Figure 3 is a detailed view of the head guide rail and the head in the cleaning and cooling apparatus of the solar panel according to an embodiment of the present invention.

Referring to FIG. 3, the head guide rail 200 has an approximately C-shape, and is provided at the upper side of the lower surface 200a and the extension portion 200b and the extension portion 200b extending upward from the lower surface 200a. It has an upper surface 200c extending to one side.

On the other hand, an inner rail 210 is installed on the lower surface 200a of the head guide rail 200 so that the head 300 can slide well. Therefore, a sliding groove 220 is formed between the inner rail 210 and the upper surface 200c of the head guide rail 200.

In addition, the head 300 is guided to the sliding groove (220) formed in the head guide rail 200, the slider 310, and is installed on the slider 310, the head bracket 320 and the head bracket 320 It is provided with a head body 330 fixed to.
