Abstract: Pacific Island Countries (PICs) encounter the challenge of not having proper infrastructure to provide electricity access to rural communities. The cost of taking the grid to the remote areas and islands is expensive which leaves no choice but to look for substitutes. Most developing countries have considered off-grid lighting products such as SHSs and SLSs as an option. Fiji, as part of the Pacific, encounters the same problem. People in the remote islands of Fiji with no grid-connectivity, are heavily dependent on the highly inefficient traditional or fuel based lighting systems which emit greenhouse gases (GHGs) and pollutants that contribute to global warming and many health related issues. A solution to these challenges is the usage of cleaner and sustainable lighting systems such as solar lighting systems (SLSs) and small solar lights with Light Emitting Diode (LED) lamps which are financially viable and robust decentralised options for providing efficient lighting solutions to rural populace. The main objective of this work is to assess the performance of different SLSs available in Fiji in terms of their solar Photovoltaic (PV) characteristics, illumination levels, system efficacy and socio economic viability. A survey of SLSs available in Fiji markets was undertaken and sample of seven lighting systems namely, Dlight S250, Sun King Pro, Nokero Light, Barefoot Connect, Solar Lantern, Solar Light 10-01 and Dlight Kiran, were tested for PV characteristics, run time and illumination distribution. The lighting systems were categorised and ranked accordingly. The most economical of the seven systems were found to be Barefoot Connect, Solar 10-01, Sun King Pro and Dlight S250 in that order. These systems possess key qualities which make them most efficient and suitable for wide use in Fiji and other Pacific countries. The second objective of this work was to carry out an impact assessment of the lighting systems that were distributed in four remote villages in Fiji. These were Namou village in Ba, Valelawa 1 & 2 and Lagalaga in Labasa.. The impact assessment was carried out by the means of a questionnaire as well as interviewing different groups of people. The first part of the survey was a group interview to determine the background of the village followed by a tour of the village. The second part was the individual and household interview which was on the technical aspects of the usage of the SLSs. The responses were recorded and an analysis was carried out to determine social and financial benefits of the SLSs over traditional fuel based systems. Findings revealed that savings in terms of fuel and money, was a core benefit for the villagers. Smaller systems could replace at least 1 to 1.5 traditional lighting systems and save approximately 2-3 litres of fuel per month. The total savings for having a small systems or combination of systems at home was in the range of $FJD17 - $FJD30 per month, with an allowance of 10% for maintenance, such as, lamp and battery replacement. iii Qualitatively, SLS provides better quality of light, increased safety, improved child performance in schools, a healthy environment with less carbon emissions and overall an improved social life.
