The new solar power lab from Christiani is another impressive system for teaching photovoltaics along with its popular solar power case. The solar power lab provides students with practical understanding of bothh off-grid and on-grid technology.
Working with the individual modules, students gain a clear insight into the circuits commonly used in photovoltaics. The modules are made of stable, shatter-proof material and have replaceable sides, fronts and backs. In addition, the rear wall is transparent, so that the students can clearly see the technology inside.
The solar power laboratory - for the photovoltaic professionals of today and tomorrow!
The components of the off-grid system 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 off-grid system technology and the on-grid system 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).
Off-grid system technology and on-grid system technology:
Off-grid 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 off-grid system technology, there are
also components of on-grid system technology.
On-grid system technology
refers to a photovoltaic system connected to the (public) grid. The electricity
generated by the photovoltaic system is fed into the grid.
Learning Objectives Off-grid Systems:
Both theory and practice of the following topics can be investigated using the solar power laboratory off-grid technology:
- Measurements with the solar power circuit: Open-circuit voltage and short-circuit current at various light intensities, angles of incidence and temperatures
- Identifying the IV characteristic and the MPP
- The battery is the energy accumulator in the PV off-grid technology: Discharge protection and charging regulator; current distribution during charging and draining; internal-resistance measurements of module and battery, exhaus-tive discharge protection
- Electric circuits possible with the PV off-grid technology: Individual overvoltage protection functions; fuses, splitters and consumers
- Separate inverters: Voltage and current measurements; effi ciency and AC voltage waveforms
- Project: Develop a back-up power supply for safety lighting
- Transfer: Design, construct and test solar power off-grid technology
