On the 24th, Sun Yan, a professor of Tongji University and academician of the CAE Member, said that solar photovoltaic glass could be used to replace
Home Decor glassware in high-rise buildings at the conference on "energy conservation, emission reduction and environmental issues in urban underground space".
High rise buildings collecting solar energy
Solar energy contains unlimited energy. Today, the emergence of solar photovoltaic glass will provide various possibilities for urban energy conservation.
There are currently 3000-4000 high-rise buildings in Shanghai. Many people always think of writing articles on the exterior walls of buildings. Solar photovoltaic glass is one of the types being tested at present. At present, the project has been submitted to the government for decision.
"From the outside, ordinary people can't see the difference between photovoltaic glass and ordinary mouthblown glassware." Sun Hao said that this can ensure that people's eyesight will not be affected. Some people predict that the use of photovoltaic
wine glasses will increase the value of the world's highest building.
Metro can be combined with photovoltaic
Of course, it can reach the sky directly or go deep underground. The "combination" of subway and photovoltaic has been achieved in some cities. The grass on the top of the German subway is covered with solar photovoltaic panels, providing energy for subway operation; If we move the system to Shanghai, similar outlets will be installed at the subway outlets in Kaohsiung, Taiwan. This will save a lot of subway operation costs.
But there are also practical difficulties. Sun Hao said that if the existing subway in Shanghai is to be replaced with photovoltaic "clothes", this is a problem of investment. Costs should not be underestimated. He said that cities with new subways can first design photovoltaic.
The photovoltaic industry benefits from the development of energy storage technology
Reliance on lighting is a "weakness" of the solar photovoltaic industry. With the development of energy storage technology, in addition to the complete absence of photovoltaic at night, it can also ensure the safety of subway operation in rainy days.
China has always been in 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 subway can bring new development opportunities for China's photovoltaic industry and change the pattern that China relies heavily on coal for power generation.
