PHOTOVOLTAIC SOLAR ENERGY ADVANCED TRAINER

Modular trainer for the theoretical and practical study of the electric energy generation from photovoltaic panels. With the Photovoltaic Solar Energy Advanced Trainer it is possible to perform experiments to determine the characteristics of a photovoltaic panel, study its off-grid operation with a batterycharge regulator and its on-grid operation with the connection to the mains network.
The complete system is supplied with a sun simulation module for indoor use.

TRAINING OBJECTIVES
o Measuring solar radiation: Changing the inclination and azimuth of the solar panel
o Investigating the PV module response to shadow formation
o Recording the characteristics of the solar modules: Solar Panel Voltage-Irradiation Curve, Solar Panel Current-Irradiation Curve (calculating the inner resistance of the solar panel), Obtaining the solar panel currentvoltage curve, Obtaining the solar panel current-power curve, Measurement of the voltage and current of the photovoltaic module with overload
o Off grid system: Measuring the generated power of a PV system and battery charging
o Off grid system: Using Solar Panel and Battery to supply a DC Load
o Off grid system: Design and testing of a standalone PV system in direct storage operation and 230V AC

o On grid system: Measuring the electricity delivered to the mains grid
o On grid system: Measuring the electricity produced by the solar panel, delivered/taken from the mains grid, and the loading of AC lamps
o On grid system: Determining the efficiency of the grid connected inverter
o On grid system: Investigating the response of
a PV system to a mains failure
