As the photovoltaic glass with a thickness of 2.0mm even ≤1.8mmSugar daddyPhotovoltaic glass is slowly maturing, and the problem of “the cost of double-sided components is natural. The dual-surface double-glass components benefit from reducing the application of organic back panels. The fire resistance of the components is high, long-term decay, water vapor resistance, corrosion resistance, fire resistance, sand resistance, wear resistance. The life of the photovoltaic power station has been increased from 25 years to 30 years, and the life of the power station has been increased by one step from the perspective of packaging data to 40 or even 50 years. The photovoltaic power station has been supported from the perspective of packaging data to support the photovoltaic power station from the perspective of packaging data to become a long-term, useful, reliable and value-preserving property. The true comprehensive Percization of the plug-in battery and the natural adaptation of perc batteries to double-side technology and the further improvement of double-side battery technology, in the promising short-term future, the theme of double-sided double-glass group: maintain a positive centripetal and shine. The market share of the package is expected to be rapidly rising, and I call this historical tide as the unorganized era of components. If you are reading this article and also seriously thinking about what we can do under such a tide of the times, then I wish you, you are the tide of the tide of the tide.

1. When the 2.0mm photovoltaic glass that determines the universe, the back of the photovoltaic components for double-sided power generation will be more complex. Currently, double-sided components that use glass as packaging materials mostly use 2.5mm thick photovoltaic glass. From the bottom of the picture, it is indeed difficult to distinguish between photovoltaic glass and bright back panel. If we look far, 2.0mm thick photovoltaic glass will eventually mature. It is just a production and manufacturing problem, and the inherent problem of bright back panels (organic substances) is a problem that originates from the first principles. The problem of production and manufacturing is never a problem with human intelligence, but a problem that comes from the first principles is always a problem, so the “photovoltaic glass VS bright back panel”Sugar daddy is a disputed area.For red-eared problems, we just need to change the dimensions of the problem, and make judgments immediately on the high and low, and solve them immediately on the bad. Regarding photovoltaic glass, I hope that the master will remember a parameter: the corresponding portion of a 3.2mm thickness photovoltaic glass of 125 square meters is just 1 ton, that is, 125㎡ photovoltaic glass (3.2mm thick) = 1t=1000kg. In this way, a double-sided assembly of 2.5mm thickness is 2.5×2=5mm, and the corresponding result is 80㎡. Photovoltaic glass 80㎡ (2.5mm*2 thick) = 1t=1000kg Use 2.0mm× thickness dual-sided components. 100㎡ corresponds to 1 t of photovoltaic glass 100㎡ (2.00mm*2 thick) = 1t=1000kg We calculate the weight of various component types according to the simple correspondence below.
Conclusion: The current 3.2mm-thick 72-type assembly is about 21kg. If the 2.5mm-thick double-sided assembly is used, the weight will reach 27.75kg, and the weight will increase by 6.75kg, which is 32.14% higher than the original portion! If the 2.0mm double-sided assembly is used, the weight will only increase by 1.89kg compared to the single-sided assembly, and the proportional weight will only increase by 8.9%. The mature industrial application of 2.0mm thickness photovoltaic glass will make the double-sided double-glass components usefully control, and solve the industrial problems of double-glass components that are difficult to install. The industry debate about whether to choose “photovoltaic glass” or “tongming backboard” will determine the world due to the maturity of photovoltaic glass ≤2.0mm.
When I talk about it, I believe the teacher will pay attention to the progress of the industrialization of 2.0mm-thick photovoltaic glass. Recently, the evidence I have obtained in Fuli Special Research is like this: 2.0mm photovoltaic glass is now in mass production (using imported steel equipment), and there is no problem in the production of 2.0mm-thick glass original sheets. The difficulty lies in the steel equipment. Today, only Pinay escortThe imported equipment must meet the steel demand of 2.0mm glass, and the price of imported equipment is more than 5 times the price of domestic equipment of the same capacity, and the production capacity is still lost. This is the key to the cost-effectiveness. Today, Fulite is focusing on 2.0mm glass, and it is expected that mature and low-cost solutions will be planned at the end of this year. Sugar babyI was also happy to learn from this research that Longi uses Amaton’s steel glass to produce 2.0mm+2.0mm double-sided double-glass components in batches.
2. The combination of the components and glass will jointly increase the thickness of the components factory by 40% even if Escort is the current single-faced component, and the proportion of photovoltaic glass parts to the total component is also higher than 15.2kg÷21.01kg=72.Sugar baby3%, and if we fully welcome the 2.0mm-thick double-sided era in the future, the proportion of glass will reach 19kg (glass parts) ÷ 22.9 (total parts) = 82.96%. The profits of the assembly factory are thin, and the cost of glass transportation is huge, which forces us to think about how to use the assembly factory and glass factory area layout Escort The cooperation at the manila office is to save glass transportation and the local capital of this department. Especially in the era of unorganized components and the tide of full popularity of double-sided double-glass components, this kind of thinking is even more necessary. 1. The cost of packaging materials and transportation accounts for 10 to 15% of the total cost of photovoltaic glass. The cost of glass transportation is huge, and the profit of the component factory In a time when silicon data has high value and high price of components, the cost of glass accounts for a very low proportion, so how much is the cost of glass. However, after the country, the price of photovoltaic components has dropped from 27 yuan/watt in 2008 to 1.7 yuan/watt now, while the price of glass remains relatively stable, which makes the cost of photovoltaic components In the money structure, the proportion of glass is getting higher and higher, especially in the era when components are unmotivated, glass will account for a higher proportion of glass instead of back panels, and the cost of glass in the components will be from 1% at the lowest time to 14% of double glass components. In the expected future, silicon data cost and battery sheet cost will still decline, while photovoltaic glass cost and price will remain stable. So, In 3 to 5 years, this knowledge competition will combine questions and discussions. In terms of dimensions of participants-Graduate, the era of unorganized components has arrived comprehensively, and the cost of photovoltaic glass accounts for more than 15% or perhaps a widespread phenomenon.
Among the cost structure of photovoltaic glass, about 10 to 15% of the cost is the cost of transportation and packaging materials. A piece of glass is transported from a glass factory to a componentThe factory’s cost is not low. The pallets, packaging films, and dryers required for glass transportation require a large amount of 200 yuan per ton. The maximum glass that a pallet can transport is 200㎡. This door’s cost of 1㎡ of glass is required for 1㎡. Not only this, in order to ensure that the glass will not be scratched due to friction during the long distance transportation process, it is necessary to set up spacer paper, which will also cost a few gross per square meter. Finally, the transportation cost is the money. After researching, it was found that the transportation distance from photovoltaic glass from the glass factory to the component factory is often between 200 and 500 kilometers, mainly steam transportation, which is equivalent to the fuel cost per square meter of steam Sugar daddy cost ≥1 yuan.
2. The 1GW machineless assembly factory has a joint venture of 20 million yuan per year to undertake the previous section. If we want to set up the assembly factory next to the glass factory, and reduce the cost of packaging materials through easy packaging and reusing packaging methods, then the old calculation is: a 2 yuan savings per square meter of glass and the cost of packaging materials.
1GW component factory can produce 3.4 million pieces of 60-type units per yearSugar baby parts (front area 1.65㎡). If the double-sided glass packaging method is adopted, the glass area of each piece is 1.65×2=3.3㎡, which means that the annual demand cost of 1GW components factory loses 3.4 million × 3.3=11.22 million square meters of glass. If the area is saved 2 yuan per square meter of glass due to the TC:
