Solar water heater industry slowdown much-needed break
[REVIEW] China\\ s solar industry has gone through 30 years, a number of in leading enterprises struggling to open up, this industry gradually gained market recognition. In 2009, solar water heater product was selected as subsidies for home appliance products, but also as a landmark event. However, when many companies are still immersed in the solar water heater 2009, the great development of the joy, the slowdown of the real mercilessly break their vision for 2010.
China\\ s solar industry has gone through 30 years, a number of solar water heaters in leading enterprises struggling to open up, this industry gradually gained market recognition. In 2009, solar water heater product was selected as subsidies for home appliance products, but also as a landmark event. However, when many companies are still immersed in the solar water heater 2009, the great development of the joy, the slowdown of the real mercilessly break their vision for 2010. Many small businesses face the cut-off or close down, how solar energy companies in the new round of competition will survive?
Slowdown, the industry reshuffle curtain in recent years, national policy support, in particular, driven by policy of home appliances, solar water heater industry, there has been explosive growth, which caused many companies for 2010 high hopes for sales of solar water heater industry, upstream and downstream companies are constantly expanding production capacity. Large enterprises have set up factories, for capacity allocation; small businesses to be outdone, launched the production line; the same time, the upper reaches of the solar water heater parts business also continued to grow, making a substantial increase in market supply. In 2009, the policy of home appliances under the stimulus, the purchasing power of rural market to be released, the industry also seize the opportunity to achieve explosive growth; into 2010, China\\ s urbanization process moves forward so that many villages are being merged into satellite, making the high degree of dependence of rural enterprise market some of its retail purchasing power is suppressed, rigid demand decreased.
Subjective expectations too high, the objective of oversupply, overcapacity, the main reason for slow growth is induced. Significant increase in corporate supply, market demand has declined, more intense competition among enterprises in the shift in the situation, the slow pace of development is normal.
Cut-throat competition, the market calls for brand concentration
The solar industry with low barriers to entry, profit margins, the market was mixed, the growing polarization between enterprises. Large number of no-name brand to be the impact of low-priced products; small brands will need to continue to lower prices to get the living space; the middle of the corporate brand is difficult over large enterprises, small on price but no match for the workshop produced no-name.
The result of vicious competition in the market is the decline in profitability and sales. First half of the data show that eighty percent of the solar water heater companies have varying degrees of declining sales, inventories and other issues. From the current situation, the solar water heater industry will become less and less profit, brand concentration and firm size is the trend.
Many big brands can use the power of the brand in the homogenization of thousands of serious s in Deus Ex. By the shuffling process industry, solar water heater industry should make structural adjustment and industrial restructuring and improve the brand concentration, encourage enterprises in scale, technology can be improved, providing better products to market.
The rural market is becoming saturated, should seek new breakthroughs
Over the years, the development of solar energy companies rely mainly on the rigidity of demand in rural market pull, but after 10 years of development, the national solar energy solar energy in rural areas to promote sales of developed areas has become saturated, especially in Jiangsu, Zhejiang, Shandong, Henan and other solar consumption province. To break through the bottleneck, companies must have to the city, to seek new breakthroughs in high-end.
The development of engineering sector in recent years the market is a major highlight. In recent years, with the state can support efforts to increase renewable energy and building energy efficiency indicators improved, more and more cities are choosing solar energy as a complete \"green index\" tool. It is understood that, early in 2006, Shenzhen, clearly defined, with the conditions of the solar collector the following new 12-storey residential buildings, the construction unit should be configured for all household . Since then, many provinces have launched a similar local policy. As the main origin of the solar water heater, Jiangsu, Shandong and Zhejiang is the reduction in solar assisted building walked on ahead. Place mandatory installation of solar policies have been put to the rapid development of the project was the market. Although sales of solar energy is still the greatest contribution to the rural market, but the urban market will continue to be the next major market, the mainstream product projects from one machine to the transition.
Solar province, Jiangsu Province, Jiangsu led the development of solar thermal, photovoltaic application of technology and market maturity in the country has been in a more leading position among the nation\\ s top three solar water heaters, and Beijing, Shandong, par, value of 200 billion more than 300 enterprises, the formation of a number of domestic and international competitive brands and products. China solar water heater products in the countryside, the province has sun, rain, Hua Yang, glory, Sunshine, per liter, on profit, Bedford Wright and other 15 winning, solar hot water project in the district, schools, hospitals and industrial has been promoting the use of a large area.
September 1, 2006, Jiangsu officially implemented a new report on \"Residential Design Standards, Jiangsu Province,\" mandatory \"new residential solar water heater should be centralized configuration system.\" In 2008, Nanjing, Jiangsu province and is provisions, new 12-storey hot water supply system must use solar water heaters. According to the above provisions, Jiangsu rapidly around the action, including design, plan approval, construction, quality inspection departments and real estate developers, whether active or passive, strict implementation of government regulations to force the use of solar water heaters.
As the new products, the advent of new equipment, can now mandatory for any residential solar water heaters, high-rise, high-rise, four air source heat pump can be used above conditions are ripe, to promote solar water heaters, solar energy is bound to accelerate the development of Jiangsu .

market ushered in the cold is over a small sun
[REVIEW] 2010, as the world economic crisis, \"fever\", the global economic recovery; home appliances to further advance the pace of new rural construction, etc., will make into the golden period of development. This is undoubtedly so that the general solar entrepreneurs are very excited, have been gearing up a big fight. However, a reversal of previous years, the vagaries of market supply and booming phenomenon of the spring, sales suffered a \"small cold\", no doubt to many companies splashed a pot of cold water. \"3.15\" and \"May Day\" holiday sales and other major effect was significantly reduced. At present, some of the production in a semi-stagnation, do not know how to deal with the situation.
2009 China solar water heater market in the global financial crisis spreads, market competition and other factors, remains more than 30% increase in rapid development. The reason is that in the country to vigorously promote energy conservation, new rural development and promotion of policies such as home appliances, solar water heaters to environmental protection and energy saving advantages gradually accepted by consumers. The end of 2009, Premier Wen Jiabao on the World Climate Conference in Copenhagen, for the first time that China is the world\\ s solar water heater installation space superpower, and said it would develop new energy sources such as solar water heaters and renewable energy. In 2010, as the world economic crisis, \"fever\", the global economic recovery; home appliances to further advance the pace of new rural construction, etc., will make solar water heaters into the golden period of development. This is undoubtedly so that the general solar entrepreneurs are very excited, have been gearing up a big fight. However, a reversal of previous years, the vagaries of market supply and booming phenomenon of the spring, sales suffered a \"small cold\", no doubt to many companies splashed a pot of cold water. \"3.15\" and \"May Day\" holiday sales and other major effect was significantly reduced. At present, some of the production in a semi-stagnation, do not know how to deal with the situation.
\"My investment is several times greater than in the past, why the season has been frozen, the problem lies in where?\"
\"I\\ m in marketing and management has done a lot of adjustments, and increased support, but no opener?\"
\"Dealers do our best under the leadership of sales, using a variety of promotions, sales are still not clear up.\"
What companies have started to reflect on their own where the problem lies in the future the market will show what kind of trend it? Industry reshuffle is officially opened … … market rare \"cold spell\" cause that?
Analysis of \"cold spell\" of the six root cause
Chinese New Year I have been in the market line with the dealers and consumers communicate, and communicate in depth with some of the entrepreneurs, their analysis that the market has been a \"cold spell\" because the performance of six major factors.
1 competition: the beginning of warm boiled frog
In recent years, the industry has maintained rapid growth, 08,09 economic crisis let people see the tremendous opportunities the industry, some have been externally oriented businesses, such as old appliances business began to have fought in the solar water heater industry. Companies in the industry is in many ways under the foot, fully prepared to meet the golden period of development. Successful home appliances brand in 2010 reached 171, medium and small brands began to compete in the market. In product, sales and other serious homogenization, the company began a price war. March and April in particular is the best time investment, some local enterprises to open the same day there will be investment to support policy efforts to a more than a big, big flame starting price is also available.
Xi\\ an City is well-known solar boilers, solar water heater market. I found that the market is about 300 stores, some five or six brands of store operations, a variety of brands could be seen. The wholesale store sales staff to see past guests began selling. \"Sir, to see what kind of solar water heater products, our home cheap, what brand to have.\"
U.S. vice president Zhang Jiangping largest solar company said that at present a large number of dealers because of lack of information, did not give their exact location, lack of comprehensive ability to judge, do not know what kind of brand selection; and manufacturers could not find a dealer is. During this time, hovering at a loss, the dealer inadvertently care stores, not to mention marketing, and this led to a lot of brands in the local market sales decline.
In the course of my research found that in the store-lined streets, many solar energy and store the image quality is not high, but less attractive. The store mostly play a decisive role in the Purchasing Guide lack of product knowledge, product selling elaborate enough, basically no sales techniques, image quality is poor, lack of communication such as affinity, ultimately, the price issue. I Zhejiang, Anhui, Henan and other provinces of stores Purchasing Guide exchanges. Purchasing Guide is not very clear that many ordinary vacuum tube with three executives of the difference, just know that there are differences or whether the price was not the same as thermal efficiency, specific differences is not clear how much, let alone to explain the technical aspects of friends.
New Energy Co., Ltd. Zhejiang Yang Chen Yang, Hong Kong Hong Kong said that at present only a few large enterprises in the industry for the terminal Purchasing Guide for information on training, leading to the terminal or by a large number of Purchasing prices to attract consumers. Price war can not build the brand, which is universal. Yang Hong Kong in addition to solar energy company focused on training, but also to invite the experts in time-to-end guidance.
Development trend in the industry, driven by the development of enterprises so smooth, basically at the \"pampered\" state, and this \"cold spell\" so that they began to wake up thinking about how to deal with more intense market competition.

Transformation of to get rid of the low-end innovation dilemma
Hey! Streaker who. Only produced to give the interests of consumers satisfied with the product, this is really good product. Only the transformation of innovation, only to get rid of low-rise high-value dilemma, is the only way out.
Solar water heater market given the cold shoulder, indicating that the industry entered a period of adjustment, to suppress the low-end products, and guide the transformation and upgrading, has been the industry consensus.
There are a number of unscrupulous companies set off wave after wave of low-quality low-cost in the war, and spread to the countryside into the solar home.
Poor quality, no after-sale protection, leading to complaints, the industry\\ s reputation damaged, the results cast a roof waste, which is the industry soil do not want people to see.
More appalling behavior is streaking threw a veil. Not long ago someone threw a \"White Paper\" of the veil, and now some people dressed in \"public,\" the veil, one after another.
This \"public\" the veil is a well-planned control instruments business, is easy to see one of its goals to attract the eye to show his leadership, the second is price war ignited bare dominate the market, really ulterior motives.
Solar water temperature control meter is an electronic products. Its raw materials, the main circuit board equipment dollars, solenoid valves, transformers, resistors, capacitors, transistors, transistor, thermal components, wire, silicone, stainless steel, chips, shell and other components. Purchase price of the upper and lower cost several times, such as basic good dozen dollars a chip, not only poor binary, which gives businesses a cheap war a lot of room.
\"Domestic controller\" GB/T23888-2009 release and on the implementation of national standard, but the technical requirements of the indicator is difficult to detect, has not yet been any form of supervision and sampling, but also for the unscrupulous to create a fake made bad business opportunity.
Water temperature sensor is no breakthrough technology changes, temperature, furring, interference, lightning, short life has not yet been completely solved, in the homogeneity and gave an excuse to have a low-quality low-cost war.
Confusion in the market, control instruments are complementary products or end products, the same product to the whole enterprise OEM package, but also in the market to build distribution channels, retail outlets, price confusion, contradictions and tangled, but also for providing low-quality low-cost war battlefield.
High frequency transducer repair, repair during the year to be replaced 1-3 times, maintenance costs are basically fixed, the discount can be lost through the sale of guerrilla burden, reduce maintenance costs with new tactics.
This has been a hotbed of streaking. So there are some unscrupulous companies the chance to make a mad rush to come lead the way. Not long ago a group came streaking Baotuan information, leading them to compete with low price by 15% naked, taking over and then Ben, really chilling.
In transition, the times call for our industry should be dispersed from extensive to intensive concentration, from investment-driven to innovation-driven, from low to high value-added industrial sectors, from the traditional to the modern system runs from from quantity expansion to quality improvement changes . But there are so many of our industry on a number of small business owners, still naked price bolted, shame.
Hey! Streaker who. Only produced to give the interests of consumers satisfied with the product, this is really good product. Only the transformation of innovation, only to get rid of low-rise high-value dilemma, is the only way out.

Property installed ban
\"Wuhan is now building \\ two types\\ society, but the owners want to install , to prevent the property has been installed.\" Recently, Qiaokou Changfeng Garden District Avenue-day ground reflect dissatisfaction with the owners Mr. Hu.
Hu said that early last year, he moved Qiaokou Garden District 9-day ground floor, the top 18 after buying a solar water heater, ready to be installed on the roof. Property that may be in accordance with relevant laws and regulations, he can not roof tops. Coordination with the property many times he failed, so far put solar water heater in the living room for a year and you still do not have access.
Reporters recently found to accompany residential property Yujing Li Hu, its introduction, many stay at the property owners have proposed to install solar water heater requirement, the property were not agreed, for two reasons: under the \"Property Law\" and this year January 1 implementation of the \"Wuhan City Property Management Regulations,\" provides: residential common areas, platforms, roof is jointly owned all owners, private individuals can not be accounted for. Some owners to install solar water heaters in the roof, according to relevant provisions of the residential property owners would have to wait two years after its establishment, the organization of the Building Industry Authority by the unit owners signed consent to it the whole floor.
Yujing Li said, long after the installation of solar water heaters produced by the static pressure will lead to roof leakage, seepage and this is not the developer promised five-year housing warranty. In other words, once the roof water seepage, only five years after the use of the owners house maintenance fund repairs, which have all or at least the BAN unit owners to sign an agreement, because the roof top water seepage is generally only affect tenants, other floor tenants agree to the use of funds is difficult to say.
Reporter\\ s inquiry into last year, April 1 implementation of the \"Renewable Energy Law\" Article 17: The State encourages units and individuals to install and use s, buildings have been built, residents can not affect the quality and installed under the premise of safety products meet the technical specifications and standards of the solar system.
It is understood that the days of ground around the Garden District, many real estate owners to install solar water heaters were not restricted.

Weapon professional buying guide
With the development of solar thermal technology, have become essential to our \"family members\", but about water heater to buy, a lot of people but it is ambiguous, what kind of water heater can be used with comfortable, safe, professionals to help answer your questions.
Advantages: solar energy, more environmentally friendly, energy saving, safe and economical.
Disadvantages: complex installation and maintenance problems. In addition, hail, high winds, cold weather, water heater vacuum tube solar collector tubes prone to cracking phenomenon. If there is no electric power Accessibility Accessibility is not doing enough or professional, rainy weather or winter may not work properly.
A wide range of solar water heater product categories, according to different classification criteria can be divided into the following categories. By can be divided into categories: vacuum tube and tablet.
Performance can be divided by the tank pressure: pressure and non-pressure type.
According to the structure and installation can be divided into: one and split.
According to operating mode can be divided into: natural circulation and forced circulation type style.
According to installation location can be divided into: rooftop and balcony style.
Key components
Solar water heater has three main components: water tank, stand, collector.
Tank: the tank is the heart of solar water heater parts, mainly by the shell, insulation layer, interior components, galvanized steel casing or spray usually selected steel materials that not only high strength, corrosion resistance is also good. Select more than 40mm insulation layer of polyurethane insulation materials, fine texture and a good polyurethane foam, foam pore size uniformity. Good water tank generally with a thickness of not less than 0.5mmSUS304-2B food grade stainless steel or enamel steel liner is made of durable anti-corrosion, high temperature, can keep the water clean.
Stand: as the bearer of the weight of the entire water heater parts, and its quality directly affects the service life of solar energy, solar stent on the market generally use galvanized steel or aluminum, in general, the main lever bracket fold thickness ≥ 1.5mm , the other not less than the thickness of the force rod 1.0mm. Collector: vacuum tube collectors in the choice of the film color should be chosen small, the vacuum tube should brand identity. Flat-plate collector should choose full copper core design of the selective absorption coating spray collector, flat collector surface should be high-strength low-iron wove glass, in order to ensure good light transmission and strength.

Prepare into the city
In the future, solar energy to high-end, to seek new breakthroughs in the city has become the industry can not avoid the question.
For solar water heater industry, is the nexus of the year 2010. Prior to the development of solar water heaters rely mainly on the rigidity of the rural market demand-pull, but after 10 years of development, Jiangsu, Zhejiang, Shandong, Henan, solar water heaters do better in rural areas to promote the sales market has become saturated. In the future, to the end, to seek new breakthroughs in the city has become the industry can not avoid the question.
Technology: innovation-driven product upgrades
From the end of last year, s began to force the leader in high-end, technology innovation-driven product upgrades.
Reporters learned that China\\ s solar water heater industry with hundreds of billions of market potential. However, the traditional solar water heater solar energy industry can not meet the development needs and market demand, complex production process, the metal liner insulation is poor, single function and so allow the development of traditional solar water heater appears to falter. Emperor Ming Huang Ming, chairman of solar water heaters warned that if the solar water heater industry, long-term stay at a low level of competition, the industry is difficult to improve.
Norit New Energy Co., Ltd. Deputy General Manager Liang Wen-Zhe believes that China\\ s solar water heater industry, if you want to embark on rapid development of the channel, it is necessary to achieve from the extensive development to the fine developments. Technically, the industry to high-end developments in the field.
In this context, from the end of last year, domestic solar water heaters began to force the leader in high-end, technology innovation-driven product upgrades.
Earlier this year, four seasons Mu-song of Things technology for the solar water heater, launched the world\\ s first solar water heater things. Emperor Ming, Marino, the sun rain and other enterprises in the overall layout of the high-temperature solar water heaters. Compared with ordinary water heater, the temperature control products for industrial production for the domestic use of solar thermal expansion of new areas. Not long ago, China\\ s first solar thermal power projects built in Beijing, the Ming emperor to become the project\\ s key technology partner. The Marino\\ s high temperature pipe technology and technological achievements in the completion of project identification, the successful sale. Sun Bao health technology is the solar force, launched China\\ s first healthy bacteria with UV solar water heater.
Market: rural \"surrounded by\" City
Affected by the construction planning, consumption habits, product technology and other factors, solar water heater business, \"city\" is doomed to not be smooth.
In people\\ s minds, the main battlefield of solar water heaters in the countryside, the city only a supporting role. However, the actual development of the industry\\ s situation is not necessarily the case.
With the development of building integrated solar energy competitive situation and the formation of the rural market, solar water heater companies will gradually differentiate into two types: one is living in the rural market of small and medium enterprises, and the other is constantly expanding and building integrated solar market , take the route of the big city brands. This is the reporter often heard view.
Huang Ming is the one fans point of view. He said: \"The solar market in the broader urban rather than rural.\" Because, compared with the rural market, the city population receptive to higher-priced products, this way, products, profits will be higher. As early as 2002, solar heaters set up a home to the company and built a number of solar energy and building integrated real estate. Norit is also committed to building integrated solar energy. As awarded by the Ministry of Housing and Urban-Rural Development of the solar industry\\ s first \"national domestic industrial base,\" Norit three years to complete the promotion of 34 million square meters of area.
But by the construction planning, consumption habits, product technology and other factors, solar water heater business, \"city\" is doomed to not be smooth. In this regard, Li Jun, president of Four Seasons Solar Mu song recommendations to strengthen the rural market should be based on the Plough, accelerating the expansion of urban markets, in particular, to help countries to build 10 million units of affordable housing policy opportunities to low-carbon products to build low-carbon buildings.
Trends: looking forward to enforce standards
Mandatory standards for the short term may not be able to play an immediate effect, but in the long run, is bound to promote the industry to a higher level.
It is understood that China\\ s solar water heaters for the production and did not implement \"production license system,\" most of the solar water heaters generally do not use electricity, do not need China Compulsory Certification. Although the state has introduced a solar water heater national standards related to product quality, but all the sale 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.
At present, China\\ s solar water heater industry, a total of 23 national standards, but are recommended standards, companies can refer to, but without enforcement, which to some extent, resulting in domestic solar water heater industry, \"mixed bag\", the market access threshold is not high. Statistics show that domestic OEM water heater solar water heater market, accounting for more than 20%, this so-called OEM products for the solar water heater market, the negative impact should not be underestimated.
In view of this, starting in 2010, a group of standards and industry self-regulation policy document intensive.
In 2010, 16 ministries and commissions jointly by the state issued a document of \"domestic s and energy efficiency limits the efficiency rating\" to start. This is a solar water heater industry\\ s first national mandatory performance standards, means that in the future those who enter the solar water heater industry, enterprises should implement this standard.
In addition, solar water heater energy efficiency standards have also been completed at the end of October 2010 all the development work. Recently, the Chinese Renewable Energy Industries Association Professional Committee of Zhu Junsheng said that the standard has been reported to the State Standards Committee, after six months is expected to introduce. The standard will be revised energy efficiency standards for 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.
Insiders pointed out that the implementation of these mandatory standards will raise the threshold for market access of solar water heaters, regulate the industry. Although the short term may not be able to play an immediate effect, but in the long run, is bound to promote the industry to a higher level.

Expansion of market in Hubei
Control light and heat resources so rich, but the province into this business without wealth. According to Zhou Yanjiang of Mocha, in Hubei Province, more than 2,700 solar energy sales companies, only 150 solar energy manufacturers, machine manufacturers, and which is almost negligible.
American professor Paul Luohuo Ken in his book \"The Ecology of Commerce,\" pointed out: If human beings do not now, \"industrialism\" business model to \"ecological Marxism\" business model, companies will put the community into the grave.
For each person, this is by no means an alarmist, but a real pressure. To create a sustainable business model, the world phase of the solar energy industry, will be regarded as one of the few potential growth industries, the state Department of Housing and other departments in the country more than ten cities worked hard to pursue. \" thermal wall plan \"and\" photovoltaic roof program. \"
China is the world\\ s largest producer of and users, and in Japan and Germany as the world\\ s third largest producer of photovoltaic products. Now, the state is to conserve energy, develop renewable energy identified as the basic national policy. In this context, how to promote the development of solar energy industry in Hubei Province to become a serious problem.
Expansion of solar water heater market in Hubei Province
Recently, Hubei Province, solar water heater industry Association Zhouyan Jiang introduced the use of Hubei Province is solar areas with better conditions, the province\\ s land area nearly two-thirds of the number of hours of sunshine hours in 2000, the annual total solar radiation is greater than each m 4000 megajoules of solar radiation values ??in the equivalent of 731 tons of standard coal.
Despite such a wealth of light and heat resources, but this province has not translated into business wealth. According to Zhou Yanjiang of Mocha, in Hubei Province, more than 2,700 solar energy sales companies, only 150 solar energy manufacturers, machine manufacturers, and which is almost negligible.
According to statistics, Hubei Province, more than 90% market share by Emperor Ming, Sun Yu, Qinghua Sun and other Foreign brand occupies, leaving the local company\\ s market share less than 10%. Moreover, the vast majority of local enterprises are SMEs, brand awareness does not ring, from the point of customers and referrals rate is not high.
Zhouyan Jiang disclosed, Hubei Province, the penetration rate of in the city of 20%, only 5% in rural areas. Although penetration is not high, but the Wuhan City has become the second largest solar water heater sales, second only to Jinan. With the national policy drivers and residents awareness of environmental protection, will increase the penetration of solar water heaters, the market will be further expansion.
Solar water heater industry is still in the storytelling stage.

Can high-rise buildings to install
June 16, Lee reflected, she did not live in a unified high-level residential installed, the property they want to be informed when the installation does not allow unauthorized installation of solar water heaters. Residential property that residential construction in order to maintain the unity of style, the relevant departments of the high-rise buildings do not allow owners to install solar water heaters. \"Now the country attached particular importance to energy saving, how can you not allowed to install energy efficient solar water heater it?\" Ms. Lee is very confused.
Ms. Lee told reporters, her living quarters for the construction of the road a senior community, not all of the real estate community to install solar equipment. Ms. Lee had just moved in six months, due to not allow the installation of solar water heaters, so some time ago bought a Taipower water heater, but a month down the extra hundreds of dollars to tariffs particularly distressed that Ms. Lee. \"I had been using the solar water heater, although summer water consumption, but also a month with a few dollars more than usual water only, since the installation of the electric water heater, the electricity spending was up.\"
Reporters learned from the city housing construction sector, March 2010, Municipal Construction Committee and the Municipal Council by letter six departments jointly issued the \"speed Liaocheng promote the use of solar thermal systems implementation of views\", said the use of three views time, the city\\ s urban solar penetration from 20% to 50%. Comments after the implementation of urban multi-storey high-rise buildings and solar installation rate has improved significantly. Ms. Lee are living in residential construction time earlier, so the installation of solar energy is not uniform policy provisions. At the same time, said the staff, residential property owners to install solar energy to prevent the practice, and there is no legal basis, should be mainly for security reasons, so the owners can install solar on the problems and property to continue consultations.

Quality enamel interior upgrades
In recent years, more and more consumers increasingly tend to use enamel interior material of solar products, and abandoned stainless steel liner. This means that more and more popular in the enamel interior, .
From the technical point of view, the interior is the heart of solar water heaters, and its performance affects the overall product life. As the stainless steel liner technology easy to implement, production equipment, R & D costs are lower, the vast majority of products on the market uses a stainless steel liner. However, the stainless steel liner susceptible to corrosion, easy to absorb deflated, pressure defects such as poor performance has been unable to solve. The enamel interior is durable and has a pressure, anti-corrosion, anti-smoking flat, clean water and other features, has been popular in the field of electric water heaters, solar water heaters will also upgrade the liner of choice.
From the market, the enamel interior solar market share increasing rapidly, especially in split-pressure, balcony hanging solar energy project to demonstrate superior performance of the market, but also more and more manufacturers and real estate agency\\ s attention, and thus become pressure solar project of choice. The industry believes that the future development of solar water heater industry, market pressure will become the dominant application. Stainless steel liner era is gradually during the transition to the enamel interior.
National Cheng Kung University to replace stainless steel liner enamel interior trends
It is reported that split pressurized, hot water system in the balcony wall of the tank has now been largely achieved enamel interior to replace stainless steel liner. In this area, enamel interior has more than 70% market share, the other is stainless steel, rotational molding liner. In 2010, Xi\\ an balcony wall of a real estate tender scene, nine solar companies to bid, of which seven companies enamel is used in light water tank. The top 50 companies in the industry, more than 80% of the companies and light tanks supporting the cooperation with the business. This fully shows that enamel interior tank has become a must-pressure tank.
And one for non-pressure solar water tank, it seems 90% of manufacturers are using stainless steel liner, enamel interior, although the share is very low, but substantial growth every year.
Stainless steel liner products have limitations
As the stainless steel liner technology easy to implement, production equipment, R & D costs are lower, the market for more than 90% of the product is used in stainless steel liner. Stainless steel solar energy in the \"open\" state without electric heating, the use of better, and longer product life, which is the rapid spread of solar products to advantage. However, once installed electric heating devices, especially the use of a pressure-type operation, stainless steel liner products have significant limitations.
Insiders said that the early solar industry technology is imperfect, there is no installation of electric heating devices, but with the maturity of technological innovation and increasing consumer demands, and now most solar water heaters installed electric heating equipment, pressure solar water heater much greater users.
This is equivalent to have a solar water heater electric water heater function. However, the \"heating\", \"pressure to run\" and other features of the application, the stainless steel liner has appeared in the field of electric water heaters, \"corrosive\", \"water quality perishable\" problem incidents in the solar water heater is also often, problem can not address the root causes. Once Addressing the root causes, the only way is to upgrade the tank.
The future of solar energy market must be the main battlefield of the city, which means that high-level split with the City of small solar energy will become increasingly popular in the city, split solar energy requires a certain pressure, while the cost of stainless steel more expensive, many manufacturers In order to reduce costs, make use of thin stainless steel liner, usually only 0.6 ~ 1.0mm, voltage capability down, water heater leaks more easily, directly affect the life of water heaters.
Stainless steel liner and a maximum risk – \"weld.\" Stainless steel liner biggest risks is the \"seam\", 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 easy by corrosion of chloride ions in tap water, bring to the water pollution.
Have the advantage of enamel interior
In contrast, enamel interior is the high-tech products, in the thick cylinder liner surface enamel, enamel metal material, together with seamless welding technology, can bear a greater range of temperature changes, usually in the range -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 resistance, water vapor, a variety of ions can not penetrate its surface are, can not effectively ensure the quality pollution.
Industry experts say the popularity of enamel interior is split solar inevitable. There is no doubt that the enamel interior adapted to the high level of foreign consumption, health and a strong sense of family and unit needs, sales soared. Most importantly, enamel interior areas of the world wide spread of solar power split, enamel interior revolution has become an irreversible trend.

Haining in line to the European standard
for energy saving have become the \"low life\" of the preferred water heater. Haining as one of the three largest solar energy industry base in recent years suffered overcapacity problems.
Gas prices high. Solar water heaters for energy saving have become the \"low life\" of the preferred water heater. Haining as one of the three largest solar energy industry base in recent years suffered overcapacity problems. To this end, the local control to enhance product quality, expand exports, the number and value of exports this year to maintain double-digit growth.
European standard requires a higher
Recently, the province is located in Haining solar product quality inspection center successfully passed expert review and acceptance, mark the center with basic European standard EN12975, 12976 detection.

Among them, solar thermal power generation is on the first place, which means \"five\" period, the state will vigorously promote industrial policy light and heat generation and its related equipment.
Province of solar product quality inspection center responsible person said, Haining solar energy industry base in line with \"directory\" to develop the direction, some companies have started research in high temperature solar energy product development and utilization, which is the solar industry to upgrade Haining significance.
Solar water heaters are often used to
How the selection and proper use of solar water heater? Province Solar Product Quality Inspection Center staff, estimates that the average person shower of water roughly 50 liters of water a little more female shower. Number of consumers in the choice of pipe shall be based on the actual situation of your own home computing, and a slight surplus, to ensure that the winter or rainy days can be used normally. \"Solar water heaters should always be used because the tank\\ s normal temperature is kept between 50 to 60 degrees Celsius, easy to breed bacteria.\"
