Techno-economic and environmental assessment of grid and solar photovoltaic microgrid supply options for isolated off-grid rural communities toward sustainable and affordable electricity in Nkoranza South, Bono East, Ghana
Summary. This study compares grid extension and solar photovoltaic microgrids for delivering electricity to isolated rural communities in Ghana. A 746 kW solar microgrid proved economically superior to a 19.5 km grid extension, with positive net present value, 24% internal rate of return, and 7-year payback period versus negative returns for grid expansion. The solar option also delivers substantial environmental benefits, preventing 31 million tons of carbon dioxide emissions over 25 years.
