Using the teaching unit "Investigations on PV cells" , students experience the interplay between theory, experiment and technical application using the school's own PV system or the Solar Education PV experiment set or the PV teaching equipment system.
A comprehensive teaching unit covering the fundamental topics of photovoltaics: from the physical operating principle and components of a real PV system, to various experiments and the role of...
Energy transition in photovoltaics. If available, there will also be a "digital field trip" to the school roof, where students can experience the school's own PV system live (i.e., the PV livestream lesson is part of this lesson).
This fosters the development of process-related skills in the areas of knowledge acquisition, communication, and evaluation. The focus is on the Solar Education experiment kit and the PV livestream lesson. Students learn fundamental knowledge through theoretical units, validate this knowledge through self-conducted experiments, and establish valuable practical connections through interaction with a technician.
The PV experiment kit or the PV teaching system from Solar Bildung is required for this. Alternatively, the school's own PV system can be used instead of the PV teaching system, if available.

We would like to express our sincere thanks to the Solarförderverein Bayern eV for their financial support in the development of this learning unit.
We always strive to thoroughly check our lessons for potential errors before publication. However, should you, our valued user, notice anything, we would appreciate a message to fehlerteufel@solarbildung.org
Investigations on PV cells
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.
