Objetivo To provide reliable and economic energy supply for the safety lights of a railway tunnel. The system is designed in such a way that it can be used for other purposes as well (Standard power supply for the railway company).The Appenino tunnel, 3875 m long, is at present not equipped with safety lights. The tunnel lies about 10 km of the next grid. For the safety maintenance and for emergency cases there are 78 niches, every 50 m, and in addition there are three larger rooms for storage of material. These locations are illuminated by fluorescent lamps (one 9 W lamp in each niche and one 40 W lamp in each one of the larger rooms).The 10 kWp pv generator is installed on racks close to the wall of the south entrance of the tunnel. The 120 V battery and the 1.6 kW inverter are installed in boxes under the array.Data monitoring is made with a S.E.I. designed data logger.Nr. of subsystems : 1Power of subsystems : 10 kWpTotal power : 10 kWpBackup : noneNumber of modules : 200Module description : ITALSOLAR (now EUROSOLARE), HM 36 MS/CE, 50 Wp, monocristalline, 423 x 940 x 35 mmConnection : 10 inseries, (120 V), twenty strings in parallel in four sub-arraysSupport : on 10 racks, zinked steel,58 deg. titled (acting as shelter for the battery and switchboard rooms).Max power tracker : noneCharge controller : special design by SEI, four regulators, type SCR.Battery : FIAMM, type 2SLA580 MONOLITE, sealed, valve regulated elements.Batt.

Total load: 1030 W. Expected total average consumption: 10 to 15 kWh/day.Monitoring: Using a 386 PC (lap top) with power supply from the inverter and 6 hours buffer battery. Hourly averages of 8 data are recorded on the hard disk of the PC.
