Techno-economic analysis of solar PV electricity generation at the university of environment and sustainable development in Ghana
ENERGY REPORTS(2024)
Abstract
The electricity indebtedness of Ghanaian schools is increasing due to the high cost of electricity in the country. As a result, the utility companies frequently disconnect the schools from the grid to force them to settle their debts. Meanwhile, the school can reduce its bills from rooftop solar PV systems, yet little attention is given. The study uses the University of Environment and Sustainable Development (UESD) as a case to assess the technical feasibility, economic viability, and potential benefits of implementing rooftop solar PV electricity in Ghanaian schools. Google Earth software was used to estimate the structure's rooftop surface areas to determine the potential energy harvest from a PV plant.In contrast, the economic analysis uses the net present value (NPV), internal rate of returns (IRR), discounted payback period (DPP) and profitability index (IP) to appraise the intended project. The results show that using rooftops of school structures can provide the needed electricity for local consumption and export excess to the grid for sales. The NPV, IRR, IP, and DPP recorded from the study are million GHS 15.15, 21%, 1.6 and 8 years, respectively. The findings highlight the potential of rooftop solar PV systems to meet educational institutions' electricity demand, exploring the possibility of exporting excess to the national grid for revenue (income generator), reducing operational costs, and contributing to a sustainable energy transition.
