Abstract

The energy produced by the photovoltaic systems is very intermittent and depends enormously on the weather conditions. This is why it is important to find a way to store this energy. This paper proposes a design and implementation of a photovoltaic power generation system controller. So as to extract maximum power from the PV panel, the proposed system controls both the boost converter and the battery charger using a microcontroller. The proposed solution is based on the PIC16F877 microcontroller. Experimental results, based on the MCU are agreed with the Matlab/Simulink simulation.
