1.1 Trends in Green Energy Development

Amid the escalating challenges of global warming and energy shortages, the development of green energy is advancing swiftly. Across the globe, nations are introducing policies to promote the green transition of energy. The European Union aims for renewables to account for 32% of energy consumption by 2030, vigorously expanding wind and solar power. Germany is actively pursuing its "energy transition" strategy, phasing out nuclear power and increasing investment in renewables. The Biden administration in the U.S. has proposed a series of green energy initiatives, targeting carbon-free power generation by 2035. As a major energy producer and consumer, China has set carbon peak and carbon neutrality goals, driving the growth of photovoltaic, wind, and other green energy industries. Green energy is increasingly prominent in the energy mix, emerging as a pivotal direction in global energy transformation. It holds significant importance for ensuring energy security, addressing climate change, and achieving sustainable development.

New infrastructure has accelerated the development of the green energy industry. In terms of information infrastructure, the application of technologies such as 5G and big data centers has expedited the construction of smart grids, enhancing the operational efficiency of power systems and the capacity to integrate renewable energy. In the realm of integrated infrastructure, the construction of new energy vehicle facilities like charging stations has promoted the widespread adoption of electric vehicles, reduced reliance on traditional fossil fuels, and fostered the coordinated development of new energy vehicles and renewable energy sources. Regarding innovative infrastructure, continuous support for new energy technology R&D has driven breakthroughs in key technologies such as photovoltaic modules and wind power generation, lowering the costs of green energy and improving its market competitiveness, thereby laying a solid foundation for the large-scale development of the green energy industry.

2、 Characteristics of Carbon Fiber Photovoltaic Module Frame

2.1 Advantages of Carbon Fiber Materials

Carbon fiber materials have many excellent properties. It has a lightweight texture and a density of only about 1/4 of steel, but it has strength comparable to or even higher than steel, with a tensile strength of over 3500MPa, 7-9 times that of steel. Its modulus is also extremely high, which means it can maintain good shape stability when subjected to external forces. Carbon fiber also has excellent corrosion resistance, maintaining stable performance in various corrosive environments such as acid, alkali, salt, etc., and its service life far exceeds that of traditional materials.

The advantage of carbon fiber frame is extremely obvious in photovoltaic modules. The lightweight characteristics can significantly reduce the weight of photovoltaic modules, facilitate transportation and installation, reduce transportation costs and installation difficulties, and improve installation efficiency. The high-strength characteristics make the components stable and durable in various complex environments, with stronger resistance to wind pressure, snow accumulation, and other abilities, extending the service life of the components. The corrosion resistance ensures the stable operation of the components in harsh environments such as seaside and saline alkali land, expanding the application scenarios of photovoltaic modules.

2.2 Energy saving and Environmental Protection Characteristics Reflected

The frame of carbon fiber photovoltaic modules exhibits excellent energy-saving and environmental protection characteristics during production and use.

In the production process, although the production process of carbon fiber materials is complex, compared to traditional metal frames, its production process can reduce energy consumption and carbon emissions. The production of metal frames requires high-temperature melting, which consumes a large amount of electricity, while the production of carbon fiber frames is relatively energy-saving, and with the advancement of technology, the energy consumption of carbon fiber production is continuously decreasing.

During use, the lightweight nature of the carbon fiber photovoltaic module frame reduces the overall weight of the module and lowers energy consumption during transportation and installation. Due to its high strength and good stability, the service life of the components is extended, reducing resource waste and carbon emissions caused by frequent component replacement. The carbon fiber module frame can also maintain efficient power generation performance of photovoltaic modules in various harsh environments, improve energy conversion efficiency, further reduce the carbon emission intensity per unit of electricity, and contribute an important force to the development of green energy.

3、 Practice of reducing costs and increasing efficiency

3.1 Ways to Reduce Costs

In terms of materials, optimizing the carbon fiber production process can improve the quality of raw silk and carbon fiber yield, and reduce material loss. Replacing imported raw silk with domestically produced raw silk can also reduce the cost of carbon fiber. High performance carbon fiber and low-cost carbon fiber can also be mixed in proportion using a mixing ratio to ensure frame performance while controlling costs.

In production, continuously improve the production process of carbon fiber frames to enhance production efficiency and yield. If higher automation level production equipment is adopted, it can reduce manual operation errors and lower the scrap rate. Optimize production processes, shorten production cycles, and reduce energy consumption and production costs.

In the transportation process, due to the lightweight of carbon fiber frames, more components can be transported under the same transportation conditions, reducing unit transportation costs. Lightweight components are also convenient for loading and unloading, reducing losses during transportation and further saving costs.

3.2 Efficiency Improvement Performance

The high strength and stability of carbon fiber photovoltaic module frames enable the modules to maintain good condition in complex outdoor environments, reducing maintenance frequency and costs caused by frame deformation and other issues. Its excellent corrosion resistance allows the components to operate stably for a long time even in harsh environments such as seaside and saline alkali land, reducing maintenance frequency and difficulty.

The lightweight characteristics of carbon fiber frames make the installation of photovoltaic systems more convenient and fast, improving installation efficiency. Installation personnel can easily transport and install components, shorten the construction period, and enable the photovoltaic system to be put into operation and generate electricity faster.

Carbon fiber frame can also improve the power generation efficiency of photovoltaic modules. Its low thermal expansion coefficient can reduce the stress deformation of components caused by temperature changes, maintain good electrical contact between the battery cells, and improve the photoelectric conversion efficiency. Moreover, carbon fiber frames are not easily affected by electromagnetic interference, which can reduce energy loss and enable photovoltaic systems to output more electricity, bringing higher economic benefits to users.

In the wave of green energy new infrastructure, the development prospects of carbon fiber photovoltaic module frames are very broad. With the acceleration of global energy transition, the photovoltaic industry will continue to develop rapidly, and the demand for high-performance photovoltaic modules will also continue to grow. Carbon fiber photovoltaic module frames will become increasingly popular in the market due to their advantages of energy conservation, environmental protection, cost reduction, and efficiency improvement.

From a technical perspective, with the continuous advancement of carbon fiber production technology and the gradual reduction of production costs, the cost of carbon fiber photovoltaic module frames will also further decrease, which will greatly enhance its market competitiveness. From a policy perspective, countries have continuously increased their support for green energy and introduced a series of preferential policies, which will provide a favorable policy environment for the application of carbon fiber photovoltaic module frames. From the perspective of market demand, carbon fiber photovoltaic module frames will not only be widely used in new photovoltaic projects, but also have huge market potential in the renovation and upgrading of old photovoltaic projects.
