China Report Hall Network News, solar panels are the core part of my country's solar power generation system, and as a major component country, it has laid a foundation for the market development of solar panels. In the past two years, affected by the epidemic, the development of solar panels has been hindered to a certain extent, and both production and sales have declined.
Solar panel (also known as solar cell module) is an assembly of multiple solar cells assembled by assembly, which is the core part of the solar power generation system and the most important part of the solar power generation system.
Development Status of Solar Panel Industry
my country is a big producer of modules, and it has an absolute advantage in terms of the global structure. Among the world's top ten module manufacturers in 2019, Chinese companies account for a large proportion. From the perspective of the domestic situation, the industrial concentration of my country's module industry is relatively high, among which leading enterprises include Jinko, Trina, GCL Integrated, Canadian Solar, JA Solar, and Hanwha. The output of foreign manufacturers is smaller than that of domestic manufacturers, and China's cell production capacity is the world's leading.
The market analysis of the solar panel industry shows that in the first half of 2020, the development of domestic solar panels has been hindered, mainly due to the impact of the new crown epidemic. The resumption of work and production of various enterprises has been affected to a certain extent, and the production and sales of products have a certain degree slide. In the first half of 2020, the market size of the domestic solar panel industry was approximately 181.7 billion yuan, a decrease of 4.12% from the same period in 2019.

Uncoordinated development of the solar panel industry chain
The market analysis of the solar panel industry shows that at present, China has become an important production base for solar photovoltaic power generation, and has gradually formed industries in high-purity polysilicon manufacturing, silicon ingot, silicon wafer production, solar cell manufacturing, photovoltaic module packaging, and photovoltaic system applications. chain, resulting in a number of leading international large-scale solar cell manufacturers. Although the industrial scale of China's solar panel industry currently ranks first in the world, the development of the industrial chain is uncoordinated. Some industries are oversupplied, and some industries are undersupplied.
Crystalline silicon materials (including polycrystalline silicon and monocrystalline silicon) are the most important photovoltaic materials, with a market share of more than 90%, and will still be the mainstream material of solar cells for a long period of time in the future. The production technology of the solar panel industry has long been in the hands of 10 factories of 7 companies in 3 countries including the United States, Japan, and Germany, forming a situation of technology blockade and market monopoly. The demand for polysilicon mainly comes from semiconductors and solar cells. According to different purity requirements, it is divided into electronic grade and solar grade. Among them, about 55% are used for electronic-grade polysilicon, and 45% are used for solar-grade polysilicon.
In general, solar panels play an important role in the solar energy industry. With the continuous advancement of related technologies, solar panels are gradually applied in the manufacturing of photovoltaic modules and solar cells in the industrial chain.
