According to the “Circular on Organizing and Implementing the 2012 Solar Photovoltaic Building Application Demonstration†issued by the Ministry of Finance at the end of last year, the photoelectric integration project closely linked with the height of building materials, such as building materials, is tentatively set at RMB 9/watt for 2012. Increased by 3 yuan in 2011.
With the increase of PV building subsidies, the enthusiasm for the development of photovoltaic buildings will be enhanced and the development of photovoltaic building integration market will be promoted. It is understood that China currently has 48 billion square meters of building area. If 10% of them establish a BIPV system, a 500GW solar battery market will be formed.
The development of the photovoltaic building integration market has opened up a new market for the photovoltaic industry in China. In this area, thin-film solar cells occupy significant advantages over crystalline silicon solar cells.
Thin-film solar cells are a new generation of solar cells. Compared with conventional crystalline silicon cells, thin-film solar cells have significant advantages such as raw material saving, low energy consumption, low cost, and convenience for large-area continuous production. Amorphous silicon thin-film solar cells are also rich in raw materials, non-toxic, non-polluting, and have the lowest energy consumption.
In terms of solar roofs, one of the main applications for photovoltaic buildings, thin-film batteries can exert their technical advantages. First of all, the thin-film battery has a weaker light response effect and a relatively low unit cost. Second, the thin film photovoltaic module is easier to integrate with the building to achieve structural integration. While saving the cost of building components and other materials, it can also generate economic benefits through power generation. Improve the beauty of the building.
Another major application of photovoltaic buildings is the same with glass curtain walls. In this field, the characteristics of thin-film solar cells, light weight, good light transmission, good flexibility, and easy integration with building materials, can be fully utilized. The traditional crystalline silicon glass curtain wall is composed of crystalline silicon square plates. The views that people see from the inside are all one by one, not complete, which makes the crystal silicon glass curtain walls have a lot of defects. Therefore, analysts believe that the market development of photovoltaic building integrated market, the ultimate benefit will be the thin film solar energy industry, with the development of photovoltaic building integration market, the thin-film solar energy industry will usher in a rapid development period.
Analysts pointed out that with the stimulation of favorable policies, the development of photovoltaic building integration market dominated by thin-film solar energy and the continuous expansion of industry leaders will lead the future of thin-film solar energy.
The industry will usher in a new round of development cycle and it is expected to change the current market structure.
Other Constructions SS Wire Rope
Wire rope quality judgment:
1. Specific gravity. The diameter of the wire rope is the same, the heavier the specific gravity, the better the quality of the wire rope.
2. Steel wire rope core. The stronger the core of the wire rope, the heavier the specific gravity, the better the support for the outer strand of the wire rope, and the better the quality of the wire rope.
3. Materials. The material is the steel grade and strength. The higher the steel grade, the better the quality of the wire rope with higher strength.
4. After the rope is cut, the slightly loose quality is good, and the quality of the wire rope with a relatively long lay length is better than that with a short lay length.
5. The anti-corrosion ability of 316 Stainless Steel Wire Rope is stronger than that of 306 stainless steel wire rope, and the anti-corrosion ability of 306 is stronger than that of hot-dip galvanized steel wire rope. The quality of hot-dip galvanized steel wire rope is better than that of electro-galvanized steel wire rope; the quality of nylon plastic-Coated Steel Wire Rope is stronger than that of PE plastic-coated steel wire rope.
