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).
you have to keep the panels clean in order to work. this is not a great position to do so
could trains have some kind of mechanism that might help? physical contact seems too much, maybe a blower?
won’t really help against bird poop and such
I’m sure enough air is moved simply from the train moving by, but there will probably still be rocks and stuff flying around
