We are proud to announce the successful completion of our 12,000-ton annual capacity photovoltaic module composite frame project . This isn’t just a production target—it represents a fundamental shift in how the solar industry can think about structural performance, cost efficiency, and environmental responsibility.
The project, developed through rigorous planning and execution, positions our company at the forefront of the composite frame revolution. With this capacity, we are ready to supply the rapidly growing global solar market with high-performance, corrosion-resistant, and lightweight framing solutions .
For decades, aluminum has been the default material for solar module frames. But the industry is waking up to a better alternative. Composite materials—particularly glass fiber-reinforced polymers—offer a suite of advantages that address the critical pain points of modern solar deployment.
1. Superior Strength-to-Weight Ratio
Composite frames deliver axial tensile strength up to five to seven times greater than traditional aluminum alloy, with flexural strength exceeding six times that of conventional materials . This mechanical superiority translates to exceptional wind and snow load resistance, with some designs demonstrating capacity up to 7,000 Pa .
2. Inherent Electrical Insulation
Unlike aluminum, composite frames are naturally non-conductive. This eliminates the need for complex and costly grounding systems, simplifies installation, and significantly reduces the risk of Potential Induced Degradation (PID)—a phenomenon that can permanently reduce module efficiency over time .
3. Unmatched Corrosion Resistance
Aluminum frames can suffer from salt spray corrosion in coastal regions, ammonia exposure in agricultural settings, and chemical degradation in industrial environments. Composite frames are inherently resistant to these challenges, making them ideal for harsh and humid environments .
4. Thermal Stability
The coefficient of linear thermal expansion in composite materials closely matches that of glass, reducing thermo-mechanical stress on the module laminate during temperature cycling . This means fewer micro-cracks and better long-term reliability.
Perhaps the most compelling advantage is environmental. The solar industry exists to reduce carbon emissions—but our manufacturing processes must align with that mission.
Composite frames emit up to 80-85% less carbon during production compared to traditional aluminum frames . When you consider that frames contribute approximately 10% of total module costs and embedded carbon , this reduction is substantial.
Our 12,000-ton capacity enables us to deliver these low-carbon solutions at scale, supporting the industry’s transition to truly sustainable energy systems.
The composite frame market is moving from pilot projects to large-scale deployment. Industry leaders are already building MW-level demonstration projects and securing GW-scale manufacturing capacity .
Frames featuring glass fiber-reinforced polyurethane (GF-PU) technology have earned TÜV certification for fire safety, corrosion resistance, PID mitigation, and mechanical loading performance . Fire resistance ratings have reached the highest Class A and B1 levels for safety .
Beyond performance, composites are becoming increasingly cost-competitive. As aluminum prices fluctuate and supply chains face pressure, composite frames offer a stable, lower-cost alternative that doesn’t compromise quality .
Industry analysis indicates that composite frames can reduce upfront costs by up to 30% compared to conventional aluminum, while delivering superior lifecycle performance . In an era where every fraction of a cent counts, this is a transformative economic advantage.
With the completion of our 12,000-ton project, we are committed to:
Quality and Consistency: Delivering TÜV-certified, reliable products to the global market.
Sustainability: Reducing the carbon footprint of solar manufacturing.
Innovation: Continuously improving material performance and design.
The solar industry is at an inflection point. As global deployment scales toward terawatt levels, the choices we make about materials matter more than ever.
We invite EPCs, developers, module manufacturers, and investors to explore the composite frame difference. Whether you’re building in coastal regions, desert conditions, or simply seeking a more sustainable solution, our 12,000-ton capacity is ready to meet your needs.
