Could someone help me with this solar farm installation questions please?

[canary11]

Hello everyone, I am doing a dissertation about a solar farm dissertation and I have a couple of questions so I would appreciate if someone could clarify these questions to me.
1) What type of cables are used in a solar farm that is connected to the grid and how are they installed?
2) What type of persons are the ones installing solar farms? are they only electricians?

1, Depends on voltage and what they are connecting to. Normally it's a connection to the local DNO.

2, All the ones I've been to are untrained eastern Europeans that can't speak English and have no idea of health and safety. The inverters and transformers on the other hand are installed by qualified people. I had to sit a two week course in France and on site training before I was allowed to commission an inverter.
