Tinjauan dan Implementasi Sistem Monitoring Solar Cell Berbasis Solar Tracking di Lingkungan Universitas Panca Marga

The  sun  is  one  of  the  stars  that  provides  numerous  benefits  for  the sustainability  of  living organisms, including being a source of renewable energy. One of the applications of solar energy is its conversion into electrical energy using solar cells. However, most currently used solar cells are static, leading to sub optimal solar energy absorption. To enhance energy absorption efficiency, a mechanical system  capable  of  tracking  the  sun's  movement,  known  as  solar  tracking,  is  required. This  research presents the design and implementation of an Arduino Uno-based solar tracking system to optimize the performance of solar cells. The system utilizes a Light Dependent Resistor (LDR) sensor and an INA219 module to monitor the voltage and current output of the 20 WP solar cell. The obtained data is processed by the Arduino Uno microcontroller and displayed in tabular and graphical forms using the PLX-DAQ application. Experimental  results  show  that  the  implementation  of  solar  tracking  improves  the  solar cell's  output, achieving  a  voltage of  19.87  V,  a  current  of  0.37  A, and  a power  output  of 7.35  Watts. These findings demonstrate that solar tracking enhances the energy efficiency of solar cells, providing a  viable  solution  for  harnessing  solar  energy  more  optimally.  The  research  contributes  to  the advancement of renewable energy technology and more effective monitoring systems.
