The Sino-European PV trade dispute has come to a close, and the two sides have adopted a "not satisfied" agreement. The "external troubles" of China's photovoltaics have been suspended, but "internal worry" continues. After the bankruptcy of Wuxi Suntech, which was once flourishing, the market was still clouded. Suntech’s tens of billions of debts made Tianhe Solar and Yingli Group and other major PV companies deterred. Suntech is not the only one in this round of “photovoltaic shufflingâ€. On August 7, the Jiangsu Photovoltaic Professional Committee reported that six PV companies in the world filed for bankruptcy in July, including two Chinese companies. A subsidiary of Henderson Photovoltaic and Variety. It can be said that in this big reshuffle, few PV companies are able to stand alone. Since the outbreak of the crisis in China's photovoltaic industry, multi-party analysis is fundamentally lacking the combination of “production, learning and research†in the photovoltaic industry and it is urgent to strengthen innovation at both ends of technology and application. Recently, the State Council issued the "Several Opinions on Promoting the Healthy Development of the Photovoltaic Industry", proposing that the average annual installed capacity of photovoltaic power generation will be about 10 million kilowatts from 2013 to 2015, and the total installed capacity will reach 35 million kilowatts or more by 2015. The "Opinions" also pointed out that while expanding the application of photovoltaic power generation, it controls the total production capacity of photovoltaic manufacturing, accelerates the elimination of backward production capacity, and strives to promote industrial restructuring and technological progress.
Undoubtedly, the photovoltaic industry has entered the integration period. At this time, there is Hanergy in the “shoppingâ€. In July, Hanergy successfully acquired the US company GlobalSolarEnergy. The acquisition of GSE has made Hanergy the first company in the world to achieve mass production of flexible thin-film solar modules, occupying the forefront of thin-film photovoltaic technology. At the same time, the central enterprises represented by the five major power sources and China Guangdong Nuclear Power, Three Gorges Group, SINOMACH, and China National Aviation Corporation are now rapidly grabbing the photovoltaic power station market while the photovoltaic private enterprises are struggling.
In August of this year, the solar decathlon competition was held in Datong, Shanxi. For the first time, it was co-sponsored by the National Energy Administration of China and the US Department of Energy. The Ministry of Finance, the Ministry of Housing and Urban-Rural Development jointly sponsored it, and the Central Committee supported it. The China International Solar Decathlon (SD) hosted by Peking University will bring students from all over the world to zero. The understanding of energy-consuming buildings integrates the economical and intelligent way of life and entertainment into green buildings, bringing a fresh look to the development of solar energy. It can be said that the establishment of this competition in China is undoubtedly the embodiment of China's emphasis on the promotion of new energy applications and the fulfillment of the responsibility for energy conservation and emission reduction.
Transformation and development of solar energy
Zhang Yuqing, deputy director of the National Energy Administration, fully expressed his great confidence in the development of solar energy in China during the SD competition. He believes that the total installed capacity of solar photovoltaic power generation in the world reached 101 million kilowatts in 2012, and the commercial application of solar power technology is steadily launched, which indicates that the era of large-scale use of solar energy has arrived. He mentioned that the Chinese government proposes to make full use of solar energy in the process of urbanization development, combine building energy conservation, strengthen photovoltaic power generation applications, and promote the integration of photovoltaic building. This is the purpose and concept of solar competition, and also the solar competition in China. An important foundation for landing and rooting.
As the host city of SD, Li Junming, the mayor of Datong City, said that Datong will adjust its industrial structure, insist on using coal as the machine, and use coal to produce, and develop with coal industry. In the development of new energy sources, Datong took the opportunity of this SD competition to create a national new energy demonstration city, strengthen energy conservation in the three major fields of industry, construction and transportation, highlight the leading position of the new energy industry, and build wind energy, solar energy, etc. New energy industry base. The transformation plan of Datong has played a leading role in transforming the development mode for many “new energy demonstration cities†and the extensive cities that actively respond to the model call.
Today, with the development of new energy sources in full swing, foreign countries have accumulated a lot of experience worthy of our reference in the development of new energy.
In Denmark, where the energy self-sufficiency rate is 156%, Zhou Fengqi, vice president of the China Energy Society, president of the China Renewable Energy Industry Association, and former director of the Energy Development Institute of the National Development and Reform Commission, believes that the success of the support of the Nordic power grid will give China a success. The revelation is that the transformation of the entire energy system is very important. He proposed that the power system in China was mainly based on coal-fired units, and the thermal power system was mainly operated. The peaking was carried out with other auxiliary energy sources, and there was little natural gas. However, if renewable energy is the main force, the original coal-fired unit should be used as a peaking. This power system must be reformed and the electricity price must be reformed.
Ouyang Lan, Secretary of the Environmental Science and Technology Health Department of the US Embassy in China, gave some summary of the development experience of the United States in the field of photovoltaics. She said that at the beginning, the US research on photovoltaics was very positive, and the new industry had high risks after all. Therefore, the US government supports the US Department of Energy's Lawrence Berkeley National Laboratory for related early research. The second step is to expand the market. Let the city's development replace fossil energy with new energy as much as possible. At the same time, the state encourages the use of new energy, form a standard investment portfolio of industrial reputation and new energy, and then promote the use of solar energy to popularize the solar panel rental method. .
Solar energy companies are gradually recovering
The students who participated in the SD contest were very curious about the operation status of PV companies during the conference. Many of them are planning careers for entering the solar field in the future. The PV giants who have gone through two years of “photovoltaic shuffling†have summarized the various problems faced by China's PV companies and how they can “live†in this war.
Gao Jifan, chairman and CEO of Trina Solar, believes that reducing power generation costs in the future is the core of PV development, and the path is through industry innovation. "In the past two years, the gloom of photovoltaics is because they can't innovate." He said that he went abroad to participate in the exhibition and saw all the buyers and sellers in China. This is a very repeated cost investment, which is a waste of money. A really useful solution is to push China to promote industrial renewal as soon as possible. The expansion of enterprises must increase the market scale through innovation. He also suggested that local governments should have the same motivation and passion as investment promotion to promote the merger and introduction of photovoltaic enterprises.
Founded only 6 years ago, Shu Hua, the CEO of GCL-Poly, the world's top three in the polysilicon industry, pointed out that the problems in the industry are first of all a shortage of funds. Then many PV companies lack corporate responsibility. He stressed that the development of new energy industry must be certain. To be green and to recommend that to regulate the industry requires constraints on product quality and overall operations.
Xu Xinjian, chairman of Sunrise East, an expert in the field of solar thermal energy, put forward the concept of “big light heatâ€. His idea is to expand the industrial margin of solar energy and open up the market for industrial heat. He believes that solar thermal power generation will be a new force in the new energy industry. At the same time, he said that solar thermal energy companies should focus on channels and have greater demand for agents. For photovoltaics, its potential is not only a power station, but the future potential market should be an independent household power grid.
In the past two years, Wu Tingdong, deputy general manager of JA Solar, said that the current problem facing the photovoltaic industry is the rise of global trade protection. In addition, local protectionism is emerging in the country. In different regions, the governments of different provinces benefit from their respective interests. From the perspective of making appropriate policies or actions, or for local interests, or for the industry, from the perspective of the entire industry or industry, it may not be a good decision. Taking Jingao as an example, they have achieved certain results through their own efforts, technological innovation and new market expansion in the past two years. Wu Tingdong believes that in the downturn of the industry, enterprises can only make continuous efforts. Technology improvements, independent innovations, including the expansion of emerging markets, can survive, and he said that "the industry will live better in the future."
Solar building with small size
On August 11, the closing ceremony and awarding ceremony of the 2013 China International Solar Decathlon Competition, which was hailed as the “Solar Building Olympicsâ€, was held in Datong. The University of Wollongong, Australia, the South China University of Technology team and the Swedish Chalmers University of Technology team were awarded the third place in the SD event. As can be seen from their architectural works, each team has fully utilized their creativity and wisdom in this event, not only in the shape of the house, the layout of the interior space has a good idea, but also in the solar photovoltaic light The thermal system, the water system and the smart home have all been designed in a very human way, which combines energy-saving technology with an environmentally friendly lifestyle. In the past month, these 20 energy-efficient and livable passive energy houses have stood alone in Datong, forming a green landscape and attracting visitors from all over the world.
Richard Sikkim, director of the International Solar Decathlon Competition, as the founder and head of the US Department of Energy's solar decathlon competition, said that the original intention of SD is to build components more reliably, while educating the market. What is the potential of the market and what makes consumers more willing to buy. He mentioned that after the end of SD China, California will also hold its new round of the US version of the solar decathlon.
Yu Pingrong, Chairman of SD China's Competition Organizing Committee, commented on the event: In the past three years, 13 countries, 22 teams, 35 schools, more than 200,000 visitors, and hundreds of millions of people have known SD through the media. The event achieved a much higher than expected success. He said that in terms of innovative technology, at least tens of millions of people know that the combination of new energy and energy conservation can make a house self-sufficient in energy. Through such an international event, the public is also aware that the combination of these technologies can be so elegant. And art.
Li Junfeng, chairman of the Renewable Energy Professional Committee of the China Resources Comprehensive Utilization Association, which has visited 20 solar houses with different shapes and specific objectives, said that the solar decathlon has promoted the transformation and development of Datong. At the same time, he also stressed that he saw many Chinese designs and foreign designs at the event, and believed that we should learn more in the details.
At the same time, it is worth noting that for the first time, the competition merged the microgrid built inside the solar house into the national grid, and the two sides realized reliable connection and two-way power supply. (The microgrid is a kind of grid structure formed by the combination of distributed power supply and users. When the distributed power generation load matches the user's power load, the microgrid can operate independently of the external grid.) In fact, the distribution The key to power generation is the rational allocation of energy.
The solar decathlon competition tested the students' "decathlon". In their two years of preparation for the competition, it was also a key year for China's photovoltaic industry. Today, the country's promotion of clean energy is further advanced, and the use of new energy sources has become more and more indiscriminate; the smart and energy-saving methods emerging from the SD competition are infiltrating into people's energy-saving life concept; the photovoltaic light-heat industry is also like people from all walks of life. As you can see, it is entering the second start-up period. Driven by the “all-round†storm of “production, learning and researchâ€, such as the solar decathlon, China’s solar energy industry is entering a more hot and vibrant future.
Solar decathlon competition introduction:
The Solar Decathlon Competition (SD) is an experimental competition for college students worldwide, sponsored and hosted by the US Department of Energy. The aim of the competition is to combine the creativity of the world's top R&D and design teams to integrate solar energy, energy conservation and architectural design in a new way to prove that even a solar-powered home can be functional, comfortable and sustainable. Sexual living space, thus promoting technological development and practical progress in energy conservation and emission reduction.
The solar decathlon competition was held only in the United States and Europe, and SD China was the first time in Asia to attract the participation of 22 teams from 35 countries and 35 universities (finally 20 teams were built). Housing), which includes both an independent university team and a multinational university team, fully reflects the international and communication nature of the event, and includes outstanding talents in design, power, environmental protection, construction, materials and other fields. In the real house construction process, many cutting-edge, advanced and experimental programs have been realized, and the built houses are also open to the public. It is a very popular solar energy event.
