Abstract
Indonesia is a country located on the earth's equatorial line, where solar radiation is abundant throughout the year, as well as the potential energy that can be absorbed by utilizing solar cells. This research aims to maximize energy conversion and improve solar cell efficiency by requiring a solar tracker system. A solar tracker is a system used to track the direction of incoming sunlight detected by 4 light sensors (Light Dependent Resistors). This system uses solar panels, Solar Charge Controller (SCC), battery, inverter, TD8120MG servo motor as solar panel actuator, power outlet connected to relay for remote load control, and equipped with PZEM-017 sensor to monitor voltage, current, and DC electrical power through Blynk application in real time. Testing was conducted for 4 days, 2 days without tracking and 2 days with tracking. Data collection was performed every hour from 08.00-16.00 WIB, with clear and sunny weather conditions during testing. Sensor calibration results showed excellent accuracy with PZEM-017 sensor having 0% error rate for voltage and average error of 0.29% for current and power, while BH-1750 sensor showed consistency with average error of 0.15%. Based on tracking system test results, average power of 23.35 W was obtained on the first day and 20.89 W on the second day, with the highest peak power reaching 35.76 W at 12.00. Non-tracking system test results showed average power of 16.96 W on the first day and 15.83 W on the second day. The tracking system consistently produced 0.4-0.6 V higher voltage and 0.3-0.7 A higher current compared to the non-tracking system at every observation time. Based on the research conducted, the solar tracker system provides approximately 34% efficiency improvement compared to the non-tracking system, proving that solar panel output with off-grid system is more effective using a solar tracker system that can follow the direction of sun movement so that solar panel output is maximized.
