GCL Contributes Next-Gen Solar Solutions to Germany's Leading Agrivoltaics Initiative

GCL's Innovative Contribution to Agrivoltaics

GCL System Integration, a frontrunner in the sustainable energy sector, has made significant strides in the renewable energy landscape by enhancing Germany's largest agrivoltaics initiative. Officially inaugurated by Swedish energy giant Vattenfall, the Tützpatz photovoltaic plant in Mecklenburg-Vorpommern represents a groundbreaking approach to combining solar energy with agricultural practices. With a total installed capacity of 76 MW spread over 93 hectares, this project utilizes 146,000 bifacial high-performance panels, each rated at 550 watts, supplied by GCL.

As a key technology partner, GCL has not only provided high-efficiency products, but also tailored solutions designed specifically for agrivoltaic applications. The project's economic viability is bolstered by a 10-year Power Purchase Agreement (PPA) with PASM, a subsidiary of Deutsche Telekom, ensuring the full acquisition of the plant's output without reliance on public subsidies. This achievement showcases the adaptability and consistent quality of GCL's solar modules across different geographical and regulatory contexts.

In recent years, GCL has developed a clear trajectory and a robust product portfolio for agricultural photovoltaic solutions. The product line features customizable light transmittance ranging from 15% to 40%, allowing a calculated balance between solar energy generation and crop growth. The bifacial modules are equipped with dual-coated glass and full aluminum frames, having undergone rigorous reliability testing, including 1,000 hours of salt spray exposure and 500 hours of ammonia resistance. This ensures exceptional durability in humid, saline, and livestock-intensive environments.

In combination with PHC mounting structures standing 2.8 meters high and single-axis trackers, the system offers 'machine-accessible, light-controllable' layouts that optimize land use efficiency to over 80%.

In the technological sphere, GCL has devised an intelligent management platform for agrivoltaic systems. By integrating meteorological data, plant growth sensors, and inverter analyses, the system employs AI algorithms to optimize module tilting and irrigation schedules. In the 310 MW Zhundong project, this innovative platform enhanced lucerne yields under the panels by 20% while simultaneously reducing irrigation needs by 15%. Likewise, at the Jinzhai pilot facility in Anhui, motorized adjustable mounts increased camellia seed yields by 30% and enhanced solar efficiency by 8%, enabling a genuine dual harvest of agriculture and energy.

As of August 21, GCL SI has committed to the Science Based Targets Initiative (SBTi), pledging to establish short-term and net-zero emissions reduction pathways in line with SBT methodologies. This milestone underscores the company's commitment to sustainability and establishes it as a leader in Environmental, Social, and Governance (ESG) practices.

Another critical factor is GCL's vertically integrated supply chain, which brings substantial cost advantages. Utilizing its proprietary granular silicon capabilities, the module costs are reduced by 8% to 12% compared to external sourcing. Moreover, through joint procurement with industry partners, overall system costs can be cut by around 5%. With its internal EPC expertise, GCL also shortens project construction times by about 20%, resulting in a total cost reduction of 10%. These strengths have been confirmed through successful initiatives in Guangxi, Xinjiang, and Anhui, which not only deliver robust power generation but also promote rural revitalization and local industrial value creation.

Looking ahead, GCL SI aims to further solidify its leadership in agrivoltaics. Research into perovskite-silicon tandem modules with higher light transmittance is set to unlock even greater synergies between agricultural endeavors and solar power generation. Concurrently, the company is accelerating the rollout of agrivoltaic projects at a gigawatt scale in resource-rich areas of Southwestern and Northwestern China. By integrating photovoltaics, agriculture, and carbon traceability into scalable models, GCL SI is committed to transforming farmland into productive ecological energy sources, contributing to the energy transition and modernizing agriculture.
