Polycarbonate observatory domes?

My wood + metal dome was destroyed in gales earlier this year. I'm in the process of building a fibreglass replacement, but an architectural supplies factory nearby can produce a 1.9 m diameter polycarbonate hemisphere at a very reasonable price - designed for outdoor use & guaranteed against solar UV damage for 10 years. Can anyone advise me on the suitability of polycarbonate as a dome material? I've not found any evidence of people using polycarb for domes on the web.
