Correlating school physics with practical usage of the photovoltaic cells is a specialty of this system.

The system has been conceived in such a way that most experiments can be conducted in normal room lighting. An external power supply is not necessary for these experiments. The leXsolar lighting module (included) is required only for a few experiments - which can be operated with a student's power supply.

Additionally, the product is expandable with Measuring without Measuring Tools.

Key Data:

• Basics of photovoltaics learnable
