Actually Polycarbonate is not as noise as you think, because if they doing in the correct way, and by using a solid type, actually the polycarbonate is very "solid" and not much sound will be out.

The only problem that i consider is, polycarbonate will look dirty after sometime, that may not look so nice, but actually u can clean it when u feel that is dirty.

Another altenative suggestion will be, concrete base with roof tiles, that is totally solid. And there is another way which very modern and costly is, Tempered glass, which the lighting much batter then policarbonate, more easy to clean compare to policarbonate, but is just the cost really high compare to other.

If still back to policarbonate, there is still another way to do it, which is using solid wood to build pergola which more tropika feel, now a day, some ppl using metal to do it as well.

Yes, it is, but the cost will higher compare to metal, diff may around 30% and above

I did one, this is call pergola, but this 1 with polycarbonet finish
