AeternaSol 400W 12V Bifacial Solar Panel kit, 2x200W N-Type 18BB A+ Grade 25.6% High Efficiency, IP68, for Camping, Homes, RV & Off-Grid

OK, so these 2 panels, totaling 400watts theoretically, apparently can only do this when cold, 25 degrees Celsius/77 F, and perfectly oriented at the summer noontime sun, maybe even at the Equator. I kid, or maybe not. Anyhow, I am getting consistent performance of 300 watts total in the critical 12-2pm hours. Copilot says this is normal, as it is over 80 degrees at noon, so the panels are "hot", my cable run is long, 95 feet from outside in the yard, discreetly routed, to my power center indoors. It is able to keep itself over 200w total until 6pm, when the long shadows start to come for it now in the fall. Supposedly I need winter temps to get top performance, but then the sun will be weaker, right? Anyway, the important thing is they arrived undamaged, and generating a reasonable amount of power. Oh yeah, the slightest palm frond shadow, when it comes, drops output of the 2 panels from 200w down to 40w, so be ready for that. I am told these panels have only 2 diodes each so a small shadow shuts down half a panel, and in series, the total output is limited to 2X the weakest panel at the time. Supposedly, even 3 diodes would reduce the collapse to 120watts, and 6 would reduce it to 180watts, which would be much better. Live and learn. Be ready to spend as much on cable as you do panels if you follow advice and use 10 AWG wire. Oh, and they survived tropical storm Isaiah, which was good. I have no idea how much 3 or 6 diode units would cost, since they don't seem to publish the diode count on these things.
