Analysis of the market status and development trend of China's BIPV industry in 2022
Building Integrated Photovoltaics (BIPV) refers to the installation of photovoltaic modules on the surface of the building envelope to provide electricity, and at the same time as a functional part of the building structure to replace some traditional building structures such as roof panels, tiles, windows, building vertical It can also be made into photovoltaic multi-functional building components to achieve more functions, such as photovoltaic photothermal system, combination with lighting, and combination with building shading.
According to the type of installation, the construction of photovoltaic building integration is divided into three types, namely building material type installation type, component type installation type and installation type combined with roof and wall.
The superiority of BIPV is obvious
In addition to the power generation function, the photovoltaic building system also has the necessary performance and unique decorative functions for the outer protection of the building, such as wind pressure resistance, water tightness, air tightness, sound insulation, thermal insulation and shading. The perfect combination of various functions of maintenance, building energy saving, solar energy utilization and building decoration. Its advantages are mainly as follows:
Photovoltaic curtain wall is the main form of BIPV
Photovoltaic curtain wall is an important form of photovoltaic building integration. From the current point of view, there are two ways to combine photovoltaics and buildings: one is the combination of buildings and photovoltaic systems, and the other is the combination of buildings and photovoltaic devices. There are mainly the following eight:
The total output value of building curtain wall has increased year by year
my country's building curtain wall industry started in 1978. After years of development, especially the rapid development in the 21st century 90s, it has become the world's largest curtain wall producer and user by the beginning of the 21st century. At present, the annual production capacity of curtain wall in my country is far more than 100 million square meters, and the total value of curtain wall projects is increasing year by year. According to the statistics of China Building Decoration Association, the total output value of building curtain wall projects has increased from 300 billion yuan in 2014 to 490 billion yuan in 2020. In 2020, the output value of building curtain wall projects in my country will increase by 8.9%. In 2021, the total output value of building curtain wall projects in my country will be about 531.7 billion yuan.
It is estimated that the future market space of photovoltaic curtain wall is expected to exceed 150 billion yuan, and the current market space is less than 10 billion yuan.
Efficiency, beauty and industrialization are the development directions of photovoltaic curtain walls
