Solar Panel Voc-MPPT?
Wondering if there is any relationship between measured Voc and MPPT performance with a 24v panel. My 12v panel has a Voc rating of 21.9 and Isc of 8.2, but I often see 8.2ish when Voc is only 20....

You can find best panel orientation with it hooked up from looking at the Trimetric for best amps (takes two people) The reason to check panel Isc with it disconnected is to compare that number with that on the Trimetric to make sure everything is working right so you are getting Isc to the battery
I found Isc was more sensitive to change in orientation than Voc but ready to learn more about how these tests turned out.
I also found Isc to be more senstive than Voc as well. But Jim Denver has the "well duhh..." solution with a tube I assume mounted perpendicular to the panel. Obvious solution when going back to my classes on optics. And it would be quick.
