Worldlight New Materials' 21st CSPV Major Release: Composite Material Frame Solution More Suitable for Offshore Power Plants

Riding the wave of the era when photovoltaics and marine energy are converging, the 21st China Solar-grade Silicon and Photovoltaic Power Generation Symposium (CSPV) was grandly held in Huainan. As a pioneer in the field of photovoltaic material innovation, Worldlight New Materials Co., Ltd. was invited to attend this prestigious event and delivered a special technical report titled “Reliable Protection in Extreme Environments—Composite Material Frames Better Suited for Offshore Solar Power Plants,” providing a crucial material solution for the large-scale development of offshore photovoltaics.

As of the first half of 2025, the global installed capacity of offshore photovoltaic power generation is approximately 2 GW, with China accounting for about 1.6 GW of that total. It is projected that by 2030, the globally新增 installed capacity of offshore photovoltaic power will reach 45–50 GW, with an average annual growth rate expected to exceed 50%. Of this, China is likely to contribute more than 70% of the新增 installed capacity.

Offshore photovoltaic power plants are emerging as a new blue ocean in the global energy transition. However, the harsh marine environment—characterized by high salinity, high humidity, intense ultraviolet radiation, wind and wave loads, and even biofouling—poses an enormous challenge to every single detail of photovoltaic components. The corrosion risk associated with traditional metal frames has become one of the key bottlenecks limiting the lifespan and safety of offshore PV systems.

Building on its years of deep expertise in the field of composite materials, Worldlight New Materials has precisely targeted this challenge and successfully developed a new-generation high-performance composite material frame designed to fundamentally address the corrosion issues posed by marine environments and ensure the reliability of power plants throughout their entire lifecycle.

In this CSPV report, Zhan Bin, Marketing Director of Worldlight New Materials, elaborated in detail on how its composite material frames have undergone systematic innovation specifically tailored for offshore environments:

1. Ultimate corrosion resistance, innate immunity

By employing a specialized composite material system, we fundamentally eliminate electrochemical corrosion and salt-spray erosion. In long-term salt-spray testing, this material performs far superior to metal frames, truly enabling coexistence and mutual prosperity with the marine environment.

2. Lightweight and high-strength, with wind- and earthquake-resistant properties.

The material’s density is significantly lower than that of aluminum, markedly reducing the weight and load of the component. Meanwhile, thanks to its unique structural design and advanced reinforcement techniques, its mechanical strength as well as its resistance to wind pressure and vibration performance meet or even exceed the most stringent design requirements for coastal and offshore power plants.

3. Long-lasting weather resistance, consistently stable.

A specialized formulation ensures that the material maintains excellent mechanical performance and dimensional stability over the long term under intense ultraviolet radiation and humid-thermal cycling, preventing aging and embrittlement and guaranteeing a service life of more than 25 years for power plants.

4. Insulated lightning protection, enhancing safety and efficiency

Composite materials themselves possess excellent insulating properties, which can reduce the risk of hidden cracks in components, simplify lightning protection design for the system, and enhance the overall system safety.

More than just materials—this is a systematic enhancement of value!

The report further points out that Worldlight New Materials' contribution goes beyond simply providing a corrosion-resistant material—it delivers systemic value enhancement to offshore photovoltaics through comprehensive optimization across the entire chain, including frame structure design, connection solutions, and installation processes:

· Reduced operational and maintenance costs: No need for corrosion prevention maintenance, significantly reducing the frequency of high-risk offshore operations.
· Enhance power generation revenue: Insulation properties reduce the risk of PID degradation, ensuring more stable long-term power generation performance.
· Accelerated installation and deployment: Designed for easy offshore transportation and installation, reducing construction complexity and costs.
· Green and sustainable: The production process consumes less energy, and the carbon footprint over the entire lifecycle is significantly advantageous.

At the CSPV presentation venue, Worldlight New Materials' forward-looking research sparked keen interest and lively discussions among industry experts, power plant investors, and design firms. Everyone unanimously agreed that, in facing extreme environments such as marine settings, technological innovations represented by composite material frames are an inevitable choice for photovoltaics to move toward the "deep blue."
