When sunlight hits a solar panel, the energy of the sun is transferred to the electrons that make up the solar panel. This causes the electrons to start moving through the wires connected to the panel. In this experiment, you will use a Vernier Energy Sensor to measure the electrons as they move. Three values are used to measure the movement of electrons: current, potential difference, and power.


  • Set up the data-collection equipment.
  • Measure current, potential difference (voltage), and power output of a Solar Panel with a Vernier Energy Sensor.
  • Use data-collection software to calculate mean (average) values.
