Powered by CENTER INT & LONGi | China's Largest! PV Project at Xiamen Xiang'an International Airport Successfully Grid-connected

Amidst the blue sky and sea on the western side of the Taiwan Straits, a highly anticipated aviation hub is rapidly taking shape. As the largest new airport constructed during China's "14th Five-Year Plan" period and the core carrier of the Maritime Silk Road gateway hub, the construction progress of Xiamen Xiang'an International Airport has always been a focus of attention. Within this mega-project, with a total investment exceeding RMB 55.5 billion, the finger pier and cargo area photovoltaic project, jointly developed by CENTER INT and LONGi, with a total installed capacity of 22.8MW and area of 170,000 square meters, has become the largest airport photovoltaic project in China's terminal finger pier area to date.

It not only provides critical support for the airport's green energy system but also solves key safety challenges of photovoltaic applications in airport scenarios through core technological breakthroughs, offering a robust system solution for the green transformation of large hub airports.

As a Class 4F international hub airport in the Western Taiwan Straits region, Xiamen Xiang'an International Airport is tasked with the vital functions of connecting the region and linking to the globe.

At the policy level, it aligns closely with regional development plans and features a systematic design capable of radiating and driving growth in surrounding areas. Operationally, upon completion, the airport will fundamentally resolve the long-standing capacity constraints of Xiamen Gaoqi Airport. The first phase is designed for an annual passenger throughput of 45 million and cargo throughput of 750,000 tons, significantly strengthening the radiation capacity of the Western Taiwan Straits aviation hub and helping the southwestern Fujian region integrate more deeply into the global industrial chain.

Crucially, this island-type airport, built on reclaimed land, has overcome a series of engineering challenges such as soft soil foundation settlement and strong typhoon defense. It has also made "green and low-carbon" a core construction principle, vigorously promoting the application of renewable energy. The implementation of the photovoltaic project is a vital manifestation of this philosophy.

The core challenge for airport PV applications lies in the potential interference of glare from PV module surfaces on flight safety, a difficulty that has hindered or forced adjustments to PV project plans at numerous airports worldwide. The reason the Xiamen Xiang'an Airport PV project has become an industry benchmark lies in the full-chain technological and engineering breakthroughs brought about by the collaboration between CENTER INT and LONGi.

As leaders in the building metal envelope and photovoltaic industries respectively, CENTER INT's profound building system expertise and LONGi's leading high-efficiency PV technology have been precisely integrated. This has created dual advantages in "technology R&D + engineering implementation," enabling the integration of full-chain capabilities from product innovation and customized design to high-standard delivery, going far beyond simple product supply.

The project's key technological support stems from LONGi's anti-glare high-efficiency PV modules, which fundamentally eliminate any potential interference with pilots' vision and tower command systems, thus clearing the "last mile" for large-scale PV application in core airport areas.

Technological leadership must be rooted in a profound understanding of special airport application scenarios. The CENTER INT & LONGi project team innovatively implemented the "safety adaptation" concept throughout the entire project process, ensuring deep alignment between the technical solution and airport operational scenarios:

Dual Evolution in Optics and Structure: While achieving high conversion efficiency, the mechanical structure of the modules was specifically optimized for coastal strong typhoon and high salt-spray environments, strictly matching the terminal roof's load specifications and wind uplift resistance requirements.

Digital Twin Enables Precision Construction: The project fully implemented the "no model, no construction" BIM (Building Information Modeling) concept and introduced 3D laser scanning technology for millimeter-level verification of the building. This ensured that thousands of modules were precisely installed on the complex curved roof with zero error, achieving "excellence in one go."

Scenario-Based Safety Zoning Design: For areas with different safety levels, such as finger piers (close to aircraft activity areas) and cargo areas, the team finely adjusted the PV installation tilt angles and array layout plans. This achieved an optimal balance between ensuring safety and maximizing power generation benefits.

The significance of the Xiamen Xiang'an International Airport PV project extends beyond a single energy supply function, reflecting the multiple values of modern engineering construction.

Safeguarding the Green Operation of Major Infrastructure. It demonstrates the feasibility of achieving large-scale local consumption of clean energy within infrastructure characterized by high safety requirements and complex operating environments. Over 25 years, the project is expected to generate approximately 610 million kWh of electricity and reduce CO2 emissions by nearly 600,000 tons, injecting strong green energy momentum into this super transportation hub. Defining a New Standard for Green Airport Construction. The project has achieved substantial breakthroughs in the safety of PV applications within core airport areas, providing a reference technical path and practical example for low-carbon development in the airport sector. It showcases the harmonious integration of "safe operation" and "green low-carbon" through technological innovation. Demonstrating Corporate Capability in Serving Major Projects. The "scenario + technology" dual-brand model of CENTER INT and LONGi can efficiently respond to the ultra-high requirements of complex projects like hub airports and large transportation facilities, transforming technological advantages into high-quality engineering practice.

Beneath the blue sky and beside the blue sea, the silver wing roof of Xiamen Xiang'an International Airport is quietly transforming into a vast, "non-glare" energy fertile ground. Every kilowatt-hour generated here embodies the utmost respect for flight safety and demonstrates the practical spirit of promoting clean energy applications. It is more than just an energy project; it is a systemic innovation, offering valuable insights for the sustainable development of the aviation industry and related fields with high safety requirements.
