This industry, once crazed by investors, once gave birth to China's richest man; this industry, highly valued by governments of all countries, spends huge sums of money each year to provide subsidies to support development, and is hailed as the most promising industry. In 2007, China's output accounted for One third of the world; or this industry, there have been waves of bankruptcy in recent times, and even the former industry leaders can not escape the disaster! This is the photovoltaic industry. In just three years, it has experienced ups and downs between the boom of prosperity and the trough of recession. Many companies feel the taste of "burning oil from fire" to "biting ice". However, while domestic companies are still struggling to survive, a new message came from Wall Street: on the one hand, the stock prices of leading photovoltaic stocks in the United States have skyrocketed, and the most representative Sunpower (NASDAQ: SPWR) share price rose more than 300% this year; another On the one hand, Buffett, with $ 2.5 billion in acquisitions of photovoltaic power plants, and the world's most profitable company, "Apple", also invested in the photovoltaic industry. As the most effective capital market in the world, the rise in stock prices is because people are voting with funds. Buffett and Apple are competing to invest in the solar field during the trough of the industry. What does this mean? While the stock price is performing beautifully, the fundamentals of the industry are also changing. Emerging markets such as the United States and China are undergoing drastic changes. Industrial policies are being introduced intensively. Internet access and subsidy distribution are more certain and operable. The mid- and long-term planning of photovoltaic power plants has been greatly improved, and huge installation demand is on the verge. More importantly, as the photovoltaic conversion rate increases year by year and the cost decreases year by year, the power generation cost of the dominant companies will soon be the same as that of thermal power, and once this "critical point" is breached, the era of parity grid access is coming. PV power replaces traditional thermal power. The curtain of the moment is opened, and the structure of human energy consumption will change accordingly. The photovoltaic crisis is temporary, and the energy crisis is long-term. Let the blue sky replace coal, this is the dream of all mankind, let us look forward to, this dream can become a reality on the land of China as soon as possible! Review article The five phases of photovoltaic development dream into reality Looking back at the entire history of solar cell development, it can be roughly divided into five periods: budding period, climbing period, growth period, prosperity period, and recession period. Germination period (1839 ~ 1955): The landmark event of this period was the discovery of the "photovoltaic effect". In 1839, 19-year-old French Becquerel discovered the "photovoltaic effect" when doing a physical experiment. In 1954, Bell Laboratories successfully developed the first practical-value silicon solar cell. The New York Times called this breakthrough achievement "the ultimate result of the beginning of a new era in which infinite sunlight serves human civilization." Climbing period (1959 ~ 1994): The first monocrystalline silicon solar cell came out in 1959, and the solar cell was first connected to the grid in 1960. In 1978, the 100KW photovoltaic power plant was built in the United States, and the solar energy efficiency continued to increase. In 1980, the efficiency of monocrystalline silicon solar cells reached 20%, and polycrystalline silicon was 14.5%. Growth period (1994 ~ 2007): In the ten years from 1994 to 2004, global solar cell output increased 17 times, with an average growth rate of more than 50% in the past five years. After 2004, the solar cell market was fiercely competitive, and the leading patterns in Europe and Japan have been broken. Although the sales market is in Europe, the production center has shifted to Asia. In 2007, China's solar cell production accounted for about one-third of the world's total output, becoming the world's largest solar cell producer. Prosperity period (2010 ~ first half of 2011): Since the second half of 2010, the depressed demand of the global economic crisis has gradually been released, and the production capacity is in short supply. By the first half of 2011, a new round of prosperity has occurred in the global photovoltaic industry, and major manufacturers have expanded their production. Recession period (from the second half of 2011 to the end of 2012): In the post-financial crisis era, the blind expansion of production capacity has led to a serious overcapacity in the entire photovoltaic industry, and the price of photovoltaic products such as polysilicon has fallen in a "cliff style". Crisis Vicious competition VS Europe to cut the price of photovoltaic products fell into cold winter The follow-up effects of the financial crisis have a fatal impact on the photovoltaic industry. From 2010 to the first half of 2011, the demand suppressed by the financial crisis started, and the photovoltaic industry entered a new round of prosperity, but this prosperity period was due to the European debt crisis. The reduction of financial subsidies in various countries caused by the outbreak came to an abrupt halt. The development of the photovoltaic industry mainly depends on government subsidies. The reduction in subsidies directly affects the demand for installed capacity. Europe is the largest market in China's photovoltaic industry. Demand in the European market has shrunk and the domestic market has been unable to start. The disorderly expansion of the industry during the prosperous period eventually brewed the "bitter fruit" of overcapacity. Short-term supply shortages lead to massive expansion In the context of the global economic recovery in 2010, the previously suppressed demand was released, and the global photovoltaic industry showed a new round of growth. Statistics from the British research company IMSResearch showed that the global new photovoltaic installation capacity reached 17.5GW in 2010, compared with 2009 Compared with the annual 7.2GW increment, the growth rate is as high as 143%. The substantial increase in installed capacity has increased the demand for all links in the photovoltaic industry chain; the rapid growth in demand has also catalyzed the bull market in the entire photovoltaic industry from the second half of 2010 to the first half of 2011. First of all, in terms of polysilicon prices, driven by demand, since the second half of 2010, the price of polysilicon in the domestic spot market has risen from a minimum of about US $ 50 / kg to about US $ 100 / kg. Although the price has finally dropped, it has also Keep it at around US $ 80 / kg. Secondly, in the A-share capital market, new energy concept stocks such as Seiko Technology (002006), Leshan Power (600644), and Zhonghuan Shares (002129) were also heavily hyped by funds, and their stock prices rose several times. Behind the soaring product prices, it reflects a new round of prosperity in the industry. Due to the rapid growth of demand in the downstream international market and the relatively limited production capacity of domestic photovoltaic companies, domestic photovoltaic companies have begun to significantly expand their production capacity; and in the downstream photovoltaic cells and modules, similar to the development of upstream polysilicon, demand growth, This has enabled major enterprises to expand their production capacity in response to demand. Among them, the expansion rate of Wuxi Suntech, Tianwei Yingli, Hebei Jingao and other production capacity has reached more than 50%. European subsidies cut China's overcapacity The global economic recovery has released the suppressed demand of the photovoltaic industry, especially under the resonance of the installed demand in Germany and Italy. At the end of 2011, the global demand growth rate reached its highest peak. From the second half of 2010 to the first half of 2011, the photovoltaic industry experienced a big bull market. Since the cost of photovoltaic power generation is much higher than conventional energy, the development of the photovoltaic industry mainly depends on government subsidies. The European debt crisis is rampant. Among them, Germany and Italy, the world's major photovoltaic markets, have successively lowered the amount of photovoltaic subsidies, and the reduction in subsidies directly affects the increase in installed capacity. While 90% of China's solar photovoltaic products are exported, of which 80% of exports to Europe, the main countries include Germany, Italy, Switzerland and Belgium. The substantial reduction of subsidies in relevant countries has reduced the export space of domestic photovoltaic companies. Starting the domestic photovoltaic market demand has become the most urgent thing. Although after the financial crisis in 2008, China has introduced many policies to encourage the start of domestic demand, such as the Golden Sun demonstration project launched in 2009, but similar policy incentives have not been generated. The real effect, for example, during the implementation of the Golden Sun policy, has been caught in the game war between companies "drilling holes" and the government "patching". In fact, around the Golden Sun Demonstration Project, there are rumors of running projects, cheating subsidies, delaying work schedules, and subsequent charging, but in the end many photovoltaic projects have not been launched. On the other hand, the lack of domestic network access standards and the lack of product detection capabilities have also made photovoltaic power generation difficult to connect to the grid. This affects the upstream construction enthusiasm on the terminal and limits the start of domestic demand. What is an outdoor wireless access Point?
