China's urban area of single-family, villas, industrial buildings and public buildings

Rural bungalows and independent courtyard, unused fields are photovoltaic market.

As long as the policy in place, through a distributed grid tie inverter barriers, domestic excess capacity can be absorbed immediately, the relationship between supply and demand balance.

China has the world's largest photovoltaic battery capacity, the most complete pv industry chain of manufacturing, most of the public, industry and residents by building roof, broad enough sunlight irradiation resources, has the highest energy consumption demand.

Grid as long as let go of hooked up to the gate, industrial salvation, blessed people, countries, what need to see the face of Europe and America.

Texas a&m university will build the world's largest solar energy research center

Texas a&m university (TexasA&MUniversity) is planning to build claims will become the world's biggest solar energy research center.

The new solar energy center to assess renewable energy technologies, development and test, focus on solar technology.

But golden sun project threshold is mw, Several joy several sorrow

Originally the most of Europe and America's most admired is accord with the characteristics of PV inverter application has huge potential of distributed small rooftop market completely excluded from the policy subsidies, that in itself is being questioned.

With the 2013 the ministry of finance is no longer the demonstrative project of new gold sun apply for examination and approval, golden sun project to the final moments of life, now how to complete the project become the urgent matter.

"To see many companies looking for roof, sincerely want to: gold sun stop! In the future all supported by power photovoltaic power station of profitable investment policy, please don't come again."

Liu Jianzhou says plaintively, "gold sun was originally used in photovoltaic demonstration project declaration, is for the sake of the pv-tech application start stage to promote the development of industry, now has become a deformity of the policy, the government is hoping to support enterprise, only to find the component manufacturers were pulled to the deep each other!"

Since golden sun project implementation, in fact, many of the photovoltaic companies involved and as the policy to an abrupt end, to those who once the golden sun as key enterprises of enterprise development, how to recover upfront investment has become the problem had to be taken into account.

"Light" d also didn't do last year project has 55 megawatts, "Yang Yanbo told new financial journalist.

And another is located in hebei grid tie inverter enterprise staff said "for golden sun project, what are we to say" before, the enterprise once get order one golden sun.

Relative to the embarrassment of the manufacturers, enterprises can in golden sun project costs less to sit tight.

Gold sun, on the other hand, since the policy execution, having to face an embarrassing fact that money given to you but didn't see, according to the capacity of relevant data show that since 2009, approval of demonstrative project of golden sun only realized on generating capacity by 40%, and other projects are not completed due to various circumstances combined or extended.

Gold sun policy at the beginning of the release, during the pv component prices are high, photovoltaic (pv) grid by grid, the domestic application of photovoltaic (pv) lack of awareness of the environment, gold really played the domestic photovoltaic solar photovoltaic project application demonstration, explore the role of the market.

Gold sun, supporters say, have a profound impact on the development of photovoltaic industry in China, left a important in the history of China's photovoltaic (pv).

In order to promote industrial innovation, accelerate the matching between the industry and industry, materials and equipment, greatly reduce application products cost and so on has carried on the beneficial exploration, if there is no gold sun, rooftop photovoltaic market in China are likely still a piece of desert.

A photovoltaic enterprise executives did not want to be identified, said gold sun not one size fits all, suggested to golden sun demonstration projects stay for three years lag phase, can be taken during electricity price subsidies and gold sun "double-track system", through the practice to make more accord with the situation of pv subsidy policy, to further need experience.

"The project itself for China's photovoltaic industry is the first shot, the first maneuverable policies, the role of obvious, just now the situation has changed, the policy should also corresponding change," Zhao Yuwen believes that "the most important is implement good feed-in tariff policy, become construction project a get subsidies for calculating power generation quantity of subsidies for a long time, so reducing short-term behavior."

After a step foot into pv industry, Yang Yanbo ever felt it is a lifelong career in the industry, just now, the left is on the schedule.

Gradually away from the photovoltaic industry, of course, there are golden sun project, the once brought glory to industry and controversy, transitional policy of excitement and frustration.

Israel launch new SolarEdge inverter and power optimizer

Leading global end-to-end dc to ac power inverter optimization system and monitoring solutions provider SolarEdgeTechnologies announced for north American market to launch new series inverter and power optimizer.

European Union imposes punitive tariffs on stimulus subsidies policy launch pv concept brewing on the offensive

The commission agreed to domestic wafers, cells, components, a 47% average tariff, the move or make domestic photovoltaic enterprises suffer great losses.

However, there are domestic brokerage, said the move could lead to domestic pv market focus on fostering policy, thus effectively hedge risks in overseas markets.

Domestic photovoltaic industry, improve the investment environment is becoming A big probability events after much photovoltaic of a-share stocks in A downturn, or for the jedi counterattack opportunities.

The European Union will impose punitive tariffs

Recently, the European commission confirmed to impose punitive tariffs on solar panel imports from China.

The European commission, according to the draft copy of the European Union will be in China's biggest solar cell maker, tariffs, the new tariff measures will take effect on June 6.

Suntech, sai d, TRW and ja rate were 48.6%, 55.9%, 51.5% and 48.6% respectively, the industry's most other cooperate Chinese company will pay the tariffs of 47.6% on average, and not with the company will face a tax rate of 67.9%.

Great Wall securities in their research report, according to the European market in 2012 photovoltaic exports accounted for the proportion is about 55%, is expected to drop to around 35% in 2013; Even so, still can make domestic photovoltaic enterprises suffer large losses.

Have a profitable business component suppliers will become the market leader.

In 2015, the solar industry will see strong growth and revenue, it will restore people's confidence in pv manufacturing, and make people further investment in factories and the development of new technology.

30 YLDP series 1000 kw version of power converter in her dragon industrial park North America successfully delivery.

Her dragon has achieved a major breakthrough in the photovoltaic power supply into the U.S. market, and thus began to accelerate into the north American market.

By the United States a EPC companies invest in the construction of photovoltaic power generation project is located in the eastern U.S. state of New Jersey.

Project all adopted her dragon power of 1000 kw photovoltaic inverter north American version.

This product is already a dragon grid tie inverter for the grid access standards of special research and development, now has passed the relevant certification in the United States, conform to the grid access requirements.

Before that, the Canadian market production inverter and is dedicated to provide you with marketing and service of her dragon power Canadian companies have set up last year.

At present, produced by the 1000 kw inverter has local offline success in Canada, and has won the product certification.

Not only cleared the market access barriers in Canada, at the same time, the marketing services network of the north American market is continuing to improve and optimize.

As this batch of order delivery smoothly, her dragon power will further strengthen the marketing and service team construction in North America, to accelerate market development and layout of North America.

The future of the pv inverter within the component

Broker: stimulate domestic subsidies

"Daily economic news" reporter noticed that due to the final decision still remains variables, combined with the domestic related supporting policies may speed up the launch, the power inverter still has the potential to continue to improve the environment.

Sinolink securities (market, funds, stocks, visits), according to a research report pointed out that if the policies are correct, in June began to the high tariffs will be accelerated in the second half of the domestic photovoltaic industry reshuffle and temporary output contraction, but final variables is larger in December.

Because the Chinese government may still through high-level negotiations or countermeasures, such as polycrystalline silicon double inverse) affect the final result of December, at the same time, as a result of tariff falls installations and damaged the local dc ac converter downstream developers may change in the ultimate justice of the eu.

But these will not hinder some high dependence on European market, in the second half of the money situation tense enterprise capacity elimination.

In addition to the final variables remained outside, the event itself may stimulate domestic pv subsidy policies to speed up the launch, it is also one of the potential upside of photovoltaic industry.

"This event is expected to spur domestic grid tie inverter subsidy policies to speed up the launch, the government will also take a series of trade measures." , changjiang securities (money, stocks, interrogation) in his research report said, "we continue to look good in the domestic market launch of photovoltaic application domain investment opportunities."

Great Wall securities research report also showed that the stable growth in the next three years the global pv market, to capacity continues, industry development pattern gradually to the equilibrium of supply and demand; Domestic positive policy will significantly boost market sentiment, raise plate valuation, trend of the market brings the entire plate.

Construction of the distribution position of all grid tie inverter projects, as well as the operating condition of each plant.

Staff member introduction, now the whole control system by monitoring equipment connected to the Internet, convenient timely to understand distribution around the power inverter operation; By recording power information, also can realize various scheduling to balance between the source.

"Improvements a lot now, investment of photovoltaic power station has more people.

But in 2009, photovoltaic power generation cost is high, the supporting policy is not clear, there are few companies willing to participate in the photovoltaic projects."

Hainan day Xu Xiang into electric power co., LTD.

General manager, told reporters that "as the company high-quality goods project demonstration effect amplified, a growing number of pv owners have begun to actively cooperate with us."

According to reporter understanding, at present, in the electric power in haikou, hainan day high, ChengMai, qinlan, TunChang, three sand investment construction, 81 megawatts of inverter charger and scenery complementary demonstration projects.

After put into production, these programs can provide about 110 million KWH for hainan province every year of green electricity, (25 years) during the service life can provide about 2.75 billion KWH in green energy, equivalent to save BiaoMei 931000 tons, 2.222 million tons of carbon dioxide.

Although, the company is in good working order, but Xu Xiang pairs the whole photovoltaic industry considerable concern, "to do or want down-to-earth, pragmatic, state of mind to put away."

Do, in his opinion, new energy sources such as grid tie inverter , although not high and new technology industry, but also a system engineering.

Enterprise should not only understand the operation of the project, but also grasp the national policy; Should not only understand technology, knowledge of technical standard, finally must also have a professional team to complete these.

According to Xu Xiang into developing solar can be used the European model is right, because the European model is came out.

Family plant, in our country not only has a relatively mature grid tie inverter support and real demand

And with the enhancement of social environmental protection consciousness, in the development of our country will have broad space.

Is not unattainable

It is understood that at present Beijing and shandong distributed power inverter project has a total of 2 families grid.

Because of weather and local distributed photovoltaic effect to the annual sunshine hours, distributed in different parts of the photovoltaic power generation efficiency and investment return period is a bigger difference.

Henan kaifeng citizens Yang Xinyu told reporters that his home electricity per month more than 100 degrees, daily electricity consumption of up to five degrees.

He is going to install a set of 2 ~ 3 kw home power plant. Don't know the installation cost and power plant covers an area of and other related details.

With his question, the reporter arrived at henan normal university, on the top floor of the "photovoltaic material key laboratory in henan province", see the built in 2009, 5 kw ac/dc automatic tracking pure sine wave inverter and LiWang ".

The plant is currently the most advanced distributed generation system, unlike journalists ever seen flat layout, four solar panels matrix, like the four giant "stalk" standing on the platform, upturned face, always toward the direction of the sun, and fully absorb the energy from sunlight.

The lab director often high side compare their plant to "sunflower", think this layout can maximize the conversion of solar energy.

Often feel high, residents' family grid tie inverter "best or spontaneous for private use. "Meet the needs of plant for private use, can greatly reduce the upfront investment of equipment."

Type power station, in a nutshell, for private use only need reasonable number of panels and the battery can be fully competent, rather LiWang (more than electricity available) plant essential inverter costs, will account for 50% of the entire input, type than the private cost increased by 30%, and perfection blindly pursuing big don't have to sell electricity.

Dream of science and grid tie inverter revolution in the holy land

On this piece of land full of passion, there is a rising city - jiaxing city science and power inverter .

Was founded in 2003, jiaxing science and technology city, in zhejiang provincial party secretary xi jinping's then, driven by tsinghua university and zhejiang hand, zhejiang qinghua Yangtze river delta research institute was set up and take the lead. Here from the start on a high.

Founded 10 years, the investment of 3.6 billion yuan, jiaxing science city rise of ground.

In the first phase of the core area of 3.65 square kilometers of land, created??? More than $5.6 billion in revenue in 2012, average annual growth of 250%.

Drive in the fixed assets in 30 billion yuan of above, increase the grid tie inverter of 46 billion yuan.

Here has become the zhejiang introduction of famous universities in the yard of a flag; Here to become a major platform for zhejiang innovation-driven development, bearing the lead and the "south lake dream" to promote the development of science.

Jiaxing nanhu district party committee secretary Sun Jianhua want to get more, is how to make the south lake area development go in complete province front row.

Recently in an interview, he told the science and technology journal reporter said that the original development model has not adapted to the south lake area innovation driven development; To speed up the city of science and technology leading role play, accelerate the economic transformation and upgrading, the key lies in the organic combination of the development of science and sine wave inverter city and regional economic development.

Horns trend appeared "dual-core effect"

"To serve local transformation and upgrading, science and technology city bigger and stronger in the first place."

Jiaxing science and technology city management committee director, the deputy district ChangSunXuYang witnessed the development of science and technology city history, he said, "science and technology city is small, but there are characteristic.

IGBT manufacturers to develop grid tie inverter markets, targeted low voltage applications

IGBT operators are actively take into below 600 v low voltage applications.

Global economic power inverter, coupled with the main application market increasingly competitive, makes the IGBT industry growth slow lately.

To create a new growth opportunity, IGBT industry hence is committed to research and development new technology for low voltage applications and product solutions, even toward 12-inch wafer manufacturing development.

Yole Developpement solar inverters sector analyst Alexandre Avron

By the effects of global government reduce the renewable sources of energy and transport, insulated gate bipolar transistor (IGBT) components and module manufacturers are in a difficult situation.

According to Yole Developpement statistics, most manufacturers of IGBT, packaging company and related passive components manufacturer in the 2012 recession (figure 1), thereby encouraging relevant manufacturers change the policy of IGBT wafer and packaging production, issue the industry back to previous rapid growth trajectory.

Expand market for low voltage grid tie inverter factory production strategy shift

At present, almost all manufacturers of IGBT in 600 V (V) related power electronics application market competition, ranging from solar Inverter to motor drive (makes).

Existing main providers such as in Germany's Infineon (Infineon), Tokyo, Japan's Mitsubishi motor (Mitsubishi Electric), and have available block up to 3300 v voltage element advantage Fuji Electric, Fuji Electric).

The industry also extends under 1700 kv voltage applications; This market, is the industry's most competitive applications, because almost all of the power electronic components manufacturers, can provide application below 1700 v IGBT component.

If in revenue terms, however, is the market value of 600 ~ 900 v products the largest source of contribution.

Trust in SMA group support, megavolt grid tie inverter will further strengthen its product design, quality control and after-sales service

At this point, layout of domestic inverter market since 2012, huizhou day finished pv inverter energy development at the domestic level, investment, construction, project management, grid tie inverter , financial disposal, holding operations all closed-loop chain, successfully formed the development of new energy power project complete, closed type and operating system, and starting from the energy storage and power system operation mode.

SKY's business throughout Europe, Asia and America, is a professional in terms of system development and integration of IPP.

Great 'lakes Energy company (GLE) in 2008, is set up in response to the Ontario's green Energy solutions. Since its establishment, the company in Ontario, has been successfully installed more than 150 pv projects. GLE specializes in commercial and residential rooftop pv project solution, and meet the Ontario power authority feed-in tariff program standards. GLE, Ontario, has been the photovoltaic industry leading enterprises, is also the most photovoltaic industry contractors by the users trust.

Why do you say about this grid tie inverter in the short term pessimism

And is bullish on the future long-term investment opportunities? Because in the short term, both in terms of the is given priority to with chemical method of polysilicon production, raw material or the component production scale effect, all could not see the product cost the possibility of a sharp decline, coupled with serious supply exceeds demand and capacity in Europe and the "grid tie inverter" factors, in the short term investment opportunities opportunities were limited.

The future for a period of time, components of the highest conversion rate has been tending to actual implementation possible, integration of industry scale effect is also limited to lower cost.

Investment in the photovoltaic industry, as a decline in the cost of we most care about problems, though, don't think that Moore's law applicable light volt grid tie inverter but believed that the greatest opportunities of cost reduction in polysilicon feedstock, due to technological advances, reduce the cost of polysilicon production is remarkable.

Learn material, I believe as long as the storage of the raw material is enough big, with the improvement of grid tie inverter, production cost reduction is only a matter of time.

The wind grid tie inverter progress is likely to appear in the United States, we have received a lot because of advanced foreign wind grid tie inverter to investment request.

If polysilicon production cost can be decreased from $20 a kilo to a $10 or less, what will bring in the wind grid tie inverter competitiveness, it will be a "money" the arrival of the era.

When everybody don't look good on the market, is perhaps the most worthy of investment.

Red Hui: agree with you on the silicon raw material to produce the competitiveness of the future due to technical progress to bring costs down judgement and confidence, believe that human the infiniteness of the cognition of natural and wind grid tie inverter progress of great ability.

Is different from you on power inverter in the short term, the four or five years is worth watching this analysis, I think the investment in the power inverter, the secondary market can not to focus on one or two years, because it is in phase to inventory the cruelty of integration.

In the primary market, however, from now on, industry capital should stay focused on market opportunities.

I time analysis of the current pv market is: starting from the middle of industry consolidation takes four to five years, during which is divided into two stages, and the price of the first stage is irrational stage, because of the local governments and financial institutions with competitive enterprise bankruptcy damage not don't want to see, it is only through brutal price strangulation of crowding out, so as to realize the relatively reasonable supply and demand, this stage need 2 years time.

The second stage is rely on technological progress to bring cost down the price of rational stage, from quantity to quality differences between different enterprises will take place during this period, this time by any one, secondary market is worth strategic investors pay special attention to.

Agree with you about power inverter relies on scale effect makes little sense to slash costs, but the difference is I the comparative cost of more emphasis on the energy industry.

Distributed grid tie inverter: opportunity or show?

Analysts think China now the development of distributed grid tie inverter  has catch little amplification phenomenon, emphasis should be placed on the industrial and commercial enterprises rooftop grid tie inverter, and household grid tie inverter plant at present is not suitable for large-scale promotion, market-oriented operation needs to be time. 

Chinese renewable energy industries association, zhang ping when accepting a reporter to interview, points out that the distributed grid tie inverter is indeed good news for industry, but if the policies encourage en-masse horse, put on a new round of "their" new energy fields, grid tie inverter, not only can't help it may worsen the plight of the industry. 

"Catch small amplification"

Should "leading role" in a distributed power converter  market business rooftop power plant over the past few months, progress has been slow, China economic times reporter in an interview last week, found that the popularity of industry and commerce of distributed power converter far less household power converter. 

Photovoltaic roof based on the experience of developed countries abroad, distributed power converter, for industrial buildings, commercial facilities, and large public buildings more attractive. 

Beijing's first family of power converter director kay said, "the factory has a very large area roof, electricity will also be larger; on the other hand, commercial and power converter prices for two to three times higher than residential electricity, if countries can have subsidies, investment return period may be shortened to four or five years." 

And solar power inverter  in the family field, although has successful owners emphasize family solar power inverter is not difficult to build, as long as the choice of formal manufacturers and installation personnel can understand the technology, but that doesn't seem to be the case. 

Ren Kai when the initial plan for professional solar power inverter plant construction companies, but several large companies have said 3 kw of the project is too small, profit limited "disdain". 

His Ren Kai embarking on the design of distributed grid tie inverter, assembly, maintenance and after-sales and a series of work. 

"Many owners are now in taobao buy component."

After build their own model project, Ren Kai seize the business opportunities and manufacturers established strategic cooperative relations, set up company to provide clients with "one-stop" commercial service of distributed solar power inverter system integration, to survive in the cracks. 

Liar clamor didn't lie to the grid tie inverter court

"The liar is so rampant, incredibly dare to make a phone call to ask if there is any help he paid payment for goods." 11, Mr. Zhang call our hotline 96369 news said, grid tie inverter there are three days after an attempt to scam money liar and give him a call.

Mr. Zhang in the provincial capital runs a stainless steel window business. On April 8, he received a phone call, the other claim to be chase qiao tou hui minority autonomous county liberation of north road army logistics department minister.

Mr. Zhang said, the grid tie inverter other party said to him to make "force" a dozen meters window. Mr Zhang have one bite agreed. 

But then, the minister of "logistics" and let Mr. Zhang help camouflage tent to order. Mr Zhang said he was just wondering, next to his store has several tent business, "grid tie inverter" not to look for them, how to find him? 

But Mr. Zhang in order to preserve this 10 meters of window business, solar inverter  there will be no more ask. So, Mr. Zhang let son online search manufacturer of military tents. Mr Zhang said he had been completely random looking for a manufacturer,solar inverter not "logistics minister" assigned to him. 

After the search to the results, suggest we born to search to the Beijing tongda solar tent technology co., LTD. Contact way told the secretary of "logistics". Before this, Mr Zhang's son back to the factory,solar inverter but factory provide the machine always couldn't get through, only one mobile number. 

Mr Zhang says, before long, the secretary of "solar inverter" is to call him, say has collected 5000 yuan in payment for goods to the other side, let him help to paid the rest payment of 15000 yuan, in the afternoon to go to "force" measurement, we will put the money paid to him. 

Mr. Zhang, a listen to want paid payment for goods, we immediately rejected. "Logistics minister" also politely persuade at first, sine wave inverter  but have been rejected, Mr Zhang minister of "logistics" has become angry from embarrassment,sine wave inverter and claims that don't help in a military court. 

Sum up Mr Zhang says this words obtained. Mr Zhang said, I am also your kindness to help him find manufacturers, how to but want to go to the court.

That afternoon, Mr Zhang went to the window size,sine wave inverter large flux'd like to see the minister of "logistics", by the way. But who know that Mr. Zhang once again to call "logistics minister", said he had to chase after the minister of "logistics" phone is shut down. 

Mr Zhang said, shortly after minister of "logistics" to turn it off, Beijing tongda factory had give him a call in traversing payment for goods. Then he the manufacturer calls for many times, but all the telephone has been couldn't get through. Secretary of "logistics" also disappear. 

But to suggest business outside, "logistics minister" suddenly appeared, again ask tents. Mr Zhang immediately that the tents had to, would like to see "logistics minister".

Although "logistics minister" a promise, when Mr. Zhang told to go to bank again to find him, "minister of logistics" is evading on various grounds, refused to meet with Mr Zhang. 

Grid tie inverter supplier will face severe challenges

According to market Research firm IMS Research, the latest quarterly report, for her dragon power inverter , 2013 will be another challenging year, global revenue growth did not change, and shifting from the traditional market of major changes will occur.

Due to the power inverter price falling and new markets such as Japan, China, India and the United States is difficult to penetrate or lead to its core cannot make up for the decline in the market, the global top ten manufacturers of inverters are very likely to suffer.

Recently, leading power inverter supplier SMA and Satcon distribution earnings warning and filed for bankruptcy indicated that at present all the power inverter supplier suffered serious challenge, in 2014, before may not improve. 

Recently, IMS Research released "global PV inverter  market" quarterly report predicts global PV inverter capacity in 2013 will achieve double-digit growth, reach 35 gigawatts (gw).

Inverter, however, revenue will not increase, because manufacturers try to penetrate emerging markets for market share, in a highly competitive market environment, the price of grid tie inverter is expected to decline. 

2013, inverter geographical changes in market demand and continuous strong price competition will pose serious challenges to the leading PV inverter supplier.

Although the United States and some of the major Asian countries will be how many make up with the demand of the market in Italy and Germany,grid tie inverter but for many leading inverter supplier, is not easy to enter the market. 

In 2013, inverter manufacturers will continue to face challenges including certification standards and low cost base and local manufacturing requirement and the fierce competition from local suppliers.

All of these resources to help him save a lot of things,grid tie inverter also saved a lot of money

But even so, calculate down, also spent 20000 multivariate.

Buy inverter, grid tie inverter, making concrete pier, tripod, etc, he only took less than two days.

Beijing shunyi household grid tie inverter, such as the sea is simply working for a foreign grid tie inverter enterprise's logistics department, which for him to buy grid tie inverter equipment provides a great convenience, but he said "walk a little detour" when assembly, so that all grid tie inverter equipment investment 42000 yuan.

He thinks the actual investment 30000 yuan.

If you're not in the industry, that can only be self-taught solar grid tie inverter enthusiasts.

Anhui first solar grid tie inverter users Kong Qingbin tells a reporter, he works in insurance company, to learn is computer application.

Professional and job won't seem anything to do with the "electric", he is a complete solar grid tie inverter enthusiasts.

He have long been interested in solar grid tie inverter.

His house balcony,solar inverters are fitted in the car, even the daughter room bedside lamp is using solar inverters to power supply.

In 2012, he bought 2 pieces of solar inverters from the Internet, the total capacity of 500 megawatts, installed on the roof, for part of the electrical power in the home.

In march, he will upgrade to 1500 kw solar inverters equipment, or from the online purchase of equipment.

Henan first wang yong is a household solar inverters users photovoltaic enthusiasts.

He was kaifeng jin chemical industry group, a mechanical maintenance man, but his mother was an electrician.

Small, under the influence of the mother, he would like to just dig in the circuit, especially interested in solar power.

In order to buy equipment, he joined a QQ group, group brings together photovoltaic lovers all over the country.

By within the group communication, he bought a 10000 yuan online solar inverters module and storage battery, start to design form a photovoltaic device.

Why grid tie inverter is that investment threshold?

First is investment threshold. To seek to maximize the grid tie inverter conversion efficiency, plate is laid at the king's south, is 25 to 40 degree Angle with the ground slopes.

In this ideal condition, the common three if you want to achieve self-sufficiency, electricity, about 3000 megawatts of grid tie inverter equipment need to install. 

Based on current market conditions, the total cost of the system of about 40000 yuan, the average life of 25 years, recover the investment shall be 10 years, covers an area of 30 square meters - regardless of the economic cost or the cover, is a "threshold" for individual users.

Followed by the power inverter of the threshold.

Individual users apply for distributed power inverter projects, to provide the residential area industry authority and the adjacent "agree to install" certificate issued by the owner. 

Electric power inverter company said a staff member, many applicants "fail" on the license, "rooftop solar water heaters, some village to build a power inverter project need to move the water heater, water heater of the master didn't want to."

Moreover, distributed power inverter projects will cause certain reflection, and power inverter devices on the market almost no retail channels... 

Given the reality of Shanghai shortage of land, high-rise buildings, dense, Yang Xing said, want to large-scale promotion of distributed photovoltaic projects in the city is very difficult, " sine wave inverter  system is suitable for independent or semi-independent villa, with DaWuDing units and some universities enterprise demonstration garden area, subject to the limit of the factors such as land, large-scale promotion has the certain difficulty, in the city center to the filed of individual users are mostly in the sine wave inverter practitioners."

"Roll out", a single project quality difficult to guarantee

The overall quality of the pv project involving equipment quality, installation technology, from several aspects, such as building structure detection is very difficult to cover all of the sine wave inverter, particularly in terms of building structure, the user should ask professional third party verification agency, for example, a building roof bearing, such as wind, lightning protection effect.

Include, for example, sine wave inverter, steel, cement tank, 1000 megawatts of photovoltaic equipment need to be set up on the roof of a part of the total weight about 300 kg or more, "for example, some because of the city's appearance environment needs reformation" ping changed slope roof, not bearing, mainly ACTS as landscaping."

"Currently 6 individual users, because is the personage inside course of study, familiar with related technology, after testing, they install equipment quality is very good also.

If later spread to do, is relatively difficult to assure the quality of the individual projects." Yang Xing said.

According to data shows, electronic materials used in the power inverter capacitor foil is mainly divided into power inverter foil (also called light foil), corrosion foil, foil, mainly process on different depth, power inverter foil after corrosion become corrosive foil, and then processing for the foil, to foil can also be referred to as the electrode foil.

Electrode foil is the key basic material, power inverter capacitor production 30% to 70% of the cost of power inverter capacitor production, about 80% more than the demand of electrode foil are from aluminum electrolytic capacitors, electrode foil so highly dependent on the development of power inverter capacitor industry.

From grid tie inverter capacitor industry development prospects, in spite of ceramic capacitors, film capacitors, tantalum capacitor application of aluminum electrolytic capacitor caused a certain impact, low end of the grid tie inverter capacitor was gradually replaced, but in the field of high voltage, large capacity, grid tie inverter capacitors because of its superior technical characteristics, the future will have a significant market position.

Future with frequency conversion technology, energy saving lamps and lanterns, grid tie inverter, wind inverter, smart grid tie inverter represented by the rapid development in the field of green energy saving, and represented by 3 g communications equipment updating and represented by high-speed rail, electric cars transportation development, have produced a huge demand for high voltage capacitor.

But at the same time, we should also note that the wind inverter capacitor industry, there is a strong cyclical fluctuations to upstream of the electrode foil industry also brings no small impact.

From the past, electrode foil industry showed strong periodicity, falling demand will have excess capacity, and demand booming again when will appear in short supply.

In 2012, for example, aluminum electrolytic capacitor with wind inverter material falling demand, prices, product sales fell, the insufficient capacity play, capacity utilization is only 50% or so, unit costs rise, operating income is affected.

How to promote grid tie inverter and building integrated development

With the improvement of economic construction and people's living standard, people on environmental and solar inverter problem is becoming more and more attention, environmental protection and energy saving has been the focus of the topic to society.

Architecture is a clever music, architecture is the art of stand...

Once had numerous compliments describe building, because different buildings or novel, or beautiful,solar inverter or grand by numerous factors, such as attention, "he said. 

In this paper, the applications of solar energy in residential buildings and the problems existing in the research, and puts forward personal opinion, for reference only. 

Key words: solar inverter; Integration development; Building solar power inverter efficiency

1 introduction 

At present, in the eleventh five-year plan "energy conservation and emission reduction" goal system, how building for energy saving to the government institutions,solar power inverter experts and scholars and enterprise common concern. 

There are statistically, total building solar power inverter consumption in China accounted for 27.45% of total energy consumption, building solar power inverter conservation is imminent. 

In 2006, the state ministry of construction officials said that during the period of "11th five-year plan" the overall goal of building energy efficiency work is: a total of 101 million tons of standard coal, accumulative total construction energy conservation construction area of 2.146 billion square meters, in which new buildings 1.592 billion square meters, grid tie inverter the existing building area of 554 million square meters. 

At present, the roof we can see all kinds of grid tie inverter, it is like color TV, refrigerator has gradually become the basic elements of people's life. 

But these spontaneous purchase and install grid tie inverter is only residents, not as a specialization of systems engineering to consider. 

Thus it exposed some problems, different levels of restricting the application of solar energy in residential buildings.

And even in some cities, the government has issued a ban on installing solar water heater, make the development of solar energy water heater encountered great difficulties. 
