Autonomous PV/battery power supply for an unmanned lighthouse (Lithari)Funded under: ENG-THERMIE 1
The aim of the project was to demonstrate the reliable operation of a PV/battery-powered flashing beacon lighthouse in Greece. The existing system comprising rotation mechanism, optical lenses, revolving oil lamp and centrifugal regulator was replaced by a new long-range static beacon system powered by a photovoltaic generator of 4,680 Wp. The battery (24 cells Varta block) has a capacity of 2,500 Ah (C100) at a nominal voltage of 48 V DC and was designed for the autonomous operation of the system for at least 10 days. A large scale measuring station according to the Ispra/ESTI guidelines for the data acquisition was foreseen for the two year monitoring campaign. Moreover a telereporting system (digisponder) is integrated to transmit data from the beacon system. The commissioning took place in July 1989. The PV-plant was in an excellent condition after four days of operation. Taking into account all the costs of permanent staff and maintenance and fuel for the old system the photovoltaic application for remote lighthouses is already in a stage of economic viability.
