Rancang Bangun Alat Monitoring Kinerja Photovoltaic Pada Pembangkit Listrik Tenaga Surya Tipe Off-Grid
ABSTRACT
The design and manufacture of an off-grid solar panel monitoring system integrated with temperature and light intensity sensors based on the Internet of Things (IoT) is discussed in this study. The background of this study stems from the need for an automatic monitoring system to determine the performance of solar power plants (PLTS) in real time without having to make manual records. The system was designed using an Arduino Mega 2560 microcontroller and an ESP8266 module, which connects various sensors, including a voltage divider for voltage measurement, ACS712 for current measurement, DS18B20 for temperature, and BH1750 for light intensity. The research methods included simulation using the Proteus application, hardware and software system design, sensor calibration, and direct testing on the PLTS system. The measurement data was sent in real-time to the ThingSpeak platform and also stored in a microSD card as a data logger. The parameters measured include voltage, current, power, light intensity, radiation, and panel temperature, which are then used to calculate the efficiency of the solar panels. The test results show that the monitoring system is capable of displaying data in real-time via a 20x4 LCD and the ThingSpeak platform with a very low sensor reading error rate (error < 5%). The IoT-based solar panel was successfully designed and functions well in reading, displaying, and storing solar panel output data in real-time.
