Item RG023003: Changes in both the brightness of sunlight and the amount of time sunlight shines on solar panels will change the amount of energy transferred.
A house has solar panels on its roof. The solar panels absorb light from the sun and use it to produce electricity for the house. They are designed to absorb the maximum amount of energy throughout the year for that location.
The brightness of the sunlight and the amount of time the sunlight shines on the panels change from day to day. Will these changes affect how much energy is transferred from the sun to the solar panels?
- Yes, changes in both the brightness of the sunlight and the amount of time the sunlight shines on the panels will change the amount of energy transferred.
- Yes, changes in the brightness of the sunlight will change the amount of energy transferred, but changes in the amount of time the sunlight shines on the panels will not.
- Yes, changes in the amount of time the sunlight shines on the panels will change the amount of energy transferred, but changes in the brightness of the sunlight will not.
- No, changes in the amount of time the sunlight shines on the panels and changes in the brightness of the sunlight will not change the amount of energy transferred.
