Solar fan and its working principle

The solar fan's structure includes main components such as fan blades, a motor compartment, a battery compartment, and a back cover. The motor compartment houses the motor, and the battery compartment houses the battery, with a voltage regulator circuit board located in between. The motor is connected to the fan blades via a connecting rod. It comes equipped with a detachable, small, folding tripod, supporting both upright and handheld operation.

The solar panel charges the battery. In sufficient sunlight, the solar panel generates current and voltage to charge the battery. The battery then supplies electrical energy to the load. The motor is connected to the fan blades via the connecting rod.
