services, long road upgrading

In recent years, and by the policy of home appliances in rural market demand – driven blowout, double the size of the market, a number of capital and the interests of rent-seeking to market speculators. \"

    Recently, the solar water heater Haining exposure for CCTV companies there are a lot \"near the famous,\" \"shoddy\" and other acts, will the number of solar water heater company said in an interview, \"Haining event just opened a domestic solar water heater manufacturing chaos Council tip of the iceberg in recent years, and by the policy of home appliances in rural market demand – driven blowout, double the size of the domestic solar water heater market, a number of capital and the interests of rent-seeking to market speculators. \"

    Chaos in the market: industrial transformation and the resistance encountered

    \"Well into the door, Qian Haozhuan, risk, return quickly\" become frequent chaos solar water heater incentives. In addition, market supervision in place, the complete chain of product standards also provide a survival benefit speculators. In recent years, the sun, rain, seasons Mu-song, Emperor Ming, Sang Le, Haier and a number of industry leader, driven by strong competition in the industry is moving in the pattern of scale, branding the whole industry chain of direction, but still a large number of solar water heater manual workshop, speculative interest groups are located in Zhejiang, Beijing, Henan, Jiangsu, Anhui, Yunnan, Shandong and other regions, the rural market on the \"spoiler.\"

    Jiaxing Solar Energy Association, the Secretary-General Xu Zhu Ling told reporters, \"the chaos in solar water heater Haining there is not a day or two the end of 2009 there are a lot of leather workshop, weaving workshop saw this piece of market opportunities, have to intervene. Low cost, low-price competition in the market, while access to a certain development, but this model is facing a greater business risk. \"

    Although there are many problems Haining solar energy, but the reporter in December last year released the latest issue of \"solar water heater successful home appliances business announcement,\" see, there were only 19 companies Haining successful region, far higher than other cities.

    Beijing New Energy and Renewable Energy Association, vice chairman of the Lessons is that \"the past two years by the good momentum of the solar market and large prospects, the development of many enterprises are more impulsive, aggressive fact, technological innovation in solar energy products, sales service, product quality, there is still much work to do. \"

    Services, short legs: long road upgrading

    It is reported that there Haining CCTV exposure \"Hong Kong Haier\", \"Hong Kong Sun Rain\" and also appeared in large numbers near the famous acts in other provinces and cities, not isolated cases. Four Seasons Mu-song, the sun Po, Wong Ming, Tongji sun, Haier, Sang Le, and other famous companies directly suffered a \"fake\" shock. According to Jiangsu Solar solar Dajia Ban Bao responsible person said, \"some hands on workshop is often what is sold on the market what is produced, fake treasure not only affects the reputation of the sun, but also disturb the market competition order.\" To this end, the business in the company established within the Dajia Ban, run around all day in the first-line maintenance market brand and market interests.

    Counterfeit products, near the famous acts such as it is behind the endless worrying solar product quality. It is understood that the current domestic solar water heaters rely on the main service dealer located in the township is responsible for, and not as traditional appliances as professional services firms, and even sell products for many companies do not provide services to the dealer responsible for the full commission.

    \"Sales and Service Combo can quickly promote solar energy to rural areas, but the pattern is easy to replace the distributor for enterprise service issues arising once a company withdraw from the market, or replacement of a dealer market, then the previous sales products and services can not be guaranteed. \"A solar energy company pointed out that at this stage many enterprises do not have enough money and effort to establish after-sales service system, focus is still\" expand sales to grab market \".

Haining market need specification

    February 24, held in Beijing, \"the quality of analysis of special press conference\" on the Ming emperor, the sun rain solar water heater companies say the recent disclosure by the CCTV Zhejiang Haining \"Emperor Ming of Hong Kong\", \"Hong Kong Sun Rain \"and other problems of solar water heater products, rather there is no relationship.

China Renewable Energy Industries Association Professional Committee chairman Zhu Junsheng said, in the event of Haining, Zhejiang solar water heater industry sounded the alarm.

February 13, according to CCTV \"Weekly Quality Report\" report, Haining City, Zhejiang Province town, Huang Wanzhen and some family-owned factories, the use of the Ming emperor, the sun rain and other names, production and sale of \"Emperor Ming of Hong Kong\", \"Hong Kong Sun Rain\" and other solar water heater products. These products present no insulation, leaks and other quality problems.

Beijing Jianheng Certification Center, said Zong, vice president for Haining, produced by the \"Emperor Ming of Hong Kong\", \"Hong Kong Sun Rain\" solar water heater quality problem, for two main reasons. One is the cottage, the use of hand-blown way, can not meet the water tank insulation thickness requirements, resulting in poor water heater insulation; the second is the water tank metal thickness is not enough processing too simple, easily lead to leaks, reduce water heater life . In his view, these substandard products are still \"near the famous\" issue, to mislead the consumer.

For \"China solar water heater industry with low barriers to entry\" point of view, Zhu Junsheng said, China has 23 national standards for solar water heaters, industry, business is more developed standards. \"The problem is not that we do not have standards, nor is our standard level is too low, but we are the market supervision.\"

However, he said, \"Most of these 23 standards are voluntary standards, the next step will be to develop a mandatory energy efficiency standards.\"

According to \"Beijing Times\" reported that China\\ s solar water heater energy efficiency standards have been reported to the National Standardization Management Committee. Standard one of the drafters, China Rural Energy Industry Association Solar thermal Professional Committee Luo Zhentao introduction of the paper, the standard of energy efficiency by the solar water heater is divided into three, the highest level of energy efficiency, the lowest three energy-efficient, can not achieve the three standard enterprises will be eliminated. However, this standard has been questioned. Beijing New Energy and Renewable Energy Association, vice chairman of the Lessons of the \"China Enterprise News\" interview, said: \"Now, even how to calculate the area and uniform heating are not clear, how to count the value of energy efficiency? National standards emphasize the authority and science, to have time to explain the introduction of clear standards, that would be absurd to. \"

Zong believes that the incident solar water heater Haining essence of asymmetric information, consumers do not have the relevant expertise needed to identify third-party agencies to guide consumers to make the right choice. Because of this, where his Beijing Kam Certification Center has started the solar water heater industry, \"Golden Sun\" certification, more than 4,000 Chinese enterprises in the production of solar water heater, there are the Ming emperor, the sun rain solar water heater 30 through which business a certification.

According to Beijing Jianheng Certification Center Web site information, the center established by the China Institute of Metrology, is a non-profit organization. \"Golden Sun\" certification is derived from the National Development and Reform Commission, the United Nations Development Programme, Global Environment Fund, \"the establishment of China\\ s solar water heater certification system\" project supported by the Beijing Kam Certification Center created and implemented.

enamel spray prospects

Universal situation: At present, whether domestic or international market stainless steel liner is almost extinct; as control period by the popularity of stainless steel inner liner to enhance the period over enamel, stainless steel liner so the market share is still large. Some solar companies have tried to produce enamel interior, but the enamel interior, investment, output short-term benefit is not obvious, even to fail, many companies do not labor and return.

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.

\"Liner\" is the heart of , their characteristics affect the overall life of the product. According to the HC surface network Xiaobian understand, easy to implement as stainless steel liner technology, production equipment, R & D costs are lower, the vast majority of products on the market uses a stainless steel liner. However, the industry\\ s technology level restrictions, stainless steel liner susceptible to corrosion, easy to absorb deflated, pressure defects such as poor performance has been unable to solve. The enamel interior with durable pressure, anti-corrosion, anti-smoking flat, clean water and other features, has been popular in the field of electric water heaters, solar interior is also upgraded to provide a reference and reference.

A solar water heater to reveal the history of development

Tank anti-corrosion technology, for the water heater is a very important. Water heater tank is a history of anti-corrosion technology\\ s development. We went into the mall counter electric water heater, see the \"Titanium Liner,\" \"Kim Kyu-liner\", \"blue magic liner\", \"enamel interior,\" and so many inner names. In fact, the interior is basically the use of enamel process, just to reflect a selling point of differentiation, from the name of the manufacturers just not the same. So far, the water heater from the original galvanized steel liner, to the stainless steel liner, to the enamel interior has undergone a total of three generations of history.

Water heater through the course of development of three generations

? The first generation of liner: zinc, copper liner

Features: thin protective layer, no rust treatment, easy to scale, short life.

Universal situation: basically disappeared.

? second generation tank: stainless steel liner

Features: good material, not rusty, but the biggest risk is \"weld.\" There are two on the inner ring and a straight seam weld, the weld between the cross-junction, the junction of the stainless steel of the original ingredients were seriously damaged and susceptible to corrosion of chloride ions in tap water, bring to the water pollution.

Universal situation: At present, whether domestic or international market stainless steel liner is almost extinct; as solar heat control period by the popularity of stainless steel inner liner to enhance the period over enamel, stainless steel liner so the market share is still large.

? the third generation liner: enamel interior

Features: high-tech products, cylinder liner surface in thick enamel, metal or ceramic materials, mostly silicon compounds, together with seamless welding technology, can bear a greater range of temperature, usually -60 ~ +450 ? temperature range, to be able to withstand sudden changes in temperature. Physical characteristics, compressive, tensile, elastic, electrical insulation, non-polluting; chemical properties, acid, alkali, high temperature, water vapor, a variety of ions can not penetrate its surface are, can not effectively ensure the quality pollution.

Universal conditions: the rapid development of domestic and foreign markets, consumers and strong sense of identity, the most growth potential.

This shows that enamel interior, electric water heater in the birth of the field is a long process. From galvanized steel liner, to the stainless steel liner, which developed into enamel interior. At present, domestic and overseas markets, enamel interior, have switched to become a mainstream product. One course of development of the electric water heater longer, with a few decades or even centuries. At present, whether domestic or international market, stainless steel liner has virtually disappeared, enamel interior products universal. Stage of development of solar water heaters due to the restrictions, the vast majority of enterprises are using the stainless steel liner in the application of non-pressure solar water heater has some advantages, larger market share.

Enamel interior are high-tech products. Through the thick steel-plated enamel surface glaze, can bear a greater range of temperature, usually -60 ~ +450 ? temperature range, to be able to withstand sudden changes in temperature. Physical characteristics, compressive, tensile, elastic, electrical insulation, non-polluting; chemical properties, acid, alkali, high temperature, water vapor, a variety of ions can not penetrate its surface are, can not effectively ensure the quality pollution.

The past two years, the solar interior enamel rapid increase market share, especially in the split pressurized solar project market has shown outstanding performance, more and more manufacturers and real estate agency in importance as the product of choice for the project under pressure. The future development of solar water heater industry, market pressure will become the dominant application. As the industry growth restriction, the current popularity of stainless steel liner industry to phase and phase enamel interior needed to transition.

Fireworks debris smashed

    Recently, Ms. Qi, who lives in Jiangdong District, reflected the roof of her home glass tube was broken after the fireworks debris hit. A solar water heater maintenance man also told reporters that during the Spring Festival, he met only the glass tube water heater was smashed remnants of fireworks events, there is more than 40.

The public about: solar water heater collector tube rupture

Ms. Qi Ming, who lives in Park District, Jiangdong District, top floor of Building 2, Zhaohui Road, next to the residential buildings.

According to Ms. Qi, February 20, she opened for several days without solar water heater and found no hot water, also heard from the roof down the drain extension of \"shabu shabu\" dripping water. She suspected the solar water heater on the roof leaking, he gave the family all water valves are turned off, it was found that water still kept running.

The next day, she called the maintenance man, maintenance man climbed up the roof, the roof brought back a round from the hard soil group.

Ms. Qi told the maintenance man, the reason why her family\\ s solar water heater can not be used, because the glass tube is broken, it should be fireworks after the explosion hit down to earth group, because Ms. Qi placed in the floor around the water heater, distribution of many such soil group.

Reporters witnessed: There are many fireworks residual soil floor group

Ms. Qi told reporters at the Lantern Festival, a unit near her home in the discharge of fireworks, it is estimated the glass tube water heater that\\ s when crack hit by fireworks debris. She looked for the unit, put the other side recognize the fireworks, but do not think Ms. Qi is the home water heater damage caused by fireworks.

Yesterday morning, the reporter went to the house, Ms. Qi. In her home, saw maintenance workers take down the soil group were round, white and hard texture of reality. Reporters then climb on the roof that, Ms. Qi glass to the left of the first root of the central tube rupture, the bottom of the mottled rust water, and broken glass falls near the seam and the floor tile surface. In the water heater side of the floor surface, the reporter also saw many of the same group of white earth.

Maintenance man: Spring has treated over 40

To Ms. Qi Chen home solar water heater repair master told reporters, because Ms. Qi around the roof of the water heater, there are many groups of soil residues of fireworks, so he believes that the fireworks explosion tube should be the impact of residual soil group was ruptured.

Master Chen told reporters, during the Spring Festival this year, he has met more than 40 fireworks explosion heater tube is broken or smashed by the events of fireworks debris.

Ms. Qi reporter then visited the house fireworks within the meaning of the unit. This unit, said a staff member: Ms. Qi has looked for them, but the Lantern Festival day, many shops are near the discharge of fireworks, so it is very difficult to put their units in the fireworks debris smashed a home water heater set Ms. Qi heat pipe.

Ms. Qi said, although I do not know about who caused her family\\ s fireworks debris collector tube solar water heater burst, which makes her feel a bit sorry, but she hoped other members of the public through newspaper reminder: fireworks must be designated The open area in order to avoid unnecessary losses to others.

Weibo optical machine – no winter

    Recently, electrical marketing in 2011 at the annual meeting Wibaux, Wibaux company developed \"optical-One\" solar water heater for the display and promotion, which is Weibo appeared in the \"Guangdong Industry 500\", \"new energy heating water System Project, \"developed after the first generation product, is a\" no winter, the solar water heater, \"said Minister of Research and Development Department director the more of this product will be listed in June. The news caused great interest of agents across the country.

It is understood that \"one optical drive,\" the biggest advantage is to solve the traditional problem of solar energy in winter can not bath, and greatly broaden the conditions for the use of , making the top of the households of non-use can also be installed to solve the problem of high-rise buildings can not be installed.

Weibo developed the \"optical one machine\" on all fronts to solve the various problems of traditional solar:

First, the acquisition cost equal to or slightly lower. . Although the general use of traditional solar energy saving, but because of the winter water temperature is low, and inadequate sunlight causes the sun, bathing in winter usually takes to achieve the additional purchase of electric water heater, and the purchase of a 100 l water heater requires 1500 to 2000 yuan, taking The same bath effect, Weibo \"There is no winter solar water heater\" and the ordinary solar plus a 100 l water heater purchase cost equal to or slightly lower.

Second, the installation costs low. As Weibo one machine to achieve a water tank photovoltaic collector plates with separation, can be installed on the balcony, wall, window, roof, flexible placement, and reduce the water, greatly reducing installation costs, it can not be installed to solve the problem of high-level, making the non-top Users can also use, greatly expanded the use of solar energy conditions, more cities for the promotion of solar energy applications.

Third, the use of low cost. Weibo one machine due install photovoltaic water is short, completely avoid the use of a water heater installed in the attic at home, each of which takes up a lot of water in order to have hot water problems, to minimize water usage; the same time in the spring and autumn, in the solar meet the requirements bath, do not start the power to achieve solar bath, energy-saving, water saving.

Fourth, solve the traditional solar can not meet the bathing water requirements of winter ills. Traditional winter sun because sunlight solar, water temperature and low reasons, unable to complete the requirements of winter bathing, a \"three quarters\" water heater. The Wibaux optical one is configured with a national patent \"shaped cabin\" fast heating, solar absorber plate warm in the winter only as the role of water, the water temperatures warm to 20 degrees, and then shaped by rapid heating compartment device, which means that you can achieve the goal of the hot water, as there is no real winter, the solar water heater.

Fifth, the body of the impairment rate by three quarters. Installed on the top floor because the traditional solar energy, all the external forces such as wind damage, rain, snow, ice are likely to head to the body from damage to four; and Weibo \"photoelectric one machine\" can be installed in the balcony, you can avoid the three headed accidental injury, minimize the possibility of machine damage.

The future, Weibo provincial technology center will be a platform, in good split wall-mounted solar water heaters based on the gradual integration of the optical storage products are multi-functional integration, central water heating systems, direction, and further broaden the field of solar energy applications, to become a true leader in high-end energy-saving products.

Agents how to choose parts of

80% of sales of s rely on accessories to protect, the option is also very important.

    In the fierce market competition, how to create maximum profit for their development, as this is solar energy companies are seriously considering. At present, the rapid rise in the solar industry, there are about 4,000 large and small manufacturers, while the really big manufacturers also only a few dozen. Choose what kind of factory, agent what kind of brand, which is very important for solar dealers. Strength of large manufacturers, after-sale protection, but also hard to protect the dealer market development, development prospects, but the price is relatively high. However, this also depends on the local level of consumption, if the low level of local consumption, large selection of brand customer base is small, in order to have a big development is quite difficult, unless there is a large developer or government support. Large selection of manufacturers of brand is a good medium to do, after-sale protection, the face of middle-class consumers, a large customer base, development potential, could also face a more vast rural market, the development of space is very broad. Only choose the brand, to long-term development. 80% of sales of solar water heaters rely on accessories to protect, the option is also very important.

    How to choose solar energy meter?

    Solar instrument is the heart of the entire solar water heaters, solar water heater is running Command, solar water, heat, electric heating and other functions controlled by it. If the quality of the solar meter is not reliable, no end of trouble. The original bell solar instrument controller, display with highlights instead. After the 2002 launch of large-screen color LED digital display, full Chinese display running to fill the domestic solar industry in this field instrument blank, causing the solar industry, a major instrument of change.

    Solar instrument consists of three parts:

    One for the host controller can be divided into semi-automatic, automatic controllers and all intelligent controller. DC and AC automatic controller has two, simple, cheap, the main function: to set the water level, water temperature display, water water full alarm. Automatic control device by a solenoid valve sensor and the host component, the main features include semi-automatic controller, there are automatic Sheung Shui, Sheung Shui, water, regular Sheung Shui, Sheung Shui and low-pressure pipe insulation function, general instrumentation as well as anti running water feature. Whole host intelligent controller with sensors and solenoid valve components, including not only the above functions, as well as intelligent heating, heating time, smart water, regular water supply, power failure memory function, and some instruments have constant water temperature constant level of functionality. Quality of the mold with a host of times in the 30 micron thickness, no varistor, easy to lightning, the electrical wire inside the square is not easy to leakage resulting in serious consequences. Second instrument transformer temperature is too high, easy to burn and explode. Times the chip will lead to procedural confusion, poor immunity, prone to crash.

    Two of the probe can be classified according to the material of stainless steel probe and silicone probe. Stainless steel probe of stainless steel jacket heat shrink tubing and thermistor composition. The quality of a probe used it mainly to see the quality of heat-shrinkable tube. Solar water heaters in the annual 5 to 10 months, the water temperature in 80 ? ~ 100 ?, heat-shrinkable tube and plastic tube with the composition of rubber itself volatile, volatile at a high temperature plastic and stainless steel probe tube quality is the fundamental life Once glue or leaking pipes, damaged thermistor probe scrapped, instrument failure occurs. The best thermal resistance with an accuracy of one per cent, self-determined life of the material. Soft silicone sensor is divided into two kinds of silica gel and hard gel sensors. The external silicone sensor is composed of silica gel and activated carbon. The quality of the sensor silica gel and activated carbon depends on the viscosity and sex. The sensor is bad stick and easy to crack, resulting in the probe transmission signal denial or failure. General four-wire stainless steel probe, probe for the two silicone wire.

    Three instruments for the solenoid valve by the manufacturer on behalf of the general election, there are only back to the generation of filters, coils inside the standard as well.

    How to Select Solar tracer?

    The first tracer Raychem Corporation in the United States in the 1950s developed in 1984, China began to widely used in industry, 100 yuan per meter. In 1985, the Science and Technology Commission issued to the development of scientific research institutions file with the tropics, and set Spark Program. 1989 Siping use fluorine rubber research institutes and other polymer materials, the use of chemical technology, successfully developed the first hinge, and further improved, and the level of technology to stay ahead. Self-regulating heating cables are designated as National Torch Project, our research institutes and Siping said Lian Ping, with tropical sea. East China University of conductive plastics used technology developed using light radiation with tropical, but also tell you that the Wuhu tracer. Fluorine rubber stable performance, long life, high prices, conductive plastic to be cheaper.

    With tropical works: two parallel wires in the middle of filled polymer conductive plastic or rubber as with the core fluorine, fluorine rubber, plastic or polymer which is the skeleton of the matrix material and filler vectors Qi role of inorganic filler is the current carriers in the conductor insulation the formation of conductive network connectivity, from the current channel effect. When the power is turned on, the current through a wire through them with a wire core to another, and form a loop, with a fever after the core power and maintain the pipeline flow. This conductive plastic or fluorine rubber in the temperature rise, thermal expansion, so that part of the current channel network has gradually broken by the current is reduced, along with the reduced heat, when the temperature rises to a certain extent, the current and temperature are relatively stable . When the temperature decreases, with a core contraction, the current increased temperature, when the temperature rises a range Shiyou stabilized, which is self-limiting heating cables automatically adjust the temperature and the temperature of the principle. From the current market, with tropical allow the solar industry is not satisfied with the quality, we can only follow a large selection of manufacturers of solar products, after-sale guarantee. Super catheter stability, there is a certain Bureau of.

    How to choose solar water pipes?

    Connect with users of solar water channel, if a problem occurs, it will stealing or water filled camp, the consequences could be disastrous. Solar water used for the glue, the normal grip with three lit a look at two ways to verify. A look: pure color wall thickness; two grip: 30 cm with water several times 180 degrees of grip, grip at times on the white water, good water on the grip at the shiny; three lit: with 50 cm water in a circular motion on the gas stove burn center, when the water-like transparent burning, the hands turn a few laps the opposite direction, let go to recovery, his hands pulling the middle outside, round the more open the more homogeneous, the greater the sound off the better the quality.

U.S. installed Mibo my all-inclusive

Mibo water heater is actively promoting a \"buy water heater after the first renovation\" and \"U.S. equipment works\" new ideas, by the Changsha public concern.

    \"I\\ m home decoration, reserved water heater piping completely scrapped because of size issues, now only external piping, both ugly and costly.\" Recently, many consumers into the hotline reflects the house renovated in the water heater installation, worry about the emergence of these problems. How to solve these problems? I conducted a market survey to find a solution.

Survey

Water heater installation a lot of problems

Mr. Zhang Furong District, Changsha, spent $ 200,000 renovation to house the United States and the United States some surprise, only to find in the installation of solar water heaters, pipe fitting for the reserved size of the problem can not be connected, if the re-laying of the pipeline wall demolition the project is too vast, no alternative can only be re-Zhang external piping, seriously affect the appearance of home improvement.

According to my investigation, Mr. Zhang is the case many people have encountered. Most people will choose to present Changsha renovated the house, then consider the installation of water heaters. Since the space reserved for water heater installation and products not matching up to the requirements, resulting in some water heater pipe laying too long, making people wait time when using hot water too long, and even there only be removed for installation water heater half-wall, water heaters need to add lines and so on.

Solve

Leading ago that \"the United States installed Project\"

I understand that Mibo water heater is actively promoting a \"buy water heater after the first renovation\" and \"U.S. equipment works\" new ideas, by the Changsha public concern.

\"This concept as traditional Chinese medicine and philosophy, pay attention to the whole balanced, specifically, the consumer advocate selected before renovation of the house water heater, and then decorated with installation requirements.\" According to the water heater Mibo Zhao engineer, \"first After purchasing water heater fitting \"an innovative concept for the consumer to first solve design problems. Professional installers will house space and water heaters based on usage and other objective factors, through the systematic calculation and thinking, to develop a personalized water heater installation recommendations. In addition, the idea of ??making up the water heater installation is not complicated. The original concept with Mibo\\ s \"work-frame,\" so that the outlet, water pipes, circuits, and flue pipe installation and all other details, all the proper integration of planning, installing water heaters and space renovation to become seamless.

Commitment

\"US-installed\" My all-inclusive

How the house is decorated water heater installed? Mibo expert Yuan Jun remind consumers: with sales staff to discuss specific water heater installation program, you should pay attention to six priorities: water heater is easy to use, lines are too long, is reserved for accurate space, wires are safe and reasonable to reserve position in the hollow wall and whether it matches with the overall decor.

In order to better serve consumers, Mibo promised water heater purchase, after-sale maintenance, outlet, water pipes, circuits, and flue pipe installation and all other details of the overall effect of the decoration and the bathroom is with respect, are to provide consumers with one-stop all-inclusive service, on the basis of individual consumers can meet the installation requirements.

For many consumers worried about the water heater storage problem, Mibo said that in the terminal stores will have someone to keep water heater free of charge to the consumer until the consumer housing renovation work was completed after the on-site installation.

Guangdong popularity of solar water heaters start from now

Solar water heaters are very economical, with a family of three, for example, initial installation fee or three thousand dollars, but installed at least a day after saving eighty-nine degree, provincial electricity can be 1,000 yuan a year, in 2023 to recover costs.

Unprecedented cold weather, coal oil and gas emergency, coupled with the recent meeting in Copenhagen, brings to mind the energy-saving and environmentally friendly solar energy. Guangdong Province, abundant solar energy resources, but alone to promote the use of solar water heaters, the current strong rate of about 2%, well below the national average of 10%, inexhaustible energy wasted. Reporters interviewed the experts and the public access to both the proposal to develop a low carbon economy, the province can start from the popularity of solar water heaters.

Status ? ?

Utilization of solar water heaters in our province

Use of solar energy will significantly reduce carbon emissions and help our country to achieve emission reduction targets. According to statistics, the most mature solar energy utilization in the country\\ s city of Kunming, annual savings of 80,000 tons of standard coal, 11,100 tons of carbon dioxide emissions and 445 tons of sulfur dioxide. In addition, the use of solar water heaters are very economical for a family of three, for example, initial installation fee or three thousand dollars, but installed at least a day after saving eighty-nine degrees 1,000 yuan a year can be provincial electricity, 2023 to recover the costs.

Because of environmental protection, energy conservation, solar water heaters rapidly across the country, has reached an average of more than 10% utilization. Tibet, Yunnan and other areas with better solar conditions, the penetration rate has reached 30%, even in Jiangsu, Zhejiang, Guangdong and other solar conditions far better than the provinces, there are nearly 20 percent utilization. At present, China has become the world\\ s largest producer of solar water heaters and solar water heater market, to maintain world total holdings of 76%, and 20% to 30% annual pace. In the renewable energy industry, solar water heater industry has become China\\ s largest production scale, the greatest contribution, the highest level of independent intellectual property rights, and most widespread popularity of the green sunrise industry.

Hot summer and warm winter climate in our province, the province most of the time more than 3,000 hours of sunshine throughout the year, a year 4 / 5 or more conditions during the day with a collection of solar energy, solar energy utilization conditions are favorable. The province is to carry out solar energy research and development of the earliest provinces, but the slow progress in recent years, solar applications, solar water heaters mostly in hotels, schools, factories, and some research institutions, the general public rarely used. Solar water heater is always praised, penetration is very low.

In 2007, the Provincial Economic and Trade Commission, Science and Technology Department, Construction Department and the Department of Agriculture jointly issued a document, to speed up the popularization and application of s and promote the development of solar photovoltaic industry, and strive in 2010, the province\\ s urban and rural residents utilization of solar water heaters up to 15 % or more. Since then, the province has put forward new objectives using solar energy, urban and rural residents by 2010, usage of solar water heater to reach 30%. But more than a few years later, solar water heater is still hard for Cantonese Family: penetration rate of only 2% of the province has a strong, well below the national average, and falls far short of original goals.

Reason ? ?

Understanding and misunderstanding the policy is not implemented

Solar why it is difficult to enter public life? Guangdong Province Solar Energy Association, an official pointed out that people do not understand, management does not encourage, developers are not enthusiastic about is the main reason.

Guangdong people have the habit of bathing every day, a larger amount of hot water, supposedly saving and environmental protection should be more welcome to the solar water heater, but pervasive misunderstanding, such as fear cloudy impossible, for the first time such investment is too large. And some developers often affect the safety and appearance forbid residents to install solar roof. The province of small-scale solar water heater industry, technology is not mature enough, the product quality and after-sales service can not be guaranteed, the price is higher than traditional solar water heater products are not the main reason for people to agree.

Active or not management is also key. In Kunming, the relevant departments of the solar water heater installation is a clear-cut guidelines.

In our province, \"Guangdong Province public and residential building design and construction of s integration and acceptance of order\" are also being consulted, the \"Building Energy Conservation Regulations Guangzhou\" has not been scheduled at the end of the introduction. Reporters learned that the situation is that the current installed base of solar water heater is in a small number of residents did not report the case of \"stolen\" installed.

Province Solar Energy Society, supporting policies that are not related to the system, main features: First, the lack of a unified strategy to support policy, government decision-making still remain at the macro level, the mandatory application of solar energy development and utilization of the region\\ s lack of policies and regulations; second lack of system of economic incentives, lack of proper investors, users and related products, subsidies, price policy, low interest rate (discount) lending policies and system of tax incentives or mandatory tax policy.

Recommended ? ?

Installed in the design of government subsidized

Residents of the solar water heater for the existence of misunderstanding, the provincial experts explain the Solar Energy Society, Guangdong sunshine for a long time, the radiation is large, and each year is only 60-80 days a cloudy day, even on cloudy days solar water heater can also be endothermic, but also with electricity and gas use with fully meet the demand.

Quality problems for the water heater, he suggested that consumers should buy qualified products, these products undergo strict quality control, and by the installation of a dedicated staff to ensure quality and safety issues do not appear; the Government should strengthen the solar water heater market regulations, standardize the market order, the to implement strict access system; install solar water heaters should go through rigorous training and licensing system for implementation; government subsidies as appropriate, will play for the promotion of solar water heaters to the positive role.

For installation problems, experts believe that existing technology can be solved. Floors of low water large return pump can be installed, so cold water back to the rooftop water tanks; as long as the qualified products, installation and technical personnel with appropriate expertise, we would not have water leakage problems.

The biggest obstacle at this stage is still the visual impact of the housing, through the promotion of solar water heating systems integrated with the main building to solve, can be implemented in the building roof, \"wearing a hat project\", a unified installation of solar hot water system, so that both from the insulation of buildings, leak-proof protection, and to achieve rational use of solar energy.

Promote the use of solar water heaters in the process, the Government\\ s policy is crucial. In 2009, the National Development and Reform Commission, Ministry of Housing and Urban-Rural Development and other ministries accordingly started the \"Golden Sun\", \"solar roofs\" and other projects, solar water heaters were included in the \"home appliances to the countryside\" policy. Shaanxi planning long-term development plan of solar, Kaiyuan, Liaoning Province, recently introduced policies to promote use of solar water heaters, 100,000 households, household subsidies, $ 150.

Europe, Japan and other developed countries to encourage residents to use solar water heaters, in view of the initial investment is too large, the government will subsidize 3 to 6 percent. These practices can learn from the province.

Fortunately, some parts of the province is also actively support the use of solar water heaters, sources in Heyuan City, Fengyuan City community, 500 households by the Government to support the installation of a household, an annual saving of more than 60 million high-Po Chen-pu before the village to spend the majority of farmers are also solar water heaters. In Zijin County, and many houses have also set up on the roof of solar water heaters.
