Solar Fan
Model GSK-1001
This circuit converts sunlight into electrical energy. 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 Specifications
nPower Source: Solar panel
nSolar panel: 4 VDC, 60 mA
nSolar panel dimensions: 2.36 x 2.36 inches
Operating Principles
When the solar panel is facing sunlight, it will convert the
sun’s 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 collect by the solar panel.
Circuit Assembly
Please refer to Figures 2 for aid in circuit assembly.
Note
This solar panel will not convert fluorescent light to DC voltage.
Special handling instruction
Extra care must be taken to ensure proper installation of
solar panel to PCB. Severe damage may occur to the solar
panel if the positive and negative poles are short circuited.
Testing
Connect all components as shown in figure 2. Make sure
the red clip is connected to the positive pole and the black
clip to the negative pole. If the connections are reversed, the
fan will turn in reverse direction. The motor (fan) will turn
faster the greater the suns intensity and slow or stop moving
with less or no sun light.
Troubleshooting
The solar panel may be tested by connecting the positive pole
and negative pole to a voltmeter. Turn the solar panel towards
the sun, and any movement displayed by the voltmeter
indicates the solar panel is functional. To test the DC motor,
connect a 3 VDC power source to the motor. If the motor
turns, it is working.
