China is a large silicon wafer manufacturing country. In 2017, China’s silicon wafer output was about 18.8 billion pieces, equivalent to 87.6GW, a year-on-year increase of 39%, accounting for about 83% of the global silicon wafer output, of which the output of monocrystalline silicon wafers was about 6 billion. piece.
So what promotes the development of China's silicon wafer industry, and some relevant influencing factors are listed below:
1. The energy crisis forces mankind to look for alternative energy sources
According to the analysis of the World Energy Agency, based on the current proven fossil energy reserves and mining speed, the remaining recoverable life of global oil is only 45 years, and the remaining recoverable life of domestic natural gas is 15 years; the remaining recoverable life of global natural gas is 61 years The remaining mineable life in China is 30 years; the remaining mineable life of global coal is 230 years, and the remaining mineable life in China is 81 years; the remaining mineable life of uranium in the world is 71 years, and the remaining mineable life in China is 50 years. The limited reserves of traditional fossil energy force humans to accelerate the pace of finding alternative renewable energy.
The reserves of China's primary energy resources are far below the world's average level, and the replacement situation of China's renewable energy is more severe and urgent than other countries in the world. Solar energy resources will not be 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 China's energy supply and demand and adjust the energy structure. At the same time, vigorously developing the solar photovoltaic industry is also a strategic choice to address climate change and achieve sustainable energy development in the future, so it is of great significance.
2. The importance of environmental protection and sustainable development
The excessive exploitation and use of fossil energy has caused enormous pollution and damage to the earth environment on which human beings depend. The massive emission of carbon dioxide has led to the global greenhouse effect, which in turn has triggered the melting of polar glaciers and the rise of sea levels; the massive emissions of industrial waste gas and vehicle exhaust have led to serious deterioration of air quality and the prevalence of respiratory diseases. Human beings have realized the importance of protecting the environment and sustainable development. At the same time, solar energy has been widely concerned and applied due to its renewability and environmental friendliness. Governments of various countries actively take various measures to encourage and develop the solar energy industry, increase investment in research and development, and make the pace of solar photovoltaic technology progress Significantly accelerated, the rapid expansion of the industrial scale, rising market demand, economic benefits, environmental benefits and social benefits are becoming more and more obvious.
3. Government Incentive Policies
Affected by the dual pressures of limited fossil energy and 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 April 2000, Germany passed the " Since the Renewable Energy Law, governments of various countries have successively issued a series of support policies to promote the development of the solar photovoltaic industry. These support policies have promoted the rapid development of the solar photovoltaic field in the past few years and will also provide good development opportunities for the solar photovoltaic field in the future. The Chinese government has also issued many policies and plans, such as "Implementation Opinions on Accelerating the Application of Solar Photovoltaic Buildings", "Interim Measures for the Management of Financial Subsidy Funds for the Golden Sun Demonstration Project", "National Development and Reform Commission's Policy on Improving Solar Photovoltaic Power Generation Feed-in Tariffs" "Notice", "The Twelfth Five-Year Plan for Solar Power Development", "The Thirteenth Five-Year Plan for Electric Power Development", etc. These policies and plans have effectively promoted the development of China's photovoltaic power generation industry.
4. The cost advantage makes the solar cell manufacturing industry transfer to mainland China
Due to China's increasingly obvious advantages in labor costs and testing and packaging, the manufacturing of global solar cell terminal products is also gradually shifting to China. For the sake of cost reduction, terminal product manufacturers generally adopt the principle of purchasing 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 midstream silicon rod and wafer industry. The increase in China's solar cell production will increase the demand for domestic solar silicon rods and wafers, which in turn will drive the vigorous development of the entire solar silicon rods and wafers industry.
5. 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, with a distance of more than 5,000 kilometers from north to south and from east to west. Two-thirds of the country’s land area has annual sunshine hours of more than 2,200 hours, and the total annual solar radiation is greater than 5,000 megajoules per square meter. In a good area, the potential for the development and utilization of solar energy resources is very broad. China is rich in silicon resources, which can provide raw material support for vigorously developing the solar photovoltaic industry. Utilizing the desert and the newly added housing construction area each year, a large amount of marginal land and roof and wall areas can be provided for the development of solar photovoltaic power plants
