Photovoltaic glass can replace high-rise building glass and become the new favorite

On the 24th held at the “Saving Energy Saving, Emission Reduction and Environmental Issues in Urban Underground Space” academician Sharon, a professor at Tongji University and a member of the Chinese Academy of Engineering Sun Yan, said that it is possible to use solar photovoltaic glass instead of high-rise building glass.

High-rise building collecting solar energy

Solar energy contains infinite energy. Today, the appearance of solar photovoltaic glass will provide numerous possibilities for energy conservation in cities.

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

“From the outside, ordinary people do not see the difference between photovoltaic glass and ordinary glass.” Sun Hao said that this can ensure that it will not affect people's vision. Some people predict that the use of photovoltaic glass will increase the value of the world's tallest building.

Subway can be combined with photovoltaic

Can reach into the sky, of course, can also go deep underground, subway and photovoltaic "combination", in some cities did. The grasslands on top of a subway in Germany were covered with solar photovoltaic panels to provide energy for the operation of the subway; similar exports were installed at the subway exit in Kaohsiung, Taiwan, if we moved the system to Shanghai. It will save a lot of subway running costs.

But there are also practical difficulties. Sun Hao said that if Shanghai's existing subways are to be replaced with PV's "clothes," it is a matter of devotion. The cost should not be underestimated. He said that cities with new subways can design photovoltaics first.

Photovoltaic industry benefits from energy storage technology development

Relying on lighting is a “weak spot” in the solar photovoltaic industry. With the development of energy storage technology, in addition to the complete absence of photovoltaics at night, the rainy days can also guarantee the safety of subway operations.

China has always been at the forefront of the world in the solar photovoltaic industry. However, it is rarely used in the real world. One of the reasons for the cold weather in the photovoltaic industry is that there are no suitable projects. Sun Hao believes that both high-rise glass and photovoltaic metros can Bring new development opportunities for China's photovoltaic industry, change the pattern of China's power generation relying heavily on coal.
