Solarbuzz, the world-renowned photovoltaic research institution, reports that the Asia-Pacific region will become an important photovoltaic market in the world, accounting for 25% of global demand by 2015, which is a significant increase from 11% in 2010. This injected a booster for the PV market in the first half of the entire industrial chain. According to the report, the total PV market demand in China, Japan, India, Australia and South Korea in the Asia-Pacific region is expected to reach 3.3 GW by the end of 2011. China, India and Australia have begun to build a grid-connected photovoltaic power generation market. The country benefits from its support for the New Deal and its demand growth is the most advanced.
According to a report by Solarbuzz, a diversified PV technology development in Asia Pacific, the scale of China's PV market in 2011 could expand by up to 174% over the previous year. In 2010, the Ministry of Finance, the Ministry of Science and Technology, the Ministry of Housing and Urban-Rural Development, and the National Energy Administration jointly convened a meeting and announced the list of the first 13 pilot demonstration areas for PV power applications. It also pointed out that China will enter Giva after 2012. Photovoltaic installed power ranks.
Japanâ€™s nuclear power generation accounts for about 30% of total power. After the accident at the Fukushima nuclear power plant, the development of renewable energy such as solar energy has become increasingly strong. However, from the perspective of the development of renewable energy, Japan lags behind the world trend, and its solar and wind power generation accounts for only 1% of the total. How to achieve rapid growth of photovoltaic power generation? Sun Yat-sen, president of Softbank, has a bold idea: Japan has 200,000 hectares of fallow farmland and 340,000 hectares of abandoned land. If solar panels are installed on 20% of the land, its power generation capacity is equal to the total power generation of Tokyo Electric Power Company. This will not only rapidly popularize renewable energy, but also use abandoned land.
India has a unique advantage in photovoltaic power generation. It has enough sunshine for about 250 days to 300 days every year. As long as the solar energy received on its 1% national land area is fully utilized, the country's electricity demand can be met. The Indian government launched the Nehru National Solar Energy Program in 2009 and will invest 70 billion U.S. dollars to increase the grid-connected generation capacity of solar energy to 20 GW in 2022, equivalent to 1/8 of India's current total electricity generation. According to the forecast of the international accounting firm KPMG India, the solar energy development in India will show a trend of blowout, and the solar power capacity in 2022 will reach 68GW, which is more than three times the official target.
South Korea implements a "renewable energy quota system," in conjunction with the existing mandatory on-grid tariff policy, and adopts regulations to regulate the proportion of various renewable energy sources in the country's energy supply, including the proportion of solar energy.
Zhou Aiming, an energy expert from the Asian Development Bank's Regional and Sustainable Development Bureau, told the reporter that PV technology in the Asia-Pacific region has shown a diversified development trend, as well as its own innovative R&D and patents. For example, China Suntech Solar Power Co., Ltd. has established a world-class R&D center dedicated to thin-film photovoltaic cells, a cutting-edge technology that helps reduce the cost of photovoltaic power in the future. However, the most advanced photovoltaic technology is still in Europe and the United States.
At present, the production capacity of photovoltaic cells in the Asia-Pacific region is very strong, accounting for about 2/3 of the world's total production capacity. Among them, China and Japan are the two countries with the highest output of photovoltaic cells, and output is basically equal.
Price is the biggest bottleneck for photovoltaic development Dr. Ren Fujian from the Department of Materials of China's Tsinghua University said in an interview with reporters that at present, the price of photovoltaic power generation in China is about RMB 3/kWh. Although China's photovoltaic industry level is close to the world's advanced level, China's main single-crystal silicon The production costs of polycrystalline silicon materials are still high. For example, for a 3-inch single crystal silicon wafer, the import price is more than 60 yuan. The domestic production price of the same product is more than 100 yuan.
At present, India's photovoltaic power generation capacity is only 0.04 GW. The main difficulty is the shortage of funds. The cost of solar power is about 12 to 14 rupees per kWh in India (1 US dollar is equivalent to 44 rupees), which is much higher than the cost of coal-fired electricity at 5 rupees per kilowatt-hour.
It can be said that the biggest bottleneck of photovoltaic power generation is the price issue. Excessive prices have affected the further expansion of the market. The impact of technological innovation on prices is still less than the impact of lower cost of polycrystalline silicon. At present, the main problem facing the development of photovoltaic technology in the Asia-Pacific region is that the ratio of the cost of solar photovoltaic system generation to the average price of the grid is relatively high and it needs the support of government policies. China, India, Japan and South Korea have adopted active support policies to support the development of solar energy projects.
In general, the photovoltaic industry chain in the Asia Pacific region is relatively complete. In the next few years, grid-connected solar systems should be the mainstream, followed by rooftop solar systems, and finally, off-grid systems in remote areas.
Development of solar energy must not be done overnight Professor Lin Boqiang of the China Energy Economics Research Center at Xiamen University told this reporter that there are many reasons for the rapid development of the photovoltaic industry in Asia Pacific countries. First of all, the main share of photovoltaic market demand is in Europe and the United States market. China's polycrystalline silicon has long been exported to the European market in large quantities. The size of the photovoltaic power generation market in the Asia-Pacific region is still relatively small, but there is a lot of room for growth in the future. The photovoltaic industry requires a large amount of funds, and the development situation is in line with the economic cycle. Now that the EU economy is under the influence of the sovereign debt crisis, it will be uncertain, and its photovoltaic market will develop slowly in the coming period of time. This has brought opportunities for the development of the Asia Pacific PV market. Secondly, the Japanese nuclear power plant accident has made new energy technologies attract attention, and wind power and solar energy have become new energy sources. In recent years, the development of wind power has been affected by technology and market, and it has entered a period of rectification from the early period of rapid growth. Solar power has thus become a potential market in the future. The Chinese governmentâ€™s support for the photovoltaic market is also relatively large.
Zhou Aiming also pointed out that photovoltaic solar power generation technology is a kind of new technology, and its resource supply has intermittent characteristics. Therefore, for solar energy in the entire energy supply structure, countries should have a more comprehensive and objective understanding. Solar energy is a kind of renewable energy. Many countries in Asia are vast and contain abundant solar energy resources. The development of solar energy resources is the trend of the times. Asian governments should strongly support them, but they must not blindly invest and unrealistically expand the scale.
