  1. Putting in my hypothesis right after the intro (defining "Bifacial vertical", and that text just displayed)... BENEFIT #1: Being out of full-on direct sunlight results in significantly less heat, which is improving efficiencies. (due to lower resistance?) [Nnnailed it!] BENEFIT #2: Being completely vertical inhibits dust/other participate buildup, meaning that even if they aren't cleaned often, they still generate more electricity since the typical homeowner likely doesn't clean theirs often (if ever). [I missed it if this was mentioned; maybe as I was typing my reply...] SIDE BENEFIT: Light reflected off the ground/roof further increased the output versus what was expected. (not really 'benefit' so much as an overlooked factor in their prediction) [That didn't take long to confirm this was right! 🤘] [edit: Including this, now that you've said "last chance"... The additional panel on the back is taking advantage of those mentioned electrons being knocked off, causing it to create electricity even when there's no direct OR indirect (reflected) light hitting it (scavenging "waste" energy, in a sense) . OR, possibly it's "charging" the 'evening' panel so that once the sun does swing around to it, it experiences increased efficiency temporarily; during that time, it's doing the same now for the 'morning' panel.] [Well, this definitely wasn't mentioned, but if it's possible to create a photovoltaic-substrate-photovoltaic panel that's literally double-sided (instead of two physical panels mounted back to back), this could be something to test out! A joule theif springs to mind, but that likely isn't a good analogy...] And with that... back to the video!

  2. re: I wonder if you could use shallow depth geothermal cooling, to place some metal inbetween the panels with pipes run into the ground to circulate a gas or liquid, just through air currents/fluid flow created by the different temperatures at the panel vs underground. (to prevent a need for a fan or pump [if using a liquid] on every panel, which would make them more expensive overall to buy and maintain; granted, there are automated panel washers now, so maybe it wouldn't be prohibitively more expensive... 🤷‍♂️)
