Thanks compostman BUT I get a bit more sun than you!

Las Vegas solar radiation levels,

Annual Total BTU's per square meter (10 tubes): 5,693,311

Washington DC

Annual Total BTU's per square meter (10 tubes): 3,602,086

That's 57% higher solar radiation, I'd expect the plastic to degrade
faster here. Generally even treated plastics begin to fail around the
5 year mark. I have seen products, recycled, that last longer but
haven't found any reliable data.
