Zai tight global energy situation, global warming a serious threat to economic development and people and healthy living in today, the world's nations are looking for new energy Tidaizhanlue, in order to Qiude sustainable development and in future developments Huoqu advantage Di Wei. Solar energy for its clean, steady flow, security and other significant advantages, the focus of attention. In the solar energy industry in the development of solar thermal water heater conversion technology is undoubtedly the most mature, and its industrialization process than photovoltaic cells, solar power and other industries one step ahead. But the market has yet to be standardized, consumers have yet to be nurturing, technology also needs to improve, so for larger enterprises, there is room for growth.
China has extremely rich solar energy resources, solar radiation in total more than 5,000 trillion joules per square meter, the annual sunshine hours over 2200 hours over the area land area about 2 / 3. This is the solar energy industry in the best interests of the external objective conditions.
Solar water heater solar energy resources in China, five areas of energy per square meter of collector area festivals were 170,140,120,100 and 80kgce/m2, while in energy-saving, solar water heater also has obvious environmental benefits, five areas reductions of carbon dioxide per square meter respectively, 306,252,216,180 and 144kg/m2, protection of the environment played a role.
China's large production capacity of solar water heaters, with their number, rapid development has attracted world Guan Zhu, the State Economic and Trade Commission, United Nations Foundation, "China's solar water heater industry," International Cooperation in 2002 officially started.
In 2003 production reached 12 million square meters, flat-plate collector in 2003, 18 production lines (copper and aluminum composite and copper), capacity 2.7 million square meters.
Solar heater in 2004 about the amount of renewable energy development and utilization of 30%, second only to the contribution of small hydropower, solar water heater to the end of 2004, production in China has broken through 10 million square meters, ownership in more than 60 million square meters. Estimated using the vacuum tube in 5.6 million of its sales in the next stage. Industry output value has more 120 million value of about ten billions of dollars, of which Wong Ming, Qinghua Sun, Hua Yang and other integrated production is relatively high, also see the sun the rain, four seasons Mu Song, Sang Le, Marino, etc. 2004 years of good performance, its value has been more than 100 million. The Journal of Young in a three, the output value, volume has improved greatly.
The development of its product categories, is this glass vacuum tube basically occupy more than 90% of domestic sales, while the proportion of flat plate solar water heater for less than 10%. Compared to sales for 2003, an increase of about 18% or so. 2004, manufacturers have more 4000 and less than 17% of the top ten brand market share highlights the very low concentration of the industry's immaturity.
Regional sales from the form view, the market remains the main north brand competing in strategic locations, but almost simultaneously started from end-2003, major brands have to look for ways to develop most rapidly in Guangdong, Fujian and other southern markets. The whole, Jiangsu, Yunnan, Shandong region remains the highest penetration rate, Zhejiang, Anhui, Beijing and Tianjin followed.
The full year 2005, the country is expected to reach annual production capacity of solar water heater 11 million square meters, the total volume of 64 million square meters tenure; the formation of internationally competitive 5-10 furniture backbone enterprises. China plans by 2020, solar water heater collector area, from the current 64 million square meters to 300 million square meters development, alternative fossil fuels in about 4,000 tons of standard coal.
As can be seen from the figures above, whether from the point of view, solar energy and solar water heater industry is huge room for growth to look forward to a sunrise industry!
