Abstract
This paper presents an economic assessment of large power (from tens to hundreds kWp) PV irrigation systems in the ECOWAS region, evaluating the economic feasibility of substituting diesel-powered and grid-powered systems with PV ones. Seven countries from the ECOWAS region were considered and two irrigation operating modes were compared (pumping to a water tank or at constant pressure). Net Present Cost (NPC) values are in the 0.33-41.5â¯Ãâ¯105 $ range, Internal Rate of Return (IRR) values are in the 8-47% range and Payback Period (PBP) values are in the 2.1-10 years range. The economic savings in terms of Levelized Cost of Energy, LCOE, were also evaluated. LCOE for PV irrigation systems are in the 4.5-17.4 $cents/kWh range, which represent percentage savings of 30-84% if compared to diesel-powered and grid-powered systems.
