Performance Evaluation of On-Grid Solar Power Plant in PT.Syntek Automation Indonesia Building

Abstract

Renewable energy, especially solar energy, plays an important role in creating a sustainable and environmentally friendly source of electrical energy. On-grid Solar Power Plant (PLTS) is one of the effective alternatives to utilize solar energy by converting sunlight into electrical energy, to reduce dependence on fossil energy and allow the supply of excess energy to the grid. This research evaluates the performance of the on-grid solar PV system installed in the PT Syntek Otomasi Indonesia building by assessing the performance of the existing system and redesigning it to increase energy production. The research methodology includes evaluation of the existing system performance, analysis of operational data, and comparison between various orientations and tracker types. Simulation results show that fixed tilt orientations of 3°, 5°, and 10° provide energy production of 7.47 MWh/year, 7.46 MWh/year, and 7.37 MWh/year, respectively, with an average performance ratio of 81%. This study also identified that the existing system is less than optimal in absorbing solar energy due to the variable movement of the sun's trajectory. Redesign using the E-W tracker showed a performance ratio of 80.99% and energy production of 7.88 MWh/year, while the N-S tracker resulted in a performance ratio of 80.75% and energy production of 7.84 MWh/year. These results indicate that the use of the E-W tracker is more optimal than the N-S tracker, with a difference in energy production of 0.055 MWh. These findings recommend the use of E-W trackers to improve the efficiency of the on-grid solar PV system at PT Syntek Automation Indonesia
