The Lottorf Solar Park is currently the largest ground-mounted photovoltaic system in Germany with a single-axis tracker system. This innovative 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. Delta was chosen as a supplier due to the excellent M88H product performance and efficiency of 98.8 %, but also owing to its excellent partnership and professional competent cooperation from past projects. The 92 Delta M88H_122 inverters installed have a total inverter output of 7360 kW.

After 4 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 megawatts 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.

Andreas Hoischen, Senior Director at Delta explains: "Delta is pleased that our inverters were selected for this special project. 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 utilization of our M88H inverter, which is particularly well suited for such demanding tasks thanks to its robust design."

Active peatland protection through tracking system
Wattmanufactur GmbH & Co. KG has developed an ecological land management concept that is specifically tailored to the site of the former raised bog. The use of rotating modules maximizes the shading possibility of the soil, but at the same time continues to offer a full-surface irrigation possibility. This allows the previously intensively managed peatland soil to recover and return to its most valuable role - CO2 sequestration - in the future.

All effects on soil, flora and fauna are documented and evaluated in a long-term monitoring together with
expert biologists. The area is also farmed ecologically in accordance with the EC Organic Farming Regulation
834/2007 and is certified annually by an independent inspection body. The Lottorf Solar Park thus
demonstrates that renewable energy generation, agricultural use and the creation of a near-natural habitat
can co-exist in harmony.
