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).

    Aye, it corresponds with the numbers I’ve seen for photosynthesis efficiency as well. However, and here I believe we return to the root of the discussion, A: vertical solar panels in a field of crops both produce electricity and increase crop output (due to heat shelter and better moisture retention) and B: solar isn’t abundant during winter, so we need some sort of energy storage and biomass is pretty good at that.

    So, while it is not enough to offset that 40x, it will go a pretty long way of evening things out. Besides, if we produce more electricity than what is needed, the final solution, today, is to lower a heating coil into the ocean to burn off excess electricity. We will need to find energy users at the same pace we install solar, so leaving some ground for crops might not be a bad idea.

    As for the energy plan, it’s a requirement in the EED, it’s the same here.
