Photovoltaic power plant converts solar radiation into electricity which can be used as a source of electrical power for appliances at homes and equipment at any tertiary institution to meet their daily energy requirement. RETScreen Expert Software was used to evaluate the techno-economic and environmental sustainability of installing a grid-connect solar PV power plant. The research results revealed the annual solar radiation of 5.74kWh/m2/day; the maximum annual energy production was estimated to be 1,550.98MWh. It was discovered that March yielded maximum energy production of 146.89MWh than other months in a year. The project profitability and economic sustainability were determined with a good Internal Rate of Return (IRR) of 11.9% and a positive Net Present Value (NPV) of $681,164. The proposed solar PV power plant has a simple payback period of 11.4 years. The maximum Greenhouse Gas (GHG) emission reduction is 670.9tCO2, equivalent to 61.7 hectares of forest absorbing carbon.
