Recent developments in micro-grids have led to increased interest in DC distribution systems due to its high efficiency in distributing energy from renewable energy sources to DC loads. The objective of this paper is to analyse the performance of AC and DC systems in a relatively large sized 6 kW PV installation. The research data was collected from a live installation on a national school on Inis Oirr, an island off the west coast of Ireland. The results indicate that usage of a DC distribution system has lower losses compared to the existing AC system. These findings provide insights to the benefits of future DC distribution systems in large-scale micro-grids.
