The solar power case follows the generator bike and constitutes the second stage of the overall didactic concept from Christiani in the field of renewable energy. Instead of using muscles, the power for the solar power case comes from the sun.

With the solar power case, students can generate their own solar electricity by means of a solar module, and save this in the battery or use it in various circuits via the additional components. This is an entertaining way of delivering and augmenting substantiated knowledge about solar electricity generation and the components and technology of an off-grid solar power system.
