The integration of Internet of Things (IoT) technology into Solar Photovoltaic (PV) systems has emerged as an effective approach for improving energy harvesting efficiency, operational reliability, and efficient system monitoring and management. This review paper provides a comprehensive analysis of multi-layered IoT applications in PV infrastructures, ranging from panel-level monitoring to intelligent power conversion. As global solar capacity surpassed 1,400 GW in 2024, the demand for real-time data acquisition and efficient system management has become critical. This study explores IoT implementation in solar PV arrays, conventional boost converters, Maximum Power Point Tracking (MPPT) units, inverters, and specialized sensor networks. It highlights the transition from conventional monitoring to IoT-enabled real-time monitoring and data-driven analysis using communication protocols such as MQTT and NB-IoT to address challenges such as partial shading, thermal variations, and power quality. Recent studies indicate that AI-integrated IoT frameworks improve system performance through predictive maintenance, anomaly detection, and performance forecasting. This review identifies key challenges such as system complexity, communication latency, and scalability, and outlines potential directions for improving IoT-based PV system performance. Overall, IoT integration represents a significant step toward efficient, reliable, and sustainable next-generation renewable energy systems.
