Solar photovoltaic industry: the prospects are bright and domestic


Jin Zhengxin pointed out that renewable energy is expected to account for more than 30% of the total energy structure by 2030, and the proportion of solar photovoltaic power generation in the world's total Power Supply will reach more than 10%.

Zhou Lang, a member of the National Committee of the Chinese People's Political Consultative Conference, acknowledged the embarrassment of the domestic market, but confidence. His roots in the confidence of the photovoltaic industry are driven by the will of the country, stemming from the global climate deterioration and the demand for clean energy in the context of the energy crisis. This direction will not change. Moreover, he analyzed that the current financial crisis is an opportunity for the solar photovoltaic industry.

In mid-March, Zhou Lang, member of the National Committee of the Chinese People's Political Consultative Conference and dean of the School of Materials of Nanchang University, returned from Beijing to attend the meeting and met with a delegation of Taiwanese businessmen who came to Nanchang for inspection. More than 20 people from the Taiwanese industry in the photovoltaic industry have a high interest and have carefully investigated various conditions in Nanchang. Nanchang has been recruiting to build the world's largest photovoltaic industry base. On the other hand, Gong Jianming, member of the National Committee of the Chinese People's Political Consultative Conference and vice chairman of the Hunan Provincial Political Consultative Conference, also pointed out at the two sessions that it is recommended to include Hunan in the national photovoltaic industry base to support it.

True or false

Some people may not understand the plans to vigorously develop the photovoltaic industry everywhere. Is that the two ends (raw materials and markets) leaving pollution and energy consumption to their own industries?

Zhou Lang is very opposed to this statement. During the two sessions, he made a special statement on whether the current solar photovoltaic power generation is worth the loss, whether it is high energy consumption, whether it is highly polluted, and whether it sacrifices China's resources and environment for Western service.

In 2007, China's solar cell production has become the world's king, and the solar cell production in mainland China has reached the second place in the world. An industry can develop so rapidly and be at the forefront of the world, which is very rare in China. The good news is that this is still a promising new energy field. Zhou Lang told reporters of Energy magazine.

However, with the continuous increase in domestic investment in the photovoltaic industry in recent years, the domestic and international circles have raised many doubts and even blame on photovoltaic power generation and its supporting industries. In Zhou Lang, most of these problems can be answered at the technical level. All that is needed is Scientifically and objectively think about reasoning, collect factual data, and add a little computational analysis.

He used the habits of scholars to give three sets of figures in terms of energy yield and energy consumption: the current working life of crystalline silicon photovoltaic cells is more than 25 years (after 25 years, the power generation capacity drops to 80% of new batteries), and manufacturing The electricity consumed by this battery can be recovered after two to four years of power generation. The energy income is about 10 times, and this income ratio can be increased with the expansion of the market and industry scale;

The research and calculation of the electricity consumption level for each production value of RMB 100 in steel, aluminum and solar high-purity silicon chemical production, the highest level of electricity consumption in aluminum smelting, reaching 113 kWh, while the production of high-purity silicon is the lowest. 10 kWh;

In 2008, the installed capacity of China's photovoltaic power generation system was 40,000 kilowatts. Assuming that its installed capacity is expanded by 250 times, the overall energy consumption is in accordance with the current technical level of the photovoltaic industry. The construction of a 10 million kilowatt photovoltaic power generation system requires 26.5 billion kWh of electricity, accounting for the total national total in 2007. The power generation is 0.8%, while aluminum smelting accounts for 5% and steel for 14%.

Therefore, the photovoltaic industry cannot be called a high energy-consuming industry. He said.

Regarding whether the photovoltaic industry is highly polluted, he explained that the pollution problem is mainly in the production of upstream high-purity silicon raw materials. There is no technical difficulty in the waste water and waste gas produced from recycling or pollution-free treatment. The country has also broken through foreign technology blockades and realized this technology. Moreover, he feels that this problem can be solved with simple reverse thinking: high-purity silicon production supply has long been controlled by the seven companies in the United States, Germany, and Japan, and has not been transferred to other countries. The environmental control and regulations of these three countries are very strict. If high-purity silicon production is a highly polluting industry that cannot be controlled, can it exist in these countries for a long time?

He talked about such public opinion. Some people in the West accused China's PV industry of occupying its city and indirectly enjoying its government subsidies. However, China has accused it of sacrificing China's resources and environment for the West.
