Chinese soldiers loaded: new energy sounded the "assembly"

Central to stimulate the economy ten, which we call "State 10" specifically proposed to strengthen ecological environment construction, support energy conservation projects, strong government support, the environmental protection industry in the coming years with good development prospects, the development of new energy vehicles is "potentially very strong." Science and Technology Minister Wan Gang has also disclosed that the state will implement the promotion and application of energy-saving and new energy automotive engineering and R & D investment in the industrial policy and other aspects of efforts to increase support. To promote energy conservation and the rapid development of new energy vehicles, the ministry will join other ministries in four areas to actively promote the development of new energy vehicles. Including the implementation of national energy-saving and new energy vehicle demonstration projects, large-scale application; public transportation, rental, service, municipal, postal and other public areas of the first to promote more than 30,000 energy-saving and new energy vehicles; learn from international experience, promote the implementation of energy-saving and new energy vehicles to support and incentive policies.

In addition, strong support at the national energy conservation under "renewable energy" Eleventh Five-Year "plan", in 2010 the national renewable energy, hydropower installed capacity of 190 million KW, wind power installed capacity of 10 million KW, solar power inverter capacity of 30 total Wan KW. By 2010, China's renewable energy in energy consumption, the proportion will reach 10%. Therefore, the energy saving policy backdrop, with wind power, hydropower and nuclear-related investments in new energy industry will become big hits. In today's situation, China's military enterprises - China Ordnance Equipment Group courage to build at this point forward, it is in a rare beckons Zhiyong.

Consecutive years awarded as the central enterprise performance appraisal A-level units, among the Chinese enterprises 500 29, 500 manufacturing section 8, won the "Corporate Social Responsibility Award" of soldiers loaded the Group, in 2008, economic and economic scale synchronous growth, industrial structure and the continuous optimization of investment structure, comprehensive strength and social influence growing, the work to a new level.

Just recently its subordinate companies - Baoding Tianwei Group successfully developed and put into operation a set of simultaneous use of solar and wind power 40 kilowatts wind and solar demonstration power plant. Wind resource-rich areas, this design not only provides 24-hour use of wind energy, but also in the day when the solar energy utilization also. More specifically, the panels can be like "sunflower" the same rotation as the sun. With this technology automatically tracks the sun's position, the daily electricity than conventional flat plate solar panels more than 30%, but also makes the technical performance of the plant has reached domestic leading level.

It is understood that Ordnance Equipment Group will continue to invest 30 billion yuan to develop new energy sources, is expected to form in this area in 2015 sales volume of 70 billion yuan. According to the reporter a telephone interview Chinese soldiers loaded the Group a department head Mr. Lei Ming has learned that the 30 billion yuan of investment has dropped early part of the main cast in Baoding Tianwei Group is a new energy and transmission projects.

2008, soldiers loaded Baoding Tianwei Group to focus on "three-step, two main industry, the double support" the development of strategies to effectively deal with the financial crisis, the world economic and financial situation is complicated, unstable and uncertain factors increased significantly the situation , the full completion of various economic indicators throughout the year to achieve the transformer output over 100 million kVA, sales revenue 11.24 billion, profits of 1.22 billion a historic breakthrough, two years ahead to achieve "three-step" second-step strategic goal to become soldiers loaded the Group's new and important industry support and a new level of economic growth, China's power transmission and new energy industry leader.

Cost down pv "parity" online will arrive ahead of time

[wind power price now is 0.6 yuan/KWH to 0.7 yuan/KWH, assuming that the photovoltaic components do lowest price, coupled with the inverter, EVA, power stations with further authors on all other equipment, SUNGOLDPOWER photovoltaic (pv) industry of power generation cost is likely to be below the wind power price] online after 2 ~ 3 years

Photovoltaic BBS on 16th, entrepreneurs say now have photovoltaic (pv) can be realized in 28 countries around the world "parity" online. China photovoltaic "parity" online timetable, also with the photovoltaic modules, silicon and polycrystalline silicon photovoltaic products such as price decline, and the overall system is approaching. Approaches to realize the various companies for affordable access to the Internet, however, there are still different views.

Photovoltaic (pv) parity ahead of schedule or on the Internet

So-called parity, surfing the Internet, namely photovoltaics online prices consistent with traditional sources such as coal-burning power plants generate electricity price forming.

Applied materials companies in the United States is responsible for the solar business a top Dr. Charles Gay, said the company in 2010, the statistical results of more than 100 countries around the world show that there are 18 countries reached parity on the Internet, and in 2012 the number was changed to 28 countries. Which is the main reason of the photovoltaic power generation costs have fallen sharply, at present the cost of each component can be dropped below $1 per watt.

Around China's thermal power feed-in tariff according to different situations and different prices, roughly in 0.4 yuan/KWH, others are higher. In contrast, the domestic photovoltaic still more than double the average feed-in tariff cost.

However, our sun chairman su willy, told CBN (microblogging), due to the Tibet local sunlight conditions good (3000 hours per year), even if the region is 0.4 yuan/KWH of electricity price, also have achieved "parity" online. This let us see the domestic photovoltaic "parity" online some light.

Appear in Tibet, the parity of southern Europe and South America to get to the Internet, in the chairman zhengrong shi, suntech solar power inverter (STP. The NYSE) trina solar (TSL. NYSE), chairman of unstoppable, it seems, is the world's photovoltaic industry brought by the production capacity and product prices fell sharply.

"In 2000, the global photovoltaic (pv) installations of 0.27 gigawatts (GW), is 3.5 GW in 2005, at 27, 2011 G, an estimated 2015 annual growth to 40 ~ 50 G. From 2011 to 2015 is an industry consolidation period, the decline of the cost of, make whole parity online ahead of schedule." Unstoppable said.

Hope the government subsidy and market competition

A number of industries that domestic comprehensive implementation schedule of parity, surfing the Internet, could be in 2020 years ago. And for how to implement the "parity", each company has their own opinions.

Shi is clear, the government's assistance is necessary.

"Both in Germany and other European countries, without the support of the government, photovoltaic industry will not get unprecedented development. Policy is coming, the output of photovoltaic products is big, cost is falling fast." Over the past year, the global photovoltaic installation quantity up to 27000 mw, 17000 mw in 2010, compared to the increased by about 60%.

But he also pointed out that "some company with, the government said they can do the component price is $0.5 per watt, but other companies offer digital government is $0.9 / watt." As a result, the government policy making in the future, is likely to be very careful.

However, Shanghai poly constant solar co., LTD. (hereinafter referred to as "poly constant solar") a top said, fierce price competition can make affordable Internet soon, "only through constant technical innovation, make cost cuts, photovoltaic power generation efficiency in qualitative leap, so that all the authors link to make the whole industry chain, create favorable conditions for parity with access to the Internet." If the government gives high subsidies, many enterprises will only rest, will not exert oneself to do research and development. This is unfavorable for the photovoltaic industry itself.

But our CEO Zhang Yize sunshine that parity Internet need are a few conditions: without subsidies, local market is totally free; Region illumination condition is good, every year more than 1200 hours of light; Land and grid conditions are ripe, can electricity from the grid to achieve full recovery. Suppose one in these three conditions can't meet, so affordable online there are challenges.

Sue willy also stressed that China is one of the biggest challenges is the grid is not open. "If this cannot be resolved, then parity short-term in China is can't see the result on the Internet."

Photovoltaic laid down last year, the feed-in tariff is 1 yuan/KWH, part of the western region makes the construction of the photovoltaic power station, due to the price at least 8% of the rate of return can figure, so in the second half of last year as many firms rush, the bidding is extremely warm.

But LDK (LDK. NYSE, hereinafter referred to as "d") President TongXingXue also said that despite the price down very quickly, but the market is irrational, the manufacturer of pressure is very big still, if cheaper Internet is realized in the component on the basis of the sale, so many companies interested in will be greatly reduced.

"At least from the current situation look, photovoltaic (pv) is likely to be below the first wind power feed-in tariff costs." Get constant solar the top that it is a good idea to wind power price is now 0.6 yuan/KWH to 0.7 yuan/KWH, assuming that the photovoltaic components do lowest price, coupled with the inverter, EVA, authors further on all power stations with other equipment and so on, so photovoltaic industry online power generation cost is likely to be in 2 to 3 years less than wind power price online.

"Therefore, as a manufacturer, we hope in the government access to information, companies are generally profitable, realizes the pv parity, surf the Internet." TongXingXue said.

Defect continuously 300 megawatts of installed capacity in 2009

With the heart of the broad, inclusive sorry you;effect, in fact, even more than at the beginning the boldest expectations, four years, a total of four period of gold sun demonstration project accumulated design capacity nearly 6 gw, only policy in 2009, more than 100 megawatts of gold sun demonstration projects through the construction, the actual approval about

Subsequent years, golden sun capacity rising year by year, installed capacity of 600 mw in 2011, in 2012 the "golden sun" 4544 megawatts of installed gross scale, is the sum of domestic dc to ac inverter installed before, account for half of domestic photovoltaic application market.

Fast horse gold sun engineering became a needle cardiotonic, stimulate the companies continue to enter, only during the first year of policy implementation, the Treasury has provided nearly $5 billion for this allowance.

"Gold sun policies to help our pv companies spent the most bleak moment, cultivate a batch of photovoltaic power station design, planning, operation team, has formed a complete set of domestic photovoltaic power station and operating mode."

A photovoltaic enterprise executives said.

In power plant construction by leaps and bounds at the same time, the defect of hand.

Engineering subcontracting, flagging deal, components, shoddy, heavy construction, light management phenomenon emerged.

In 2010, the ministry of finance announced the cancellation of 39 "not built, shoddy" project, a total of 54 megawatts installed, including the well-known both at home and abroad such as wuxi suntech, RON artest, BP solar power inverter as the owner of the project.

Increased in 2012, the list of shanxi international power photovoltaic power generation, photovoltaic 15 companies such as zte energy, polly.

In fact, after the problems gradually exposed, remedies, soon in component sourcing, will experience the process of dispersing - concentration - and only under the condition of the big problems, small range of mend it is difficult to obtain satisfactory results.

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.

Household solar power inverter can be sold? Also just painted flowers!

As the state grid, which was launched last month on the distributed solar power inverter  service work opinion ", is committed to promoting photovoltaic, wind, natural gas, such as distributed solar power inverter into the national grid, self-sufficient individual solar power inverter, can even hooked up to the money became the hottest topic.

On March 12, in jiangxi province is the first residential users distributed grid-connected photovoltaic projects - LianHuaXian yangs saemaul undong Zhu Jianbing jincheng highway 220 volts in distributed solar power inverter projects by grid tie inverter measurement device installation and interconnection, the hair electricity contract signed acceptance and commissioning, after successfully connected to the grid. 

Yangcheng evening news reporter survey found in guangzhou for several days, however, even if is the most likely implementation of solar power inverter, in a year or two to grid tie inverter to make money is only a "hunger".

Threshold a who has 200 square meters of the roof

"This is a very interesting topic." Guangzhou grid tie inverter bureau co., LTD electric power converter test research institute (hereinafter referred to as "electric power test research institute) director Liu Guojun in yangcheng evening news reporter interview smile said:" as far as we know, university of south China university of technology, the city has solar power inverter, and as a pilot. 

As for domestic small-scale power converter (in addition to the grid tie inverter), almost none."

Why is that? Very simple, the "indifference" of power converter.

 "Our institute made an experimental power converter, is just solar panels area, has been to more than 200 square meters. 

Efforts, achievements of the "first blood" in the transformation of chint solar.

As the largest domestic solar power inverter  construction of private enterprises, chint has built 750 mw solar power inverter and solar power inverter project under construction, which has been connected to the grid in the power station more than half. 

This year the new 300 mw power plant, mostly has also got the project.

Hui revenge show that, due to the European "double reverse" the conclusion is not yet clear, the domestic power converter  supporting policy pending, power converter this year if I can walk out of the "trough" is hard to say. 

But don't panic "bread" has heart, depends on the power converter smoothly, revenge show Hui to fulfill the sales task group issued 5.5 billion yuan this year was "very confident", compared with last year, that number increased by 12.2%.

"In addition to actively participate in the power converter in zhejiang province" five one "comprehensive innovation pilot work, this year we will strengthen and foster, curtain, etc. 

Other advantages in the field of enterprise cooperation in the industrial chain division of labor."

Revenge show Hui said, and "win-win co-operation" of the enterprise, is to chint inverter with charger cost is further reduced.

But problem also subsequently and come.

German photovoltaic inverter with charger is given priority to with access to distribution network, distribution and scale is larger, caused great influence to the safe and stable operation of inverter with charger network, noon peak distribution network congestion phenomenon is very serious, acceptance of distributed inverter with charger capacity is insufficient, the distribution network has become a German photovoltaic industry development the important restriction factor.

 As a result, Germany in 2009 began to cut subsidies for solar power inverter.

Can open the domestic market is the key to save the power inverter

In fact, countries have already realized that could open the domestic market is the key to save the power inverter industry.

After, the western large-scale photovoltaic power inverter, once the darling of many photovoltaic companies.

In July 2011, the national development and reform commission (NDRC) to release the feed-in tariff of photovoltaic power inverter, photovoltaic enterprise attracts a lot of western investment in large-scale photovoltaic power inverter. 

Limited, however, because the west electric power demand, leading to some western photovoltaic power converter is difficult to operate at full capacity.

The analysis thinks, as the world energy consumption big country, China has the world's largest power converter capacity, also has the world's most complete pv industry chain, urban and rural areas in our country has the most populous city in the world the roof of buildings, industrial buildings, civil construction, "open the domestic distributed power converter market, can really save the photovoltaic industry."

"China has 316 million square meters of sunshine good roof conditions of resources, to about 31.6 billion KWH per year, the equivalent of a year on 30 million Chinese residents of electricity every year."

The above analyst data provided by the more exciting.

He also pointed out that the Middle East, for example, the city layout has a lot of solar power inverter roof resources, plus the city paying ability is stronger, better economic basis and has installed the potential scale and potential.

In fact, from last year, national energy administration pushed many times "distributed photovoltaic (pv) solar power inverter", and called for "promoting", for photovoltaic solar power inverter request is "pushing".

And at the end of last year during a state council executive meeting, also put forward "actively explore the domestic photovoltaic application market, and strive to promote the distributed photovoltaic (pv) power generation", "distributed" power level is mentioned for the first time the state council.

Solar power inverter water heater should be more mature to era of hot water to health

Although the solar inverter  has been a household name, but consumer understanding of solar inverter industry, products are not enough mature, this requires our solar inverter enterprises especially the leader on the one hand to do a good job in industry product consumption trend lead to create market; On the other hand is to according to their own products to science and education.

Current solar inverter market maturing, consumers brand consumption and healthy consumption become inevitable.

For consumers, when you buy solar power inverter , decide to buy or not buy, buy which brand, which style to buy depends on the accumulation of brand awareness, product performance and reputation of the brand, and the brand can bring consumer is cheerful personality and self satisfaction.

Such as now with many leading brands industry gradually on the solar power inverter quality health technology breakthrough, which means that the solar power inverter in the hot water bath from pure can be extended to wash the dishes, wash the dishes, cooking, etc.

Every aspect of daily life. Also marked at the same time, China's solar grid tie inverter  production from absorption of heat, heat competition era towards health and hot water.

For solar grid tie inverter products in service marketing, must first fully understand the needs of customers, understand customers' concerns and expectations, can be targeted to take measures to meet the needs of customers.

Investigation in different ways, can use the questionnaire survey, site investigation, telephone pays a return visit, such as door-to-door visits to investigate for a new user.

Currently solar grid tie inverter enterprises can focus on considering the contact authority website consumer network investigation, telephone pays a return visit, the door back three ways.

Second, channels, strengthen the construction of the dealer service network.

Currently most dealers are in sellers and sell the latter plays a dual role, specific to the after-sales service are generally performed by installation personnel.

Caused by the dealer network is not sound after-sales service stand out, not in time to solve this problem, you need to strengthen the construction of dealer service network, the development gap outlet dealer or third party service providers.

In addition, at present the country to advocate energy conservation and emissions reduction, at all levels of government and township government subsidies to promote solar energy water heater popularization and promotion, the installation of the solar water heater has become a highlight in the new rural construction, become the important symbol to improve rural residents living habits.

The starting of the rural market, attract channel integral sinking fast, flat solar water heater industry.

Solar water heater enterprises can change the past from prefecture-level agents to the traditional model of villages and towns retailers, directly in the villages and towns established retailers or stores, make the channel more flat.

Similar applications include high voltage dc output,solar power inverter stationary type dynamic reactive power compensation, etc.

 At this time of the power electronic technology has been able to realize rectifier and inverter with charger , but working frequency is low, limited in the low-frequency range.

1.3 inverter with charger era

Into the eighty s, large scale and very large scale integrated circuit technology rapid development, laid the groundwork for the development of modern power electronic technology.

Will fine processing technology of integrated circuit technology and the high voltage large current technology organic union, appeared a batch of new type of all control power device, the first is the advent of power M0SFET, led to the small and medium-sized power to the development of high frequency power supply, then the insulated gate bipolar transistor (IGBT), and for large and medium-sized development brings opportunities to high frequency power supply.

Thereafter, MOSFET and IGBT of power electronics is the traditional to the modern power inverter transformation.

 According to statistics, by the end of 1995, power M0SFET and GTR in power semiconductor devices on the market has reached the point of vie, and replace GTR with IGBT have been established in the field of power inverter. 

New device not only provides the ac motor frequency control of motor speed the development of high frequency, make the performance more perfect and reliable, and makes the development of modern electronic technology constantly to high frequency change, for efficient energy saving, material saving of electrical equipment to achieve small, lightweight, mechanical and electrical integration and intelligentization provides important technical foundation.

2. The application field of modern solar power inverter

2.1 computer efficient green power supply

Rapid development of computer technology to lead the human into the information society, but also promoted the rapid development of power technology.

In the eighty s, the computer fully used the switching power supply, take the lead in complete computer solar power inverter. 

Then switch power technology successively in the electronic, electrical equipment.
