Aim- To make familiar with solar panel and its electrical output by running a small DC fan with the solar panel.
Components required-
1. Solar panel (6V, 200mA)
2. Diode (1N4007)
3. Small DC Fan (5V, 200mA)
Theory-
The solar panel generates electrical power when it is placed under the sun light. The output depends on the solar panel dimensions and solar radiation available to solar panel. The diode is unidirectional device. It conducts the current in one direction and blocks in the opposite directions. Due to this property diode is used to stop the reverse power flow toward the solar panel. The fan will work as load and will take electrical power generated from the solar panel to blow the air.
Steps-
1. Take the solar panel and put in the opposite way.
2. Find the + (plus) and – (minus) symbol on back side.
3. To the +side connect the black side of diode.
4. To the silver side of diode connect the fan + terminal (red wire).
5. Connect the –ve terminal (black wire) of Fan to the –ve side of solar panel.
6. Now take the solar panel in the sun light and put front side up. The fan will start running.
7. Now just put solar panel in different sun lights intensity and see the variation in the fan speed.
