You can increase the power output of bifacial solar panels by reflecting light onto the back of them. This got me thinking...what cheap white or reflective surface would increase bifacial solar panel output the most?
So I gathered 5 cheap white/reflective materials -- white rocks, aluminum foil, an emergency thermal (mylar) blanket, a white tarp, and reflective insulation -- and spent the day putting them beneath a bifacial solar panel to measure how much each material increased power output.
I wanted to compare the power output against a control, so I set up 2 identical bifacial panels and only put the reflective materials beneath one of them.
(In hindsight, I probably should have included a material to mimic putting a white fence behind the panels...but didn't think of that until I was done with filming and editing the video :/.)
Some of these materials aren't the most practical. The aluminum foil and mylar blanket, for instance, both tear easily and wouldn't last very long. But I included them anyway for fun, and I do think they were at least worthwhile to test out.

I filmed this video back in July and am just now getting around to posting it, so unfortunately I wasn’t able to incorporate or build off of their findings in this video. So, if you haven’t already, I highly recommend checking out their videos as well after watching: Everyday Dave’s video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-xD1MT-ek05w.html Everyday Solar’s video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-PL17WVBvT4c.html Also check out the video I mentioned from the channel The Kelley’s Country Life: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-i7FOsQaFi5Q.html

Do it again. Next time see what the difference is when you aren't aiming the panel directly at the sun. ie, increased relative benefits may be from the indirect light that gets behind the panel well-before and well-after peak irradiance angle. Nice video-- I like your content!
