I'm aiming for a string Voc of about 100V, and am gung ho for tracking - My location gets full sun starting early because of an overlooking elevation.

I've just stumbled on this tracker, and reconsidering my custom built tracker, which is similar to the large scale titan tracker - The T21 is just a whole lot more aesthetically appealing, although I'll eventually need 4 of them.

Since I don't have anything in modules yet, I started reconsidering the sharps or another panel with a little higher density, rather than the kyocera 205's I'd looked at before.  I'd like to be able to get 3.6Kw on 2 trackers for the first portion of my project, but I'm feeding Outback MX60's right now, so the string voltages can't be that high.  (If MidNight ever get's the classic out, that will be a game changer).

Suggestions on a good panel configuration to try to get 3.6Kw on two T21's with a Voc in the 85-100V range?

Also, what about wind ratings?  I'm on the colorado front range.

Hi
Sanyos would work well.  A little expensive of course.  Might be worth checking on the price of 205s though, they are less than the 210s and 215s.

Higher voltage charge controllers would help a lot.

Another option would be 6ea 230/240s per tracker.  Or 3 trackers with 8ea 230/240s and wire them in strings of 3 until the HV controllers are out then switch to strings of 4.

The T-21 is conservatively engineered for 90mph.  I know the front range has some serious wind, which is why I mentioned the possibility of 6 per tracker for some safety margin.
