This project concerns the supply of photovoltaic power to encourage tourists to visit caves of archaeological interest at two sites in Tuscany, Italy. At Cetona, a photovoltaic array of approximately 19 kWp with batteries supplies lighting for a group of caves. A system of approximately 7 kWp supplies lighting and a small drainage pump at Hildebranda's tomb near Sorano. Both systems have dc/ac inverters in order to make use of readily available, high-efficiency ac lamps. The systems have been designed to minimise environmental impact. The arrays are located out of sight and at least 500 metres from the sites. Prefabricated ballast blocks were used for the array support structures instead of excavating for foundations. The project demonstrated the suitability of photovoltaic systems for this type of sensitive environment. The two plants are now owned by the town authorities of Cetona and Sorano.
