Turn the classroom into a physics lab

The photovoltaic experiment set, newly developed with the expertise of physics teachers and successfully presented at the German Physical Society, clearly shows schoolchildren how photovoltaics works.

Science kit experiment 2

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.



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.



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".



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)

PV-Experimente-Set Versuch 4
Science kit experiment 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.



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

3300 €

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), on which two students can work at the same time. Each experiment is duplicated.


The learning game is produced by the Brucker workshop for people with disabilities Fürstenfeldbruck of the Caritas Association of the Archdiocese of Munich and Freising e.V..

When selecting the materials and components, special emphasis was placed on recyclability and repairability in addition to operability.

The experiment set comes with detailed "play instructions" for carrying out different experiments. These documents can also be found online in our teaching materials library.

Institutions that purchase the PV Experiments Kit receive free access to the Solar for Kids Education online teaching materials for elementary school and the last year of kindergarten

The delivery time is approx. 3 months from receipt of order. Delivery costs not included in the price. 

It is possible to purchase the experiments individually. The single price is 540€ for each experiment set (1 to 4).
