Description
Photovoltaic solar modules convert sunlight directly into electrical current and are therefore an ideal component for renewable energy supply. Typical solar modules from the field of photovoltaics are made of several silicon solar cells connected in series.
The trainer contains two such solar modules. The inclination of the modules can be adjusted. Cables can be used to connect the two modules in series or in parallel. A slide resistor simulates varying loads. Thus the slide resistor makes it possible to record current-voltage curves.
The separate measuring amplifier provides displays for all relevant variables. Two power resistors in the measuring amplifier are used to expand the measuring range for measurements at low illuminance. Sensors on the solar module detect illuminance and temperature.
In order to ensure there is sufficient illuminance, the trainer should be operated with sunlight or the optionally available artificial light source.
