Block D Group 1 1. Question: How does the Angle of a PV Cell to a light Source Affect the Electrical Output?

2. Hypothesis: If you increase the angle of the PV Cell to a light source, the it will increase the electrical output.

3. Materials needed:
 * PV Cell
 * Light
 * Alligator clamps
 * Multimeter
 * Protractor

4.Procedures
 * 1) Hook the two alligator clamps to the PV Cell
 * 2) Set angles at every 45 degrees by piveting the PV cell
 * 3) Connect the multimeter to each of the alligator clamps
 * 4) Markdown in the data table the electrical output at each angle.

5.Data Table

Voltage Angle Data Table
 * Angle (Degrees) || Output (Volts) ||
 * 0 || 2.6 ||
 * 45 || 3.3 ||
 * 90 || 4.05 ||
 * 135 || 5.32 ||
 * 180 || 5.5 ||

7. Conclusion
 * Our data supported our hypothesis, " If you increase the angle of the PV Cell to a light source, the it will increase the electrical output." because every 45 degrees the PV cell was piveted it increased the electrical ouput.
 * Based on our results the best position to put the Photovoltaic cells is directly at 180 degrees or facing straight up at the sun.

8. Problems with lab
 * Trying to get the exact angle from the protractor to the PV cell
 * Hurrying up and writing down the exact ouput
 * If we had to do it over, we would change the way we put the alligator clamps because it was difficult to get the exact angle from the protractor with the alligator clamps in the way.
