Rural communities are characterized by low energy consumption and poor load factor. The use of off-grid systems to provide electricity to these communities must be done taking into consideration the peculiar nature of rural communities to improve the utilization of the installed capacity. In many situations where off-grid technology is employed for rural electrification, community-level power supply systems could have been a better option as compared to other off-grid technologies such as the stand-alone systems. This is due to the fact that all individual loads connected to power supply systems are not used simultaneously; there is always some degree of diversity. In this paper, community-isolated grid solar PV system has been designed for Yabiw rural community. In the design, demand factor and diversity factor of 0.3 and 1.7 were considered respectively. This resulted in 82.35% reduction of daily power estimated for the community in the design of community level isolated grid system from 109.856kW to 19.386kW.
