The increasing demand for renewable energy has accelerated the adoption of solar photovoltaic (PV) systems worldwide. However, the efficiency of fixed solar panels is limited due to the constant movement of the sun across the sky. A Solar Tracking System using Internet of Things (IoT) technology enhances energy output by dynamically aligning solar panels with the sun’s position throughout the day. This journal presents the design, implementation, and evaluation of an IoT-based solar tracking system that optimizes energy harvesting and enables remote monitoring and control.

The proposed system integrates microcontrollers, light sensors, servo motors, and IoT communication modules to track sunlight intensity and adjust panel orientation accordingly. Real-time data transmission to cloud platforms allows users to monitor voltage, current, power output, and panel position via mobile or web applications. This integration improves operational efficiency, reduces manual intervention, and supports predictive maintenance.
