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....

Salvo, what do you think might be the explanation for my getting 34.5 Voc (rated 37) and 8.2 Isc (rated 8.3) in 15C ambient before the panel had time outside to get hot?
I can't make it come out right using the co-efficients for temp, but it was suggested it was just low irradiance for the Voc and above rated Isc being a new panel.
In summer with panels hot, I used to get lower Voc than rated but still got Isc. That made sense wrt the co-efficients, but here in this example, it seems to be backwards with the cool panel.
