     2010, the solar water heater successful home appliances relevant information has been published, 168 of this successful enterprise, involving 186 brands, 1337 model, the successful marketing of 31 provinces and autonomous regions. The bid relates to the number of brands, more models, greater price range.

First, the 2010 Basic solar home appliances
    1.2010-year total and type of successful business
    According to U.S. research center for large solar water heater in 2010 related to successful data management statistics, a total of 168 companies in this bid, more than 2009 out of 76 corporate publicity. The two types of business enterprises successful publicity. Among them, the second 79 successful enterprises publicity, publicity companies bid for the first 89.

    The number of successful public companies with 24 home appliance enterprises, accounting for 14.3% of total successful companies, although the proportion in 2009 declined by 6 percentage points. However, the absolute amount of increase than six in 2009. Haier solar energy, solar energy Hefei Meiling, Hefei Rongshida solar, Guangdong Midea, Henan fly solar energy, solar energy, and all successful Shandong ducklings.

    2.2010 Source distribution of successful enterprises
    According to the published results show that the number of successful enterprises in 2010 168, from 16 provinces, more than two provinces in 2009 were: Jiangxi and Shanghai. Of which: number of successful enterprises of Zhejiang highest number of 39, accounting for 23.2%; Jiangsu Province, winning 32, the proportion was 19%. Third and fourth respectively in Beijing and Shandong Province, the first four provinces, a total of 117 successful companies, the cumulative proportion of 69.6%.
 
    Comparing 2010 and 2009 found that the regions of successful enterprises, Zhejiang, Jiangsu, Yunnan and Shandong to increase the amount of the most successful companies, which increased 24 Zhejiang, Jiangsu, increasing 17, an increase of 11 Yunnan, Shandong, an increase of 9. This is to some extent, shows that China\\ s solar thermal industry cluster advantages are highlighted, Zhejiang, Jiangsu, Shandong and other emerging industrial base of powerful enterprises. Yunnan, but also should be noted that the rise of the solar thermal industry, Yunnan is China\\ s early development of solar energy heat utilization industry, one of the provinces, but in the development process and other reasons because the product has been in a tepid state, but recent years with the rise of flat panel solar water heater, the Yunnan government policy of increasing support, Yunnan Province, the solar thermal industry is developing rapidly in recent years.
 
    3 Distribution of the number of product lines
    The list of successful publicity, the average number of brand bidding model 7.7, up from successful models to reduce the average 1.1. The gap between the number of companies to bid for larger models, the introduction of models of the brand is the most sun, rain, launched 50 models, an increase of 20 over last year, while the same 12 brands launched only one of the models. Combined strength of enterprise-scale perspective, corporate reputation, and size of the stronger companies to bid for more models accordingly. Distribution of the whole model number from the situation, model number from 1 to 4 the number of brands between the proportion of 46%, the number of models 5-8 the proportion between the number of brands was 25%, both the total the proportion accounted for 71%, up from the successful range of proportion with an increase of 8 percentage points, more than 70% of the brand product model number of the tender were 8 or less.
 
    Major U.S. research centers on the successful 2009 sales analysis of 74 companies found a single successful brand marketing capabilities provinces (large definition of the U.S. research center: a single province sales ability = 0.3 * 0.7 * Registration Registration delivery sales volume) and brand Model number of the correlation coefficient of only 0.11, showing a very weak positive correlation. General trend is more tender model number, the higher the ability to sell a single province, when the volume of product models to reach more than 13, this positive correlation is more obvious.

    But this is only a general trend, overall very flat, which means that a single model through increased product sales volume to increase the capacity of the general effect. Research recommends that companies large U.S. market with the number of standard models the strength of enterprises linked to different types of products in a way tailored to certain groups, will require different marketing strategies, strong enterprises, to implement for different segments corresponding to the marketing strategy, and some weaker companies to catch up. Therefore, companies should not blindly pursue to increase the number of product models, but to the strength and business and marketing strategy is consistent.
 
4. Price distribution
    The tender price has increased, some high-priced products into successful series, the average price rise, the price range widened. According to the publicity results show 186 brand-name products, the highest price of 5,000 yuan, higher than the previous successful release of 1,000 yuan, the lowest price of 1,000 yuan, lower than the previous successful release of $ 220. The average bid price of 3409 yuan, higher than the previous average price of winning 588 yuan. Look at the specific price range from the distribution of 1,500 yuan products rarely, only 0.1% share, the price to 2,000 yuan in 1500 the product accounted for 4% of the national product. The most concentrated product prices between $ 2500 to 4000, the product in this price range accounted for 58.7% of all products, 4,000 yuan more than the proportion of products also reached 25%.
 
    From all over the bid price of the product to see, Chongqing companies to bid for the product is still the highest average price for 4430 yuan, higher than the national average price of 1021 yuan, and higher than the average of the last bid price. The average price of Hebei Province, enterprises are still the lowest bid for the 2577 yuan, lower than the national average price of 832 yuan, but the average price of winning than the previous Hebei higher than 810 yuan.
 
 
    Successful brands from the 2009 features, the brand with the average price of a single province of the ability to sell the brand almost no correlation. Ability of a single province in 2009 sales of top ten most companies, there are five brand price lower than the overall average; the other five companies, national brands are strong, to take a higher pricing strategy, evenly divided.
    5 bid price span of
    The successful brand price span (the highest price and lowest price gap), an average of 1761 yuan. Price span for the three brands most light general, Hawker and Haier, the price span was 3631 yuan, 3340 yuan and 3300 yuan. Price of the smallest span three brands were filled liters (260 million), the sun Colmar ($ 200) and Tianfu Sunshine (160 yuan). The product price has increased, so winning products span the whole is greater than the 2009 price level.
    From brand to see the price gap between adjacent products, this successful brand spread to the adjacent average 268 yuan, the smallest of the three adjacent spread brand sun, rain, sun and seasons Mu-song treasure, the spread was 57 yuan, 64 yuan and $ 75. Spread the largest of the three brands to Macao and Germany gentry, warm blessing children, MACRO, 1890,1150 and 1070, respectively, spread yuan.
 
    From 2009 to see the successful sales of the brand: the general strength of the firms that are less successful product model number, if the widening spreads will lead to a single sub-products into different market segments, leading to competition in a market segment in a single product less competitive, sales weak; companies stronger, larger number of successful models, covering the low end of high school, so a larger spread, and such enterprises should be appropriate to widen spreads to widen spreads can be as reduced with enterprise products in the same market segments to form internal friction.

    6 successful areas of successful brand
    2010 168 winning companies, the average winning 14.6 provinces, 3.6 higher than 2009 provinces, showing that this bid has been expanded. 168 companies, most successful 31 provinces and autonomous regions, such as: Oster, Haier, Hawker (Shandong Hout Solar Co., Ltd.), Emperor Ming, Victor (Hefei Rongshida Solar Technology Co., Ltd.), Wing thing of the four seasons Mu-song, sun, treasure, sun, rain, 100 million and per liter; at least the only one provinces and autonomous regions. Among them, winning 1-5 all the provinces of the brand share of successful brands accounted for 17.3%, 12.5 percentage points than the 2009 high; winning 5 to 10 provinces of the brand share of 18.2% over the 2009-year high of nearly 5 percentage points ; winning 11 to 15 provinces of the brand share of 29.5%, the largest number of successful brands in this range than the 2009 high of 15 percentage points. Winning 15 provinces and the following cumulative proportion of 65% brand, much higher than in 2009, indicating less successful provinces in 2010, a substantial increase in the brand, to a certain extent, shows the number of successful small and medium enterprises in 2010 the ratio increased.
 
Second, the winning bid of regional and key markets
    1 the basic situation of winning the regional
    The announcement of the bid area to the 31 provinces, each province of the market average number of successful brand 87.6, compared with 2009, more than 34.2 53.4. Since 2010, a significant increase in the number of successful brands, so each province is basically the number of successful brands have increased compared with 2009, but the province has shown different characteristics, this reflects the different target market of corporate marketing, also reflects the country\\ s solar energy market is currently hot and cold conditions and layout.
    Henan, Hubei, Anhui, Hebei and Sichuan, the number of market-winning brand of five provinces, according to the provinces successful brand sorting, the first four provinces and in 2009 the same; Sichuan Province, a substantial increase in market successful brands into fifth place. Among them, Henan market has been favorable for successful brand in the market, there are 71 brands in 2009 winning the province in 2010 increased to 155, more than doubled, with 83% of the province\\ s brand bidding market, again ranking first; Hubei market the second largest number of successful brands, winning 144 brands, more than 82 brands in 2009, an increase of 132%; Anhui market in 2010 winning 131 brands, 68 higher than 2009, an increase of rate of 108%; Hebei market by the number of successful brand in 2009 to 63 123, an increase of 95%; Sichuan market successful brand significantly increased, from 38 in 2009 to 123 in 2010, the growth rate of 224%. Such regional market demand, high consumer awareness of the industry, but also in the solar thermal around several major industrial base, China\\ s solar water heater is a major market, so many companies in the tender area in these regions as the key areas .

    Guizhou, Yunnan, Hainan, Fujian and Guangxi market, the number of successful growth in the top five brands. Among them, the Guizhou market environment suitable, low coverage, the development potential, in 2010 the number of successful brands to reach 98, and 25 in 2009 compared to a growth rate of 292%; market, followed by Yunnan, Yunnan is China\\ s development of a more market long one of the regional market, local residents for solar thermal product awareness is relatively high, and with the support of local government efforts to increase industrial development and the rise of flat products, the local industrial market has developed rapidly in recent years by the attention of many brands, 96 brands in 2010 in the sample market, compared with 2009 increased by 71 brands; in the third market of Hainan, the Hainan market for the 37 winning brands, winning only 20% of this brand market, at a low level, but the growth rate greater than the number of successful brand in 2009 increased by 270%; there in the top five markets in Fujian and Guangxi, the two provinces of successful brands, respectively, 77 and 90, growth rates were 267% and 260%.

Bottleneck leading to the development of solar water heater technology lag

[REVIEW] as a typical representative of a low carbon economy of the solar industry has become a recently concluded National "" hot topic, concern is that many traditional vacuum tube solar domestic enterprises have begun to quietly test the level of solar panels. The industry believes that, with the constant breakthroughs in key technologies, and building integrated solar domestic growing trend, was vacuum "suppressed" years of flat panel solar water heater is expected to usher in 2010, turning over the years.

    As a typical representative of low-carbon economy of the solar industry has become a recently concluded National "" hot topic, concern is that many traditional vacuum tube solar domestic enterprises have begun to quietly test the level of solar panels. The industry believes that, with the constant breakthroughs in key technologies, and building integrated solar domestic growing trend, was vacuum "suppressed" years of flat panel solar water heater is expected to usher in 2010, turning over the years.

    Technological bottleneck led to the development lag

    It is reported that in the early 1980s, Yunnan, Guangdong and some enterprises have also introduced a flat solar products of foreign technology in the domestic production for sale. However, because these products are technically flat-defective, low quality, service and keep up with the late, large number of products on this "rotten" in the roof. It is also because of antifreeze, pressure and other key technical limitations, when the flat-plate solar water heater is only suitable for areas with better use of the environment, which also caused the company stick to the southern market, the marketing concept, not product innovation, market development inner power.

    Trapped in the technical defects, quality problems and the use of time constraints and other factors, and Qinghua Sun, Temple, Emperor Ming, Li Norit, a large number of domestic solar water heater leader, are vacuum tube collector based products, which making the tube quickly captured the vast majority of domestic market share.

    Beijing Solar Energy Research Institute of the original hope was that the Yangtze River, there are two major reasons for the flat plate solar water heaters in the country left out: First, China s solar water heater, whether domestic or collective use of the system (hot water works), has been used direct heating solar collectors heat water in the traditional way, flat plate solar collectors in the water to freeze not only affects the normal operation of the collector, and the tube leading to the split up. The vacuum tube solar water heater for the winter the water in case of not emptying the basic non-frozen or not frozen (special circumstances such as snow, cold may also be frozen), so by the market. Followed by the all-glass vacuum tube water heater production costs nearly 10 years significantly reduced. All-glass vacuum tube was reduced by 5 times, more than twice the lower tank. At the same time the production of flat plate solar collectors are not much lower cost.

    Hu Guang-liang, chairman of Five Star Solar Energy Co., frankly, from the market in terms of applications and service objects, flat plate solar collectors used in large-scale projects an advantage; for household products, the domestic household products are generally direct heating, indirect heating applications small, flat-plate collector antifreeze higher prices, coupled with flat-plate in the home, the size range of options too, so the impact of the flat-plate collector on the market to promote speed.

    Key technologies to be improved

    The industry believes that, in the vacuum tube solar water heater popular, flat as a second-generation product technical defects do exist. "Over the last 10 years without significant progress, a considerable part of the product performance and quality is not satisfactory, basically still at the level of the 1980s." Engineer of Beijing Solar Energy Research Institute in Ho Chi said.

    He Zinian that although China has developed a solar water heating systems for domestic national standards and technical conditions of the 1990s, also amended the relevant conditions for flat plate solar collector technology, national standards, but with the corresponding international standard or European standard contrast , there are still a large gap.

    A home plate solar water heater business executives recognize that China flat water heater and one in the gap between the foreign absorbing coating, the second is in the control system, the third time in terms of solar efficiency.

    Industry experts point of view is more consistent, flat water heater is the biggest technical problem antifreeze, which is affecting the area north of the Yellow River, especially in cold regions of the deadly bottleneck. In this regard, Jiang Xi was said that in the region below zero winter weather conditions, be sure to use antifreeze, water, secondary heat exchanger, "European household and collective use of the system (water works) is used in antifreeze pump drive plate solar collectors and thermal storage tank to cycle heat exchanger, which can be a fundamental solution of flat plate solar collectors and collectors of water frozen freeze problem, but a fundamental solution set of flat plate solar heat the water in the scaling problem. "

    Second, to improve the flat solar collector thermal performance in efforts to solve the problem of low thermal efficiency in winter. "Effective approach is to use high performance selective coating absorber plate, to achieve high solar absorptance (90%), low infrared emission ratio (6%), but also solve the tube sheet heat exposure. Flat plate solar collectors device through the glass cover ratio should be high (90%) tempered plate glass, replace the low transmittance of ordinary window glass. "Jiang Xi was said.

    Large-scale production in contrast

    In addition to a breakthrough in flat panel technology, how like a vacuum tube mass production, reducing costs, and vigorously promote the adoption rate as civilian water heater is placed in front of flat panel solar water heater manufacturers grim topic.

    In this regard, Hu Guang-liang said in an interview: "flat panel solar industry to achieve large-scale production would require the corresponding system can achieve the same production, such as building products, serialization, standardization is the first standardized the size of solar collectors, collector plates core parts, components can be produced according to uniform standards, construction, installation, inspection should also be uniform standards, specifications, products of different brands to achieve common, can really put solar construction, installation into the universal installation of the column, not only the scale of production can be realized, but also the market will regulate the development of rational, not only to ensure effective promotion of solar energy applications, and even make solar energy popular and achieve effective integration and architecture, and promote healthy and orderly development of the solar industry. "

    As the promising prospect of flat water heater, solar shower, Aucma and other domestic brands have also invested plate solar water heater project. It is reported that Shandong Province, located in Jiaonan Haier solar water heater manufacturing plant, production lines have been adjusted, including the flat-plate collector production line, water tank foam line, pressurized spray tank production line and frame lines. "We only do solar hot water system specialists, we need to do panel of experts ." Haier said Zhou Qiang, director of solar energy planning.

    "With the introduction of national policy and the needs of the domestic market and domestic large-scale solar panel manufacturer s efforts, China s solar panel will usher in a golden age." Hu Guang-liang said optimistically.

facing real difficulties in the development of opportunities and

            China\\ s vast territory, abundant solar energy resources, the country more than two-thirds of the total area greater than 502 years, thousands of radiation J / sq m, equivalent to about 1400 kwh / square meter or 120 thousands of cards / square meter, which in theory received throughout the year per square meter of solar energy equivalent to 1400 degrees, or 12 tons of water can be heated 100 degrees Celsius. China has a large population, a total of 1.3 billion, the economy is a developing country, the rural population accounted for 75%. According to a recent survey of urban household water heater penetration rate has reached 70%. However, if the rural areas nationwide, including use of electricity or natural gas to provide hot water, its energy and economic pressures will be immense.

    China currently has 1.29 billion people, 3.5 million households, the lower the standard 60 degrees Celsius hot water per day per 100 liters of hot water temperature from cold to 45 degrees Celsius calculation, requiring a total heat Q = GCPΔT = 4500 kcal. Electricity equivalent to 5.2 degrees, equivalent to 0.5 cubic meters of natural gas. Per kWh 0.50 yuan, 1.40 yuan per cubic meter of natural gas per day, respectively, need 2.6 yuan (electric), or 0.70 yuan (natural gas). 30 days a month, respectively, and 72 yuan and 21 yuan, 864 yuan per year and 252 were needed dollars. Above are based solely on electricity and natural gas heat value calculation, not yet considered the electric water heater and gas water heaters heat transfer efficiency and its value as scaling effects will certainly continue to decline. Based on the actual survey, a household electricity water heater, the annual electricity consumption of about 1,000 yuan, the use of , its investment in 2000 to 3,000 per hour, two to three years in electricity savings can be recovered.

    If all the power to solve the domestic hot water, household needs 2 kW, the country needs 700 million kilowatts, the national installed capacity in 1999 of 2 to 2.5 times. If in ten years to solve 25% of domestic hot water supply, each year need to add 20 million kilowatts installed capacity, quite the Yangtze River Three Gorges power station project an installed capacity of more than 10 times. All domestic hot water solution with a gas, natural gas 63 billion cubic meters per year, and its pressure on resources needed to build gas pipeline investments are unbearable.

    Because of this, production and sales of solar water heater has been double-digit growth in recent years. In 2000 total sales of solar water heaters of 600 million square meters of sales income of 60 billion yuan, the total holdings of 26 million square meters, but 80% are located in cities and towns. Solar water heater in 2002 reached 10 billion yuan of output value, accounting for the national GDP, 0.1 per thousand. Currently solar water heaters and electric water heaters, gas water heater, its market share is small, but also from 5.4% in 2002 to 11.3% in 2003, doubled. Solar water heaters are expected to be rapid growth in the vast rural areas, 2005, 2010, 2015, in the national household penetration will reach 8%, 15%, 25%. Market share in the three major water heater, will soon be a \"third world\" situation. The economic benefits of solar water heaters and environmental benefits, its development has provided great opportunities.

    However, the development of solar water heaters are also facing very real difficulties. Summarized as follows:

    First, the state to promote solar thermal lack of clear policy support, especially in the industries under the jurisdiction of the current issue of the delay can not be determined, promote the use of solar energy construction standards lags behind, some of the charges around the goal of \"quality control\" increased market confusion and so on.

    Second, real estate developers of solar water heaters, apathy, and their arrangement on the indoor area, outdoor environment, level of interest in the United States compared to other issues, a serious lack of enthusiasm.

    Third, the design and planning department of the lack of a sense of responsibility to promote the application of solar and long-term considerations, urban management departments are not to be included in the management field, but also a lack of management. Although the property management department and the owners have introduced the \"Property Management Regulations\" to regulate, but let the \"Regulations\" normal operation, there will be quite some time.

    Fourth, the normal use of a solar water heater, involving host production quality, supporting quality fittings, heating element quality, water quality, water temperature meter, installation quality, and service to honor these commitments to ensure that the six issues, the current market mechanism in the absence of management in this area, the installation of a solar water heater is often not convenient to the user, but a lot of trouble.

    Fifth, more and more compressed urban high-rise building solar water heater market, but can not ask the city\\ s long-awaited \"balcony\" type solar water heater, is bound to its own with the construction and the combination of a higher thermal efficiency requirements .

    Sixth, the price of solar water heaters, although a huge difference between different brands) are often more than double), but has been declining in recent years, and may have further to fall. Here there are of course the reason there is a big profit margins, but rapidly shrinking profits although it may encourage technological progress, but also often cause producers to give up some quality goals, to the detriment of the interests of consumers has also brought negative impact on the market.

    Seven, due to the vast rural areas of dispersion, the solar water heater \"free\" to make a higher demand. Of course, since the majority of farmers is still low level of the overall economy, but also how to reduce the cost of solar water heaters made new demands.

    Eight, have mushroomed rapidly increase and OEM \"brandable\" mode, what will the market for solar water heaters, what kind of results, is still difficult to predict.

Indicate the selection of solar water heaters in the country issued in March

    According to the China Association for Quality Promotion survey, nearly Qicheng solar water heaters in winter there are security risks, more than 50% of the solar water heater can not meet consumer demand, consumer dissatisfaction focused on the water heater easy to freeze plugging, leakage, and poor collection efficiency, caused an important factor in these problems is water heater material shoddy.

    However, this situation will be standardized and improved. National Standardization Technical Committee Secretary-General Jia Tieying Solar today in an interview that "the main components of domestic solar hot water system selection of general technical conditions" has the approval and is expected to formally promulgated in March next year.

    It is reported that China s annual production of solar water heaters 23 million square meters, annual production of more than 76% of the world. However, the selection of the main components has been no uniform national standards, resulting in mixed selection of solar water heaters, some manufacturers do not provide consumers with rigorous testing of piping and fittings, a large number of risk products into the market.

    China s solar thermal Committee Luo Zhentao that must be guaranteed by the material life of the product specification, reliability and stability. By the China Institute of Standardization and Wong Ming Group jointly drafted the "domestic solar hot water system selection of the main components of general technical conditions" through the validation, not only safeguard the interests of consumers, but also enhance the technological level of the solar industry, and promote the industry healthy development.

    Jia Tieying said, according to national planning, the next two years will have 15 thermal aspects of the national standards, including spare parts, technical and engineering aspects of solar water heating systems will be gradually developed, introduced. Currently, the National Standardization Committee and other agencies are developing solar water heater "limits and evaluation of energy efficiency rating" mandatory national standards.

How can a anxiety lightning protection

[REVIEW] Recently, the municipal meteorological bureau director Yang Hongming lightning led scientists to the countryside publicity lightning weather knowledge, we found that some residents in rural areas housing the city\\ s roof installed , water heaters due to the lack of these mine facilities, a move Ray\\ s problems.

      At present, solar water heaters strokes occurred in 4 cases mine incident

Recently, the Municipal Bureau of Meteorology weather mine director Yang Hongming led scientists to the countryside publicity lightning knowledge, we found that some residents in rural areas housing the city\\ s roof installed solar water heaters, water heaters due to the lack of these mine facilities, a move the hidden mine .

\"The city estimates more than 5,000 solar water heaters, and some are also installed in the school dormitory roof. Water heater installed in the roof, with a security risk, appealed to residents to promote mine awareness, mine water heater initiative to do the work without the required placement of anti- mine facilities, in accordance with relevant provisions of the law enforcement agencies can weather more than 500 yuan imposed a fine of 30,000 yuan. \"

5,000 solar water heaters move the status quo Ray

Recently, Yang Hongming housing area to a small village Lotus Township inspection mine work, we found the village several solar water heaters.

Summer is high season for thunderstorms, but the city is more than mine. This is mainly due to erosion of the hilly landscape is Suining, hilly, Gully aspect, to spread all over the canal, the middle of the low-lying four-week high, coupled with the outer edge of the subtropical high in summer climate, abundant water vapor, so prone to lightning phenomenon. The solar water heaters are generally placed in the roof, if the anxiety of mine facilities, are more vulnerable to lightning.

\"Solar water heaters, metal structures are more common with electric heating, and roof installation location is generally higher than the height of lightning rod and lightning protection zone, in the absence of effective lightning protection measures, it is easy to become a lightning target. Ranging from water heater explosion destroyed, while in direct electrical injury were the survey shows that since April this year, within the city there were 963 times the number of lightning, thunder and lightning intensity of 57.6KA. \"Yang said. \"According to preliminary estimates, the city\\ s rural areas are currently about 5,000 various types of roof water heaters, water heaters being struck by lightning cases have occurred as of now, the city, there were four events from the water heater lead mine.\"

Dealers that sell water heaters do not need lightning protection

Not long ago, as a consumer reporter came to City a solar water heater sales store and see the huge store on display at forty-five kinds of brands of solar water heaters. Boss said: \"Last year we sold more than 500, are not safe lightning protection, we use the water heater you though, no problem, because there is no sharp part of the water heater.\" Vendor of mine work on solar water heaters so indifferent, Reporters are very worried.

Product safety requirements by country, solar water heaters to be installed lightning protection facilities, and its products also have the instructions to install lightning protection facilities, notes, general dealer has failed to install, is the disregard for life and property safety of consumers.

According to reports, if mine own solar water heater deal, first distance away from the installation of water heater 3 m 1.5 m above the water heater at the top of the lightning rod, and do protect against lightning; Secondly, from the roof the introduction of solar water heater indoor power lines, signal lines, water pipes should be metal shielding; Finally, you should install leakage protection switch back-end SPD (surge protector), and do protect against lightning and the lightning induced wave intrusion.

According to statistics, Suining average number of lightning strikes up to 30 days to record up to 60 days, is more than mine. Farmers mine awareness weak, so the solar water heater installed lightning protection for these facilities is a priority. It is understood that the wall below the floor construction of solar water heater, do not worry about summer lightning problems.

Focus is to prevent an extension of flammable and explosive places

At 14:40 on August 30, 2007 about the British soaked village of Carp River County Chi Yang Hui 10 group home struck by lightning, 12-year-old student died on the spot. According to the survey, the day of the accident, lightning is the summer period, Yang Hui was at home watching TV, suddenly found TV outlet in the sparkle, immediately went to pull the plug, and instantly a strong line of lightning current through the light spot to Yang Hui fatal. According to the survey, Yang Hui\\ s family was then struck by lightning off in the area, building on top of the CCTV line lightning protection measures are not taken; Second, the overhead wires from the house side of the house too close (less than 3 meters), hundreds of thousands of volts of lightning voltage the formation of lightning counter-attack; Furthermore, the whole house is not installed lightning protection devices, power line installation is extremely irregular.

At 3:35 on August 16, 2009, Berlin Township, the village housing area Lotus group 3 a lightning accident occurred, the lightning causing Wang Chenghai residential building and the surrounding villagers were Jihuai appliances, resulting in total direct economic losses of 3.8 million. The same reason lightning lightning lightning protection devices are not installed, the roof water heater is not connected to potential measures, overhead power supply, signal line lightning protection measures are not taken.

\"Mine detection involves various sectors and systems, with emphasis on flammable and explosive places, schools, hospitals, financial institutions, construction projects and enterprises, institutions, but some units did not take the initiative to submit applications for mine safety inspection, or only a partial test. Overall, the city\\ s annual inspection of lightning protection device surface is still relatively narrow, some units can not attract enough attention, as part of the communications sector and individual enterprises, institutions, and every year its been due to lightning The loss is not small. Furthermore, is part of the construction project will be construction of lightning protection devices are not reviewed construction, after completion of the project did not pass acceptance testing will be completed and put into use in rural areas, urban building rooftop solar water heaters and other electrical devices generally do not take lightning protection measures which are very security risks. \"Yang said.

? Links

Occurrence of lightning in the atmosphere of intense discharge phenomenon, usually in a thundercloud (cumulonimbus) has happened. Lightning can be divided according to their location of occurrence of lightning within the cloud, inter-cloud lightning, cloud-air lightning and cloud-ground lightning. Cloud to ground lightning discharge is formed when the intense thermal effects, electrical effects, mechanical effects and electromagnetic effects, can be very destructive, the production of people\\ s lives and safety of a larger threat.

Most vulnerable to lightning strikes in life objects are the building angle, roof, eaves, gables, parapet; building on the exhaust, the exhaust pipe; a subsidiary of metal buildings, such as solar water heaters, etc.; tall tree; Square, playgrounds and other places of the flag; transmission and distribution lines and towers, radio tower, communication base stations, billboards and other large metal objects tall.

can battle one roof to share?

[REVIEW] According to Harbin, housing security and Housing Authority property at Chen introduced, according to the \"Property Management Regulations\" and \"property law\" the relevant provisions, the roof is a common site, the owners do not allow unauthorized possession. Based on the actual situation, residents to install s must obtain residential property owners\\ committee and the top-level owner\\ s consent to install.

      Battle of illegal installation of roof

According to Harbin, housing security and Chen introduced at the Housing Authority property, according to \"Property Management Regulations\" and \"property law\" the relevant provisions, the roof is a common site, the owners do not allow unauthorized possession. Based on the actual situation, residents to install solar water heaters must obtain residential property owners\\ committee and the top-level owner\\ s consent to install.

According to introduction, part of the district and the old Harbin residents on the top floor installation of solar water heaters, and many property owners without the consent of the installation of solar water heaters produced by violations of contradictions. Top-level residents are worried that, once the equipment leaks, home suffer. Comments on behalf of the property North Pine Eagle property residential green water, said deputy general manager Liu branch, without the consent of the property agreed to the installation of solar water heater problems borne by the factory owners, but also three dozen property line. Zhang Xuan West residential property company, said the roof more than one water heater, increasing the body\\ s load-bearing floor, really unsafe.

      Three of the more obvious advantages

      Electric water heater, a solar water heater with a focus on the whole building to use solar water heaters more, what more advantage?

      According to the City relevant staff at the EPA Science and Technology Lee introduced, electric water heater more than 2,000 yuan each, according to electricity, each household to be hundreds of dollars on electricity. Install a solar water heater family spend an average of 3,000 yuan, although no power to spend money but take public space. Families do not have solar water heaters, the need to let go of the pipe in the water, drain again, Sheung Shui, it also brings water to waste. Winter ice is also prone to wandering child phenomenon, caused by safety problems. Concentration of a building using solar energy, simply install the collector unified, up and down the tank, circulating tubes and other devices, solar water heaters save energy through intelligent control system, the Four Seasons is building hundreds of households to provide hot water, saving space do not spend tariff, just take water. A number of manufacturers currently on the market are doing the project, a residential building, installation costs in the million or so, share the home as long as a few hundred dollars, and affordable.

      Step by step solution on demand

      Whole building energy-saving environmental protection, install a solar water heater can promote in Harbin? According to the City Housing Authority housing security and Publicity Minister of the Ministry, at present, Harbin is not the introduction of relevant laws and regulations to guide people in residential buildings to install solar water heaters. Currently more than 4,000 communities in Harbin City, the original, mostly flat roof, there is no stop light problem, if a residential building space for the installation of a solar water heater is not a problem, but the need for owners and property agreement.

      Some older residential buildings, the top leaking through the cold more serious, now in progress and some energy-saving residential buildings, the flat roof into a pitched roof, the owner may request the construction side, self-financing the installation of a water heater, and the design the trend line for the whole building to provide hot water. New residential developers to plan ahead, set aside real estate construction pipeline, the houses when home buyers to seek consent, unified installation of solar water heaters, the installation costs into the housing fund in the count, step by step to solve the problem. According to Minister on, the residents of Harbin City, the feasibility of building a larger concentration of solar energy, but has yet to have a building to install a solar water heater precedent.

      Heilongjiang Provincial People\\ s Congress Hou tree was proposed, housing, environmental protection, energy conservation department may be feasible to come up with specific implementation plan, according to public needs, providing technical guidance.

Analysis of the spatial extent of technological innovation of

[REVIEW] \"from the current market competition and corporate performance, our products, is much room for technological innovation: First, on the other major components in the vacuum tube technology upgrade; the second is in the product structure and function innovation; third is in the solar-based, such as auxiliary power on the creation of new products. \"

     \"From the current market competition and corporate performance, China\\ s solar water heater products is much room for technological innovation: First, on the other major components in the vacuum tube technology upgrade; the second is in the product structure and function of the innovation; three in solar-based, auxiliary power and other new products on the creation. \"

      Recently, China\\ s solar industry experienced technical experts, Beijing New Energy and Renewable Energy Association, vice chairman of the Lessons of expression.

      Lessons also pointed out that in the solar water heater product innovation and upgrading process, the large enterprises to play an exemplary role, to develop innovative product technology roadmap for internal planning and research and development each year to ensure that the enterprise product technology R & D and innovation for the cost of the proportion of investment.

      It is understood that since last year, the first in four seasons Mu-song within the industry launched the \"automatic\" water heater, and then have led to Sang Le, Huang Ming, Sun Yu, Qinghua Sun, brilliance and other companies quickly followed up the introduction of digital technology, New 3G units and other automatic solar, solar water heaters in the domestic market quickly set off a wave of \"automatic\" product competition boom.

      In this regard, Lessons that the current domestic enterprises in the intelligent instrument controller and overall system control technology, water has been very mature, especially the stability of some industrial components has been significantly improved. The emergence of automatic solar water heater will help market the application to facilitate the consumer\\ s use. The future, automatic solar water heater can be used in addition to ordinary families, will be widely used in large-scale construction and water engineering. Especially in the hot water system for remote operation of control, the automatic water heater will be more advantage of smart technology.

      Chen Gang, deputy secretary general of China Household Electrical Appliances Association, believes that solar water heater with automatic means of technological innovation, the market will not only existing \"manual, semi-automatic solar energy\" to achieve the upgrading of the main town in the country and took the lead off a new round of rural areas market consumption boom, will promote solar water heaters as well as from rural to urban areas such as the future among the large building, which greatly expand the industry\\ s development. Can be expected to \"intelligent digital control, system integration design\" as the core of the \"automatic solar energy\" will be the development of the industry trends.

      Lessons also that, after the product is the key to solar water heaters and heat-absorbing properties of thermal protection in two areas, but the emergence of automatic solar energy, will be based on the original technology into the business of intelligent control technology, a unique, high-tech content of representative products.

      In addition to water heater whole system of technological innovation, Lessons also noted that in all parts of the vacuum tube that is also a great innovation. Currently on the market can only offer these low-temperature glass of water, and in the technical means can produce a \"family can drink the water temperature of 100 degrees\" and the \"printing and dyeing factories in the warm water of 150-200 degrees . \"

      In the product R & D and innovation, Lessons that enterprises should focus segments to local conditions, characteristics of different regions of the light appearance of functional design and development of different products, so as to truly meet market and consumer demand.
