Design and implementation of real-time monitoring based on Android and HMI of PV tower system for laboratory scale

Abstract

The performance of photovoltaic (PV) cannot be described by the user, so it is difficult to anticipate when it’s undesirable or fault condition occurs. Therefore, the monitoring of PV output parameters is needed. In this case, the parameters that can be displayed are current and voltage value. The parameter data are obtained from PV tracking of the sun position by MPPT Perturb and Observe (P&O) method used in a mechanical system of the dual axis solar tracker. In this experiment, there are two monitoring methods used, which are Real-time Online Monitoring Based on Android system and Human Machine Interface (HMI) display monitoring which is controlled by Arduino Mega 2560. Both methods are expected to show the performance of PV in real-time, remotely or not. The results of this experiment are Android apps and HMI that can monitor the PV output condition. To maintain the PV system in real-time, they keep the device under the supervision and extend its lifetime for more prolonged use.
