Contributing to a New Benchmark in Rooftop Photovoltaics at Shenzhen Convention & Exhibition Center

Release time: 2025-12-19 10:06:40

Creating an International Green Benchmark in the Greater Bay Area with Technology and Scale
The rooftop photovoltaic-storage-charging integrated project at the Shenzhen Convention & Exhibition Center, undertaken and completed by Boyang Energy, has been successfully grid-connected and serves as the energy demonstration venue for the 2025 International Digital Energy Exhibition. With an installed capacity of approximately 20 MWp, this project has set a new regional record for “single-rooftop distributed photovoltaics” and achieved multiple technological breakthroughs in design, construction, system integration, and landscape compatibility.

Why This Is an “Exceptional” Project

• Massive Single Rooftop with Complex Structure: The Convention & Exhibition Center’s roof is vast and structurally diverse, combining large-span structures with curved surfaces. The installation of PV supports across 30-meter and 60-meter spans without floor layers posed extremely high requirements for support design, load/waterproofing treatment, electrical foundations, installation, and safety. The building itself is widely recognized in international architectural awards and among large convention centers, and the complexity of its rooftop has attracted extensive industry attention.

• Record-Setting Installed Capacity: With a scale approaching 20 MWp, the project has been reported as “one of the largest distributed single installations in the Greater Bay Area,” offering significant demonstration value.

• Dual Role in Exhibition and Urban Image: The project provides green energy support for major events such as the Digital Energy/International Energy Exhibition held at the center in 2025, while also serving as a “l(fā)ow-carbon landmark” for the city, achieving harmony between energy and aesthetics.

Boyang Energy’s Technological and Delivery Highlights (Quantifiable/Replicable)

1. Customized Structure and Support System Design
   To address the complex rooftop with large spans, curved surfaces, and integrated equipment, Boyang Energy adopted zoned modular layouts, customized lightweight supports, and incorporated roof drainage/waterproofing into the PV support design during the early planning phase. This approach reduced risks associated with secondary modifications, simplified acceptance processes, and ensured safety and aesthetic integration with the building through elevation verification, span-by-span measurements, and single-line control.

2. High-Reliability Components and Typhoon/Weather Resistance Strategy
   In the supply chain, Boyang Energy prioritized high-power-density modules and reinforced connectors through comparative selection, ensuring all products passed anti-PID testing and typhoon certification. Installation involved upgrading traditional techniques and incorporating adhesive fastening technology to guarantee module stability and resistance to typhoons up to Category 12. Wind simulation and load joint verification further ensured long-term power generation safety and stability—a strategy critical for managing levelized cost of electricity and operational risks in large public building PV projects.

3. Digital Grid Connection and Energy Management
   The project integrates PV power generation, energy storage, and fast-charging subsystems (solar-storage-charging), combined with sensors and a digital operation platform. This enables real-time power optimization, surplus electricity feed-in regulation, and energy supply保障 during exhibition peak periods. Such “solar-storage-charging integration” represents a key trend in current digital energy scenarios and has been prominently featured in multiple international and domestic exhibition projects.

4. Engineering Execution and Timeline Management
   While ensuring safety and quality, Boyang Energy implemented parallel construction in zones and pre-assembly strategies to handle the unprecedented scale and weight of sunshade panels. This significantly shortened the construction timeline, reduced on-site高空作業(yè) complexity, and enhanced safety. The project strictly adhered to national and international standards, ensuring smooth progress in final acceptance and grid connection. Notably, foundations for equipment such as箱變 and prefabricated cabins were installed at heights of 30 meters, with the equipment itself assembled using split吊裝 and拼裝 methods.

5. Landscape Integration Design
   Specialized designs were applied to module color selection, layout density, and配合 of nighttime lighting, achieving dual value as “power generation by day,景觀 by night.” This makes the PV array an integral part of the Convention & Exhibition Center’s urban image—aligning with the傳播 logic of modern BIPV and city-level demonstration projects.

This project has not only withstood the strongest typhoon in a decade unscathed,實戰(zhàn)驗證了 Boyang Energy’s design strength and operational resilience, but has also added luster to Shenzhen’s urban image. Its successful grid connection and demonstration further highlight Boyang’s technological and delivery capabilities in large, complex public building photovoltaics, providing a replicable engineering model for “integration of energy and exhibitions” and “fusion of solar, storage, and charging” in the Greater Bay Area and nationwide. Moving forward, Boyang Energy will build on this achievement, consistently bringing technological innovation, cost control, and full-lifecycle service capabilities to more urban landmarks, seamlessly integrating energy with urban aesthetics.
