[0021] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0022] Please see Figure 1 and Figure 2The photovoltaic louver 1000 includes multiple photovoltaic blades 1, a connecting assembly 2, and a flexible cable 3. The multiple photovoltaic blades 1 are arranged sequentially along a first direction X. Each photovoltaic blade 1 includes a blade body 11 and a photovoltaic cell 12, with the photovoltaic cell 12 fixed to the blade body 11.

The telescopic bracket is connected to a driving device, which drives the telescopic bracket to extend and retract along a direction parallel to the first direction X, thereby causing adjacent photovoltaic blades 1 to move away from or closer to each other in a direction parallel to the first direction X. The number of rotating shafts is the same as the number of photovoltaic blades 1 and they are arranged in a one-to-one correspondence. The rotating shafts are disposed on the telescopic bracket, and one photovoltaic blade 1 is connected to one rotating shaft. The driving device is connected to each rotating shaft and is also used to drive the rotating shaft to rotate, thereby causing the photovoltaic blade 1 to rotate and thus changing the angle of the photovoltaic blade 1.

[0074] In some embodiments, the mounting cover 8 is provided with a slide rail (not shown), and the telescopic bracket is provided on the slide rail. The slide rail is used to support the telescopic bracket, and the telescopic bracket can slide relative to the slide rail when it extends or retracts.

[0075] Based on the same inventive concept, this application also provides a photovoltaic power generation system, including the photovoltaic louver 1000 in any of the above embodiments.

[0076] In some embodiments, the photovoltaic power generation system includes a microinverter (not shown). The microinverter is electrically connected to a plurality of photovoltaic blades 1 and is used to convert the direct current generated by the plurality of photovoltaic blades 1 into alternating current.

[0077] In some embodiments, the photovoltaic power generation system includes an energy storage power source for storing the direct current output by the photovoltaic louvers 1000.

[0078] Please see Figure 1 and Figure 7 In some embodiments, the microinverter is mounted on a fixed frame 5 or a mounting cover 8. Taking the microinverter mounted on a fixed frame 5 as an example, the fixed frame 5 is also provided with a third connector (not shown) and a fourth connector (not shown). The third connector and the fourth connector are electrically connected to the microinverter. Along the first direction X, the first connector 22 of a transfer component 2 of the photovoltaic blade 1 located at the first end is connected to the third connector through a flexible cable 3. The first connector 22 of another transfer component 2 of the photovoltaic blade 1 located at the first end is connected to the fourth connector through another flexible cable 3. In this way, multiple photovoltaic blades 1 are electrically connected to the microinverter.

[0079] The above are merely embodiments of this application and do not limit the patent scope of this application.
