The development of photovoltaic industry for Fujian

No need to lay cable, do not consume electricity, when night falls, the street lights will automatically illuminate - in many parts of our country, this solar street lights have been civilians.

The day before, the reporter was informed that held in Fujian province Nanan city of Fujian Province in 2009 PV project matchmaking, the PV industry has been "too high to be reached," is gradually entered the daily life.

Advantage of resources

Fujian silicon mine is rich in resources, production accounts for about 9.4%, 6.7% of the world, is one of the world's highest purity grade, mining area, which provides sufficient resources for local low cost of acquiring polysilicon raw material.

In recent years, Fujian province also attaches great importance to the development of photovoltaic industry. April 2007, "opinions to promote LED and solar photovoltaic industry development in Fujian province (2007~2010)" promulgated, the provinces have topped.

"Opinions" put forward nine aspects of support measures, including promoting the public application and reward innovation, promotion of LED and photovoltaic products, the implementation of preferential tax policies on the industry and electricity, the province encouraged the production of LED and photovoltaic products, the establishment of public technology service platform.

Not long ago, the Fujian provincial government held a special meeting to promote the work of photovoltaic industry projects, requires close coordination of various departments, starting with the support of the prospects for the development of enterprises, to provide good service, to accelerate the development of solar photovoltaic industry.

Currently, Fujian solar cell module capacity of 500 mw. Data show that Fujian LED and Photovoltaic Industry Park (base) construction has entered a climax, over 150 enterprises, the output value of over $10 billion. The province's 12 professional industrial park, located in Fuzhou, Xiamen, Quanzhou and Yunxiao, Huaan, Changting and other places, the regional photovoltaic industry agglomeration effect. Fujian PV industry chain is gradually improved, the scale of development has leapt to the forefront of the country.

Fujian is an important base for the development of photovoltaic industry in Quanzhou. To the end of 2008, Quanzhou photovoltaic industry and related industry output value of about 1 billion 500 million yuan, has formed from silicon ore mining and rough machining of silicon and polysilicon purification production to pull monocrystalline or polycrystalline silicon cast into slices, and then to the crystal silicon solar cell and battery components production of crystalline silicon solar cell industry chain.

Nanan Sanjing Electric Power Co. Ltd., Fujian Sun Jun stone Energy Co. Ltd., Taiwan funded enterprises, Jin Baoli Chuanghui company and a number of photovoltaic enterprises has put into operation...... At present, there are more than and 40 photoelectric enterprises in Quanzhou, forming a solid industrial base, as a new force in the development of the west coast of the photovoltaic industry cluster.

According to Fujian Province, "11th Five-Year" plan, the province will increase the proportion of solar photovoltaic power generation in the energy structure, the high purity silicon production reached 3000 tons, 150 MW of solar modules, solar photovoltaic power generation capacity of 5 MW solar downstream products output value of 10 billion yuan, the total value of 15 billion yuan to 20 billion yuan of photovoltaic industry.

Technology to improve the way to lower costs

The production of solar grade polysilicon is mainly using chemical method, also known as "SIEMENS"". The method of large investment, complex technology, the core technology in the hands of the United States, Japan, Germany, 3 countries in the hands of the company, the formation of technical blockade, market monopoly. At the same time in the photovoltaic industry demand for polysilicon surge, resulting in the shortage of polysilicon materials, the price of $40 / kg from 2003 up to now 150 dollars / kg, the first half of last year had reached the highest $500 / kg. In the cost of solar cells, the cost of polysilicon accounted for more than 50%. Therefore, to solve the shortage of polysilicon materials, reduce production costs, is the basis for the promotion and application of solar cells and bottlenecks.

It is one of the most important methods to purify the solar grade silicon material by physical metallurgy, which is expected to break through the tight supply of silicon material and reduce the cost of solar cells. Fujian province took the lead in carrying out the research on the purification of solar grade silicon materials by physical metallurgical method, and the results are remarkable.

According to statistics, there are more than and 70 kinds of industrial silicon smelting enterprises in Fujian, more than 3000KW of the refining furnace, with an annual output of 80 thousand to 100 thousand tons of industrial silicon. From the late 90s of last century, the relevant enterprises, scientific research units to explore the use of metallurgical extraction of high purity silicon from silicon.

In 2007, the purification technology for solar grade silicon crystal silicon products physical method of independent research and development company, broke through the silicon material supply constraints, form the largest advantage of Nanan optoelectronic information industry. In recent years, absorbing the photovoltaic industry upstream and downstream projects to gather Nanan, initially formed a relatively complete industrial chain of photovoltaic photovoltaic project: 8 floor, 800 million yuan of investment, output will reach 7 billion yuan, will soon have 15 projects, covering the production of photovoltaic, electronic, optoelectronic applications and other products LED.

It is understood that the chemical method of silicon solar grade silicon material physical method is compared with the existing monopoly of foreign technology, has three major advantages: first, low power consumption, can greatly reduce the production cost; two is the short construction period, the one-time investment cost is low, can be used for mass production; three is the "three wastes", and easy to handle.

Government to promote indispensable

Solar photovoltaic industry outlook is good, but many companies are still struggling in advance.

Polysilicon belongs to the upstream industry of solar photovoltaic. With the spread of the international financial crisis, the global market demand is reduced, polysilicon countries
