Solar water heater caught in stagflation rural market

In 2010, solar water heater industry has continuously to exceed 35% of the market growth rate of nearly 5 years, so the speed gave many traditional industries surprised. Especially in 2009, the first round of home appliances in rural market will be detonated, when comparing the market surged nearly 50% in 2008. Compared to the previous 5-year growth rate in 2010, significantly slow down the pace, the annual growth rate of 15.7%. And 1 May 2011, the industry\\ s overall growth rate of less than 10%, the industry growth rate to fall further. Solar water heater industry experienced a sprout, grow, after the outbreak of good Love, return to the rational growth of the industry, the level of the slowdown is an indisputable fact.

Data show that 70% of the sales of solar water heaters from the rural areas, while the strong support of solar water heater industry, the growth rate in the hustle and bustle of rural markets, the rural market slowdown, trapped in stagflation. We look at a line drawing of the market:

Since January 2011, Jiangsu, Anhui, Hunan, Hubei, Jiangxi, Henan and other places subject to drought, rainfall for the past 50 years minimum. \"Solar water heaters currently the main market in rural areas, due to the impact of drought, most farmers concentrate on a major drought, the town\\ s promotional activities for the much less popular.\" Mu-song Seasons Solar Hubei official said.

March 2011, \"drought and solar water heater itself is a contradiction.\" \"Drinking water have become a big problem, who would consider buying solar water heater bath?\" Anhui, an operating solar heaters dealers ask the author.

March 2011, Zhenjiang, Jiangsu Province, a business brand water heater solar heaters dealers told the author, \"in 2005, left rear, I would be able to sell four to five year product units in 2009, only 200 units sold, and By 2010 sales of more bad, and we sold a total of 40 sets of goods in 2010 than in 2009, sales fell 30% over the same period, and this year has yet to see any signs of recovery. \"

May 2011, a brand of Jiangsu Yixing solar solar dealers said quite some resentment, \"another two months, I will not sell solar energy has diverted.\"

May 2011, consumption of solar water heaters in the traditional province of Henan, a brand to town as the center of continuous promotion in a down town promotion, marketing staff commentary was thirsty, but in the end is often a sales victories one or two.

May 2011, Linyi, Shandong village to do some promotional activities, brand marketing officer, said, \"This year\\ s event is very lively, a lot of people watching, but not many people pay.\"

June 2011, the Yangtze River region of strong precipitation, Jiangxi, Hunan, Guizhou, Zhejiang and other places down heavy rain, drought relief in the case once and again, Sharp droughts, floods in some regions, \" half of the wind, no rain falls in the rainy day, end-market promotional activities are ordered a halt to solar, solar installation should be stopped, of course, affect sales. \"Zhejiang region of a solar energy company CEOs said.

Outlined a series of line drawing solar water heater market in rural areas suffering a setback in real truth. In this regard, the industry that in 2009, feast of home appliances overdraft spending power of the market for many years, the rural market is becoming saturated state, coupled with domestic economic uncertainty, CPI is high, fell to a record low consumer willingness to , and consumer spending will reduce the lack of capacity to a certain extent affected the rural market shipping terminal. Stagflation in the context of the rural market, on the one hand, will lead the industry reshuffle; the other hand, will promote solar water heaters to solar energy companies from the to the use of solar energy in the high temperature phase of the solar boiler, and even solar solar thermal power generation and more areas of development, but under the pressure in the rural market will also increase the solar energy companies to enter the urban market and overseas market power.

A general increase in export price of

    Earlier this year the end of the 109th Canton Fair, due to raw material prices, labor costs and other multiple factors, the general rise in prices of export products. The products as clean, safe, and efficient energy, despite a number of foreign customers, has won a lot of orders, but the huge cost pressure, solar energy companies can only follow the market. Recently, the company learned from a number of solar energy, solar water heater export prices increased by 10% to 15%.

    Export of solar water heaters in general price increase of 10% to 15%

    Raw material prices, rising labor costs, RMB appreciation, each related to the overseas export of all solar energy companies will be faced with the \"three high\" tremendous pressure.

    The first is the continuing rise in raw material costs. It is noted that the lowest blank tube from last year when 2,400 yuan / ton up to the end of March 3500 yuan / ton, or up to 45%. Solar water heater foam material (commonly known as black and white material) from 13,000 last year, the lowest / ton up to 18,000 yuan / ton, an increase of 38%. 304 stainless steel commonly used by 20,000 yuan per ton last year, the lowest price to 23,500 yuan / ton, or more than 17%. At the same time, frame, meter and other accessories prices were different ranges of prices.

    From the understanding of the situation, the central parity of RMB against the U.S. dollar reported 6.49, which means that the main settlement currency in U.S. dollars of solar thermal products in export profit margins will be further compressed. Coupled with rising labor costs, even if the solar energy products have 17% of national export tax subsidies, but in the solar house, apparently unable to digest the enormous cost pressure, therefore, the price of export products has become the trend.

    It is reported, including Norit, Wuxi Central special, Bedford Wright, Changzhou Sheng, including the number of overseas export business in the performance of the more active enterprise, its exports have different levels of price increase, price increase in 10% to 15%. In this regard, special Solar Technology Co., Ltd. Wuxi ring, said Chairman Jiang Zhongwei, soaring raw materials, RMB appreciation of the environment, solar energy companies export only through price increases to ease the pressure; Bedford Wright stakeholders also said that this year the company has export prices increased by 10%. Even more complete industrial chain corresponding Norit raised prices of export products.

    The general manager of Mei Jianzhong Sheng told reporters solar, filled to the pricing of solar energy in the main export products to the RMB exchange rate as a reference standard, adopted a relatively flexible approach, in general, customers can understand and accept.

    Export volume of business affected to some extent

    According to public information, in 2010 the export of solar thermal products are mainly exported to South Africa, Mexico, Turkey, Germany, the United States, India and other places. As countries for the development of solar energy on behalf of the new emphasis green intensity, have introduced the corresponding incentives and financial subsidies, China\\ s solar thermal products in the market still has a strong export potential and competitiveness.

    However, with this year, a sharp increase in domestic solar business cost pressures, many companies involved in export business has been affected to varying degrees. Mei Jianzhong pointed out that the current adverse environment, the export business for more customers or rely on long-term cooperation, but efforts to develop new customers obviously feel better than ever.

in question who is intelligent machines?

If there is a can be sorted out, like mobile phones will support a variety of functions, users only need to be selective according to their needs installation, I believe this time you will not have hesitated for a bar. The problem is solar water heater can be as smart phones such as human machine do?

A question to you, if you have 5000 yuan budget, what would you consider mobile phone? I believe most people the answer will be given the word – \"Apple\", Apple now has spread to the effect of high school, and the consequences worth considering. Deep down and then ask you a question, why so popular Apple iPhone4 is to follow suit? Or do you really know Apple? Do not know how many friends can say two. The Android system relative to the field, the emergence of dual-core smartphone, but also bring us more options. Control of the game experience or whether it is entertainment, Apple iPhone4 to meet, and meet the same dual-core smartphone. This made people understand that love the iPhone4, Apple is not the only option for purchase, from a functional point of view, it is an intelligent choice, unless you have a soft spot for Apple\\ s brand.

Then came the second question, if you have 3000 yuan budget, what would you consider solar water heater? I believe this time the eyes of each person has their own answer, because each person has different standards to choose. Selective absorber efficient, selective thermal performance and strong security, digital selective, selective energy-efficient … if you need one of two functions how to do? Do you also buy two? Believe that few consumers will do this, more people are for some trade-offs, forced to give up one of them.

If there is a solar water heater can be sorted out, like mobile phones will support a variety of functions, users only need to be selective according to their needs installation, I believe this time you will not have hesitated for a bar. The problem is solar water heater can be as smart phones such as human machine do?

\"Smart machine\" there is the need

In fact, in terms of solar water heaters, practical, easy to use product is the consumer\\ s first choice because it can not show to other people carry around anywhere, even in their own homes also do not see the machine is basically a way of , so use feelings is the most important. So respect the feelings and needs of users, an optional feature available to users of solar energy intelligent machine concept has entered the industry. Proposed the concept of time is just a theory, but with China\\ s solar thermal technology, the prototype of the smart machine or a single function began, he was able to keep the heat, digital, and a key control, energy-efficient various types of solar energy into the market, also has been a demand of consumers, so can support a variety of functions, according to consumer demand for selective installation of solar intelligent machine is ready to come out.

In the survey found that many enterprises are an advanced feature as a selling point to give the products, to implement different price points and grades of products to enrich its product line to enhance their market competitiveness, and thus also to consumer those who have lost the opportunity to round the product, or can not face the problem of choice.

In 2011, Beijing Yu Xin Solar Energy Industry Co., Ltd. of foreign claims, the first solar water heater \"smart machine\" R & D success, and promote the market. The news caused widespread industry and consumer concerns. Subsequently, the Xin Yu Sun will be \"intelligent machine\" into the terminal, solar water heater \"smart machine\" ushered in a test. Many industry experts said that \"the product will become a touchstone, if gained market recognition, it will be possible to bring the solar thermal industry a new standard and change.\"

Scale on a regular basis is important to clear

    Hot days, and gradually increase the frequency of use, along with some of the problems can also enable the public to worry about endless. Recently, the area who lives overseas Greentown area Jianxi Ms. Yang and Ms. Wang said, his home water heater, Sheung Shui, time is getting short, a smaller amount of water, the water does not look clean, it is Editor\\ s Note ?

Clean out a lot of scale

Reporters follow a solar water heater repair company managers and Master Huang Ping Yingjie to go see. Feng Yingjie in the roof, after some checking, smiled and said: \"The solar water heater in your house \\ bath\\ it!\"

Water heaters as well as \"bath\"? Ms. Yang, Wang revealed the surprising look.

Master Huang smiled and said nothing. I saw one by one, he carefully put down the vacuum tube removed, the inside of the water poured out, and washed repeatedly with water. Glass cleaned, turn the water tank. Fengjing Li and yellow together to hold the master tank, so rocking back and forth, inside the water from the nozzle flow. This reporter saw tanks from inside the glass tube and the water muddy bear out, mingled with large scale.

Finally, clear out a full scale can hold more than half of washbasin. \"Is the scale occupied the position of the tank, water tank filled with water less, and sometimes not on the full.\" Master Huang said. Slowly, over clear scale, the water inside the tank has become clear the.

Usually have to wash with 3 years

How is there so much water heater inside the scale it?

Feng Yingjie has been engaged in solar water heater repair five years, he said, the water is relatively hard Luoyang (the city\\ s main drinking water is groundwater, mineral content), a long time, the natural scale inside the tank piled up. Scale than the two things occur:

First, plug the vent. Feng Yingjie said vent in the bottom or top of the tank, the role is to balance the pressure difference between inside and outside the tank, once blocked, the internal heat can not be discharged, will be increasing pressure, the tank will be broken up. \"For almost a tank around $ 600, better and more expensive, we replaced this year has given dozens of tanks up.\" Ping Yingjie said.

Second, more scale, the less water it. \"Originally basin of water can hold 5, now only hold 3 basin of water. The shower water naturally smaller.\" Ping Yingjie said.

Feng Yingjie said that in general the solar water heater with 3 years, you need to clean the scale, and this can also extend the life of water heaters. Cleaning prices, according to the size of the solar water heater is slightly different, for 60 yuan to 90 yuan.

The installation of pipe loop

One drawback is that solar water heater hot water must be imported from outside or inside the top floor, a long waterway, pipeline usually accumulates a greater amount of cold water, the user can not immediately have an open hot water faucet out. To overcome this drawback, the use of pipeline loop is a common approach. Pipeline loop\\ s role is to replace the tank in the cold water pipe, hot water into the pipe, back into the cold water pipe in the solar tank, making in all hot water pipes, so users can get hot in time the. Figure 4-3-8 is the basic loop diagram.

The basic diagram of Figure 4-3-8 cycle

Now due to the development of solar technology, people invented the hot water loop controller, you can easily achieve the purpose of recycling. Recycling programs are generally used in three ways: manually cycle through the program, the timing cycle of timer control program, tap the control of real-time cycle options. As follows:

1, manual cycle program

Circulation pipe installation installed a circulating pump, when the user needs hot water, close the circulating pump switch, water pump will pump into the heat pipe solar water tanks, making the pipeline is full of hot water, so the user an open hot water tap, can quickly get hot water. Shown in Figure 4-3-9.

Figure 4-3-9 manual cycle diagram

2, the program cycle time

Figure 4-3-10 is an effective cycle timer is started by the waterways schematic:

Figure 4-3-10 start the cycle timer schematic

Principle Explanation: The program is controlled by the cycle timer cycle, when the user set the Timer 1 is turned on, open loop control solenoid valve 2, pipes in the water pressure is reduced to 1 kg, and the water signal to the pressure switch 3, the pressure switch because the pressure is less than the starting pressure (usually in the 2 kg) and connected, the pump 4 starts, down to pump water, so the cold water pipe to be squeezed into the solar tank. At this time, cycle time controller based on the user\\ s settings can delay a period of time, so that the pump continues to work to set the time, at which time the user opened the taps soon out of hot water.

Procurement cycle time controller street electrical stores are multi-time controller, a control generally have 10-16 hours, the user can set its own conditions to cycle time, more than 10 segments have sufficient time to set. Controller cycle time set in the cycle time, the average user turn on the tap, and soon you can get hot water.

3, real-time control loop program taps

Figure 4-3-11 is an effective waterway any tap from the start of the loop diagram:

Principles of explanation: When a user opens any water switch 5 (tap), the flow switch 3 opens, and the flow signal to the loop controller 1, 4 open loop controller will pump down the water pump, and solenoid valve open cycle 2, so the cold water pipe to be squeezed into the solar tank. At this time, the user closes the tap, loop controller based on the user\\ s settings can delay 20-160 seconds, set the pump to continue to work until the time, so cold water is pumped into the solar tank, so hang in charge of hot water are hot water, the user opens the tap water out quickly. At this time the hot water pipes will not immediately cools, it should wait until the cold water pipe in the loop again. Given this situation, the controller design cycle time interval of 30 minutes, during which the user turn on the tap, the solenoid valve 2 will not open, recycled water will not flow into the solar tank.

In general, household circumstances, few people with water, the water a long time interval, the time is also more irregular, more appropriate to start using the tap. In the collective environment, the water more time to focus on, such as factories, hotels, etc., were also more water in the water during the water is always water flow, the use of more appropriate time cycle.
