On the freezing measures
[REVIEW] northern s often such a failure occurs: in winter the temperature is low, the water heater back to the water frozen into ice, can not flow, causing water heater can not be used, the inconvenience to people\\ s lives. This paper on the causes and prevention of such failure to make a brief rule of measure.
Northern Solar Water Heater often such a failure occurs: in winter the temperature is low, the water heater back to the water frozen into ice, can not flow, causing water heater can not be used, the inconvenience to people\\ s lives. This paper on the causes and prevention of such failure to make a brief rule of measure.
First, the reasons for failure to form
Failure to the environmental conditions: the northern region in winter, especially in cold areas, resettlement, water heater return pipe (the pipe) from the flue or through tube wells.
Figure 1 shows a diagram of the formation of water heater failure, this failure is due to the formation of bends in installation pipe, some pipe against the wall, resulting in ice.
Figure two reasons for failure analysis of the formation is as follows: In winter, the outdoor temperature is low, combined with adverse external wall insulation, wall, wall temperature is below 0 ?, water pipes near the wall, but also speed up the transfer of heat, so that the pipe temperature gradually decreased. Tube in the flow of water though the water temperature has dropped, but not frozen. Most water heater is not used at night, a long tube of water at rest, the water temperature gradually decreased, until the ice. When the full pipe cross-section of Icy and has a certain length, then the water blocked, water heaters will not be used.
Second, the failure of several solutions
1 Remove the water at one end, if we determine the approximate location of the ice, then remove from the ice closer to one end of the wire through the pipes, and gradually forced to make ice activities or broken, as long as there is very little flow through, which will be gradually melting ice, troubleshooting.
Using this approach should be noted that the question is: not sharp wire ends, so as not to puncture the pipe; if the interior end of the pipe removed, once the troubleshooting, water heater in the water will quickly drain, causing water damage, to be prepared in advance; If you remove the outside end of the pipe, the water heater tank will quickly spilled outside, should also be wary.
2 by the two ends of pipes stuck, hard shake and stretch, water in the ice due to broken or bent by the vibration of the pipe deformation by stretch straight ice broken, troubleshooting.
If the pipe is longer, the success rate of this approach is not too high.
3 to the tube-wells (flue) heating the air within the injection, usually from the lower part of the injection, the ice melted, troubleshooting.
This approach requires a heating and air-injection device.
4 block area to find water in the pipes to direct external heat to melt ice.
This means that the equipment for water, if water through tube wells (flue) is difficult to implement, difficult to find the first positioning block area, the second is affected by tube-wells (flue) limit, unless the destruction of tube wells (flue .)
Third, the preventive measures
1 For new buildings, to consider increasing the wall insulation measures, in particular parts of the tube wells insulation measures, so that the temperature inside the tube-wells will not be too low.
2 for the old building, installation of water heaters if the water in the distance is not long, you can use with the tropical over the whole line. Distance may not be suitable for use with tropical insulation of pipes, water pipes can be installed close inward, away from the wall, as far as possible through tube-wells, the water channel near the inward, away from outside walls, as far as possible through leaning against the wall of tube-well wall, this approach can often achieve the desired results.
3 other ways: (1) heating pipe through tube-wells, tube wells to improve the temperature; (2) Open the water heater at night to put out a small amount of water taps, water pipes inside to avoid freezing. However, this approach is only temporary measures, not long-term use.

Application of enamel interior to the inevitable trend of
[REVIEW] advocated the construction of national saving, energy-efficient environment, China\\ s solar water heater industry, gradually the rapid development of the road, basically formed a relatively complete industrial system, to enter the international market situation has become more evident.
Construction of a conservation advocate at the national, energy-efficient environment, China\\ s solar water heater industry, gradually the rapid development of the road, basically formed a relatively complete industrial system, to enter the international market situation has become more evident. In 2009, total sales of solar water heaters close to 65 billion solar manufacturers around the country more than 5,000. In particular, there are already more than 20 provinces and cities to promote the introduction of a s mandatory policy, the city needs new 12-storey building supporting the promotion of solar water heating systems, and energy-saving targets in high-rise buildings also have higher requirements .
Solar thermal industry trends
With the rising level of consumer spending, especially in the real estate business for requirements continue to improve and promote use of solar thermal upgrading of the entire industry, an important issue. Industry perspective on the current status quo, the direction of the solar industry to upgrade the following main aspects:
In consumer demand, the solar thermal industry need only look for \"endothermic\", \"insulation\" effect to the \"healthy water\" demands to upgrade, many consumers are increasingly health-conscious life, increasingly required for solar water higher;
The way the system is running, the solar hot water system needs from the \"exposure to non-pressure type\" to \"pressurized\" system upgrade, in order to meet consumer demand for hot water pressure sub-requirements;
Complementary technologies in the photovoltaic, solar hot water system needs from the \"non-electric heating device\" to \"electric heating to achieve optical complementary\" other direction, in order to solve the winter, rainy day water shortage;
Parts of the product, the solar hot water system needs to \"stainless steel liner\" to \"enamel interior\" upgrade, in order to continuously improve the corrosion performance of the solar interior, to improve product life and water quality;
In the production of equipment, from workshop \"screwdriver\" type device to the fine, modern equipment upgrades, CNC punching, laser welding and other modern equipment needed to promote the solar industry;
In engineering, the need to \"support solar energy and building simple\" to \"building integrated solar energy to achieve the perfect combination of\" upgrade, split pressurized hot water systems, solar energy products such as the balcony wall and building a harmonious shape is easy to complete, as the product of choice in high-rise building;
In services, solar energy companies need to \"install, repair services and other simple passive mode\" to \"Installation, maintenance, consulting, design, security, cleaning and other active service model,\" the upgrade.
The limitations of stainless steel liner products
\"Liner\" is the heart of solar water heaters, their characteristics affect the overall life of the product. As the stainless steel liner technology easy to implement, production equipment, R & D costs are lower, the market for more than 90% of the product is used in stainless steel liner. Stainless steel solar energy in the \"open\" state without electric heating, the use of better, and longer product life, which is the rapid spread of solar products to advantage. But once installed electric heating devices, especially the use of a pressure-type operation, stainless steel liner products have significant limitations.

Education is not high but it is the first person to patent
[REVIEW] his is a return of migrant workers, with their wisdom and study the spirit of the invention of \"new ,\" and won the national patent, patent in our province was the first person of this country -
Long County farmers Dongkeng CMC Zhang Gu Duan Li Jinhui, 36-year-old junior high school graduation, although he is not well educated, but the mind active, there is a fresh and aggressive drilling.
After graduating from junior high school, Li Jinhui in the home for three years engaged in auto repair, 1997, came to a hardware store, Guangzhou City, Guangdong Province, workers, mainly to undertake hydropower projects. Li Jinhui childhood love of physical, mechanical, utilities, water and electricity industries very much at home, and soon grow from the general staff for the project to repair the master, he took more than 10 apprentices this industry is very prosperous business. Hard-working smart Li Jinhui been appreciated by the boss, the boss sent him to the urban area of ??Guangzhou professional training base for further study, to further improve the professional level and ability.
In February 2002, workers of the Li Jinhui long to start generating their own boss ideas. First proposed, he was a bit worried for fear the boss\\ s opposition. However, the boss that not only did not object but after much support, but also for its secured loan and purchasing channels, available to all customers Li Jinhui. Soon, Li Jinhui acceded to invest 10 million yuan in Guangzhou, opened a hardware store. As the empirical adequacy, skillful, Li Jinhui\\ s hardware store business is very good, with an annual income of more than 10 million.
From workers to entrepreneurs, from marriage to children, unknowingly, Li Jinhui life outside of work for 10 years. As the business is busy, Li Jinhui home and their families less and less, the concept of homesickness growing. \"In recent years, rapid development of the South Long home, has changed dramatically, back to business is the same!\" Persuade the family to Li Jinhui heart. In 2008, he went back home taking the time and found that the South is full of dragons store, full of plants, popular, many business opportunities. Li Jinhui great touch, rooted desire to venture home. In May that year, Li Jinhui South County Waterfront Park in Long rented store, opened a hardware store, dry good line of work back to their own. Six months later, Li Jinhui see good prospects for solar water heater industry, began a solar water heater sales agency work.
In the solar water heater sales agents work with the customer to ask such a question: rainy days, can not heat, no water to put out, and sometimes the whole family travel, a few days without solar water heater, the water stop too long in the vacuum These two situations lead to solar water heaters in the water is not fresh, the skin will be sensitive to wash the itchy, leading to sub-health. \"This problem can be fixed?\" Li Jinhui fell into deep thought. He remembered the previous repair principle: get out of gasoline, it can suck through a straw out of the vacuum tube solar water heater works here can it? Light to not work, Li Jinhui start the experiment together. Open water heater vacuum tube devices, homemade siphon placed inside, repeated experiments, developed after more than six months, and finally succeeded in developing this new product out. The new products using the siphon principle, the vacuum tube solar water within several days in cold weather and the state still do not use automatic emptying, compared with traditional solar water heater with water is more pure, more hot water, vacuum greater thermal conductivity three major advantages.
\"Invented the product, but you just a junior high school students, their personal statement alone we believe that?\" His wife\\ s words reminded Li Jinhui. \"It declared national patent.\" A bold idea to take out. Says it will do, Li Jinhui went to Beijing to declare the patent, is supposed to be a long time to declare the results, but Li Jinhui company is involved in the national energy saving projects will be given priority. The end of 2009, Li Jinhui declare success. Holding the hands of national patent certificate, Li Jinhui quite pleased: their own labor was finally recognized by the State.

Heating caused by solar water heater standards battle
[REVIEW] may, In the near future, there will be two names sound similar to the standard at the same time placed in front of the solar water heater business – \"Live auxiliary energy system technical conditions\" and \"with a solar heating unit The special requirements of storage-type water heater. \"
Perhaps the near future, there will be two names sound similar to the standard at the same time placed in front of the solar water heater business – \"Live auxiliary energy domestic solar hot water system technical conditions\" and \"water with a solar heating unit water heater specific requirements. \"
The difference between the surface
\"Charged auxiliary energy domestic s and technical conditions\" (hereinafter referred to as \"auxiliary solar power technology\") under the jurisdiction of the national solar Standardization Technical Committee, as recommended national standards. The \"unit of heating water with solar water heaters special requirements\" is GB4706.12-2006 \"Household and similar electrical appliances Particular requirements for storage-type water heater,\" the normative, as GB4706.12-2006 has been there is an appendix, so the development of the appendix is ??also known as Appendix BB. Currently, two standards have been submitted for approval to enter the stage.
Draft for Approval in the two standards, auxiliary electric energy for domestic solar hot water system is defined as: the solar collectors, heat storage tanks, pipelines, electric auxiliary heater and controller, etc., also known as auxiliary energy charged s, hot water storage tank for heating water installations; and solar heating unit with a storage-type water heater is solar water heating and electricity for the energy, the two functions can work simultaneously or one feature independently work storage-type water heater. These two seemingly different description, in fact, just the same thing from different angles to make the interpretation. Solar water heater companies interviewed indicated that the two standards for a product, but the starting point is different.
In addition to different names, the company participated in the drafting of the standard are not the same. \"Electric assisted solar technology,\" the drafting of the unit by the 16 solar water heaters, including Sang Le, Huang Ming, northern Purcell, Pete, Hua Yang, Sunshine, Rongshida solar, Norit, Qinghua Sun, Four Seasons Mu-song, the United States large, brilliant, per liter, light, Ian Van and Temple, and the only water heater appliance company – AO. Smith form. Appendix BB of the drafting unit is mainly for the electric water heater companies, and large-scale solar water heater industry in several companies. As the reporter did not get a description of the preparation of Appendix BB, this can not be listed in detail in the company participated in the drafting, but, according to the standards of the enterprise to participate in those memories, the drafting unit including the United States, Haier, AO. Smith and other electric water heater companies, as well as Emperor Ming, Pete, Qinghua Sun and other solar water heater business. No wonder an industry joke: \"to develop\" power assisted solar technology, \"who are not familiar with electric auxiliary heating; drafting Appendix BB who do not understand the solar water heater.\"
Content of the different
Safety standards as normative appendix, Appendix BB is GB4706.1-2005 \"Household and similar electrical appliances – General requirements for safety\" and GB4706.12-2006 for additions and modifications formed. \"Electric auxiliary heating device with solar water heaters need to CCC, and CCC certification based on standards is GB4706.12-2006, but this is not considered when the standard in the development of the special nature of the solar water heater, so irrelevant. \"Beijing Tsinghua Solar Energy Development Co., Ltd. Vice President Huangzhe Lin said that\" the development of Appendix BB, it is hoped more suitable rules for the introduction of solar water heaters. \"
Appendix BB by reading the manuscript, the reporter found that the original standards in Appendix BB to make 20 more additions and changes, to modify some of the more concentrated the product structure. It participated in the drafting of the standard solar water heater business to reflect, the more intense is the debate was part of the structure. \"In particular, temperature and pressure valve installed on whether the discussion, electric water heaters and solar water heaters are not the same view held.\" Beijing Solar Energy Research Institute Co., Ltd., director of high quality even Kui said.
\"\" Solar power assisted technical conditions \"relating to safety issues, which mainly refer to the current provisions of GB4706.1-2005.\" Huang Ming Solar Energy Group Co., Ltd. Development Minister ZHANG Li-feng said. By contrast, the \"electrical\" reporter found that \"electric auxiliary solar technology conditions\" in addition to many references GB4706.1-2005 provisions, protection against electric shock, water level, electrical strength, leakage current requirements, etc., are related to GB4706 .12-2006 the Ordinance.
Demands on the difference
\"At present, in the city to use solar water heater market, about half of the products with electric auxiliary heating device.\" Solar thermal Professional Committee Luo Zhentao said. With the electric auxiliary heating device with a solar water heater market expansion, these products become the focus of the standards community, and the drafting of the standard game is the most obvious and most truly reflect the aspirations of all parties.
Discussed in Appendix BB is more intense in the temperature relief valve, for example. Appendix BB provides solar heating unit with a closed water heaters should be equipped with temperature and pressure-sensitive and temperature in the tank reached 99 ? before the start of the pressure relief device. \"In fact, install a temperature relief valve is technically very easy to do, costs not much, but it can cut off the way to solve the solar temperature and pressure problems.\" Lian Kui said.
Huang Zhelin that electric water heaters and solar water heater business enterprise debate is so fierce, the difference stems from the two products. \"Electric water heater companies attach great importance to safety, but the structure of the solar water heater has its own particularity, does not mean unsafe.\"
The solar water heater companies surveyed have said that the standards set in Appendix BB higher than the formal implementation of solar water heater industry may have greater impact, some SMEs may find it difficult to meet standards. No wonder a staff to participate in standards development, said: \"For many businesses, solar water heaters, Appendix BB seems a bit \\ harsh\\ .\" Provides a relatively \"moderate\" and \"auxiliary solar power technology\", is clearly more affected by solar water heaters welcome.
Respondents to the water heater business executives generally, Appendix BB\\ s security requirements are relatively modest, due to previous CCC certification of solar water heaters do not directly basis when the standard, after the introduction of Appendix BB can fill this gap.
In addition, an unnamed industry sources, the biggest difference between the two standard starting point is different, the content does not contradict the standard, two standards of evaluation which can not be better. Now the standards war, largely due to poor communication between the various standards committees caused. He said: \"The development of national standards, should be the integration of existing resources, so as to develop a consistent industry status quo and lead the development of the industry standard.\"

Overseas markets, not only is the focus of solar energy companies, China\\ s solar industry is also worth considering the coordinates.
Austria
Austria is the world\\ s largest and most developed solar markets in Europe, is one of the world after China\\ s largest producer of . Austrian solar water heater market in 2009, a 5% growth, the other main European market (such as neighbors, Germany and France) have a great fall.
Austrian solar water heater market in 2008, the growth rate as high as 24% in 2009, down by many factors affect the growth rate to 5%. The growth of solar market in 2008, mainly due to legislation and the support of various funding schemes, and fossil fuel prices rose sharply, making the residential and commercial installation of solar systems has increased significantly. In addition, the end of 2008 early 2009, due to disputes between Russia and Ukraine caused gas supplies to consumers in their homes with energy in an independent will. In addition to these factors, many consumers understand the solar system and the conventional boiler or heat pump heating systems combined. Solar energy systems in commercial and industrial sectors also contributed to the increased use of market forward.
In 2009, the Austrian bank credit system and strict international oil prices, a serious impediment to the development of solar water heater market. Some gas-fired heating stove manufacturers take advantage of this opportunity, through to the customer in the form of subsidies to replace old boilers with new, and thus increasing sales.
2008 and 2009 sales of flat-plate collector solar total Austrian market share of 99%. This is mainly due to the initial installation of flat products, low cost, because it is easy to install, these products are favored by installers and promotion; and vacuum tube collectors compared to inclement weather in the face of common non-friable (such as during heavy snow and hail); flat production costs low and profits high, so the comparison is affected by manufacturers to promote.
Absorbing materials in 2008 and 2009, copper is still the mainstream, increasing market share of aluminum, and stainless steel market in Austria is not how to use. Austria vacuum tube collector\\ s market is very small. In 2008 and 2009 sales of vacuum tube products accounted for only 1% of the solar market, sales of only 2% of total sales. This situation in the short term will not change much. Relatively flat-plate collector, vacuum tube collector prices higher, more fragile, but its higher efficiency than the flat 5% to 10%.
In 2008, Austria, about 17% of installed in new construction, this figure compared to 42.7% in 2007 down a lot. 2009 with a share in the new building will be reduced. This is because the reduction of Austria\\ s new building, one is installed in the existing building will be subsidized gas furnace.
In the past two years, as technology improved, solar water heaters in Austria is already available in many new areas of application, the application of non-residential construction also increased. Austria and Germany is different, mainly through the distribution of solar water heater installation company, followed by a professional heating and renewable energy wholesalers. Currently, the Austrian supplier of ing is to provide a complete solution in the direction of a professional collector suppliers are making various efforts to put forward a complete package of heating program (including heat pumps and boilers), rather than is to provide solar water heater

Global solar water heater market scan Netherlands Switzerland
[REVIEW] In 2006, the Dutch government abolished subsidies contribute to the solar market fell sharply in 2007 the market will grow significantly, the growth rate of 33%. Swiss solar market in the past two years, showing a more prosperity.
Netherlands
In 2006, the Dutch government abolished subsidies contribute to the solar market fell sharply, while in 2007 the market will grow significantly, the growth rate of 33%. Although the Netherlands, sales of solar products is still small, but growing public awareness of solar energy products and systems improvement, and the Government of the people on global warming and environmental issues to guide understanding of the market in the past few years show an upward trend upward.
As the economic downturn in 2008, the Dutch solar market in 2009 compared with 2008 growth of 28%. From September 1, 2008 start, energy and innovation organizations in the Netherlands Ministry of Economic Affairs, the implementation of a new subsidy policy, the building has been used to promote the use of renewable energy. The New Deal to make up for the decline in new construction solar energy market, and to have a pulse throughout the solar market growth. In 2008, the Netherlands installed collector area of ??more than 25,000 square meters, of which 90% were flat. Dutch manufacturer of vacuum tube collectors, the poor impression that their performance is poor. Therefore, in the Netherlands only a few vacuum system provider, such as Rivusol BV, Heliomax BV and Helios Energie Systemen BV.
First quarter of 2009, negative economic growth in the Netherlands 4.5%, since the end of World War II, there is the largest decline. Thus, in 2009, local residents are very cautious consumer spending, sales of solar collectors less than 3 million square meters.
From the sales point of view, the market did not change much in 2008 and 2009 sales were 6.2 million and 710 million euros. Despite the recent choice of materials used to absorb more solar energy, but the copper is still the major Dutch companies throughout Europe and even the use of absorbent material. Good thermal conductivity, hardness, and other technical characteristics of copper favored by the manufacturer. However, some manufacturers have recently started using aluminum heat sinks.
Aluminum heat sinks only have a market share of 2.5%, still in its early stages, but market share is expected in the next few years there will be some growth. This is because the price of aluminum is cheaper, partly because of its light weight.
In the Netherlands the market, vacuum tube collectors are new products, so the market is more difficult to expand. Only a few manufacturers offer the product, most of which are manufactured in Asia. Most of these products formed by the ladder-shaped brass. For technical reasons, the majority of such tubes by the Chinese manufacturers. The performance of vacuum tube collectors have been verified, and Chinese products are certified before entering the market, but users still believe that this product is not good and the price is high stability, so the Dutch suppliers rarely offer such products .
In 2008, the Dutch solar energy products and systems primarily used in the existing residential buildings. This is because the decrease in new construction, on the other hand started in September 2008, the subsidy program to encourage installation of solar energy systems in existing buildings. As investors more cautious, so in 2008 the Dutch solar products and systems used in commercial buildings in the proportion of small and not significant in 2009, the growth.
Energy prices on the rise and make solar energy more to reduce the potential of technology in the future will be widely used in residential and commercial heating and cooling in buildings. Although the Dutch government to implement more stringent building energy regulations, but to reduce building energy consumption still more effort. At the same time, solar energy systems need to improve their quality to meet market growth.
Switzerland
Swiss solar market in the past two years, showing a more prosperity. 2007 and 2008, two kinds of vacuum tube collectors Peace plate sales rose sharply, the growth rates of 49% and 42%.
In 2008, the Swiss vacuum tube collector was the biggest increase, from 2007 to 3400 square meters in 2008 increased to 1.03 million square meters. In 2009, the market still maintain a growth trend, but an increase of less than 2008, the growth rate of about 35%. Flat-plate collector in 2008, an increase of 37%, while growth slowed in 2009, about 20%. Overall in 2009, the Swiss solar market growth of about 20%.
As the rapid growth of vacuum tube collectors, flat plate collector sales slightly decreased. However, flat plate collector in 2008 and 2009 still occupies 92% market share. Since the initial installation costs low, and compared and vacuum tube collectors, flat plate collector in the fight against snow, hail, and falling rock is not fragile, it is more popular.
2008 and 2009, copper is still the most common flat-plate collectors absorb the material. Aluminum holds 30% market share and is expected within the next two years will have a greater range of use.
In 2008, Switzerland has a large vacuum tube collectors market growth, sales increased by 3 times. Market growth are several factors: First, the vacuum energy-efficient products already requires a lot of hot water heating and hot water system operation is confirmed and approved, and the pressure from all sides makes people choose to use in new housing energy efficiency better heating system; Second, some product providers to develop simple and economical installation techniques, making the vacuum tube collectors and flat plate collector is more than competitive; Third, subsidies in many parts of Switzerland, to promote installation of vacuum tube collectors; Finally, many new manufacturers entering the market in 2008 to promote the development of the market.
Switzerland is currently the most popular vacuum tube collector is a U-tube. Heat pipe collector is very little use, because Switzerland attaches great importance to product quality and consumer.
New homes for solar market growth has played a very important role. According to statistics, in 2008, about one in four new families will have a residential solar system. In the past two years, multi-storey buildings to install solar energy systems increase in the number, and this trend will continue in the next few years.
Although in recent years the market has great growth, but in Switzerland, and other renewable energy technologies, solar is not very popular. This is mainly due to the initial installation of solar products and systems, high cost, and cost recovery time can be up to 20 years. In this case, the market growth is still mainly rely on government subsidies. However, the Swiss regional policy is different. In 2009, the government began to subsidize a unified national standard, less in those areas previously subsidy increase the amount of subsidies. Unified and effective in the ongoing subsidies drive the market going forward.
Currently, the Swiss local suppliers the lion s share of the market. Cheap imports and unpopular in this market, because the Swiss are focusing on product quality. Installers and manufacturers developing the relationship is conducive to market development of another way. Increase the number of imported products, increased competition in price and installation costs, help to reduce system cost, thus promoting the market forward.

When the subsidized products as home appliances, one of the new solar water heater on February 19 when the accident out of the official opening, through twists and turns, April 24, finally opening a successful solar energy to rural areas, nearly 140 solar energy companies participate in the bidding; May 14, the Ministry of Commerce, Ministry of Finance announced the list of winning companies solar energy to rural areas, 92 companies won the bid. According to experts, from participation in the bidding companies and successful business point of view, bidding companies lack the number of firms throughout the industry, 2%, less successful companies throughout the industry, 1% of the number of firms, that is, the whole industry more than 98% companies not involved in solar energy to rural areas to become bidders.
Once upon a time, since early April, the state issued the tender documents solar energy to rural areas, some people on the \"bold\" prediction \"solar market will face a\" shuffle \", the dealer faces\" love and marriage door \"channels faced with solar variation! However, I recently visited the Shandong , Jiangsu, Henan, Hebei, Liaoning, Yunnan and other places in the market learned that, like the power source of solar energy, solar sun the rain, in Section Tianquan solar energy, solar energy a good, modern solar energy, solar energy in the blue section, a pass solar, Lok Sang solar energy, gold sun solar energy, solar light, solar seasons Mu-song, dual-energy solar energy, solar abundance days, peony solar energy, solar sun Tongji brand dealers, steady performance of home appliances, brand loyalty is very high, 95% The dealer said above, not because solar energy to rural areas and for the brand.
Dezhou a major brand to a dealer complained that, as early as March this year, the company introduced a highly competitive low-cost special products, and now the price winning products higher than in special machines, not competitive in the market Since May 14 announced the successful national enterprise, the brand in the end a highly publicized \"× × solar energy, State successful home appliances brand, 13% of the state\\ s subsidy,\" but people do not seem to buy it. \"Going down the product prices higher than the previous special, my customers shop less refrain from the last two months.\" The dealers look of frustration. The industry accounted for 98% relative to the solar energy does not participate in the bidding companies, their dealers are thinking of pressure to be much smaller, they can according to the manufacturer\\ s flexible policy, free to grasp market, a brand of Dandong solar dealer says the company has given us a flexible policy, from outside the box constraints, I am the master of the market in June, I sold only wall-mounted solar on more than 20 units.
It is understood that the industry accounted for 98% of companies did not participate in the bidding, there are many well-known in the industry have a very dynamic and strong growth of the brand, the author visited 28 companies in the construction and due to busy industrial park did not attend the tender has two; skills, improve quality, build up strength for the coming year to fight a bid turnaround of more than 10.
Analysts believe that solar energy to rural areas did not participate in the tender will not necessarily have the business conditions of the countryside, these companies do a good job Lianhaoneigong quality service, you can still win in the marketplace; and in the subject of some companies if you do not grasp opportunities will be lost in a good situation on the market.
Li Ping, president appealed to the solar dealer friend, to keep a clear head, strong faith, we should take a keen eye and sense of smell to capture market information, must not blindly follow the trend!

Solar water heater distributor of divorce doors in 2009
In 2009, for the solar thermal industry, is intertwined with the crisis year of opportunity, still in the aftermath of the economic crisis, solar energy and solar energy-efficiency labeling countryside just started this year, is full of variables, as people expect, which is also were at a loss. In this new trend among the companies have no choice but to actively play their influence gradually from passive to active; dealer\\ s role is more complex, they are both free men, while the company\\ s \"bonded labor\", which dual identity so that they tend to be more conservative choice when. In 2009, the door or the door, or just high or low threshold, some people go forward, some people cross out. In 2009, very lively. Wait and see? Or continue? Give up, or stick?
Between the market and the manufacturers, active in a group of people, they Na Zhaoqian, from manufacturers and then resell the goods sold, they are being called the dealer. Providers, both individual traders, but also a business unit. Like a spider-like, they own the dot, networking, the tentacles into every corner of urban and rural areas. Upstream manufacturers of products through their network of ground floor to the stream downstream of the center because of their special position, both manufacturers of trouble, or the market boom attenuation, while rapidly touch their nerve endings, they are a shoulder of the two, need to withstand the pressure from two sides, in 2009, for solar dealers, is bound to be an eventful.
09-year itch
1 changes in the economic crisis lead to industry
The end of 2008, as \"Baotuan winter,\" the word of the rapid popularity of the global economic crisis as quickly as the flu spread, first to import and export companies continue to lower profit margins, then a large number of migrant workers in coastal cities to return home, dozens of million college students, the unemployed, the property market downturn, even the roadside selling barbecue chicken are shouting a lot a lot of diners eat the sheep less. Solar thermal industry is not immune, the most intuitive expression that uplift the rural market.
The first is the momentum of continuous appreciation of RMB exchange rate continued to rise, resulting in shrinking international market; Second, the weak real estate market consumption, to some extent inhibited the domestic urban markets, the promotion of solar energy projects. In these circumstances, making large and small companies invariably chose the more robust strategy, returned to the countryside. As if the iron rice bowl is a rural market, whether it is to establish bases or just worth mentioning guerrilla in the mountains, who do not want to lose a crisis of this opportunity.
History tells us that every change is accompanied by severe turbulence, severe turbulence and, after washing, is the establishment of a new order. China\\ s solar thermal optimization and upgrading of industrial structure to form a high-tech as a precursor to production for support, backed by comprehensive service to install new pattern of development.
Temporary crisis will put pressure on the solar thermal industry, will no doubt accelerate industry restructuring and the reshuffle, the healthy development of solar energy industry standards, and perhaps this will be upgrading the development of solar energy industry turning point.
World Energy Research Institute Executive Director Finance, China Financial Research Institute Shihong He said: the rapid development of new energy industry will likely take this chance to the sky in this crisis, and become the strongest economic pillar.
(2) solar energy to rural areas to strengthen the awareness of the legal representative of dealers
After many setbacks, solar energy to rural areas and finally settled. April 3, China Electronics Import and Export Corporation under the Ministry of Finance Economic Construction Department, General Affairs Department of Commerce commissioned the \"national home appliances products ( ) project\" for domestic open tender. Enterprises as bidders, must be legally registered.
Given the special nature of the solar thermal industry, enterprise products only a part of pre-production, directly affects product really easy to use is another important aspect – installation and after-sales service are vested in the hands of dealers. In Chinese companies, enterprises and corporate representatives Trader separation is relatively common phenomenon, as a dealer, an independent legal representative of the attitude to the marketing of the more rare. We all instinctively avoid risks, you also hide his hide, the end result is often a risk by consumers pay.
Legal representative of 100% means that he will take responsibility, distributors and business are two separate legal entities, they have common goals, but also their different economic interests. Dealer Trader, the company is still very weak sense of business, the most common problem is short-sighted, irresponsible, make a left. On the solar thermal industry, it must rely on the dealer. Wu during the fair, the company CEOs gathered to discuss solar energy to rural areas, Jiangsu Sun Yu Group Chairman Xu first proposed the \"dealer filing system.\" This is the dealer will sooner or later face the problem, the traditional home appliance industry after several years running, has successfully crossed the threshold of this channel. Solar thermal industry will also make transparent the identity of the dealer, the dealer business and realize the integration of the interests of the community should not only equal opportunity, but also share the risk.
Relative to the companies, dealers belonging to vulnerable groups; relative to consumers, dealers and are a strong group. Do not be afraid to take risks, big as a real person, not to avoid risk is to obtain success, and are from the cusp to get out of. While a person who did not play a risk, but naturally had no weight. In the family that, in the unit that, in the industry also do so. Assume more a point, can count on the right to speak.
The current qualification to the dealer, can not cope alone solar power to rural areas, but, as a dealer, if you have this vision, we must first have this consciousness.
3 identifies the start of solar energy efficiency rank or grade separation
Putting aside the use of solar thermal energy products in the end can be how much solar energy efficiency label once affixed to the product, equivalent to more than a selling point. Better than nothing, better than low intensity high, consumers will certainly be inclined to energy-efficient products. Many dealers are inevitable with this kind of concern, worry inefficient operation will weaken their brand competitiveness, directly affecting their own economic interests. Businessman materialistic, this negative factor if not reversed the long-term, single-mindedness is not difficult to guarantee the dealer to divorce and remarry. Water flows downwards with the flow, rank or grade separation of the product, the dealer will also will separate the rank or grade?
Between companies and distributors in the advantages and disadvantages of solar energy to rural areas and solar energy-efficiency labeling of the double force, will not occur a major reversal? Although there is only a hypothesis, however, these assumptions are very possible. Companies need their own products based on the energy efficiency rating, the concerns of the right medicine for the dealers, and enhance the confidence of dealers.
4 second-tier brand to a survival of the fittest dealers focus
Survival is the dynamic of the show, death is mostly gone quiet, energy efficiency labeling system can be regarded as an industry reshuffle in the process of a chapter, to a certain extent, can promote the formation of a number of brands, especially the formation of a strong brand . Strong high-end brand will be more to the development of low-end brands out automatically directly, while the end of the brand will be the future of solar thermal market is the most compelling contenders.
Jiang Su Huayang Solar Co., Ltd. Huang Yongwei said: \"The concentration of the brand, I think through the model home appliance business, to reproduce in the solar industry, and that is how to seize the quality, to seize the product, to improve the level of concentration which can be accounted for in the brand is also a place. \"
09 The Door
Since the 1972 \"Watergate\" incident was leaked, the \"gate\" will become \"threshold\" part. Many people in the \"door\" does not step past the mouth, was tripped, stumbled. For example, Clinton\\ s \"zipper\", such as Huang\\ s \"explanation door\", such as Serie A\\ s \"call gate\", such as Edison\\ s \"Pornographic\" … … In 2009, the distributor of solar thermal industry is facing unprecedented opportunities, but also faced with unprecedented challenges, and opportunities of the place, it means change, a change of place, it means rebirth or death. 2009 Distributor of the \"love and marriage door\", how to cross?
Enhance team confidence
Store in a hundred passengers. This is an old saying. High and low energy efficiency rating and market share there is no absolute relationship, for ordinary people, his is the best fit. From high-cost energy-efficient, high cost and the price will naturally low levels of energy efficiency of different products and different price points will also have their own consumer groups. China 1.6 billion people, high energy efficiency products and then put the whole of China can not eat rice, so, also do not need pessimism low energy efficiency, as long as their products can effectively target specific consumer groups, energy efficiency is also a good market low .
Stable cash flow
General Manager, Le Sang Jing Ping solar business success comes down to the \"four military regulations,\" one military regulations, \"cash is king principles.\"
The stability of cash flow is simply the turnover of capital, not working, as if the flow of water can not, after all, is the backwater. Appropriate increase in liquidity, make an inventory of existing resources, the only way, when the opportunity comes, the dealer in order to grasp the opportunities; Only in this way, the crisis occurs, the dealer in order to resist risks.
Stable scale
Quantitative qualitative change. Dealers must maintain a \"quantity\" of stability, moderation in the pursuit of stability, based on the \"quantity\" of growth. Under the command of a soldier, soldiers the hands of a gun, the library has surplus, once the environment has changed, dealers can quickly be adjusted to deal with \"fortune overnight.\"
Strengthen the competitive advantage
Tian Ji\\ s horse should have heard the story, right? Emperor WEI of QI Qi general Tian Ji and race, Tian Ji\\ s horse into the upper, middle and lower third-class. The first game, Tian Ji and other horse on the finest horses to spend the middle horse of medium horse, horse of inferior inferior horse, and lost. Sun Bin was to give him the same idea: \"with your horse to deal with them under such fine horses, take your horse to deal with their upper middle horse, get your horse to deal with their middle-inferior horse.\" Finished three games After Tian Ji wins and one loss, the daughter of King of Qi won a bet. No one is perfect, the dealer can not cover everything, the dealer can not \"large\", but there must be \"a tip\", the first that the dealer\\ s core competitiveness.
Establish strategic alliances
Lack of dealers in the case of existing resources, leveraging an occasion to know. First, upstream to their own – by the supply side, the second is to own the same generation – by peers, third, to their downstream – by consumers. Many solar energy on a secondary market dealer of their own limited resources, the ability to open up the market varies. Said peer is the enemy, I believe that lovers can become relatives by marriage, as long as common interests. To give full force to play a strategic alliance, both sides must not only define their own right in the bull market is more important is that both sides must be clear in their respective obligations in a bear market, to really establish a strong community of interest, shared interests, the risk with Tam.

The development of to low-carbon future marketing
[REVIEW] sustainable is an eternal topic, as long as there are human beings, as long as companies, will never become obsolete and outdated. Society should be sustainable, do you want sustainable, but also to sustainable business, sustainable development is the key to solar energy companies and the criterion is the key to low-carbon market.
Recently, the well-known marketing plan Mu peak of a \"marketing of the four solar low-carbon direction,\" popular in the industry concerned.
In fact, since the weather in Copenhagen will change after the \"low carbon\" seems to be all-pervasive fashion, by various industries is to take something and put it marvelous. As the focus on new energy development and utilization of solar energy industry in China, although the development but 10 years, should be the most qualified to use the term low-carbon, but has remained silent. As a senior marketing planner, Mu peak points to industry and social point of view, with great foresight that the marketing of the four solar low-carbon direction, it simply is, first, the business development of high-view, the interests of safeguarding the industry, not strife; Second, technology products to continuous innovation, attention to mining customer needs; Third, the range of solar PV enterprises are facing market expansion, refinement of specialization is the trend; Fourth, the emphasis on brand communication effects, highlighting the public effort to enhance the brand reputation.
Solar industry leading planning agency – the prophet marketing plan that is undeniable, which now number four directions for the development of solar energy companies have a positive reference and reference value. In fact, careful study, the four directions can be used to replace a word, that is \"sustainable.\"
Solar industry to conduct low-carbon market, the industry is undoubtedly the low-carbon low-carbon behavior. Although the solar energy industry prospects are promising good momentum of development by leaps and bounds, however, and development can not avoid mixed Nishajuxia, so, in the \"situation is excellent\" in the case, entrepreneurs should quiet reflection. Because the objective laws of market economy are applicable to any one industry, survival of the fittest, survival of the fittest, to any new energy development for the solar industry has been no exception.
Focus on customer needs innovation, product life sustainable.
Product is close contact with customers business elements, the influence of brand products in the customer who is produced by refraction. The life depends on products and services, product life depends on the product\\ s value, no doubt, product value is determined by the needs of customers. For example, we all know, is the production of hot water for household washing, bathing, the same hot water, solar energy because the application of Lotte tourmaline technology, so that hot water is no longer ordinary, made in order to decompose the non-macromolecular Healthy water, which has become popular Lotte solar mystery of where the market. In other words, business and product life are holding in the hands of the customer. Customer demand with the times, age, change in taste changes, the success of solar energy products must seize the changing needs of customers and some may even be able to seize and discovering the potential customer needs, leading the trend in consumer spending.
The courage to assume social responsibility, sustainable brand communication.
There was a rich merchant said, when the accumulation of personal wealth to some extent, it is no longer personal, but social. Companies, especially, to a certain size, their social and play it on social responsibility has become more evident. A really good brands recognized by society, its content is not only good products, good service, more importantly, a sense of responsibility and influence. Foreign brands Microsoft, BMW, Samsung, Siemens is the case, the domestic public, Gree, Haier, sun rain is also true, whenever a community is a major event, we missed the presence of these brands, such as disaster relief, such as the southern flood . If we say that this behavior can be considered public means of brand communication, then, than the direct broadcast media advertising to more meaningful, but also more popular. Which, although not directly to the products and services, but the company will demonstrate social responsibility in the minds of consumers and their brand integration, reliability and loyalty will rise with it. Therefore, solar energy companies regardless of size, in the future development, social responsibility and concern for public welfare is a trend, just as the solar industry, Lotte rookie but a medium-scale enterprises, but in Yushu earthquake of modest means to make a business, and actively money and materials donations, to win social acclaim. The reason it is.
Safeguard the interests of industry, enterprise development and sustainable.
There is usually the first business enterprises to promote more development of the industry, the industry greatly increased influence with the company, in turn, will promote the development of auxiliary enterprises. So, business and industry, a prosperity, a loss for both sides.
Range according to the economic calculation, the solar industry is still only a small, but if the meaning from the get on a low-carbon, which is the largest industry. The early development of big industry, but also need the market to develop. Solar energy companies should be clear, real competitors are not peers, but those coal-fired electricity industry, so all the solar energy business sector interests should be, pushing the same line, to inform the public benefits of solar energy to the backward method of attack power consumption from them wins the market. Instead of \"cats and dogs.\"
Such as the Emperor Ming, Sun Yu, Qinghua Sun, etc., are able to clearly recognize this, issued a challenge to the traditional way of life energy, as industry leaders responsibility. As a small solar energy businesses, conform to the ideas and trends, will encourage enterprises to develop faster. Such as Lotte solar energy, put the mission from the early days of business located in the \"protection of the environment, caring for the earth\", the company completely separate from traditional energy companies, and with many solar companies to stand together and seek common development, growth industry, the development of their own.
Sustainability should be an eternal topic, as long as there are human beings, as long as companies, will never become obsolete and outdated. Society should be sustainable, do you want sustainable, but also to sustainable business, sustainable development is the key to solar energy companies and the criterion is the key to low-carbon market.

More than 6,000 solar water heaters compete or meet death batch
[REVIEW] June 5, Hubei Laohekou Hankou Road, identified as a \"flying sun\" brand solar water heater stands in the street a small upstairs floor, midday sunlight on it, came a little bit of gold, eye-catching.
June 5, Hubei Laohekou Hankou Road, identified as a \"flying sun\" brand solar water heater stands in the street a small upstairs floor, midday sunlight on it, came a little bit of gold, striking .
However, all this only proves that \"flying sun\" ever existed.
\"We have not done a water heater, quit the industry.\" Fei Yang Hubei original solar technology company sales manager Chen Yang told reporters, because competition is too intense solar water heater industry, the company was forced to declare the establishment of less than two years out of the market.
Old River is a relatively remote northwestern Hubei county-level city, population of just over 500,000. \"But on such a small place, there are at least seventy-eight engaged in solar energy plant.\" Chen Yang said that due to the influx of business too, we are unprofitable.
And this is just a microcosm of the solar industry frenzy. Data shows that currently there were up to more than 6,000 solar water heater business, of which nearly 80% are SMEs, and even a large part of the family-owned business.
As \"tailor-made shoes,\" as do the water heater
Two years ago, when Chen Yang determined to enter the solar water heater industry, he seems to see the blossoming future. With the global traditional energy supply has become tighter, new energy is not only sought after by many companies, but also by state and governments at all levels attach great importance to the solar industry in particular, which has become widely accepted.
In 2009, the state will include solar water heaters, home appliances catalog, which greatly promoted the development of this industry. This year, 92 countries in the original 79 new successful enterprises, a total of 171. And some provinces are also positive action, pushing the solar industry.
Precisely because of this, solar water heaters in the rural markets of the growth spurt, the industry is booming. Meanwhile, the city and other rural areas without restrictions, installation of a more casual, there was no floor is too high water pressure and inadequate technical aspects. Chen Yang can see the advantage when the time, more people in the industry have seen. Inadequate industry standards, and low barriers to entry factors make more and more companies flooded, scraping the limited market share.
The working principle of solar water heater is relatively simple, the use of solar thermal collector tube into, and through the heat insulating layer of water can be. According to one anonymous industry insiders, a set of tens of thousands of dollars of equipment plus five people, we can produce solar water heaters, but the quality is talked about how bad. Industry\\ s low threshold for many companies there are no obstacles to entering this field, part of the workshop-type enterprises as it is able to \"tailor-made shoes,\" as-made solar water heaters.
Solar Energy Technology Co., Ltd. Hubei Huan Xiang Wang Huan sales manager told reporters that the company was established in October 2009, but the harsh competition in the market, numerous difficulties, the product is not known, there is no price advantage, it is difficult to obtain consumer recognition.
Reporters in Hubei Laohekou a \"tailor-made solar production base\" to see, less than 40 square meters of workshop filled with all kinds of solar water heaters, semi-finished products, two simple production equipment was hung in the middle of the room. Outside, several brands of paste prepared to sell the finished product. The business owners told reporters that they can customized according to customer\\ s different needs of solar water heaters.
Reporters noted that neither the solar water heater production date, no manufacturer name, but no certificate of quality, with only a name to distinguish it from other brands. I understand that this is just a way to meet customer needs is based on the number of solar water heater collector tubes to determine the price. A tube 180, the price will be high to buy, buy less price is low.
When a reporter asked to have quality assurance, the owner of confidence that the quality is absolutely no problem, \"do not win the Emperor Ming not money.\"
Industry standard is to make this industry was mixed too low, companies of varying quality. China\\ s solar water heater industry is not implemented in production license system, and without going through the compulsory 3C certification. In the case of imperfect standard, many companies do not produce qualified were removed from them.
2007 drafted by some industry experts, \"China\\ s solar thermal industry standard Texas proposal\" has been signed; April 2010 by the Haier and other domestic and foreign suppliers, together with China Household Electrical Appliances Association, China Quality Association, the Consumers Association and other co-founded China\\ s first \"solar Quality Alliance.\" The solar industry in maintaining the normal order of a certain positive, but the industry generally believe that in the absence before the introduction of new national standards, industry status quo to change.
Solar water heater industry standards are GB/T19141-2003 \" system technical conditions\", GB/T18708-2002 \"domestic thermal performance test method\", while the national standard is too low, such as the national standard only provides a water heater\\ s pressure ability, did not make provision for corrosion resistance, and the welds are particularly vulnerable to corrosion leaks; the other hand, lack of industry standards, such as the national standard for outdoor piping did not make the relevant provisions, and winter management Road were frozen situation have occurred.
Low threshold and lack of industry standards resulting in solar water heater industry into a disorderly competition, some companies tend to use low prices of raw materials for production, and then sold at low prices.
The role of the superposition of multiple factors, the growth of solar amazing the number of firms, to Jiaxing, Zhejiang, for example, the region only in the first quarter of 2009 new solar thermal more than 300 enterprises, collector tube production line in the original 325, based on the expansion produced nearly 100. The solar water heater production to the national rate of 30% annual growth. Huang Ming Solar Energy Co., only a company\\ s annual promotion of collector area on the mounting area equivalent to the sum of the entire European Union, North America twice.
Price war intensified a crisis of survival
More than 170 businesses and thousands of successful countryside non-successful companies, coupled with Trade and Industry Bureau registration number has not been a small workshop enterprise, limited scraping is resorted to every means of solar water heater market, the declining trend in overall industry performance has gradually taken shape.
Sell ??high price, low price of the non-profit – this is one of many small and medium enterprises are generally solar water heater problems. A large part of the business model still in the market based on selling, no brand, no channels, lack of personnel and financial resources. In order to obtain respite, enterprises have to continue to fight the price, in order to reduce production from the deposit.
\"Low-end products are not sold well in the past.\" Zhejiang Jiaxing Solar Energy Industries Association a staff member surnamed Fan told reporters, because the influx of too much business and industry disorderly competition, and many other reasons, Jiaxing City, generally to reduce the solar energy business production, reduce production capacity, etc. deal with increasingly fierce market competition. He also confirmed to reporters to say the large-scale price war, saying a large number of small and medium enterprises or workshops to obtain a price war can only rely on the chance of survival.
According to industry analysts, due to recent rapid increase in solar water heater business, substantial growth in production capacity, but the corresponding market is not expanding. At the same time, by the Northwest such as drought and rainy weather in the south of the impact of consumer demand for solar water heaters are subject to certain degree of inhibition. Many enterprises struggle a bowl, will grab the wall.
\"The market is too small, but too much competition.\" Chen Yang told reporters in front of the raging tide of competition, in addition to cut-off than no better alternative. But also Wang Huan efforts, this time he had to use the weekend to keep contact agents, in order to get distorted.
According to relevant data, currently almost 80% of solar water heaters are varying degrees of declining sales, inventories and other issues, many of them as Hubei Fei Yang was forced to stop production of solar technology companies such enterprises.
In the high homogeneity of solar water heaters, there are no outstanding advantages, not only selected the core technology companies to reduce production costs to respond to repeated price wars. This will not only further exacerbated the extent of the cruelty of competition, there is also the part of the solar water heater leaking, no water, a lot of pressure and poor quality. According to reporter understood the complaints about the high rate of solar water heaters, and even consumers to reflect, water heater bought only one day on the water leaked inside a.
Guangzhou Institute of Energy researcher Dr. Xu Gang told reporters: \"cut-off because the company\\ s technical content is too low, they can do all you can do, the market is a bit confusing. Product quality is not, will not work in all aspects , slowly out of the market, the loss of customers. \"
Solar water heaters use a single large
China\\ s solar thermal technology research began in the 1970s, when research and development of solar water heaters, solar cookers and other related products began in the rural market. The 1980s, solar water heaters are included in the national \"Plan\" and the \"Plan\" scientific and technological projects. In the 1990s, our own design and matching collector tube production line, marking China\\ s solar water heater technology to mature. However, until today, China\\ s solar water heater industry is still the main focus in the development of this area.
In fact, the use of solar energy water heater is much more than one area. At present our country in solar lights, , solar stoves as well as applications such as solar building there is a certain development. But the embarrassing reality is that in the eyes of many people, solar energy equivalent to solar water heaters.
China has been the use of solar energy water heater only one. According to the Solar Energy Industries Association\\ s statistics, as early as 2007, China\\ s solar water heater production accounted for more than 7 percent of world production, production and use of solar water heaters to become superpower. However, the overall use of solar energy on our performance is not satisfactory. Although China has the world\\ s largest solar photovoltaic products manufacturing base, but the installed capacity of PV power generation system production capacity of less than 2%. Solar power generation there is a large gap between the more developed countries. Electricity costs are high, the lack of core technologies have affected the development of the industry. The solar building, solar street lamps, and other fields, has been because of technical and cost reasons, not been able to achieve industrialization.
As a result, many companies can only spotlight the threshold is low, a simple water heater technology, in this \"look beautiful\" in the industry to further expand production capacity, staking their claims, and ultimately thousands of companies trapped in this small space difficult to break.
\"In fact, small business shutdown of the entire solar energy industry is a good thing.\" Dr. Xu Gang that these low-tech, poor product quality solar products to be eliminated on the sound development of the whole industry is positive. For the future direction of development of solar energy companies, industry experts generally believe that the expansion of product areas, while branding is a priority. \"Solar water heater companies in order to win in the fierce competition, the only brand created from the start.\" Ebb Tide like shuffling through, not the core competitiveness of enterprises must be out, left behind is in the brand, technology, channels and so has a specific advantage of the enterprise.
Laohekou Solar Technology Co., Ltd. Australia match column Ba Jin also believe that only have their own brand, in order to enable enterprises to take a favorable position in the market.
However, more than 6,000 enterprises, more than 6,000 brands to create easier said than done? Their is not much time left, now it seems the entire solar industry still can not afford to escape this fate: in the water heater of this \"dead end\" in the melee continued, and then wait for the death of business volume.
