Wi-Fi Based Solar Plant Monitoring System

Nowadays, renewable energy systems are becoming the best way to generate electricity. Generally, the solar plants are in decentralized nature, hence it is difficult to monitor them. This paper presents a cost effective prototype for real time monitoring of the solar plant which collects the values of current, voltage and power from the sensors using Wi-Fi. The proposed system consists of two main components- the first part is the hardware interface modules where the end module receives the data through RS232 interface from string combiner. Then, it is enabled to scan, discover and connect through AP to the main module. The second part is the web server, which represents the core system that manages controls and monitor’s solar plant.
