Solar systems

These systems are not connected to the national electric network and directly supply some equipment. They also have a battery system that guarantees the supply of power even during poor light hours or in the dark. These systems are technically and economically advantageous in those cases where the electric network is absent or difficult to reach. They are particularly popular in developing countries for rural users who also employ them to pump water. In Italy many photovoltaic systems have been created in order to produce electric power in rural and mountain areas, especially in the South of Italy, on the islands and on the Alps. 
At the moment the most spread devices are used to supply:

• equipment for water pumping
• radio relays, survey stations and data transmission centres (weather and seismic), telephone sets
• refrigeration systems, especially for the transport of medicines
• lighting systems
• road, port and airport signs
• supply of utilities on camper vans
• advertising systems, etc.
