B) Table top control panel including:
B.1) Charge regulator
B.2) Electric load
B.3) Electric instrumentation for detecting the energy flows in the different branches of the circuit
B.4) Data acquisition board with USB interface for PC connection (PV-OG/EV)
C) Buffer battery
PV-OG/EV only:
D) Solar radiation sensor
E) Temperature sensor
Operating Principle:
Training Program:
- Physical principles whereby solar power is transformed into electrical power
- Energy balance and efficiency
- Study of the Energy Flows and the related measurement devices
PC Data Acquisition (PV-OG/EV):
- The trainer is supplied with data acquisition board with USB interface for connection to PC
- A specific software (developed with LabView) is supplied to monitor the system parameters
- The visualized parameters are:
– All DC parameters
– Global solar radiation incident on the PV panel
– PV panel temperature
The software enables to:
- Calculate energy conversion efficiency
- Visualize the trend of the solar radiation incident on the PV panel and its temperature and the energy flows to and from PV panel, buffer battery and load
- Save the exercises data for future analysis or project work
