[0047] Working principle:

[0048] When installing the solar panel, place the connection block 22 in the placement groove 26, and place the connection wire 25 in the card groove 24. At this time, one end of the connection wire 25 is fixedly connected to the connection block 22, and then the outer end of the connection wire 25 is fixedly connected to the battery cell 13 on the side, so that the connection block 22 and the display light 23 are electrically connected to the battery cell 13 through the connection wire 25.

[0049] When the solar panel is successfully installed and put into use, the indicator light 23 is on, indicating that the battery cell 13 connected to the indicator light 23 is in use. When a battery cell 13 is damaged, the corresponding indicator light 23 is turned off. The staff can know which battery cell 13 is damaged or stopped using by observing the indicator light 23.

[0050] In the above steps, the interaction between the indicator light 23 and the battery cell 13 can be used to determine whether the battery cell 13 is damaged.

[0051] See also Figure 1 , Figure 4 As shown, this embodiment is based on the above embodiment 1 and also includes:

[0052] The main assembly further includes a partition plate 12 fixed between each group of battery cells 13 and a frame 11 fixed between the peripheries of the battery cells 13;

[0053] The partition plate 12 separates each group of battery cells 13, and the frame 11 is used to fix the battery cells 13 inside;

[0054] The swing assembly includes a set of mounting plates 31 fixed to both sides of the bottom end of the frame 11, and a movable rod 32 movably connected to the outer side of the mounting plates 31;

[0055] The mounting plate 31 is fixed to the left and right sides of the bottom end of the frame 11. The mounting plate 31 is used to connect the movable rod 32.

[0057] A movable shaft 34 is movably connected at the connection between the movable rod 32 and the mounting plate 31;

[0058] When the movable rod 32 moves, the movable rod 32 drives the mounting nails 34 to swing and sweep the objects hung on the solar panel. The movable rod 32 swings through the movable shaft 33. There are a total of sixteen mounting nails 33 at the outer end of the movable rod 32, eight in each group.

[0059] Working principle:

[0060] When there is a bag hanging on the solar panel, the assembly is electrically connected to the solar panel, and the movable rods 32 on both sides begin to swing to the left together, and the movable rods 32 drive the mounting nails 33 to swing through the movable shafts 34. When the mounting nails 33 pass through the bag, the movable rods 32 swing to the right, and the mounting nails 33 drive the bag to swing together, so that the bag leaves the solar panel. At the same time, during the swinging process of the movable rods 32, the bag leaves the movable rods 32, thereby realizing the moving and cleaning of the objects hanging on the solar panel;
