A project very much in the public interest, the CAR (Centro Agroalimentare di Roma, Agricultural and Food Centre of Rome) spreads over an area of 114 hectares in a highly strategic location in the national road network. The structure, dedicated to commercial fish, fruit and vegetable farming, is among the most important in Europe and the largest Italian commercial distribution centre for fresh produce. We set up a major photovoltaic power unit for this “Commerce City,” a major investment in protecting the environment. The unit has a power level of 3,300.00 kWp. It is the largest entirely roof-mounted photovoltaic system in Italy.
