1.2 market prospect and current progress of the project
1.2.1 market prospect of the project
With the rapid development of science and technology, the use of glass products has become more and more extensive, the new products created by glass products as basic components are constantly emerging.After we experienced the era of large glass curtain wall, due to the increasing importance of environmental protection, energy conservation and safe production, insulating glass, low-e insulating glass and toughened glass are gradually replacing the traditional glass sheet and entering people’s life.Facing the increasingly fierce competition in the domestic glass market, in the future, the continuous development and introduction of high-end products, product differentiation will become the main means for glass enterprises to gain advantages.Now, a new kind of energy-saving product is emerging, it is the solar photovoltaic cell.One of the key components of solar photovoltaic cells is the packaging glass.This new product has begun to attract the attention of more and more glass enterprises, becoming one of the new high-tech products that many enterprises plan to develop.
At present, the main technology of producing solar cell glass is calendering.He is made of a special embossing roller that presses a special pattern on the surface of ultra-white glass.It is an indispensable component of solar photovoltaic cells.According to concerned respect predicts, the glass product that grows bigger in the next five years is solar cell USES ultra white embossed glass, namely solar cell encloses glass.At present, there are only a handful of large glass enterprises in China to produce ultra-white embossed glass for solar panels, so the market prospects are quite broad.
The rise in international oil prices has brought huge inflationary pressure to the world.It is urgent to develop the new energy industry.As the substrate material of solar thermal and photoelectric conversion systems, the industrialization of photovoltaic glass fundamentally promotes the continuous expansion of the production scale of the photovoltaic industry.On January 1, 2006, China formally implemented the renewable energy law, which provides a strong legal guarantee for the utilization of solar energy and the development of the solar energy industry in China.
According to statistics, the actual output of solar photovoltaic glass market in China only accounts for 65-70% of the total demand at present, with a large gap in the domestic market, and with the rapid growth of the photovoltaic industry, the gap of photovoltaic glass will further expand.Every 1 mw solar cell installation requires 15,000 square meters of photovoltaic glass, and every year nearly 4,000 mw solar cell installation worldwide requires about 60 million square meters of photovoltaic glass, with an annual growth rate of 40%.
With the increasing integration of photovoltaic power generation technology and architecture, the photovoltaic curtain wall with great development potential, in addition to achieving the same aesthetic effect as the glass curtain wall, can also use solar photovoltaic power generation technology to generate new energy, is now becoming a new favorite in the international architecture industry.In Shanghai have a zero energy comprehensive utilization of solar energy demonstration building, the three-story building nearly 1/5 of the walls and roof covered more than 300 solar panels, building glass curtain wall are made into “biscuit” — in the double deck glass Mosaic pieces of solar panels, the balcony also specially designed a circle by solar panels into fence.According to introducing, this is not expensive, the cost of solar building with solar panels of 50 yuan per watt price calculation, the entire building is about 2 million yuan expenditure for solar power, make up about a quarter of the overall cost, compared with 10000 yuan/square meters of high-grade glass curtain wall, solar glass curtain wall cost only 4000 yuan/square meters.At the 2007 Shanghai solar energy international exhibition, a prototype room with solar photovoltaic curtain wall was displayed. The double-glazed panels with solar panels were made into shutters, which attracted wide attention in the exhibition.This shows that many safety problems and light pollution problems of traditional glass curtain wall can be solved well by using solar photovoltaic panels.In the long run, this technology is very scalable, promising.It will break through the existing use of solar photovoltaic cells, so that solar photovoltaic cells are applied to a wider range of building fields.
The main reason for the low average conversion rate of solar cells in China is the low degree of domestic production of special materials, such as packaging glass is completely dependent on imports, the low iron content of high light transmittance substrate glass market still cannot meet the demand, scientific research results have not been quickly converted into industrial advantages.Therefore, the domestic market for solar photovoltaic cell packaging glass needs domestic glass enterprises to increase efforts to break the monopoly of foreign enterprises.
The ultra-white embossed glass, which is dedicated to solar photovoltaic cells, is quite profitable compared with ordinary glass.At market prices last year, the finished product was imported for about $15 a square meter, or about 120 yuan a square meter.Raw imports cost $8 to $9 per square meter, or more, about 64 to 72 yuan per square meter.This is at present the domestic other ordinary glass price is incomparable.
Now, our country is advocating the establishment of energy-saving society, solar energy as a renewable resource, is getting more and more widely used.The market prospect of related solar photovoltaic cells is very promising, and its promotion in the domestic market will be faster and faster.As a result, demand for ultra-white embossed glass, the main component of solar photovoltaic cells, will grow rapidly.Considering that at present this kind of glass mainly depends on imports to solve the domestic glass enterprises have a great opportunity for development.And this kind of product really is a kind of product that can expect to have richer profit.And the market profit of the average glass product today is simply not at the same time.We have reason to believe that the ultra – white embossed glass in the future not long time, will become the glass industry profit pillar products.
