#A Record-breaking Solar-Covered bridge In London Theye calling it the orld largest solar powered bridgeand who to argue? We haven seen a bigger one than the 4400-panel-covered Blackfriars rail bridge that spans the Thames in central London. The bridge is part of the London Blackfriars station that opened in 2012 in time for the Olympics making way for more and longer trains and providing station entrances on either bank of the Thames. The PV panels over the rail bridge have been in place for a while now but this week Britain rail infrastructure company Network Rail officially unveiled them in a fashion only The british could come up with: They served up nearly 80000 cups of tea an amount that could be made from the bridge average daily power output. Blackfriars Bridge London (image via Network Rail) The panels on the bridge which connects north and south London in the center of the city cover some 6000 square meters Network Rail said about 1. 5 acres. That a good-sized system adding up to 1. 1 megawatts of generating capacity. Network Rail said that at peak output the system could provide as much as half the station electricity needs and that over the course of a year it would avoid 511 tons of CO2 EMISSIONS. That said London isn the sunniest place in the world and the 900000 kilowatt-hours of annual generation forecast for the bridge means that the array of Sanyo panels will deliver a modest 9. 3 percent capacity factor. For comparison utility-scale solar arrays in the sun-drenched U s. Southwest deliver more than 25 percent capacity factors p
