Aluminum alloys are mainly used in solar photovoltaic frames and solar photovoltaic brackets in the photovoltaic field. The solar photovoltaic frame and bracket mainly play the role of fixing and sealing the solar cell module, enhancing the strength of the module, and facilitating transportation and installation. Their performance will affect the life of the solar cell module. Of course, in the photovoltaic frame, there are also several other photovoltaic frames, such as: steel frame, polymer material frame and glass fiber reinforced plastic frame, etc. However, due to the light weight, strong corrosion resistance, easy forming, high strength, easy cutting and Due to the characteristics of processing and recyclability, it is more commonly used in solar frames at present.

The domestic photovoltaic industry started late but showed a momentum of rapid development. In 2002, my country's photovoltaic industry began to take off. During the "Tenth Five-Year Plan" period, my country has successively passed the "National High-Tech Research and Development Plan" and "Science and Technology Research" plans in the research and development of photovoltaic power generation technology, which has shortened the gap between the photovoltaic power generation manufacturing industry and the international level. In recent years, photovoltaic technology has been iteratively updated, and product development has been ups and downs. Through the continuous efforts of photovoltaic people, China's photovoltaics have reached the world level. On October 24, 2020, the "Opinions of the Central Committee of the Communist Party of China and the State Council on Completely, Accurately and Comprehensively Implementing the New Development Concept and Doing a Good Job in Carbon Peaking and Carbon Neutralization" was released. The opinions clearly achieve carbon peaking and carbon neutrality goals, and mention that by 2030, the proportion of non-fossil energy consumption will reach about 25%, and the total installed capacity of wind power and solar power generation will reach more than 1.2 billion kilowatts. As the main force of the dual-carbon goal, photovoltaics should start from themselves and contribute to the dual-carbon goal.

In the course of photovoltaic development, improving module efficiency and reducing module cost have always been the two goals of photovoltaic people. Through years of research, the efficiency of photovoltaic cells has been continuously improved. At the same time, major mainstream manufacturers have reduced the cost of the module side through the optimization of different process combinations and auxiliary material solutions.

Photovoltaic aluminum alloy frame has always been one of the very important auxiliary materials of photovoltaic modules. Although photovoltaic has experienced the era of frameless double-glass modules, due to frequent problems at the application end of power plants, a large number of customer complaints and compensation have been caused. Time has proved that aluminum alloy frames are one of the indispensable auxiliary materials for photovoltaic modules.
