Abstract:
The aim of this thesis is to optimize the photovoltaic energy generation and its use. Impedance adaptation between photovoltaic panel generator and its load means the complete transfer of available energy from source to the use. In order to increase quantity of solar energy received on photovoltaic panel surface and consequently the energy produced, we implemented a sun tracker system commanded and controlled by a hybrid tracking strategy that combines the calculation of sun position and light sensors. The results obtained have shown that the use of a solar tracker considerably increases the power received at the surface of the modules and consequently energy that can produce. Forcing a photovoltaic module to work continuously at its maximum power requires the integration of an adaptation stage that‟s controlled by a MPPT technique. This is why
we have proposed a hybrid P & O technique assisted by two techniques based on the measurement of open circuit voltage and short circuit current. The simulation results obtained were validated by experimental results obtained using an Arduino Uno microcontroller and sensors that go with it
