Solare Roma - Italy15 MWp Photovoltaic Power Plant

SunPower designs, manufactures and delivers the highest efficiency, highest reliability solar panels and systems available today. With over 10 years of large-scale systems experience and operating data, and more than 650 megawatts of large-scale, ground-mounted solar power systems operating or under contract, SunPower is a world leader for utility-scale solar power plants.

SunPower has selected Schneider Electric as EPC contractor (Engineering, Procurement & Construction) for the construction of a park near Rome in Italy. With an output of 15 MWp, this park is made up of 47,000 panels spread across 24 hectares of land. It will produce 21,7 GWh of electric power every year, which corresponds to the electrical consumption of about 18,000 inhabitants. A park of this type represents an annual saving of 12,000 tonnes of CO2.

SunPower wanted to optimise the park construction time (6 months), and called upon a reliable and competitive player that can offer attractive technical solutions.
