Solar science kit

Turn the classroom into a physics lab

The solar experiment set from Solarbildung combines practical learning with state-of-the-art technology and makes complex physics concepts understandable through vivid experiments.

Experiment 1: Optimal tilt angle

Experiment 2: Series and parallel circuits

4 experiments for all grade levels

Experiment 1 is generally suitable for all grade levels and can also be used in subjects such as geography or ethics.

Experiments 2, 3, and 4 are designed for challenging physics experiments in grades 8 to 11. They fulfill core curriculum requirements in the area of "Using Models and Experiments" and can replace a regular physics assignment.

The extra-large photovoltaic modules, the ease of use, and the solid construction provide safety when experimenting, especially in lower grades.

Experiment 3: Maximum Power Point

Experiment 4: Quality and Efficiency

Optimal tilt angle between module and light source

Learning objective

Optimal alignment of photovoltaic modules in theory and practice.

Description

In this experiment, two angles, 𝑎 and 𝛾, are investigated using a movable solar module. The aim is to determine the values of 𝑎 and 𝛾 at which the module delivers the greatest power.

Series and parallel connection of photovoltaic modules

Learning objective

Confirmation of Kirchhoff's node and mesh rules. Derivation of the optimal interconnection of photovoltaic modules.

Description

A series and a parallel circuit with two photovoltaic modules are set up. It should be confirmed that the terminal voltages of the modules add up in series, while the currents remain the same. In the parallel circuit, however, the currents add up and the terminal voltages remain the same.

Maximum power point of a photovoltaic module

Learning objective

In this experiment, the IU characteristic curve of the solar cells will be drawn in order to determine the optimal operating point of a PV module, the “MPP”.

Description

A simple circuit is constructed with a photovoltaic module and two 220 Ω potentiometers. While varying the resistance, the changes in voltage and current are simultaneously recorded and the characteristic curves plotted.

Quality and efficiency of a photovoltaic module

Learning objective

In this experiment, the maximum efficiency of a photovoltaic module is to be determined and its change due to increasing temperature is to be investigated.

Description

Using 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.
