The past decade has been a decade of rapid growth of the world's photovoltaics. At the beginning of the century, in the face of the energy crisis and environmental degradation, Europe, the United States and Japan took the lead in introducing PV application subsidies to cope with the country's growing energy demand. Then other countries, including developing countries, followed suit, so the world PV market was acquired. High-speed growth. The rapid rise of China's photovoltaic industry, through the development of scale, technology and industrial chain, has greatly promoted the decline of photovoltaic energy costs, and made significant contributions to the popularity of global photovoltaic applications. China's photovoltaic industry was almost a blank before 2001. Since 2004, the annual growth rate of China's PV industry has exceeded 100% for five consecutive years. Since 2007, China's photovoltaic cell production has ranked first in the world for four consecutive years. Last year, China's PV module production exceeded the global total output. 50%. There are dozens of PV companies listed overseas, with an annual output value of more than 300 billion yuan. At present, there are more than 500 PV companies across the country, with more than 300,000 people directly employed. In a short period of ten years, it has played an important role in the international market. The photovoltaic industry is the only strategic emerging industry and high-tech industry in China that has surpassed and led the world in a very short period of time with its own development advantages. The green energy industry is the industry with the highest level of internationalization. It is characterized by “a well-known brand blooms, a complete main industrial chain, complete supporting industries, and a world-leading comprehensive technology levelâ€. Due to the rise of China's PV industry, the cost of global PV products has dropped rapidly in the past decade, from the original US$6 per watt to the current US$1 per watt. The photovoltaic leveling energy cost (LCOE) has been associated with natural gas. The vision of a flat, affordable Internet is gradually being realized around the world. After ten years of rapid development, China's PV industry is also facing huge challenges: mainly because the speed of capacity expansion far exceeds the speed of market development. In 2010, the installed capacity of photovoltaic power generation in the world maintained a high-speed growth momentum. The newly installed capacity reached 18GW in the same year, an increase of 153% over the previous year. Last year, the growth rate of demand in the world PV market declined. According to the prediction of authoritative organizations, the installed capacity in 2011 was about 24GW, which was only about 33% higher than the previous year. At the same time, in recent years, the development of photovoltaic industry in various places has been surging, and the production capacity has expanded dramatically. At present, the production capacity of China's PV modules has reached 30GW (estimated at around 40GW worldwide). Based on 24GW of global installations last year, approximately 20GW components cannot be digested. Due to the mismatch between this capacity and market demand, and the fact that the industry is heavily dependent on the characteristics of the European and American markets, once the macro negative economic factors such as the European debt crisis are encountered, it will directly lead to a backlog of low-end domestic PV products, causing prices to fall. Compress the profit rate of Chinese industry. In this context, the price from the upstream crystalline silicon material to the midstream components has plummeted. According to authoritative data, component prices fell by more than 40% in 2011. At present, the European debt crisis has intensified, and the photovoltaic powers such as Germany and Italy have reduced their subsidies. As a result, the uncertainty of the world PV market has increased in 2012, which has a huge impact on China's photovoltaic industry, which is mainly exported to Europe. Therefore, the Chinese PV industry has to be adjusted and must be transformed, upgraded and integrated. On October 19 last year, seven solar cell module manufacturers in the United States filed a "double-reverse" investigation into Chinese PV companies to the US Department of Commerce and the US International Trade Commission. On March 2 this year, the US Department of Commerce will conduct a preliminary ruling. This has undoubtedly cast a shadow over the recovery of China's photovoltaic industry. In the long run, the fundamentals of the development of the photovoltaic industry have not changed, and the earth on which humans depend for survival is facing an increasingly serious energy crisis and environmental crisis. The increase in the world's population and the growth of the global economy are increasingly demanding energy. According to international authorities, the world's energy demand will reach 21.7 trillion kWh in 2015, if 5% of this comes from solar photovoltaics. This requires the installation of a 250 GW solar photovoltaic system to achieve, and according to the current scale and development trend of the photovoltaic industry, it is still far from meeting this demand. Traditional energy sources such as oil, natural gas, coal, and uranium mines are not renewable. This century will be exhausted, and environmental pollution will be large and hidden. The solar energy is the most abundant, ubiquitous and inexhaustible on earth. Energy, solar photovoltaic as a zero-emission, zero-consumption, clean, safe energy, has a great development prospects. It is precisely because the photovoltaic industry has a very positive impact on China's energy supply, energy security, energy conservation and emission reduction, and environmental protection. The state attaches great importance to the development of this emerging strategic industry, which was mentioned in the 12th Five-Year Energy Plan. We must vigorously develop photovoltaic applications. At the beginning of August last year, the National Development and Reform Commission issued a 1 yuan/kWh photovoltaic power grid benchmarking price policy, which immediately launched the domestic market demand in China. According to the latest data from the Energy Bureau, China’s new installations in 2011 reached 2.2GW220 for the first time. Ten thousand kilowatts. Recently, the Energy Bureau, the Ministry of Finance and other relevant departments have once again clarified the new "Golden Sun Plan". Although the subsidy standard has been adjusted from 8 yuan / watt to 7 yuan / watt, we think this will be greatly Promote the development of photovoltaic roof projects for commercial buildings in the eastern region. As the cost of photovoltaic power generation continues to decrease, the rapid development of market applications, especially in the domestic market, has made it a sustainable green growth point. With the arrival of the “1 yuan/kWh†era of photovoltaics, photovoltaics will become the “power saving and emission reduction†and the source and source of climate change. The combination of photovoltaic technology and traditional energy technologies can also realize the gradual adjustment of the future energy structure to achieve Steady and timely transition from fossil energy to renewable energy. Therefore, we should fully realize that photovoltaic power generation has become a reality, and the government should incorporate photovoltaic power generation technology into future energy development plans and roadmaps. It is recommended that the state formulate relevant laws, regulations, power policies, and financial policies to promote and implement photovoltaic power generation as soon as possible; formulate incentive and suppression policies to ensure the healthy development of the industry; improve scientific and technological research and development and innovation capabilities, and accelerate the promotion of new technologies and products. Speed; improve manufacturing level, lean production, specialized production, and accelerate the speed reduction; how the government cultivates and develops the photovoltaic industry should be a national strategy: strategic emerging industries.
