Block D Group 2

1.) Question Solar 5: How does placing part of a PV cell in shadow affect its electrical output.

2.) Hypothesis If half the PV cell gets covered then the energy it creates will also be cut in half.

3.) Materials needed PV cell, Aligator clamps, 100 watt light, multimeter, note card, meter stick

4.) Procedure 1. Hook up the aligator clamps to the PV cell and the multimeter 2. Use the meterstick to measure from the floor up to the lightbulb, 20cm 3. Place the PV cell under the 100 watt light and record the number of volts 4. Repeat step 3 four more times but covering up 1/5 of the PV cell for each new reading. 5. Record All your data in your data table.

5.)
 * PV Module Covered || Voltage (V) ||
 * 0 || 5.25 ||
 * 1/5 || 4.80 ||
 * 2/5 || 4.54 ||
 * 3/5 || 4.33 ||
 * 4/5 || 4.14 ||
 * 1 || 3.61 ||

6.) Conclusion the results are not supportive to the hypethesis, voltage did not drop by half of the starting voltage. if you have a photovoltaic panel, sometimes the sun is blocked by clouds, therfore causing it to produce less electricity. 7.) Problems Use more PV Cells to get more accurate readings. use the sun to activate te PV cell instead of a lamp.
