60 of the latest Riomay® DF120 solar panel systems cover over 20,000 sq.ft on what is probably the world's largest pergola. The Severn Centre has recently won a sustainability award from the Office of the Deputy Prime Minister. A special mention of the Riomay® DF120 solar panel system was made in the accolade. The system delivers almost 200 kW at peak on a typical June day.
