Vattenfall Inaugurates 76 MW Tützpatz Agrivoltaic Project in Germany with GCL SI Partnership

Swedish energy company Vattenfall has officially inaugurated the Tützpatz agrivoltaic power station in Mecklenburg-Vorpommern, Germany—one of the country’s largest agrivoltaic projects to date. With an installed capacity of 76 megawatts across 93 hectares, the project features 146,000 bifacial 550W high-efficiency solar modules supplied by GCL System Integration (GCL SI).

As a key technology partner, GCL provided both high-performance modules and full-scope delivery capabilities tailored for agrivoltaic applications. The project, completed without public subsidies, is supported by a 10-year power purchase agreement with PASM, a subsidiary of Deutsche Telekom, which will purchase all the electricity generated. This milestone demonstrates the economic viability and adaptability of GCL’s solar technology across varied regulatory and environmental contexts.

GCL has developed a specialized portfolio for agrivoltaic systems, featuring modules with customizable light transmittance (15–40 percent) to balance solar output and crop growth. The modules’ dual-glass design and aluminum frames have undergone extensive durability testing, including 1,000 hours of salt mist and 500 hours of ammonia exposure, ensuring longevity in humid and agricultural environments. Combined with 2.8-meter elevated mounting structures and single-axis trackers, the system allows for high land-use efficiency—exceeding 80 percent—while supporting mechanized farming operations.

GCL has also developed an AI-driven agrivoltaic management platform that integrates meteorological data, crop sensors, and inverter analytics to optimize panel angles and irrigation schedules. The platform has already demonstrated success in improving crop yields and resource efficiency at multiple large-scale sites, including the 310 MW Zhundong and Jinzhai pilot projects in China.

In August 2025, GCL SI formally joined the Science Based Targets initiative, committing to near-term and net-zero emission reduction targets. The company’s vertically integrated supply chain provides significant cost advantages, reducing module costs by up to 12 percent and project timelines by about 20 percent.

Looking ahead, GCL SI plans to advance research into perovskite-silicon tandem modules and expand gigawatt-scale agrivoltaic developments across Southwest and Northwest China. By combining solar generation, agriculture, and carbon traceability, GCL SI aims to transform farmland into productive, sustainable energy ecosystems, driving progress in both the energy transition and agricultural modernization.
