Photovoltaic (pv) giant snap size silicon war really the bigger the better?

Central stake in the release of 12 inches large diamond wire cutting solar monocrystalline silicon square piece, side length 210 mm, diagonal 295 mm, surface area compared with 80 M2 of silicon increased. 5%, compared with the M6 silicon increased 61%. Central stake Shen Haoping chairman said that the future will be positive and industrial chain each link partners to strengthen cooperation and jointly create technology cost better, stronger, more efficient new technology platform. Solar photovoltaic (pv) net news: monocrystalline silicon slice of the first, second overlord has been pushing for big size of silicon products, zhejiang new heat treatment for which a size to be able to win in the competition from? On August 2, central stake has passed the announcement released the news of the release. This requires a comb from the pull rod section, batteries, components used in three stages: the main production equipment, especially after the two links of equipment modification. Therefore, it is for the M12 wait. In accordance with the information provided by central stake, M12 size p-type PERC 60 pieces of half a piece of component conversion efficiency can reach more than 20%, superposition of efficient battery, power can break 610 w.

central stake also said that the release of the M12 large size wafer, broke 12 years ago by the same for industry to lay the 8 inches of M2 silicon technology framework. ' (pv) of the world' this is a comprehensive system to introduce the development of photovoltaic (pv) in the past, present and future the sum of the corpus, wide-ranging, can meet the needs of different readers. On the same day, the company shares harden, closed at 11. 33 yuan. As the world's single crystal city for the first photovoltaic manufacturing giant, longji shares the M6 monocrystalline silicon slice of the Hi - at the moment MO 4 components, the intention of orders for more than 2 gw worldwide. The company said, the future after the five phase of the project construction, production capacity will break through 56 gw, global market share will reach 45%. Solar photovoltaic (pv) network statement: this information is reproduced from the media or other Internet web site, network cooperation photovoltaic solar energy network published the article for the purpose of the information, does not mean that agree with his point of view or confirm its description. This is the biggest silicon photovoltaic industry with size. A line of photovoltaic solar energy modules corporate executives to reporters interface, downstream ( Batteries, components, power plant) If necessary M12 size, adjustment of production line will be very big, the cost of solar water will not be low, and the existing equipment manufacturer has not yet developed solutions. The article content is for reference only. The longji shares ( 601012. SH) After pushing large size M6 wafers, another single crystal giant Tianjin Zhonghuan Semiconductor Co. , Ltd. ( Hereinafter referred to as central stake, 002119. SZ） Unwilling to lag behind, steam generator principle followed by the launch of the photovoltaic maximum size of silicon wafer in history. “ Continue to increase the size of silicon wafer, need to purchase some devices, the falling cost of increasing the size will be offset by the increased cost of buying new equipment. As the upper part of pv modules production, silicon wafers in the component costs accounted for 30% 40%. Assistant general manager of the central stake hai peng on interface news, said the 2 - in the future There will be 20-3 years, the company 30 gw of new domestic trades. the line size, the existing production wafer production line is to keep the original size. Increased restrictions on the size of silicon wafer, lies in the compatibility of existing equipment.

　　” Another photovoltaic enterprise executives said the monitoring project installation component size is too large will also increase the risk of mechanical load and cracked, battery the fragment rate and yield will also face the challenge, at the same time, solar heat storage tank can't support basic trend of wafer. In general, the principle of silicon wafer size upgrade steam generator will increase product by light area, improve power and reduce the manufacturing cost per watt, but also can increase the weight. On August 16, central stake in tianjin at a new conference, launched 12 inches large wafers & other; Kuafu & throughout; M12 series products, as well as the M10, solar heat storage tank M9 two iterative product. As of June this year, central stake monocrystalline silicon chip production capacity has reached 30 gw, a global market share is about 30%. “ For system side, the size and weight of the component has a limit, based on the weight of the M12 so-called 600 w components should have 45 kg, installation costs don't '. Zhejiang heat treatment more than hiring the personage inside course of study on interface latest news reporter said that central stake in the launch of the M12 size of silicon product is still in the conceptual phase, still need to solve the problem, distance to the market truly still have a long time. Monitoring project installation in this paper, not only including the 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, the conference today, central co said in a statement, new product theory to measure will reduce the KWH cost more than 6%, the new product or reshape photovoltaic monocrystalline silicon slice segment in the industry competition. Longji shares its longji le leaf chairman assistant inger ridderstolpe to reporters interface, the company plans to reform the existing cell, component production line, in the end of next year, basic transformation into the production line is suitable for the M6 dimension, apply directly to the new production line is the size. ” He said. Monocrystalline silicon slice of the first, second overlord silicon products, has been pushing for big size represents the size of the war between silicon enterprises has begun, but exactly what kind of size can be from race wins, still need to market test. Solar energy research institute of Shanghai jiao tong university wen-zhong shen has said that solar energy engineering co. , 166 mm M6 size has reached some devices allow the limit, in a short period of time, size of silicon wafer is difficult to improve, it will become the standard for a long time limit.
