birds in flight, and thus also pose problems. A sea cable for connection to the mains is extremely uneconomical, considering the low power requirements and the large expense necessary for control over high and low tide. The requirements put on the power supply are: (i) no disturbing noise (especially during breeding time); (ii) no exhausts (especially during breeding time); (iii) no moving parts which could be of disturbance to the birds (e.g. wind generator); (iv) unobtrusive presence in the countryside; (v) low maintenance and easy handling; (vi) high availability and reliability, considering the restricted access to the plant resulting from its exposed position. An important task within this project was the development of a special base construction for the solar generator frames, because of the special conditions on Scharhörn. The island is a sand dune in the mud flats, which is washed over by the sea when there are heavy storm floods. In addition, extreme wind speeds are often measured (up to 200 km/h).
