I wonder what crops can cope with the shade that is being cast by the panels. Or whether there is a clever arrangement of the panels that allows for enough light to reach the plants.
The newspiece presents him as a 'Hopfenbauer' which again is german for 'Hops Farmer'.
The separation between the solar panel fences was wide enough for a tractor, although too narrow for a combine harvester, and my impression was that it is intended to combine electricity generation with harvesting. It was a small field.
