Baoding photoelectric use of a "breathing solar glass curtain wall" power

Learned from the High Technology Development Zone in Baoding, Hebei Province, are speeding up the construction of China's first here, "Optical buildings" is nearing completion. Industry experts believe that this the first time, solar photovoltaic systems and building integrated demonstration project for solar energy industry for China's future development and practical application to provide an important basis and examples.

According to reports, this "photoelectric buildings" in the only state-level renewable energy and energy equipment industry base - High-tech Development Zone, Baoding, Hebei Province, twenty-six stories high main building, its principal and subsidiary buildings can accept sunlight the outer walls, roof, platform and other parts of the nearly 30,000 square meters, have been installed with "breathing solar glass curtain wall." The wall can light into electricity, these energy not only meet the building's public lighting, but also can be incorporated into local power grids, electricity generation equivalent of a small hydropower station. Meanwhile, the entire project landscape lights, garden lights, lawn will use solar energy and energy-saving LED lighting technology combined.

According to direct the construction of technical personnel, this "photoelectric building" looks exactly like a "circuit board", adopted many domestic and international new technology never before. And because "breathing solar glass curtain wall" is double tempered glass used in photovoltaic cells sandwiched between the structure, addition to power generation, but also has the sun, environmental protection, energy conservation, noise, aesthetics, light transmission is good, firm structure, and many other advantages, life of up to twenty-five years.

It is understood, Hebei Baoding building is full "of Baoding? China Power Valley" and the "Solar City", the region gathered in Tianwei Yingli, Sailing and many other new energy backbone enterprises. "Optical buildings" completed, will attract domestic and foreign famous "electric font" industry, technology, personnel, information gathered in making the city truly be a world influence the characteristics of type, international new energy and energy equipment manufacturing base.

The development of solar glass curtain wall

In 2002, the Science Park Square Building, a large group completed the first one photovoltaic glass curtain wall in China, prices of nearly 10,000 yuan per square meter; Garden Expo column total installed capacity of solar photovoltaic power station in Asia, with a total investment of about 7.5 million U.S. dollars ... ... amazing solar building investment is evident.

  

The past, not in large scale solar building, mainly crystalline silicon solar panel prices remain high, the lowest price per square meter, have more than 8000 yuan; other traditional solar panel manufacturing complex process, in particular, will be processed into high purity silicon The key technology of solar grade polysilicon, master of several large companies in foreign hands, causing almost all of our solar modules rely on imports situation.

Amorphous silicon glass curtain wall is sprayed gas in the glass, to produce amorphous silicon thin film solar, the same conversion rate, raw material use crystalline silicon solar panels only 1%, a decrease of the key raw material of silicon refined into polysilicon grain areas of this technology, so the cost greatly reduced. Previously, amorphous silicon thin film battery is used in watches, mobile phones, instruments, computers, toys and other small pieces of products. Last year, the highest benefits will this technology and products for the glass curtain wall, and was listed as the Ministry of Construction in 2004, industrialization projects.

National Stadium to install solar glass curtain wall

National Indoor Stadium project installed a 24 imported from Germany the most advanced solar glass curtain wall, which marks National Stadium, 100 kW grid-connected PV projects entered the installation phase. Reporter yesterday from Beijing Urban Construction Group was informed that the Ministry of Construction Contract, the National Stadium will install 1124 solar cells, and this is the first Olympic project to install solar projects. After the completion of the design daily output of 100 kW rated, added to the low voltage distribution grid system for the 20,000 m2 ground lighting.

National Indoor Stadium 100kW grid PV power generation projects is the national "15" science and technology research projects. The project's total installed capacity of PV power plant is 102.5 MW installed in the training hall roof, the competition hall roof and solar glass curtain wall in the south, about 1,000 square meters of solar panels, solar cell matrix to the absorption of solar radiation unified by a special line solar power delivered to the basement control room, through the power conversion equipment, processing, and then by special equipment and network transmission to low voltage distribution system.

Solar glass curtain wall of glass used

As the solar panels are almost all glass curtain wall, so the performance is good or bad glass, solar glass curtain wall system on the whole energy-saving effect is very large. Selection of main considerations glass interior lighting, comfort, performance glass such as wind pressure intensity index. Energy index of glass systems, the main consideration of glass insulation, heat insulation. The concrete is put into the glass of the heat transfer coefficient and shading coefficient.

Solar glass curtain wall using "create" energy

Use of modern science and technology, solar glass curtain wall to "create" energy has been achieved. Use of glass and light level, with modern optical technology and products, convert light into electrical energy, building energy efficiency would create a brighter future. Germany recently proposed Energy2 Asahi Grumman concept, they believe, through modern scientific and technological means in reducing energy consumption and increase the utilization Neng Liang, it is also capable of producing the power savings is no longer a sum of the relationship between the overall effect is greater than the sum of the effect of this is the system on a concrete manifestation of the overall concept.
