Solar water heater industry in chaos
This year\\ s \"Mei Chaofeng\" thunder and no rain, continuous in a hot state to bring a trace of cool weather, but in China\\ s solar water heater industry, is also looking forward to a timely and cleaned up the industry in chaos.
Production of chaos
Since the quality of the door incident Haining, solar water heater industry in the production of more attention on the chaos. Successful home appliances products in Hubei Province, there are four quality solar water heater failure, on the State Administration of Quality Supervision, \"Heibang.\" Countries around the solar water heater for Quality Supervision and Inspection Center in Beijing, Hebei, Liaoning, Jiangsu, Zhejiang, Anhui, Shandong, Henan, Yunnan and other nine provinces, municipalities, 60 companies produced 60 kinds of system products were random detection, a total of eight solar water heater product failure, many of whom have a more well-known home appliances business.
Solar water heater is a low threshold for industry, small artisanal producers flooding, and these small factories in order to reduce costs in the production of the intermediate links are cut corners, streamline the necessary processes. As the saying goes, Clothes make the man, hidden in between the shell and liner insulation material is most likely to cut corners content. Some manufacturers in order to save costs, scrap foam padding directly to the inside, or use of insulation materials used, such as insulation effect can be imagined.
Sales of chaos
Solar water heater sales are weather, such as the summer is the off-season sales, some dealers will attack first, while sales of solar water heaters, on the other side is selling appliances or debris. Reporters visited many dealers stores, some stores display clutter, poor impression; some even open a solar water heater will be placed in the bracket and put a bunch of the bile duct, without the knowledge of consumers do not see this selling is the solar water heater.
In the sales cycle, solar water heaters will be worth double the sales from the factory to the original ex-factory price 400 yuan, into the hands of consumers may need more than a thousand. These differences are middlemen to take, but genuine products to consumers in the hands of only a few hundred dollars value, quality and service can not be guaranteed.
Sale of chaos
After-sales service is one of the solar industry, a crux. Consumers to buy solar water heater, when the dealer to buy a mouthful of good things can wait until a problem is left to push the right push, if they had to do their own thing. Such as Ms Tang Tsinghua purchased two light brand of solar water heaters, the total price of 7,000 yuan. Ms Tang and the dealer was agreed, the first payment of 5,000 yuan to pay the remaining costs after installation. Subsequently, the dealer sent to Ms Tang, home to install a solar water heater can be installed after a good but not out of hot water. See dealer sent to her home, after her house maintenance staff to repair water heaters do not, have the rest of 2000 dollars, and said that if the remaining money is not paid, they would not repair. Encountered such a service, how can consumers be assured to buy solar water heater?
Solar water heater industry chaos, which makes large purchases of businesses need to have the problems, how to purchase to quality assurance, service secure solar water heater? I know a number of sales distribution center, such as Mando international building materials market, decorate the city of Wenzhou, Tongxiang new international energy markets. I believe that the new international energy market Tongxiang solar water heaters as a distribution center to ensure quality, service, etc. to provide a reliable guarantee. Settled in the market for domestic famous enterprises of , the market for these companies to provide regular technical exchanges, exhibitions, training sessions, etc., in order to enhance the competitiveness of firms, with the upgrading of competitiveness, product quality, service, and will be improved.
Solar water heater industry chaos, not only the need for a unified industry guidelines to regulate the market, but also requires all manufacturers, distributors of self-discipline, not blind pursuit of economic interests to the detriment of the interests of consumers in the market at the end.

Save the solar water heater with standard quality crisis
\"It is because of the strict manufacturing and testing systems, the U.S. ranked six times larger solar spot the red list in the forefront of national supervision.
In 2011, China\\ s \"second five\" the first year. Market in 2010 experienced a baptism and integration, the majority of solar energy companies in the market is full of confidence. However, the recent frequent exposure of solar water heater product quality problems, indeed, some companies a headache.
frequently the product quality crisis
Recently, the China Central Television, \"Weekly Quality Report\" to \"sun shadow\" as the subject, full exposure of the poor quality of the production process of solar water heaters, as well as end-consumers in the process of problem – poor insulation performance, service life is short. The news that the poor quality of the manufacturers of these products have been carefully packaged, sold nationwide from Haining. And to remind consumers to purchase must keep their eyes open. The news immediately caused an uproar in the country, competing media have also reported that some consumers are skeptical of solar water heaters.
Not long ago, some media reports, Beijing, Hebei, Shanxi, Shanghai, Henan, Chongqing, Xiamen, Shenyang, Changchun, Harbin, Chengdu, Xi\\ an and other 24 provinces of CASE (Council, Consumer Protection Committee) and the Chinese consumer by the newspaper, jointly launched a solar water heater usage survey. Survey, there are currently 40.87% of the solar water heater in the winter on the \"strike.\" Even in winter you can still use the solar water heater, and only 35.9% of \"easy to use hot water and adequate\", while 29.4% will have \"often use electric heating\", 25.2% is only \"a warm, barely used,\" while 9.5% poor results because of the use \"is rarely used.\"
Solar energy enterprises should actively take the road of brand development
\"We have to be traced, through the phenomena of nature.\" Zhejiang Solar Energy Industry Association Xia Zhisheng said. Some dealers in order to short-term interests, operating near the brand-name products, misleading the consumer. But it also shows that the solar industry, the big brands have not formed enough influence to change the dealer to make money for the purpose of irresponsible thinking, while consumer guide, refuse to buy substandard products and Pong brand. From the root so as to put an end to the recurrence of a similar phenomenon. In addition, many solar companies Haining region has also been active in taking brand development, such as the United States large, high music, God, too, and everyone hot. As consumers, businesses must be responsible, first of all is the product quality should be excellent, or very long.
As China\\ s solar thermal industry leading brand, one of the top ten largest U.S. solar energy industry CO., LTD is located in Haining, Zhejiang. Large Group 30 years the United States attaches great importance to product quality, and won the trust of dealers and consumers. U.S. vice president Zhang Jiangping largest solar company, said that since its inception, the United States a large solar energy has been \"quality first, reputation first, customer first, service to the community,\" the business, quietly saving for our country contribute to the cause of environmental protection. Not as high profile as some of the spread of solar energy companies, solar energy is the United States has been practicing great strength, technological innovation, strict quality control to enhance the overall strength.
\"It is because of the strict manufacturing and testing systems, the U.S. ranked six times larger solar spot the red list in the forefront of national supervision.\" Zhu Xiaoliang, Minister of the United States largest market, said, \"It is worth mentioning that in 2007 the National Quality Supervision, Inspection and Quarantine Administration of the country in domestic s for supervision and checking of the results shows that the U.S. was useful for large solar water heater on high heat and then, once again set a record of CIQ, up 46.66% over the national standard 11.0MJ/m2, the average heat loss factor is only 54.55% better than the national standard. \"
Allow consumers to feel safe in the solar water heater
\"At present the industry that there are some discordant voices, more perfect in our industry standard, enterprises should strictly enforce the no problem.\" Xia Zhisheng president said. Hope Zhejiang , from the perspective of the consumer is responsible to eliminate the production of solar water heater products, and continuously improve product performance and service levels, promote rapid product upgrades, so that consumers feel safe in the solar water heater.
At present, China has become the world\\ s production and use of solar water heaters superpower. Governments at all levels and relevant departments are making great efforts to promote the popularity of solar water heaters, Beijing, Hainan, Jiangsu and the introduction of policies specifically for users of solar water heaters use the appropriate subsidies, the purpose is to promote solar water heater industry healthy development of this sunrise industry . In this context, some seek short-term benefits as a result of the illegal manufacturers, the production of solar water heater quality problem, affecting not only the popularity and promotion of solar water heaters, solar water heater will also affect the healthy development of this sunrise industry.

2011 industry upstream straight
Recently, in order to truly understand the solar water heater industry market conditions, the reporter visited the solar water heater and equipment manufacturers gathered in Jiaxing, Zhejiang.
In early 2011, Haining solar energy \"quality gate\" makes clear this is an extraordinary start. Since then, the ensuing cost pressures, severe weather, the decline in purchase demand is not proven in a test of the solar water heater industry. Recently, in order to truly understand the solar water heater industry market conditions, the reporter visited the solar water heater and equipment manufacturers gathered in Jiaxing, Zhejiang.
Absence of personnel costs
\"Money shortage\", \"power shortage\", \"labor shortage\" This is a business reporter at the hearing to reflect the most visited in the issue, but also the plight of China\\ s manufacturing industry in general.
A vacuum tube manufacturing company in charge told reporters that the vacuum tube in the production process requires a lot of power consumption, the electricity a month into the current business close to one million, while logistics costs are also rising, has hampered their sales volume.
The rise in labor costs has become an indisputable fact. This year, the frequent shortage of workers in the Pearl River Delta region, the manufacturing sector experiencing the same concentration of the test of Jiaxing. In the visit, told reporters enterprises generally reflect the rate of increase in labor costs this year, more than 15%.
\" are also labor-intensive industries.\" A manufacturer of solar bracket official said: \"So far, the front-line production workers wages have been floating for 17 percent of production caused a lot of pressure.\"
\"Front-line workers, bad move, and technical talent is a hard to find!\" Wanbao solar energy to the reporter complained. In recent years, transformation and upgrading of solar water heaters have become the urgent needs of the enterprise, and the possession of very few high-end technical talent, talent has become the introduction of short boards, which restricts the pace of corporate restructuring and upgrading.
At the same time, the data show, this year, the solar water heater to maintain the price of raw materials market is still rising trend. Silicon, rough tube, stainless steel, sheet metal, polyurethane varying degrees of price increases, which rough tube and foam material per tonne increase has reached 45% and 38%.
The face of raw materials, rising labor costs double the pressure, many companies profit margins are compressed sigh. Meanwhile, some companies are seeking to change in the situation.
Transfer of production bases has become an option to avoid the high cost. Home Depot Solar General Manager Xu Ye-ping said: \"At present, the central and western regions of the labor costs and electricity, site of the investment are relatively cheap, Home Depot has been in Sichuan Guangyuan invest vacuum plant, expected in mid-September can be the ignition of production . \"
Steady pace for a breakthrough
Although there are many problems, in 2011, solar water heater industry still maintained a steady growth trend.
And demand slowdown in the domestic market compared to the international solar energy market there is greater profit margins. Data show that in 2010 total production of solar water heater Haining 3.5 million units, production value of about $ 3.8 billion total annual exports of about $ 20.1 million, an increase of about 480%.
God, too, told reporters about the solar charge said: \"God is too time solar access export markets earlier this year, the RMB appreciation, the international financial situation deteriorated, and other unfavorable factors, the growth rate has decreased, but the solar market is still overseas corporate profit growth. \"
Chery solar charge also told reporters: \"Chery solar concentrating on the domestic market in the past, in recent years, companies will also look into the overseas, at present, enterprises in the overseas market, sales are steadily rising.\"
In addition to expanding markets, broaden the product line has become the focus of many corporate strategic transformation.
\"Currently, our R & D focus on heat pump water heater.\" Wanbao solar charge to the reporter: \"In the future, we will achieve heat pump water heaters and solar water heater combination, relying on the Wanbao Group\\ s financial advantage, to open the export project.\"
Also focus on the engineering market, Le Sang solar energy will \"treasure\" in a flat charge on solar. Sang Le Solar official said: \"Sang Le is the vacuum tube solar panel solar energy to transition through the Architectural Design and build a platform for real estate developers, construction market in recent years has achieved substantial growth.\"
Yang Chen Yang Hong, general manager of Hong Kong Solar said: \"The development of solar energy products should function.\" July 2010, Yang Hong Kong developed a \"solar living water\" was included in the 2010 National Spark Program, \"Solar living water\" was pulling the sun in Hong Kong product marketing. This year, the sun can be directly introduced in Hong Kong to provide drinking water solar water heater, want to pull through this again new terminal sales.
Jiaxing solar energy transformation and upgrading of enterprises has become the general consensus, which, Jiaxing Zhu Ling Xu, Secretary General of the solar water heater, said: \"At present, solar water heater industry is in the inflection point, the industry should be provided from the production of hot water to heat, from low-end climb to the high-end products are diversified, diversify, building integration, the solar industry over the next decade will be the focus of development. \"

In general, the mountain is prone to lightning hazards, plains and cities, lightning appears less. However, not long ago, the city north of a residential building on the plot being struck by lightning. "If lightning protection measures in place, city building also liable to lightning." Bureau of Meteorology lightning experts said, nearly four years, statistics show that most lightning in August Hefei, now is the high incidence of lightning, the need to guard against.
Poor communities struck by lightning lightning
It is understood that the area being struck by lightning, close to the reservoir, the surrounding open space, Hefei day of severe convective weather in some areas, there is thunder and lightning occur, according to the point discharge principle, lightning struck the roof of the cell shape angle, causing the roof shape corner missing.
Community residential buildings struck by lightning after the incident, Bureau of Meteorology experts dedicated to its investigation. In the survey of experts found that the roof of the air terminals and lightning network and deflectors did not weld, causing lightning current discharge does not go out, resulting shock wave effect, so that damage to buildings. "Even the design, the objective is to create beautiful roofs many of treasure spire-like, around the more open, is the tallest building in the ground, so the lightning from the objective to become the target, due to the top of the lightning rod and the building is not material deflectors and grading ring connection, so being struck by lightning. "participate in the investigation of lightning experts said.
Not be affected much by mine safety regulations
Phenomenon similar to the plot is more common in Hefei? In this regard, the city Bureau of Meteorology s lightning experts said, the residential district in Hefei similar phenomenon rarely, but there are still some security risks, such as the delivery of some high-rise buildings or other owners of after use, the owners will be in the building without permission top and top side of the installation of solar energy, water tanks, network security and other equipment, however, after the installation of these devices, there is no basis for the building phase connected to ground deflectors, lightning can easily lead to accidents.
"According to the" Lightning in design ", in the high-rise buildings have two or more piles as ground-based drop, to have air terminals, lightning network, to be set up electrical SPD (surge protector), 60 meters above the grading ring to have doors and windows grounding, while all have a certain resistance grounding resistance range. "experts say, as long as the lightning protection of buildings in accordance with regulations, the public can not worry about lightning safety.
Hefei August is the high incidence of lightning
According to the 2006 to 2010 weather data in Hefei, Hefei Bureau of Meteorology experts Hefei lightning lightning occurs, a special study of the law. From lightning occurred in the past four years, statistical data, the experts found, Hefei, April to September each year lightning-prone, which appeared in August, the highest probability of lightning. When the variation from the lightning flash to see, day 16 to 20 pm and hair, of which up to 18 when lightning occurs.
"From this result, we can conclude that: lightning in August, is the critical period, if there is lightning activity, the people around 18:00 to go out as little as possible." Bureau of Meteorology experts lightning, thunder and lightning occur, people should stay indoors and shut doors and windows, people who work outdoors should shelter in buildings; should not be used without lightning protection lightning protection measures are inadequate measures or the TV, stereo and other electrical appliances, not to use tap; Do not touch the antenna, pipe, wire, metal doors and windows, building facades, away from the live wire and other metal equipment or other similar devices; reduce the use of telephone and mobile phone.

The introduction of solar water heaters mandatory standard will usher in the industry or shuffle
Solar water heater industry\\ s first mandatory national standard – \"home energy efficiency of limited value and energy efficiency rating\" standard (hereinafter referred to as \"energy efficiency rating\") will be officially released, \"is currently in the public notice stage\", the National Standardization Technical Committee of solar Secretary-General Jia Tieying told reporters, and then came with the standard matching \"domestic solar water heating system energy efficiency labeling rules\" also \"the fastest will be the official end of the publicity,\" and ultimately by the NDRC, AQSIQ issued .
Solar water heater industry\\ s first mandatory national standard – \"home solar water heating system energy efficiency of limited value and energy efficiency rating\" standard (hereinafter referred to as \"energy efficiency rating\") will be officially released, \"is currently in the public notice stage\", the National Standardization Technical Committee of solar Secretary-General Jia Tieying told reporters, and then came with the standard matching \"domestic solar water heating system energy efficiency labeling rules\" also \"the fastest will be the official end of the publicity,\" and ultimately by the NDRC, AQSIQ issued .
China\\ s solar water heater industry is expected to have changed spared from the current situation. Industry standard introduced soon
Currently how many s? No official uniform data to answer this question. China Rural Energy Industry Association Solar thermal Professional Committee Luo Zhentao told reporters, \"there are at least about 3,000, which includes the middle and downstream industry chain, and manufacturing of solar water heater company at least 2000.\" Jia Tieying is that \"the country there are at least 3,000 to 4,000 companies of varying sizes of solar water heater business.\"
In 2010, the relevant department for industry to develop national standards. Luo Zhentao with many experts in the field and solar energy companies are involved.
It is understood that \"energy efficiency rating\" indicator has three levels, a product that energy-efficient. The mandatory standard \"requires certification through the WTO, but with Chinese characteristics, mandatory standards with international standards is not the same, mainly because the water heater industry development status is not the same.\" \"Standard for the industry to the introduction of is a major event, \"Jia Tieying said.
Why is the \"Solar Water Heater\" standard first enacted? Jia Tieying that \"all domestic water heaters, solar water heater market accounts for more than 70%, now is a one solar water heaters are used, especially in the second and third tier cities and rural areas, standards relating to specific household livelihood, a large engineering systems standards there, the industry prioritized the development of a process. \" Small workshops will now close down
In Jia Tieying view, the introduction of standards for solar water heater industry, \"a shuffling process,\" \"not up to standard, in this process will certainly be eliminated.\"
Domestic solar water heater brands, \"buy equipment, rent a shed is a company, the brand can not go on, and then change the name, still one to two million a year to earn. The industry needs to avoid non-standard work.\" Honeywell Honeywell (China) Co., Ltd. China Ministry of Environmental Controls Division Sales Director Zhang says.
Zhang Ke believes that \"a solar water heater industry will experience the process of upgrading, the process is coming, and then air-conditioning industry is down, the refrigerator industry development path to take, those industries out of the giant.\"
Zhang Ke that \"energy efficiency rating\" for the introduction of standards is a good solar water heater industry, \"Let their own initiative on quality and brand of solar water heaters, main market in rural areas, and regional characteristics are obvious, other than Barry well-known brand and the brand within three years, consumers will choose? \"Zhang Ke said,\" It\\ s like the cosmetics industry in rural areas, as more consumer brand awareness for relatively weak. \"
Beijing Solatube sun energy [1.06 0.95%], founder of Wang Zhi Technology Co., Ltd. will be told the \"Daily Economic News\" reporter, solar water heater is a low threshold for industry, small artisanal producers spread, \"especially in the area around Beijing and Zhejiang Haining , the birth of new businesses every day, every day the old companies have disappeared. There are many products for rural solar water heater only sell 800 dollars, the quality of these products are bound to have such problems. produce chaos, chaos sale , after-sale chaos is the basic status of the industry. \"
After the standard Wang Zhi would think that the main development of the rural market for solar water heater is a small workshop fatal blow, \"especially in the area around Beijing and Haining small workshop.\"
Insiders also told reporters that \"a mandatory standard may not be able to save the industry had a solar water heater industry, there are too many formats, the new standards can play what role, is not that good.\"

International policies to protect the healthy operation of
Chinese solar water heater business to be more and better international, macro government level should be \"shot.\" Rely on the rigid laws of the market regulation and government constraints simultaneously, to protect China\\ s solar water heater industry, international health run.
At present, there are at least about 3,000 solar energy producers, and companies manufacturing solar water heaters at least 2000.
Today, solar water heater industry\\ s first mandatory national standard \" system efficiency of limited value and energy efficiency rating\" standard will be officially released with a matching \"domestic energy efficiency labeling rules\" also \"will be the fastest at the end of the official publicity. \"
With worldwide energy shortage situation deteriorating, the world in an unprecedented adjustment of the development of solar, wind and other renewable energy resources, the introduction of a wide range of policy measures to encourage and promote renewable energy industry to accelerate development . Although China is the world\\ s largest solar water heater state ownership, but ownership per capita in Israel are still far behind other countries, the Chinese market has become an international market is an integral and important part.
Maturity from the consumer point of view, Europe remains the largest consumer of solar water heaters, but the United States, Canada, Mexico, represented by the North American market, with South Africa as the representative of the African market, to Turkey, Syria and other Middle Eastern countries represented in the Middle East market is booming.
Application systems from the product point of view, to Europe, Australia and other developed regions, represented as the product of its own awareness of solar water heaters are more mature and use, coupled with its own characteristics and construction spending habits, mostly confined system products, and as the Middle East, South Africa, India and other regions of China, demand for products closer to market conditions, mainly in non-pressure systems.
The competitiveness of the product itself from the point of view, vacuum products in some mature markets, because of its flat products in the winter compared to the superior performance, and is positioned as a high-end products, but in some countries and regions, the vacuum tube products clearly been \"ill-treatment \"for flat products of the\" second-rate substitute \", of course, and some of our small company spirit of\" making a point also earn \"business philosophy and shoddy product-related.
European flat plate collector is still dominated the market, or a tube supplement products, but part of the market has shown its own advantages and with the performance of the price advantage in China.
As the world\\ s different countries and regions of the solar water heater for consumers with different consumption habits, but also because different parts of the water quality, water supply in different ways, different structures, different national standards and customs of different cultures, etc., forming the world\\ s countries many solar water heater products personalized needs. If you can meet the demand of these differences, we must have strong technical support and the ability of independent innovation.
Chinese solar water heater business to be more and better international, macro government level should be \"shot.\" Rely on the rigid laws of the market regulation and government constraints simultaneously, to protect China\\ s solar water heater industry, international health run. Government should introduce policies to support the promotion of the internationalization of China\\ s solar water heater industry, the rapid development. Many countries in the world of consumer products in the use of solar water heaters have subsidies, such as the maximum subsidy of 60% in Germany, the UK system, subsidies for each ? 500, the Austrian government subsidies for solar water heating systems for each home € 2,000 and so on. At present, China is no preferential use of solar thermal. The state should develop renewable energy from the perspective, to take appropriate measures to encourage and support solar water heater business to carry out technical R & D and product upgrading, increasing production and consumption of enthusiasm. Economic integration in the global market environment, the government should first protect the domestic solar energy solar energy enterprises and foreign enterprises in the same starting line, there is a fair and equitable environment for development, not in terms of competition one step short.
