best choice of architecture is a PV+LIB configuration for
the selected location. The optimum size of the PV panel is
estimated as 6.4 kW and the rating of the storage system
will be 12 kWh to provide sufficient power backup. The
CoE of this system is US$0.2/kWh and NPC is US$7,443.
The total energy produced will be 3,607 kWh by the PV
panels. The autonomy of the proposed system will be
29.654 h. The reliability of the system is also good since the
unmet electrical demand is 2.1 kWh/year. With these
results, it can be concluded that the best choice of system
architecture is PV+LIB.
