Solar Panel Angle Experimental Design:
Question: What is the effect of the solar panel’s angle on the amount of energy collected?
Hypothesis: If the angle is 45 degrees, then the amount of energy collected will be at maximum amount.
Independent Variable: Angle of the solar panel (degrees)
Levels of Independent Variable and Trials
[Some extra angles were added (30 and 60 degrees, and edge)]
Level 1: 0 degrees indoors and outdoors 3 trials each
Level 2: 45 degrees indoors and outdoors 3 trials each
Level 3: 90 degrees indoors and outdoors 3 trials each
Dependent Variable: Energy collected (direct current voltage)
Constants: Spot placed, time for each trial, stand, solar cell
Control Group: Indoors
Materials:
· Clock/timer
· Solar cell
· Stand
· Multimeter
· Protractor
· Data sheet
Procedures:
1. Obtain solar panel.
2. Observe and record weather.
3. Place solar panel onto designated spot.
4. Adjust angle solar panel is facing using protractor.
5. Leave out for 30 seconds.
6. Check how much energy was collected on multimeter.
7. Record information on spreadsheet.
8. Repeat steps 1-7 for 3 trials indoors and outdoors.
9. Repeat steps 1-8 for the other levels of independent variable.
