Have you priced any of these? Copper may be cheap for how well it works.

Frankly, if you're willing to paint the pipe, then insulating is only a minor additional step. This will divorce the pipe material selection from UV resistance.

It's much more efficient in piping to use an efficient collector that's thermally sunk to relatively sparse piping. Particularly since you need about 5 m^2 of collection area to get a reasonable amount of heated water:
capacity = 100 gal/day
effective insolation = 3.3kWh/m^2/day
temp rise = 70ºF
That would be a lot of piping to get the equivalent amount of collection area.
