Renewable energy, particularly solar energy, offers a clean and
alternative energy source to meet the energy demand for sustainable development
in the world. Due to its profitability and viability, PV net-metering scheme
has been adopted in many countries. The feasibility of implementation PV
rooftop system with net metering in residential, commercial, governmental and
industrial sectors in Iraq is demonstrated in this study. A financial model has
been developed to investigate the feasibility parameters NPV,
IRR and annual savings of 24 kWp PV system. The results
showed that increasing the capacity of the PV system in residential and
commercial buildings will lead to a profitable investment return and the
breakeven point that may make the PV net-metering projects feasible is very
close to the tariff applied for the commercial sector (10.29 $c/kWh). In the
governmental sector, the tariff needs to increase
by 35.1% to reach breakeven. However, for such net-metering scheme to be
attractive and feasible on a wide scale, it is crucial to back it with
financial support through soft loans and grants.
