This report concerns the use of photovoltaic (PV) solar electricity sources to supply electricity to 210 marine navigation beacons in various coastal locations in France and its overseas territories. Before electrification the buoys had been powered by chemical batteries or propane gas. Each was fitted with an average of three 45 Wc modules and two 60 Ah watertight gas-recombination batteries. The beacon consists of a 10 W - 12 V lamp. A watertight casing contains the electronic circuits for power source and lamp. The batteries remain the weakest feature of the equipment, despite the marked success of the solar PV units. Investment costs are recovered in under two years. Providers of marine navigation beacons throughout the world are switching to PV power sources, whose low running costs makes them particularly suitable for developing countries where capital investment is made by Europe, the United States or Japan, or where there is no budget for operation.
