Traditional aluminum alloy frames are prone to oxidation and corrosion in harsh environments such as coastal salt spray, desert wind and sand, and chemical parks, which leads to sealant damage, glass cracking and reduced power generation efficiency. Composite PV frames have excellent resistance to salt spray, ammonia, ultraviolet rays and aging, and can operate stably in the range of pH 2-12. After 1000 hours of neutral salt spray test in accordance with IEC 61701 standard, there is no corrosion trace on the surface; even after 3000 hours of severe salt spray test, the glossiness can still be maintained above 95%. This advantage makes it widely used in coastal, desert,滩涂 and other harsh environments, and its service life is more than twice that of aluminum alloy frames.
3. High Strength & Low Expansion Coefficient, Protecting PV Modules
The tensile strength of composite PV frames is 4-5 times that of aluminum alloy, and the axial strength is outstanding. Under the same load, the deformation of the module is smaller, which can effectively protect the battery sheet from hidden cracks. More importantly, its thermal expansion coefficient is close to that of PV glass, which avoids problems such as sealant damage and glass cracking caused by thermal expansion and contraction under large temperature differences, and greatly reduces the risk of module damage. Its thermal deformation temperature exceeds 230℃, and it can withstand extreme temperature differences from -40℃ to 85℃, which is suitable for high and cold areas such as Mohe, Heilongjiang and hot and dry areas such as Turpan, Xinjiang.
4. Green & Low-Carbon, Complying with International Environmental Standards
Against the background of global carbon neutrality, the low-carbon advantage of composite PV frames has become a core competitiveness. The carbon emission during production is only about 1/10 of that of aluminum alloy, and the production energy consumption is 1/5 of that of aluminum alloy frames, which fully meets the low-carbon environmental protection requirements of Europe, America and other regions. At the same time, the recyclability of composite materials is constantly improving. Through professional recycling technology, glass fiber and resin can be decomposed and reused, which greatly improves the utilization rate of resources and helps PV projects obtain carbon trading benefits. For foreign trade customers, this can effectively respond to the EU CBAM (Carbon Border Adjustment Mechanism) to be fully implemented in 2026 and avoid trade barriers.
5. Cost-Effective, Reducing the Whole Life Cycle Cost
Although the initial investment of composite PV frames is slightly higher than that of traditional aluminum alloy frames, the comprehensive cost advantage in the whole life cycle is obvious. The design service life of composite PV frames is 30-50 years, which is twice that of aluminum alloy frames (15-20 years), and it can perfectly match the service life of PV modules (more than 25 years), avoiding the cost of frame replacement during the operation of the power station. In addition, its maintenance cost is 60% lower than that of aluminum alloy frames, and the single set cost is 10%-20% lower than that of aluminum alloy frames. For large-scale PV projects, it can save a lot of operation and maintenance costs in the long run.
Practical Application Cases: Verifying the Value of Composite PV Frames Globally
Practice is the best proof. Our composite PV frames have been successfully applied to many large-scale PV projects at home and abroad, and have won unanimous recognition from customers with stable performance and excellent cost performance. Here are two typical cases for your reference.
Case 1: Huanxi Deep-Sea Floating PV Project (China)
Project Background: As the first deep-sea floating PV project in China, the project is located in the coastal area with annual average salt spray deposition of 750mg/m² and tidal range of more than 3 meters. The environment is harsh, and the corrosion resistance and impact resistance of PV frames are put forward high requirements.
Product Application: We provided customized polyurethane composite PV frames for the project. The frames adopt basalt fiber reinforced technology, with power of 640W and efficiency of 23%. They have passed 3000 hours of salt spray test without corrosion, and have excellent sealing performance to prevent seawater from seeping into the interior of the modules.
Application Effect: After one year of operation, the power attenuation of the PV modules is less than 1%, the output in 30 years is more than 90.3%, the integrity rate of the modules is 99.8%, which perfectly solves the corrosion problem of offshore PV and provides reliable guarantee for the development of blue energy.
Case 2: Huaneng Xinjiang Desert PV Power Station (China)
Project Background: The project is located in Kekedala City, Xinjiang, a desert area with annual average wind speed of 6.2m/s, maximum wind sand particle size of 0.5mm, and extreme temperature difference of 80℃ between day and night. It is a key project of the "desert, gobi and desert" wind-solar base.
Product Application: Our composite PV frames are used in the project, which are specially optimized for the desert environment. They have excellent wind sand resistance and high and low temperature resistance, and can withstand the impact of sand particles at wind speed of more than 10m/s without damage.
Application Effect: After 5 years of operation, the power attenuation of the modules is only 3.2%, the maintenance cost is reduced by 50% compared with the aluminum alloy frame project, and the stable operation of the power station is effectively guaranteed. It has verified the reliability of composite PV frames in extreme desert environments.
