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.

Solar water heaters look forward to short-listed home appliance trade

Indicate the selection of 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 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 s 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.

Solar water heater into a new large farm children are keen

With the country in May this year be included in plan home appliances, solar water heaters for many rural families are keen to acquire \"new large child.\" According to the National Statistics home appliances, to September, for example, the national water heater sales totaled 142,800 units, total sales amounted to nearly $ 300 million. Sales of the top ten in the water heater manufacturers in the countryside, eight are pure , many in the urban market is quite hot water heater brands and fallen off because there is no solar energy products.

? growth of solar water heaters

Much higher than other home appliances category

Data show that in May this year, solar water heaters are included in the formal areas of home appliances, sales are showing rapid growth, the growth rate is much higher than other home appliances category. August sales of which increased 1.28 times compared with July, August, September, and over increased by 51%. September this year, the countryside water heater in a single month sales reached almost the first seven months this year, twice the total sales, which the majority of them come from solar water heaters. Water heaters in the countryside in September the top ten best-selling brands in all eight .

\"And the urban market very different, water heater sales in rural areas is completely reversed!\" A well-known person in charge of sales of gas water heater manufacturers mentioned, almost unable to move the market in the city\\ s solar water heaters currently in the rural market accounts for the absolute mainstream. He mentioned, as gas water heaters require gas and other municipal facilities construction, so in most rural areas can not promote. Although some manufacturers have also introduced the use of liquefied petroleum gas tank gas water heater, but the sales results are not good. For electric water heaters, the sales situation in rural areas, although better than the burning heat, but with far less solar energy products in a horizontal line.

? Use low-cost

Tempting for farmers

Use of low cost solar water heater in the rural market is large sought after another reason. Relative to the gas water heater and electric water heater, the solar energy although a larger initial investment, but the basic one-time investment in the future will not have to use gas costs or the cost of electricity, etc., which the farmers are very tempting. \"Although the and heating fuel prices are expensive, but the state policy of home appliances is based 13% of total product price subsidies, which makes enjoy the benefits of solar water heaters is the biggest but to promote the sales of fast up! \"insiders, in some moderately well-off rural areas, solar water heaters have become the new layout of new houses that people must get married\" a large child. \"

? China\\ s solar water heater

Output accounted for 76% of the world

But some industry insiders point out that solar hot water heater in the rural market but its lack of national standards related to the shortcomings more apparent. It is understood that the present annual output of solar water heaters 23 million square meters, annual production of more than 76% of the world. But now the main components in the solar water heater is not even on the selection of uniform national standards, lead to some adverse selection, with the risk of product into the market. In addition, solar water heater parts, installation and so there is no national standard, so this is by bringing home appliances products in the rural areas the prevalence of large deletions in the country is actually the subject of the free state. No wonder some companies pointed out that \"in the absence of national standards to rush to the countryside, may be harming consumers and the solar water heater industry!\"

Overcapacity in the industry spread to the solar water heater

Overcapacity in the industry spread to the

     As a sunrise industry of solar water heater industry has recently experienced growing pains, while the rapid increase in the number of newly opened businesses, a large number of vacuum tube production line horse; the other side of the market response is lukewarm. According to City Solar Energy Industry Association\\ s statistics, this year, the city opened a new solar water heater business and supporting more than 200 enterprises, however, into September, the city\\ s solar water heater business sales dropped sharply, the chain fell about 50% .
    For a time, \"excess capacity of ,\" the thesis for entrepreneurs suddenly nervous tension. In the end is excess capacity or industry to enter a period of adjustment? How to prevent a sunrise industry ups and downs?
    Ten years there has never been a dip
    Even in last year\\ s financial crisis, the city\\ s solar water heater business sales still produce a nice \"report.\" In 2008, the 120 million units in sales of solar thermal products, representing an increase of 30% in 2007.
    In the first half, sales of solar water heaters in our city also maintained a rapid growth, especially into the second half since September, but suddenly a sales decline, sales in September than in August fell 50 percent.
    \"This phenomenon has affected almost all the solar water heater business in our city, is 10 years, never had!\" City Solar Energy Industry Association, Xu Zhu Ling told reporters that even as big companies such as Le Sang, also in October sales In the fall, some of the sales team did not even small business sales fell by 2 / 3.
    Home appliances, \"a good hard song to sing.\"
    With traditional electricity, gas water heater, solar water heaters more energy efficient, should be more likely to be the rural consumer acceptance, but also enjoy the state at time of purchase 13% of home appliances to financial subsidies. Therefore, many in the country launched the beginning of home appliances, to his great expectations. However, with the advance of home appliances, factory surprised to find that neither the policy of home appliances to make their products are selling, do not let their own brands in the short term access to rural consumers.
    Last month, the reporter arrived at the sea salt wash pump port industrial zone, Zhejiang New Energy Co., Le high, the enterprise was a lively scene. Successful solar home appliances brand so high music sales soared in August, the company sold nearly 3,000 solar water heaters. When the company responsible for the market is still very optimistic. However, again contact the reporter yesterday, the company responsible person, but the news has been quite pessimistic in September the company\\ s chain of solar water heater sales dropped by nearly half. \"The market is weak, consumers are still waiting to see, it seems to bring home appliances is not obvious.\" The official said.
    For the city\\ s many successful home appliances, solar water heater companies, are facing tough choices. Forward in the face of unpredictable market also continue to invest in manpower, material and financial resources for publicity and promotion; back, pre-made home appliances for all the efforts will be wasted.
    Herd caused confusion in the industry
    Reporters learned that last year\\ s solar water heater manufacturers Jiaxing 890, this year has increased to more than 1,100. \"A lot of formerly engaged in the textile, metal and other industries, the boss, under the influence of the financial crisis to switch to solar water heater industry, while a large number of family-owned small businesses are also entered, the low level of repeat expansion and investment, resulting in confusion in the industry . \"Xu Zhu Ling said.
    The vacuum tube manufacturers, for example, the original vacuum tube Jiaxing only 330 production line, to the end of this year will increase to more than 700, supporting the production of solar water heaters can be 10 million units. \"National sales of solar water heaters a year for 40 million units, the vacuum tube Jiaxing market share to reach 1 / 4 is still very difficult, so many companies in September tube inventories to several million units.
Industrial clusters or face shuffle
    Held in the afternoon before the situation analysis at the solar industry, solar energy, Zhejiang digital music Sang Ltd, who Geng just do not agree with \"excess capacity\" with that, \"China\\ s solar water heater penetration is still relatively low, or very large market potential and, therefore, should only be a current industry adjustment period. \"
    However, how to prevent this sunrise industry ups and downs? An industry source admitted that five people can manufacture solar water heaters, 300 people can do. Some small businesses, selling only a few thousand sets of products a year, the same can survive. At present, solar thermal industry has a number of firms is several times the number of firms in other industries. If the solar thermal industry leader in the short term can not increase barriers to entry, reach-scale expansion, fail to realize the industry reshuffle and enterprise integration, some unqualified enterprises eliminated, then the piece of the solar thermal industry not mature, \"cake\" competition will appear more chaotic situation.
    Inner strength, build sales networks, to grasp the end, to achieve the transformation and upgrading, which is Xu Zhu Ling\\ s recommendations. It is reported that companies in the solar energy industry cluster in Jiaxing, there have been a large amount of money to purchase a number of investment and production testing equipment, automatic production line of business update.

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.

Who tube solar water heaters life?

Who \\ s life?

[REVIEW] solar water heater short-lived problem, solar energy market is currently the most common and worrying phenomenon. Some small-scale , there is no high-end industry equipment, superb technical expertise not only form a small assembly workshop, under the banner name of sorts, with \"regular\" playing the price war.

Recently, there have been two gentlemen came to a solar energy Co., Ltd., said to re-purchase of , and asked their purchase reason, get four points is difficult to believe but have to answer the letter. First, install a solar energy was more than a year, in particular, sunny weather, the sun one day, not how hot the water; the second, as long as the encounter cloudy or rainy days, even if only one day, put out the equivalent of room temperature water the water; third, stand on the verge of collapse before long, they do not want the victim way reinforcement is not assured continued use; fourth, tank manufacturers do not like can be used as promised 15 years, it took two or three years on leakage phenomenon.

Short-lived solar water heater problems, it is the current solar market, the most common and worrying phenomenon. Some small-scale solar water heater manufacturers, there is no high-end industry equipment, superb technical expertise not only form a small assembly workshop, under the banner name of sorts, with \"regular\" playing the price war.

The most fundamental flaw of these products on the life issues, and some can be used two or three years, some only a few months, there will be a variety of conditions, solar water heater caused a \"short-lived ghost\" is the direct cause There are four key points:

First, the bracket process rough. Solar water heaters stent selection and structural design and installation requirements are very high, professional design and installation of solar energy and protect the life of hard infrastructure.

Some small businesses do not stand a professional production equipment and paint techniques, combined with four recruitment of migrant workers formed the \"Install guerrillas\", both of these installers do not understand the design of piping, water heaters, the main fixed and other professional knowledge, but do not know a post of maintenance, resulting in problems abound. For example, the mounting bracket for fixed water heater parts, big brands use more steel bar, strong, corrosion-resistant, but some manufacturers are using wire fixed, resulting in some areas when confronted with heavy rain, hail and other inclement weather, there are many Solar water heaters will naturally shaky, even crashing to the ground.

Second, poor insulation. Solar water heaters produce hot water during the day and stored in a storage box, if the insulating layer of thermal insulation performance is not good, overnight, rainy days can not be used, or difficult to use. Solar water heater insulation resulting in poor performance is largely due to water heaters, insulation, insulation of hot water temperature determines the quality level and the amount of hot water. Good insulation layer using imported raw materials, such as polyurethane, low thermal conductivity, high temperature; high temperature insulation technology using automatic quantitative foaming, and high temperature aging treatment, lasting and stable high performance insulation.

Some poor materials, high thermal conductivity, foam is not uniform, night temperatures can drop more than ten degrees, rainy days experienced no hot water. Some black-hearted enterprise, in order to reduce costs, even using homemade benzene board, insulation effect plummeted a few months later, in 2012, after almost no insulation.

Third, poor liner selection. Most solar water heater manufacturers have said that the water tank is stainless steel. Also stainless steel, but chromium and nickel in stainless steel are very different.

Good solar water heater using high chromium high nickel stainless steel food grade liner, liner ensures durability, corrosion resistance and strong; inferior to use more low-grade stainless steel liner, the basic nickel-free, corrosion-resistant performance is poor, life is short .

Fourth, vacuum workmanship. Vacuum tube solar water heater core components, solar water heater is the \"heart.\" It directly determines the quality of the entire water heater performance. Performance by the use of vacuum coating technology and cleaning, coating, vacuum, seal and other processes and so on.

According to the Sun Co. researcher, some small business or a small workshop, there is not enough money to put into the tube advanced production equipment, but in order to survive, had to use the most original, most affordable tube. Such a low degree of vacuum tubes, high-quality products only 1 / 100, while the tube a lot of residual impurities and water vapor, in the face becomes hot gas, vacuum reduction. In low vacuum coating stability is poor, the intimal layer on two or three years of aging, loss, leading to a sharp attenuation of collector performance, can not absorb enough heat.

How to solve a series of fundamental impact on the life of the solar water heater problem?

First, governments at all levels to increase policy support for solar energy industry. Although China has long adopted a \"Renewable Energy Law\" and the Implementing Rules and other legal documents, but compared to Spain, Germany and other Western countries, mandatory energy-saving measures, the government promote the use of solar energy and not enough supervision, some high-end products efforts to promote the application is lacking.

Second, the solar industry to strengthen self-discipline. Advanced production equipment and high-end technologies that not all companies can have the strength to go into research and development. Throughout the region around the solar energy distribution, brand-name product has a huge market, they will be low cost, low-quality products to market rough, seriously affected the industry\\ s healthy development. According to incomplete statistics, the market has nearly 300 million units around the solar water heater products are not quality and maintenance support. Low-quality solar water heater to the bad impression left by the consumer impact of the industry\\ s image, it also hinders the healthy development of the solar industry pace.

Third, the use of positive publicity to strengthen the awareness of consumer acceptance. Most consumers choose only by the appearance of solar water heaters, solar water heater which one is better production techniques and products there is no clear understanding. The most unscrupulous manufacturers is to increase the publicity of the conceptual tube, and \"three-cavity tube\", \"three super-pipe\", \"Sanxin pipe\", \"purple pipe\", \"space control\" and other terms fly, a serious disrupt the concept of consumer choice, resulting in consumer products can not be a dispassionate look at the nature.

To this end we call on all kinds of manufacturers to fundamentally solve the problem of weak products with the highest quality products hit the market, all levels of government, the solar industry management organizations should take positive measures as soon as possible to integrate solar energy throughout the production of resources, so that \" short-lived ghost \"solar water heater as soon as possible,\" retired \", so as soon as possible onto the solar energy industry standardization, so that the whole of China and the world\\ s people are fully trust and use of solar energy facilities.
