Design and Implementation of an Intelligent Maximum Power Point Tracking Controller for Dual-Axis Solar Tracking Photovoltaic Systems

This research presents the design and implementation of an intelligent maximum power point tracking (MPPT) controller for dual-axis solar tracking photovoltaic (PV) systems. The proposed controller integrates an advanced MPPT algorithm with a dual-axis solar tracker mechanism to optimize energy extraction from PV panels. Sensor data is utilized to dynamically adjust the solar tracker's orientation and the PV array's operating point simultaneously. The system's hardware and software components are developed, including a microcontroller, sensors, motor drivers, and control algorithms. Experimental results demonstrate improved energy yield and efficiency compared to conventional fixed-axis or single-axis tracking systems.
