Abstract

Currently more than 80% of the world's energy needs are met from fossil energy sources (petroleum, natural gas, and coal). In the use of Photovoltaic, the resulting performance must be supervised in order to maintain the condition of the panel to reduce significant damage to the photovoltaic. Several studies have discussed various applications of electrical energy monitoring systems especially on photovoltaics. photovoltaic Performance Monitoring System Based Iot Using Arduino Uno on Pematang Johar has a problem formulation to know the performance of solar photovoltaics using internet methods, in order to facilitate remote surveillance. In this study, Voltage Divider, Current Sensor (ACS712), DHT22 Sensor, LDR Sensor (Light Dependent Resistor) and Blynk platform were used as sensor reading viewer. The research began with designing software and hardware circuits to test the success of the system, then designing the Blynk platform, as well as designing programs using arduino IDE software. In sending data using internet media, wi-fi module (NodeMCU) is used to send arduino reading results to Blynk platform with JSON program and the voltage sensor reading showed an error of 1.8 % on the current sensor showed an error of 3.3 %.
