Objetivo To master the use of pv generators for swimming light buoys with varying orientation and inclination. To spread this technique on an international basis. To avoid the costly and dangerous handling of propane gas on the seas.The electrification of the buoys by pv generators is a complete technical and economical success. The maintenance is drastically reduced compared to the situation with gas powered buoys.Weak points are the batteries. As a result of the analysis made on 9 instrumented buoys the capacity of the batteries has been doubled to 20 days of autonomy.The inspections continue, with a frequency of at least two per year. It was found that the tight batteries have a livetime of more than five years. Statistics for the frequence of failures are available. The cost per unit of energy is calculated to be 19.8 Ecu/kWh for the demonstration project and 12.5 Ecu/kWh for replications. The total cost (operation, maintenance, investment) of the electrified buoys is about 30% of the cost of gas powered buoys.210 electrified light buoys in the North Sea, along the Channel on the Atlantic Coast, on the Mediterranean Coast around Guadeloupe and Martinique Islands and on the Guyana Coast replace existing ones, powered mainly by propane gas.Practically all 1000 buoys, operated worldwide by France, have been electrified since 1981, 210 of which were covered by the present EU subsidy.Nr. of subsystems : 210Power of subsystems : 80, 120 and 160 WpTotal power : 30 kWBackup : noneNumber of modules : 750Module description : PHOTOWATT, 12 V, double glazed, 40 W.
