Thoroughly informative! And conveyed in a manner which I can fully grasp
I've seen 18 volts out of this panel if its aimed correctly. That surprised me because its roughly 10X9 inches including the frame and its got some age to it as well. I do run the vehicles fan near max alot and thought I could selectively offset that draw by maintaining the battery directly with some scheme to disengage it at my discretion. Now I have some avenues to ponder.
