Alongside the popular solar power case, the new solar power laboratory is a further impressive system from Christiani for teaching photovoltaics. The solar power laboratory makes it possible to learn about and comprehend both off-grid and on-grid technology by applications found in practice.

An experienced and professional educator has developed the components and the experimental set-ups together with solar engineering specialists. The comprehensive description provided for the experiments rounds of the overall didactic concept in an ideal manner. The technology used in the solar power laboratory has been matched to an optimum to the needs of practical applications in domestic engineering.

The solar power laboratory - for the photovoltaic professionals of today and tomorrow!

The components of the stand-alone technology can be combined with the other components of the Christiani Solar Power Laboratory or integrated into existing specialist rooms equipped with perforated grid walls.

The complete Christiani Solar Power Laboratory consists of a stable laboratory table with energy channel and perforated grid wall, as well as the components of the stand-alone system technology and the grid parallel technology, which can be safely stored in a roll container.

By working with the individual module bricks, the students can immediately understand the circuits commonly used in photovoltaics. The module stones are made of stable, unbreakable material and have exchangeable side, front and rear surfaces. In addition, the back wall is made of transparent material. This makes the technology "transparent" for the trainee.

The module stones are provided with standardized and embossed symbols. All connections are led to 4 mm touch-proof safety sockets on the front side. There are no electrically conductive connections from the installed practice equipment to the outside. The adhesive system on the rear side allows theory lessons on a steel wall panel and practical laboratory lessons on a laboratory grid wall without any problems. In addition to the adhesive system, the module blocks are equipped with four spring-loaded guide pins for stabilisation on the laboratory grid wall. Due to the possibility to attach the modules to steel boards, circuit diagrams can be visually clarified and better understood.

The modules of the Solar Power Laboratory comply with the latest state of the art in photovoltaic technology and the regulations that have been in force since 2008 (VDE 0100 Part 712).

Stand-alone system technology and grid parallel technology:

Stand-alone system technology refers to a self-contained photovoltaic system. The electricity generated by the photovoltaic system is used on site or stored in batteries.

In addition to the components of stand-alone system technology, there are also components of parallel network technology. Grid-parallel technology refers to a photovoltaic system connected to the (public) grid. The electricity generated by the photovoltaic system is fed into the grid.

Possible uses for the Christiani solar power laboratory:

Entire classrooms can be fully equipped with laboratory workplaces. Christiani supplies the fitments required to fully equip such specialist rooms. We will gladly help you from the concept through to its realisation. The solar power laboratory can also be installed as single workplace for learning purposes both in companies as well as in educational institutes.
