Anyway. I'd guess they'd do better to lay them on the ground next to those dishes, than the expense of climbing up there and fastening them to that massively expensive superstructure. Not to mention the danger to life and limb, climbing around up there.
Generally speaking it's just a mistake to mount solar panels in some difficult-to-reach expensive place.
Optimal: A large flat space near the existing grid, with generous road access and clearance. On cheap land and cheap supports. Where it can be serviced, not too far from the service center.
Those dishes fail on half of those metrics.
Nothing in Switzerland is cheap, least of all land. Practically nothing in Switzerland is flat either. What little flat land we have is used for agriculture and cities.
And yet, 99% of the people I've ever seen in the industry have no idea how any of the code they write works.
I used to ask a simple interview question, I wanted to see if potential hires could explain what a pointer or memory was. Few ever could.
