This experiment was done to find out how changing the angle of incidence of sunlight throughout the day impacts the efficiency of a solar cell.
1. For this experiment, the independent variable is the angle of the solar cell. The dependent variable is the power output from the solar cell. This is determined by measuring the voltage and current produced. The constants (control variables) are the resistor, amount of sunlight, the temperature and the type of solar panel used. 2. The wooden blocks are cut with a saw in the workshop as shown in figure 1. The angles given below the drawings are measured using a protractor between the vertical line and the surface onto which the solar cell will be mounted. 3. This experiment .....
