Summary
A detailed teaching unit on the basic topics of photovoltaics: from the physical operating principle and the components of a real PV system, to a wide variety of experiments and the role of the energy transition in photovoltaics. There is a "digital excursion" to the roof of the school, where the students experience the school's own PV system live.
With the help of the teaching unit Investigations on PV cells the students experience the interplay between theory, experiment and technical application using the school's own PV system. This enables them to acquire process-related skills in the areas of gaining knowledge, communicating and evaluating . The focus is on an experiment case and a PV livestream. The students learn basic knowledge through theoretical units, validate this through experiments they carry out themselves and establish valuable practical relevance through exchanges with a technician. The school's own PV system is therefore used as a teaching aid in addition to ecological and economic aspects.
The PV experiment set and the PV teaching equipment from Solar for Schools Bildung gGmbH are required for this. Optionally, instead of the PV teaching equipment, you can use the school's own PV system, if available.

Learning goals
Independently measure currents and voltages in series and parallel connections of solar modules.
Vary external influencing factors (e.g. angle of inclination, shading) and draw conclusions for the optimal use of solar modules, which they formulate, for example, in the form of an operating manual.
Testing the usability of solar modules in different technical applications.
Investigate experimentally the structure and properties of other sources of electricity (e.g. model experiment on the galvanic element, investigation of the output voltages of different power supplies, internal resistance and terminal voltage of a battery and a solar cell).
Interpret selected observations using their theoretical knowledge of electrical circuits.
