Description

Technical Field

[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductor interfaces to directly convert light energy into electrical energy. It is mainly composed of three parts: solar panels (modules), controllers and inverters. The main components are made of electronic components. Solar cells are packaged and protected after being connected in series to form large-area solar cell modules, which are then combined with power controllers and other components to form photovoltaic power generation devices.

[0003] For example, "CN116232187A" is a photovoltaic panel fixing device, including a base plate, a lifting plate is arranged on the base plate, the corners of the lifting plate are connected to the base plate by movable telescopic columns, a rotating plate is arranged on the upper side of the lifting plate, one side of the rotating plate is hinged to the lifting plate, a clamping assembly is arranged on the upper side of the rotating plate, and two opposite sides of the rotating plate are hinged with a support rod, and the ends of the two support rods facing away from the rotating plate are respectively connected to a moving part, and the two moving parts are respectively slidably connected to a pair of sides of the rotating plate, and then a jacking assembly is arranged between the lifting plate and the base plate, and the lifting part of the jacking assembly is connected to the lifting plate, and a pushing assembly is also installed on the upper side wall of the base plate, and the two output ends of the pushing assembly are respectively connected to a moving part. This device improves the ability of the photovoltaic panel to cope with strong winds and avoids damage from strong winds by folding the photovoltaic panel and placing it close to the ground.

[0004] However, in the prior art, for photovoltaic panels installed in groups, horizontal and vertical keel brackets are usually installed in an open area, a plurality of square frames are formed between the horizontal and vertical brackets, and the photovoltaic panels are installed on the horizontal and vertical keels so that each photovoltaic panel is neatly arranged. The installed photovoltaic panels are usually tilted at a fixed angle and direction and cannot be adjusted at any time. From sunrise to sunset every day, the angle of the sun shining on the photovoltaic panels will change. Since the angle of the photovoltaic panels is always fixed, the photovoltaic panels cannot maximize the sunlight energy received by the photovoltaic panels according to the height and direction of the sun. Moreover, if each photovoltaic panel is driven individually to adjust its angle, more power sources are required, and the cost of use is high. Summary of the invention
