[0022] See Figure 1As shown in the figure, there is a mounting plate buckle for a shedless photovoltaic array. Among them, four buckles 1 are grouped together and are respectively located on the frames 3 on the opposite sides of the photovoltaic panel 2; one side of each buckle 1 is fixedly connected to the frame 3 of the photovoltaic panel 2; at least one mounting hole 4 is provided on each buckle 1; bolts are used to connect the mounting holes 4 of the buckles 1 on the adjacent sides of two photovoltaic panels 2, so as to quickly install a number of photovoltaic panels 2 into a photovoltaic array. The solution of this embodiment is to provide buckles 1 on the frame 3 on the side of the photovoltaic panel 2. Multiple photovoltaic panels 2 are connected through the mounting holes 4 on the provided buckles 1 and are connected to the screw piles fixed on the bearing object to form a photovoltaic array. The technical solution of this embodiment simplifies the process, shortens the installation period, and reduces the installation cost because it does not require devices such as sheds and cement bases.

[0023] For another example Figure 1 and Figure 2 As shown in the figure, generally two buckles 1 are provided on each of the opposite sides of the photovoltaic panel 2. However, according to the size of the photovoltaic panel 2 or other actual situations, the number of buckles 1 provided on each side of the photovoltaic panel 2 can also be other numbers.

[0024] Generally speaking, there are two ways to fix the buckle 1 to the photovoltaic panel 2, that is, welding or riveting the buckle 1 to the frame 3 of the photovoltaic panel 2. These two methods can be completed in the assembly workshop of the photovoltaic panel 2.

[0025] The buckle 1 is preferably made of a bendable metal plate, so that it can not only bear the weight of the photovoltaic panel, but also meet the requirements of the required bending angle and system stability.

[0026] The buckle 1 can be subjected to anti-corrosion treatment such as hot-dip galvanizing to achieve the purpose of extending its life.

[0027] See Figure 3As shown, the plate fasteners 1 on one side of the photovoltaic panel 2 are bent in the same direction, while those on the opposite side are bent in the opposite direction; the upward-bent plate fasteners 1 of two adjacent photovoltaic panels 2 are connected by bolts, and the downward-bent plate fasteners 1 of two adjacent photovoltaic panels 2 are connected to the screw piles fixed on the ground or other bearing objects. Currently, the panels of the photovoltaic array are all in the same plane and inclined at a certain angle. The problems are as follows: First, the sunlight reflected by the solar panels cannot be reused by other panels; second, the dust on the solar panels can only slide in one direction, and the self-cleaning ability is poor. By adopting the technical solution of this embodiment, not only is the whole inclined at a certain angle, but also they are in a bent W shape with each other. The advantages are: on the one hand, the sunlight reflected by one solar panel may be reused by another panel, thus improving the utilization efficiency of sunlight; on the other hand, the solar panels are actually inclined in two directions, which is more conducive to the sliding of the dust on them and improves the self-purification ability of the photovoltaic array.

[0028] See Figure 1 As shown, the plate fastener 1 includes a fixing plate 5 and a mounting plate 6, and the fixing plate 5 and the mounting plate 6 are bendably connected. The fixing plate 5 is fixedly connected to the frame 3 of the photovoltaic panel 2, and the mounting hole 4 is arranged on the mounting plate 6.
