Energy-Neutral Cricket Stadium: The Zahur Ahmed Chowdhury Stadium, Analytical Design, and Computational Modeling

Traditional ways of generating electrical energy are expensive, harmful to the environment, need extensive maintenance, and will eventually be phased out. Therefore, it is necessary to explore the immense potential of environmentally friendly renewable energy sources. In this research, a grid-connected PV system that is efficient, durable, and good for the environment is proposed as a solution to this problem at the Zahur Ahmed Chowdhury Stadium (ZACS). Chittagong is one of the cities in Bangladesh with significant untapped solar energy potential. The global horizontal sun irradiance at our selected location is 1624.9 kWh/m², with an average of 4.45 kWh/m² per day, and the average temperature is around 26.6 °C. The system's performance ratio (PR), and also additional power losses, PV module losses, inverter, and temperature losses, are all taken into account and estimated in this study using PVSyst. Simulation yields an 85.6% PR, generating 824.5 MWh/year, with a 16% Capacity Utilization Factor (CUF). The system's implementation will curtail 11475 tons of CO2 emissions, yielding a positive environmental impact. The financial analysis evaluates various interest rates, affirming system feasibility. This innovation will greatly influence the environment and electrical industry worldwide, shaping the design, analysis, operation, and maintenance of future grid-connected systems.
