Economic validation of large power PV irrigation systems

  • 1. Universidad Politécnica de Madrid

Description

This paper presents an economic evaluation of large-power PV irrigation systems (from 40 to 360 kWp) installed in Mediterranean countries, evaluating the economic feasibility of substituting or reducing their current energy sources (diesel or electrical grid) with a Photovoltaic (PV) generator and also an economic assessment based on PVIS simulated for ECOWAS region is also presented.
In the first case, five PV irrigation systems, operating in Portugal, Spain, Italy and Morocco were considered and two energetic scenarios were created in order to do the economic analysis (Optimistic and Pessimistic Scenario). The normalized Net Present Value (NPV) values are in the 2.3-3.8 €/Wp range, Internal Rate of Return (IRR) values are in the 10-16% range and Payback Period (PBP) values are in the 7-11 years range. Finally, the Levelized Cost of Energy (LCOE) values for PV irrigation systems the values are in the 0.05-0.20 €/kWh range, which represents a percentage reduction of 34-67% % if compared to the actualized cost of the previous energy source.
Regarding the second case, seven countries from the ECOWAS region were considered and two irrigation operating modes were compared (pumping to a water tank or at constant pressure). NPV values are in the 0.28-35.2x105 € range, (IRR) values are in the 8-47% range and (PBP) values are in the 2.1-10 years range. LCOE for PV irrigation systems are in the 0.04-0.15 €/kWh range, which represent percentage savings of 30-84% if compared to diesel-powered and gridpowered systems
