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.

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. \"

Flat panel will enter rapid development period

Beijing Solar Energy Research Institute, Assistant General Manager Liu Jun has said that this year will mark the second half of the domestic industry, the rapid development of flat panel solar period. Mainly reflected on the many manufacturers of the new production line or the introduction of flat panel products, and product R & D, fast forward, such as in coating technology, glass technology, thermal technology, production technology, product applications, building integration, etc., will carry out a number of technology development.

This year, the flat panel solar water heater works in the city market has shown explosive growth, increasing 50% year on year over the country, some of the industry key enterprises such as five-star solar panel is 100% increase, to achieve the double; many original primary production companies have launched flat-panel production line. Industry experts believe that 2011 is undoubtedly China\\ s solar thermal industry \"flat years.\"

In countries actively advocate and promote low-carbon economy and energy savings of the macro context, in recent years, have introduced the solar energy products around the \"put a order.\" According to incomplete statistics, there are already dozens of provinces and cities clear that new buildings must have . Last year, China\\ s building energy efficiency industry output has been close to 30 billion yuan in 2012, is expected to reach 66.4 billion yuan of the scale. According to the Ministry of Housing and Urban deployment, begun last year to promote building energy efficiency, that \"green building evaluation to identify an entry point, accelerate the improvement of green evaluation standards, improve the evaluation mechanism, evaluation of the implementation of the green flag system.\" In this context, more widely used in building flat-plate solar water heater is of great significance.

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.\"

with different regions

China has a vast, different regions of the s use a different installation requirements.

First, Jiangsu and Zhejiang

Jiangsu and Zhejiang area residents have the habit of bathing every day, require 24-hour hot water supply, and demand is larger. These areas generally rainy, to use hot water, first choose a large-capacity water heaters, water heaters, the use of high-quality insulation, with the first day of the rest of the hot water will need to maintain a few rainy days; the second is to increase the auxiliary heat source or Accessibility of solar water heaters electricity, less use of electricity in the circumstances, it can easily achieve all-weather hot water supply.

Second, the high-latitude region in Northeast

Northeast weather is cold, you can use a single vacuum tube water ratio lower products, such as choice of 2 m long vacuum tube 1, and a smaller water tank (inner diameter smaller) water heater, now there is a close-packed s are also suitable, use antifreeze-type 50-degree angle to the best solar water heater. Liaoning and southern Jilin must be on the water pipeline and water tank insulation layer on the use of thicker insulation material. Heilongjiang alpine region must multiply the area of ??household lighting, the upper and lower water pipe must be vented to prevent cracking pipes. Also, you can take heat cold (heating cable) measures, keeping in mind the temperature limit to prevent burn pipeline.

Third, Qinghai, Tibet, Xinjiang, Northwest

Northwest sunshine for a long time, intensity, and the temperature difference between day and night, conventional energy is not well-off, is the development and utilization of solar energy gold regions. There are experts from the sun, \"recent\" Qinghai-Tibet Plateau, the average annual sunshine radiation reached a total of 6000 ~ 8000 MJ per square meter, the annual period of up to 3400 hours of sunshine. Especially the western region of Tibet, solar radiation after the Sahara Desert, ranking second in the world. Although these areas, winter cold, but very good day sunshine, hot water temperature remains high, to meet people\\ s hot water needs. However, due to the larger sand, water heaters, wind resistance must be very strong.

Fourth, the Ningxia region

Ningxia region is temperate continental semi-arid climate, cold winter and hot in summer temperatures greater temperature difference. Long hours of sunshine, high strength, very rich solar energy resources. Although living standards are not high, but because of the unique geographical conditions, the solar water heaters are increasingly welcomed by the local people. Also located in the northwest gateway to the region, the solar business flow more developed, but to the local consumption of solar water heaters.

Five areas of Fujian and Guangdong

Low-latitude region of Fujian and Guangdong, is a subtropical region. Hot weather, water heater pipe insulation need not cost the same price you can buy a larger lighting area and tank capacity of solar water heaters. Although the alternating rainy but frequently confront, does not affect performance, high-capacity solar water heater provide enough hot water every day. But the best use of auxiliary heat source to meet the longer rainy weather.

Sixth, Yunnan and Guizhou

Most parts of Yunnan, a subtropical monsoon climate, with its spring season of solar water heaters available to good effect, and without cost to the water heater pipe insulation. This high penetration of solar water heaters, air pure, full of sunshine, has a unique geographical and climatic conditions and the environmental awareness of people with higher energy. Water heater is mainly flat, because the price is relatively low. Vacuum tube solar water heaters also have a certain market (price lower than the flat tube for now, read this sentence deleted). Guizhou is located in the plateau, the terrain and climate, and vertical changes significantly, cloudy, fog more, the use of solar water heaters must be auxiliary heat source (electricity, gas) in order to achieve all-weather hot water supply. Due to climate topography and other reasons, Guizhou, solar water heaters use less common.

to prevent the six errors

The right to buy at the same time, the correct use of the concept is also very important and should be avoided \"six errors.\"

    Reporters recently learned from the Consumers Association of Guizhou Province, the last few days Provincial Industry and Commerce Provincial Quality Supervision Bureau of solar water heaters on the market thoroughly checked and found that both the behavior of the manufacturers or businesses are not standardized. To this end, the Provincial Consumers Association issued a consumer warning: the purchase of solar water heaters to grasp the \"four key\" to prevent \"six errors.\"

According to reports, the purchase of solar water heaters, concentrating to see the effect, should be used to buy as much as possible interference film world\\ s leading patented technology of the three high vacuum tube; second look at the insulation properties, select the incubator, we must focus to see insulation layer thickness, insulation materials and processes; three to see the bearing strength, should try to select \"Apply streamlined tower bearing\"; four watch brands and services, should try to choose the strength of the manufacturers of brand-name products.

The right to buy solar water heater at the same time, the correct use of the concept is also very important and should be avoided \"six errors.\" First, only need it a bath of hot water in winter, in fact, bath water temperature should be higher than body temperature can make the skin pores open and clean the skin effect will be good; Second, buy a water heater is only used to take a bath. In fact, not only can take a bath of hot water, but can be used to vegetables, washing dishes, etc.; three, with hot water than cold water to spend more money. From cleaning and sterilization of view, double the hot water arrived over five times in cold water, but is saving water; four, are heated with hot water to, to wait. Use of solar water heater to ensure hot water at any time at any time, without having to wait; five, can not use solar energy in winter, difficult to use, with a small amount of winter electric auxiliary heating, electric or gas water heater than the direct heating water to save a lot of electricity; six Solar buy the bigger the better. Reasonable choice is the resident population by household water capacity.

urgent introduction of national standards

Recently, the introduction of solar thermal state of the five new measures, including: amendments to the \"Renewable Energy Law\"; preparation of the national new energy promotion plan, the development of solar thermal as a focus; city of each province, three demonstration projects, demonstration projects 4 counties to expand the solar energy to rural areas. Solar energy through the \"late spring\", \"quality gate\", but also is ushering in a development opportunity, this time more need for a mandatory national standards for solar water heater industry to regulate the industry. And this standard when issued, let us wait and see.

    Solar water heater industry is known as \"grass-roots star\", born from 1978 to now has more than 30 years. During 2004, China vacuum tube solar products out of the window-start on the world stage fling. By 2010, there are already more than 150 countries were using Chinese-made solar water heater products, solar energy companies involved in export business, has reached more than 230. However, in the country in recent years, the solar industry in the praise and criticism in the highly controversial, especially CCTV one earlier this year exposure OEM solar water heater solar water heater industry, the program will once again push the wave of public opinion. Industry with low barriers to entry, product quality is uneven, there are a number of \"artisanal\" small business is typical of the solar water heater industry.

Although solar water heater several leading enterprises sun, rain, Emperor Ming the healthy development of the brand, product and technology in record highs, in the rural areas into the city on the road has also made good results, but more small and medium enterprises, workshops factory technology and products will still remain in the shoddy level, resulting in a \"solar heat is not one to winter\" phenomenon.

Industry in the chaos of the time, the majority view will be one of the reasons point to the chaos of the industry standard.

China currently has 23 national standards for solar water heaters, and why the industry is still a pack of \"chaos\"? \"Flat solar technology\", \" thermal performance test method\", \"Solar water heaters heat-absorbing body, connecting pipe and fittings used in the evaluation of elastic material way\" and other national standards for solar water heaters, but easy to see that these standards are not a whole national standards for solar water heaters, and no after-sales service, installation and other aspects. In addition, all public sales of solar water heaters do not need a separate test, as long as the enterprises in accordance with national standards to produce, own commitment to protect the quality of products can be marketed.

Currently more about solar water heater standard, a variety of recommended standards. Take Shandong Province, before the launch of the solar industry consortium standards, that is, Shandong Province, Shandong Association for Standardization and co-sponsored by the Solar Energy Industries Association solar Union standards in Shandong Province as a provincial-level industry standard, Shandong, more than 400 solar energy companies that they meet the Alliance machine standards, Shandong Province by the Solar Energy Industries Association for the record, that can be used in the corresponding product on Union Flag. This is the recommended standard in Western Shandong solar industry norms, but also can not help with some limitations. While business-to-the \"higher than the national standard,\" the Union standards expressed different views, different needs of urban and rural market prices, different functions of the product, the market needs for rural low-priced products, demanding a high standard recommended standard, can play much? \"As long as manufacturers do not cut corners, shoddy, different brands of solar water heater only feature much, the price gap between them, can fit the needs of different markets.\" Says a company has.

This is more than 20 recommended standards for business only \"reference value\", companies can refer to, is not enforceable. No enforcement of standards, we can say \"no binding constraint gentleman villain\", a large-scale enterprises have become a mature product and market, in product quality and installation is guaranteed, but the small factory workshops in order to save costs retail prices are low and gain market advantage, and not to implement the recommended standards, it can be said for sales at the expense of quality. Therefore, no mandatory national standards throughout the industry, to a certain extent, resulting in uneven solar water heater products industry, industry cohabitation status.

Lack of supervision, industry believes that the chaos is one of the reasons. Solar thermal use of the Committee, rural development and utilization of new energy committee, the Consumer Electronics Association, a Beijing, Wuhan, two solar quality inspection centers and other institutions, in addition to a variety of industry alliances, alliances such as the local industry, associations and so on. And so many \"will\", \"center\" \"alliance\" exists, it seems difficult to say whether the agency is to manage the specialized agencies of the solar industry.

Recently, the solar industry is about to introduce a national compulsory standards.

By the National Development and Reform Commission, China National Institute of Standardization, the National Standardization Technical Committee of solar led the drafting of the first mandatory national standard – \"home efficiency of limited value and energy efficiency rating\" (hereinafter referred to as \"energy efficiency rating\") has into real operational phase, sent to the national energy efficiency labeling management center validation, and is expected to launch in the second half of 2011. As the standard for energy efficiency standards will be revised to mandatory standards, it is also known as the industry\\ s first solar water heaters mandatory standards. Solar water heater solar water heater energy efficiency standards will be divided into three levels according to energy efficiency, an energy-efficient, three minimum energy efficiency, companies can not meet three criteria will be eliminated.

But unfortunately, the revised energy efficiency standards are a part of the national standard, a part of energy efficiency, the other part is still not mandatory.

Recently, the introduction of solar thermal state of the five new measures, including: amendments to the \"Renewable Energy Law\"; preparation of the national new energy promotion plan, the development of solar thermal as a focus; city of each province, three demonstration projects, demonstration projects 4 counties to expand the solar energy to rural areas. Solar energy through the \"late spring\", \"quality gate\", but also is ushering in a development opportunity, this time more need for a mandatory national standards for solar water heater industry to regulate the industry. And this standard when issued, let us wait and see.
