The Hallig is only inhabited by a bird warden every six months and, due to its location in protection zone 1 of the Wadden Sea National Park, is not normally accessible to other people. In order to supply the island with electrical energy, a small team from AEROCOMPACT was able to accompany the installation of the 3.56 kWp PV system. Together with SPR Energie, all the material was transported to the island on a small cutter, with particular caution required due to high and low tides and the need for rapid installation.
SALT AIR AND WIND AS CONSTANT COMPANIONS
The extreme conditions on the Hallig are reflected in the salt content of the air. At high tide, the base structure is flooded and reaches the foundation walls, which lie at 1m above sea level. The components of the AEROCOMPACT substructures are designed for salty air and can therefore optimally withstand natural corrosion. The wind load is a further challenge for installation on the unprotected, 6-hectare island. “AEROCOMPACT supported us with this project and used its AEROTOOL program to calculate exactly how we can and may erect the module,” says Dirk Bruhn, Project Manager at SPR Energie.
QUICK ASSEMBLY AND DISMANTLING WITH COMPACTGROUND G
During the cold months, the Hallig is uninhabited and must be made winter-proof. The system is therefore also dismantled and stowed away in the fall. As one of the fastest open-air systems in the industry to set up, our COMPACTGROUND G offers the best assembly times and transportation cost efficiency. “This is also a criterion that was important to us,” adds Bruhn. The system is therefore also ideally suited for temporary project installations.
