In recent years, China photovoltaic industry has rapidly developed. What is the status and problems of the development of the solar photovoltaic industry in China? What solar PV industry chain including? Here we discuss on the solar PV industry chain related content, we hope to be able to help!
Under the background of the rising global energy demand, the high price of traditional energy and the continuous improvement of environmental concerns, renewable energy has been developing rapidly all over the world. The development of the industrial chain is closely related to the industrial outlook. It is the condition to promote the healthy development of China’s photovoltaic industry to correctly understand the development status and problems of China’s solar photovoltaic industry chain. So, what does the solar photovoltaic industry chain include?
The solar photovoltaic industry chain includes 6 links, such as silicon material, casting ingot (pull rod), slicing, battery chip, battery component, application system and so on. The upper reaches are silicon material and silicon chip, the middle reaches of the battery chip and the battery component, and the downstream is the application system link. From the global point of view, the number of enterprises involved in the 6 links of the industrial chain has increased in turn, and the industrial chain of the photovoltaic market is in the form of Pyramid.
The upstream of the solar photovoltaic industry chain is the production of silicon wafers and crystalline silicon materials for solar panels. This industry is a monopoly industry in China. It can also be divided into crystalline silicon production and crystalline silicon purification. Later processes include silicon wafer production, wafer cutting and silicon wafer making (improving the absorption of light by batteries).
The middle reaches of the solar photovoltaic industry chain is started by the production of crystalline silicon cells. It is the core step to process the crystalline silicon into the battery chip. In China, the application of crystalline silicon (single crystal, polycrystalline) photovoltaic components accounts for more than 95% of the market. Then, it is the production of battery components, the assembly of batteries into battery components, a labor intensive industry, and the tail end of the midstream of the photovoltaic industry chain.
The downstream of solar photovoltaic industry chain is the application of photovoltaic system, including centralized photovoltaic power plants, distributed household photovoltaic, photovoltaic street lamps, photovoltaic traffic lights, photovoltaic + and many other photovoltaic applications. This link is well known in the photovoltaic industry chain.
In the current development of the solar photovoltaic industry chain in midstream and downstream of the production of components used in the system of profit market competition has been reduced to a minimum, the future photovoltaic industry price if there are decline in space, there is relatively large profit only upstream of the crystal silicon production. But how the market develops, we need the regulation of the market. The production of upstream crystalline silicon is the foundation of photovoltaic industry chain. If we want to adjust the profit, we need to buffer the industry.
