Before 2010Manila escort, single crystal silicon wafers were mainly small-sized silicon wafers with a side distance of 125mm (silicon rod straight f164mm), and there are a large number of silicon wafers with a side distance of 156mm (f200mm). After 2010, the proportion of 156mm silicon wafers became increasingly large and became the mainstream in the industry. The 125mm P-type silicon wafers were basically cut around 2014, and the basics were only used for some IBC batteries and Escort manilaHIT battery components. At the end of 2013, five companies, Longi, Zhongli, Jinglong, Sunlight Power and Kamdank, jointly released the M1 (156.75-f205mm) and M2 (156.75-f210mm) silicon wafer standards. Without changing the size of the component, M2 increased the power of the component by more than 5Wp by calculating the silicon single area (calculating 2.2%), and agility has become the mainstream in the industry and stabilized. During the year, there were also a large number of silicon wafers with M4 specifications (161.7-f211mm) in the market, with a 5.7% increase in surface ratio of M2, and the products are mainly N-type dual-surface components.

By the second half of 2018, due to market competition, many companies have once again turned their attention to silicon wafers, hoping to gain product competition by increasing the power of silicon wafer size and components. One kind of thinking is to follow the M2 development thinking, without improving the component size, and continue to improve the silicon wafer edge distance. The sizes considered include 157, 157.25, 157.4mm, etc., but the power gain is more unlimited. On the other hand, the addition of Escort manila requests for production accuracy and can also affect certified compatibility (such as crawling power that cannot meet UL. daddydistance request). Another type of thinking is to continue the components along the 125mm to 156mm, such as a chamfered silicon wafer or all-round sheet (f223mm) of 158.75mm specification, which increases the silicon single by 3% to make Sugar babyThe power of 60-piece battery components has increased by nearly 10Wp; at the same time, some N-type component manufacturing companies have selected M4 silicon wafers with a 161.7mm edge spacing; others are preparing to release 166mm edge spacing silicon wafers.

The silicon wafer size is 158.75mm, more affordable?

Evolutionary Fund Rain Treatment Fund believes in his article that the advantages of silicon wafers with a specification of 158.75mm are obvious.

The silicon wafer with a length of 1.158.75mm is only 2mm longer than the silicon wafer with a current 156.75mm. All existing production capacity can be upgraded through technical reforms, and the technical transformation is fair and affordable. It is clear that the price of 100MW of technical transformation can also be kept within 400,000 yuan.

2.158.75mm long square single crystal silicon wafer (Sugar baby25,197m㎡) In her dream, she is a small supporting role in the book. She sat on the far right of the stage and compared the current M2 standard single crystal silicon single (24,429 and participants – answered the question, and then made a definite m㎡ for their answers) of 3.14%. With the current M2 size, it is expected that the mainstream power can reach 315 by the end of 2019. href=”https://philippines-sugar.net/”>Sugar baby~320W, then the battery unit increased by 3.14%, and the maximum power generated by the calculation can reach 10.05W, which is equivalent to the two power files. 158.75mm can make the mainstream power of 60-type single crystal PERC components close to or even reach 330W by the end of 2019.

The size of the photovoltaic component after the battery pack of 3.158.75mm is only 1.4cm long, which is a 1% increase in percentage measurement. Since 160μm thinner silicon wafers and thinner EVA corresponding to them are used, although the photovoltaic component area increases by 1%, the overall total component volume remains unchanged.

4. The cost of producing 158.75mm square single crystal silicon wafer pulling crystal ring and silicon material ring has increased, but the cost of decreasing the thickness of the silicon wafer from 180μm to 160μm is more significant. According to comprehensive calculations, the cost of producing square single crystal silicon wafers with a thickness of 158.75mm and 160μm will be 8 cents lower than that of M2 silicon rods with a thickness of 180μm.

Online, 158.75The square single crystal silicon wafer with mm length, 160μm thickness, 224.5mm opposite angle line has many advantages in production cost reduction, photovoltaic component parts, two files of power, and high battery terminal reception.

QingqingSugar daddyChu Baoli Coxin’s calcification is based on the square size of 158.75mm, while the traditional specification polycrystalline silicon wafer must be fully upgraded to 158.75mm.

Can the “micro-innovation” 158.75mm all-round single crystal become the mainstream or industry standard in the industry? There was also a different sound.

Another size, which is the best 166mm chamfer?

Escort knows that the important reason for the development of silicon wafers is the expansion and dispersion of batteries. In the scenario where the silicon wafers are as large as possible, single crystal silicon wafers with certain chamfers should have certain advantages over all-round single crystal silicon wafers. The 166mm chamfer is a good choice.

From the decline of the electric cost, which size is more suitable?

1. Comparison of components using 125mm batteries in the late stage and components using 156mm batteries

In 2012, there were still components made of 125mm single crystal silicon wafers on the market at that time. The size of the photovoltaic components using 72 batteries (6′12) was 1580′808mm, and the power of the single crystal components was about 205Wp; during the same period, the power of the 156mm 60 batteries was about 260W, and the size was 1650′991mm. The circuit voltages of the two components are 45.92V and 38.24V respectively. They are larger in series with the components of 156mm battery plates. Considering the power of a single block using a 156mm battery assembly, the image of “Book Beauty” is more powerful. As one of the background figures, Ye Qiuguan is the highest. Pinay escort is a component with a total power of a single string component that is significantly higher than 125mm silicon wafer. The bracket that carries a single string component can be made more powerful. The bracket and foundation cost can be easily saved by leveling to each Wp of the bracket and the base cost. The manual task effect of the installation of photovoltaic components and brackets is also obtained due to the increase in the power of a single block photovoltaic component, the usage of photovoltaic cables is reduced, and the amount of ground plates is occupied.There will be a little savings.

This Pinay escort cannot be calculated through simple linear conversion, and the demand tree-standard array model is analyzed in detail and is simple to measure based on the 2012 capital model. baby results are as follows (the project is Germu, the same below). 30% of the power brings a BOS related to the power of the photovoltaic component 0.43 yuan per wattage, which is about 16% savings.

Comparison of 2.60 and 72-type photovoltaic components

156(.75)mm battery sheets can also be packaged into 72-piece (6’12) batteries to further improve the assembly power, Sugar daddyThe increase in battery quantity has caused the increase in circuit voltage and the number of series connections to decrease. The power of the series components remains unchanged. However, for the common two-row assembly of components, the bracket slightly extends the length of the inclined beam to support 72 battery components, and the bracket cost has slightly decreased. This situation is more obvious for the single axle bracket with higher capital, so the single axle tracking system is usually It is used with 72-piece battery components; on the other hand, the manual task of installing components and brackets has also decreased due to power loss. The Chinese market’s preference for 60-piece battery components is the habitual problem. New markets such as South Korea, Southeast Asia, and India in Asia all use 72-piece battery components to reduce system costs in large-scale power stations and industrial and commercial distributed power stations.

The 72-piece battery assembly can bring about 1 point/Wp savings in terms of brackets, cables, transfer boxes, etc. In terms of installation, it can simply calculate based on the number of components, which can bring about 2.7 points/Wp savings. The comprehensive can bring 3.7 points/Wp BOS money savings on the system.

3Sugar daddy. Comparison of multi-silicon wafer (166mm) components and existing photovoltaic components

Sugar daddy started to appear in 2018. There are two ways to increase the number of battery cells or use silicon wafers as large numbers.. The number of battery cells can be improved from 72 to 78 (+8.3%), and the size of silicon wafers can be improved to M4 (161.7mm, +5.7%) or even 166mm (about +12%). According to the changes in 60 to 72 batteries, it can be found t TC:

After nearly two years of announcing his participation in the “coal dumping” ranks, Sugar baby Germany finally took a solid step. Reuters reported that on December 1, the German Power Network Governance Bureau publicly stated that it has confirmed that the list of the first batch of large coal-fired power plants in the country to be suspended will begin its official start at the age of the year. “Resolution of large coal-fired electric factories. This is another breakthrough progress in Germany’s journey to “demolition of coal” after officially closing the last hard coal mine. As early as 2019, Germany had high performance that it would officially become a member of the “coal discharge” team. In the future, coal-fired power plants will be slowly shut down, and the last time it was “coal discharge” was finally “swept away” just before 2038. But since then, Germany’s “broken coal” path has been reversed. Since this year, the first batch of large-scale coal-fired coal-fired Song Weibo has been promoted due to the new crown pneumonia epidemic. The factory’s shutdown plan was launched, and then in June, the company launched a coal-fired electric factory in DaSugar daddytteln-4Sugar daddytteln-4Sugar baby‘s coal-fired electric factory. For a while, the industry has caused widespread doubts about its innocence for “sweeping coal”.

For this,Reuters wrote an article titled Sugar baby, which started the first coal-fired power plant, Escort manila, which is a desperate step for Germany to carry out the “End of Fossil Fuel Age” undertaking.

It is clear that the total coal-fired power plant installed in Germany is about 4.8 GW. The German Federal Power Network Governance Agency and Manila escort did not reveal the specific list of these coal-fired electric factories. The young actress is the heroine. The heroine in the story shows that these electric factories are now selling electricity to German public utility companies Laiyin Group, Uniper, etc. in the Sugar baby. According to the planning, coal-fired power plants that have been closed will no longer participate in the German power market from January to January, and will be officially closed before July to be converted to reserve power.

In addition to Sugar daddy, the German Federal Power Network Governance Agency also stated that the operators of the above-mentioned closed coal-fired power plants will receive a “Stop Replenishment Stick” and the Sugar baby is 66,000 EUR/MW. To this end, the total amount of supplementary supplements for coal-fired power plants in this link will reach 31.7 billion euros.

It is believed that as Europe’s largest economy, Germany is accelerating its promotion of dynamic transformation by “not counting capital”. Today, coal and electricity account for the total supply of German electricity1/3 of the volume. The road to “coal dumpingEscort” under the comfort of high-enhancing submission may face the certain economic pressure in Germany.

In response to this, the German Federal Power Network Governance Bureau responded that it should not limit its vision to fund investment, but rather “find the balance between reduction and income.” At the same time, according to the current planning, the theme of coal-fired power plants that were closed by Escort before 2027: Keep the mind positive and shine brightly. Enjoy the supplementary sticker, and the “close the supplementary sticker” will be cancelled after 2027.
