The fan speed is controlled by the intensity of the sun collect by the solar panel.
This kit provides a rudimentary demonstration for how solar energy works.Technical Specificationsâ€¢Power Source: Solar panel
â€¢Solar panel: 4 VDC, 60 mA
â€¢Solar panel dimensions: 2.36 x 2.36 inches
Operating Principles:When the solar panel is facing sunlight, it will convert the sunÃ¯Â¿Â½s energy to DC voltage.
The DC voltage will be utilized by the DC motor to turn the fan.
Fan speed will be determined by the intensity of the sun collected by the solar panel.
