40 seems reasonable for 550 watts if getting full sun.
You obviously need a "contraption" for your 800w!
I managed (barely) to hang 330w on my twirler that I built to hold just the 200w, but you could just use a couple more 2 by 4s. :)
I was getting about 12.4 from the two 100s and the 8.2 from the 130 for 20.6 seen at the battery, so you would get: 800/330 x 20.6 = 50a not counting an MPPT advantage pushing that to 55a or so. (or your money back!)
