Austria's largest solar park is currently under construction in the municipality of Nickelsdorf in Burgenland. With an output of almost 120 MWp, the photovoltaic plant will be able to supply more than 40,000 households in the region with green electricity. For the installation, the Austrian project developer Sonnenbau GmbH relied on the FS UNO single-pile mounting system from the Schletter Group.

"With around 300 sunny days and more than 2,000 hours of sunshine per year, Burgenland is predestined for the generation of solar power," says Fabian Madl, Key Account Manager. "With the Nickelsdorf solar park, the region is further pioneering the expansion of solar energy. At the same time, Austria is entering a new dimension in terms of plant size". On an area of 160 hectares, a total of 220,000 modules will produce electricity for the surrounding residential areas. The first 40 MWp was installed in the spring of 2023. The remaining 80 MWp will follow step by step in the coming months. This means that Austria's largest and highest output solar park will be connected to the grid this year.

The plant, located in the east of Austria close to the Hungarian and Slovakian border, was built using the latest generation of the Schletter FS UNO single-pile system. In addition to its durability, the mounting system's cost-effectiveness was a decisive factor in its selection. "With the FS UNO, a lot of PV power can be installed on fewer supports without structural disadvantages," explains Stefanie Kammerbauer, head of project management. "In addition, it is quick and easy to assemble on site. By optimizing the individual components, the system can be easily adapted to  different terrain profiles and foundations. In Nickelsdorf, conventional pile foundations were used. The advantage: The soil is not sealed and retains its natural functions.

This is not the first project for the Schletter Group in the Alpine Republic. Back in 2020, the company supplied the mounting systems for what was then Austria's largest ground-mounted installation in Schönkirchen. The 15 MWp solar park on a disused landfill site was erected with the FS DUO dual-pile system.
