Abstract: Grid-connected photovoltaic systems are becoming attractive due to the continuing decrease in the cost of PV modules and through the possibilities of integration of renewable resources generated power into the traditional power systems. The heavy dependence on expensive imported diesel for power generation in the Pacific Island Countries (PICs) makes renewable energy based systems more viable. For large buildings where electricity demand is high and the lighting and other energy needs are provided mainly by fossil fuel based grid delivered electricity, grid-tied building-integrated photovoltaics should be examined carefully to assess their technical and economic potential. This research was undertaken to design and carry out a techno-economic analysis of a 5 kWp grid-tied PV system for the C block of the Fiji National University Samabula campus. The system design was done using the software PVSYST and then technoeconomic analysis was carried out using HOMER. The net present cost of energy was estimated to be $0.69/kWh. The PV array production would meet 31 % of the electricity demand at C block at FNU. On a yearly basis, this system could feed in 1347 kWh of electricity, thus saving $469 on electricity bill at current rates. This project also outlines the many aspects of grid connected solar power system and the benefits of using PV generated electricity over conventional forms of electricity generation. However, economically it is not a viable option at current electricity tariffs.
