Electricity Science Fair Project

Maximizing Solar Energy

Medium
Maximizing Solar Energy | Science Fair Projects | STEM Projects
Let's find out if the angle of the sun's rays affects the power produced by a solar cell. The hypothesis is that if the solar cell is placed perpendicular to the sun's rays, the power going to the cell will be maximized.

Hypothesis

The hypothesis is that if the solar cell is placed perpendicular to the sun's rays, the power going to the cell will be maximized.

Method & Materials

You will set up a fan and a solar cell on a board, then move the board to different angles with the sun and measure the voltage going to the cell.
You will need a solar cell, three boards, a fan, a voltage meter, string, two screws, and a protractor.

Results

The results of the experiment showed that when the cell was perpendicular to the ground, the energy was 4/5 volts. When it was at a right angle to the sun, however, it measured 3/5 volts. At other angles, it measured from 0 to 4/5 volts. This data suggests that the hypothesis is not accurate.

Why do this project?

This science project is interesting because it explores the potential of solar energy as an alternative source of energy.

Also Consider

Experiment variations to consider include testing the effect of different types of solar cells on the power produced, or testing the effect of different weather conditions on the power produced.
