Solar energy new development must break through the obstacles1

Although China is a nation of energy consumption, but the energy problem has not only is China a country are faced with the problem, has become a worldwide problem. Then, people at the same time, the eyes are aimed at the clean, green, the outer layer of the renewable resources & ndash; — Solar energy, so, at that time, the development and utilization of solar energy has become an important part of national energy system. However, the development of solar energy after all these years, although the solar street light, solar water heater has been into people's lives, such as, however, to make a reality of the available energy of sunlight, but is still a global scientists puzzled subject, especially for China.

not of course is that China is to solve the problem of energy and the environment of the development of the contradiction, the solar energy is a very good alternative sources of energy, it is not only China's future energy sources, is also the future of the world energy. At present, China has reached 2. 5 billion tons annual consumption of coal, and we must control the years of coal within the 3 billion tons, in order to reduce damage to the environment. At present, countries in developing the energy such as wind, water and electricity, according to the scientific measurement, if all the wind and hydropower potential developed, are still difficult to meet the future energy needs. Therefore, the solar energy with its clean persistence has incomparable advantages. The use of solar power of the Chinese in three aspects: one is the construction of solar photovoltaic power station, the solution to remote areas the population of electricity, from 2002 to 2003 by the government to invest 5 billion yuan to build solar energy, solve the problem of the township, 1000 nearly 2 million people use electricity. 2 it is combined with large buildings in cities build a distributed grid of small solar power plant; Three is to use the relatively rich resources of desert, gobi in the west and the construction of a batch of solar power plants.

solar has a very worthy of study energy price system, the key is the price of silicon raw material. Silicon raw material price of solar energy lamp production more than a third of the total cost of nearly half, it costs a lot of man-made factor in pushing up of the market. In 2000, the price of silicon to $20 per kilogram, has now reached $400 per kilogram. Silicon raw material supply from 10 to 20 times the rise in the price of it. Recently all over the world including China are at silicon raw material production factory. Economies of scale may also affect the cost, if the silicon can costs have fallen sharply, will lead to the costs of solar has fallen dramatically.

so, you can say that, silicon material has become the bottleneck for the further development of the solar industry, only on the existing technology, vigorously reduce the price of silicon materials, solar products prices will reduce accordingly, to further expand the market.
