Delta Powers Europe’s Largest Solar Park with 3,500 High-Efficiency Inverters
The 650MW Witznitz Solar Park in Germany, equipped with Delta’s M125HV inverters, generates green energy for 200,000 households annually while reducing carbon emissions by 250,000 tons and supporting regional biodiversity.
Delta has announced it has provided approximately 3,500 Delta M125HV PV inverters to MOVE ON Energy GmbH to power Europe's largest solar power plant, the 650MW Witznitz Solar Park. Located near Leipzig, Germany, this landmark project collectively generates enough green electricity to power 200,000 households annually, translating into a reduction in carbon emissions by over 250,000 tons each year.
“This project marks a significant step forward in our mission to transition from traditional fossil fuels to renewable energy sources. We selected Delta as our inverter supplier for their proven technical expertise and ability to meet the stringent requirements of this large-scale operation,” said Wolfgang Pielmaier, Technical Director and Co-Partner of MOVE ON Energy. “Delta’s inverters provided us with the system certificates necessary for extra-high voltage operations, and their robust performance ensures that we can maximize the efficiency and output of the solar park.”
“The Witznitz Solar Park is a project of superlatives, and we are thrilled to have played a pivotal role in its success. Our team of over R&D engineers worldwide, with more than 25 years of experience in the photovoltaic industry, brought the expertise needed to deliver exceptional performance for this project,” said Andreas Hoischen, Senior Director and Head of Photovoltaic Inverter Solutions at Delta EMEA. “This collaboration with MOVE ON Energy underscores Delta’s commitment to advancing the global energy transition through innovative power electronics.”
Delta’s M125HV inverters, designed to handle the complex demands of high-voltage grid integration, are a critical component of the solar park’s infrastructure. With a peak efficiency of 99.1 percent and features such as intelligent cooling systems and wide MPPT voltage range, these inverters ensure optimal performance even in harsh conditions. The M125HV is designed for 1500V DC and 600V AC systems with one MPP tracker, making it ideally suited for large-scale solar installations like Witznitz. Additionally, these inverters are certified according to VDE-AR-N 4120/4130 standards, crucial for feeding energy directly into the 380 kV grid.
The Witznitz Solar Park is not just impressive in scale but also in its logistical achievements and environmental contributions. The construction involved nearly 30,000 pallets of solar modules, 7,500 module tables spanning 440 kilometers if laid end-to-end, and up to 500 workers at peak times. The energy generated is transmitted through a purpose-built infrastructure that includes 207 transformer stations, ensuring the efficient delivery of power. The park's DC cables alone extend approximately 550 kilometers.
Beyond energy production, the Witznitz Solar Park also emphasizes ecological sustainability. MOVE ON Energy has integrated various biodiversity initiatives, including nesting boxes for birds and bats, rock piles, ponds, and the cultivation of nearly 23 kilometers of field hedges. These measures enhance the local ecosystem, making the solar park not only a source of clean energy but also a contributor to regional biodiversity.
