Review on Design and Implementation of Solar Arduino Uno Based System for Microgrids

The increasing need for sustainable and decentralized power generation has accelerated the development of microgrid technologies capable of integrating renewable resources. This study presents the design and implementation of a solar energy–based microgrid monitoring and control system using an Arduino Uno platform. The proposed system utilizes photovoltaic (PV) modules as the primary power source and incorporates sensors for real-time measurement of voltage, current, temperature, and battery state-of-charge (SOC). An MPPT-enabled charge controller ensures efficient energy harvesting, while the Arduino Uno performs data acquisition, energy management, and load-switching operations. The system communicates key operational parameters through an LCD interface and optional IoT connectivity for remote supervision. Prototype results demonstrate stable power delivery, improved energy utilization, and effective load management for small-scale microgrid environments. This cost-effective and modular architecture provides a scalable solution for rural electrification, smart energy distribution, and renewable-integrated microgrid applications, highlighting its potential for wider deployment in sustainable energy systems
