Paper Title
Improving PV Performance using Microcontroller-Based MPPT and Sun Tracking Systems

This paper aims to improve the performance of a photovoltaic (PV) module by using each of the maximum power point (MPP) tracker and sun tracker. The experimental implementation of both trackers is carried out in this paper. The maximum power point tracking (MPPT) system is implemented, in this work, by using AVRAT mega microcontroller and a DC-DC converter. Whereas, the sun tracking system is implemented by using the same type of microcontroller and an H-bridge. The control system of the implemented MPP tracker is designed based on utilizing the perturb and observe (P&O) peak-power tracking algorithm, which can be implemented easily in this work, and PI controller. While that of the sun tracker is designed based on utilizing the optical tracking technique, which is chosen, in this work, due to its simplicity and independence on the geographical location. Experimental results indicate that the use of the implemented trackers gives good results for both the MPPT and sun tracking systems. Keywords - DC-DC Converter, H-bridge, MPPT, Single-axis Sun Tracking.
