The rise of photovoltaic power generation has led to the rapid development of peripheral industries, such as fiberglass polyurethane PV module frames. Compared with the traditional aluminum and metal PV frames, FRP polyurethane profiles used as PV module frames have the following advantages.
1, polyurethane composite material has excellent mechanical properties, its axial tensile strength reaches more than 7 times that of traditional aluminum alloy material.
2, has a strong resistance to salt spray and chemical corrosion.
3, has a high volume resistivity, photovoltaic modules using polyurethane frame encapsulation, greatly reducing the possibility of forming leakage circuits, which helps reduce the generation of PID potential-induced attenuation phenomenon. The power generation efficiency of the panel is improved.
4、Urethane frame profile and coating are used together, which greatly increases the weather resistance of the frame and has very low VOC emission.
