Evaluation of the techno-economic and environmental viability of a solar energy initiative across the fifteen counties of Liberia

The persistent challenges posed by climate change and the depletion of fossil fuels are alarming, making it imperative to prioritize renewable energy sources. This paper presents a grid-connected photovoltaic system designed to evaluate its techno-economic and environmental viability across the 15 counties of Liberia. Simulations of the system were conducted using PVSyst and visualized in QGIS. The results indicate that Lofa county outperformed the others in terms of key performance indicators. The minimum Levelized Cost of Electricity achieved by the system was $0.0514 per kWh, reflecting the highest useful energy generated by the system, totaling 40,902.3 MWh. Additionally, the system facilitated the savings up to 14,756 tons of emissions. Notably, Lofa County recorded the best overall performance.
