Turn the classroom into a physics lab
The photovoltaic experiment set, newly developed with the expertise of physics teachers, shows secondary school students how photovoltaics work
4 experiments for all grade levels
Experiment 1 is basically suitable for all grades and can also be used in subjects such as geography or ethics.
Experiments 2, 3 and 4 are intended for demanding physical experiments in grades 8 to 11.
The extra large photovoltaic modules, the ease of use and the solid construction provide security when experimenting, especially in the lower grades.
Experiment 1
Optimal inclination angle between
module and light source
Learning goal
Optimum alignment of photovoltaic modules in theory and practice.
Description
In this experiment, two angles 𝑎 and 𝛾 are examined using a movable solar module. The values of 𝑎 and 𝛾 are to be determined under which the module delivers the greatest power.
Experimental setup
-
Base plate with integrated consumers (4 LEDs) and plugs
-
Photovoltaic module (max. 20 VDC) with bracket, movable in 2 axes included
-
cabling
-
angle washer
-
Bulb holder, with spacer line
-
LED bulbs
-
multimeter (1)
-
Cable (2)
Experiment 2
Series and parallel connection of
photovoltaic modules
Learning goal
Confirmation of Kirchhoff’s knot and mesh rules. Derivation of the optimal connection of the photovoltaic modules.
Description
Series and parallel connection with 2 photovoltaic modules. It should be confirmed that in series the terminal voltages of the modules add up, but the currents remain the same, in parallel the currents add up and the terminal voltages remain the same.
Experimental setup
-
Base plate with mount for the photovoltaic modules and integrated potentiometer and plugs
-
2 photovoltaic modules (max. 2 x 20 VDC) including cabling
-
bulb holder
-
Halogen bulbs
-
multimeter (1)
-
cable (2)
Experiment 3
Maximum-Power-Point from a PV-Modul
Learning goal
In this experiment, the I-V characteristic of the solar cells is to be drawn in order to determine the optimal operating point of a PV module, the "MPP".
Description
A simple circuit is built with a photovoltaic module and a 220 Ω potentiometer. While varying the resistance, the changes in voltage and current are to be noted at the same time and the characteristic curves are to be recorded.
Experimental setup
-
Base plate with mount for the photovoltaic module and integrated potentiometers, fan and plugs
-
PV module (max. 20 VDC) including wiring
-
bulb holder
-
Halogen bulbs
-
multimeters (2)
-
cable (4)
Experiment 4
Quality and efficiency of one
photovoltaic module
Learning goal
In this experiment, the maximum efficiency of a photovoltaic module is to be determined and its change due to an increase in temperature is to be examined.
Description
With a lux meter, a set square/ruler and a multimeter, characteristic values of the module in the circuit are to be recorded and the efficiency of the module is to be examined quantitatively and qualitatively using simple formulas.
Experimental setup
-
Base plate with mount for the photovoltaic module
-
PV module (max. 20 VDC) including wiring
-
bulb holder
-
Halogen bulbs
-
multimeter
-
hairdryer
Price for the set

incl. 7% VAT,
plus shipping and handling
540 € (one exp.)
The complete set is suitable for 16 students. It consists of 8 experiment stations (2x per experiment) where two students can work at the same time. Each experiment is available twice.
The experimental set is produced by the Bruck workshop for people with disabilities in Fürstenfeldbruck of the Caritas Association of the Archdiocese of Munich and Freising eV.
When selecting materials and components, special emphasis was placed on usability as well as recyclability and repairability.
The delivery time is approximately 3 months from receipt of the order. Delivery costs are not included in the price.
The experiment set was registered as a utility model with the German Patent and Trademark Office under the number 20 2022 106 397.
