An Internet of Things system for measuring parameter of Photovoltaic Panel

Abstract

Internet of Things (IoT) system is developing at an impressive rate nowadays. It iscapable of performing machine-to-machine communication, cloud connection, datamanagement and collection simultaneously. In this paper, the authors have designed an IoTsystem in a Photovoltaic (PV) panel with real time current and voltage measurement, cloudconnection capability and measurement storage function into an IoT server. The graphical datastored allows evaluation of the PV Panel’s overall performance. Our IoT systems were poweredwith Arduino-based microcontroller paired with current and voltage sensor, as well as WIFIwireless communications system and Bluetooth module. We paired our system with an androidsmartphone to display the data and stored it into the Blynk server. Blynk is a cloud-based IoTcapable of controlling and storing data for Arduino-based microcontrollers over Wi-Fi orEthernet connection. In our experiment for 50WP PV panel, we were able to store the parameterfor over one week measurement ,that give us enough data to get the PV performance.
