New energy grid tie inverter what the root cause of the problem?

Although our country new energy grid tie inverter performance, but also appeared some problems, this is the objective facts.

According to the national energy administration data, the 2012 national abandoned about 20 billion KWH grid tie inverter,grid tie inverter hours average utilization ratio declined in 2011, individual provinces (area) grid tie inverter utilization hours down to about 1400 hours.

Why is this?
Chinese electric power inverter an article analysis thinks, "this can't be a link or a department, unit, and can only be systematic and global problems."

The national energy bureau about be power inverter in 2013 and given the related work of circular points out, "a large number of abandoned power inverter brownouts exposed the problems of our country's energy management."

But there are individual media will play to the power inverter enterprise board, don't think wind turbine inverter enterprises purchase of new energy and new energy investment access project.

To this, a clear picture of Inner Mongolia energy bureau chief Wang Bingjun. , he thought, "renewable energy law" in the word "full of indemnificatory acquisition" the feeling is very fuzzy.

In such a premise, even did many efforts to given wind turbine inverter company, still face accusations.

As suckers, don't have any legal or policy basis to defend.

If you will be clear, "full of indemnificatory acquisition" implementation of wind turbine inverter quota system online, so, the grid company in accordance with the provisions of the completed tasks, you don't need to bear the blame from the outside.

Now, it is the parties feel very grievance.

Grid tie inverter given, therefore, the problem is not with power grid companies, nor wind turbine inverter enterprise's problem, but a question of policy level.

Based on this, we should give up groundless accusations, return to rational reality.

Reporter survey found that now has three significant problems in the new energy grid needs to solve.

This power converter ratio is only in the United States more than 3%.


According to the national energy administration released in July 2012, " power inverter " twelfth five-year "development plan", in 2015 and 2020 and put into operation in our country's power inverter capacity will reach 100 million and 200 million - kw, will power inverter accounts for the total generating capacity of 3% and 5%.

Denmark, on the other hand, less than 5 square kilometers land area, not comparable with vast China.

Facing the complex national conditions, with 5 years in our country through the United States and Europe 15 years of power converter development, implements the catch up.

According to data by the end of 2012, the state power converter company within the scope of scheduling power converter capacity of 56.76 million kilowatts, is 58.5 times in 2005, an average annual growth rate reached 78.8%. 

Grid-connected power converter capacity of 3.33 million kilowatts, "twelfth five-year" since the average annual growth rate reached 372%. 

From 2006 to 2012, the state wind grid tie inverter  corporation areas are wind grid tie inverter utilization hours respectively 1917, 2015, 2004, 2015, 2095, 1928, 2095 hours, with the European and American countries.

Grid is the platform of all kinds of energy conversion and utilization and efficient allocation.

On the given wind grid tie inverter, interregional given showed strong vitality. 

On April 26, 2012 stake grid, wind grid tie inverter, electricity accounted for 28%, including a third wind power by north China power inverter. 

On May 14, 2012, MengDong grid, wind grid tie inverter, electricity accounted for 72%, among them half wind power by the three provinces in northeast power grid.

In recent years, the national power grid companies are actively promote the development of distributed power supply.

On October 26, 2012, the company to the community "about distributed grid-connected photovoltaic (pv) service work opinion"; On February 27, 2013, the company and to the community on the distributed power grid service work opinion ".

From research, standards, and then to specific service measures implemented, in recent years the company has carried out a lot of work, and openly accept social supervision.

Huang Jili think academician of cae, review over the past few years through the course, to say, countries quickly the hard-won achievements in wind power, national grid company has played a leading and supporting role in it.

New energy and renewable energy's national energy administration, deputy director of the department of Liang Zhipeng once said in a meeting, state grid corporation is the strong driving force of the new energy development.

On the one hand, the early grid tie inverter, policy, funding

Interconnection, private capital in the grid tie inverter construction are few merits, but for nearly a year, more and more private companies to politicians of Japan,grid tie inverter to develop the downstream grid tie inverter plant business.

On grid tie inverter, on the other hand, the big push into after, the diversification and monopoly profits, and other factors, driven by signs of state-owned capital upstream development becomes increasingly obvious.

Which predict that Japan's influence on the industry upstream and downstream and the control will be grows,power inverter its potential industrial landscape of the future have a profound impact.

Artest positive chief executive officer of believe in the future,power inverter but also expect government bail-out process can be more clear positioning function,power inverter, guide and standardize the market, "the government should save industry,power inverter rather than blindly save enterprise".

"It's like has had a very heavy disease, solar grid tie inverter but as long as the bailout is proper, the patients themselves can also grind it, perhaps is thoroughly remould oneself."

Meng Xiangan I hope everyone a little more patience, "German in the eight years to a hot industry area, and eventually become the world's largest solar grid tie inverter, in the Chinese market development also needs time to accumulate, you can't rush".

Industry spring or not
At suntech declared bankruptcy reorganization, in domestic solar grid tie inverter were good.

On March 20, the news that the related ministries and commissions will continue to support the development of power inverter policies, including a significant rise in export tax rebate rate,solar grid tie inverter and other more than 10 supporting policies.

On the same day, tianwei change, sunflower, etc more than individual stocks gained momentum.

Suntech bankruptcy and policy advantage good rumors, whether in release solar grid tie inverter bottomed rebound signals?

In fact, since the second half of last year,solar grid tie inverter began to harvest from a series of positive policy and industry level.

At the end of 2012, state council executive meeting issued a series of supporting policies, including encourage households to install, according to the resource conditions for solar grid tie inverter area Internet benchmarking electricity, and implements according to the electricity subsidies for distributed power inverter, etc.

Treasury website also said yesterday, to promote healthy development of the power inverter, the central government will allocate 7 billion yuan funding to start a power inverter to demonstrate the application of 3157 mw.

Jiaxing by letter committee Yang He think result in information grid tie inverter

Our pv industry as a whole recession last year, there are a lot of business failures, at the same time, we use many wafers are still dependent on imports, the core technology is in someone else's hands, "so we are now to focus on the development of silicon from the past, components, batteries, and other areas of the front end, gradually to the equipment manufacturing grid tie inverter , such as distributed generation and grid tie inverter plant integration direction. 

Now the country's good news a lot, I believe that the domestic grid tie inverter spring will come."

According to data provided by China grid tie inverter alliance, so far, more than 90% of the polysilicon companies have stopped production, still in the production of enterprises only five, but chances are falling. 

And according to the research of GTMResearch, power inverter  according to a report in the next three years will have 180 power inverter enterprises on the path of failure or being acquired.

Vice director of China's renewable energy Meng Xiangan believes that "power inverter is the key to the future, is to abandon the number and scale of growth, to the technology and quality growth."

In addition to the two giants, yingli, RON artest, power inverter, renesola inverter with charger , gcl-poly, jinko business while also losing money, but the past relatively good corporate governance, the accumulation of research and development, relatively rational strategic layout, intentionally or unintentionally stepped variation of an industry nodes, etc., various factors of overlay, reserved for its sideways move STH to relatively larger space.

Some no technology and brand competitiveness of enterprises,inverter with charger will face collapse or merged, "competition will be very cruel,inverter with charger can't hold it don't support", director of the center for energy economics research at xiamen university China '.

Depth in industry consolidation on the eve of different mixed capital strength change is remarkable.

Mainly aimed at the power inverter and rural areas of pool

Wang Guangjun to power inverter layer in this paper, the exchange of aerator said the origin of the promotion of demonstration in the southern states, power inverter exchange aerator is mainly aimed at the yuexi, east guangdong mountain ponds and the regional development of the rural power inverter, using power inverter to increase oxygen, the high costs of erection of cable can be avoided.

Wang Guangjun says, guangdong is the largest aquaculture, but the level of aquaculture and extreme imbalance, the pearl river delta region for the high investment and high yield cultivation type,power inverter while in west, east guangdong capacity is relatively low.

15, HangJu tea: hangzhou Bai Ju 30 grams, white sugar right amount, power inverter with charger adding suitable amount of drinking water to immerse, power inverter with charger of tea.ture development.

Learned, maoming a large operating reservoir tilapia aquaculture Chen boss in early to set up power inverter with charger equipment cost nearly 100000 yuan.

Wang Guangjun estimates, "the mountain pool if equipped with aerator, currently 500 jin per mu can at least double production pond",power inverter with charger can also drive the part due to electricity can not farming, aquaculture development in the region.

In terms of geography, guangdong solar power inverter is enough, most of the area in the subtropical monsoon climate zone, a few in the tropics, sunny, RiZhaoLv is high also, in the summer sunshine time was 11-12 hours,solar power inverter and aquaculture ponds are generally in wide area with no shading, good lighting conditions, the use of solar power inverter into electrical energy utilization rate is high.

Because the solar power inverter water exchange mainly in west guangdong, guangdong and other breeding and popularization of the aerator solar power inverter inconvenient area, the pearl river delta region of the farming are mainly high investment and high yield, the pursuit of rapid efficiency,solar power inverter exchange aerator for many people is still maintain a wait-and-see attitude, think solar power inverter exchange aerator can't meet the requirements in terms of stability and power inverter with charger .

"Solar water exchange aerator is a new technology, we also dare not rashly use trade, you first look at the trial how can choose whether to use."

The pearl river delta region of the prawn farmers Chen Sheng told me.

So pearl river fisheries research institute in the near future to the first part of the mountain of popularizing power inverter with charger exchange aerator of farmers, to see the actual use effect and the market situation and make specific development plans.

About the prospect of power inverter with charger exchange aerator Wang Guangjun said that the invention of the solar water exchange aerator is also provides a new direction to the development of aerator, with the development of science and technology, may have a smaller power inverter with charger will be able to meet the needs of farming production.

Install on the battery 2-3 days can run in the rainy day power inverter

Wang Guangjun told this introduction, a power inverter exchange of aerator costs about 5000 yuan, including the price of power inverter accounted for about 3000 yuan, the use of solar water exchange aerator just need to pay a one-time purchase cost.

Power inverter can be used for aquaculture industry also because domestic power inverter now export is blocked due to the United States and the eu's anti-dumping policy, the power inverter price is relatively cheap.

And service life of the grid tie inverter exchange aerator mainly depends on the quality of the grid tie inverter, according to the present the grid tie inverter water exchange aerator is expected to be up to 5-10 years of life.

Since grid tie inverter exchange aerator running test of the year, the grid tie inverter exchange aerator are failure.

Wang Guangjun joked, "we would hope that it will appear some problems, so that we can timely maintenance improvement."

Solar water exchange aerator does not need to run wires, can realize mobile operation, compared to traditional aerobic pond water mixed convection can be more fully, evenly add oxygen, water quality control effect is good.

But mobile operation there is a defect, aerator to edge of the pond.

Currently USES the solution is to use iron wire relatively limited power converter  exchange aerator range.

But with the development of intelligent power converter, the future is expected to achieve full automation, for example, in accordance with the specific situation of the pond to power converter exchange aerator preset program direction and distance.

The current power converter exchange aerator has yet to install the battery.

Wang Guangjun said that in the next improvement will be installed in a removable battery, farmers can according to own need to decide whether to install the battery.

Wang Guangjun estimated according to the current 200 w power converter and battery, aerator can be 2-3 days the rainy day is running, and the solar energy water exchange of aerator disassembly convenient assembly, farmers can also according to their own breeding needs to increase the quantity of solar panels and batteries.

Guangdong area big rainy day is not much, the current solar water exchange increases oxygen aerator can meet basic breeding needs, this can only be qualitative research, breeding density, aquaculture area, solar water exchange aerator power specific quantitative relationship is still in test.
