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).
could trains have some kind of mechanism that might help? physical contact seems too much, maybe a blower?
I’m sure enough air is moved simply from the train moving by, but there will probably still be rocks and stuff flying around
won’t really help against bird poop and such
