1) Skin effect is of concern - but only at frequencies well above
those used for power transmission. Start thinking about it at perhaps
5 MHz up. Skin effect is actually absent at DC

[in response to another well-intentioned post from someone else...]
2) an equal diameter of stranded and solid power line passing equal
currents, shows the stranded line getting hotter, with more volt drop,
because the resistance per unit length is higher for stranded.

Please don't share knowledge with us, willing or not, unless you're
sure. There's always someone to spot a misconception.

what an absurd response!
For the willing: solid wire is intended for Ac because the current travels
thru the average of the thicknessas it alternates polarity. Dc travels on
the outside (skin effect) due to mutual repulsion of the electrons;
therefore stranded wire is best for high current loads of Dc. If the wire
is well supported and larger than necessary for the rated current AND
cheap enough vs stranded, then go with it. Otherwise, stranded.

If you have to ask that question, don't even consider the job.

Boats are wired with tinned stranded wire based on some solid
engineering.
