Abstract

A single-axis solar tracking system integrated with a 5kVA inverter and mobile monitoring was built. This project addresses the problem of inefficient solar energy harvesting in static photovoltaic (PV). The system aims to maximize solar irradiance capture by dynamically adjusting the PV panel's orientation to follow the sun's daily trajectory. The core components include a 12V DC motor, a linear actuator, 2 light-dependent resistor (LDR) sensors , a microcontroller (Arduino ATMEGA 328P), a 5kVA, 24V DC inverter, 8 panels rated 300watts each, which gives a total of 2400 watts and a GSM module for remote monitoring. The LDR sensors detect the sun's position, and the microcontroller processes this information to control the linear actuator, ensuring optimal panel alignment. The 5kVA inverter converts the generated DC power to AC for household or grid use. The integrated GSM module enables real-time monitoring of system parameters, such as voltage and current via a mobile application, providing remote control. This integrated system enhances energy yield, improves system reliability, and offers user-friendly monitoring, contributing to the wider adoption of solar energy.
