Solar energy contains infinite energy. Today, the emergence of solar photovoltaic glass will provide countless possibilities for energy saving in cities. At the Academician Salon of "Energy Conservation, Emission Reduction and Environmental Protection of Urban Underground Space" held yesterday, Sun Jun, a professor of Tongji University and an academician of the Chinese Academy of Engineering, said that it is promising to replace the glass of high-rise buildings with solar photovoltaic glass.

Tall buildings collecting solar energy

There are currently 3000-4000 high-rise buildings in Shanghai. Many people invariably thought of making articles on the outer wall of the building, and solar photovoltaic glass is one of the types that are currently being tested. At present, the project has been submitted to the government for decision.

"From the appearance, ordinary people can not see the difference between photovoltaic glass and ordinary glass." Sun Jun said, this can ensure that it will not affect people's vision. Some people predict that the use of photovoltaic glass will greatly increase the value of the world's tallest building.

Metro can be combined with photovoltaic

Can reach into the sky, of course, can also go underground, the "combination" of subway and photovoltaic, indeed in some cities. The grass on the top of a subway in Germany was covered with solar photovoltaic panels to supply energy for the operation of the subway. A similar device was installed at the subway exit of Kaohsiung, Taiwan. If we move this system to Shanghai , Will save a lot of subway operating costs.

But there are also practical difficulties. Sun Jun said that if you want to replace the existing subway in Shanghai with photovoltaic "coats", it is a cruel thing that needs to be underestimated, and the cost cannot be underestimated. He said that cities with new subways can give priority to photovoltaics in their design.

Photovoltaic industry benefits from the development of energy storage technology

Relying on light is a "weak spot" in the solar photovoltaic industry. With the development of energy storage technology, in addition to completely no use of photovoltaics at night, rainy days can also guarantee the worry-free operation of subways.

China has always been at the forefront of the world in the solar photovoltaic industry, but it is rarely used in China. One of the reasons why the photovoltaic industry is cold is that there are no suitable projects. Bring new development opportunities for China's photovoltaic industry, change the pattern of China's power generation relying heavily on coal.
