Health Monitoring System of Solar Photovoltaic Panel: An Internet of Things Application

A wireless remote monitoring system for solar photovoltaic (PV) plant is proposed in this paper. It is an Internet of Things (IoT) application implemented with an objective to offer a cost-effective solution of monitoring system, which continuously presents remote energy yields and its performance either on computer or on handheld gadgets such as smart phones. A system for proof of concept is developed with eight solar panels to monitor string voltage, string current, temperature and humidity. System is controlled by CC3200 microcontroller with ARM Cortex-M4 as core. On board Wi-Fi, wireless communication enhances the system performance with reduced area and facilitates to monitor system parameters after every 30 s.
