MODELING OF AN ELECTRICAL ENERGY GENERATION SYSTEM FROM SOLAR CELL TOWARDS CARBON NEUTRALITY IN DHURAKIJ PUNDIT UNIVERSITY

Abstract

Energy systems and the energy performance of buildings play a significant role in achieving Thailand's carbon neutrality target. This research aimed to analyze the energy provision required to reach the carbon neutrality target at Dhurakij Pundit University. The PVSYST simulation tool was used to calculate and evaluate the rooftop electrical energy generation system. A survey of 22 buildings revealed that 10 of them could accommodate rooftop solar cell panels, considering factors such as building shading, non-specific building characteristics, and inappropriate rooftop areas. The study found that the installed electrical generation system from solar cells could produce 992 kWp, enabling the generation of 1,379,477.70 kWh per year. This is equivalent to approximately 4,768,470.42 Baht in annual savings, with a total investment of 32.736 million Baht and a payback period of 7 years and 3 months. The system can also reduce CO2 emissions by 651.742 ktCO2 per year. The results of this study can be applied to enhance the energy systems in conjunction with other energy-saving measures to reduce CO2 emissions in a case study. Furthermore, the findings from this study can be applied to other educational buildings as they strive to achieve carbon neutrality.
