Recently, the 3.4 MW distributed photovoltaic project at a wastewater treatment plant in Suqian City was successfully connected to the grid. This power station adopts Worldlight New Materials' innovative composite frame solution and achieved a peak daily generation capacity of 18,000 kilowatt-hours, successfully establishing a benchmark project in the industry that synergistically integrates "wastewater treatment with clean energy." The project not only breaks through the conventional limitations of photovoltaic application scenarios but also overcomes technical challenges in complex industrial environments through material innovation.
In terms of adaptability to harsh operating conditions, the composite frame from Worldlight New Materials demonstrates outstanding performance advantages. Wastewater treatment plants are long-term exposed to severe environments characterized by high humidity, abundant acidic and alkaline substances, and salt spray erosion—conditions that pose a significant challenge to the durability and stability of power plant equipment materials. In such environments, conventional frame materials are prone to corrosion and rusting, which can adversely affect the normal operation and service life of power plants. Thanks to its exceptional resistance to corrosion, acid and alkali, and salt spray, the composite frame from Worldlight New Materials has successfully overcome these challenges, providing a solid guarantee for the stable operation of power plants.
It’s worth noting that the composite frame used by Worldlight New Materials is an insulating material and does not conduct electricity. This feature offers a dual advantage: On the one hand, power plant operators no longer need to implement protective grounding, greatly simplifying the installation process and reducing installation costs. On the other hand, it effectively mitigates the risk of PID (Potential Induced Degradation). In conventional photovoltaic systems, since component frames are grounded, under humid conditions and high-voltage environments, PID is prone to occur, significantly reducing the power generation efficiency of photovoltaic modules. However, the composite frame used by Worldlight New Materials fundamentally avoids this issue, ensuring stable power generation efficiency of photovoltaic modules, extending their service life, and laying a solid foundation for the long-term, efficient operation of power plants.
In terms of industrial aesthetic and eco-friendly design, Worldlight’s composite frame comes in black, offering unique advantages over the commonly used aluminum-colored metal frames. The black frame harmonizes more seamlessly with the overall design of power station equipment, adding a simple yet sophisticated industrial aesthetic to the power station and transforming its appearance from the somewhat monotonous look of traditional power stations. In terms of controlling light pollution, the black frame effectively reduces light reflection and minimizes light pollution. This not only aligns with the concept of green and environmentally friendly development but also creates a more comfortable visual environment for the surrounding area and personnel, reducing the stimulation and interference caused by intense light to human eyes.
According to the project’s technical director, this solution significantly reduces costs compared to traditional approaches, with particularly notable reductions in operation and maintenance costs. Worldlight New Materials has established a comprehensive technology system covering material R&D, structural design, and process optimization. Its composite-frame products have obtained TÜV international certification and boast significant competitive advantages in specialized scenarios such as chemical industrial parks and coastal photovoltaic installations. The successful implementation of this Suqian project marks an important breakthrough for China in the field of new photovoltaic system solutions, providing a replicable Chinese approach for photovoltaic applications in industrial settings worldwide.
