How to reference this medium
Students will investigate the connection of solar cells in series and in parallel under load conditions. They will also learn how partial shading of solar cells affects the current and voltage.
One item deals with „Technical application and vocational orientation“.
Information and ideas:
The experiment requires prior knowledge of complex electrical circuits (in series, in parallel); see experiment “Vocational orientation 6.5”. It is recommended that students have conducted experiment 6.5 and that the learning outcomes of the experiments are reviewed.
When doing experiments with solar cells and electrical motors, bear in mind that the correlations become complex.
