A Monitoring System of Photovoltaic Array Based on ZigBee Technology

This paper presents a monitoring system of photovoltaic (PV) array based on ZigBee technology, after a comparative analysis of different monitoring approaches. The proposed system can achieve a real-time acquisition of the PV array's parameters and the operational status monitoring via Wireless Network and Internet. In this paper, the system architecture using distributed information management is expounded as well as the hardware block diagram and functional design of the monitoring nodes, and the software workflow of the key technologies, such as data transmission and network formation.
