Abstract
Adopting rooftop solar PV systems in various domestic and non-domestic sectors (including commercial, industrial, and agricultural) exhibits their commitment to green energy ventures. This study intends to evaluate the effectiveness of a grid-connected solar system that has been installed so far: a 6.9MWp photovoltaic (PV) system implemented at University Tun Hussein Onn (UTHM) in Batu Pahat, Johor. This green energy system was installed as a part of the Self-Consumption (SELCO) program utilizing a Supply Agreement for Renewable Energy (SARE) contract. To assess the mounted energy system's efficiency, performance monitoring was carried out between December 2021 and November 2022. By evaluating the enactment of the 6.9MWp solar system at UTHM, this present work has attempted to compile the achievement of implementation of self-consumption interms of performance analysis and financial benefits to consumer. The research finding bridges the gap between policy makers, investors, and the public regarding acceptance of the large scale Self-Consumption (SELCO). . Based on International Electrotechnical Commission (IEC) 61724 standard, this study also investigates several performance characteristics of the PV system, such as final yield, clearance index (CI), array yield, PV module efficiency, inverter efficiency, reference yield, and capacity factor (CF) performance ratio (PR). Moreover, an assessment of Carbon Dioxide ( avoidance was also conducted to quantify the amount of reduction achieved. The PV system was monitored throughout this time and generated 8529 MWh of energy. The installed PV system has shown an efficiency of 11.86 %, a final yield of 108.28 %, and a PR of 0.78, respectively. Further, the installed 6.9MWp PV system at UTHM has resulted in an annual reduction of about 5450 emissions of carbon dioxide into the atmosphere by tonnes. The 6.9MWp solar PV system also estimated to reduce 25.1 RM mil in 25 years.
