The rising international oil prices and the deteriorating environment have made renewable energy an unprecedented priority, and the photovoltaic industry as a leader in the field of renewable energy, the development of the Chinese market in the past two years is in full swing.
At the seminar on trade standards for renewable energy and energy-saving lighting systems held in Pudong on June 23, Gao Hu, deputy director of the National Development and Reform Commission's Renewable Energy Development Center, revealed that as of 2007, the cumulative installed capacity of photovoltaic power generation in China has reached 100,000 kilowatts.
Wang Sicheng, executive director of the China Solar Energy Society, said: In 2007, China has already occupied six of the world's top 16 solar cell companies. According to the China Solar Energy Association, the domestic solar cell production in 2007 was about 1,180 megawatts, while the production in Europe, Japan and the United States was 1062, 920 and 266 megawatts respectively. China has become the world's number one solar cell.
As the photovoltaic industry has been dying in the past two years, its standardization process has lagged far behind the pace of industrial development.
Li Xianai, director of the China National Institute of Standardization and the Institute of Standardization of Resources and Environment, told this reporter that the national standard for solar water heating systems has been released 15 times, but at present, China's solar thermal power generation standard system is still lacking, and the field is currently being developed. The standard, meanwhile, the new Solar Standards Committee will be established in the near future.
For the Chinese PV industry, where 98% of solar cells are used for export, this is obviously not a good thing. Europe and the United States have higher requirements for standards and quality certification of photovoltaic products, which is the main challenge facing China's PV industry.
In addition to the lag in standardization, the state still has room to support the photovoltaic industry's support policies and development plans.
Wang Sicheng said: The Renewable Energy Law has been in force for two years, but it has not yet been implemented on photovoltaic power generation. So far, the power sector has not officially accepted photovoltaic power generation online. Several photovoltaic grid-connected power generation projects in China and other regions in the west are only demonstrations and have not produced benefits.
According to foreign experience, there are two main ways for developed countries to promote the development of photovoltaic industry: one is the Japanese subsidy law, and some subsidies are given during installation. As the market develops, the government gradually reduces subsidies, which is ultimately determined by the market. The other is the German way, which is forced by the state to purchase photovoltaics.
In 2006, the German PV market surpassed Japan. The “On-grid Electricity Price Law†issued earlier was a great success. As the installed capacity of photovoltaic systems doubled and the cost dropped by 20%, the cost of photovoltaic power generation dropped rapidly. From 2004 to 2007, the price of electricity in Germany fell by about 17% in three years.
Professor Cui Rongqiang, executive director of the China Renewable Energy Society and the Solar Energy Research Institute of Shanghai Jiaotong University, suggested that in the initial stage, China can adopt a combination of initial subsidies and electricity price subsidies. This will help promote the development of the photovoltaic market and accumulate the basis for large-scale applications.
Wu Dacheng, executive director of the China Renewable Energy Development Project Office, told this reporter that the current market share of photovoltaic systems in China is: rural electrification accounts for 42%, communications and industrial applications account for 30%, and photovoltaic products account for another 28%.
Wu Dacheng said that solving the problem of electrification in rural areas without electricity is the main goal of the Chinese government in rural energy construction in the next 10 years. Photovoltaic power generation and wind-solar hybrid power generation will be the most important technical means due to sufficient light energy in the underdeveloped areas of the northwest.
