Mitsubishi Electric Corporation has completed the installation of an almost 3 MW photovoltaic (PV) installation for Coop’s new CNNA-Prato logistic centre in Prato, Italy. Some 2895 kW of capacity has been installed on the warehouse roof, covering a surface of 21,000 square metres.

The system is expected to generate 3.2 GWh per year, which will both meet the entire energy needs of the new logistic centre and also generate an estimated 500,000 kWh excess that will be transferred to the national distribution network.

The installation on the warehouse roof has become the largest rooftop PV system on a single building in Italy. The warehouse roof was specially designed for PV installations, given that rooftop installations in Italy receive a higher feed-in tariff rate than those on the ground, and use space effectively. In addition to the rooftop system, an 11 kW system of 60 PV modules has been installed on the parking lot grounds.

Owing to the effectiveness of its PV feed-in tariff programme, the Italian PV market, which reached 258 MW in 2008, has grown to be the third largest in Europe following Germany and Spain, according to the European Photovoltaic Industry Association.
