From Roof to Grid: A Case Study on the Technical and Economic Performance of a 27 kWp Solar PV System at University Campus

Bangladesh’s electricity use is growing rapidly, but it has limited fossil fuel reserves. This disadvantage makes it harder for the country to provide people in densely populated cities with access to reliable energy. Solar photovoltaic (PV) electricity could solve these problems by making the grid less dependent on fossil fuels, cutting carbon emissions, and encouraging businesses and institutions to switch to cleaner energy sources. This study designs and simulates a 27 kWp grid-connected solar photovoltaic (PV) system for the University of Asia Pacific (UAP) in Dhaka, Bangladesh. The system has 80 SunPower SPR-MAX2-340 modules and one Sunways STT-30KTL-P inverter. It is expected to generate 36,412 kWh of electricity every year with a performance ratio (PR) of 82.42%. The economic analysis indicates that the system is financially profitable, with a levelized cost of energy (LCOE) of 0.0613 USD/kWh and a payback period of 5 years. The environmental assessment also states that the system will reduce emissions by 503.0 tCO₂ over its lifetime. The results indicate that solar PV systems in cities in Bangladesh could be a long-term solution for meeting energy needs. The overall results show that grid-connected solar PV systems can be a viable, long-term solution for meeting Bangladesh’s urban energy needs.
