Abstract

This research presents a comprehensive analysis of the techno-economic feasibility of utility-scale solar power projects in Nepal. With Nepal's growing economy and increasing electricity demand, the need for diverse and reliable energy sources becomes evident. This study focuses on a 5MW grid-connected solar PV plant, assessing its technical viability through site selection, design considerations, and energy yield estimation. The selection and sizing of various components, such as PV modules, inverters, transformers, LT panels, AC and DC wires, and protection devices, are carried out meticulously through calculations, including conductor selection, to facilitate power evacuation to the substation. This technical assessment will aid in understanding the technological requirements for the establishment of a solar power plant in Nepal. Additionally, the economic analysis covers capital and operational expenditures, revenue generation, and key financial indicators such as Project IRR, Equity IRR, NPV, and LCOE. Similarly, the analysis of energy generation over a 25-year period is conducted to comprehend the correlation between project size and revenue generation. By integrating technical and financial evaluations, this study demonstrates that large-scale solar projects are both technically sound and financially viable within Nepal's context. These findings offer valuable insights for developers, policymakers, and researchers, fostering informed decision-making for the country's energy future and could be part of the national strategy.
