Descriptions:
This hat is powered by a polysilicon panel. The photoelectric conversion efficiency of polycrystalline silicon panels is 1.5 to 1.8 times that of amorphous silicon panels, so the fan speed and wind power are also dependent on the intensity of sunlight.
Compared to floor fans, this solar fan's leaves are not so big, the wind is relatively small, and the wind can only blow your face.

Features:
1. Powered by solar panel, no need of extra batteries or power; as long as there is a sun, it can power the fan and not as heavy as a traditional fan hat.
2. The fan will start automatically as long as it is under strong sunlight. The small fan will automatically stop running indoors or in the dark;
3. Novel, fashionable, peculiar, practical, energy-saving and environment friendly.
