Solar panels between railway tracks?

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).

It's hugely expensive, but I expect most of the cost to be in the wagon that lays panels down and picks them up - and could hopefully service a big stretch of railway (if it works). That kind of systems will cost a pretty big penny.

I doubt if this project will "fly", however. A totally horizontal solar panel at ground level is a far cry from producing energy efficiently.
