Description

technical field [0001] The invention relates to the technical field of photovoltaic curtain walls, in particular to a photovoltaic curtain wall-based greening system and an implementation method. Background technique [0002] Photovoltaic curtain wall system is the focus and difficulty of BIPV research. The system is a climate-responsive building envelope. At the same time, the space provided by the building facade can be used to install solar photovoltaic panels to convert solar energy into electrical energy to relieve the pressure on the power grid. It can be said to kill two birds with one stone. [0003] During the use of the traditional photovoltaic curtain wall, a layer of dust will accumulate on the surface of the photovoltaic curtain wall with the passage of time. Due to the high labor cost of high-altitude cleaning, and the photovoltaic curtain wall is easy to be damaged compared with the glass curtain wall, the photovoltaic curtain wall will be damaged every time. ...

Problems solved by technology

[0005] The purpose of the present invention is to provide a photovoltaic curtain wall-based greening system and implementation method to solve the above-mentioned background technology. In the process of using the traditional photovoltaic curtain wall, a layer will be accumulated on the surface of the photovoltaic curtain wall as the use time goes by. Dust, due to the high labor cost of high-altitude cleaning, and the photovoltaic curtain wall is easy to be damaged compared to the glass curtain wall, so that there is an interval between each photovoltaic curtain wall cleaning and even natural cleaning by rainwater in rainy days. There is thick or thin dust attached, and this layer of dust will prevent sunlight from shining through the surface glass of the photovoltaic curtain wall to the photoelectric conversion components in the photovoltaic curtain wall, which will reduce the light intensity received by the photoelectric conversion components and further reduce energy utilization. Secondly, compared with glass, the dust on the surface of the photovoltaic curtain wall has a high surface roughness, low light reflectivity, and a deep color with a high light absorption rate. Further, the surface dust has a high light absorption rate and a high light-to-heat conversion rate, which increases the temperature of the photovoltaic curtain wall. Furthermore, since the higher the temperature of the photoelectric conversion component, the lower the photoelectric conversion rate, the existence of the gray layer, by increasing the temperature of the photovoltaic curtain wall, further reduces the photoelectric conversion rate of the photovoltaic curtain wall, and at the same time increases the emission of the photovoltaic curtain wall. heat problem
