14. Two alternative Architectures BonfiglioliPhotovoltaics The modular architecture which characterizes Bonfiglioli products enables to select the best configuration based on the characteristics of the photovoltaic plant and of the site where the product is located. Master Slave Multi MPPT • Benefits • The earliest morning start • The later evening stop • High energy conversion efficiency • Longer expected lifetime • The lowest failure effect • Benefits • The highest energy extraction level in presence of: • Non-homogeneous light exposure • Different PV modules characteristics • Other plant conditions (dirt, cable length, etc.) • Low failure effect

21. BonfiglioliPhotovoltaics Bonfiglioli Milestones in Photovoltaics • 2001 • First Bonfiglioli photovoltaic • installations in Germany • 2008 • Taking advantage from the Feed-in-Tariff applied by the biggest countries in Europe, Bonfiglioli has seized the opportunity to became an important player on the PV business. It supplied inverters for Puertollano’s plant (51 MWp) in Spain, which is still one of the largest plants in the world • 2010 • Consistently with its specialization on medium- and large-scale plants, Bonfiglioli supplied inverters for the 72 MWp solar power plant in Rovigo (Italy), Europe's largest solar farm, one of the biggest in the world. Rovigo plant The plant was officially activated in November 2010. In its first full year of operation, the system will generate enough energy to power 17,150 families and offset 41,000 tons of CO2, the equivalent of removing 8,000 cars from the road. It was erected within 6 months
