Quality is the life of the photovoltaic industry

Sponsored by the China Machinery Industry Federation 2014 China PV power plant performance testing and quality assessment technology seminar on October 31, 2014 in Beijing China Science and Technology Hall held, the meeting "to implement the policy approach, the selection of technical products to ensure the quality of power plants "As the theme. And actively respond to the power station quality problems for the development of the industry challenges, participate in "photovoltaic power plant performance testing and quality assessment of technical specifications," the views of the work, implement the "norms" of the requirements, the following is the national response to climate research and international Li Junfeng, director of the cooperation center, his speech is the theme of "quality is the life of the photovoltaic industry"
Just heard Dr. Zou Xinjing talked about the quality of photovoltaic power plant testing some of the standards and we had a discussion and exchange. I am not engaged in technology, I just from the policy point of view the importance of quality. I used to talk about wind power, 06,07 years when the wind power to 10 million kilowatts, when we wind power installed in the past only tens of thousands of kilowatts, hundreds of thousands of kilowatts when all the problems can be ignored. A child in adolescence anyway is very cute, but to more than 10 million kilowatts can no longer be a child, you are very important power generation. We PV more time on the wind power, starting in 2009, now more than 5 years now more than 60 million kilowatts, a shorter period of time through the puberty, as the main power generation. This year the whole national power installed capacity of about 80 million kilowatts, wind power 20 million, photovoltaic power generation 1,300,14 million kilowatts, plus more than 20 million hydropower, more than the conventional fossil energy. Under such conditions, our quality assurance, electricity is particularly important.
Conventional power plants are not the same as our wind power and photovoltaic power generation, not so complicated. Our coal-fired power stations and gas-fired power stations are standardized. Coal-fired power plants, for example, in the past 50,000 kilowatts, 300,000 kilowatts, 600,000 kilowatts, 900,000 kilowatts are standardized. As long as the installation of this unit, my efficiency, power generation on the set, are fixed. In fact, the power station is extremely simple, we are very demanding on the grid, in fact, the grid is not harsh, very simple, that is, a few simple indicators, your voltage, your cycle, your power generation, your scheduling, Several things to solve the problem.
Our PV power plant in the future may be like this, our power generation forecast is how much, our power error is how much we can be scheduled, which can not be scheduled. To solve these problems is that we are now facing some of the special problems of photovoltaic power plants. This requires us to include a very clear technical specification on our components, including our panels, including our inverters, controllers, and even the arrangement of our arrays. There will not be similar to this problem, and now we can not do, but slowly may have to solve this problem. Dr. Zou talked about your battery sheet efficiency is high, the efficiency is low to pick you out. Why do we say that the efficiency of the panels are the same? Now from the manufacturing level, you should not be a substation, are polysilicon 18, some 16. You supply a power station should be consistent, not a power station has seven or eight things. So that will engage in a large power will laugh, you net mess, a power station board is not the same. We dumplings look like, can not say that a look like a battery, an inverter look like a power station seven seven eight eight.
For example, we first bid for the photovoltaic power plant, Zhou Huang is still in the energy bureau, we in Dunhuang, we took the power station after the polysilicon, monocrystalline silicon, film, the results of seven or eight technologies are there, what mess Something, what do you give us the same thing? Regulate the importance of why to regulate the importance of it. Because we have a lot of photovoltaic problems, from the day it was born with high-tech self. I am the size of this technology after the reduction of how much of my efficiency every year, every day to engage in high technology. For power plants do not care about these things, you say you are high-tech, high efficiency, high technology can, I see is the power generation. You have high technology, you get the Nobel Prize, you power the power station every year 10 million kWh, I am not won the Nobel Prize, I power station this year, 11 million kWh, better than you. We have a variety of new technology to get a lot, you say that the eye to attract the media, that you can innovate. But for a power station, for an investor does not matter, I no matter how you are, you give me electricity can be, and my return on investment is less. I do not talk about so many stories to listen to, and now the story of the times have passed, power generation is now the most important thing. We are not adolescence, do not need so many stories. If the story is used for two reasons, the first we do not know the PV, the importance of photovoltaic and rapid decline, etc., and now we have a very low cost, has been rapidly declining. According to the current cost, generally not more than ten thousand dollars a kilowatt. The future seven or eight thousand dollars a kilowatt, are no problem.
There is a friend told me that my future photovoltaic power generation can drop 2 cents below, I said why should drop 2 cents below. We all know that oil production costs in the Middle East about three to five dollars, the global cost is ten dollars, he sold $ 100 when we feel very normal. He now dropped to $ 84, the world said oil prices plummeted. He is ten times the profit, we say oil prices plummeted. You are here to engage in photovoltaic, many companies here, you dare to say that your battery plate made out of your profit ten times it. Why can you drop 2 cents to Bluff, you drop 2 cents when you sell 5 cents and no problem, not sin. Why is this? This is the industrys long-term development of the most fundamental thing, this is my second point. Our equipment manufacturing industry, photovoltaic things are the same with the wind power, by equipment to make money, good equipment can make money, poor equipment can not make money. Need to have reliable quality stable operation for more than 20 years.
Recently there is a big lead I said you said every day that solar energy and wind energy cheap, when your solar power and my coal and electricity, I said do not worry. If Chinas total photovoltaic power generation in the country if the total amount of electricity accounted for half of the time to reach this target, done ten years my PV cost can be zero. We invest back, your PV is really 25 years of life time. We now have all the return on investment is 8 years to 10 years. Ten years later I basically is zero cost, we PV cost is very low, in your investment costs accounted for very low. The key quality is our life, really you can not do 25 years, 30 years.
I visited the first generation of batteries in Beijing in a decade ago. The first generation of batteries in the late 1960s and early 1970s looked so hard that they were still in stable power generation. Now many of Chinas power plants in the early 70s now fast 40 years, but also in the stable power generation. We do 25 years of stable power generation, we seriously do is no problem. But we are now a lot of problems, uneven quality, uneven raw materials. Because we blindly pursue low cost.
We want to work together with the machinery industry to engage in a thing, I am now the General Assembly will tell such a story. China is now talking about the rule of law, the general secretary of good law good governance, bidding method, the lowest bid. Resulting in our equipment manufacturing is not the lowest, only lower, lower than once lower. This reason is particularly simple, we all know, because our bank interest rate is the state, we loan you get the money is 6 points or 5 points This is the state regulations. You and the bank is very familiar, he gave you a loan is very familiar. We are fellow, country regulations 6, I give you 3, it is impossible. The rate of return of our developers is also the provisions of the SASAC on the assessment of all the central enterprises, 8,10,12 several rate of return is fixed. Only pressure equipment, equipment never said the price of equipment you have to have much profit, no such provisions. Any tender there is no standard that you sell the price can be to ensure that your profit margins must be how much. You are cheap and reasonable, we do not have such a provision. Never guarantee the profit margins of equipment is how much, this led to our equipment, the rapid decline in profit margins. Only from the quality to do such a thing.
Recently, the PV industry association they announced a number that they are now built inside the power plant about 1/3 of the quality is unqualified. There are some of the original provisions of the battery 25 years decay how much, now is 3 years has been decayed 25 years should be attenuation of things. Even when the attenuation of more than 30%, some banks take this thing, I said do not take this thing. If it is really photovoltaic, crystal silicon cells, in strict accordance with the provisions of quality, standards to produce, then there will never be a year of 30% efficiency of the situation. Certainly is the cost, not a quality problem, but an economic crime, or even a criminal offense, not a simple quality problem. You from the quality of the problem to solve the original 20 years of attenuation of 2%, 3%, you in a year which decay 30% of such things out of quality testing can not be resolved. Such a problem should be resolved from another aspect. This problem has become our PV industry, the black sheep, and now many people say that we hate this thing, and can not find a way to decide. Now just to find them Zou teacher they engage in this set of power plant assessment and testing. I am not saying that this assessment and testing is not important, it is important, but he and our national approval of the project is the same.
In the past I went to the Development and Reform Commission, my leadership is the original Sinopec CEO, is the vice chairman of the CPPCC National Committee, he asked me this sentence, the state approved the project was about 70% loss, the late 80s, the early 90s state-owned enterprises Bitter, we approved the project 70% is a loss, not approved will not be 100% loss in the question of this matter. You detect the power station is qualified, can not send electricity useful? Detection I failed, I power well, what is the problem. This thing by the detection of no use, the key is all the choice, if it is a good thing is no problem, the choice is not good, there is still a problem detection. Detection is no problem, but also a problem. The final result, investors Ye Hao, power grid Ye Hao, investors are more simple, is a power generation. Because the price is fixed, you have power, I have a return. Power grid that can be extended, your power generation, your frequency, your price stability, enough, enough to. I do not so much, engage in so much to do, security problems your own thing, you will not pick up the ground. We can not take you as a child, what things are in charge of you, photovoltaic power generation has been through the puberty. You are inside the power generation this year is more than 10 million kilowatts, to thirteen five times when the annual photovoltaic power generation to more than 20 million kilowatts. We must follow the standard technical requirements of their own, not someone else to check, supervise you. We like the big power station, I like this, ten megawatts power station is like this, monocrystalline silicon is the efficiency of polysilicon is this efficiency, the film is the efficiency of that. In the same place, unlike coal-fired power plants, coal is the same in any place. We are in different places, the sun is not the same, so it is not the same. But the big thing should be no essential difference, if we are still to the thirteen five of our power station or so strange, all kinds of things have, then there is a problem. We have to slowly solve the problem of consistency and consistency of our quality standards. Now we are not eager to reduce the downgrade, not eager to technological innovation, but a stable, reliable and consistent products for our large-scale power plant construction to provide standardized equipment. This is what we need in this industry, thank you.
