Recently, this reporter saw a cloud community in dabanqiao street, tree-lined side of the road to put up a root white light poles, solar street lights lined up to the remote mountain village added to many urban atmosphere.

This implementation is Guandu District KEXIN Bureau and a tangible things, good things engineering, solar panel street lights installed in the the cloud community street dabanqiao village roads, completely solve the problem of the residents to travel at night, but also the end of The community does not have the history of the street lamps.

A cloud communities located in remote mountainous areas of the Guandu District, 1272 residents living in this land, but because of economic backwardness, the whole community has no street lights at night, the entire community into a dark, not only to bring residents travel inconvenience and potential safety hazard, residents behind closed doors, will not be able to carry out a lot of community activities.

Decided last month, Guandu District KEXIN Bureau thoroughly implement the implementation of the four groups, education requirements, in-depth rural mountainous area within, to carry out aid work, learned dabanqiao street a cloud of community residents at night dark way truth promote the "green light engineering, the implementation of the" Technology Helping. Actively coordinating relevant departments of the City Kexin Bureau and other multi-raising 50 million yuan of funds, after a Solar Energy Technology Co., Ltd. in Yunnan workers lasted nearly a month of intense construction, the successful completion of 50 solar cell street light base digging, installation and commissioning job.

Guandu District Branch letter by the Secretary Wang Yongquan introduced, this solar lights can make full use of solar energy, pressure effectively ease the power shortage, the night lighting with energy all depend on the absorption of solar energy during the day as the stored energy, the energy of the collection of the day, for eight nights use, the battery in just seven years to replace once will greatly save electricity for lighting, at the same time provide convenient conditions for the villagers to travel at night.

Wang Yongquan The District Branch letter will fully implement the green light engineering, for 3 years, solar street lights illuminate the life of mountain dwellers in the area, and make a positive contribution to speed up the development of urban and rural. As mentioned above, in 10 years, the production of photovoltaic industry in China has exceeded the world's installed capacity is nearly doubled, but the core technology is still stretched.

Polysilicon enterprises, for example, according to the research data, the cost per ton of large polysilicon enterprises up to 35-50 U.S. dollars, some small and medium enterprises and even the per ton cost of more than $ 60. In contrast, the United States, the cost of production of large enterprises in Germany almost are in the 15 to $ 20 per ton.

Costs are so high, profits how to? "Energy saving others, pollution own" this is not a criticism of Chinese PV companies out of nothing. Currently, the vast majority of Chinese photovoltaic enterprises manufacturing operations are concentrated in low technology content, the production process is simple, labor-intensive, serious pollution and power consumption, silicon production, solar charge controller production and module assembly and other low-value-added sectors.

Taken polysilicon purification aspects of Chinese enterprises is still "closed-loop non-modified Siemens process", while Germany, the United States, Japan and other companies have begun to use technology more, less polluting "closed loop modified Siemens process. However, the disadvantage of three (equipment, raw materials, markets) out ", many businesses prefer the funds be used to expand production capacity to get high profits in the short term, but do not want to be used to update the equipment or research and development of new production technologies, which Get the long-term interests of various stakeholders.

Chinese PV production of advanced technology and equipment, and its own state-of-the-art technology patents, what to be frightened in Europe and the United States "double reverse"? This is the lament of many PV experts. But in fact, in the "front money" and "money" game, in front of "money" at least "win" for 10 years.
