Flat panel to turn over
[REVIEW] a long time, our main markets abroad, such as OEM products in Europe last year the output value accounted for more than 30% of GDP. Because our products are mainly flat-panel solar water heater, and the current domestic market or in products. \"
Five Star Solar AG, Guangdong Chang, director of marketing students recently told reporters speech: \"For a long time, our main markets abroad, such as OEM products in Europe last year the output value accounted for more than 30% of GDP, because our products are mainly flat , and the current domestic market or in vacuum tube solar water heater products are the main. \"
According to \"China Construction\" reported that China\\ s 2009 market share in flat panel solar water heater is only 30% of the vacuum tube water heater is the mainstream. And with our different, Europe, Japan, solar water heater market is based on flat products, Portugal, Israel, Greece, Brazil and other countries is close to 100% for flat products.
For foreign-based flat-panel solar water heater because, in rural China Solar Energy Industry Association Professional Committee Luo Zhentao said, first, flat-panel solar water heater because of foreign pressure, long life, easy to form the secondary loop system, the second is easy to combined with the building, easy to install and the third is the system safe and reliable.
With the progress of urbanization, high-rise buildings into the mainstream of China\\ s urban construction. As high-rise building roof area is not enough, but to use the balcony or wall-type solar water heater, but easily broken vacuum tube, sealing gasket leak easily aging, the balcony or wall installation larger security risks. Why China\\ s solar water heater can still in the vacuum tube-based products it?
In fact, as early as the early 1980s, Yunnan, Guangdong, some companies on the introduction of foreign flat panel solar water heater technology, but it was due to some technical flaws, such as flat-panel water heater was required Operating temperature above 0 ?, it can only apply in the south part of the region. Coupled with antifreeze, pressure and other key technical limitations, and vacuum products in the price, maintenance cost and other advantages, vacuum tube products have gradually become the mainstream market.
Beijing Solar Energy Research Institute of the original hope was that the Yangtze River, China\\ s solar water heater has been in use in direct heating solar collectors traditional methods of water, while the flat plate solar collectors in the water to freeze not only affects the normal operation of the collector, and the resulting tube easy to split up. The vacuum tube products for the winter without draining the water situation in the basic non-frozen or not frozen, and therefore to be welcomed. Followed by the all-glass vacuum tube water heater production costs nearly 10 years significantly reduced the production of flat plate solar collectors are not much lower cost. \"But now a new generation of flat panel solar water heater has been using a secondary circulatory system and antifreeze, to solve the problem of low-temperature operation.\" Zhang played Health, told reporters after the Mohe and other cold regions of the experiment, a new generation of flat panel solar water heater can even minus 40 ? work.
On the other hand, as technology advances, the use of copper pipe flow, the production of flat glass cover using solar water heater, the load-bearing capacity of up to 1.5 tons, combined with greatly improved with the construction, especially suitable for installation on the balcony and exterior walls, and water pressure, corrosion, and gradually show the relative advantages of traditional vacuum tube water heater.
Out of the water heater plate optimistic about the prospects, including five-star, Haier, sun, rain, Aucma, etc., companies have invested in this project, and after another product into the market. According to China\\ s Rural Energy Industry Association Professional Committee of solar energy, said Luo Zhentao, the last two years, flat panel solar water heater in the 46% annual growth rate of development.
\"China vigorously promote energy conservation policy and the development of green building solar panel solar water heater to bring new opportunities, but for now, its marketing is facing some obstacles.\" Zhang played Health told reporters: \"On the one hand, some construction design department of the flat panel solar water heater is not familiar, do not know how to do with building the perfect combination on the other hand, many consumers are used to the traditional vacuum tube water heater, solar water heaters are not familiar with the Tablet, which also requires further consumer education to help them familiar with the product, better use of the product.
