Design and Implementation of Efficient Low Cost MPPT Controller for Photovoltaic Application

The internet of things (loT) is an important element for remote monitoring, supervision, and quality assurance in solar photovoltaic (PV) systems. It also increases the energy production's long-term sustainability, stability, effectiveness, operation and maintenance. In this paper, a prototype for a photovoltaic generator (PVG) using the Isofoton Is-150c/12 photovoltaic modules, Arduino UNO and three different DC/DC converters with P&O algorithm to extract the Maximum Power Point Tracking (MPPT). The system is developed and tested for remote monitoring systems based on the Internet of Things (loT) methodology consider low-cost. The current and voltage output of the PVG are collected using two sensors and stored in a computer. The P&O algorithm ensures the extraction of the MPPT and transferred the maximum power generated by the PVG. The system is simulated under Simulink using boost converter, buck converter, and boost-buck converter using three different duty cycles 20%., 25% and 50%. The results are compared with the experimental data obtained using the loT interface. The comparison shows a good result between the simulation and the experimental output voltage and current using the three DC/DC converters and variable duty cycle.
