Useful Solar Data
Next week I'll be dry camping in Q for 3 days and this will be my first "real" solar experience. I've got 3x250W panels and a MPPT60 controller. As a learning experience what data would be useful t...

BFL,
During the time and location for my chart the sun elevation would have changed from about 47 to 50 degrees elevation. And 50 degrees is the maximum elevation so that the curve is flatter during the time of the chart than earlier.
Also since the sun evelation reaches it's maximum at 12:00 and the ambient temperature was 65F it seems likey that this increase in in sun elevation was more of a factor in the slight increase in amp output vs panel temperature during the time of the chart. However, regardless I have no way to measure panel temmperature or actual radiation levels other that as I have noted it was a blue sky.
At any rate as a solar newbie I'm pleased with this output. My goal was 45A during the summer and perhaps I'll exceed that. My hope/planning was for the 3 flat mounted panels to be equivalent to 2 panels. Nothing would be better than to exceed my conservative estimates.
