Techno-Economic and Environmental Analysis of Solar PV System at Sher-e-Bangla National Cricket Stadium: A Comprehensive Case Study

The proposed rooftop solar photovoltaic (PV) system at the Sher-e-Bangla National Cricket Stadium (SBNCS) demonstrates a sustainable energy solution addressing Bangladesh's energy challenges. The system has a capacity of 83.2 kWp and is estimated to generate 129.5 MWh of energy annually. This deployment reduces reliance on fossil fuels and contributes to global Sustainable Development Goal 7 (SDG7). The performance evaluation reveals a Performance Ratio (PR) of 79.4%, ensuring efficient solar resource utilization. Economically, the project involves a total investment of $101,031, achieving annual energy cost savings of $5,370. Financial feasibility metrics include a Net Present Value (NPV) of $99,131.5, an Internal Rate of Return (IRR) of 6%, and a Payback Period (PBP) of 13 years. Furthermore, the system reduces 50 tons of CO2 emissions annually, resulting in a Social Cost of Carbon (SCC) savings of $77,064 over its 25-year lifespan. The project's Levelized Cost of Energy (LCOE) is calculated as $0.03/kWh, reflecting its long-term cost-effectiveness. This analysis highlights the economic, environmental, and performance benefits of implementing a rooftop solar PV system at SBNCS, offering a scalable model for integrating renewable energy into and other stadiums and large infrastructure. This study can aid in the integration of renewable energy into the grid and assist policymakers in facilitating the future energy storage systems and expanding grid-tied operations for enhanced sustainability.
