Photovoltaic Status of Solar Photovoltaic Power Generation

China's photovoltaic power generation industry started in the 1970s and entered a period of stable development in the mid-1990s. The output of solar cells and modules has increased steadily year by year. After more than 30 years of hard work, it has ushered in a new stage of rapid development. Driven by national projects such as "Bright Project" and "Sending Electricity to the Countryside" and the world photovoltaic market, the photovoltaic power generation industry in China has developed rapidly.

By the end of 2007, the cumulative installed capacity of China's photovoltaic system reached 654.38+10,000 kilowatts (1000 MW), and there were more than 50 enterprises engaged in solar cell production, with a production capacity of 2.9 million kilowatts (2900MW) and an annual output of 1 188 MW, exceeding Japan and Europe. A complete industrial chain consisting of raw material production and photovoltaic system construction has been initially established, especially the production of polysilicon materials has made great progress, breaking through the annual output of 1000 tons, breaking through the bottleneck of raw material production of solar cells, laying the foundation for the large-scale development of photovoltaic power generation in China. 2007 is a year of rapid development of solar photovoltaic industry in China. Benefiting from the long-term interests of the solar energy industry, the entire photovoltaic industry has seen an unprecedented investment boom.

During the "Twelfth Five-Year Plan" period, the installed capacity of new solar photovoltaic power plants in China is about 6.5438+million kilowatts, and the installed capacity of solar thermal power generation is about 6.5438+million kilowatts. The average investment in photovoltaic power plants is estimated to be 6.5438+million yuan per kilowatt, and the total investment demand of distributed photovoltaic systems is about 2.5438+0.5 million yuan per kilowatt.

Although China is a big country in manufacturing solar energy products, our solar energy products are only used for export. In 20 10, the annual output of photovoltaic cells in global solar is160,000 kilowatts, of which the annual output in China is 10,000 kilowatts. By 20 10, the total installed capacity of global photovoltaic power generation will exceed 40 million kilowatts, and the main application markets are Germany, Spain, Japan and Italy, among which Germany will add 7 million kilowatts in 20 10.

However, China is rich in solar energy resources, and the land area suitable for solar power generation and the light receiving area of buildings are also large. Among them, the Qinghai-Tibet Plateau, the Loess Plateau, the Northern Hebei Plateau and the Inner Mongolia Plateau account for two-thirds of the country's land area, which has the potential for large-scale development and utilization of solar energy resources.

Solar energy is abundant and widely distributed, and it is the most potential renewable energy in 2 1 century. With the global energy shortage and environmental pollution becoming increasingly prominent, solar photovoltaic power generation has become a new industry that is widely concerned and focused on by all countries in the world because of its clean, safe, convenient and efficient characteristics.

In this context, the global photovoltaic power generation industry is growing rapidly, the industrial scale is expanding, and the product cost is declining. The photovoltaic power generation industry in China has also developed rapidly, and it has become one of the few industries in China that can participate in international competition at the same time and is expected to reach the international leading level. A number of well-known enterprises represented by Suntech Power, Yingli Green Energy, Jiangxi LDK, and Poly GCL Poly have emerged, as well as a number of industrial bases represented by Jiangsu, Hebei, Sichuan and Jiangxi. Therefore, in the past, the traditional practice of adjusting strategies and tactics by "year" seems to be somewhat inadequate and even passive in today's rapidly changing industries. Therefore, the management method that enterprises adjust their strategies on a monthly basis according to the latest development trend of the industry has attracted more and more attention from managers of many large enterprises, especially those of foreign-funded enterprises.

2065438+In July 2005, the solar photovoltaic power generation project of Baidu Cloud Computing (Yangquan) Center was successfully connected to the grid recently. This is the first application of solar photovoltaic power generation technology in domestic data centers. In the near future, solar photovoltaic power generation will occupy an important position in world energy consumption, which will not only replace some conventional energy sources, but also become the main body of world energy supply. It is estimated that by 2030, the proportion of renewable energy in the total energy structure will exceed 30%, and the proportion of solar photovoltaic power generation in the world's total power supply will exceed10%; By 2040, renewable energy will account for more than 50% of the total energy consumption, and solar photovoltaic power generation will account for more than 20% of the total electricity; By the end of 2 1 century, renewable energy will account for more than 80% of the energy structure, and solar power generation will account for more than 60%. These figures are enough to illustrate the development prospect of solar photovoltaic industry and its important strategic position in the energy field.

According to the medium and long-term development plan of renewable energy, China will strive to make the installed capacity of solar power generation reach 1.8GW (million kilowatts) by 2020 and 600GW (million kilowatts) by 2050. It is estimated that by 2050, China's renewable energy installed capacity will account for 25% of the national installed capacity, of which photovoltaic power generation installed capacity will account for 5%. In the next decade, the compound growth rate of solar energy installed capacity in China will reach more than 25%.
