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).
The lower the voltage the higher the loss, there is a reason power lines are hundreds of thousands volts.
What about the rails being grounded?
So if the panels are square, like 1km per day? That’s not much for an existing rail line, and when are you going to do it? There are trains rolling there all the time.
What do you think, is it still a good idea?
about 42 panels per hour. If that includes wiring somehow, that is faster than other solar. Maybe their daily productivity estimate includes scooting out of the way of other trains and less than 24 hours operation.
