Well, as to your modification to point ‘B’, it’s these ‘early adopters’ with their gained cumulative total number of years (if not even decades!) of actual hands-on usage that can also state their preference as ‘experienced based’….
One could argue that some folks who have solar may not see an appreciable benefit - fair enough on that, but my best guess is that those of us who do benefit are folks that tend not to regularly camp under trees, thus I’m drawn to conclude the disparity of which you point too might best be attributed to either preferences in camping styles, too few of panels (or possibly a strictly series panel configuration?), or insufficient battery storage to carry them over to the next harvest opportunity - JMHO…FWIW, a system can be easily designed (and usually are) to tolerate a limited amount of shading, and what often happens is a reduction (if not the elimination…) of shading during those peak harvest hours…Either way, more good info for the “to go solar, or not to go solar” grist mill :)
