Design of Rooftop Panel Performance Monitoring System using Power and External Parameter

In maintaining the maximum capability of rooftop solar panels, requires quite expensive costs, the cost of installing solar panels is not small, it requires the durability of the life of the solar panels the old one, then a monitoring system is needed to see how these solar panels are running properly. In this study, we used the PZEM 004T Module as a reading of output parameters, namely voltage, current, power, power factor, frequency, and also Kwh whose data will be processed in ESP32 microcontrollers as brains or processor units that control inputs, processes, and outputs on solar panels. Based on the test results, it is known that the monitoring system can work well to display measurement results in real-time through the blynk application. From the results of the analysis on this tool, an error value was obtained in this tool for voltage measurement, which is 0.05%, and for current measurement, which is 0.06%. In the future, it is hoped that the results of this study can be the basis for analysis to determine the service life of rooftop solar panels
