Destroy the value of monocrystalline silicon slice of chamfering how many?1

Solar photovoltaic webex: current M2 monocrystalline silicon chamfering in the area of the silicon area 0. 56%, that said, if we produce monocrystalline silicon slice, but increase of monocrystalline silicon area 0. 56%. Calculate according to the conversion efficiency of solar cell to eliminate this part of the value to bring 1 to 60 version type of component. 8 w of power increases, in this paper to answer this one. The value of 8 w how much?

as always, to answer this question, we need to find the answer to this question of the framework, and then find the answer in the framework of a structured thinking let nature take its course. I have to answer the question today found analysis framework is: the same components area under increasing power equal to the value of the cost price system - Inverter price, this is my latest advances some ideas on simple analysis of the high power component value, so I think it is necessary to put this analytical framework repeat: under the same component area increase the value of the power price cost - equivalent to the system The price of inverter.

: for example, the same component size through the elimination of chamfering bring 1 to 60 version. 8 W of power, a power station project cost system for 5 yuan/W, price of inverter is 0. 2 yuan/W, then eliminate the chamfering value = 1. 8× ( 5 - 0. 2) = 8. 64 yuan.

the component needs to have the same area, land transportation and installation, bracket, cable, such as cost, higher power under the same area of the component part is equivalent to giving peripheral system, which is the core of the high power components premium source. If I the analysis framework is right, then, in turn, the conclusion is: by improving the component area of proportion of power increases not bring component premiums, because from the perspective of terminal station owner, such power increases correspondingly raised a series of related cost and area, natural hard to have a premium component.

I have always been advocates of single crystal, 1 above. 8 w calculated the enormous value of the aesthetic values of the single crystal there is very important, the quantitative value is bad, but it does affect people's choices, in Europe, many customers would rather lose some power to persistent choose black back, behind it is the truth.

we are about to hit the vigorous and a half times, according to a pv information institutions, at the end of the year and a half piece of component production capacity will reach 58 gw, and half a time will magnify chamfering silicon problem:

this is a half piece of component based on M2 wafers, string spacing have very irregular shape. And if you use square monocrystalline silicon chip encapsulation out of half a piece of component, and can completely solve the above problem:

I also learned some friends worry single crystal production capacity brought about by the loss, square monocrystalline silicon wafers need to import more coarse diameter of silicon rods, the resulting productivity losses of 8%, in the face of such concerns I would like to quote a famous saying of Zhong Baoshen chairman as answer: market economy is an economy of excess, excess is the norm of the market economy.

the monocrystalline silicon chip production capacity in the abnormal state, due to excessive heavy industry reshuffle in 2018, this year because of monocrystalline silicon chip is a shortage of capacity, but by 2020 or 2021 at the latest, high quality monocrystalline silicon chip production capacity is greater than the total market demand, again likely when leading monocrystalline silicon chip maker may surprise: square monocrystalline silicon slice is active to promote capacity, the most effective tools for square monocrystalline silicon slice will be at the time of the silicon excess capacity has been fully spread.

'photovoltaic (pv) of the world' this is a comprehensive system to introduce photovoltaic summary of past, present and future of the development of corpus, wide-ranging, and can meet the needs of different readers. This paper not only includes editor Wolfgang & middot; Dr Parr, herself, in its new energy career of more than 50 years, the deep understanding of the development of photovoltaic (pv) and system summary, also include the global photovoltaic industry professionals engaged in new energy or a review of the photovoltaic difficult development,

in addition, the national stadium & other The bird's nest & throughout; And the Olympic central area of photovoltaic power station are also at the beginning of the design, together with the roof ably, become one of important decorative building components. It can be said that the combination of photovoltaic (pv) and building extensive use in the Olympic Games to promote Chinese photovoltaic building integrated ability provides the best practical experience and technical validation.
