Solar panels will be rolled onto Swiss railway tracks ‘like a carpet’

After long delays, the removable PV system will finally be tested on a western track next spring.

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).
