Recently, Tianjin issued the "Tianjin residential building energy efficiency design standard", which requires that residential buildings with less than 12 floors must be equipped with solar water heaters from July 1. It is understood that Tianjin is not the first city to formulate similar policies. Beijing has implemented relevant policies since January 1 this year, requiring that solar hot water systems must be installed in residential buildings. Since March 1, all newly-built, reconstructed and expanded civil buildings in Xi'an must adopt solar hot water system, which shall be uniformly planned, designed, constructed and accepted with the building. Both the increasingly tense environment of energy and the implementation of the concept of sustainable development of energy conservation and emission reduction remind people that energy conservation is very important in today's society. Industry insiders said that the "entering the city" of solar energy conforms to the construction trend of green ecological city and is also the life needs of the majority of urban residents, but the key to occupy a stable market position is to meet the needs of urban users.

"After moving into the new building, the solar water heater used to be useless. This time, let's see if there is solar energy that can be installed on high buildings." the reporter met Ms. Zhou who came to buy solar energy during her visit to the solar energy store. She told the reporter about her troubles when using solar energy. According to a person in charge of the store, there are many inconveniences in the installation of traditional solar water heaters in urban high-rise buildings, and they are not convenient to use, which makes many urban residents flinch from solar energy.

At the same time, the reporter found in the interview that the water tank and collector can be separated, and the flat-panel solar energy installed in different places is more concerned by consumers, and the innovative split design still caters to the hearts of the people. According to the analysis of insiders, the reason why split plate solar energy is highly praised by urban residents is that the original split design of flat plate solar energy makes solar energy look like a part of the overall building, which not only maintains the beauty of the building appearance, but also makes it more convenient to use. It not only solves the problem of "difficulty in entering the city" of solar energy, but also meets the wishes of urban residents to use solar energy.

"This flat-panel solar energy is good. The collector can be hung on the balcony. It is beautiful and practical. The water tank can be installed indoors and outdoors. There must be no problem installing it upstairs." after repeatedly comparing several solar water heaters, Ms. Zhou finally bought a Haier flat-panel solar energy after bargaining with the salesperson. "The titanium blue light energy gathering technology and patented 360 degree heat exchange technology of this flat-panel solar water heater make the heating efficiency of the collector up to more than 78% and realize 3D circulating three-dimensional heating, which can create a comfortable experience of constant temperature bathing for users," the salesperson said.

According to the industry research data released by the National Bureau of statistics, Haier flat panel solar ranked first in China with 12.92% sales and market share in 2012. In view of this situation, industry authorities believe that the construction of green and energy-saving communities across the country has promoted the development of the solar energy industry, but in order to win the attention of the market and satisfy consumers, we also need to focus on consumers' needs for innovation. Home appliance manufacturers must adhere to the user-centered principle and completely solve the problem of limited solar installation in urban buildings in order to show the style of leading the market.
