Development of an IoT based DAQ system for PV monitoring and management

The electricity demand has been continuously increasing in recent years due to the population increase, rapid economic growth and exponential depletion of non-renewable energy sources. Renewable energy sources are heavily contributing to meet the energy demands throughout the world. Pakistan is situated in highly feasible region for solar power, as average daily sunshine is about 10-11 hours in summer and 6-7 hours in winter. However, supervision and power management of PV system is not currently deployed in Pakistan to a larger extent at most sites. Therefore, in this research work an IoT based data acquisition (DAQ) system is developed to acquire important parameters i.e., voltage, current of PV panel, battery voltage and the power being consumed by load. This data is sent to the gateway and it will be displayed on digital platform. Moreover, gateway will also produce alerts on certain critical condition of PV system and these alerts will be highlighted on the dashboard remotely. The timely intimation of problems occurrence in the PV system will ensure its reliable and efficient operation.
