Photovoltaic panel automated.
PHOTOVOLTAIC PANEL
The suggested system includes two photovoltaic panels, an
inverter connected to a load controller and a solar storage
battery. It enables to evaluate the devices for transformation,
transport and storage of power. The telemeasurement and
telecontrol system present on the control and supervision panel,
connected to a PC facilitates monitoring the main electrical
operation parameters: voltage, current, power factor, frequency
and consumption. It enables to control two programmable
outputs and a unit for the PC conversion: RS485/RS232.
TRAINING AND EXPERIMENT PROGRAM
Study of solar energy: calculation of the average power
developed by the sun in a particular place.
Mono and polycrystalline solar cells.
Energy balance, efficiency.
Energy storage devices and control of the battery charge.
Energy conversion and distribution.
