To get a 2" arch out of stainless, you will have a VERY heavy unit and very expensive. The reason I like the 2" diamters is for easy, multiple wire runs for multiple components.
On average, I get approximately 205-210ah/day from the units. Somtimes more, sometimes less.

CD,
Great post, coinsidering I need to build something to support my Fourwinds wind generator. There's one aspect of this that I'm wondering about.
Would you still need 2" diameter if you went with Stainless, or would you pick up some strength from the different material? (Perhaps that would allowing you to go to 1.5 inches.)
Also, how long does the polished aluminum last? In 15 years what does it look like?
