More than half of global solar water heaters are produced in China
The reporter recently observed in Aijia Village, Licheng District, Jinan City, Shandong Province that solar water heaters are installed on the roofs of every farmer and the street lights in the village are also solar. It is understood that the use of solar water heaters in China and annual production has accounted for more than half of the world total.
As of 2006, China's solar water heaters have an installed capacity of 90 million square meters, accounting for 76% of the world's total area of solar water heaters; annual production capacity exceeds 20 million square meters; annual output value of solar water heaters is more than 30 billion yuan, and foreign exchange earns 50 million US dollars.
According to Huang Ming, chairman of Huang Ming Solar Energy Co., Ltd., China's own solar water heater technology accounted for more than 95% of the city's solar water heater penetration rate reached 25%. In the construction of a solar energy utilization standard system,
At the end of 2006, 20 standards were promulgated and implemented, including 16 national standards and 4 industry standards. At present, China's solar energy industry has formed a supporting industrial chain for glass raw material processing, processing of all-glass heat collection tubes and water heaters, marketing services, machinery processing equipment and spare parts production.
However, compared with developed countries, China's per capita solar water heaters use area is still relatively low. At present, the per capita use area of solar water heaters in developed countries is about 0.5 square meters, while the average per capita in China is only 0.03 square meters.
Shen Wenming, vice president of Shandong Linuo Group, said: "One of the heavens is a common human wealth. The use of solar energy should be a major breakthrough in the government's efforts to promote energy-saving and emission reduction. Everyone should feel proud to use solar energy." An energy-saving account: If China's 350 million households use solar water heaters and each house supplies 100 liters of hot water per day, it can save about 400 billion yuan in electricity bills each year, which is equivalent to 3.7 Three Gorges power stations. Reduce large amounts of carbon dioxide emissions.
At present, the Chinese government is organizing the preparation of a standard specification for the integration of solar water heaters and buildings, and has carried out a series of pilot projects integrating solar water heaters and buildings in different climate zones such as Beijing, Tianjin, Shandong, Shanghai, Yunnan and Guangxi. project. Since this year, cities such as Yantai and Jinan have successively promoted the integration of solar energy and building design and construction in the form of government documents. People in the industry believe that with the advancement of this measure, solar energy heat utilization technology will make a huge contribution to China's building energy conservation.
