Maximizing solar PV power plant efficiency: Enhancing design through strategic solar panel configuration and PV panel selection

The keys to achieving optimal (PV) Solar Power Generation System efficiency are the selection of suitable solar modules and the correct system configuration. The challenges in optimizing the (PV) Solar Power Generation System is posed by the varying output characteristics of solar modules. As a result, it is of utmost importance to select suitable solar modules and configure them according to inverter specifications. The aim of this research, is to optimize the PV system in the Politeknik Negeri Jakarta Library Building by taking into account the variable features of voltage and current output from various types of solar modules. The output of this research is selected solar module type and its configuration. The methodology employed in this study includes comparing output calculations from different solar modules and conducting calculation analysis to determine the most optimal combination considering the characteristics of the selected inverter. The results of the simulations and calculations show that 88 TSM DE-19 550 Wp solar modules from Trinasolar with a configuration of 4 series circuits with each series containing 22 solar modules with a total capacity of 48.4 kWp is the most optimal configuration for the SG40CX Inverter. The direction of facing the roof used is North and East with a slope following the roof which is 14 degrees.
