GCL Powers Germany's Landmark Agrivoltaic Project with Next-Generation Solar Solutions

On October 15, 2025, Vattenfall officially opened the Tützpatz agrivoltaic power station in Mecklenburg-Vorpommern, Germany. This remarkable facility stands as one of the largest of its kind in Germany, featuring a total installed capacity of 76 megawatts spread across 93 hectares. It consists of 146,000 bifacial high-efficiency solar modules, each with a capacity of 550 watts, produced by GCL System Integration (GCL SI).

GCL, a leading player in the energy sector, provided not only its high-performance solar modules but also tailored solutions essential for agrivoltaic operations. Notably, the project's economic viability was achieved without relying on public subsidies, supported by a 10-year power purchase agreement (PPA) with PASM, a subsidiary of Deutsche Telekom, which will purchase all of the plant's output. This highlights GCL's ability to adapt its technologies effectively across various geographic and regulatory environments.

Innovative Agrivoltaic Solutions

In recent years, GCL has firmly established its position in the agrivoltaic sector. The company has developed specialized solar products that allow customizable light transmittance ranging from 15% to 40%. This feature strikes an ideal balance between efficient solar energy generation and crop cultivation. Their dual-coated glass design and complete aluminum frame successfully passed rigorous tests, demonstrating exceptional durability even in challenging environments, such as those with high humidity or salinity.

The innovative system utilizes 2.8-meter PHC elevated mounting structures along with single-axis trackers, achieving an impressive land-use efficiency that exceeds 80%. These designs allow farmers to access their machines under the panels while ensuring effective light control for crop growth.

Intelligent Agrivoltaic Management

At the forefront of technology, GCL has introduced an intelligent agrivoltaic management platform. This system combines weather data, crop growth sensors, and inverter analytics to optimize panel angles and irrigation schedules using AI algorithms. Remarkably, the 310 MW Zhundong project demonstrated the platform's effectiveness, increasing alfalfa yields by 20% while reducing irrigation needs by 15%. In another project in Anhui, the adjustable mounts also enhanced yields of camellia oilseeds by 30%, concurrently boosting solar efficiency by 8%—offering a true dual harvest of both agricultural products and energy.

Commitment to Sustainability

On August 21, GCL SI made a significant commitment to the Science Based Targets initiative (SBTi), which aligns with their goal of establishing pathways for near-term and net-zero emissions. This promise not only reflects GCL's competitive edge but also its commitment to sustainability and leadership in Environmental, Social, and Governance (ESG) aspects.

GCL's vertically integrated supply chain plays a crucial role in driving down costs, reducing module prices by 8-12% compared to external sources, and further lowering system costs by about 5% through collaborative procurement. The integration of in-house EPC capabilities allows the company to cut project timelines by roughly 20% and reduce overall expenses by about 10%. These benefits have been validated through previous projects in Guangxi, Xinjiang, and Anhui, delivering robust generation performance while contributing to rural development and local economic growth.

Looking Forward

GCL SI is set to deepen its agrivoltaic initiatives in the future. The research into perovskite-silicon tandem modules aims to increase light transmittance, unlocking more synergies between agriculture and energy generation. Concurrently, the company is accelerating the deployment of GW-scale agrivoltaic projects in resource-rich areas of Southwest and Northwest China. By synergizing photovoltaics, agriculture, and carbon traceability into scalable models, GCL SI is dedicated to transforming farmland into efficient ecological power generation sites, significantly contributing to both the energy transition and agricultural modernization.
