[0072] like Figure 4 As shown, the support portion 310 and the connecting portion 320 are connected.

[0073] The support part 310 is provided with a groove 311.

[0074] In this embodiment, the groove 311 opens upwards, and the connecting part 320 is connected to the bottom outer wall of the support part 310, which can adjust the tilt angle of the photovoltaic module 100 to a large extent.

[0075] The connecting part 320 is connected to the connecting rod 400.

[0076] The connection between the connecting part 320 and the connecting rod 400 can be achieved by various connection methods, such as snap-fit, bolt connection, welding and hinge.

[0077] In this embodiment, the connecting part 320 and the connecting rod 400 are hinged, and the angle is adjustable.

[0078] The diagonal brace 200 is installed in the groove 311.

[0079] The diagonal brace 200 and the groove 311 can be connected in various ways, such as snap-fit, bolt connection, welding and hinge.

[0080] In this embodiment, the diagonal bar 200 and the groove 311 are connected by bolts, which has high connection strength, good stability, and is easy to disassemble and assemble.

[0081] According to the photovoltaic system 1000 provided in the embodiments of this application, by providing a groove 311 in the support portion 310 of the support member 300 and installing the inclined rod 200 in the groove 311, the stability is better, and by connecting it to the connecting rod 400 through the connecting portion 320, the angle can be adjusted to a wider range.

[0082] In some embodiments, the width of the connecting portion 320 may vary.

[0083] like Figure 5 As shown, in this embodiment, the width of the connecting part 320 gradually increases along the direction close to the hinge area with the connecting rod 400, and the connecting part 320 is a plate structure. The variable cross-section plate can adapt to the internal force distribution of the cantilever member and play the role of strengthening the diagonal rod 200.

[0084] In some embodiments, the cross-section of the connecting portion 320 may also be rectangular.

[0085] According to the photovoltaic system 1000 provided in the embodiments of this application, by setting the connecting part 320 as a variable cross-section flat plate structure with a width that gradually widens in the direction close to the hinge area with the connecting rod 400, the internal force distribution of the cantilever member can be adapted to improve the strength of the diagonal rod 200.

[0087] The first rod at 420 is positioned outside the second rod at 430.

[0088] like Figure 6 As shown, the first rod 420 is provided with a first positioning hole 421, and the second rod 430 is provided with a second positioning hole 431. The first positioning hole 421 and the second positioning hole 431 are provided correspondingly.

[0089] The first rod 420 and the second rod 430 are connected to the second positioning hole 431 through the first positioning hole 421.

[0090] In this embodiment, the first positioning hole 421 and the second positioning hole 431 can be at least one of the following structural forms:

[0091] Firstly, there is one first positioning hole 421 and multiple second positioning holes 431.

[0092] In this embodiment, by selecting one of the multiple second positioning holes 431 to connect with the first positioning hole 421, the length of the first rod 420 after the connection of the second rod 430 is changed, the tilt angle of the inclined rod 200 is adjusted, and thus the tilt angle of the photovoltaic module 100 is changed.

[0093] Secondly, there are multiple first positioning holes 421 and one second positioning hole 431.

[0094] In this embodiment, by selecting one of the multiple first positioning holes 421 to connect with the second positioning hole 431, the length of the first rod 420 after the connection with the second rod 430 is changed, the tilt angle of the inclined rod 200 is adjusted, and thus the tilt angle of the photovoltaic module 100 is changed.

[0096] In this embodiment, by selecting some holes in a plurality of second positioning holes 431 to connect with some holes in the first positioning hole 421, the length of the first rod 420 after the connection of the second rod 430 is changed, the tilt angle of the inclined rod 200 is adjusted, and thus the tilt angle of the photovoltaic module 100 is changed.

[0097] The inclined rod 200 is hinged to the first connecting structure 210, the first rod 420 is hinged to the second connecting structure 410, and the second rod 430 is hinged to the support member 300, so that when the first positioning hole 421 and the second positioning hole 431 are connected, the inclined rod 200 rotates around the first connecting structure 210, the first rod 420 rotates around the second connecting structure 410, and the second rod 430 rotates around the support member 300, thereby adjusting the tilt angle of the inclined rod 200 and the photovoltaic module 100.

[0098] According to the photovoltaic system 1000 provided in the embodiments of this application, by providing a first positioning hole 421 on the first rod 420 and a second positioning hole 431 on the second rod 430, different first positioning holes 421 or second positioning holes 431 can be selected for connection when the first rod 420 is sleeved on the second rod 430, thereby changing the length of the connecting rod 400 and adjusting the tilt angle of the inclined rod 200.

[0114] In some embodiments, such as Figure 8 As shown, the frame 120 may be provided with a mounting plate 122.

[0115] Mounting plate 122 is installed at the bottom of frame 120.

[0116] Mounting plate 122 is connected to diagonal brace 200.
