KARAKTERISASI PANEL SURYA HYBRID BERBASIS SENSOR INA219

Abstract

Solar energy can be used as alternative energy both radiation and its thermal to meet daily energy needs. One tool that can be used is a hybrid solar cell that converts solar radiation into electricity using solar cells and combined with a thermoelectric module to convert solar heat into additional electrical power to increase the efficiency of solar energy utilization. In this study hybrid solar panels were equipped with thermoelectric generators. Current and voltage measuring devices on this hybrid solar panel use the INA219 sensor, while the control system uses Arduino Uno. The result of INA219 sensor characterization in the measurement of current strength has a relative error of 2.48% and a voltage measurement of 2.52%. The result of DS18B20 temperature sensor characterization has a relative error of 2.87%. While the results of thermoelectric generator characterization obtained that the power produced is 0.64 mW / ° C. Using thermoelectric generators can increase solar panel power by 8.22% on the first day and 6.45% on the second day.
