I’m all for putting solar panels all over the place, but won’t these get dusty and oily and need loads of cleaning after trains pass over?
Also, costing €623,000 over three years sounds rather expensive for just 100m (although that roughly equates to 11KW).
solar canopys are actually quite expensive. Needs a very sturdy structure to hold panels high up and deal with wind loads. Solar panels are getting so cheap, that it becomes very reasonable to lay them on the ground instead of optimal angles, higher up.
