Distributed power converter projects itself does not attract capital? Germany's case, at least, is worth us pondering and learning.

In 2000, Germany launched the first edition of a feed-in tariff act, which is the industry relishes the EEG act, has made clear subsidising the feed-in tariff model, bill market in more than 40% compound growth after its release.

In January 2004, modified and Germany has issued a new "renewable energy law, which regulates the" priority interconnection, full acceptance of "new wind turbine inverter policy, and subdivide the various types of power feed-in tariff.

In June 2008, Germany introduced the third version of the bill of EEG.

Every policy adjustment, bring the installed fast.

If a feed-in tariff bill is the source of German grid tie inverter rapid development, the financial innovation is the catalyst.

Through a feed-in tariff bill mechanism is arranged, in Germany, as a representative of national power grid enterprises, and intermediaries, to the user distribution electricity price subsidies, and the corresponding management and measurement.

Doing so is that the main benefit of power grid enterprises represents a national level of credit, distributed photovoltaic (pv) power generation project is equivalent to a debt, because reliable income return, for a while, the financial investment institutions funds into in great quantities, Germany distributed photovoltaic projects become a seller's market, buyers take money waiting for the project.

Under the catalysis of financial capital, the whole pv market is a feed-in tariff in Germany law rapidly on the basis of the blowout.

Why overseas photovoltaic power converter has a huge market demand, and a large number of unsold, overseas power plant investment exactly what are the potential risk?

Super day the sun (002506, shares) to chairman "ni lu suspected to run road" of continuous fermentation, caused great shock in the photovoltaic industry.

Downstream of building, the slightly strange industry-specific vocabulary, with the drive of subsidy electricity price become hot, has been more and more components dealer as a digestive surplus capacity, optimize the preferred way of configuration and asset allocation.

Although the company many times to clarify, but overseas arising from the sine wave inverter building and selling risk is more and more attention.

There is no denying the fact that in the current global new energy development background and industry environment pressure, pv power station is not only the current global yields the most stable and considerable investment in fixed assets, and as the core part of tandem upstream production and terminal application, to promote the new energy industry upgrade and application popularization bear the key hub role irreplaceable.

From the perspective of the specialty of building business grid photovoltaic power station and the normal power generation, which means that the value of the asset and returns on IRR model the basic form.

But from the point of the grid tie inverter business, the investment risk to the backend more loans must be quit or sold as a whole.

Plant assets transaction for component business cash flow is the key to the success or failure of building.

On downstream of photovoltaic power station building, although there is no lack of in the photovoltaic industry pioneer and advocate, but in the huge benefits to be expected and unexpected risks in front, the industry is always filled with a kind of delicate.

So, after the completion of photovoltaic power station, really can sell smoothly? Exactly what kind of power station can be represented by European Banks and new energy fund approved the terminal holder? Those who can't sell smoothly plant and there is the hidden trouble which technology?

In 2011, using crystalline silicon components demonstration project allowances for 9 yuan/tile, adopting amorphous silicon thin film components of 8 yuan/watt.

Falling behind, along with the grid tie inverter cost, allowances as 7 yuan / 2012 w, then fell to 5.5 yuan/watt.

Actually execute in the process of changing subsidies standards, extremely complex, in Meng Xiangan point of view, this reflects the government's grasp of the market "is not allowed.

Subsidy policy change seriously lagging behind the market, leading to subsidies and sometimes almost "package for investment", the resulting problem is "expenses", or "shoddy", regardless of long running benefit anyway, "fill" investment cost almost all back, back to multiple one year earn money in one year, this solid sincerely for those who want to do distributed dc to ac inverter, is undoubtedly a blow.

More generally, many enterprises, intentionally or not, to delay the construction of the project cycle.

Yang Guoping Long Chi curtain wall engineering co., LTD power converter department manager said, "this is not speculation, is also a kind of trend.

Profit is the nature of enterprise, is the enterprise survival wisdom reasonable use rules.

Enterprises need capital turnover, at the end of the day is saved for my own savings, according to the price, for the country may affect smaller, more influence for enterprise".

May be gradually realized the subsidy policy, the central government began to "fundamental", one-time to devolve subsidies smaller and smaller.

Li Chongwei cites the example of zhejiang province, was 70%, in the first half of 2012 decreased 35%, 10% in the second half year.

A company to survive the most key is trust and reputation, a project, how can you convince the parties that in five years, ten years, the life cycle of twenty-five years, let a person feel your company will also exist, it is very difficult.

Industry some people said, sometimes wrong, often even couldn't find a person, or because the company collapse, or because the head of job-hopping, lawsuits have many questions, no doubt increased the operational risk of power converter.

If there is no stable maintenance support, part of the project will be after the meeting with infinite.

Here might as well draw lessons from the experience of the dc to ac power inverter, enterprise if can with large company have good credit records, or mature corporate partners, can reduce risk.

Selection of third party insurance company, the plant investors can avoid risks to some extent.

At home there is no power station and insurance company cooperation case, there was a lot of plants have frequent contact and insurance company, said an official with a feasible cooperation pattern, is expected in the near future, the insurance company will step in grid tie inverter, the protection of the rights of owners and power plant related beneficiaries.

Fifth, power grid matching problems.

Photovoltaic power station is the biggest problem to some extent, access to the Internet problem, power networks also have a lot of problems exist.

A senior plant say: now the most worry about electricity, not electricity, but rather, in the summer noon 11 a.m. to 2 ~ 3 PM, limit the photovoltaic (pv) power generation.

Cross-examine reason, or network problems, because noon peak power, if the voltage is too big, will lead to power grid can't afford to, lead to broken network.

Faces the second question is, big five power group willing to photovoltaic (pv) power, willing to spend how many money to buy once electricity, which is directly related to plant a lot of investment in operating profits.

Sheng power converter CEO SheHaiFeng told the China electronics news reporter, "because any one industry, real after entering mature period, who master and terminal customers, who can control market and voice, photovoltaic (pv) industry."

The German government took 10 years to cultivate the market, which is mainly composed of photovoltaic (pv) encourage people to accept a new energy source, and the Chinese government since 2009, the policy of "golden sun" but less than 4 years.

"China's DC TO AC policy needs to be continuously detailed, simplification, rationalization."

Hui's solar energy marketing manager Yuan Quan said in an interview with reporters, "say so, China's photovoltaic B2C time had really come."

Yuan Quan said, on the one hand, a series of favorable policies for rapid expanding domestic pv market, promote grid tie inverter market is helpful to B2C era.

Currently existing around the personal family rooftop photovoltaic power station connected to the grid and smooth running successfully, this is the pv market towards B2C age positive signals and good start.

On the other hand, although its New Deal through the interconnection bottleneck, but the examination and approval of the ministry of finance and national development and reform commission and subsidies has yet to form a complete set of rules to follow up, is of great importance to keep up with the "final step".

To this end, the reporter calculated brushstroke zhang. Beijing's first family photovoltaic power station users spend 30000 yuan, in his villa on the installed capacity of 3 mw photovoltaic power station.

If according to the 0.4 yuan/KWH of desulfurization of coal price sell electricity to power department, 20 years to recover the cost; If according to the 1 yuan/KWH of feed-in tariff calculation, benchmarking is only eight years.

Relatively light v product life of 25 years, considering the future of government subsidies, 8 years to recover costs or attractive.

However, to get 1 yuan/KWH a feed-in tariff, power plant must pass through the national development and reform commission for approval.

And apply for approval need to class a qualifications of engineering consultancy for the project application report, the preparation need to urban planning, environmental assessment, land approval report, these costs will be as high as hundreds of thousands of yuan.

So high fees consumers cannot accept obviously let ordinary family, subsidy policy needs to be refined, simplification, rationalization of urgency.

Ministry of science and power converter over the years has been actively promote solar and other key technology research and development in the field of new energy and industrial development, around the pv cell materials, all kinds of photovoltaic cells, battery production equipment and technology, grid photovoltaic power station, and key equipment, etc, a series of major deployment, key projects, has made a series of significant scientific research achievements and successful industrialization. , vice minister of science and technology, said cao jianlin will rely on technological innovation and scale application support industry, rapid and sound development, comprehensively enhance our capacity for independent innovation of photovoltaic industry in our country, accelerate the solar energy utilization technology in China reached the world advanced level, strive for solar power generation cost reduction within five years to the preliminary have the compete with traditional energy such as thermal power, photovoltaic power generation "parity" online as soon as possible.

As a key battleground of grid tie inverter, our country key solar photovoltaic building application.

Launched in 2009 solar roofs plan ", has supported the two batches of 2 years, 210 projects, with a total installed capacity of 180 megawatts.

By organizing demonstrations, in promoting industrial development, activate the domestic market supply and demand, improving pure sine wave inverter building integrated aspects has obtained the good effect.

"More major, photoelectric building market potential is very huge in China, if 10% of the roof using photovoltaic products, can be one of the three gorges power station."

Qiu baoxing, a deputy minister of housing and urban-rural development, said the next step to do a good job of photovoltaic building application demonstration to organize the implementation, we will further improve the photoelectric application technical standard system construction, public application in photoelectric building micro power grid technology demonstration, support the development of green building.

To solve the problem grid-connected photovoltaic (pv), state grid company to fully support the development of new energy and distributed energy access, in the power grid construction, grid management, project demonstration, the respect such as technology research has conducted a series of work.

ShuaiJun state grid corporation deputy general manager said, will further standardize and simplify the process of interconnection, perfect the relevant technical standards and management system, online service for the project units promptly; Implementation of demonstration projects for spontaneous use policy, the surplus of electricity by the state for approval of the local desulfurization coal-fired units a feed-in tariff for benchmarking a full takeover.

"China electronics news" : a cluster of policy support an investment boom of power converter, component manufacturers are downstream power plant market, temporarily reduce the stress of parts inventory.

But we also know that, need inverter, cable, power plant construction of auxiliary equipment such as borders, it is a big investment, and photovoltaic power plant development, collection speed is more slow than manufacturing operations, enterprises will face more risks.

The current situation, to enter and have access to the grid tie inverter market pv enterprises go from here?

Wang Bohua: in order to meet the needs of industrial development, improve enterprise competitiveness, some photovoltaic enterprise business scope gradually from the previous battery components manufacturing to downstream systems integration even power plant operation to expand.

On the one hand trying to kickstart their PV inverter construction components sales; Plans through diversification on the other hand, in power plant investment and operations in order to get higher yields.

At the same time, large power generation group in order to control product quality and cost, have also started to dabble in different degrees in the battery manufacturing.

Such as guodian and CLP vote from silicon has been involved in expected battery components manufacturing, datang, huaneng, and huadian brewing into photovoltaic battery manufacturing, it certainly will further intensifies the domestic pv market competitive pressure.

At present, the trend of the development of the downstream industry obviously, component manufacturing enterprise through the development of the power station to drive the business development.

In addition to economic benefits, it also can make the enterprise know more about your product, found and which aspects need to optimize and improve.

But as a producer, or should be preferred to do business, in every link of production and research and development, on the basis of careful and orderly into the application market.

Qian Jing: currently, as the upstream pv manufacturing the serious oversupply of capacity, enterprise began to enter into the downstream application market, that is a kind of photovoltaic industry.
