Spec Sheet Description
Photovoltaic Panel Trainer
Model PM-E/EV
Model PM/EV (computerized version)
This system enables experimental investigation on the conversion of solar energy into electricity exploiting the photovoltaic effect. The equipment is manufactured using real components available on the market
Description:
System configuration: stand-alone (isolated from the grid)
The system consists of:
A) Mobile silicon cell photovoltaic (PV) panel
B) Table top control panel including:
B.1) Charge controller
B.2) Sinewave inverter
B.3) Electric loads
B.4) Electric instrumentation for detecting the energy flow in the different branches of the circuit
B.5) Data acquisition board with USB interface for PC connection (PM/EV only)
C) Buffer battery
D) Solar radiation sensor (PM/EV only)
Features:
- The trainer can operate with or without the sun
- The PV panel can be used both outdoors and indoors. In case of indoor use, the lighting device is required
- The PV panel can be disconnected from the system to draw the characteristic curve (one single module, two modules – parallel connection, two modules – series connection).
- The PV panel can track the sun along two axes, to allow the comparison of the performance between a fixed installation (such as the one on the roof of a house) and an installation with tracking device
Training Program:
- Components of a stand-alone solar system for electricity production
- Effect of solar radiation on the panel output voltage
- Effect of applied load variation on the electric power produced by the panel
- Effects of shading on a real solar installation
- Photovoltaic panel energy conversion efficiency
- Battery charging system management
- Operation and efficiency of a DC/AC inverter
- Connection to portable rheostat PRH-2 for photovoltaic panel
characteristic curve construction - For PM-E/EV Solar radiation meter SORM (optional item)
PC data acquisition (PM/EV only)
- The trainer includes a data acquisition board with USB interface for connection to PC and voltage and current converters.
- A specific software (developed with LabView) is supplied to monitor the system parameters.
- Parameters displayed:
– All DC and AC parameters
– Global solar radiation incident on the PV panel
The software enables to:
- Calculate solar energy conversion efficiency
- Visualize the trend of the solar radiation incident on the
- PV panel and the energy flows to and from buffer battery, inverter and PV panel
- Draw the PV panel characteristic curves output current vs output voltage and output power vs output voltage to find out the point of panel maximum performance
- Save the exercises data for future analysis or project work
