Abstract:
In this study, three systems of alternative energy has been proposed to replace existing 32 kW diesel generator for
supplying 24 hours electricity to rural residents in Lubuk Batu, East Coast of Peninsular Malaysia. The three
systems are PV/diesel with battery, PV/diesel without battery and standalone PV/battery system. HOMER
software is used to determine the ability of these systems based on the initial cost of the project, the total net
present cost, cost of energy and the total electricity energy production. From the results of the analysis, it was
discovered that standalone PV/battery system is the best model to replace the existing system. This system was
chosen due to the ability of supplying electricity with sufficient amount of 47,850 kWh/yr with low initial cost
( RM 327,000 ) and the lowest net present cost ( RM 687,079 ) among other systems. While the highest energy
production of 47,850 kWh in a year at the lowest cost of energy of RM 2.768/ kWh is sufficient to express that
this system also can work without depending on the price of diesel.
