Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, specifically to a photovoltaic curtain wall system with a horizontal exposed frame. Background Technology

[0002] Photovoltaic power generation, as an important technology in the field of renewable energy, has received widespread attention and application in recent years. Among them, photovoltaic curtain walls, as a model of integrating photovoltaic power generation technology with buildings, can not only effectively utilize solar energy to generate electricity, but also serve as the building's external envelope, combining aesthetics and practicality.

[0003] Existing technologies have conducted some research on photovoltaic curtain wall systems. See patent document application number 201911161312.X, which discloses a frameless photovoltaic glass curtain wall. This system mainly consists of aluminum alloy vertical frames, aluminum alloy horizontal frames, transparent glass panels, and photovoltaic glass panels. The bottom of the aluminum alloy vertical frames is connected to the aluminum alloy horizontal frames by welding. Both have a frame formed on one side, and the transparent glass panel is fixed to one side of the frame by adhesive bonding. During installation, the aluminum alloy vertical and horizontal frames at each node are pre-installed first. Then, the main keel is fixed inside the aluminum alloy vertical frames, and the secondary keel is fixed on top of the main keel. Next, the transparent glass panel and photovoltaic glass panel are placed into the frame composed of the main keel, secondary keel, and frame, thus realizing the installation of the transparent glass panel and photovoltaic glass panel. Finally, the aluminum alloy vertical and horizontal frames are assembled with the various nodes to complete the assembly of the entire photovoltaic curtain wall.

[0004] Therefore, by embedding transparent glass panels and photovoltaic glass panels into the concealed frame structure composed of the main keel, secondary keel, and frame, a fully concealed frame installation of photovoltaic glass is achieved, improving the overall aesthetics of the photovoltaic curtain wall. However, due to the low strength of photovoltaic glass, the fully concealed frame installation method carries the risk of photovoltaic glass detaching during long-term use.
