Some days it is very sunny all day—there are no clouds in the sky, and it is very bright. In these conditions, lots of sunlight reaches the solar panels.
Other days it is cloudy. The sky might be completely covered in clouds or clouds may pass in front of the sun on and off during the day. Less sunlight reaches the solar panels on cloudy days.
Other things that could shade solar panels would be large trees next to houses or buildings. Do you think shade caused by trees or clouds will affect the power output of solar panels? In this experiment, you will use the Energy Sensor to help you answer this question.
Set up the data-collection equipment.
Measure the power output of three Solar Panels with a Vernier Energy Sensor.
Use data-collection software to calculate mean (average) values.
