National "Twelfth Five-Year Plan"...
In recent years, with the increasingly prominent environmental issues, the concept of green development has gradually penetrated the hearts of the people. The development direction of the global economy and navigation standards have turned to a low-carbon economy, and the solar photovoltaic industry has received attention from all countries in the world. The National 12th Five-Year Plan outlines that it is necessary to vigorously develop strategic emerging industries such as energy conservation, environmental protection and new energy. The new energy industry will focus on solar thermal utilization, photovoltaic thermal power generation, and biomass energy. Thanks to the attention paid by all parties in recent years to the development of solar photovoltaic industry, China has formed a complete solar photovoltaic industry chain. It is understood that with the large-scale application and rapid development of domestic solar photovoltaic power generation, the upstream large-scale industrial production and application technology of polysilicon has become increasingly mature, especially from the domestic and global existing production technology level, the entire The polysilicon production industry chain and the closed operation within the system are close to zero emission levels.
(1) The development of China's photovoltaic industry has broad prospects, and the transformation and upgrading of new energy is a good opportunity.
The world's conventional energy supply shortage crisis is becoming more and more serious. The large-scale development and utilization of fossil energy has become one of the main causes of natural environmental pollution and the deterioration of human living environment. Searching for emerging energy has become a hot issue in the world. Among various new energy sources, solar photovoltaic power generation has the advantages of pollution-free, sustainable, large total, wide distribution, and diverse application forms, and has been highly valued by countries all over the world.
China's photovoltaic industry has a good development foundation in terms of manufacturing level, industrial system, technology research and development, etc. The domestic and international market prospects are generally optimistic. As long as we seize the development opportunities and accelerate the transformation and upgrading, we will usher in a broader development space.
(2) The photovoltaic industry, policies and markets need to be strengthened and the external market dependence has a certain impact.
At present, the domestic policy system supporting photovoltaic applications and the long-term interactive mechanism to promote the sustainable development of photovoltaic power generation are being established. Most of the solar cell products are exported to overseas markets. The industrial development is greatly affected by the financial crisis and overseas market changes, and the dependence on external markets. Too high is not conducive to sustained and healthy development.
From a global perspective, it will take some time for photovoltaic power generation to be competitive in terms of price. The recent growth momentum of solar cell demand mainly comes from the government's policy support and price subsidies for the photovoltaic industry; the continued growth of the market will also promote the scale of the industry. Expansion and product cost decline, thereby promoting the healthy development of the photovoltaic industry.
(3) Faced with the severe challenges of international economic turmoil and trade protection, the state needs to strengthen supervision over the photovoltaic market.
The international capital is also generally optimistic about the photovoltaic industry: on the one hand, many large enterprises in the photovoltaic industry have announced new investment plans, and continue to expand production scale; on the other hand, other areas such as semiconductor companies, display companies carry a variety of market capital is or Will enter the photovoltaic industry.
In recent years, there has been a turbulent situation in the global economic development. Some countries have adjusted their new energy policies and related subsidies have been lowered, which has a great impact on the development of China's photovoltaic industry. At the same time, there have been many trade disputes against China's photovoltaic industry in Europe and the United States. Similar disputes will still occur in the future. The main reasons are as follows: First, China's solar cell cost advantage is obvious, causing pressure on foreign products; second, the domestic PV market is not yet big. The scale starts, the products are mainly exported, which may cause dumping doubts; the third is that China's relevant standard system is still not perfect, and there are problems such as uneven product quality levels.
(4) Rapid evolution of new technologies and technologies, and increasing international competition
The global photovoltaic industry technology development is changing with each passing day: the conversion efficiency of crystalline silicon cells is increasing by one percentage point annually; the technical level of thin-film batteries is continuously improving; the emerging technologies such as nano-material batteries are developing rapidly; the production and testing equipment for solar cells are constantly upgrading. The domestic PV industry still has a large gap in many aspects, and the international competition pressure is constantly escalating: the key technology of polysilicon still lags behind the international advanced level. The high-grade equipment for the production of crystalline silicon cells still needs to be imported, and the process and equipment level of the thin-film battery are obviously backward.
(5) Market application continues to expand, reducing costs is still an industry theme
The application of solar photovoltaic market will show a wide range of fields and diversified trends. Photovoltaic products that meet various needs will continue to emerge. In addition to large-scale grid-connected photovoltaic power plants, photovoltaic power generation systems, small-scale photovoltaic systems, and off-grid photovoltaic systems combined with buildings Etc. will also rise rapidly. The cost of solar cells and photovoltaic systems continues to decline and approach the cost of conventional power generation. It will continue to be the theme of the development of the photovoltaic industry. From silicon materials to components and supporting components, the market pressure of rapid price reduction will be faced, and solar cells will continue to be highly efficient. Development in low cost direction.
