Perencanaan dan Pembuatan Real Time Monitoring System Dari Pada Modul Active Solar Photo Voltaic Tracker Berbasis Internet Of Things

Abstract

There are still monitoring system in Solar Power Plant that do it manually using measuring and recording tools directly. This makesthe data obtained is also limited. From here the idea emerged to develop a monitoring system using the IoT concept so that monitoring onSolar Power Plant that can be monitored just by looking at the website page, so current and voltage data can be easily monitored. In addition,the resulting display is easy to analyze because the display can be digital and can be monitored with a PC or Smart Phone. This monitoringsystem is used to monitor the current and voltage of a solar power plant with solar cell capacities of 50WP, 80WP, and 100WP. The SolarPower Plant that used is an active type of solar tracker. In the application of using Solar Power Plant that, there is a current and voltagestarting from the solar cell output, accumulator output, AC load input, and DC load input. The monitoring results that have been carried out willthen be automatically sent to the Thingspeak application using the SIM800L Module. The thingspeak application will send data in the form ofnumbers and graphics in real time. By comparing the value of the measurement results on the Arduino and the Thingspeak application, thevalue of the percentage of reading errors on the measuring instrument is obtained. 3. In accordance with the tests that have been carried out,the percentage of read errors / errors can occur because of the reading accuracy of the current sensor measurements and AC-DC voltagesensors with different thingspeak applications. Each sensor has a percentage value of 0.16% AC & DC voltage sensor measurement error,1.2% AC & DC current sensor, and 2.8% data transmission observation.
