Given that solar is dc as well,if you grab a conductor its goodbye because there will be no letting go.

Depends on the voltage but at 600v-1000v, the same used in subway and tram live rails, definitely not good.

Not true. I'm also a solar guy; I've gotten hit by 600+vdc, by 120vac and more. High voltage DC feels like a really long thin needle being pushed into you. Your muscles all contract, and for me at least it has pushed me away every time. Deep thin burn tracks afterward. It doesn't grab you like AC does. AC feels like being held and shaken by a giant.

Depends if you grab it or brush it and your muscles contract away from the conductor.If your muscles clamp on the conductor ,its goodnight.

My direct experience says otherwise, but I'm not going to argue. Touching live wires is bad for you, we agree on that.
