No. 60: Photovoltaic panels on the rooftop of a platform building of a railway station (July 15, 2012)

Business trend:
Tokyo Metro’s subway network has a total of 179 stations, some of which are aboveground stations. One of these stations has been running a photovoltaic generation system as the photo below shows. The system has a total of 108 photovoltaic panels, covering an area of about 127 square meters.

In a sunny day, it can generate 20 kW that is enough to run an escalator and illuminate the lights inside the station. In addition, it can reduce 10 tons of carbon dioxide annually. Tokyo Metro is actively installing photovoltaic panels in its stations to mitigate the image that a railway consumes lots of electricity and contribute to the nationwide efforts to save energy.
