Sun Power: How Angles Impact Solar Cells | Science Fair Projects | STEM Projects
Ever wanted to know how the angle of the sun affects the power output of a solar cell? In this experiment, you will use solar cells to measure the power output at different angles of incidence of sunlight.

Hypothesis

The hypothesis is that the power output generated by a solar cell will be highest when the solar cell is positioned perpendicular to the direction of sunlight.

Method & Materials

You will use 7 polycrystalline solar cells, 7 wooden cubes, a protractor, double-sided tape, a digital voltmeter, an ammeter, and a resistor to measure the power output of the solar cells at different angles.
You will need 7 polycrystalline solar cells, 7 wooden cubes, a saw, a protractor, double-sided tape, a digital voltmeter, an ammeter, and a resistor.

Results

The results show that the solar cell mounted perpendicular to the sunlight has the highest power output and this output continues to decline as the angle reduces to zero. This proves the hypothesis to be correct.

Why do this project?

This science project is interesting because it shows how the angle of the sun affects the power output of a solar cell. It also demonstrates how a solar tracker can be used to optimize the performance of a solar cell.

Also Consider

Consider repeating the experiment using amorphous solar cells. Also, try to simulate real life as much as possible by introducing elements such as wind, water (rain) and ice to the test environment.
