Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, specifically a wind-resistant photovoltaic power generation panel. Background Technology

[0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy using the photovoltaic effect at the semiconductor interface. Photovoltaic power generation mainly consists of three parts: solar panels (modules), controllers, and inverters. The main components are made up of electronic components. Solar cells are connected in series and then encapsulated for protection to form large-area solar cell modules. Combined with components such as power controllers, this forms a photovoltaic power generation device.

[0003] Existing photovoltaic panels are all designed as a single unit, and their surfaces do not have ventilation functions. They have a large structural wind resistance and are prone to bending or overturning in strong winds, resulting in poor stability and wind resistance. Utility Model Content

[0004] The purpose of this utility model is to provide a wind-resistant photovoltaic power generation panel to solve the problems of existing photovoltaic power generation panels, which are all designed as a single panel, have no ventilation function on their surface, have large structural wind resistance, are easy to bend or overturn in strong winds, and have poor stability and wind resistance.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A wind-resistant photovoltaic panel includes a back plate, on which solar cells are fixedly connected at equal intervals on the top. Wind vents are provided at the top of the back plate, in the middle of four adjacent solar cells. A transparent cover plate is fixedly connected to the top of each solar cell. A frame is snapped around the transparent cover plate, and the frame is bolted to the back plate on all four sides. Buckles are provided on the surface of the transparent cover plate at positions corresponding to the wind vents. Rubber sheets are integrated and fixed on all four sides of the inner wall of each buckle. Reinforcing ribs are integrated at equal intervals on the bottom surface of the back plate.

[0007] Preferably, a junction box is fixedly connected to one side of the bottom of the back plate.

[0008] Preferably, the outer side of the solar cell is encapsulated with EVA film.

[0009] Preferably, the frame is made of aluminum alloy.

[0010] Preferably, the buckle consists of a frame and a limiting frame, and the frame and the limiting frame are connected by a buckle.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, by opening wind holes at corresponding positions on the back panel and the transparent cover, a porous design can be achieved on the surface of the photovoltaic panel to increase wind permeability, thereby reducing wind resistance of the photovoltaic panel in windy weather and reducing the risk of the entire photovoltaic panel tipping over. Furthermore, the bottom of the back panel is integrated with reinforcing ribs to ensure the structural strength of the entire panel, reduce the risk of bending in windy weather, and ensure its stability and wind resistance.

The inner wall of the snap-fit ​​7 is integrated with rubber sheets 8 on all four sides to block the wind hole in light wind weather to ensure the integrity of the photovoltaic panel. In strong wind weather, the rubber sheets are turned outward to open the wind hole and ensure the ventilation of the photovoltaic panel. The bottom surface of the back plate 1 is integrated with reinforcing ribs 9 at equal intervals to ensure the structural strength of the whole plate, reduce the risk of bending in strong wind weather and further ensure its stability in use.
