Large-scale development of solar photovoltaic power generation

According to the “12th Five-Year Plan” new energy special plan currently being formulated, China’s cumulative solar power capacity will reach 10 million kilowatts in 2015. After the solar power price drops to 0.8 yuan/kWh, it will enter the stage of large-scale development. At the seminar on the large-scale development of solar power held on June 9, Liang Zhipeng, deputy director of the New Energy and Renewable Energy Division of the National Energy Administration, introduced that the large-scale development of solar power depends on technological progress and cost reduction.

Photovoltaic Relay Wind Power Compared to China’s wind power development speed that has been doubled for five consecutive years, solar power generation has always been “tepid” in China.

Although China's solar cell output has reached 8 million kilowatts, which has accounted for about 60% of the world's total, 95% of them are exported to European-based overseas markets, and the domestic solar power market is still small. As of the end of 2010, China's photovoltaic power generation capacity accounted for only 0.08% of the country's 960 million kilowatts of power generation capacity.

In 2009, China started the construction of the domestic solar power market and accelerated market development through concession bidding and the “Golden Sun” project, but the domestic solar power market is still in its infancy.

According to the latest data released by the Energy Bureau, by the end of 2010, the cumulative capacity of global solar power generation has exceeded 40 million kilowatts, and in 2010 it has increased by more than 15 million kilowatts. In 2010, China organized 13 photovoltaic power plant concession projects, and the total scale of solar power projects under construction has reached about 1 million kilowatts.

The “Twelfth Five-Year Plan” released earlier confirmed that China will form 5 million kilowatts of grid-connected solar power capacity by 2015.

According to Dong Xiufen, Director of the Renewable Energy Division of the National Energy Administration, the “12th Five-Year Plan for Photovoltaic Power Generation” formulated by the National Energy Administration has explicitly increased the “12th Five-Year Plan” target to 10 million kilowatts by 2020. The PV installation target may be significantly increased to 50 GW. Compared with the previously announced "2015 China's PV installations will reach 5 GW or more," the goal is doubled.

This move was interpreted by the industry as a timely increase in installed capacity and is expected to prompt the large-scale launch of the domestic PV market.

According to reports, this 10 million kilowatts will consist of roughly three parts: First, during the “Twelfth Five-Year Plan” period, solar power generation bases will be launched in Qinghai, Xinjiang, and Gansu provinces, and major large-scale power generation will be promoted in Inner Mongolia, Ningxia, Shanxi, and Tibet. The project, this section accounts for about 6.5 million kilowatts; second, about 3 million kilowatts of distributed photovoltaic projects, mainly in the central and eastern energy-intensive regions, according to electricity consumption indicators to arrange the project; third, about 500,000 kilowatts Off-grid solar power systems are mainly used in remote power shortage areas.

"The figure of 10 million kilowatts is still just a forecast." Liang Zhipeng also pointed out that "it is expected that the development of the photovoltaic industry by the end of the "Twelfth Five-Year Plan" will be more likely to exceed the planning goals."

Break through the cost bottleneck "Now, the cost of China's photovoltaic power generation has been reduced by half from three years ago. If solar power can reach within 8 cents per kilowatt-hour, solar power can achieve large-scale development, just like current wind power." Liang Zhipeng Say.

Liang Zhipeng said that in the future, the development of China's solar power industry is very clear-cut. It is necessary to accelerate technological progress, gradually expand the scale of the industry, and promote the economic competitiveness of solar power generation.

Liang Zhipeng estimates that by 2015, grid-connected photovoltaic power generation will have a capacity of 5 million kilowatts. Together with the decentralized photovoltaic power generation project, the cumulative capacity of photovoltaic power generation will reach 10 million kilowatts. At the same time, the cost of photovoltaic power generation can be reduced to less than 0.8 yuan per kilowatt-hour.

At present, without considering the cost of land, the cost of solar power in China has already fallen to 1 yuan/kWh, and the target of large-scale production cost of 8 cents per kilowatt-hour is also the distance from the “last mile”.

Liang Zhipeng believes that the main difficulty in solar power now lies in its economy. “At present, the cost of solar power generation is relatively high, resulting in high prices. If a large-scale solar energy application is to be undertaken now, it is still not economically worthwhile.” said Liang Zhipeng.

In response to the price bottleneck, the Chinese government has adopted two policies and measures to support solar power applications: First, support for the construction of large-scale grid-connected solar power stations, adopting the method of electricity price subsidies; second, giving about 50% of the initial investment in the project for financial capital subsidies. To support distributed applications such as rooftop photovoltaics.

Ashok Bhargava, director of the Asian Bank’s Energy Division, suggested that large-scale investment will also drive down the cost of solar power generation. He pointed out: "Solar power generation projects have a very high initial cost, and the cost of solar power will determine the decline in the cost of solar power. In the next three years, we hope to spend $2.25 billion to drive a total investment of $9 billion to promote Asia. The goal of 3,000 megawatts of solar energy scale application. The goal is to reduce the cost of solar power generation. Hopefully by 2020, it will reach 5 euro cents per kilowatt-hour."

Concerned about the Asian market relative to wind power, Liang Zhipeng believes that the advantages of solar photovoltaic power generation is flexibility, and is not affected by the terrain.

"For solar energy, we don't quite like to concentrate on a large area of ​​development in one area. We advocate multiple points of access to the grid, so that it can be absorbed in the distribution network." Liang Zhipeng said.

Liang Zhipeng also said that Chinese solar companies should pay more attention to the Asian market. He disclosed that many Asian countries including India and Thailand have formulated active plans to promote solar energy and will greatly expand the solar energy application market in Asia.

China is the world's largest solar cell producer and its annual output exceeds 50% of global production. However, China's solar energy products are highly dependent on overseas markets. 95% of annual production is exported. Most of them are exported to Europe. Changes in European photovoltaic policies have a greater impact on domestic photovoltaic companies.

Liang Zhipeng reminded that Chinese solar companies cannot always focus on the United States and Europe. They should pay more attention to the Asian market and strengthen technologies such as building integration and smart grid integration. In May last year, ADB announced that it initiated activities to support solar energy development and utilization. By 2012, it will support 3 million kilowatts of solar power applications in Asia, including large-scale solar power plants, rooftop photovoltaic systems, and independent photovoltaic systems in remote areas.

ADB’s support plans also include: China’s four 50 MW thermal power demonstration projects, India’s 500 MW solar power station grid access project, Bangladesh’s 5 MW grid-connected solar photovoltaic power project, and two off-grid wind and solar power projects. The project, as well as technical assistance to support photovoltaic power and thermal power generation projects for the concessions in five provinces in China.

Liang Zhipeng also called for the coordination of regional policies for quality inspections in Asian countries. He said that even if there are even better policies in a country, the market provided is still limited. If countries can all adopt policies with roughly the same direction and appropriate scale, a considerable amount of solar energy market can be formed.
