Block D Group 6

1. QUESTION - How does combining PV cells in series affect the electrical output of the PV panel?

2. HYPOTHESIS - IF you add more PV cells with series THEN the electrical output will increase.

3. MATERIALS NEEDED - 5 solar panels Aligator clips (enough for 5 solar panels) Ring stand 100 W incadescent bulb Multimeter

4. PROCEDURE - 1. Set the lightbulb on the ring stand so it can shine on the solar panels 2. Have the multimeter set to 20 the entire time. 3. Connect the wires from the multimeter to a solar panel, record data 4. Use additional alligator clips to connect to the 2nd solar panel, record data. 5. Continue doing so until you have all 5 panels hooked together.

Keep in mind that the light should be on the entire time. Conclusion: As the number of PhotoVoltaic cells increases,the number of voltage decreases. Problems: The problems I endourded were of insufficent lamplight to support all 5 PV cell boards. Also the problem could have been related to a falty PV board after PV3.
