[0002] A photovoltaic power station refers to a photovoltaic power generation system that utilizes solar energy and adopts special materials such as crystalline silicon panels, inverters and other electronic components. It is connected to the power grid and transmits electricity to the power grid.

[0003] Photovoltaic power generation is becoming increasingly common in today's renewable energy power generation field. During operation, photovoltaic modules are affected by the environment, natural factors such as hail and lightning strikes, or internal factors such as hot spots and hidden cracks, which can easily cause irreversible damage. At this time, the damaged modules need to be removed from the frame and replaced with new ones.

[0004] Photovoltaic modules are mostly installed at high places. Workers need to remove them when replacing and repairing them. Due to their high length and width specifications and the relatively fragile surface crystalline silicon, as well as the inconvenience of working at heights, it takes multiple workers to cooperate in removing them. In addition, the removed photovoltaic modules or the new photovoltaic modules to be replaced are not convenient to carry and place, making replacement and repair difficult. In addition, due to the tilt angle of the module frame, the scaffolding can only be built on the back of the module, making module replacement extremely time-consuming, labor-intensive and difficult to complete.
