Cloud-Based Remote Monitoring System for Photovoltaic Systems with Electrical Load Prioritization

Power consumption nowadays is now on its peak, paving way to renewable energy technologies in order to sustain the energy demand. One proven abundant and economic source of energy is the sunlight – which can be harvested with the use of photovoltaic systems. However, excessive usage and uncontrolled environmental effects that may take place causes photovoltaic systems to get easily degraded. Hence, the development of monitoring system for PV setups are proposed. This research aims to develop a cloud-based application capable of collecting data on the photovoltaic batteries to determine its state of charge, and to effectively distribute the power on necessary loads, which are predetermined by the consumer, during power failure. The application is expected to display the batteries' state of charge, voltage, and power consumption of loads for further monitoring. The developed prototype was proven to be able to accurately measure the electrical parameters, as well as switch the loads necessary to be supplied during the specific percentage value.
