It is certainly impressive, but I wonder how the energy production compares with the energy used for lighting the station 24/7 ?
I have seen the lighting on when daylight would appear sufficient.

The lighting is of good efficiency, but would be better still if turned off when not needed.

4,400 solar photovoltaic (PV) panels across the bridge and it is halfway there already. Here’s some more information about the project: http://www.power-technology.com/project ... ar-bridge/

It mentions sun pipes, so they might be a help. I've mentioned excessive lighting in public buildings before now over here, sometimes to good results - which, seeing as I'm paying for it, is only right.

spin alert: "It is also claimed the cells are 100% free of emissions." Oh, like nuclear power, yeah?
