Recently, the national energy administration in the printing is put forward in the 2017 energy work guidance, we will continue to implement the photovoltaic "leader" action, fully give play to the role of market mechanism, promote power generation costs down.

Natural resources in gansu province, deputy director of the institute of account, told reporters that this year and during the whole "much starker choices-and graver consequences-in", pv's main task is to promote technological progress, reduce the cost of power generation to achieve parity with the Internet. However, photovoltaic power station subsidies are gradually on the ground, the pv KWH cost reduction pressure is gradually increased. "Leader" is the national energy administration through the market behavior of China pv industry development a way, the best technological progress in the main manufacturing development. Therefore, we will continue to implement the "leading" plan to reduce cost of photovoltaic power generation has a very important role.

So, in the moment the from what respect really driving photovoltaic power generation costs down?

Good play a leading role of "leader" plan

According to reporter understanding, the photovoltaic industry in China over the past decade to authors mainly by three aspects: one is the experience curve, study abroad; Secondly, the scale effect, the cost drops rapidly; 3 it is technology innovation. The utility of the experience curve is very low, the scale effect of authors have also been close to the "floor", continuous technological innovation has become the present the development of photovoltaic industry upgrading, the most effective means to the realization of ultimate parity on the Internet. Photovoltaic (pv) "leader" plan for more than a year, high efficient and reliable products quickly to speed up the popularization and promotion. The guiding role of the advanced technology and photovoltaic product efficiency is very obvious.

Journalists access to a copy of the shanxi datong coal mining subsidence area photovoltaic demonstration base of national advanced technology project investment documents "in 2015, the indicators have strict rules on construction base for photovoltaic power station, such as photovoltaic power station first year system efficiency of no less than 81%; Single crystal components efficiency more than 17%, polycrystalline silicon photovoltaic module conversion efficiency is not lower than 16.5%; Inverter with zero voltage through the function, the highest conversion efficiency of no less than 99%, the comprehensive efficiency of no less than 98.2%, etc. Obviously, part of the pv modules low-tech products and strength is not strong of small and medium-sized enterprises will be difficult to participate in the plan.

As China's first "leader" plan project - datong coal mining subsidence area national advanced photovoltaic technology demonstration base of the first phase has been connected to the grid at the end of June last year.

It is understood that the project using the 1.016 million mw photovoltaic modules, including monocrystalline silicon components of 609000 kw, accounted for 60%. At present several provinces across the country had been launched the "leader" base project bidding project, bidding for successful companies in the industry generally have higher visibility, and strong technical strength.

If successfully won the bid last year "leader" of xin new energy base project, yingli energy companies such as is the best example.

In addition, at present, trina solar, its holdings, jin can science and technology, RON artest, crystal energy, and many other powerful photovoltaic pv enterprises are stepping into the "leader" plan.

According to the relevant department, compared with the conventional component, "leader" advanced technology components in almost no increase in the cost of implementation capacity per unit area by 5% ~ 8% improvement, to promote as a decline in the cost of photovoltaic power generation has obvious effect. Today, under the leading of "leader", "leader" base project not only has clear standards to the advanced technology and conversion efficiency, other pv projects also began to "leader". Last year, for example, domestic investors more mainstream power station in the process of large centralized bidding, general project equipment products also need to satisfy the standard of "leader" plan efficiency.

Account told reporters that this year the state will also stage the upgrade version of the "leader" plan, will pay more attention to technology, relevant departments should give full play to the "leader" plan technology leading role, make more new technology has been applied in the field of photovoltaic (pv), which will effectively promote as a decline in the cost of photovoltaic power generation.

Full implementation of bidding online

On May 30, 2016, the national development and reform commission, energy bureau jointly issued a "about perfecting the photovoltaic scale management and implementation of competitive way guidance of configuration items. Nowadays, under the guidance, fully give play to the role of market mechanism, the development potential of the photovoltaic industry to activate. Photovoltaic "leader" in the project bidding on performance is particularly obvious.

Learned, based on the above guidelines, 2016 photovoltaic "leader" specially added for online content. Including 10 last year, in Inner Mongolia wuhai "leader" in project bidding, yingli energy to 0.45 yuan/KWH of ultra-low prices successful bid, the price is lower than the current civil electricity prices, the industry were shocked. Seems to let people see the pv parity the dawn of the Internet.

According to participate in wuhai photovoltaic "leader" of the project bidding related enterprise said, some enterprises have dared to "price competition", the main reason is the price of photovoltaic modules in falling. Another reason is the "leader" priority access to the Internet, priority project bidding enterprise can get subsidies, therefore, in this case, have better payment terms, to enable the best management team, the use of the best capital resources, make similar to the price of 0.45 yuan/KWH also small profit can be realized.

Photovoltaic market around the world, some countries through the bidding the Internet also makes photovoltaic implements a sharp fall in price. In 2016, for example, in the united Arab emirates pv projects bidding, the lowest price of 2.42 cents/KWH. In India recently a photovoltaic project bidding, the lowest price of only 2.99 cents/KWH.

Account tells a reporter, for access to the Internet is a process for the development of photovoltaic industry, is also a "leader" project bidding a means, through the competition can reshuffle, do not have technical advantages of enterprises will withdraw from the competition. Purpose is to make the photovoltaic enterprises to speed up the pace of technological innovation, improve the conversion efficiency, reduce the degree of electricity costs.

National energy administration of new energy and renewable energy, deputy researcher XingYiTeng said yesterday, in 2016, mainly in eight "leader" base adopts the public tender bidding online mode, the average program than the local solar feed-in tariff benchmarking down 2 cents, is expected to save a subsidy of 1.5 billion yuan. In 2016 did not online on common project bidding mode, in order to help pick up the photovoltaic industry to reduce costs, for ordinary projects this year will also take the bidding model online.

Optimization of power plant planning and design

"At the same time of feed-in tariff cuts, ordinary photovoltaic power station project will also be fully open bidding mechanism, as a result, photovoltaic power station will gradually into the era of" small profit ". In the present photovoltaic application mode diversification development and photovoltaic manufacturing technology level under the premise of rapid ascension, how to strengthen construction of photovoltaic power station in front of the fine design and equipment selection, to further reduce the degree of photovoltaic electricity cost is more and more important." Industry insiders said to reporters.

Survey of northwest China in turbine design and research institute in photoelectric branch director Mr Xiao recently held the second symposium on photovoltaic power plant design and equipment selection, said by refinement, customized design rules, environment friendly, scenery and ecological benefit, economic benefit and so on transboundary into the planning idea of the photovoltaic power station project, puts forward a new design concept for the photovoltaic power station.

Want to refinement, customized design, photovoltaic power plant at the time of planning and site selection, you need to consider the comprehensive utilization of land resources. Farmers can be used, for example, complementary, fishing light complementary, livestock light complementary form such as building photovoltaic power station, it can turn the traditional industry and pv of the benefits of a complementary and ascension, finally realizes the ecological benefit and economic benefit of double harvest.

In addition, in view of the complex terrain of the photovoltaic power station design, the three gorges qi-ren wu, chief engineer of new energy in the conference, said: "we should for photovoltaic array shape Angle and set a detailed examination, selected slope, towards is advantageous to the photovoltaic power station layout area, to avoid tall buildings around you, on the premise of land conditions allow, comprehensive analysis of increasing components support unit front row spacing, prolonged power." Its also told reporters that at present the space of photovoltaic power station design can be optimized and lots more. Increase of installed capacity of photovoltaic modules, for example, can increase capacity, reduce the number of inverter, can save the cost, essence is to improve the yield of plant; Cable loss and usage, optimization design is the key consideration, usually the laying of the cable quantity, and array configuration, parallel line, topography and the position of inverter room.

In terms of equipment type selection, if use 1500 v dc system, can effectively reduce the dc cable loss, improve the system efficiency. Learned, including golden concord in funing in jiangsu province donggou 30 mw farm's light complementary photovoltaic power station adopted the 1500 v dc system, without any increase in the cost of cable reduces the photovoltaic power station under the condition of dc line loss of about 30%, improve the efficiency of the whole of the photovoltaic power station system by about 0.4%.
