It usually consists of two layers of glass, solar cell wafers arranged between the glasses, and special metal wires. The solar cell wafers are sealed between the two glasses through lamination technology. This kind of glass not only has the photovoltaic effect and can generate electricity, but also has excellent heat-insulating performance due to its unique structure and material selection. Usually, a frame is arranged on the outer side of the heat-insulating photovoltaic glass for protection and subsequent installation, etc.

[0003] In a kind of anti-fouling and heat-insulating photovoltaic glass disclosed in the existing patent publication number CN219643875U, it includes an installation frame and a photovoltaic glass assembly installed inside the installation frame. The installation frame includes a bottom frame and a packaging frame. The inner side walls of the bottom frame and the packaging frame are both movably connected to the surface of the photovoltaic glass assembly. The bottom frame is fixedly connected to the packaging frame to form an air duct for ventilation; an air suction assembly for air suction and exhaust is arranged on the surface of the packaging frame. The air suction assembly is located inside the installation frame, and two air vents for ventilation are also opened on the packaging frame.

[0004] The above-mentioned glass is a photovoltaic glass, but the configured installation frame has a relatively complex structure, which affects subsequent installation and the light transmission use of the photovoltaic glass, and needs to be improved. In view of the above problems, a heat-insulating photovoltaic glass is proposed. Content of the Utility Model
