Abstract

Off-grid solar power systems are increasingly vital for supplying electricity in remote and underserved regions. However, traditional off-grid systems often lack efficient fault detection, performance monitoring, and remote control capabilities. This paper presents an Internet of Things (IoT)-enabled monitoring and control architecture tailored for off-grid solar installations. The system uses distributed sensors to capture key metrics like solar panel output, battery parameters, and load consumption, and communicates real-time data to a cloud platform via lightweight communication protocols. Users can remotely visualize performance, receive alerts, and adjust operational parameters through a web or mobile interface. Experimental evaluation demonstrates improved system reliability, energy utilization, and maintenance responsiveness.
