GCL Supports Innovative Agrivoltaic Project in Germany

GCL System Integration has become a cornerstone in the establishment of Germany's largest agrivoltaic initiative. This remarkable project, inaugurated by the Swedish energy leader Vattenfall, is located in Tützpatz, Mecklenburg-Vorpommern, and represents a significant step forward in sustainable energy and agricultural synergy.

The photovoltaic facility boasts a total installed capacity of 76 MW, spread across 93 hectares, utilizing 146,000 high-efficiency bifacial solar modules rated at 550 watts, all manufactured by GCL. As a key technology partner, GCL not only provided superior products but also tailored delivery capabilities for photovoltaic applications.

The project's financial feasibility is impressive, as it was executed without public subsidies. It is supported by a ten-year Power Purchase Agreement (PPA) with PASM, a subsidiary of Deutsche Telekom, ensuring the entire energy output will be absorbed by them. This achievement highlights the adaptability and resilience of GCL’s modules in diverse geographical and regulatory settings.

In recent years, GCL has established a robust portfolio of photovoltaic solutions, including a specially designed product that offers customizable light transmission between 15% and 40%. This feature ensures a perfect balance between solar energy generation and crop growth. The double-coated glass and fully aluminum frame of the modules have undergone rigorous reliability testing, including 1,000 hours of salt mist exposure and 500 hours of ammonia exposure, confirming outstanding durability in humid, saline environments and high-density livestock areas.

To maximize efficiency, the installation incorporates 2.8-meter high PHC mounting structures combined with single-axis trackers. This configuration allows for “machine-accessible and light-controllable” layouts, enhancing land utilization efficiency by over 80%.

At the forefront of technology, GCL has developed an intelligent photovoltaic energy management platform. This platform integrates weather data, crop growth sensors, and inverter analysis, employing artificial intelligence algorithms to optimize module tilt angles and irrigation scheduling. During the Zhundong project, a 310 MW initiative, the platform resulted in a 20% increase in alfalfa yields under the panels while reducing irrigation needs by 15%. Additionally, in the pilot modernization project in Jinzhai, Anhui, automated adjustable supports led to a 30% rise in camellia seed oil crop yields and an 8% boost in solar energy efficiency, achieving genuine “dual harvests” in both agriculture and energy sectors.

Furthermore, GCL SI has publicly committed to the Science Based Targets initiative (SBTi) as of August 21, pledging to establish short-term emissions reduction trajectories and attain net-zero emissions following the SBT methodologies. This commitment emphasizes the company's responsibility and competitiveness in sustainable development and ESG leadership.

GCL's vertically integrated supply chain plays a crucial role in delivering substantial cost benefits. By leveraging the group's proprietary granular silicon capabilities, module costs are reduced by 8 to 12% compared to external sourcing. Joint sourcing with industrial partners further cuts system-wide costs by approximately 5%. GCL’s EPC expertise allows for a 20% reduction in project construction timelines and a 10% decrease in overall costs. These advantages have been consistently validated in projects across Guangxi, Xinjiang, and Anhui, which not only deliver strong production performance but also contribute to rural revitalization and local industrial value creation.

Looking ahead, GCL SI aims to solidify its leadership position in photovoltaic energy. Research on higher light transmission perovskite-silicon tandem modules is underway, targeting even greater synergies between agriculture and solar energy production. The company is also advancing the deployment of GW-scale photovoltaic projects in resource-rich regions such as Southwestern and Northwestern China. By intertwining solar energy, agriculture, and carbon traceability into scalable models, GCL SI is committed to transforming agricultural lands into productive, eco-friendly energy bases that support both energy transition efforts and agricultural modernization.
