The size of the building curtain wall has risen years. The curtain wall is the outer wall of the building, and it is a lightweight wall commonly used in modern large and high -rise buildings. Composed of a panel and a support structure system, a building outer surrounding structure or decorative structure that can have a certain displacement ability or its own deformation ability, and does not assume the main structure of the main structure. According to the component, it can be divided into frame -type curtain walls, unit curtain walls, and point -type curtain walls. The framework curtain wall includes bright frames and hidden frames. In recent years, the output value of my country's curtain wall project has increased year by year. The output value of the construction curtain wall project has increased from 150 billion yuan in 2010 to 490 billion yuan in 2020. In the past ten years, the GAGR is 12.57%, of which the year -on -year increases from 2016 to 2020 were 6.25%/11.76%///11.76%// 6.58%/11.11%/8.89%
According to the China curtain wall authority, in 2021, the building curtain wall project in China mainly uses glass curtain walls, accounting for 41%, accounting for a decline, but it still exceeds other types. Gradually rising to 19%; the application of metal curtain walls, especially aluminum board curtain walls, is increasing. As a renewable and more environmentally friendly curtain wall type, the current plasticity of aluminum plates is more plastic in pursuing personalized design and cupping. The market will be wider. Judging from the distribution of the curtain wall engineering area, the proportion of engineering in East China and South China reached 46%, accounting for nearly half of the construction curtain wall project in China.
The photovoltaic curtain wall photovoltaic system includes the photovoltaic panel (that is, solar cells), the controller, the battery pack, the inverter, etc. of the photovoltaic curtain panel. Its working process is: Under the sun, the photoelectric curtain wall generates DC power by the optoelectronics board, which is stored through a multi -polar set, that is, the DC electricity generated by the optoelectronic curtain wall under the control of the solar controller is stored through the battery pack. The DC is transformed into an AC power that can be used in the process of inverting and transformer, and delivered to the power supply network or directly drive the load.
