Abstract

Traditionally, remote and urban communities worldwide have been supplied electricity almost completely by fossil fuel generators to accommodate for electricity needs. Currently, the integration of renewable energy sources (RESs) into the current power generation systems can offer attractive economic and environmental merits, including considerable fuel savings and carbon dioxide emission reductions. In relation to sustainability, efficiency and economic feasibility, solar photovoltaic (PV) is one of the most promising sources of RESs which is being touted as a leading solution to long-term electrification and development problems in rural and urban parts of Pacific Island Countries (PICs). In this work, a grid-tie PV system is instigated at a residential scale. The idea of this research is not to claim the power output from the PV system but to show the feasibility of a grid-tie system at a residential scale. This will help the PICs, non-profit organisations and the government better share scarce resources towards achieving their energy goals and be in line with Sustainable Development Goal (SDG) 7, ensuring access to affordable, reliable, sustainable and modern energy for all.

Highlights

  • The acceptance of photovoltaic (PV) installations has grown rapidly in the Pacific Island Countries (PICs), creating rural electrification and leading to sustainable development with renewable energy sources (RESs) [1,2,3]

  • Being a small island nation, Fiji is heavily dependent on imported fossil fuels for its energy needs, 55% of its energy production is from RESs [1,2,3]

  • Fiji is on a mission to have 100% renewable energy by the year 2030 [4], which is in conjunction with Sustainable Development Goal (SDG) 7

Summary

Introduction

The acceptance of photovoltaic (PV) installations has grown rapidly in the Pacific Island Countries (PICs), creating rural electrification and leading to sustainable development with renewable energy sources (RESs) [1,2,3]. The increased use of fossil fuel-based electricity in the PICs is increasing the carbon footprint, but is affecting the people’s health. They suffer from the dual challenge of inadequate access to modern energy services, resulting in a high dependency on imported fossil fuels [4,5,6].
