Flat panel solar water heater will become the future development trend

China's solar water heater market is developing rapidly. Industry insiders point out that flat panel solar water heater will become the future development trend because of its more safe and reliable, longer life, better combination with buildings and more comfortable characteristics.

Hu Guangliang, deputy director of China Solar Thermal Utilization Committee, director of Guangdong solar thermal utilization Committee and chairman of Guangdong five star solar energy Co., Ltd., who is participating in the international housing Expo in Beijing, pointed out: "the domestic solar thermal industry should be upgraded. Flat panel solar energy, due to its mature technology, strong pressure bearing capacity, low energy consumption and low energy consumption, should be upgraded It is easy to implement the integration of solar energy and building, and solve the shortcomings of vacuum tube. It will become the mainstream of the domestic market, and the new business opportunities of flat panel solar energy have appeared. "

We learned that China is the largest producer and consumer of solar water heaters. With the promotion and popularization of new energy and the progress and development of science and technology directly promote people's demand for high-quality life, vacuum tube solar energy has gradually been unable to solve all the technical and quality problems encountered in its large-scale application. In urban buildings, the bottleneck problem of vacuum tube products has become increasingly prominent. For example, the "Olympic Village" of the 2008 Beijing Olympic Games is known to the world as a highlight of building energy saving. Solar power generation and hot water system are used on a large scale. However, the solar water heater chosen is not vacuum tube solar energy made in China, but flat panel solar energy produced in Germany.

Hu Guangliang said that at present, in foreign countries, the market share of flat panel solar water heaters is as high as 90%, while in China it is only 10%, and the rest 90% is vacuum tube solar energy, so there is a large market development space. Due to the characteristics of vacuum tube solar energy, its defects have become more and more obvious, such as tube explosion, frost cracking, scaling and sediment deposition in the tube, leakage of sealing rubber ring, etc., which also directly affect the user's experience.

The international standard of flat panel solar water heater has clear regulations on its quality, technology and performance testing. Although flat panel solar energy requires higher technology content, there are still many domestic solar energy enterprises that can be competent for all kinds of projects that need flat panel solar energy. One third of the flat panel solar energy products of five star solar energy company are exported to developed countries in Europe and the United States. An Australian dealer alone sells more than 100000 square meters of five star flat panel solar water heaters in Australia every year. As the hot water supplier of the 2010 Asian Games, five star solar energy company will build hot water projects for Guangzhou Asian Games venues.

Talking about the current development of the solar water heater market, Hu Guangliang said that although the products in the market are uneven, in recent years, the state has successively issued some standards. Generally speaking, the solar water heater market is gradually standardized and improved.
