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.      

Both theory and practice of the following topics can be investigated using the solar power laboratory off-grid tech-nology:

  • 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
