The solar panels, installed on top of the new 250-metre-long station roof, will generate an estimated yearly output of 900,000kWh when completed, providing 50% of the station’s power necessity and reducing CO2 emissions by an estimated 511 tonnes per year.
The total cost of the Blackfriars project is expected to be around £550 million, but buying and installing the PV panels probably will involve additional costs of about £7-10million.
The project started in spring 2009, but currently - July 2012 - the solar paneling is about half-way complete. Up to now, Solarcentury has installed 2,200 of Panasonic’s HIT photovoltaic modules from overall, 4,400 to be installed across 6,000 square meters on the roof of the rail bridge. Solarcentury is the UK-based company that is responsible for the construction of this project.
