Flat panel solar water heater policy to turn over power call the shots

Currently, a vacuum tube solar and the solar panel on the market share battle, is quietly brewing in the industry. Vacuum tube solar panel and solar energy, solar collectors, as the current two basic forms, the shift in the contradiction between the two determines the competition.

    At the time of the last century, a variety of vacuum tube solar objective conditions of rapid environmental and developed, the various types of vacuum tube technology also will be leaps and bounds, and eventually occupy the Chinese solar thermal market share of 90% or more, and has been the main consumer in thirty-four grade end of the market.

    In recent years, with the national policy on the mandatory installation of solar water heaters, and the introduction of a number of subsidies, the solar market sales over a relatively larger proportion of urban and rural areas with both hands as the inevitable direction of business sales. As a bear market rally of the urban market, the construction and installation of solar energy require a higher degree of aesthetics, which gives the solar panel provides a good opportunity.

    Professional Committee of China solar energy, said Luo Zhentao, villa and flat water heater especially for large-scale projects to use, many provinces and cities nationwide now house and large-scale public construction projects are ready to choose to use flat solar water heater. This became the city to seize the advantage of solar panel.

    Sheng, general manager of Mei Jianzhong that solar energy, solar panel not only the urban market. Focus on the current city projects installed, most or vacuum tube solar energy. Now choose some beautiful buildings in search of the solar panel split, but because of the tall buildings, floor space is not enough, there is often shortage of light, sunshine four hours, unable to meet the demand for solar energy use. Once the focus turned to the roof installation, then the price better vacuum tube collectors Party has become the first choice.

Tortuous path of into the city

Water heater in the past, China\\ s urban market has been dominated by gas water heaters, electric water heater gradually occupy the town in recent years, mainstream, solar water heaters have begun to enter the urban market, they represent the future direction of development.

As we all know, solar water heaters with gas water heater, electric water heaters in parallel with one of the three water heaters. Water heater in the past, China\\ s urban market has been dominated by gas water heaters, electric water heater gradually occupy the town in recent years, mainstream, solar water heaters have begun to enter the urban market, they represent the future direction of development. But in the town on market competitiveness, solar water heaters with gas water heaters and electric water heater, there are still some gaps. The reason is mainly because the \"alternative\" is not strong enough, leading to solar water heaters have become tortuous road into the city, met numerous tests, it can probably be attributed to four points:

First, the product quality \"alternative\" is not strong enough

Cold in the winter, the solar water heater exposed to the atmosphere is very susceptible to freeze plugging pipes, leaks, or even burst, part of the consumer complaints are not solar water heater tank insulation, vacuum tube solar collector efficiency is poor, easily broken, and life is not long. However, gas and electric water heater tank in the room, there\\ s security issues and the use of losses have been effectively addressed.

Second, the product design \"alternative\" is not strong enough

In the city, whether hanging flat or rigid is difficult to integrate into the urban design of a wide variety of architectural styles of buildings, in appearance will have a certain disharmony. The design problem is not there for personal consumption, but also in the market to promote solar water heater project to become a large obstacle. However, gas and electric water heaters and small footprint design aesthetic respected by most of the urban consumers.

Third, the product brand \"alternative\" is not strong enough

Some well-known brands of solar water heaters in the eyes of the industry visibility is good, but it is unknown among urban consumers, many people do not know enough of the solar water heater, think it is immature technology, the use of no confidence. In fact, this is not strange ignorance of consumers, a new role as a market, branding is not in place, even the well-known brand has become the industry\\ s enterprises, but also without a stable core competencies, severely squeezing small businesses malignant. For this problem, many companies are in accordance with the new energy market through international sourcing center of the world\\ s solar power to expand brand awareness, after a shortcut.

Fourth, after-sales service \"alternative\" is not strong enough

Service delay constraints of solar water heater has become a major bottleneck in development of the industry. At present the production of in most of its strength as bad, not a huge sales team, they take a price war to capture the market, a bold claim to be \"high efficiency\" and \"lifetime warranty\" that the majority of the false promises to lure consumer confidence. The gas and electric water heaters in the maintenance and problems are relatively easy to find on some consumers to be able to solve.

\"Alternative\" is not strong enough lead to strong consumer demand and market competitiveness is not enough to make the product does not have enough marketing ability. Solar water heaters like \"city\", if you do not change the current situation in which companies do not attach importance to the above four points, the result is likely to withdraw from the town is depressed huge market.

All-glass features

    A vacuum tube introduced

    (1) vacuum structure: all-glass vacuum tube solar collector is the core component is the engine of the entire solar system, its performance determines the merits of the whole system was thermal performance and longevity.

Schematic diagram of the all-glass vacuum tube

    All-glass vacuum tube one end of the opening, the inner tube and outer tube of the nozzle to melt sealing ring; the other side were closed into hemispherical head, inside the glass tube with a spring support bracket on the outside glass to buffer thermal expansion shrinkage caused by stress. Including glass and laminated between the outer glass tube into a high vacuum pumping. The end of the outer tube to protect the general bonding a metal cap to protect the vacuum after the closure of the exhaust nozzle. The appearance of glass topcoat selective absorbing coating. Spring bracket is equipped with a cool down agent, it is used in evapotranspiration after the vacuum tube to absorb the gas generated at run time, to keep the tube from the vacuum effect.

    (2) Tube Material requirements: 3.3 borosilicate glass vacuum tube used (iron oxide content of below 5%; thermal stability; low coefficient of thermal expansion, as 3.3 × 10-6 / ?; thermal shock resistance, heat resistance temperature is greater than 200 ?; have high mechanical strength; good resistance to chemical corrosion; has good optical properties, transmittance ≥ 0.89).

    (3) vacuum tube technology requirements:

    ? material is borosilicate glass, 3.3;

    ? air drying performance parameters y ≥ 175m2 ? / kW (when the solar irradiance G ≥ 800W / m2, the ambient temperature t at between 8 ~ 30 ?)

    ? nausea drying temperature increased to 35 ? required amount of solar radiation exposure ≤ 3.8MJ / m2 (when the solar irradiance G ≥ 800W / m2, the ambient temperature t at between 8 ? ~ 30 ?)

    ? average heat loss coefficient ≤ 0.9W / m2 · ?

    ? vacuum ≤ 5 × 10-2Pa;

    ? should be able to withstand the thermal shock of cold water below 25 ? and 90 ? above the impact of hot water alternately repeated 3 times without damage;

    ? pressure should be able to withstand the impact of the pressure of 0.6MPa;

    ? hail requirements should be not more than 25mm in the radial size of the hail damage is not under attack.

    (4) vacuum tube specifications.

    Second, the vacuum

    Solar water heaters is the use of the greenhouse theory, the solar energy into heat energy, in order to achieve the purpose of heating the entire package of water, usually by the solar collectors, storage tanks, brackets, a combination of controllers and other accessories, if necessary, to increase aid heat source.

    (1) how it works:

    Solar hot water heater is a light converter, different from the traditional use of nature, such as drying, lighting. Vacuum tube solar water heater is the core of his elongated structure as a thermos bottle lamps, a vacuum between the inner and outer layers. On the surface, including glass coated with a special process using spectral selective absorbing coating, to maximize absorption of solar radiation. By sunlight, photon hits the coating, solar energy into heat energy, water absorbs heat from the outside coating, water temperature, density decreases, the upward movement of hot water, while the proportion of cold water down. Hot water is always located in the upper part of the tank. Also hot water heating solar water heater in case the temperature has little to do with the outside world, depending on the light. When you open a kitchen or bathroom faucet any time, the hot water heater will depend on the natural fall out, the greater the gap, the higher the water pressure.

    (2) solar water heater structure

    (3) solar hot water system plans

    Third, all-glass vacuum tube solar collector

    (1) all-glass vacuum tube solar collector operating principle

 

 

    (2) all-glass vacuum tube collectors, the basic structure

    Number of branch tubes are arranged according to certain rules of the union of vacuum tube arrays with the tube (or Header), tail bracket and reflectors and other components together to form a vacuum tube collectors.

    All-glass vacuum tube collectors are generally associated box round and square, the use of stainless steel production, collector piping joints welded at both ends in the United box. Side or both sides of the joint box according to the design of the vacuum space hole, directly into the open end of tube joint box, tube and between the United box sealed by silicon rubber seals.

    In order to improve the performance of vacuum tube collectors, some of the manufacturers of products in the back of the addition of vacuum tube array reflector, mostly flat diffuser, generally aluminum or painted flat white paint is made. Because the reflector long-term exposure to air, easy to accumulate dust and dirt, require frequent cleaning, or reflections will be affected, and the collector reflector increases drag and affect the stability of collector installed, so the sand relatively large areas should not be installed with a reflector plate collector.
  

All-glass vacuum tube solar collector structure diagram
   

    According to the different vacuum tube installation, all-glass vacuum tube collectors can be divided into vertical alignment (north-south) and horizontally (east-west) two order forms, of which there are arranged horizontally level of single-row and two kinds of double standards the form.

    (A) vertical arrangement of all-glass vacuum tube solar collector

    (A) levels arranged in all-glass vacuum tube collector (double)

    All-glass vacuum tube solar collector arrangement diagram
   

    (3) application

    As the vacuum tube collector has a simple structure, excellent performance, advanced production technology and reliable, especially for large-scale mass production characteristics, so since its inception, in just a few years it has been considerable development. However, due to pipe the water to go in the running if a damaged, the entire system will stop working; and a larger heat capacity of the vacuum tube, vacuum tube solar water should be heated to the output of hot water, and the evening, vacuum tube the hot water will not be fully utilized, resulting in a certain amount of heat loss. Vacuum tube collector can not be used in pressure systems, generally open only for centralized s. Products can not be used for the balcony wall.

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.

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.

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.
