Monitoring Solar Tracker System Dual Axis Based on The Internet of Things to Improving Solar Panel Performance

Abstract

Building a monitoring solar tracker system dual axis based on the Internet of Things (IoT) to monitor the performance of the solar tracker which can be viewed through computers and smartphones. A solar tracker is a device that allows solar panels to follow the movement of the sun to maximize sunlight reception. Through this project, the implementation of sensors that can measure important parameters such as light intensity, temperature, tilt angle, current, voltage and power generated by solar panels. The collected data is then processed and analyzed to effectively monitor the performance of the solar tracker. The NodeMCU component is used to send sensor data to thingspeak. From the test results, it was obtained that the percentage increase in light intensity was 76.1%, the current produced increased by 136.6% and the voltage also increased by 6.4%. The percentage increase in solar panel temperature was 3.07%, the voltage of solar panels decreased by 1.35%. The use of a solar tracker system dual axis that makes the position of the solar panels perpendicular to the sun increases the total power produced by the solar panels by 8.72%. The test data showed that the increase in the intensity of sunlight received by the solar panels increased the current and voltage produced, while the increase in temperature from the solar panels reduced the voltage produced by the solar panel.
