BFL, yeah, I dunno. It was at or above 6.00A every time I checked other than the first and last hour or so. Resulting in 9+ hours, 54+Ah. The sky was cloudless. Must be this pure AZ sun. :) Oh, there is some pollution haze you can see when looking at the hills. Maybe that acts like cloud edge??
I only moved them several times because I could. :) But I think you are right that 3 moves would be just fine. That's how I did it back home in IL when I first tested the setup. Maybe 4 times, if horizons are low enough.
At 0930, it is at 5.84A at 14.52v. I am going to get the batts topped off today. Hooray!
