The project consists of the implementation of solar PV generators for the power supply of two switching exchanges located in the Saintes archipelago, near the island of Guadeloupe in the West Indies. Two main parameters have been taken into account: (i) the operation reliability; (ii) the high operation cost and poor operation quality of the conventional energy sources (distribution network, battery charger, rectifier, generating set). The advantages are twofold: (i) to use the abundant solar energy, approx. 3,000 hours of sunshine per year; (ii) to avoid the maintenance of a conventional energy source (generating set). Terre-de-Haut and Terre-de-Bas, the two main islands of the archipelago, have been equipped with the following systems: (i) 184 PV solar modules photowatt providing a nominal power of 7,360 peak watts; (ii) an electronic regulation unit with sensors and alarm devices; (iii) a battery bank of 2,000 Ah under 48 volts for a storage of six days; (iv) a dc/ac, 1 kVA inverter for maintenance. Since the first operation of the generators and the coupling with the switching exchanges, energy has been provided continuously for four years.
