The solar insolation map above indicates that switzerland gets the
most sun in Europe.

Does that mean its best for PV ?

I assume the temperature of the sun is not important for PV.

It gets the most insolation at the time of the year when everyone
in Europe gets the least amount of sun. I don't know if this means
they get the most over the entire year but it's a good indication.

Yes, more sunlight means more energy produced from PV.

The temperature of the sun doesn't change significantly. The
temperature of the panels is something else entirely. At high
altitudes and/or cold climates PV panels will perform better.
PV panels get less efficient the hotter they get.

It may get the most sun but that just makes for more smog in the valleys.

I would expect you would get very little solar power unless panels were on a
mountain top.
