According to some embodiments of the present invention, referring to fig. 8-10, the first support table 103 and the second support table 105 are both disposed obliquely with respect to the first support 101. When the mounting bracket 10 is applied to the photovoltaic system 100, the photovoltaic module 20 is obliquely placed on the first supporting platform 103 or the second supporting platform 105, so that the contact area between the first supporting platform 103 and the photovoltaic module 20 and the contact area between the second supporting platform 105 and the photovoltaic module 20 can be increased, the photovoltaic module 20 can be more reliably connected to the mounting bracket 10, and the reliability of the photovoltaic system 100 is improved.

Wherein a stop may be provided on one of the first support table 103 and the second support table 105; alternatively, the first support base 103 and the second support base 105 may be provided with stoppers. Therefore, the stopping portion can serve as a limiting function, and when the photovoltaic module 20 is installed, the photovoltaic module 20 can be pre-placed on the first supporting platform 103 or the second supporting platform 105 to prevent the photovoltaic module 20 from sliding off or separating from the first supporting platform 103 and the second supporting platform 105 after bearing a load.

Further, the blocking portion includes at least one first blocking portion 1031, and the first blocking portion 1031 is disposed at one end of the first supporting platform 103 with a lower height. For example, in the example of fig. 3, 6 and 9, there are two first stoppers 1031, two first stoppers 1031 are respectively located on both sides of the second holder 102, and each first stopper 1031 is formed by bending an edge of the lower end of the first support table 103 in a direction away from the first holder 101. So set up, can further fix photovoltaic module 20 on first supporting bench 103 steadily to can further guarantee the stability of photovoltaic module 20's position, first backstop 1031's preparation method is simple simultaneously, makes things convenient for first backstop 1031's processing.

According to some embodiments of the present invention, the stops comprise at least one second stop 1051, the second stop 1051 being arranged in the middle of the second support 105 along the length of the first support 101. As shown in fig. 4, 7, and 10, the number of the second stoppers 1051 is two, and the two second stoppers 1051 are provided on both sides of the second support base 105 in the width direction. For example, the second support base 105 is formed with a notch 1052, one end of the second stopper 1051 is connected to one of the sidewalls of the notch 1052 in the longitudinal direction of the first bracket 101, and the other end of the second stopper 1051 is bent away from the first bracket 101. Thus, mounting the photovoltaic module 20 on the second mount 105 can increase the contact area of the second stopper 1051 with the frame of the photovoltaic module 20 to prevent the photovoltaic module 20 from sliding off the second mount 105.

In some alternative embodiments, as shown in fig. 3 and 4, the height of the stop is H ₁ Wherein H is ₁ Satisfies the following conditions: h is not less than 3mm ₁ Less than or equal to 5 mm. When H is present ₁ When the height of the stopping part is less than 3mm, the stopping part has a poor limiting effect, and the photovoltaic module 20 may slide off the first supporting table 103 or the second supporting table 105; when H is present ₁ If the thickness is greater than 5mm, since the stopper is formed by bending a portion of the first supporting base 103 or a portion of the second supporting base 105, the height of the stopper is high, which may reduce the contact area between the first supporting base 103 or the second supporting base 105 and the photovoltaic module 20, thereby affecting the stability of the photovoltaic module 20. Thereby, by making H ₁ Satisfies the following conditions: h is not less than 3mm ₁ Be less than or equal to 5mm, guarantee that backstop portion has better limiting displacement, and can prevent that photovoltaic module 20 from first brace table 103 or second brace table 105 from the landing, guaranteed photovoltaic module 20's stability.

Thereby, the position of the second mount 105 and the third support 104 can be ensured to be stable, so that the photovoltaic module 20 can be stably mounted on the second mount 105.

Further, as shown in fig. 2, an included angle between the second supporting stage 105 and the horizontal plane is α, where α satisfies: alpha is more than or equal to 10 degrees and less than or equal to 30 degrees. With the arrangement, the photovoltaic module 20 can be ensured to have an optimal incident angle, so that more sunlight can be received, and the photoelectric conversion efficiency of the photovoltaic module 20 is increased.
