Germany"s largest solar park relies on Delta inverters for single-axis tracking
Wattmanufactur, a long-standing partner of Delta Electronics, recently opened the Lottorf Solar Park with the Germany federal party chairman Dr Robert Habeck in attendance. The 10 MWp solar park in the district of Schleswig-Flensburg/Schleswig-Holstein is currently the largest ground-mounted photovoltaic system in Germany with a single-axis tracker system that follows the sun from east to west.
Compared to conventional static installations, this solar park generates significantly more energy in the morning and evening hours with the help of 23,184 bifacial solar modules, thus exhibiting more consistent power production throughout the day. The Lottorf Solar Park also complies with the latest grid connection guidelines and can make an important contribution to grid stability by providing reactive power during the day and at night.
After four months of construction, the EEG (Renewable Energy Sources Act)-eligible photovoltaic open space was connected to the grid of Schleswig-Holstein Netz AG. In the coming year, the total output of the ecologically designed solar park will be expanded by another 7 MW of rated output, bringing the total to 17 MWp. The Lottorf Solar Park will then generate around 20 million kilowatt hours annually and supply around 5,700 households with renewable energy.
A key element in this ground-mounted photovoltaic system is the M88H inverter from Delta Electronics, chosen due to its performance and efficiency of 98.8 %, but also owing to the partnership between the companies in past projects. The 92 Delta M88H_122 inverters installed have a total inverter output of 7360 kW.
Andreas Hoischen, senior director at Delta Electronics, explains: “The single-axis tracker system makes it possible to feed in significantly more solar power in the morning and evening compared to fixed setups. This means a much higher utilisation of our M88H inverter, which is particularly well suited for such demanding tasks thanks to its robust design.”
