Recently, the reporter learned from Dongguan, a well-known solar manufacturers, despite the pressure of rising raw material prices, solar water heater prices generally rise after the Spring Festival, the first quarter of this year, the plant solar water heater sales still substantial growth over the same period last year, whilethe national "energy conservation" policy to promote and solar building integrated climate impact of the plant on the promotion and application of solar hot water project also achieved quite good results, including new residential system installed to become a major bright spot , 2008 solar companies competing priorities. 

   Authoritative statistics show that China's annual new construction of about 20 million square meters, the building energy consumption reaches 20% of the total energy consumption, building energy efficiency is the key areas of national energy saving target. In accordance with the requirements of the Ministry of Construction, to 2010, China's new buildings achieve green building and energy efficient building standards in the fight for more than 30%. Professionals believe that building energy efficiency can be achieved through a variety of ways, depending on building materials and energy saving can not meet this standard, the application of wind controller energy, or the best choice. 

   Looking at the domestic policy environment, and promote new residential energy-efficient, unified installation of solar hot water systems is the trend. "Of solar thermal Commission of Guangdong Province, Guangdong Fivestar pure sine wave inverter Energy Co. Chairman Hu Guang-liang, analysts say. He gave reporters cited a few examples, Beijing this year will be 5.3 million square meters of affordable housing, limited to two rooms, low-rent housing unified installation of solar hot water systems; Jiangsu Province, from January 1 this year, the new 12-story The following dwelling must be unified installation of solar hot water systems; 

Deployment this year, Hebei Province, the province's solar and other renewable energy annual utilization rate of more than 30% of the new buildings completed in total; Wuhan City, with effect from April 1 this year, the 12-storey new building must be installed solar water heating systems, and to encourage more than 12-story residential buildings using solar energy, new buildings are expected annual saving of 137 million degrees. 

   The data show that China's solar water heater applications from a single type to integrated development to the project type, by family type. Industry pointed out that as solar technology advances, more and more families were using solar water heaters, but because there is no uniform design and installation standards, a lot of solar energy equipment installed there are hidden dangers, and through the integration of design and installation of solar hot water systems, to achieve the perfect unity of function and appearance, the effect is more obvious, especially in multi-user buildings such as the collection of residential.
