On December 2, 2025, the Standardization Administration of the People's Republic of China (SAC) officially issued the 11th batch of recommended national standard plans for 2025. The national standard "Fiber-Reinforced Composite Profiles for Photovoltaic Modules" (Plan No.: 20256504-T-609), led by Zhejiang Deyilong Technology Co., Ltd. and jointly drafted with China Fiber Composite Renewable Resources Consulting & Service (Beijing) Co., Ltd., has been successfully approved! The simultaneous launch of the foreign language version development marks that China's photovoltaic composite material technical standards are about to step onto the global stage.
Currently, 90% of the world's photovoltaic (PV) modules are produced in China, and the core R&D and production capabilities of fiber-reinforced composite frame profiles are concentrated domestically, making Chinese technology a global industry benchmark. However, with the rapid industrial expansion, the industry faces key bottlenecks:
- Coexistence of multiple standards and inconsistent technical requirements, leading to a lack of unified basis for enterprise production and confusion for users in product selection;
- In the trend of new composite material frames replacing traditional aluminum alloy frames, there is a lack of recognized performance evaluation systems;
- Surging export demand, with insufficient connection between domestic standards and international certifications (such as TUV, VDE).
The introduction of this national standard will fundamentally solve the above problems by unifying product classification, clarifying core indicators, and standardizing testing methods. It will establish a reliable technical benchmark for the entire industrial chain, guide the industry to shift from "scale competition" to "performance and reliability competition," and lay a solid foundation for the coordinated development of upstream and downstream sectors.
Deyilong's qualification as the leading unit for this key national standard stems from its profound accumulation and industry responsibility in the composite material field:
- Boasting over 30 years of experience in pultrusion production of composite profiles and 10 years of specialized R&D history in PV frames, Deyilong's independently developed GRPU glass fiber-reinforced polyurethane composite frames have been widely applied in large-scale ground-mounted power stations, offshore PV projects, western large-scale bases, BIPV (Building-Integrated Photovoltaics) and other scenarios in China, Europe, the United States, Brazil and other emerging markets, thanks to core advantages such as high strength, low expansion, high corrosion resistance, strong insulation, and low carbon emissions.
Leveraging China's global discourse power in the PV industry, this standard specifically promotes the simultaneous development of a foreign language version. Behind this decision is Deyilong's accurate judgment of industry trends:
- Major domestic module manufacturers are actively expanding overseas markets through international authoritative certifications such as TUV and VDE, and the foreign language version of the standard will realize seamless connection between domestic technical specifications and international certification systems;
- As an environmentally friendly alternative under the "dual carbon" strategy, the internationalization of China's standards for fiber-reinforced composite frames will help Chinese PV products establish greater discourse power in the global market;
- A unified international standard will reduce certification costs for export enterprises and accelerate the global output of China's composite material technology.
The formulation of this national standard is not only a milestone in industry standardization but also a signal for fiber-reinforced composite frames to accelerate the replacement of traditional aluminum alloy frames. With the implementation of the standard, it will further activate the tens-of-billions-yuan emerging market and promote the PV industry to take a key step forward in cost reduction, efficiency improvement, and environmental upgrading.
As the leading unit, Deyilong will unite high-quality industry resources, uphold the mission of "Driving Material Innovation, Creating a Better Life," and complete the standard compilation with high standards, enabling mutual empowerment between technological innovation and industry norms. In the future, Deyilong will continue to take innovation as the core and standards as the guide, providing Chinese solutions and contributing Deyilong's strength to the high-quality development of the global PV industry!
