Summary:Brunei is blessed with an equatorial climate, equipped with daily amount of sunlight and good temperature overall, which allows for a good potential of utilizing solar energy for electricity generation. In household sectors, off-grid solar Photovoltaic (PV) systems are often a good choice for consumers as means to incorporate into their household for electricity generation and becomes a sustainable energy source that can help with electricity consumption. The solar PV module parameters, environmental factors, voltage regulation and conversion system as well as the implementation of battery storage system all play a big part into the performance of an off-grid solar PV system. This paper presents the design, modelling, and analysis of a 24/7 off-grid solar PV system through simulation, which includes the proposed DC-DC boost converter from a chosen solar PV module type, a battery storage system consisting of individual DC-DC buck and boost converters for charging and discharging, and the single-phase H-Bridge inverter for the DC to AC voltage inversion. The system is developed to boost and regulate DC output voltage to a peak voltage of 339 V from a PV input voltage of 4SV, which is inverted to an AC output voltage of 240 V for a 256 W resistive load.
