[0002] Photovoltaic panels are a type of power generation device that generates direct current when exposed to sunlight. They are composed of thin solid photovoltaic cells made almost entirely of semiconductor materials (such as silicon). Since there are no moving parts, they can operate for long periods of time without causing any loss. Simple photovoltaic cells can provide energy for watches and computers, while more complex photovoltaic systems can provide lighting for houses and power the grid.

[0047] In summary, by setting the angle adjustment mechanism 3, the staff can remove the fixing bolt 323 from the adjustment rod 322, and then pull the adjustment rod 322 upward or push it downward to make the adjustment column 313 rotate on the column 312 and the adjustment rod 322, and the adjustment cylinder 321 rotates on the mounting plate 311, so as to realize and complete the angle adjustment operation of the photovoltaic panel body 4. Compared with the photovoltaic panel having one end hinged and the other end height-adjusted by the fixed support rod, the present device can adjust the photovoltaic panel to a relatively horizontal state. By setting the lifting adjustment mechanism 2, the lifting adjustment mechanism 2 can adjust the height of the adjustment plate 223 by the staff pulling the moving rod 222. The height adjustment of the adjustment plate 223 is prevented from being horizontally offset during vertical movement by the guiding action of the guide assembly 23. Finally, the insertion bolt 224 is inserted into the corresponding bolt hole 225 to complete the height adjustment of the photovoltaic panel. The adjustment method of the present device is manual adjustment, which is not only durable, but also simple to operate and easy to use.
