To design a photovoltaic water pumping system aimed at sustainable irrigation and evaluate its economic viability compared to diesel systems.
Designed a solar water pumping system with a flow rate of 2.4 m3/hour
Utilized HOMER software to assess feasibility and performance
Analyzed economic factors including NPV, LCOE, PBP, and IRR with actual market prices.
Achieved a Net Present Value (NPV) of ₦1.8 million and Levelized Cost of Electricity (LCOE) of ₦184.17/kWh
Demonstrated a Payback Period (PBP) of 0.7 years and an Internal Rate of Return (IRR) of 158.7%
Prevented 102 kg of CO2 emissions annually and reduced diesel fuel use by 38.9 L.
