Zhuhai Xingye Energy Saving Technology Co., Ltd. and Hunan Xingye Solar Energy Technology Co., Ltd. Deputy General Manager Liang Jianying [Liang Jianying]: I have been working in this industry for only a short period of time, only 11 months. Through my contacts with the industry, I talked about my experience and talked about it. Our sales problem. There are several aspects of touching the flat panel. There are several aspects. The flat panel is not what we think of as a North-South take-all. Second, the flat panel has a problem in terms of heat dissipation compared to the vacuum tube. The professionalism of the third marketing team is very worthwhile. The problem of importance.

Let me talk about my views on these three issues.

The current annual production capacity of the tablet is 1 million square meters. We used to be primarily photovoltaics and curtain walls. After the light and heat started last year, we explored and explored on this road, like our big brother company. I feel that we have limitations in our entire industry. This year's sales does not exceed 100,000 square meters. For our sales, the problems we encountered in the current market are like this. Our company did not make retail markets, mainly for the engineering market, because we started with projects. Recently, we have changed our direction, and we have truly developed the integration of the tablet and the entire building. That is to say, our light and heat market should be widely used in architecture. Although we call this topic every day, it is very difficult to really apply it to the construction field. We are a Class A design agency for glass curtain walls. At present, our company is trying hard to integrate our flat panel with our building curtain wall and building. At present, in Hunan Industrial Park, we will realize this idea. We will try our best to bring our light Hot plate combined with building. Today, the solar energy on our balcony wall is not hung outside. It is integrated with the entire fence. In the future, the road our company is going to take must be integrated with architecture.

Second, why can't we eat all over the north and south, flat plates are sold all over the country, and the weather in the north (low temperature) is very worrying. We may consider this issue in the future. We have done such a project in Beijing and found that the tablet is not effective now. What really matters is the low-temperature air-source heat pump, which runs very well. However, the current heat of the flat panel cannot meet the requirements of the design. This is a question worthy of reflection in the future. Now, when it is applied in the north, our company is very cautious. We hope that we can make a hope project. We have two or three big projects in the north. This kind of project is very prudent in application and we hope our products can really Give us a good role in the terminal.

Third, we currently have problems with the marketing team. All manufacturers will encounter such problems in the future. How to establish a professional marketing team? I find that today's marketing team, including future home appliances including other industries, our solar marketing team is a poor marketing team, we did not put us Something completely introduced to the customer, on their own requirements, I hope my marketing staff never professional go to the professional, this is my first request, what should I do? All salespeople from 2020 must be technically advanced; second, they must be specific. Since it is doing flat-panel, air-source heat pumps, it has strengthened the overall professional training. Third, we hope that we combine our expertise with our assessment mechanism. Xingye has just started in light and heat, and is particularly looking forward to Xingye inheriting the good aspects of the older generation and carrying it forward in the light and the heat, so that our entire team's ability or responsibility in the community can be better strengthened. thank you all.


Qixin Solar (Tianjin) Co., Ltd. and Tianjin Jinba Energy Environmental Protection Equipment Factory Chairman Qi Xin [Joint Heart]: I am very pleased to sit down with you again. As a veteran of the tablet industry, I am very pleased to see the conference gathering focused on the tablet. one class. My feeling is this: First of all, the coating is really critical. This is a bottleneck in the development of flat plate collectors in China. For this reason, many companies in the industry have also made a lot of efforts to solve this problem. The most successful is the anodic oxidation of samp, if it is really good, the performance is possible, but there is a problem, can only be done on the track, the future pressure, leakage still has some problems, In addition, anodizing has caused many problems in Yunnan. It is not the original technology. I personally think that anodizing will slowly be limited to a certain extent. We also use some black chrome. Black chrome is the mainstream of the market, and the performance is doing well. However, black chrome has a fatal problem that is contaminated during the production process. In 2002 and 2003, we did not understand that European development could not use black chromium. Europeans are more advanced than we are. Whenever pollution occurs, it is on the polluted earth. If I use this thing you are polluting the earth, So many countries are limiting. At present, China is not so strict in this respect. Black chromium is still a mainstream product. However, with the awareness of environmental protection being deeply rooted, pollution problems in the production of black chromium will restrict its development.

I personally feel that we look at various industries in the country, Europe and the United States are still in the front, including glass tubes, and the United States was the first to do it. In fact, until now, Chinese cities have also eliminated glass tubes. This may be an inevitable process. In the future, China's coating construction will go in this direction in the future. There is also a higher-end nanoscale coating. A doctor from the Taiwan Academy of Sciences went to talk about it and would like to push it at home and abroad. The price of this new coating is also relatively low. Introduce the situation to see, quantify the production is lower than the current electroplating black chromium. I think that in the future there may be a certain market for these four kinds of coatings. Anodic oxidation and electroplating of black chromium may occur in the low-end market.

Topic 2 German Anlu Xu Feng: As long as the Chinese government does not ban black chromium and anodizing one day, because it is polluting the environment after all, it is also good from the aspect of efficiency, although the emission rate of black chromium is relatively high, the anodizing efficiency Although worse, the current advantage is price, although the blue film is good, but also have to see clearly, the price is a little more expensive, the future development, if the country does not have a policy introduced, several products will also drive away a section of the road, it is estimated that this section is not It will be very long. I think that China's environmental awareness is already very strong, and all industrialization is constantly upgrading. We must upgrade every day in the country, and other industries are doing it. Now all the surface treatments basically use vacuum. Instead of plating, this traditional plating method was quickly eliminated. In the long run, Blue Membrane Europe is also trying its best to lower prices. In terms of future development, there is still some room for blue film price reduction. The nano-coating has absorption and emittance that is slightly inferior to that of the selective blue film, and its performance is similar to that of anodizing. However, it is very environmentally friendly and its strength is extremely resistant to corrosion. This is even better than black chromium. Secondly, black chromium, the corrosion anodizing is the longest, but now the four materials are still there, but hope that the domestic counterparts should pay attention to the development of the world, because Europe may currently be a new collector, all All of them are plastics. The benefits of plastics are cheap, light and easy to install. This is the real material in the future. That is, one day, the selective coating on plastics will be the best in the future. Advantages: Cheaper prices , blend into one. I hope that China can catch up in this area too. I feel that I can't always follow it.


Hangzhou Oufan Energy Technology Co., Ltd. Yu Qinyong [Qin Yong]: We have been doing flat panel solar for nearly 4 years and have been doing this industry. And our position is to do engineering, so we have some of the issues we just mentioned. Experience. In 2011, we started from scratch. Nearly 3,000 sets of villas and craft solar energy systems were installed in 2011. All of our systems use blue membranes. At present, our own production equipment is also laser welded and used by our so-called developers. Fancy. The key issue I just mentioned is the blue film I think is the better direction in the future. How to reduce the price requires the coating companies to do more.

For the engineering market, our approach is to emphasize design, first communicate with real estate developers and design institutes, and from the design point of view, first solve the entire system plan. After solving the problem, arrange the production. After the production is completed, there will be an own installation team. The entire industrial chain is completed by itself. Finally, in order to solve the developer's safety and maintainability of the entire solar energy system, we have also developed a remote monitoring system, which is more reliable. All current projects are concentrated in Hangzhou, Hangzhou is relatively strict implementation, must be on the solar system. From the big picture, the tablet should be able to replace the vacuum tube. I feel that our local companies must have certain advantages for the services around Hangzhou because everyone is still worried about quality issues and after-sales services. As long as the maintenance is done well, this matter can still be done well. I think we must solve the entire maintenance problem technically, because many people do not trust.


Deputy General Manager of Jiangsu Raymarine Group Co., Ltd. Ma Yifei, Deputy General Manager of Jiangsu Rayon Group Co., Ltd.: There are several feelings in using the tablet. One is in the process of solar energy entering the city. From my judgment or our group's judgment, the tablet is definitely A mainstream, which brings an explosion point or growth point to the entire industry. This round is always an era of flat world. We used to talk about solar home appliances to the countryside, and solar energy is the countryside product from the very beginning. Focusing on the countryside, in fact, we now face the problems of the entire industry, how to enter the city and how to go to the sea and enter the city. The tablet plays an important role. I now look at the reality of the entire market of our group. From our group, we probably use the tablet. There are 200,000 square feet. If we really want to enter the city, we really need a lot of improvements in our products to meet the market. Just now we discussed more about the coating problem. The coating problem must be solved, especially the thermal insulation problem. Sealing problem, because I am a medium-temperature consumer, I use the overall feeling of the market feedback to give my opinion, flat protection And especially the sealing problem, how to get the plates were incubated, how to make better seal, is thought-provoking questions. I would like to remind us of this industry. I am full of infinite love for the tablet industry. I think the tablet industry is promising. In addition to the coating problem, I earnestly ask the manufacturers and producers of flat plates to pay attention to the insulation and sealing properties in addition to the absorption rate and emissivity. I participated in many flat-panel projects and I can't bear to look at it. We must do our best to persist in doing so till now. We must do the best and do the best. For over 30 years of history, my advantage is to be a confined water tank, but I will not do flat plates. I will certainly choose the right companies to support us. I suggest that our industry, in addition to studying coating problems, should study its sealability and heat preservation.

Beijing Solar Energy Research Institute Co., Ltd. Cao Zhenshan: History of the development of the tablet. Several company leaders have said that the tablet was introduced since 1986. We have been using it since now. Since we introduced the Canadian production line, Yunnan Province has copied nearly 10 production lines. , but now have been eliminated one after another, for whatever reason, you may all be quite clear because the tablet has its use conditions in the past because of the problem of frost resistance, but now it is not until the Spring of flat solar energy, it is objective to tell everyone before us that For a period of time, testing of various well-known companies' flats made us feel very disappointed.

Second, what should you do with the tablet in the city? Home or project, what your home does, what your tablet does, don’t follow the trend blindly, and don’t have experience without experience. We launched a return visit to sangpu for more than 25 years. In the vast majority, we are now also studying blue film and magnetron sputtering. The blue film has its own defects, its timeliness and durability. Everyone will feel in a real professional laboratory and we will launch it as a flat panel. People and holders for so many years, we now have a point of view, do not have the experience as far as possible, you can do to find us OEM, we can provide excellent quality products for various manufacturers.

Third, what does the flat plate do for the city? We think that we have participated in the housing guarantee conference and we have secured the most prominent slogan: safety, durability, adaptability, and economy. I hope everyone will consider branded and experienced companies to cooperate in consideration of the flat coating, durability and service life.


Song Hao, Chairman of Shandong Haoke Solar Technology Co., Ltd.: We can push forward our energy and look forward. As a vacuum tube, we used to make a vacuum tube ten years ago. When the vacuum tube was black, why? Black is blue, and blue is not better than black. Second, from the solar bracket, the earliest was aluminum alloy, and now why not use aluminum alloy. Market orientation may play a decisive role. My point: reasoning backwards and looking ahead. Because of profiteering. The same is true of the computer industry. It was chaotic 20 years ago. I think this is a market elimination mechanism. There is no fuss. Everybody should be market-oriented.


Chairman of Jiangsu Oster Solar Co., Ltd. Dai Hongbing [Dai Hongbing]: Just now, the luminaries had said that we did the terminal. It took a year last year and traveled all over China, including the cooperation with Beijing Sangpu. We once wanted to be in the south. The manufacturers and suppliers of flat plates awakened overnight and gave up. Why did you give up? I did a few years of solar energy and I was very tired. I have been doing real estate since 2008 and I have been doing real estate for 4 years. I feel solar energy. Not so much fun. Why do we all make mistakes in the rules of the game? Everyone is thinking from their own perspective, including the questions that today's tablet experts are discussing. How many consumers understand? It is a competition between the manufacturers and the equipment. Last year, there were more than 3,000 flat-panel projects, a stand-by, where your project was, 500 kilometers from my local area, I saw a project in Suzhou and I was shocked. People's real estate company house has not yet delivered, flat triangular iron All of them rusted. A large demonstration project was done in Zhejiang. The slabs were really bad. They went to the same flats in Guangdong, North and South. The same specifications, a difference of 500, and I engaged in sales, how could such a big gap? Later, I discovered that many manufacturers are not researching quality, not researching and supporting services, and researching to reduce costs. I feel that this game is really wrong, research technology is better for technical research, and you say that blue film is a good price. To be a little higher, as a manufacturer, I hope the price is better, the quality is better, and the service is good in the later period. Today, the most talked about is the tablet. The tablet is not blue film, black chrome is good, you are still not on the tablet, or not In the past two years, the high-rise buildings in the city have been getting higher and higher. The vacuum tubes have caused a lot of doubts about the safety issues and brought many opportunities to the flat panel. Later opportunity will be a nightmare, the opportunity to more easily and may die more quickly for our industry, the dead will be more disabled. I used to communicate with several real estate companies in Shanghai. People said that it was not fun. I could tell him many times. I would like to co-operate with you and tell me that you have given me a successful case. Solar manufacturers we are here should not blindly pursue, we should do what we are good at, for example, no matter what, do a good job of quality, the terminal market to do a good job of sales, OEM manufacturers do not cut corners, I believe this market will be more and more The better you do. We first consider the issue from the perspective of consumption, consider the issue from the perspective of the dealer, do not stand on their own perspective, how many million square feet are sold today, no one sells to whom, who is our money, how do we put our Doing a good job in the market, doing a good job of service, and doing a good job in quality are the most crucial issues.


Bonn Solar Technology Co., Ltd. Deputy General Manager **: We specialize in the production of flat panels. Our company is the source of equipment and started trial production in August. There is no separation between the north and south of the tablet. There is no separation between the north and the south. There is heat in the irradiation. The key problem is that the horse always says, how to seal it well, and how to keep the insulation good, as long as the seal is good and the heat is good. Although we were late, we sponsored a project in Heihe, and it has been operating at minus 20 degrees until today. Our board is a full-automatic assembly line production. It can be said that it is the first automated production line in China. We design the ability to produce one board in a minute. Our board has abandoned the traditional board. The insulation layer is the overall polyurethane foam. Our sealing technology It is a globally protected patented technology. thank you all.

Mr. Tan Junyi, Director and Director of Thermal Energy Research Institute, China Industrial Solar Energy Technology Holdings Co., Ltd.: For us, the quality and safety are the first from the consumer's point of view. From the technical level, this year's customers have requirements and can’t do 400 RMB. On one board, I can't do it. According to the cost of own quality assurance, unless you cut corners and anodize the coating, you can, but how long can your product make in the industry? I can think of a way, but the technology of this method takes time. I want aluminum water pipes to replace copper pipes, but it will take time for us to meet consumer demand. Do not mislead consumers by price. You have cheated once and there is a misunderstanding of our entire industry. I believe that it is very unfavorable for us to develop. Here, we urge everyone to be a long-term development target company, and seek truth from facts. The profits and technology that it bears are a promise to consumers. Don't talk about it.

Yang Xingjie, research and development director of Five Star Solar Co., Ltd.:

Topic 1: An increase of 43% in 2009 and an increase of 50% in 2010. I think the five-star experience is not less than 100%. Our sales exceeded 500,000 square meters this year.

Topic 2: Regarding the coating, three standards were drafted in 2010. Among them, there is a standard for the technical standard of the plate collector and the kind of film involved. Tablets and tablets are not the same. Tablets are divided into third and fourth. Technology gaps in the 50's may be summarized in tablets.

Topic 3: Laser and Ultrasonic Welding. Many problems have been discovered in laser applications. Domestic laser welding has advantages and disadvantages.

Topic 7: I think it's definitely a good thing. I'm very much in favor of Cao Zong, the North Taizong. Don't blindly do it.

Topic 8: About the market. On July 26 this year, a company in Hebei issued a bid. At that time, they chose to control the company. They did not agree internally and all the leaders were not unified. These 13 companies are all well-known companies. They talked about products and defended their opinions. I received 19 votes on behalf of Wuxing Solar, not because. I say good because the product is convinced because my product is safe, beautiful, efficient, and safe to use. Everyone has a misunderstanding of the tablet: 1 North-South issues. The fact that the high-end tablet is used in the north is better. Why? In 2004, I went to Mohe and did experiments to prove that the tablet can be used in the winter. At minus 39 degrees, I can reach 71 degrees. 2, on the issue of heat loss. Many people think that heat loss is high. We have done many experiments and the average heat capacity is higher than that of vacuum tubes. 3, flat-panel cost-effective, in fact not originally comparable, flat plate pressure and vacuum tube pressure.

Wang Zhuxiao, deputy director of Guangdong Wanhe Domestic Marketing Business Center: We are now only doing flat panels. We are not exploring for a long time because we are working on gas appliances and also have heating boiler business. We have integrated with European heating companies. Throughout the process, the entire industry has found that compatible phases, especially flat plates used in domestic hot water and small heating, are still ahead of Wei Neng, etc. The most important reason is that they can realize ground source heat pump and gas-assisted heating for the entire efficiency. Promote. In this regard, Wanhe vigorously develops junior high schools for the use of solar thermal energy. After 2017, during the process of statutory phase-out equipment upgrades, a single product will be phased out and the gas-fired heat pump and flat panel solar energy will be highly efficient. At the same time some inspiration for the future application of this industry.

Regarding the market, I also said that I feel that at this stage, the trading rules for sales of solar energy products in the Chinese market determine that if solar energy is used as a flat panel or vacuum tube, if it is sold as a single item like refrigerator air conditioner in a hypermarket, it is very poor. The end of the product will be out, I said it is not possible, because just a lot of colleagues are also talking about, ordinary consumers to promote technology and quality is not professional knowledge, if one day must be placed in the United States, Suning and other such products to sell At that time, I think that everyone’s ideals can be achieved. So, at this point, regardless of the new or old brothers who are doing well, as long as engaged in the solar industry there must be such a mentality, it is possible to win in the chaos, there are also May be an innocent victim.


Xu Guohong, chairman of TMC Xizi Instrument Technology Co., Ltd.: We have been instrumenting for more than ten years, mainly around vacuum tube domestic solar water heaters. We are also very concerned about the development of flat panel solar energy, and we also feel that flat panel solar energy has developed very rapidly in these two years. Rapidly, I think that any solar hot water system control cannot be separated from the control system. It makes us feel that the flat panel solar control system is a bright spot for a new development market in the future. From the second half of 2009, we began to develop a flat panel solar instrument control system. Our company held a conference for a flat panel solar controller. We now use the tablet controller for pressure-bearing, non-pressure-bearing, and also for villas. , Sewage, Wired, Wireless, etc. In other words, there may be several points where the control points need to be controlled. We have adopted some new infinity sensing technologies that take into account the fact that engineering wiring is not very convenient.

Yunnan Yuxi Xinghong Solar Energy Equipment Co., Ltd. Representative: I was engaged in solar energy for 92 years. Under the leadership of Sangpu Solar Big Brother, I joined the flat panel solar industry. I am very grateful to Samp, who has brought me to a sunny industry. We have always played a price war and called it. It was originally a very good product. We have done it badly. I apologize to consumers on behalf of all employees of the company. In order to realize this, we worked through cooperation with Australia and other companies in the processing of flat plates, and also through a company in Beijing. We helped him to produce and communicate with him. I asked him if there is any cold and hot place in Australia. , how to put this product in the cold uncomfortable, the cost will be very high, I am now very clear, I think that in the solar industry, the positioning of their products is good, and now we reposition our tablet, we must do It does it well. With the development of the future must be the momentum of the tablet, I hope everyone here seize the opportunity to position their products.


Jiangsu Xinshinshen Solar Energy Co., Ltd. and Jiangsu Xinhanshen Contract Energy Management Technology Service Co., Ltd. Zhou Lianxing, Chairman and General Manager: Contract energy management, two to five years.

Bonn Solar Technology Co., Ltd. Deputy General Manager **: Before we entered the solar industry, our group company had already established a cooperative energy management company. I strongly agree that foreign contract energy management is financial support and must have finance. If there is no finance, Any contract energy management replenishment is unaffordable. The financial support of contract energy management is targeted at companies whose projects are not targeted, with project benefits approaching BT. There are also achievements in the contract energy management. Industrial Bank's energy under the contract is **80% based on the size of the project.

Li Yongquan, chairman of Yunnan Yitong Solar Energy Technology Co., Ltd.: Yunnan Yitong has been doing flat panels for 17 years. In fact, we started doing flat panels. The tablet that I was told to do was very low-end and primitive. Yunnan may use solar energy very early because of climatic reasons. To be honest, solar water heaters are very effective in Yunnan. Even if the quality is poor, the use of solar water heaters is not so obvious. I started to work on flat panels and now I have vacuum tubes. In my opinion, the future should still be the world of flat panels. Why, flat panel life, and the combination of buildings, thermal efficiency, safety, and many other factors determine that it is a very good and durable one. product. So the future should be flat world, the key endeavor is, what kind of tablet is definitely not an extensive, original, low-end tablet, but high-end. We have more South Africa and five stars this year and participated in the solar energy exhibition. The five-star tablet is very good and worth learning. thank you all.

Changzhou Zhao Erjin, Chairman of Solar Energy Equipment Manufacturing Co., Ltd., said: I do not produce flat panels, nor do I produce vacuum tubes and do my own brand culture.

First, marketization. Everyone speaks on behalf of personal views. Two people talk about the same business. Your opinion and my opinion, the final point of view make marketization conclusive. Everyone still thinks in their own minds, whether they are vacuum tubes or flat panels. China's national conditions should be brought into line with marketization, and everyone should adjust their own standards.

Second, professional people do professional things. Copper and aluminum, new coatings, etc. Professionals do professional things, can integrate your resources, we must use your advantage.

If you have a flat panel or a vacuum tube, you have to set your own brand.

Shenyang Xinjinbo Vacuum Tube Coating Co., Ltd.: The most concern is the problem of durability and product performance. Because we have been making more than two months, we will engage in some very professional organizations. We will also make these products a long-term test. . thank you all.

Xu Xiuhua, General Manager Assistant and Marketing Manager of Wuxi Hirute Solar Energy Technology Co., Ltd.: The company has its own brand and emphasizes internationalization. Our own network, each of our countries, Europe, the Americas, and different countries, according to the needs of customers, through the Internet sales of solar energy, has now played a very big achievement, thank you all.
