High School

Two students created and tested a solar panel model for their tree house. They aimed to generate the maximum amount of electricity to power their appliances. Which of the following is a potential revision they made to their solar panel model, and why?

A. Test the solar panel during afternoon hours instead of in the morning.
B. Increase the surface area of the solar panel to capture more sunlight.
C. Decrease the surface area of the solar panel to capture less light.
D. Test the solar panel during the summer instead of the winter to receive more light.

Answer :

Final answer:

Students can increase the efficiency of their solar panel by increasing its surface area, testing it during afternoon hours, or during the summer months when there are more sunlight hours. Both methods aim to increase the amount of light incident on the panel, thereby generating more electricity.

Explanation:

The student could potentially make a few modifications to generate more electricity from their solar panel model. Firstly, they could increase the surface area of the solar panel to capture more sunlight. A larger surface area would allow for more photons to be absorbed by the panel, thus producing more electricity. This is in line with the principle of photovoltaic cells where energy carried by sunlight is captured and directly converted into electricity.

Secondly, they could also revise their testing times and try experimenting during afternoon hours instead of just in the morning or during the summer when there are more sunlight hours compared to winter. Both of these methods increase the incident light on the panel, thus potentially generating more electricity. Remember, the efficacy of solar power is influenced by factors like cloud cover, nightfall, and the angle at which light hits the panel.
