Thus, by adjusting the number or connection manner of the solar blades 100, the size and area of the solar curtain device 10 can be changed according to the size limitation of different light receiving surfaces, and the solar curtain device can be applied to light receiving positions in different outdoor or indoor spaces, so as to widen the use scene, further increase the lighting area, and improve the energy utilization efficiency.

The master control circuit 220 may be mechanically connected to the solar blade 100 and drive the solar blade 100 to rotate, translate, etc. so as to make the solar blade 100 have an optimal lighting area. Meanwhile, the master control circuit 220 may further be communicatively and/or electrically connected to the solar blades 100 to obtain working parameters of each solar blade 100, where the working parameters include, but are not limited to, a working state, a position, a current angle, a power generation voltage, a power generation current, and the like of the solar blade 100.

The general control circuit 220 is further connected to the light tracker 210, and the light tracker 210 can be used to detect brightness, and can be fixed at any position, and only needs to detect sunlight, for example, the light tracker 210 can be arranged on any blade, and also can be arranged on a window or other equipment.
