Technical Field

The embodiment of the invention relates to the field of photovoltaic application, in particular to a photovoltaic curtain wall system.

Background

Solar power generation systems are commonly used in modern life. In modern buildings, most of solar photovoltaic cells are placed on a roof or a building vertical surface, a photovoltaic curtain wall system is attached to the building, the building serves as a carrier to play a supporting role, and the photovoltaic curtain wall system mainly completes a power generation task. The photovoltaic curtain wall system on the outer vertical surface of the curtain wall of the building utilizes the space provided by the vertical surface of the building to install the solar photovoltaic panel and converts solar energy into electric energy so as to relieve the pressure of a power grid, thereby achieving two aims at one stroke.

Solar altitude: for a certain place on the earth, the solar altitude refers to the included angle between the incident direction of sunlight and the ground plane, and in the professional sense, the solar altitude refers to the included angle between the sunlight of the certain place and the ground tangent plane connected with the center of the earth through the place. When the solar altitude is 90 degrees, the solar radiation intensity is maximum; when the sun is obliquely directed to the ground, the intensity of the solar radiation is small.

However, in the solar photovoltaic power generation system on the outer vertical surface of the building curtain wall in the prior art, the photovoltaic curtain wall and the glass curtain wall are generally combined to be arranged on the surface of the outer vertical surface of the curtain wall between floors, and as the irradiation angle of the sun changes throughout the year and even in the middle of a day, especially the radiation intensity of the sunlight is the largest when the incident angle of the sunlight is closer to the vertical direction, the solar energy is also the largest at the moment, but the photovoltaic curtain wall is fixedly arranged, so that the solar energy cannot be collected and utilized to the maximum.
