Application Advantages of Aluminum Profiles in the Photovoltaic Industry

(1) Balanced Lightweight Property and High Strength

The density of aluminum profiles is approximately 2.7g/cm³, only 1/3 of that of steel. This significantly reduces the overall weight of photovoltaic (PV) systems, lowering transportation costs and simplifying installation. Meanwhile, through alloying and heat treatment processes, the tensile strength of aluminum profiles can reach 200-300MPa, even exceeding that of some low-carbon steels. This enables them to meet the strict structural strength requirements of PV systems, achieving the goal of "lightweight without compromising quality".

(2) Excellent Corrosion Resistance and Long Service Life

PV systems mostly operate in harsh outdoor environments, so the corrosion resistance of materials directly affects the system's service life. Aluminum naturally forms an oxide film in the air, providing basic corrosion protection. After surface treatments such as anodization, electrophoretic coating, and powder coating, the corrosion resistance of aluminum profiles is further enhanced. They can be used for a long time in extreme environments such as coastal areas (high salt spray), deserts (high wind and sand), and high-temperature and high-humidity regions. Their service life can be synchronized with that of PV modules, reaching more than 25 years, which greatly reduces the maintenance costs of the system.

(3) Convenient Processing and Controllable Costs

The extrusion molding process of aluminum profiles is mature. Customized products with different cross-sectional shapes can be manufactured according to the needs of the PV industry, featuring short processing cycles and high precision, which allows quick responses to market changes. Additionally, the recycling rate of aluminum is over 95%, and the energy consumption during the recycling process is only 5% of that for primary aluminum production, which aligns with the green and low-carbon development concept of the PV industry. From a cost perspective, with the optimization of aluminum profile production processes and large-scale application, their costs have gradually decreased. Compared with materials such as stainless steel, aluminum profiles have more cost-effective advantages, making them an important choice for PV enterprises to control costs.

Development Trends of Aluminum Profiles in the Photovoltaic Industry

As the PV industry moves towards high efficiency, large scale, and integration, the application of aluminum profiles in the PV field will also undergo new upgrades. On one hand, to adapt to larger-sized PV modules (such as 182mm and 210mm silicon wafer modules), aluminum profiles will develop towards larger cross-sections and higher precision to improve the load-bearing capacity of brackets and frames. On the other hand, building-integrated photovoltaics (BIPV) has become a new trend. Aluminum profiles will be deeply integrated with building materials to develop integrated products that combine power generation functions with architectural decoration effects, such as PV curtain wall aluminum profiles and PV roof aluminum profiles, further expanding application scenarios.

Furthermore, green and low-carbon development has become an industry consensus. Aluminum profiles for PV applications will pay more attention to the adoption of environmentally friendly production processes, such as using recycled aluminum raw materials and promoting chromium-free passivation technology. These measures will reduce carbon emissions during the production process and help the PV industry achieve the low-carbon development of the entire life cycle. In the future, with continuous technological innovation, aluminum profiles will play a more important role in the PV industry and become a key material driving the development of clean energy.
