A solar fan is a fan that operates using solar energy. It uses solar panels or solar photovoltaic cells to convert solar energy into electrical energy, which then drives the fan. These fans usually have a portable design for outdoor use and do not require an external power source.

The working principle of a solar fan is simple. The solar panel converts sunlight into DC electrical energy, which is either stored in the built-in battery or supplied directly to the fan motor. The electrical energy is used to drive the fan blades through the motor to generate wind power. Some solar fans also have a charging function that allows them to charge other devices, such as cell phones and tablets, through the solar panel.
