Designing an Off-grid PV System for a Farm in Vanuatu

This paper introduces the design process of an off-grid photovoltaic system for a farm in Vanuatu. The installed capacity of the photovoltaic system is 228.8 kWp, the capacity of energy storage battery is 2100 kWh, and a 30 kW diesel generator is equipped as the standby power. The annual level irradiance is 6,163.2 MJ/m

on the basis of Meteonorm. Photovoltaic system produces about 279 MWh per year, which can meet the farm electricity demand. Off-grid photovoltaic system is one of the effective power supply.
