 * 1. Question- How Does Combining PV Cells in Series Affect the Electrical Output of the PV Panel?**


 * 2. Hypothesis- If more solar cells are added to the series circut, then the voltage will increase.**


 * 3.Materials-**
 * **5 solar cells**
 * **ringstand to hold light, height 30 cm**
 * **one incondescent light bulb 75 watt**
 * **one multimeter**
 * **one meterstick**
 * **6 alligator clips**
 * **stop watch**


 * 4. Procedure- 1. Connect five PV panels in a series circut with alligator clips. 2. Put 75 watt incandescent bulb a measured distance of 30 centimeters away from the PV panels. 3. Hook the end of the series circut to the DVOM. 4. turn DVOM to V== 200 and collect and report your data after 30 seconds. 5. Repeat, taking one PV panel away for each trial. 6. Collect and record all data.**


 * 5. Data Table-**
 * Solar cells in a series || Multimeter readings (volts) ||
 * 1 || 5.37 ||
 * 2 || 10.72 ||
 * 3 || 14.56 ||
 * 4 || 19.63 ||
 * 5 || 24.6 ||


 * 6. Hand made. (:**


 * 7. Conclusion- Our data supported our hypothesis - IF you add more solar cells in a series, THEN the voltage will increase. In order to get enough energy to use in your house, your going to have to make a series circut of PV panels by connecting them continueing to add more PV panels.**


 * 8. Problems- What we would do differently next would be to make sure al the solar panels work first. A light bulb was used instead of the sun, we could have kept the panels under the light for longer before we record the data, not all of the panels were under direct light.**
