Portable solar container house will go to the United States participating

Tongji University students designed and built mobile solar container housing 16 shown in Shanghai, providing a new way for people of low-carbon life, and will participate in this year held in Washington in September of 2011 American Solar Decathlon competition. Day, cost $ 250,000, six containers assembled into a Y-shaped space, fully equipped with indoor furniture, appliance, all supplied by the solar electricity at home \"container sun room\" to attract the attention of everyone.

Reporters on the scene saw a total of 90 square meters of space, can accommodate one person, \"comfortable\" life of the solar house, to spread bamboo floor, housing on one side with a folding double bed, the bed is put away after the cabinet. The other side is a fully equipped kitchen and bathroom, erection of roof solar panels to provide electricity and hot water, domestic water system by the sewage purification process. The middle of a small living room and study the function of both restaurants. South transparent housing, 120 for each 2-degree angle between the assembled container was designed to provide residents with the maximum angle of view. Link at the container floor through the glass door and around to the external terrace homes. Only houses on both sides of the huge metal insert lock, will remind people of this lovely house with heavy container are linked. \"Ceiling, walls, floors are equipped with new high-performance vacuum insulation panel; the collectors and air-conditioning waste heat recovery, are integrated, to improve the overall efficiency of solar energy\", project leader, green building and Tongji University New Energy Research Center Deputy Director Tan Hong Wei introduced a number of building integrated solar house energy-saving technologies, such as the use of light pipe to the introduction of natural light for indoor lighting, roof equipped with rainwater harvesting and water reuse systems, to maximize the use of natural resources. In addition, indoor environmental monitoring, energy management, facilities management, all to achieve a digital, information, visualization, residential capacity, energy consumption, living environment and other data in real-time visual display, but also the use of 3G mobile phones and other mobile terminals remote control.

Environmental protection and good value for money is the concept of the entire design team. Person in charge of student housing projects Sun, Tongji University architecture students Hua Guodong said Kenji, \"International House on the cost of these environmental standards is usually $ 400,000, we use recycled green materials, only 25 million dollars, much easier for people to accept. \" Quickly and easily removable, long-haul transport, but also the use of existing structures, site conditions, different fight Dachu different combinations of flexible space is a \"container sun house\" is another feature. Tan Hongwei, said that this model can be extended to construction waste container transformation, disaster, and many other temporary shelters housing projects built in.

Solar Decathlon competition sponsored by the U.S. Department of Energy and organized every two years, each in a worldwide selection of 20 universities participating. Each participating university student teams to design, build out a unique solar-energy solar homes and fully equipped with appliances and furniture and other everyday living facilities. \"We hope the next Solar Decathlon competition also in China, held in Shanghai,\" said Li Yongsheng, vice president of Tongji University.

Solar energy to achieve grid parity in

      On June 9 meeting of the development of large-scale solar power seminar, the National Energy Board new and renewable energy, said deputy director Liang Zhipeng, preliminary consideration of the Energy Bureau, China s solar power by 2015 to achieve the user side of parity, to the price of solar power in 2020 with basically the same as traditional fossil energy sources.
      At present, the price of solar power, without considering the case of land costs about 1 yuan per kilowatt-hour, in which the price of PV down to 0.73 yuan, but still 3-4 times the price of coal-fired power generation, and Wind power also higher compared to about 50%. 2015 users online side of parity means to achieve grid parity solar power during the second five the price of 0.2 yuan will be lower and lower, that to the cost of solar power down to 0.8 yuan per kilowatt-hour or less, PV price reduced to 0.5 yuan, with the current wind power prices were flat. "Currently under construction, 100 million kilowatts, the future will be an annual increase rate of 100-200 million kilowatts of installed capacity is expected that by 2015 China s solar power capacity will reach 10 million kilowatts." LIANG Zhi-peng said. However a month ago, the National Energy Board chief engineer Wu Guihui disclosed the Energy Bureau of the "solar energy development plan" or solar power installed capacity in 2015 reached 500 million kilowatts. Just 30 days, solar power, "planning" capacity will achieve the double.
      According to the National Energy Board new and renewable energy Energy Division Director Dong Xiufen introduced above 10 million kilowatts installed capacity consists of three parts. Which in Qinghai, Xinjiang, Gansu and other provinces start solar power base in Inner Mongolia, Ningxia, Shanxi, Tibet, etc. to promote the key large-scale solar power projects, these large-scale solar power plants account for about 6.5 million kilowatts.
      In addition, about 300 million kW distributed photovoltaic projects, mainly concentrated in the eastern region with energy-based, consumption indicators in accordance with arrangements for the project, to encourage self-occupied, the remaining about 50 million kilowatts, mainly off-grid solar systems, as remote areas without electricity, power shortage area applications.
According to the Energy Bureau data released at the meeting, as of the end of 2010, China s cumulative PV capacity of 86 million kilowatts, of which grid-connected PV 70 million kilowatts, 160,000 kilowatts of photovoltaic off-grid; then added 580,000 kilowatts, of which grid-connected photovoltaic 550,000 kilowatts.

Solar energy companies should be re-positioning coordinates

      Looking for a long time the results of the third solar countryside successful, and finally to 243 solar energy companies won the bid, the successful rate of 92% in the end, this result seems somewhat contrary to the expected solar energy companies. Successful result was announced, the industry in an uproar, such a high winning rate, how to make solar energy companies where to go? The solar market next year will be more tragic? Faced with such competition in the market pessimists have the atmosphere, there are the optimists. Xu Jing Pu Solar Power vice president of marketing, said in an interview, so many solar energy companies won the bid, to actually make solar energy companies have returned to a competitive origin, in such an environment, while promoting capacity of the terminal depends on the enterprise, and the other On the one hand is the weight of the brand in the minds of consumers.

The general manager of Tongji sun Jin stressed in an interview, solar energy to rural areas is bound to accelerate the industry reshuffle, the first is from the dealer shuffle began. The combat capability of the terminal distributor business is stronger, the higher survival rate, the weaker the combat capability, the greater the likelihood of being washed off.

The solar industry calls these years has been shuffling high hopes solar energy to rural areas people have been able to gradually compress the number of enterprises, in fact, the two policies to promote solar energy to rural areas open to the future, does play a certain amount of catalyst, the most may be a clear case of solar energy companies around Haining, Jiaxing Solar Energy Industries Association, according to Xu Zhu Ling teacher, this year, one-third of solar energy companies have begun to transition to other relatively high-profit industries. In fact, as this transformation may well be a good policy, in the current solar industry, increasing competition in the case, instead of the red sea in a fight, not as early as possible to other areas of their more well-known transformation. Like the solar industry, business, turnover is high, current flows to many members of other relevant environmental protection industry, which is a favorable evidence. So, if the brand is difficult to further increase to some extent the case, not as early as possible transition. Struggling with, it would be early to catch the fast track of growth in some industries.

So, for the growing solar energy company which, if you give up the painstaking efforts of the brand, is tantamount to give up halfway. Slightly longer to grow up quickly insist there\\ s hope. Two years ago the solar wind industry has come a rain along the years, and now, faced with such third solar energy to rural areas the opportunities and challenges, the only difficulties to get more business development. Today, major companies have to adjust strategy, some companies no longer business as the rapid development of solar energy to rural areas only help stabilize the grass, adhere to the brand diversification. Solar industry in Jiangsu and Zhejiang provinces visited enterprises found that solar energy will be as close Cher made a \"living museum\" that the concept of life, the solar energy, green kitchen, ceiling products focused on sales, which may well be a good sales model . Changzhou billion solar energy as one family to focus on rural sales in the same time, the brand positioning in the \"people to create the most trusted brand of energy\" in the under the guidance of the core product, imported European wall-hung boilers, water purification equipment, etc. a variety of energy-saving products, diversified brand management strategy. Wuxi ring as special outside support solar energy, the less promote, the persist operation of independent brands in foreign markets was a big success. These are the more successful cases. Therefore, regardless of solar energy to rural areas as business, corporate or non-rural areas, in the brutal competition in the market, companies must find their own advantage, in time to adjust their business strategy, I believe that the pattern in the industry will eventually find their exact coordinates .
