PV POWERED LIGHTHOUSE AND DESALINATION PLANT (PUNTA LIBECCIO)

Objetivo

To demonstrate the advantages of PV powering an isolated lighthouse, three keepers dwellings and a desalination plant.

The Punta Libeccio lighthouse is situated on Marettimo island, 40 km north west of Sicily. The lighthouse is manned continuously, and three lighthouse keepers and their families live in three dwellings near the lighthouse.
An 8.4 kWp PV array, 1300 Ah battery and regulator, provides dc power for a 1000 W lamp and rotation mechanism (25 W) at Punta Libeccio Lighthouse off Sicily. The lamp has a range of 32 nautical miles. The lamp is operational for 15 hours a day. The battery allows 10 days operation during periods of no sun.
A 9.8 kWp array with a 300 Ah battery, two 5 kVA inverters and a control system supplies ac power for a reverse osmosis seawater desalination plant. This subsystem also supplies lights, reftrigerators, a washing machine and TV in three keepers dwellings near the lighthouse. The battery allows for 3 days operation during periods of no sun. Excess energy can be cross-fed between the two systems to minimise waste.
Back-up is supplied by a new 30 kW diesel generator.
