Embarrassed phenomenon analysis of solar energy application1

In recent years, solar energy has been shows human its incomparable superiority, as a representative of the clean energy in the 21st century, apart from solar street light, solar, flat panel solar water heater is hugely popular in many countries around the world, its market share in many countries accounted for one hundred percent, its market share is less than 10%. Compared with vacuum tube solar water heater, flat solar water heater many strengths, combined with the building facade, ease of installation operation and maintenance, long service life and so on. Why application in our country, however, are so strange?

in the Chinese market, the vacuum tube solar water heater is to occupy more than 90% market share, even many brand solar water heater manufacturing enterprise is given priority to with vacuum tube type products, mainly caused by technology and historical reasons. In the nineties of the last century, when the natural cycle of flat solar water heater work above 0 ℃ temperature requirement, can in - compared with vacuum tube type Work around 10 ℃, have obvious & other; Shortcomings & throughout; , coupled with the production of vacuum tube type reduced year by year, the cost of the product to make consumers and manufacturers are willing to use vacuum tube solar water heater.

however, with the accelerating process of urban development in recent years, multi-storey and high-rise buildings have sprung up, on the formation of a vacuum tube solar water heater's installation and use of serious & other; Challenge & throughout; 。 “ Owing to lack of multistory buildings and high-rise building roof area, appropriate USES the balcony or south wall type solar water heater, and vacuum tube is easily broken, o-ring seal aging easy leaking, balcony or exterior wall installation safety hazard is very large. ” One of Beijing famous solar energy enterprise management personnel, according to the frosty winter when vacuum tube easy season, almost can't see them in the company, because they all ran to the on-site maintenance.

in contrast, the technical progress of flat solar energy water heater in the market. “ Port using pure copper tube, plate adopts toughened glass production, the use of the secondary loop system and antifreeze flat solar collector, bearing 1500 kilograms, and not & lsquo; Fear & rsquo; Run at low temperature. ” Some industry insiders, & other; In the past two years, our country flat solar water heater at the speed of 46% annual growth in rapid development. ” In rural China, director of the solar energy industry association professional committee of Luo Zhentao also delivered a speech, flat water heater is especially suitable for large engineering project, now more than 10000 square meters of engineering in many provinces in China, are ready to choose to use flat solar water heater.

it is undeniable that the solar water heater domain & other; Throughout China phenomenon &; The existence of the cause of the China's national conditions, and the personage inside course of study on new product publicity to promote the cause of the poor. However, as the industry's efforts, and users' attitude toward change, solar energy field of the so-called & other; Throughout China phenomenon &; Is expected to disappear at an early date. Solar energy lamp, solar garden lamp also is being widely used.
