Development Status and Trend Analysis of China's Solar Energy Industry

Word:[Big][Middle][Small] QR Code 2018/6/14     Viewed:    
China is a large wafer manufacturing country. In 2017, China's wafer production was approximately 18.8 billion wafers, equivalent to 87.6 GW, an increase of 39% year-on-year, accounting for 83% of global wafer production, of which single crystal wafer production was approximately 6 billion. sheet.

So what promotes the development of China's silicon wafer industry, some of the relevant factors are listed below:

I. Energy crisis forces humans to look for alternative energy sources

According to the analysis by the World Energy Agency, based on the currently proven fossil energy reserves and mining speed, the remaining remaining recoverable life of the global oil is only 45 years, and the remaining remaining recoverable life of the country is 15 years. The remaining remaining recoverable life of the global natural gas is 61 years. , The remaining domestic mineable life is 30 years; the global remaining coal mineable life is 230 years, the domestic remaining mineable life is 81 years; the global remaining uranium mineable life is 71 years, and the domestic remaining mineable life is 50 years. The limited reserves of traditional fossil energy forces mankind to accelerate the pace of finding alternative renewable energy sources.

The reserves of China's primary energy resources are far below the world's average level. The renewable energy replacement situation in China is more severe and urgent than in other countries in the world. Solar energy resources are not reduced due to use, and have no adverse impact on the environment. Vigorously developing the solar photovoltaic industry is an important measure and way to solve the current contradiction between energy supply and demand in China and adjust the energy structure. At the same time, vigorously developing the solar photovoltaic industry is also a strategic choice to cope with climate change and achieve sustainable energy development in the future, so it is of great significance.

The importance of environmental protection and sustainable development

Excessive exploitation and use of fossil energy has caused huge pollution and damage to the global environment on which human beings depend. The large amount of carbon dioxide emissions has led to the global greenhouse effect, which has led to the melting of polar glaciers and the rise of sea levels; large amounts of industrial exhaust and automobile exhausts have caused serious deterioration in air quality and caused the epidemic of respiratory diseases. Human beings have realized the importance of protecting the environment and sustainable development. At the same time, solar energy has received extensive attention and application due to its renewable nature and environmental friendliness. Governments of various countries have actively adopted various measures to encourage and develop the solar energy industry, increase investment in research and development, and advance the pace of solar photovoltaic technology. Significantly accelerated, the scale of the industry expanded rapidly, market demand continued to rise, and economic, environmental and social benefits became increasingly apparent.

    Government incentives

Affected by the limited pressure of fossil energy and the pressure of environmental protection, renewable energy has gradually become an important part of the energy strategic planning of various countries. Among them, the photovoltaic power generation industry is an important part of renewable energy in various countries. Since the Renewable Energy Law, governments of various countries have successively introduced a series of supportive policies to promote the development of the solar photovoltaic industry. These supportive policies have promoted the rapid development of the solar photovoltaic industry in the past few years and will also provide good development opportunities for the solar photovoltaic industry in the future. The Chinese government has also issued a number of policies and plans, such as "Implementation Opinions on Accelerating the Application of Solar Photovoltaic Buildings", "Interim Measures on the Management of Financial Subsidy Funds for the Golden Sun Demonstration Project", and "National Development and Reform Commission's Policy on Improving the On-grid Price of Solar Photovoltaic Power Notice "," Twelfth Five-Year Plan "for solar power development," Thirteenth Five-year Plan for power development ", etc. These policies and plans have effectively promoted the development of China's photovoltaic power generation industry.

24. Cost advantage makes solar cell manufacturing shift to mainland China

Because China's advantages in labor costs and test packaging are becoming more and more obvious, the manufacturing of global solar cell end products is gradually shifting to China. In order to reduce costs, end-product manufacturers generally adopt the principle of purchasing nearby and assembling nearby, and try to purchase parts locally. Therefore, the migration of the downstream manufacturing industry will also have a direct impact on the layout of the silicon rod industry in the midstream. The increase in China's solar cell output will increase the demand for domestic solar ingot wafers, which will in turn drive the booming development of the entire solar ingot wafer industry.

V. China has superior resource conditions for developing solar energy

In China's vast land, there are abundant solar energy resources. China is located in the northern hemisphere. The distance between the north and the south and the distance between the east and west are more than 5000 kilometers. Two-thirds of the land area is more than 2200 hours of annual sunshine hours. In good areas, the potential for solar resource development and utilization is very broad. China has abundant silicon resources, which can provide raw material support for vigorously developing the solar photovoltaic industry. Utilizing the desert and the new housing construction area every year can provide a lot of marginal land and roof and wall areas for the development of solar photovoltaic power plants.
