Abstract
This project presents improvement of the performance of a dual-axis solar tracking system for Maximum Power Point Tracking (MPPT) to maximize the efficiency of solar energy harvesting. The system employs Light Dependent Resistors (LDRs) to detect sunlight intensity, an Arduino microcontroller for control operations, an L298N motor driver, and a wiper motor for mechanical movement. By automatically adjusting the solar panel’s position based on the sun’s movement, the tracker ensures optimal solar exposure throughout the day. Additionally, MPPT technology is applied to continuously regulate the panel's output, ensuring it operates at its most efficient power point regardless of environmental changes. Comparative performance analysis between the tracking system and a fixed panel showed an approximate 49.2% increase in energy output. This improvement demonstrates the system’s effectiveness in enhancing solar power generation. The design also proves to be economically feasible for practical use, making it a promising solution for residential and commercial renewable energy application.
